[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-5 A connector crimping fixture includes a fixture base 1, an L-shaped seat 2 fixedly installed at one top end of the fixture base 1, a drive cylinder 3 passing through and fixedly installed at the top end of the L-shaped seat 2, and a crimping connector 4 coaxially installed at the output end of the drive cylinder 3.

[0028] The tooling base 1 has a movable seat 5 slidably connected to its top. The movable seat 5 has a groove 6 in the middle of its top along its width direction. The connector 7 to be crimped is placed inside the groove 6, and a lead wire 8 is inserted into one side of the connector 7 to be crimped.

[0029] The top of the movable seat 5 is divided into two identical and symmetrically distributed positioning platforms 51 by the groove 6. Both ends of the top of one of the positioning platforms 51 are equipped with baffles 10, and the top of the positioning platform 51 is located between the two baffles 10 and a limit plate 9 can be detachably installed. The limit plate 9 and the baffles 10 work together with the groove 6 to limit the connector 7 to be crimped.

[0030] Using the above technical solution, the tooling base 1 provides a stable support foundation, and the L-shaped seat 2 accurately fixes the drive cylinder 3, ensuring that the crimping connector 4 at the output end of the drive cylinder 3 can apply crimping force in a preset direction. The movable seat 5 slides with the tooling base 1 through the guide rail structure, which can flexibly adjust the position of the connector 7 to be crimped, facilitating loading and unloading operations. The groove 6 at the top of the movable seat 5 provides initial placement space for the connector 7 to be crimped. Together with the baffle 10 and the limiting plate 9 on the positioning table 51, a multi-directional limiting structure is formed, which can effectively limit the displacement of the connector 7 to be crimped during the crimping process and avoid crimping misalignment due to connector offset. At the same time, the lead wire 8 inserted on one side of the connector 7 to be crimped can be positioned synchronously with the connector, ensuring that the corresponding position of the lead wire 8 and the connector is accurate during crimping, and finally achieving stable crimping of the connector and the lead wire 8.

[0031] The connector 7 to be crimped has a boss 71 integrally formed on the middle and both ends of the side away from the lead wire 8. The limiting plate 9 facing the connector 7 to be crimped and the two baffles 10 facing the connector 7 to be crimped are tightly fitted to the connector 7 to be crimped, and the fitting surfaces are provided with slots 11 that are adapted to the shape of the boss 71.

[0032] By adopting the above technical solution, the integrally formed boss 71 on the connector 7 to be crimped cooperates with the matching slots opened on the mating surfaces of the limiting plate 9 and the baffle 10 to form a "boss-slot" positioning structure. This structure can further enhance the tightness of the connection between the connector 7 to be crimped and the limiting plate 9 and the baffle 10. It can not only limit the horizontal translation of the connector, but also resist the radial force generated during the crimping process, prevent the connector from rotating or tilting, significantly improve the positional stability of the connector 7 to be crimped, ensure that the pressure of the crimping head 4 can be accurately applied to the crimping part of the connector, reduce crimping defects caused by positioning deviations, and improve the consistency of crimping quality.

[0033] The top two sides of the limiting plate 9 are provided with strip holes 12. The strip holes 12 extend along the width direction of the positioning table 51. The inner side of the strip holes 12 is provided with a limiting screw 13 for fixing the limiting plate 9, and the bottom end of the limiting screw 13 is screwed into the corresponding threaded groove on the positioning table 51.

[0034] Using the above technical solution, the limiting plate 9 is detachably connected to the positioning table 51 through the limiting screw 13: it can adjust the position of the strip hole 12 to adapt to connectors of different lengths, and can be replaced to adapt to different types of connectors. The operation is simple, the adaptability is strong, and the replacement cost is reduced.

[0035] Both sides of the top of the baffle 10 are fitted with fastening screws 14 for fixing the baffle 10. The top of the positioning table 51 is provided with multiple threaded positioning grooves 15 evenly spaced along the width direction of the positioning table 51, corresponding to the position of the fastening screws 14.

[0036] Using the above technical solution, the baffle 10 is detachably connected to the positioning table 51 by the fastening screw 14: the spacing can be adjusted by the optional threaded positioning groove 15 to adapt to connectors of different widths, and it can also be replaced to adapt to different types of connectors without complicated tools, and has high versatility.

[0037] A connecting seat 16 is coaxially fixed to the bottom of the output end of the drive cylinder 3, and the two ends of the crimp connector 4 are installed on the bottom surface of the connecting seat 16 by bolts.

[0038] The L-shaped seat 2 has a guide groove 17 on the side facing the connecting seat 16. The guide groove 17 extends along the extension and retraction direction of the drive cylinder 3. The end of the connecting seat 16 away from the pressure joint 4 is slidably embedded in the inner side of the guide groove 17.

[0039] Using the above technical solution, the output end of the drive cylinder 3 is connected to the crimp connector 4 through the connecting seat 16, and the crimp connector 4 is detachably connected to the connecting seat 16 by bolts. When different types of connectors need to be crimped, the appropriate crimp connector 4 can be quickly disassembled and replaced, reducing the maintenance cost and changeover time of the tooling. At the same time, the guide groove on the side of the L-shaped seat 2 can provide precise guidance for the lifting and lowering movement of the connecting seat 16, preventing the output end of the drive cylinder 3 from shifting due to pressure, thus improving the stability and reliability of the crimping process.

[0040] The L-shaped seat 2 has a U-shaped protective cover 18 that can be detachably installed on the side with guide groove 17. The U-shaped protective cover 18 covers the outside of the connecting seat 16.

[0041] The U-shaped protective cover 18 is made of transparent plastic material. Both sides of the U-shaped protective cover 18 are integrally formed with folded edges 19, which are detachably fixed to the side of the L-shaped seat 2 by screws.

[0042] Using the above technical solution, the U-shaped protective cover 18 covers the outside of the connector 16. The transparent material makes it easy to observe the pressing and the movement of the connector 16, and can prevent operators from accidentally touching the moving parts. Furthermore, the folded edge 19 and screws enable detachable installation, making disassembly and assembly convenient and facilitating subsequent maintenance.

[0043] A strip guide rail 20 is fixedly installed at the top center of the tooling base 1 along its width direction by countersunk screws. A slot adapted to the cross-sectional shape of the strip guide rail 20 is opened at the bottom center of the movable seat 5, and the movable seat 5 slides with the strip guide rail 20 through the slot.

[0044] By adopting the above technical solution, the countersunk screw installation method can avoid the screw tip protruding and affecting the sliding of the movable seat 5, ensuring that the movable seat 5 can move smoothly along the strip guide 20; the strip guide 20 is set along the width direction of the tooling base 1, providing precise sliding guidance for the movable seat 5, so that when the movable seat 5 drives the connector 7 to be crimped, it can be precisely aligned with the bottom of the crimping head 4, avoiding crimping misalignment caused by the offset of the movable seat 5.

[0045] Working principle:

[0046] The connector 7 and lead wire 8 to be crimped are placed in the groove 6 of the movable seat 5. The limiting plate 9 on the positioning table 51 cooperates with the baffles 10 on both sides to form a bidirectional limiting from the end and side of the connector, firmly fixing the position of the connector 7 to be crimped and preventing it from shifting or shaking during subsequent sliding and crimping. The movable seat 5 is pushed to slide along the strip guide rail 20 of the tooling base 1 so that the connector is accurately aligned with the crimping head 4 below the drive cylinder 3 on the L-shaped seat 2. The drive cylinder 3 drives the crimping head 4 to move downward to complete the crimping of the connector and lead wire 8. During this process, the connecting seat 16 slides along the guide groove 17 to ensure accurate crimping.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
