This embodiment has described car wiring harness wire conductor, as shown in fig. 1 to 5, including encapsulation piece 4 and two protective sheaths 5 that many heart yearns 12, two insulating materials made, the both ends of every heart yearn 12 are naked copper line 13 to the naked copper line 13 at both ends is fixed respectively one in encapsulation piece 4, the many naked copper lines 13 that are located same encapsulation piece 4 department are the straight line and follow the length direction of encapsulation piece 4 arranges, and every naked copper line 13 at least part is worn out encapsulation piece 4 and wear out the partial coating and have tin layer 2 to constitute a sclerosis and be cylindrical PIN foot 3, have the jack 52 that sets up corresponding to each PIN foot 3 on every protective sheath 5 respectively, PIN foot 3 is inserted and is established in the jack 52.

In the present embodiment, a signal transmission harness with an outer cover 11 is used, which may generally include an outer cover 11 and four cores 12 enclosed in the outer cover 11. When carrying out the production of the car wiring harness wire rod conductor of this embodiment, at first peel the quilt 11 at pencil both ends, about 2cm, expose four inside heart yearns 12, then peel the crust with the both ends of heart yearn 12 again, the bare copper 13 of about 8mm is exposed, then to the injection molding machine encapsulation formation of moulding plastics encapsulation piece 4, encapsulation piece 4 encapsulates 5 mm's bare copper 13 and 3 mm's 12 tip of heart yearn together and fixes wherein, lets 3 mm's bare copper 13 wear out encapsulation piece 4, carries out the tin-plating to the slow bare copper 13 of 3 that wear out at last, and shaping goes out tin layer 2 on the bare copper 13 copper line of wearing out so can obtain PIN foot 3.

Therefore, the automobile wire harness conductor of the embodiment has good overall consistency, the traditional connection terminal is omitted, the structure of the wire joint is more compact, and production cost can be saved while installation and arrangement are facilitated. In addition, since it is not necessary to consider the reliability of the connection between the core wire 12 and the connection terminal, the maintenance is facilitated.

Encapsulation piece 4 is for being made by the plastic material, wholly is the cuboid form, heart yearn 12 is along encapsulation piece 4's direction of height passes encapsulation piece 4, by one side of encapsulation piece 4 gets into and wears out from the side of relative opposite side, and what wear out from the opposite side is bare copper 13 line, encapsulation piece 4 encapsulates fixed part heart yearn 12 and wraps up partial heart yearn 12 simultaneously.

Correspondingly, protective sheath 5 is the cuboid form equally, and protective sheath 5's middle part have adapt to encapsulation piece 4 sink the cavity be provided with locating piece 51 in the cavity that sinks, locating piece 51 has a plurality ofly jack 52.

Further, the height of the positioning block 51 is not less than the length of the PIN leg 3. The height of protecting bush 5 is about 8mm in this embodiment, its length width that sinks the cavity all with encapsulation piece 4 is the same, and inside sinks to form locating piece 51 highly is 4mm, therefore can wrap up PIN foot 3 completely and protect, and sink the structure of cavity can simultaneously with encapsulation piece 4 clearance fit protects encapsulation piece 4.

In order to improve the insertion and extraction force, the package block 4 is provided with pins 41 along two sides of the length direction, and two slots 53 are correspondingly arranged in the sinking cavity of the protection sleeve 5, and the two slots 53 are arranged on two opposite inner side walls of the sinking cavity. The package block 4 department has installed participate in 41 additional, can improve the plug power, and the accident that just also can prevent when the car wiring harness butt joint equipment drops, improves and connects the reliability.

In consideration of the foolproof design, in the embodiment, as shown in fig. 3 and 5, the PINs 41 and the PIN legs 3 are arranged on the same straight line, and the connecting line L1 between the PINs 41 and the PIN legs 3 is staggered with the symmetrical center line L2 of the exit face of the PIN legs 3, and is not overlapped, that is, the PIN legs 3 are not arranged on the center line L2 of the exit face of the PIN legs 3. That is to say, encapsulation piece 4 can only insert in protective sheath 5 with fixed position, when being convenient for take, also can realize preventing slow-witted protection when inserting equipment, prevents the wrong insertion when improving grafting efficiency, improves the security.

The above embodiments are merely illustrative of the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the content of the present invention and implement the utility model, and not to limit the scope of the utility model, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the scope of the present invention.
