Abstract
Description
Technical Field
[0001] This application relates to equipment or methods specifically for manufacturing, assembling, maintaining or repairing line connectors or current collectors, or specifically for connecting electrical conductors, and more particularly to a wire splicing fixture. Background Technology
[0002] In fields such as electronic equipment, automobile manufacturing, industrial automation, and new energy, wire harnesses serve as the core carrier for signal transmission and power supply, and their assembly quality directly determines the reliability and safety of equipment operation. Wire harnesses are typically integrated from multiple wires (conductors, cables, etc.) and connected by sheaths, connectors, and other plug-in components. Among these, the assembly process of the wires with sheaths and connectors is particularly critical, requiring the wires to be precisely inserted into the pre-set plug-in interfaces of the components to ensure the stability of the electrical connection and the reliability of the mechanical fixation.
[0003] However, in existing technologies, the assembly of wires with sheaths, connectors, and other components relies primarily on manual operation. Operators must hold the wire, align it with the connector on the component, and apply force to complete the connection. Experience is crucial in controlling the insertion force to ensure proper insertion and connection. In manual operation, variations in operator habits, fatigue levels, and experience can lead to inconsistent insertion force. Excessive force can deform the connector, damage the wire ends (such as cracking of crimp terminals), and even damage the internal structure of the sheath. Insufficient force can result in insufficient insertion depth, poor connection, or increased contact resistance, leading to signal distortion, abnormal temperature rise, and other problems. This is particularly problematic in high-voltage harnesses (such as those used in new energy vehicle batteries) or high-frequency signal harnesses (such as those used in 5G communication equipment), where such defects significantly reduce product lifespan and increase safety hazards.

[0005] A wire splicing fixture includes a worktable and a splice socket mounted on the worktable. The splice socket is mounted on the worktable by an elastic component. The splice socket is provided with an insertion slot for receiving a splice. The insertion slot is also provided with a limiting component for limiting the splice within the insertion slot.
[0006] It also includes a sensor and an alarm electrically connected to the sensor. The sensor is used to detect the displacement of the connector, and the alarm is used to sound an alarm when the distance between the connector and the workbench exceeds a preset value.

A plurality of plug-in sockets are installed on the movable platform. The main body has a plurality of storage stations on one side of the movable platform. The movable platform can be displaced on one side of the plurality of storage stations under the action of external force.
[0009] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the main body is provided with the movable platform on both sides of the storage station, and the plug-in socket is installed on each of the movable platforms.
[0010] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the limiting component includes a limiting member disposed at the opening of the insertion slot, and the limiting member is connected to the plug-in seat by a spring.

[0014] The beneficial effects of this utility model are as follows: Sheaths, connectors, and other plug-in components are inserted into the insertion slot, and the plug-in components are limited within the insertion slot by a limiting component. Then, the wire is inserted into the plug-in component located in the insertion slot, and the wire connected to the plug-in component is pulled.

[0024] Reference Figure 1-4 The present application proposes an embodiment of the wire splicing fixture, which includes a workbench 10 and a splice 20 mounted on the workbench 10. The splice 20 is mounted on the workbench 10 by an elastic component 30. The splice 20 is provided with an insertion groove 21 for accommodating a splice, and the insertion groove 21 is also provided with a limiting component 40 for limiting the splice within the insertion groove 21.
[0025] When using the wire splicing fixture described in this embodiment, the sheath, connector, and other splice components are inserted into the insertion slot 21, and the splice components are limited within the insertion slot 21 by the limiting component 40. Then, the wire is inserted into the splice located in the insertion slot 21, and the wire connected to the splice is pulled. If the wire and splice are stably connected, when the wire is pulled, the wire will cause the splice and the splice base 20 to simultaneously overcome the elastic tension of the elastic component 30 and move away from the worktable 10. If the wire and splice are not properly connected, the wire will detach from the splice when the wire is pulled. Therefore, the wire splicing fixture of this application can realize the splicing and splicing quality detection of wires, is easy to use, and improves product quality consistency while reducing the failure rate.
[0026] See attached document Figure 4 As shown, the movable platform 12 is provided with mounting holes. The elastic component 30 includes a plug rod installed at the lower end of the plug-in seat 20 and an elastic element sleeved on the plug rod. The plug rod is inserted into the mounting hole, and the elastic element on the plug rod is connected to the abutment seat and the movable platform.
[0027] Preferably, the device also includes a sensor 50 and an alarm 60 electrically connected to the sensor 50. The sensor 50 is used to detect the displacement information of the connector 20, and the alarm 60 is used to sound an alarm when the distance between the connector 20 and the workbench 10 exceeds a preset value.
[0028] When the wire is pulled, the sensor 50 detects the displacement of the connector 20. When the distance between the connector 20 and the workbench 10 reaches a preset distance, the alarm 60 sounds, and the operator is informed by the alarm 60 that the wire is properly connected to the connector. Therefore, in this embodiment, the cooperation of the sensor 50 and the alarm 60 unifies the detection standard for whether the wire is stably connected, avoiding excessive or insufficient pulling of the wire.
[0029] The alarm 60 can be an audible or visual alarm 60. In this embodiment, the alarm 60 is a buzzer. The buzzer has a loud sound and can effectively transmit information to the staff.
[0030] The sensor 50 can be a distance sensor 50 or a proximity sensor 50. In this embodiment, the proximity sensor 50 is disposed on the worktable 10 and faces the plug-in 20 to detect the displacement information of the plug-in 20.
[0031] Preferably, the workbench 10 includes a body 11 and a movable platform 12 installed on the upper end of the body 11. Multiple plug-in sockets 20 are installed on the movable platform 12. The body 11 has multiple storage stations 13 on one side of the movable platform 12. The movable platform 12 can be displaced on one side of the multiple storage stations 13 under the action of external force.
[0032] Each of the aforementioned plug sockets 20 can be equipped with plugs such as sheaths and connectors that are compatible with different models. Different models of sheaths or connectors require different models of wires to be plugged in. Therefore, in this embodiment, different models of storage stations 13 are also provided on the main body 11. Each storage station 13 holds different models of wires. When plugging in different models of sheaths or connectors, the movable platform 12 can be moved on the main body 11 to the corresponding storage station 13 to retrieve the wires, making it more convenient to use.
[0033] In this embodiment, the movable platform 12 is provided with wheels 121 that can roll along the length of the body 11, so that the movable platform 12 can be moved in front of all storage stations 13 on the body 11 by means of the wheels, which is convenient to use.
[0034] Specifically, the limiting component 40 includes a limiting member 41 disposed at the opening of the insertion slot 21, and the limiting member 41 is connected to the plug-in seat 20 by a spring 42.
[0035] In this embodiment, the limiting member 41 is set at the slot and pressed against the upper end of the plug-in to limit the plug-in. After the plug-in is inserted, the limiting member 41 is displaced and inserted outside the slot of the slot 21 by overcoming the elastic tension of the spring 42, so that the plug-in can be taken out from the plug-in seat 20.
[0036] Preferably, the limiting member 41 is a wedge-shaped block. Referring to the accompanying drawings, the upper surface of the wedge-shaped block is an inclined surface 411, and the upper end of the inclined surface 411 is distributed at the edge of the slot or located outside the slot, while the lower end of the inclined surface 411 extends into the slot. When the connector is inserted into the insertion slot 21, the connector pushes the wedge-shaped block out of the slot via the inclined surface 411, facilitating the insertion of the connector into the insertion slot.
[0037] Specifically, the upper end of the plug-in base 20 is provided with a socket 22, the plug-in base 20 is provided with a guide post 23 in the socket 22, the limiting member 41 extends into the socket 22 and is slidably installed on the guide post 23, and the spring 42 is connected to the plug-in base 20 and the limiting member 41.
[0038] Preferably, the plug-in base 20 has a threaded hole 24 on the side of the plug 22 near the insertion groove 21, and the guide post 23 is a bolt, which is threadedly connected to the threaded hole 24. The structure is simple and easy to assemble.
