[0031] In order to facilitate those skilled in the art to understand, the structure of the present application will be further described in detail in combination with the drawings:

[0032] Reference Figures 1-6 A wire harness connector press-fit jig:

[0033] The wire harness connector includes a first connector and a second connector, the first connector and the second connector each include a terminal 7 with a groove on an outer wall, and a clamping sleeve 8 clamped on the outer side of the terminal 7, and the first connector further includes a plurality of pins 6 inserted into a plurality of insertion slots 73 on the terminal 7.

[0034] The press-fit jig includes:

[0035] A base 1 with a recessed top forming a receiving groove 11;

[0036] A positioning member 2 including a positioning sleeve 21 located in the receiving groove 11, and a plurality of convex ridges 211 protruding from the inner wall of the positioning sleeve 21 and adapted to the groove; the positioning sleeve 21 is used for limiting the sleeve of the terminal 7;

[0037] A plurality of limiting blocks 3 movably arranged in the receiving groove 11 and locked or unlocked by a locking member; a plurality of limiting blocks 3 are used for clamping on the outer side of the clamping sleeve 8 after the clamping sleeve 8 is sleeved on the outer side of the terminal 7.

[0038] The pressing seat is driven by the driving device to move up and down, and is used to press the sleeve 8 clamped by the plurality of limiting blocks 3 to the outer side of the terminal 7.

[0039] The top block 5 is provided with a plurality of insertion holes 51 adapted to the plurality of insertion pins 6. The pressing seat is also used to press the top block 5 after the plurality of insertion pins 6 are inserted into the plurality of insertion holes 51 and insertion slots 73 at both ends, respectively, so as to press the plurality of insertion pins 6 into the plurality of insertion slots 73.

[0040] The above structure is used to assemble the first joint. The terminal 7 is limited by the positioning sleeve 21 to form circumferential limitation, and then the sleeve 8 is sleeved to the outer side of the terminal 7. The sleeve 8 is locked and clamped to the outer side of the sleeve 8 by the limiting block 3 to form horizontal and vertical limitation. Then the sleeve 8 clamped by the plurality of limiting blocks 3 is pressed by the pressing seat to the outer side of the terminal 7 to complete the clamping and sleeving between the sleeve 8 and the terminal 7. The insertion holes 51 and the insertion slots 73 are matched to limit the upper and lower ends of the insertion pin 6 by the additional top block 5. Finally, the plurality of insertion pins 6 are stably inserted into the plurality of insertion slots 73 by pressing the top block 5 by the pressing seat. When assembling the second joint, the terminal 7 is limited by the positioning sleeve 21 to form circumferential limitation, and then the sleeve 8 is sleeved to the outer side of the terminal 7. The sleeve 8 is locked and clamped to the outer side of the sleeve 8 by the limiting block 3 to form horizontal and vertical limitation. Then the sleeve 8 clamped by the plurality of limiting blocks 3 is pressed by the pressing seat to the outer side of the terminal 7 to complete the clamping and sleeving between the sleeve 8 and the terminal 7. Thus, the terminal 7 and the sleeve 8, and the insertion pin 6 and the terminal 7 are quickly positioned and assembled, which meets the demand of quickly assembling a small number of wire harness joint samples for electrical test. The sleeve 8 and the insertion pin 6 are prevented from being skewed, and the accuracy of the electrical test of the assembled wire harness joint sample is improved.

[0041] In order to improve the adaptability of the pressing tool, the bottom of the base 1 is recessed to form a mounting groove 12. The lower part of the positioning member 2 is a limiting part 22 which is detachably embedded in the mounting groove 12, and the upper part is the positioning sleeve 21 which has an outer diameter smaller than the limiting part 22 and penetrates through the groove bottom of the containing groove 11 into the containing groove 11. Thus, the detachable connection between the positioning member 2 and the base 1 is realized by the cooperation between the limiting part 22 and the mounting groove 12. When facing different models of terminals 7, the corresponding positioning member 2 can be replaced, and the limiting part 22 of the installed positioning member 2 is limited in the mounting groove 12, which prevents the positioning member 2 from moving up and down and circumferentially. Under the premise of improving the adaptability of the pressing tool, the stability of the circumferential limitation of the positioning member 2 to the terminal 7 is ensured.

[0042] In order to facilitate the disassembly of the positioning piece 2, the four corners of the mounting groove 12 are outwardly expanded to form a corresponding accommodation groove 121 corresponding to the four corners of the limiting portion 22. Thus, by adding the accommodation groove 121, the fingers can be inserted into the positioning piece 2 to take out or install it, without affecting the circumferential limiting effect of the mounting groove 12 on the limiting portion 22, thereby improving the convenience of disassembling the positioning piece 2, and avoiding the situation that the limiting portion 22 is difficult to take out after the pressing assembly is completed.

[0043] In order to improve the stability of the clamping of the limiting block 3, the number of the limiting block 3 is two and is vertically arranged on both sides of the accommodating groove 11, the four corners of the limiting block 3 are screw-connected with limiting screws 31, the distal ends of the limiting screws 31 on both sides are respectively limited to slide through the two side walls of the accommodating groove 11, the outer wall of the sleeve 8 is provided with a flat surface 81, and the opposite sides of the two limiting blocks 3 are provided with clamping limiting surfaces 32 corresponding to the two flat surfaces 81. Thus, by limiting the sliding connection between the limiting screws 31 arranged at the four corners and the two side walls of the accommodating groove 11, the stability of the two limiting blocks 3 clamping towards each other can be improved, and the two limiting blocks 3 can always be kept vertical, thereby ensuring the limiting stability of the two limiting blocks 3 after being locked and clamped to the two flat surfaces 81 on the outside of the sleeve 8 through the two clamping limiting surfaces 32, and ensuring that the sleeve 8 is always in a vertical state without tilting, thereby improving the stability and accuracy of the pressing seat pressing the sleeve 8 to the outside of the terminal 7.

[0044] In order to improve the stability of the locking piece, the locking piece includes a plurality of locking screws 4 screwing through the two side walls of the accommodating groove 11 and the ends abutting against the two limiting blocks 3. Thus, by adjusting the depth of the locking screw 4 screwing through the two side walls of the accommodating groove 11, the clamping distance of the two limiting blocks 3 towards each other can be adjusted, so that the two limiting blocks 3 can be adaptively clamped on both sides of the sleeve 8 of different specifications, further improving the adaptability of the pressing tool.

[0045] In order to further improve the stability of the pressing assembly between the pin 6 and the terminal 7, the upper ends of a plurality of the pins 6 are contracted to form connection ends 61, the bottom middle part of the top block 5 is recessed to form a limiting groove 52, and a plurality of the insertion holes 51 are arranged through the groove bottom of the limiting groove 52 and have an inner diameter and a length matched with those of the connection end 61. Thus, by arranging a plurality of limiting grooves 52, a plurality of the pins 6 can be first limited and inserted into the limiting grooves 52, and a plurality of the connection ends 61 can be inserted into a plurality of the insertion holes 51, and then the lower ends of a plurality of the pins 6 can be inserted into a plurality of the insertion grooves 73 of the terminal 7, thereby improving the contact area between the top block 5 and the upper ends of a plurality of the pins 6, and further improving the stability of the top block 5 pressing a plurality of the pins 6 to be inserted into a plurality of the insertion grooves 73 when the pressing seat presses the top block 5, and reducing the risk of the top pin being broken during the pressing process.

[0046] Specifically, the outer side of the terminal 7 is concave and provided with a clamping area 71, the upper end is concave and provided with a clamping groove 72 with a groove bottom corresponding to the clamping area 71, the inner wall of the sleeve 8 is convex and provided with a clamping ring 82 corresponding to the clamping area 71 and a clamping end 83 corresponding to the groove bottom of the clamping groove 72; after the sleeve 8 is clamped to the outer side of the terminal 7, the clamping ring 82 is clamped into the clamping area 71 and the clamping end 83 is clamped to the groove bottom of the clamping groove 72.
