Description

  The invention described in the claims of the present application includes a cable connector including a contact to which a conductive core wire of a cable including a conductive core wire and an insulator covering the conductive core wire is connected, and the conductive core wire and the covering thereof. The present invention relates to a cable connection method in which a conductive core wire of a cable including an insulator is connected to a contact provided in a cable connector.

  Conductive core wire and its covering, such as coaxial cable, in which a conductive core wire and a grounding conductor that surrounds it through an insulator are insulated for transmission of signals between multiple electrical components, electrical devices, or electronic devices In order to interconnect the plurality of electrical components, electrical devices, or electronic devices via the cable, a cable connector to which the cable is electrically connected is used so as to perform using the cable including the insulator. There are many cases. Such a cable connector is provided with a contact formed of a conductive material to which a conductive core wire of a cable is connected.

  In what is conventionally known as such a cable connector, the electrical connection of the cable to the cable connector is generally performed using a soldering technique. That is, when the cable is electrically connected to the cable connector, the conductive core wire of the cable is soldered to the conductive contact included in the cable connector.

  Thus, when the soldering technique in which the conductive core wire of the cable is soldered to the contact is taken, especially when the cable is extremely thin and the contact is extremely small accordingly, the conductive core wire Soldering the contacts to the contacts can be a nuisance that requires great care, and it is difficult to control the amount of solder and flux to be used. There were problems such as inconvenience. Due to these problems, there is a risk that the cable connector after the cable is soldered may lack quality stability. In particular, when connecting a cable assembly for signal transmission, which has a plate shape as a whole by arranging multiple thin wire cables with extremely small diameters in parallel, to the corresponding cable connector, The problem becomes noticeable.

  Therefore, in order to avoid the above-described problems, a cable connector is desired in which the electrical connection of the cable is performed without using a soldering technique. As a cable connector in which such electrical connection of the cable is performed without using a soldering method, a connection in which the connection of the conductive core wire of the cable to the signal contact is performed by press-contact or press-fitting has already been proposed ( For example, see Patent Document 1 or Patent Document 2.)

  In the cable connectors according to these conventional proposals, a connection terminal or a terminal unit (contact) made of a conductive material supported by a wiring board or a housing included in the cable connector is provided with a lead wire pressure contact portion or a lead wire in which a slit is formed. It is assumed that a press-fitting part is provided. When the cable is electrically connected, the conductive core wire of the cable is exposed to the outside by partially peeling off the insulation covering the cable, and is provided in the connection terminal or terminal unit. By being pushed into a slit in the conducting wire press-contact portion or the conducting wire press-fit portion, the lead wire press-contact portion or the lead wire press-fit portion is pressed or press-fitted. Thereby, the conductive core wire of the cable is press-contacted or press-fitted to the connection terminal or the terminal unit, and the electrical connection of the cable to the cable connector is performed without using a soldering technique.

  In addition, conventionally, a cable connector is provided with a conductive core wire connected to the cable connector so that the signal transmission cable is electrically connected to the cable connector without using a soldering technique. There has also been proposed a cable connection method for causing a predetermined deformation in a contact (see, for example, Patent Document 3).

  In the connector device (cable connector) that is connected to the cable, a contact member that is erected on a support portion of the housing or the like under the cable connection method according to the conventional proposal. The (contact) has a pair of branch portions formed at the tip. When the cable is electrically connected to the connector device, first, the conductive core wire of the cable is exposed to the outside by partially peeling off the insulation covering the cable, and the contact member. It is put in the state pinched | interposed by a pair of branch part formed in the front-end | tip part. Next, the pair of branch portions sandwiching the conductive core wires of the cable are each deformed by being applied with an external force and displaced in a direction approaching each other. Accordingly, when the pair of branch portions in the contact member are appropriately deformed, the conductive core wire of the cable is firmly held by the pair of branch portions and is electrically connected to the contact member. The electrical connection of the cable to the connector device is performed without using a soldering technique.

JP-A-10-284147 (pages 3 to 5 and FIGS. 1 to 3) JP 2001-244015 A (pages 3 to 4 and FIGS. 1 and 2) JP 2007-48544 A (pages 6 to 8 and FIGS. 2 to 7)

  A cable connector in which connection to a conductive contact included in a cable connector for a conductive core wire of a signal transmission cable as disclosed in Patent Document 1 or Patent Document 2 described above is performed by press-contact or press-fitting In this case, the connection of the conductive core wire of the cable to the connector is performed by pressing the conductive core wire into the slit formed in the contact and press-fitting it into the slit provided in the contact. As described above, when the connection of the conductive core wire to the contact is performed only by press-contact or press-fitting to the slit formed in the contact, there is a problem that the connection of the conductive core wire to the contact is not reliable.

  For example, a situation where the conductive core wire is not sufficiently pushed into the slit formed in the contact and floats up from the slit, and the conductive core wire is not securely pressed or pressed into the contact, or the conductive core wire is excessively inserted into the slit formed in the contact. There is a possibility that a situation in which the contact or press-fitting of the conductive core wire with the contact of the conductive core wire is not performed reliably will occur. In particular, when connecting an extremely fine cable having a conductive core wire diameter of 0.1 mm or less, there is a high possibility that the cable will be cut.

  In the case of a cable connector corresponding to a cable assembly in which a plurality of thin wire cables as described above are arranged in parallel, a plurality of contacts are arranged and arranged with a narrow pitch. Thus, it is extremely difficult to press-fit or press-fit the conductive core wires of the plurality of thin wire cables into the slits formed in the corresponding ones of the plurality of contacts. In addition, each of the plurality of contacts arranged and arranged with a narrow pitch is limited in space, and therefore cannot be provided with means for firmly holding the thin wire cable to which the conductive core wire is connected. . For this reason, the thin wire cable in which the conductive core wire is connected to each of the plurality of contacts is placed in an unstable state held with a weak holding force.

  Moreover, after putting the conductive core wire of the cable between a pair of branch portions formed at the tip of the contact as disclosed in Patent Document 3 above, a pair of branches sandwiching the conductive core wire of the cable Even when a cable connection method for connecting a conductive core wire of a cable to a contact by causing a deformation to be displaced in a direction close to each other and clamping the conductive core wire of the cable is performed as follows There is an inconvenience.

  That is, when such a cable connection method is carried out, a contact standing on a support portion such as a housing in a cable connector is constituted by one end portion of a plate-like member, and a pair of branch portions is provided at the tip portion thereof. It is assumed that it was formed. In order to increase the plate thickness of the plate member, there is a limit associated with the size of the contact, and the plate thickness of the plate member constituting the contact must be relatively small. For this reason, the strength of the contact with the pair of branch portions sandwiching the conductive core wire of the cable is insufficient even if the acting direction of the external force applied to cause the deformation to be displaced in a direction close to each other is slightly deviated. However, the contact may fall from a state where the contact is properly erected with respect to the support portion, and there is a possibility that a problem that the conductive core wire of the cable is not properly held by the pair of branch portions may occur.

  In addition, even if the conductive core wire of the cable is properly held by the pair of branch portions, the thickness of the plate-shaped member constituting the contact must be relatively small, so that the pair of branches The problem is that a firm holding state of the cable with respect to the conductive core wire by the contact cannot be obtained due to the portion sandwiching the conductive core wire of the cable, and as a result, the cable itself is not held with sufficient holding force. There is also a risk of it occurring.

  In view of such a point, the invention described in the claims of the present application uses a soldering technique to connect a conductive core wire of a cable, such as a coaxial cable, to a contact having conductivity. It is possible to obtain a state in which the conductive core wire is held firmly by the contact and the cable itself is held with a sufficient holding force by the contact. When electrically connecting a cable connector and a cable having a conductive core wire, such as a coaxial cable, to a cable connector having a conductive contact, connection of the conductive core wire of the cable to the contact in the cable connector Is proper by relatively easy work without using soldering method. Can be reliably performed, moreover, with the conductive core wire is very firmly held by the contact, the cable itself to provide a cable connection method capable of obtaining a state of being held with sufficient holding force by the contact.

In this state, a caulking connection state with respect to the conductive core wire of the cable arranged in the second groove portion is taken.

In addition, a pair of mutually facing bent portions that form the first groove portion is provided at a portion extending over both the intersecting portion and the inclined portion, and a pair of mutually facing portions that form the second groove portion is provided at the bent intersection portion. It is done. Under such circumstances, the pair of mutually opposed bent portions are formed into a first groove portion formed between them, and a portion forming an intersection portion is formed by inserting a conductive core wire of the cable or an insulator covering the same.

In order to establish a caulking connection state with respect to the core wire, a deformation that is displaced in a direction close to each other is generated.

  In the cable connection method according to the present invention described above, a conductive strip-like plate material is bent and formed in the insulating housing of the cable connector, and intersects a reference surface portion and a reference surface disposed within a predetermined reference surface. The inclined portion extending in the direction to be inclined and the inclined portion extending obliquely with respect to the reference plane are connected to the intersecting portion as the bent portion with respect to the intersecting portion, and the inclined portion or the inclined portion is connected to the reference surface portion, and is inclined.

  According to the cable connector according to the present invention or the cable connection method according to the present invention, for example, in electrically connecting a cable that is a coaxial cable or the like to the cable connector, the cable connector for the conductive core wire of the cable is used. The connection to the contact with the provided conductivity is made with respect to the reference surface portion formed by bending the conductive belt-like plate material and arranged in the reference surface, the intersection portion extending in the direction crossing the reference surface, and the reference surface. The inclined portion extending inclinedly has a slanted portion connected to the intersecting portion as a bent portion with respect to the intersecting portion, and the intersecting portion or inclined portion is connected to the reference surface portion, and bent and extended from the inclined portion or intersecting portion to the reference surface. A bent plane portion arranged in the inner plane or a plane parallel to the reference plane, and bends from the bent plane portion and extends in a direction intersecting the reference plane. In a contact having a curved crossing portion, a portion forming a crossing portion and a portion forming a sloping portion in a pair of mutually opposing bent portions forming a first groove portion in a portion extending over both the crossing portion and the sloping portion In order to establish a caulking connection state with respect to the conductive core wire of the cable inserted into the first groove portion or a caulking holding state with respect to the insulator covering the conductive core wire of the cable inserted into the first groove portion, Caulking and holding against an insulator covering a conductive core wire of a cable inserted into the second groove portion at a pair of mutually opposing portions that form the second groove portion at the bending intersection, while causing deformation that is displaced in the adjacent direction. In order to establish a caulking connection state with respect to the conductive core wire of the cable inserted in the second groove portion or in a state where the cable is inserted into the second groove portion, deformation that causes displacement in directions close to each other may occur. It can be carried out by.

  In this way, a pair of mutually facing portions is provided with a pair of mutually facing bent portions forming the first groove portion and a pair of mutually facing portions forming the second groove portion in the contact provided in the cable connector. The caulking connection state with respect to the conductive core wire of the cable inserted into the first groove portion or the conductive core wire of the cable inserted into the first groove portion at the two portions where the bent portion forms the intersecting portion and the inclined portion. In order to obtain a caulking and holding state with respect to the insulator covering the wire, deformation is caused to be displaced in directions close to each other, and the pair of mutually facing portions cover the conductive core wire of the cable inserted into the second groove portion. Deformation that causes displacement in directions close to each other so as to obtain a caulking holding state with respect to the insulating material to be engaged or a caulking connection state with respect to the conductive core wire of the cable inserted in the second groove portion. Is a thing, therefore, external force causing deformation displacement in a direction close to each other to each of the pair of mutually facing bent portions and the pair of mutually facing portions are added.

  At that time, the contact intersects the reference surface portion arranged in the reference surface, the intersecting portion extending in the direction intersecting the reference surface, and the inclined portion extending obliquely with respect to the reference surface as the bent portion with respect to the intersecting portion. In addition to a pair of mutually opposed bent portions provided at a portion extending over both the intersecting portion and the inclined portion, the intersection portion or the inclined portion is assumed to be connected to the reference surface portion. Even if the direction of the applied external force is slightly deviated, it is possible to avoid a situation in which an undesired displacement or deformation occurs in the contact. As a result, the pair of mutually opposed bent portions reliably sandwich the conductive core wire of the cable or the insulator covering it. In addition, the cable is sandwiched between the conductor core wire or the insulator covering the cable by the pair of mutually opposed bent portions provided in the contact at two places, that is, the crossing portion and the inclined portion connected to the crossing portion. Therefore, even if an external force is applied to the conductive core wire of the cable sandwiched between the pair of mutually opposed bent portions or the insulator covering the same, even if an external force is applied to be separated from the mutually opposed bent portions. As a result, the possibility that the pair of mutually opposed bent portions will be displaced or deformed and the possibility that the conductive core wire of the cable will be detached from the pair of mutually opposed bent portions are remarkably reduced.

  Further, in addition to sandwiching the conductive core wire of the cable or the insulator covering the cable by the pair of mutually facing bent portions, the pair of mutually facing portions further includes an insulator or cable of the cable covering the conductive core wire of the cable. Hold the conductive core wire securely. Therefore, even if the cable is the above-described thin wire cable, a pair of mutually facing bends are formed on the conductive core wire of the cable sandwiched between the pair of mutually facing bent portions and the pair of mutually facing portions or the insulator covering the same. When an external force is applied to separate the cable or the pair of mutually opposed parts, the conductive core wire of the cable or the insulator covering the same is separated from the pair of mutually opposed bent parts or the pair of mutually opposed parts. Is definitely avoided.

  Note that the cable connector according to the present invention or the cable connection method according to the present invention is a known cable connector or cable connection method in which a contact is pierced from the outside into the cable insulation and contacts the internal conductive core wire. Even in the cable connector according to the present invention or the cable connection method according to the present invention, the conductive core wire is eccentric in the covering insulating material as found in the conventional cable connector or cable connection method. This eliminates the problem that the contact does not properly contact the conductive core wire, or the problem that the contact cannot sufficiently penetrate the coating insulating material and the contact does not properly contact the conductive core wire. Benefits are gained.

  Therefore, according to the cable connector according to the present invention, the connection of the conductive core wire of the cable to the contact provided in the cable connector is appropriately and reliably performed by a relatively easy operation without using a soldering technique. In addition, a state in which the conductive core wire is held extremely firmly by the contact is obtained, and the cable itself is held by the contact with a sufficient holding force. Further, according to the cable connection method of the present invention, when electrically connecting a cable having a conductive core wire to the cable connector, the connection of the conductive core wire of the cable to the contact in the cable connector can be performed without using a soldering technique. It is possible to carry out properly and reliably by a relatively easy operation, and furthermore, it is possible to obtain a state in which the conductive core wire is held extremely firmly by the contact and the cable itself is held by the contact with sufficient holding force. .

Thus, it is possible to cause each of the pair of mutually opposed bent portions 33 to be deformed so as to be displaced toward each other.

  Similarly, in the pressing device 41 shown in FIG. 13, when moved in the a direction, each of the plurality of contacts 16 is in contact with a pair of mutually facing portions 35 provided on each of the contacts 16.

  Next, as shown in FIG. 14, the pressing device 40 provided at a position separated from the cable connector 10 and the plurality of cables 14 in the state shown in FIGS. 3 and 4 is moved in the direction a, The pair of inclined surfaces 42 of the plurality of pairs of inclined surfaces 42 formed on the pressing device 40 are brought into contact with a pair of mutually opposed bent portions 33 provided on corresponding ones of the plurality of contacts 16. Subsequently, the pressing device 40 in which each pair of inclined surfaces 42 abuts on a pair of mutually opposed bent portions 33 provided on a corresponding one of the plurality of contacts 16 is further moved in the direction a. The pair of mutually opposed bent portions 33 provided on each of the plurality of contacts 16 is subjected to a pressing force in a direction that forms an inclination angle with respect to the virtual reference surface 26 on which the reference surface portion 27 of the contact 16 is disposed. By acting, as shown in FIG. 14, the pair of mutually opposed bent portions 33 are deformed to be displaced in directions close to each other.

A pressing force in a direction forming an inclination angle is applied to each of the pair of mutually facing portions 35 provided in each of the plurality of contacts 16 with respect to the virtual reference surface 26 on which the reference surface portion 27 of the contact 16 is disposed. Thus, as shown in FIG. 15, the pair of mutually facing portions 35 are deformed to be displaced in directions close to each other. This causes the pair of mutually facing portions 35 that have been deformed to be displaced in the directions close to each other to take a caulking holding state with respect to the intermediate insulator 20 of the cable 14 disposed in the groove portion 34 therebetween.

  Each of the pair of mutually opposed bent portions 33 provided on the contact 16 is deformed so as to be displaced in a direction close to each other, so that a portion that forms the intersecting portion 28 and a portion that forms the inclined portion 29. The caulking connection state with respect to the conductive core wire 19 of the cable 14 disposed in the groove portion 32 between the pair of mutually opposed bent portions 33 is taken in the place, and the pair of mutually facing portions 35 provided on the contact 16 A state in which each of them deforms in a direction close to each other and takes a caulking holding state with respect to the intermediate insulator 20 of the cable 14 disposed in the groove portion 34 between the pair of mutually facing portions 35 is as follows. , Taken for all of the plurality of cables 14.

It is electrically connected to a cable connector 10 comprising an insulating housing 11 provided with contacts 16.

  Thereafter, each of the pressing device 40 and the pressing device 41 is moved in the direction b and returned to a position separated from the cable connector 10 and the plurality of cables 14.

  In this manner, when the plurality of cables 14 are electrically connected to the cable connector 10 including the insulating housing 11 provided with the plurality of contacts 16, each of the plurality of contacts 16 is as shown in FIG. 1. In addition, a pair of mutually opposed bent portions 33, which are deformed to be displaced toward each other when a pressing force is applied by the pair of inclined surfaces 42 formed in the pressing device 40, each groove portion 32 is formed. The contact cores 19 of the cable 14 disposed in the groove portion 32 are caulked and clamped at two locations, ie, the portion forming the crossing portion 28 and the portion forming the inclined portion 29 in the contact 16. It is supposed to be. As a result, the conductive core wire 19 of the cable 14 is electrically connected to the contact 16 (caulked connection).

  Further, as shown in FIG. 1, each of the plurality of contacts 16 is subjected to a pressing force by the pair of inclined surfaces 43 formed in the pressing device 41, thereby causing deformation that displaces in a direction close to each other. The pair of mutually facing portions 35 are configured to crimp the intermediate insulator 20 of the cable 14 disposed in the groove portion 34 so that the portions forming the respective groove portions 34 are close to each other. As a result, the intermediate insulator 20 of the cable 14 is firmly held (caulked and held) by the contact 16.

  In other words, the pair of mutually opposed bent portions 33 in the contact 16 is provided in a portion extending over both the intersecting portion 28 and the inclined portion 29, so that the pair formed in the pressing device 40 is paired with the pair of mutually opposed bent portions 33.

The pair of mutually opposed bent portions 33 reliably holds the conductive core wire 19 of the cable 14. Further, the holding of the cable 14 with respect to the conductive core wire 19 by the pair of mutually opposed bent portions 33 is performed by caulking at two locations, that is, a portion that forms the intersecting portion 28 and a portion that forms the inclined portion 29 connected thereto. Even if an external force is applied to the conductive core wire 19 of the cable 14 sandwiched between the pair of mutually opposed bent portions 33 so as to be separated from the pair of mutually opposed bent portions 33, The possibility that the mutually opposed bent portion 33 is displaced or deformed and the possibility that the conductive core wire 19 of the cable 14 is detached from the pair of mutually opposed bent portions 33 are remarkably reduced.

  Furthermore, in addition to the above, when a pressing force is applied to the pair of mutually facing portions 35 provided in the contact 16 by the pair of inclined surfaces 43 formed in the pressing device 41, the cable formed by the pair of mutually facing portions 35 14, the intermediate insulator 20 of the cable 14 is caulked, and the pair of mutually facing portions 35 firmly sandwich the intermediate insulator 20 of the cable 14. Thus, even if an external force is applied to the intermediate insulator 20 of the cable 14 sandwiched between the pair of mutually facing portions 35 so as to be separated from the pair of mutually facing portions 35, the intermediate insulator 20 is paired with each other. The possibility of detaching from the portion 35 is significantly reduced.

After that, for example, by a pair of inclined surfaces 43 formed in the pressing device 41 shown in FIG. 13, a pressing force in a direction that forms an inclination angle with respect to the reference surface 26 is applied to each of the pair of mutually facing portions 35. Thus, a deformation that is displaced in a direction close to each other is generated, and thereby, a pair of mutually facing portions 35 are caulked and connected to the conductive core wire 19 of the cable 14 disposed in the groove portion 34 therebetween. . Along with this, for example, the pair of inclined surfaces 42 formed in the pressing device 40 shown in FIG.

By causing the deformation to be displaced in directions close to each other, the pair of mutually opposed bent portions 33 are paired with a pair of portions that form the intersecting portion 28 and a portion that forms the inclined portion 29. The caulking connection state with respect to the conductive core wire 19 of the cable 14 disposed in the groove portion 32 between the mutually opposing bent portions 33 is taken. In addition, for example, a pair of inclined surfaces 43 formed in the pressing device 41 shown in FIG. 13 is used to push each of the pair of mutually facing portions 35 in a direction that forms an inclination angle with respect to the reference surface 26. A pressure is applied to cause a deformation that is displaced in a direction close to each other, and thereby, a caulking connection to the intermediate insulator 20 of the cable 14 disposed in the pair of mutually facing portions 35 in the groove portion 34 therebetween.
