Description

Connecting device

The present invention relates to a connector, in particular to a connecting device.

Referring to FIG. 1 , there is an existing coaxial cable 1, which includes an inner core wire 11, an insulating layer 12 wrapped around the inner core wire 11, an outer conductive layer 13 wrapped around the insulating layer 12, and an insulating layer 14 wrapped around the outer conductive layer 13. When the coaxial cable 1 transmits a signal, the outer conductive layer 13 is usually grounded. The outer conductive layer 13 surrounds the outer side of the inner core wire 11, thereby generating a shielding effect on the signal transmitted by the inner core wire 11, thereby optimizing the quality of signal transmission.

However, with the rapid development of technology, the demand for signal transmission has not only increased dramatically, but also the requirements for signal quality have become increasingly higher. Therefore, although the coaxial cable 1 is more capable of meeting the needs of high-speed signal transmission, the outer side of the inner core wire 11 needs to be covered with the outer conductive layer 13, which also limits the terminal connection of the connection, thereby making the related applications relatively limited. In particular, in response to the current demand for greater transmission, multiple coaxial cables 1 are used in a single wire. Considering that each outer conductive layer 13 must completely cover the corresponding inner core wire 11 in order to truly exert its shielding effect, in addition to the problem that the wires may be bulky and difficult to freely extend and flexibly connect when multiple coaxial cables 1 are bundled together, the difficulty of proper configuration at the connection terminal is also increased.

Therefore, the purpose of the present invention is to provide a connection device that can cope with the diversified configuration of coaxial cable terminal connection.

Therefore, the connection device of the present invention includes a housing unit having a connector surrounding a configuration space defining a connection direction, a conductive connection unit penetrating the configuration space, and a cable unit connected to the conductive connection unit.

The configuration space of the connector of the housing unit has an external port and an internal port opposite to the external port.

The connecting unit includes a plurality of insulating layers spaced apart from each other, a plurality of conductive layers respectively disposed between two adjacent insulating layers, and a plurality of connecting arms deformably extending from the conductive layers toward the external port.

The cable unit is connected to the conductor unit from one side adjacent to the inner port.

The effect of the present invention is that the conductive unit can adjust the appropriate relative connection position according to the number of wires, connection requirements, etc. of the cable unit through the configuration of the insulating layers and the conductive layers, and form a connection point that is conducive to corresponding connection with the rear-end equipment through the connecting arms, thereby forming a connector that can complete a proper connection with the rear-end equipment, so that it can cope with the diversified configuration of the coaxial cable terminal connection.

Before the present invention is described in detail, it should be noted that similar components are represented by the same numbers in the following description.

Referring to FIG. 2, a first embodiment of the connection device of the present invention is shown. The first embodiment includes a housing unit 2 having a configuration space 200 defining a connection direction D, a conductor unit 3 passing through the configuration space 200, and a cable unit 4 connected to the conductor unit 3. Referring to FIG. 2 and FIG. 3 at the same time, the configuration space 200 has an external port 201 and an internal port 202 opposite to the external port 201. Specifically, the external port 201 is a side facing a terminal device 9 (see FIG. 5) to be connected, and the cable unit 4 is connected to the conductor unit 3 from a side adjacent to the internal port 202.

The housing unit 2 includes a connector 21 defining the configuration space 200, a plurality of elastic elements 22 disposed on the connector 21, a stop plate 23 connected to one end of the elastic elements 22 away from the connector 21 and formed with a plurality of parallel and spaced through slots 230, and two positioning hooks 24 connected to the connector 21 and located at opposite sides and suitable for mutual positioning with the terminal device 9. The connector 21 has an outer end surface 211 surrounding the outer port 201 and an inner end surface 212 surrounding the inner port 202. The elastic elements 22 are disposed on the outer end surface 211 and can accumulate an elastic restoring force when the stop plate 23 is subjected to an external force toward the connector 21.

The conductive connection unit 3 includes three insulating layers 31 spaced apart from each other along an auxiliary line L, two conductive layers 32 respectively disposed between two adjacent insulating layers 31, and a plurality of connecting arms 33 extending transversely and obliquely from the conductive layers 32 toward the external port 201 along the plugging direction D and capable of deforming along the plugging direction D. In the first embodiment, the plurality of connecting arms 33 extending from a specific conductive layer 32 are formed integrally with the conductive layer 32. The positions of the connecting arms 33 correspond to the through slots 230 of the limiting plate 23, that is, the terminal device 9 to be connected in the first embodiment can be electrically connected to the connecting arms 33 through the through slots 230 of the limiting plate 23.

The cross-sectional area of a portion of the conductive unit 3 along the insertion direction D on one side opposite to the connecting arms 33 is larger than the configuration space 200, and is used to abut against the inner end surface 212 when the conductive unit 3 is inserted into the configuration space 200. Therefore, when the conductive unit 3 is inserted into the configuration space 200 from the inner port 202, the conductive unit 3 cannot be inserted into the configuration space 200 until the cross-sectional area is larger than the configuration space 200, thereby ensuring the relative position of the conductive unit 3 when it is inserted into the configuration space 200. In addition, each of the insulating layers 31 located at the outermost side along the auxiliary line L has a connection groove 310 that penetrates in a direction parallel to the auxiliary line L and faces the adjacent conductive layer 32, so that a portion of the conductive layers 32 can be exposed through the connection groove 310 in a direction parallel to the auxiliary line L.

Referring to FIG. 4 and FIG. 2 , the cable unit 4 includes four signal lines 41 connected to the corresponding conductive layers 32 through the connection slots 310. In the first embodiment, each of the conductive layers 32 can pass through the connection slots 310 and connect to the two signal lines 41 when the two signal lines 41 are arranged in the corresponding connection slots 310. After the cable unit 4 and the conductive unit 3 are connected as expected, the configuration and assembly of the first embodiment can be completed. Subsequently, the connector 21 of the housing unit 2 is inserted into the corresponding slot of the terminal device 9, and the connecting arms 33 can respectively correspond to the multiple electrical contacts 91 of the terminal device 9, so that the first embodiment can truly play the function of the connector.

It should be particularly noted that the first embodiment can adjust the appropriate relative connection position through the configuration of the insulating layers 31 and the conductive layers 32 of the conductive unit 3, in accordance with the number of wires of the cable unit 4, the connection requirements, and other diversified forms, and form a connection point that is conducive to corresponding connection with the terminal device 9 through the connecting arms 33, thereby forming a connector that can complete a proper connection with the terminal device 9. In addition, the signal lines 41 of the cable unit 4 are coaxially arranged and can indeed form the required coaxial cable structure, so the first embodiment can indeed cope with the diversified configuration of the coaxial cable terminal connection.

Referring to FIG. 5 , when the first embodiment is plugged into the terminal device 9, the terminal device 9 pushes against the limit plate 23, causing the limit plate 23 to move in the direction toward the outer end surface 211 of the connector 21, and compressing the elastic elements 22. Since the thickness of the limit plate 23 and the distance between the limit plate 23 and the outer end surface 211 are designed to match the distance that the connecting arms 33 extend beyond the outer end surface 211, when the positioning hooks 24 are fixed to the corresponding structures of the terminal device 9, the terminal device 9 also pushes against the limit plate 23 at the same time until the corresponding electrical contacts 91 are in contact with the connecting arms 33. At this time, through the limiting effect of the limiting plate 23, the terminal device 9 is prevented from excessively squeezing the connecting arms 33 along the plugging direction D, thereby preventing the connecting arms 33 from generating a deformation amount exceeding their own deformation margin. In addition, the elastic restoring force accumulated by the elastic elements 22 due to squeezing can be released as long as the positioning hooks 24 are separated from the corresponding structure, so that the first embodiment and the terminal device 9 are separated from each other.

Referring to FIG. 6 in conjunction with FIG. 4 and FIG. 5 , it is worth noting that each of the connecting arms 33 has a connecting end 331 connected to the corresponding conductive layer 32 , and a contact end 332 opposite to the connecting end 331 . Considering that the specifications of the electrical contacts 91 of the terminal device 9 corresponding to the arms 33 are fixed and cannot be changed, in order to make the first embodiment more versatile and achieve the desired effect of meeting multiple needs, the distance between the adjacent connection ends 331 of the arms 33 can be different from the distance between the contact ends 332 through the bending shape of the arms 33, thereby overcoming the problem of the difference between the distance between the connection ends 331 of the arms 33 and the distance between the electrical contacts 91, so that the contact ends 332 can achieve "distance shift" compared to the connection ends 331 to cope with the specification differences of various devices to be connected.

Referring to FIG. 7, a second embodiment of the connection device of the present invention is shown. The difference between the second embodiment and the first embodiment is that the cable unit 4 further includes two grounding wires 42. In order to connect the cable unit 4 to the ground, the connection unit 3 has three layers of the conductive layer 32, and two of the conductive layers 32 are the same as the first embodiment, which are signal parts 32s for transmitting signals, and one layer of the conductive layer 32 between the signal parts 32s is a grounding part 32g. The projection range of the grounding part 32g along the direction parallel to the auxiliary line L overlaps with the signal parts 32s, thereby generating a shielding effect along the direction parallel to the auxiliary line L for the signal parts 32s.

Referring to Figures 8 and 9, in the second embodiment, in order to cope with the configuration of the grounding wires 42 of the cable unit 4, the conductive unit 3 further includes a plurality of conductive members 34 connected between the grounding portion 32g and the signal portions 32s in a direction parallel to the auxiliary line L. Each conductive member 34 has a contact portion 341 extending to one of the connection slots 310, and the grounding wires 42 can be connected to the contact portions 341 of the conductive members 34 through the connection slots 310, thereby enabling the grounding wires 42 to be electrically connected to the grounding portion 32g through the conductive members 34. In addition, the second embodiment can achieve the same effect as the first embodiment.

In summary, the connection device of the present invention can cooperate with the terminal equipment 9 to be connected, the number of wires of the cable unit 4, the connection requirements, etc., by adjusting the configuration of the insulating layers 31 and the conductive layers 32 of the conductive unit 3, so that the connecting arms 33 form connection points that are conducive to corresponding connection with the rear-end equipment, thereby forming a connector that can be properly connected to the terminal equipment 9, so it can cope with the diversified configuration of the coaxial cable terminal connection. Therefore, the purpose of the present invention can be achieved.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present invention.
