Description

The The present invention relates to a shielded connector and to a method for connecting a shielded connector a shielded cable, in particular a crimping process.

In recent years, there has been a tendency to make a variety of electrical devices smaller. There is a need to make shielded connectors smaller to make parts of the electrical devices smaller. A shielded connector for connecting a shielded cable consisting of an inner conductor for transmitting a high frequency signal and an outer conductor to shield the inner conductor must separately connect the inner and outer conductors. A known shielded connector of this kind is disclosed in Japanese Unexamined Utility Model Publication No. 5-27983. This connection 1 is provided with three crimping portions: an inner conductor crimping portion 1a an outer conductor crimping section 1b and a cladding crimping section 1c like this in 7 is shown.

A shielded cable 2 and the shielded connector 1 are connected as follows. An inner conductor 2a is by stripping off an envelope 2c , the manager 2 B and an insulating element 2d exposed at one end of the shielded cable, and the inner conductor crimping section 1a is at the exposed inner conductor 2a established. Subsequently, only the envelope or the jacket 2c at this end of the shielded cable 2 stripped off to the outer conductor 2 B expose and the outer conductor crimp section 1b will be at this exposed section 2e of the supervisor 2 B attached. Finally, the wrapping crimping section becomes 1c at the serving 2c at the end of the shielded cable 2 attached, behind the exposed section 2e is arranged.

Generally, crimping portions which are attached utilize the plastic deformation of metal members, which inevitably undergoes little recovery after crimping. As a result, the attached crimping portions can be slightly loosened. If the exposed section 2e the shielded cable 2 As is fixed in the prior art, the crimping portion remains loosened when it is reset after crimping, since the outer conductor 2 B the hard insulating element 2d at the exposed section 2e surrounds. Therefore, a fastening force is insufficient.

In the construction of the known outer conductor crimping section 1b Crimping is performed without any play between the ends of the outer conductor crimping section 1b remains as in 8 (a) shown when the exposed section 2e the shielded cable 2 which has a corresponding small diameter, is connected, whereas the ends of the outer conductor crimping section 1b are spaced after crimping, when a cable having a larger diameter, as shown in FIG 8 (b) is shown. Accordingly, the outer conductor becomes 2 B loose due to the play, by the attachment by the outer conductor crimping section 1b is loosened. Therefore, it is essential to additionally route the cable through the cladding crimping section 1c to keep.

The above known connection 1 must have a long length since it has the inner conductor crimping section 1a , the outer conductor crimping section 1b and the wrapping crimping section 1c for the connection with the shielded cable 2 having. The longer length of the shielded conductor 1 disadvantageously leads to a longer length of a connector housing (not shown) to accommodate this.

It can be envisaged the serving crimp section 1c omit or remove and directly the crimping or crimping construction (see 9 ) of the cladding crimping section 1c according to the prior art at the exposed portion 2e apply. In such a case, the wrapping crimping portion forms 1c the crimp construction according to the prior art, a game or a free space, as in 10 is shown. As a result, sufficient electrical connection is not achieved and the fastening force becomes insufficient due to the aforementioned recovery of the crimping portion. This requires provision of the outer conductor crimping portion 1b and the cladding crimping section 1c , which disadvantageously makes the overall length of the shielded connector longer.

Furthermore, document reveals EP 0 510 264 A a shielded connector including an inner terminal, an outer terminal and a dielectric plug. This shielded connector comprises three crimping portions, namely, a first crimping portion of the inner terminal for crimping the insulating member of the coaxial cable, a second crimping portion of the inner terminal for crimping on the inner connector, and a third crimping portion of the outer terminal for crimping on the outer connector. Thus, this shielded connector requires at least three crimping sections arranged in series.

The The aim of the invention is to provide a new shielded connector, which can be dimensioned smaller, improved usability and has a facilitated assembly, and a corresponding Method for connecting a shielded connector to a shielded cable available to deliver.

This Target can be through a shielded connector, which has the characteristics has, as defined in claim 1, and a corresponding Be achieved method, which has the features as shown in Claim 4 are defined.

Further Developments of the invention are defined in the dependent claims.

According to the invention a shielded connector according to claim 1 is provided.

Accordingly can, since the crimping or crimping section to the outer or outer conductor is or is, the over the serving of the shielded cable folded back is, he will be attached while the serving squeezed or pressed being, being the elasticity the serving is being used. Even if the crimping section after crimping reset again becomes, the elastic deformation of the sheath or sheath is not Completely deleted or lifted, since the crimping section holds the envelope squeezing. Therefore can the serving and the leader, the above folded back is tightly held by the crimping section.

There the crimping section has sufficient fastening force and electrical Connection available It can be used both as the serving crimp section as well the outer conductor crimping section the shielded connector according to the state to serve the technique. As a result, the total length of the Shielded connector shortened become.

Accordingly can, as the pair of crimping or crimping pieces, the outer surface of the outer, over the wrapping fold back Conductor surrounded, an electrical connection more secure over the entire circumference can be formed and the fastening force can be further increased.

Furthermore, the shielded connector with different shielded Cables of different outer diameter by adjusting the overlapping Length of Ends of the crimp pieces interact or handle them.

Preferably The at least two crimping or crimping pieces extend from a soil surface of the crimping section while they are further spaced from each other to the front ends thereof. Accordingly, the shielded cable is easier to use because there is a risk of interaction with the crimping section being reduced is. Furthermore, there may be a risk of a shift in the width direction of the folded section during the connection can be reduced.

Furthermore, Preferably, the front ends of the crimping pieces are inclined or chamfered.

According to the invention is further a method according to claim 5 available posed.

Preferably is the crimping section allowed in the crimping step, slightly reset, so that the elastic deformation or deformation of the sheath or casing accordingly corresponding to the folded section or in the neighborhood thereof is allowed to elastically recover, the elastic Deformation of the serving not completely deleted or is canceled, so that a sufficient fastening force can be obtained.

following will be an embodiment of the invention with reference to the accompanying Drawings described.

A shielded connector 10 According to this embodiment has such a one-piece or integral construction that an inner or inner terminal 20 in an outer or external connection 40 via a dielectric element 30 is recorded, and a shielded cable 50 connected with it. In the description below, one page (right side in FIG 1 ) of the connector 10 to be connected to a mating connector, not shown, designated as a front side and an opening direction (an upward direction in FIG 1 ) of an outer crimping section 45 before being assembled is referred to as an upward direction.

The shielded cable 50 is constructed such that an insulating element 53 between an inner conductor 51 formed by, for example, bundling a plurality of strands and an outer conductor 52 is made of, for example, a braided wire and / or a metal sheath and the outer surface of the outer conductor 52 by an enclosure or sheathing 54 surrounded, for example, of vinyl (see 1 ) is manufactured or manufactured. The inner or inner conductor 51 is with the inner or inner terminal 20 connected or connectable while the outer or outer conductor 52 with the outer or outer terminal 40 connected or connectable.

The indoor connection 20 is preferably a female terminal, as shown in FIG 1 is shown, and is electrically conductive. A front part of the indoor connection 20 is a tab or spike portion 21 which is engageable with an unillustrated female terminal and a tapered surface is formed at the front end thereof. At a rear part of the indoor connection 20 is a biting or engaging projection 23 for securing the internal connection 20 by cutting or engaging the top wall of a receiving hole 31 provided when in the dielectric element 30 is used, which will be described later. Behind the biting or cutting edge 23 is an inner crimping section 24 provided on the inner conductor 51 to attach.

The dielectric element 30 is made of an insulating material such as a resin and is electrically connected to the inner and outer terminals 20 . 40 isolated. Within the dielectric element 30 is the receiving or receiving hole 31 for fixing the indoor connection 20 defined in it. In the outside connection 40 To be fixed is the upper wall of the dielectric element 30 with a locking recess 32 formed and the bottom wall thereof is with a contact portion 33 trained (see 1 ).

The outdoor connection 40 For example, it is formed by bending an electrically conductive plate, and a front part thereof is a receiving portion 41 in the form of a rectangular or rectangular tube. To the aforementioned dielectric element 30 in a certain position in the receiving section 41 To lock, a substantially elastically deformable or deformable locking portion 42 and a contact piece 49 at the upper and lower or bottom wall of the receiving portion 41 made available. contacts 43 for substantially elastically contacting an unillustrated shielded connector and locking same are provided on the left and right sidewalls. Behind the receiving section 41 are stabilizing elements 44 extending outwardly along the transverse direction of the receiving portion 41 projected, provided or provided to the shielded connector 10 to be positioned while it is inserted into an unillustrated connector housing, and to the shielded connector 10 to fix in the connector housing after insertion substantially stable. Behind the stabilizing elements 44 is an outer crimping section 45 provided on a folded section 55 of the outer conductor 52 the shielded cable 50 is set, the outer crimp section 45 at least partially coincident or overlapping with the folded portion 55 is available. Preferably, the outer crimping section 45 essentially completely in a position corresponding to the folded portion 55 corresponds, provided.

The outer crimp section 45 is preferably substantially striped with a pair of preferably mige crimping or crimping pieces 46 . 47 provided, extending from a bottom section 48 extend, as in 2 is shown. The crimp pieces 46 . 47 are gradually spaced from each other and inclined surfaces are formed at the front ends thereof. The crimp pieces 46 . 47 preferably have a length sufficient to substantially surround the shielded cables of different diameters.

Like the shielded connector 10 is assembled is described. First, the serving becomes 54 at one end of the shielded cable 50 stripped to some extent the outer conductor 52 expose, which then essentially at least partially on the enclosure 54 is folded back, creating a folded section 55 is formed (see 1 ). The following is the insulating element 53 the shielded cable 50 stripped to some extent the inner conductor 51 expose, on which the inner crimp section 24 of the indoor connection 20 then fixable or fixed.

Next, the dielectric element 30 at least partially in the receiving section 41 the outer terminal 40 used from the front. Then the contact section arrives 33 essentially in contact with the contact piece 49 and the locking portion 42 essentially slides in the locking recess 32 , whereby substantially the dielectric element 30 in a certain position in the receiving section 41 is locked. If the indoor connection 20 , which with the inner conductor 51 is connected, then in the receiving hole 31 of the dielectric element 30 is used, bites or grips the cutting or biting projection 23 in the upper wall of the receiving hole 31 one to stable the internal connection 20 to fix (see 5 ).

Then the folded section 55 on the bottom section 48 arranged the outer terminal. At this time, since the crimping pieces 46 . 47 preferably especially at their bases near the bottom section 48 spaced apart, as shown in FIG 3 shown is the folded section 55 can not be displaced in the width direction, since it is between the bases of the crimp pieces 46 . 47 is held.

Thereafter, the shielded connector 10 in the state of 3 arranged in a crimping device or holding device, not shown. The crimping or crimping pieces 46 . 47 become in substantially immediate contact with the outer surface of the folded portion 55 brought. At this time, crimping is performed such that the end of the crimping piece 47 on that of the crimping piece 46 (please refer 6 ) is arranged. Because the front ends of the crimping sections 46 are formed in inclined or bevelled surfaces, the ends of the Crimpstücke 46 . 47 in order to preferably be arranged one above the other, they are easily held in direct contact.

Here is the serving 54 deformed in compressive manner in radial directions during crimping. On the other hand, the crimping pieces become 46 . 47 preferably slightly after or at the completion of crimping as described above. In this state, the outer crimping section squeezes 45 the folded section 55 , The elastic deformation of the casing 54 passing through the outer crimp section 45 is preferably substantially deleted or abolished, there or if the Crimpstücke 46 . 47 be reset. However, since the elastic deformation is not completely extinguished, the outer conductor becomes 52 over the serving 54 in close or immediate contact with the crimp pieces 46 . 47 by an elastic force of the sheath 54 kept like this in 6 is shown. Accordingly, a sufficient electrical connection between the folded portion 55 and the crimp pieces 46 . 47 trained and constructed and a sufficient fastening force can be obtained.

So it is according to the shielded connector 10 this embodiment is not necessary to separately provide the cladding crimping portion as in the prior art because the outer crimping portion 45 provides sufficient electrical connection and fastening force. The shielded connector 10 can be made smaller by shortening its overall length.

The shielded connector 10 can preferably with shielded cables 50 different outer diameter act by the overlapping length of Crimpstücke 46 . 47 is set. Shielded cables 50 Different specifications can also be achieved through the shielded connector 10 this training be handled.

As fastening realized by the outer conductor crimping portion and the cladding crimping portion in the prior art is achieved by the single outer crimping portion 45 is realized, an operation efficiency can be remarkably improved.
