Specific embodiment

It please refers to shown in Fig. 1 to Fig. 9, that show the specific structure of the preferred embodiments of the invention, the data line Manufacture craft includes following steps:

Step 1 takes a cable 10, and does peeling processing to the front end of cable 10, makes the multiple conducting wires unit 11 in cable 10 The front end of front end stretching cable 10；Each lead unit 11 includes at least two cores 111 and is coated at least two core wires 111 Outer aluminium foil layer 112；

Step 2 takes a clamp group 20, and clamp group 20 includes the rear end wire clamp 21 and front end wire clamp 22 that front and back fits together, after The upper and lower surface of end terminal 21 is recessed with multiple the first separated time slots 201 being intervally arranged, and the first separated time slot 201 runs through rear end The front and back sides of wire clamp 21；The upper and lower surface of front end wire clamp 22 is recessed with multiple the second separated time slots 202 being intervally arranged, and Equinoctial line slot 202 runs through the front and back sides of front end wire clamp 22, multiple second separated time slots 202 and corresponding first separated time slot, 201 phase Connection；

112 front end of aluminium foil layer on each lead unit 11 is removed one section, convenient for the core in lead unit 11 by step 3 111 front ends separate, and stretch out the front end of core 111 outside aluminium foil layer 112, and by 111 front end of core on each lead unit 11 It separates, then the front end of more cores 111 is passed through into corresponding first separated time slot 201 and is caught in corresponding second separated time slot 202, To separate core wire 111, the first mould group is formed.And the front end of core 111 is stuck in the second separated time slot 202 here And the front end of the second separated time slot 202 is not extended out；

First mould group is put into the first molding die, and mold first between cable 10 and rear end wire clamp 21 by step 4 Internal model 30, and be embedded in the rear end of lead unit 11 in first internal model 30；

Step 5 makes more cores from taking out product in the first molding die and removing front end wire clamp 22 from rear end wire clamp 21 The front end of rear end wire clamp 21 is stretched out in the front end of line 111；

Step 6 does peeling processing to the front end of more core wires 111, and 101 front end of metallic conductor in core wire 111 is made to stretch out core wire 111 front end；

Step 7 takes a connector 40, and more metallic conductors 101 are welded on the correspondence pad on connector 40, and connects The front end face of the rear end face of device 40 and rear end wire clamp 21 closely, forms the second mould group；

Second mould group is put into the second molding die by step 8, molds the second internal model 50, and the second internal model 50 wraps more Metallic conductor 101；

Step 9 is taken out product, and the fit on metal shell 60 in the back end outer surface of product from the second molding die, is added Work is completed.

In above-mentioned procedure of processing, rear end wire clamp 21 and front end wire clamp 22 are assembled in together first, in molding first When internal model 30, the composite structure of rear end wire clamp 21 and front end wire clamp 22 ensure that intensity when sealing, and on front end wire clamp 22 Second separated time slot 202 plays the role of fixed 111 front end of core wire.And the strip length of the aluminium foil layer 112 in lead unit 11 is The thickness of clamp group 20, and the strip length of traditional aluminium foil layer is that the thickness of wire clamp adds the core wire length for stretching out wire clamp front end, institute It is less with the removing of aluminium foil layer 112 in the present invention, it is more steady and good from the high frequency characteristics impedance that can guarantee in this product Anti- cross-talk effect, to improve the high frequency characteristics of product.And front end wire clamp 22 is reusable, has saved cost and resource.

The front end face middle position of above-mentioned rear end wire clamp 21 is convexly equipped with inserting column 211, corresponding, the rear end face of front end wire clamp 22 Be recessed with the first slot 221 and the second slot 401 on the rear end face of connector 40 respectively, inserting column 211 is inserted into the first slot 221 Fixed or inserting column 211 is inserted into fixed in the second slot 401；Before step 5, inserting column 211 is cooperated with the first slot 221 Fixed, in step 7, inserting column 211 is to cooperate fixation in the second slot 401 of insertion.

It is convexly equipped with multiple fins 212 on the rear end face of rear end wire clamp 21, and forms molding position between adjacent two fin 212, The front end of above-mentioned first internal model 30 is integrally formed and is connected on multiple fins 212, forms the design of position, makes rear end wire clamp 21 and the The connection of one internal model 40 is more firm.It is laterally convexly equipped with ribs 213 on the rear end face of the rear end wire clamp 21, the ribs 213 It is connected on multiple fins 212.

The multiple first separated time slots 201 and underlying multiple first separated time slots 201 being located above are in upper and lower dislocation type Arrangement, corresponding, the multiple second separated time slots 202 and underlying multiple second separated time slots 202 being located above are in wrong up and down The structural strength of rear end wire clamp 21 and front end wire clamp 22 can be effectively ensured in position formula arrangement, the design of this class formation.Described first point The aperture of wire casing 201 is greater than the aperture of the second separated time slot 202, and the aperture of the second separated time slot 202 and the outer diameter of core wire 111 are mutually fitted Match, i.e., core wire 111 is stuck in the second separated time slot 202.

Design focal point of the invention is: passing through the rear end wire clamp fitted together before and after being designed to clamp group and front end Wire clamp, then the aluminium foil layer removing outside core wire is a bit of, then the front end of core wire is stuck in the wire clamp of front end and the front end of core wire And do not extend out the front end face of front end of line folder, after having formed the first internal model, front end of line is clamped down, keeps the front end of core wire exposed The front end face of rear end wire clamp, and solder connector is removed the peel to the front end of core wire, so above-mentioned to aluminium foil layer front end strip length etc. In or less than clamp group thickness, compare traditional aluminium foil layer front end strip length reduce it is very much, so that product be enable to obtain Stable high frequency characteristics impedance, while avoiding cross-talk when signal transmission.

The above described is only a preferred embodiment of the present invention, be not intended to limit the scope of the present invention, Therefore any subtle modifications, equivalent variations and modifications to the above embodiments according to the technical essence of the invention, still Belong in the range of technical solution of the present invention.
