Description

Technical Field

[0001] This utility model belongs to the field of crimping fixture technology, specifically a crimping fixture for piercing connectors. Background Technology

[0002] A piercing connector involves placing the wire above the cut and applying uniform vertical force to push the wire into the cut. The wire insulation is pierced and enters the clamp, establishing conductivity between the conductor and the connector. This enables rapid and efficient wire connection. The piercing connector connection process typically requires a crimping fixture for assistance. Existing crimping fixtures use limit seats to limit the crimping depth, but they cannot fine-tune the crimping depth. This can lead to incomplete crimping, resulting in poor electrical connection stability, or excessive crimping, causing damage to the metal conductor. Therefore, this application proposes a piercing connector crimping fixture. Utility Model Content

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 5 The present invention discloses a crimping fixture for a piercing connector, comprising a support base 1, an L-shaped support frame 2 fixedly mounted on one end of the support base 1, a controller 3 fixedly mounted on one side of the L-shaped support frame 2, a control button 4 mounted on the controller 3, a lower positioning block 5 mounted at the middle position of the top of the support base 1, a cylinder 6 fixedly mounted on the L-shaped support frame 2, an upper positioning block 7 mounted at the bottom of the cylinder 6, a limit component 8 mounted between the upper positioning block 7 and the lower positioning block 5, and a piercing connector 9 located between the upper positioning block 7 and the lower positioning block 5.

[0023] In use, place the piercing connector 9 on the top of the lower positioning block 5, insert the wire into the inside of the piercing connector 9, and the cylinder 6 drives the upper positioning block 7 to press down. The upper positioning block 7 and the lower positioning block 5 are used to press the piercing connector 9 together, thus achieving the crimping of the piercing connector 9 and the wire.

[0024] The top of the lower positioning block 5 is provided with a lower positioning slot 10 and a receiving slot 11 that match the piercing connector 9. The sides of both ends of the top of the lower positioning block 5 are provided with limiting slide grooves 12. An adjustable positioning seat 13 is slidably arranged inside the limiting slide groove 12. The adjustable positioning seat 13 is composed of a slide 14 and a stepped positioning support platform 15. The slide 14 is slidably connected to the inside of the limiting slide groove 12, and the stepped positioning support platform 15 is fixedly connected to the top of the slide 14. The bottom of the upper positioning block 7 is provided with an upper positioning slot 16 that matches the lower positioning slot 10 and the piercing connector 9. The width of the lower positioning slot 10 is greater than the width of the upper positioning slot 16.

[0025] The lower positioning slot 10 and the upper positioning slot 16 can limit the piercing connector 9. During the crimping process, the position of the adjustable positioning seat 13 can be adjusted according to the actual crimping effect. The stepped positioning support platform 15 can achieve different height limits, thereby limiting the downward pressing height of the upper positioning block 7, thus avoiding the crimping quality from being affected by the crimping depth being too small or too large.

[0026] Both ends of the front and back of the lower positioning block 5 are provided with limiting locking bolts 17 that match the adjustable positioning seat 13. The limiting locking bolts 17 are threadedly connected to the lower positioning block 5. The adjustable positioning seat 13 can be locked and limited by the limiting locking bolts 17 to improve stability.

[0027] The limiting assembly 8 consists of a limiting rod 18, a limiting top plate 19, and a spring 20. The limiting rod 18 is fixedly connected to both ends of the top of the lower positioning block 5. The limiting rod 18 slides through the upper positioning block 7. The limiting top plate 19 is located at the top of the upper positioning block 7 and is fixedly connected to the limiting rod 18. The spring 20 is located between the lower positioning block 5 and the upper positioning block 7 and is sleeved on the limiting rod 18.

[0028] The limiting rod 18, the limiting top plate 19, and the spring 20 can vertically limit the upper positioning block 7 and the lower positioning block 5 to prevent misalignment.

[0029] The piercing connector 9 consists of a connector base 21, a connector cover 1 22, a connector cover 23, and two piercing metal plates 24. The connector cover 1 22 and the connector cover 23 are respectively connected to the two sides of the connector base 21, and the piercing metal plates 24 are fixedly connected to the inside of the connector base 21.

[0030] During crimping, connector cover 1 22 and connector cover 23 are crimped separately. Connector base 21 can overlap with lower positioning slot 10 to form a limit. Connector cover 1 22 and connector cover 23 can match lower positioning slot 10 and receiving slot 11. Piercing metal plate 24 can penetrate wire insulation layer and contact conductor.

[0031] In operation, the system comprises a lower positioning block, a cylinder, an upper positioning block, a lower positioning slot, a receiving slot, and an upper positioning slot. This allows for the positioning of the piercing connector and the crimping connection between the connector and the wire. An adjustable positioning seat, consisting of a slide and a stepped positioning support platform, allows for fine-tuning of the pressing height of the upper positioning block, thereby fine-tuning the crimping depth. A limit locking bolt limits the adjustable positioning seat, improving its stability. A limit assembly, consisting of a limit rod, a limit top plate, and a spring, vertically limits the lower and upper positioning blocks, enhancing overall stability.
