[0002] In the manufacturing process of automotive wiring harnesses, the assembly of wiring harness terminals and wiring harnesses is a key link to ensure the reliability of electrical connections. Wiring harness terminals are usually used to integrate and fix multiple wires to achieve the transmission of electrical signals or power.

[0003] Usually, the wire is plugged into the terminal by holding it, but this method easily causes the wire to be twisted or irregular. In addition, after the wire and the terminal are fully assembled, a sheath needs to be installed. The purpose of the sheath is not only to protect the terminal, but also to lock the wire assembled in the terminal by squeezing the locking part inside the terminal through the snap-fit ​​between the sheath and the terminal. After the wire and the terminal are installed, the assembly of the sheath and the terminal is inconvenient to operate, mainly due to the protrusion of the wire, which makes the sheath and the terminal have no force point for the fitting and squeezing.

[0004] The existing tooling can only guide the wire assembly, that is, the terminal is connected to the harness guide in the tooling, and the wire inserted through the terminal is used with the harness guide to prevent the wire from twisting. However, this type of tooling still cannot solve the secondary locking problem between the sheath and the terminal, that is, the terminal after installation mentioned above has no compression force point due to the obstruction of the wire, which makes it inconvenient to assemble the sheath with the terminal. Utility Model Content

[0008] The docking seat includes a wiring harness docking joint and a protective cover, and the wiring harness docking joint is inserted from bottom to top and fits in the protective cover; the docking seat slides down along the assembly opening so that the bottom of the wiring harness docking joint corresponds to the lifting platform, and elastic clips are provided on both sides of the top of the mold base to limit the top of the protective cover.

[0009] Furthermore, a plurality of flat-head polished rods penetrating and sliding on the lifting platform are provided at the bottom of the assembly opening, and the flat ends of the flat-head polished rods are provided with springs abutting against the lifting platform.

[0010] Furthermore, a wire harness guiding platform is provided on the top of the lifting platform, and a guiding hole corresponding to the wire harness hole in the wire harness butt joint is provided in the wire harness guiding platform.

[0011] Furthermore, openings are provided on both sides of the top of the mold base, and elastic clips are adapted to be installed in the openings.

[0012] Furthermore, the mold base is composed of an upper module and a lower module, wherein the assembly opening extends from the upper module to the lower module.

[0013] Furthermore, a movable opening communicating with the bottom of the assembly opening is provided at the bottom of the lower module, wherein the tilting rod is adapted to the movable opening and its hinge point is located in the movable opening.

[0014] Furthermore, the upper and lower modules are matched by threaded fastening of fixing screws.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-3 , a harness docking interface pre-assembly tooling, comprising a mold base 100 and a docking base 200; the mold base 100 has an assembly opening 110 inside, and a lifting platform 120 is provided in the assembly opening 110, and the lifting platform 120 moves up along the assembly opening 110 through the action of a tilting rod 130 hinged to the bottom of the assembly opening 110;

[0024] The docking seat 200 includes a wiring harness docking connector 210 and a protective cover 220. The wiring harness docking connector 210 is inserted from bottom to top and fits in the protective cover 220. The docking seat 200 slides down along the assembly opening 110 so that the bottom of the wiring harness docking connector 210 corresponds to the lifting platform 120, and elastic clips 140 are provided on both sides of the top of the mold base 100 to limit the top of the protective cover 220.

[0025] The mold base 100, as the basic part of the tooling, provides a stable platform for the assembly process. The assembly port 110 is located inside the mold base, and is the area where the wire harness butt joint 210 and the lifting platform 120 interact. The lifting platform 120 is arranged in the assembly port 110, and its function is to move upward under the push of the tilting rod 130 to lift the wire harness butt joint 120, and help complete the secondary locking of the wire harness butt joint 210 and the protective cover 220. The tilting rod 130 is hinged at the bottom of the assembly port 110, and through its action, it drives the lifting platform 120 to move upward along the assembly port, and is a key mechanical component for realizing the lifting action. The docking seat 200 includes a wire harness butt joint 210 and a protective cover 220, which are used to fix and guide the wire harness butt joint 210 to be correctly inserted into the protective cover 220. The wire harness butt joint 210 is designed to cooperate with the wires and be inserted into the protective cover 220, and is a key component for realizing electrical connection. The protective cover 220 is used to cover and protect the assembled wire harness connector 210, and cooperate with the wire harness connector 210 to achieve secondary locking. The elastic clamps 140 are arranged on both sides of the top of the mold base 100 to limit the top of the protective cover 220 to ensure its accurate positioning during the assembly process, and provide necessary limit during the lifting process to prevent the protective cover 220 from moving up.

[0026] The harness connector 210 is first inserted into the protective cover 220 from bottom to top to form a preliminary fit. The docking seat 200 then slides down along the assembly opening 110 so that the bottom of the harness connector 210 is aligned with the lifting platform 120. After the assembly of the wires and the harness connector 210 is completed, the lifting platform 120 moves up along the assembly opening 110 through the action of the tilting rod 130, lifts the harness connector 210, and causes the terminal to be squeezed into the cover 220. The elastic clip 140 limits the top of the protective cover 220 to ensure that the terminal can be tightly fitted with the cover and locked for a second time during the lifting process. By moving the lifting platform 120 upward, the locking piece inside the terminal is squeezed, so that the wire assembled in the terminal is locked in the terminal, completing the entire assembly and locking process.

[0027] like Figure 3 As shown, the elastic clamp 140 includes a rectangular block 141, an insert block 142 and a limit block 143:

[0028] An L-shaped sliding opening 141d is provided inside the rectangular block 141, and the insert block 142 slides along the long side of the L-shaped sliding opening 141d. A top block 142a is provided on one side of the bottom of the insert block 142, and the top block 142a slides along the short side of the L-shaped sliding opening 141d. A first spring 142c is abutted on the top block 142a, and a baffle 141a abutting against the other side of the first spring 142c is provided on the short side of the L-shaped sliding opening 141d, which is used for resetting the insert block 142 after sliding.

[0029] In addition, a sliding hole 141b communicating with the long side of the L-shaped sliding opening 141d is provided on the top of the rectangular block 141, and the limiting block 143 slides up and down along the sliding hole 141b; a U-shaped block 143a is fixed to the bottom of the limiting block 143, and a U-shaped groove 141c communicating with the long side of the L-shaped sliding opening 141d is provided on the bottom of the rectangular block 141, and the U-shaped block 143a slides up and down along the U-shaped groove 141c; the side of the U-shaped block 143a protrudes from the side of the limiting block 143, and the protruding side of the U-shaped block 143a can be limited to the bottom of the insert block 142, limiting the continuous rise of the limiting block 143; the bottom of the U-shaped block 143a is abutted with a second spring 143b, and the bottom of the second spring 143b abuts against the bottom of the U-shaped groove 141c, and the elastic pressure of the second spring 143b makes the U-shaped block 143a slide in the U-shaped groove 141c.

[0030] In addition, a U-shaped opening 142 b is formed in the inserting block 142 corresponding to the U-shaped groove 141 c , and the U-shaped block 143 a fits in the U-shaped opening 142 b and slides along the inner side thereof.

[0031] Specific locking process: In the initial situation, the plug block 142 slides through the L-shaped sliding opening 141d of the rectangular block 141, and the top block 142a at the bottom of the plug block 142 contacts the first spring 142c, that is, the first spring 142c is in a state of uncompressed and unstretched; at this time, the U-shaped opening 142b on the plug block 142 is surrounded by the outer lower half of the limit block 143, and the upper half of the limit block 143 slides through the sliding hole 141b, and the protruding side of the U-shaped block 143a at the bottom of the limit block 143 abuts against the bottom of the plug block 142, and the second spring 143b is limited by the bottom of the limit block 143 by the U-shaped block 143a and is in a compressed state.

[0032] When in use, the insert block 142 is pressed to slide along the L-shaped sliding opening 141d toward the direction of the first spring 142c. During the sliding process, the insert block 142 is pressed through the top block 142a to squeeze the first spring 142c to store force, and the insert block 142 is pressed to make the U-shaped opening 142b move synchronously by sliding. When the U-shaped opening 142b slides to correspond to the U-shaped block 143a, the U-shaped block 143a is rebounded by the stored force of the second spring 143b and moves upward to fit in the U-shaped opening 142b, so that the insert block 142 is limited by the U-shaped block 143a through the U-shaped opening 142b and remains in the position after sliding. If the insert block 142 is to cancel the plug-in limit of the protective cover 220, on the contrary, the limit block 143 is pressed to push the U-shaped block 143a down to the bottom of the insert block 142, and the insert block 142 is reset by the rebound of the first spring 142c.

[0033] In some embodiments, a plurality of flat-head polished rods 121 penetrating and sliding on the lifting platform 120 are disposed at the bottom of the assembly opening 110 , and springs 122 abutting against the lifting platform 120 are disposed at the flat ends of the flat-head polished rods 121 .

[0034] A plurality of flat polished rods 121 are provided at the bottom of the assembly opening 110. These polished rods are part of the mechanical structure and are used to support and guide the movement of the lifting platform 120. The flat polished rods 121 are designed to penetrate and slide along the lifting platform 120, which allows the lifting platform to maintain smooth and precise movement when moving up or down. The flat ends of the flat polished rods 121 are provided with springs 122, which provide the necessary elastic force for the movement of the lifting platform and ensure that the lifting platform can be smoothly pushed and reset.

[0035] When the harness butt joint 210 needs to be assembled, the lifting platform 120 is located at the initial position of the assembly port 110, the flat-top polished rod 121 is located below the lifting platform, and the spring 122 is in an uncompressed state. As the docking seat 200 slides down along the assembly port 110, the harness butt joint 210 gradually abuts against the lifting platform 120, and the lifting platform 120 begins to move down along the flat-top polished rod 121, and the spring 122 at the flat end of the flat-top polished rod 121 is stretched to store energy. This stretching action provides power for the lifting platform to rise, helping the lifting platform to smoothly push the harness butt joint 210 to move upward and achieve cooperation with the protective cover 220. After the elastic clip 140 locks the protective cover 220 on the harness butt joint 210, the lifting of the tilting rod 130 allows the lifting platform 120 to move up along the flat-top polished rod 121 and ensures that the spring 122 releases energy. This design ensures that the lifting platform 120 can be raised and lowered smoothly and controllably. Meanwhile, the spring 122 provides a buffering effect, thereby reducing the impact or damage that may be caused to the wiring harness connector 210 or the protective cover 220 during the assembly process.

[0036] In some embodiments, a wire harness guiding platform 123 is disposed on the top of the lifting platform 120 , and a guiding hole 123 a corresponding to the wire harness hole in the wire harness docking connector 210 is opened in the wire harness guiding platform 123 .

[0037] The top of the lifting platform 120 is specially designed with a wire harness guide platform 123, which is a component for guiding the wire harness to correctly enter the wire harness butt joint 210. The wire harness guide platform 123 is provided with guide holes 123a, which correspond to the size and shape of the wire harness holes in the wire harness butt joint 210, ensuring that the wire harness can pass through and be inserted into the wire harness butt joint 210 accurately.

[0038] In some embodiments, openings 101 are provided on both sides of the top of the mold base 100 , and the elastic clamps 140 are adapted to be installed in the openings 101 .

[0039] Specific openings 101 are designed on both sides of the top of the mold base 100, which serve as the installation positions of the elastic clamps 140, allowing the elastic clamps to cooperate with the main structure of the mold base 100. After the elastic clamps 140 are installed, their elastic properties enable them to exert a constant force on the protective cover 220, which helps to keep the position of the protective cover stable during the assembly process and provide necessary resistance when the lifting platform 120 moves up. After the assembly of the wiring harness connector 210 and the protective cover 220 is completed, the elastic clamps 140 can be released to allow the docking seat 200 to be removed from the assembly port 110, completing the entire assembly process.

[0040] In some embodiments, the mold base 100 is composed of an upper module and a lower module, wherein the assembly port 110 extends from the upper module to the lower module, and the upper and lower modules are mated by threaded fastening of the fixing screws 102 .

[0041] The mold base 100 adopts a modular design, consisting of an upper module and a lower module. This design allows each part of the mold base to be independently manufactured and maintained. The assembly port 110 is a key part of the mold base 100, which extends from the upper module to the lower module to form a channel for assembling the wire harness connector 210 and the protective cover 220.

[0042] The upper module and the lower module of the mold base 100 are combined together by fixing screws 102 or other fastening methods, and the assembly opening 110 runs through the two modules to provide accurate positioning for the assembly of the wire harness assembly. By designing the assembly opening 110 to extend from the upper module to the lower module, the internal space of the mold base is fully utilized, providing necessary space for the insertion of the wire harness joint 210 and the movement of the lifting platform 120.

[0043] In some embodiments, a movable opening 103 communicating with the bottom of the assembly opening 110 is formed at the bottom of the lower module, wherein the tilting rod 130 is adapted to the movable opening 103 and its hinge point is located in the movable opening 103 .

[0044] The bottom of the lower module is specially designed with a movable opening 103, which is connected to the bottom of the assembly opening 110, providing the necessary space and path for the movement of the tilting rod 130. The tilting rod 130 is adapted in the movable opening 103, and its hinge point is located in the movable opening 103, which allows the tilting rod to rotate in the movable opening. The hinge point of the tilting rod 130 is the point where it is connected to the movable opening 103. This design enables the tilting rod to rotate around the hinge point, thereby pushing the lifting platform 120 to rise or fall.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
