Description

Technical Field

[0001] This application relates to the field of connectors, and in particular to a split-connector. Background Technology

[0002] In the wiring connection scenarios of electronic devices, it is often necessary to split a main wire harness into multiple sub-wire harnesses, or conversely, to integrate multiple sub-wire harnesses into a main wire harness (i.e., "split and combined wiring connection"). For example, the instrument panel wiring harness inside a car needs to be split into different components such as lights and sensors, and multiple sensor wiring harnesses in an industrial control cabinet need to be integrated and connected to the main control module.

[0003] Traditional connectors require manually stripping the insulation of the sub-wire harness (wire breaking operation), inserting the exposed wires into the terminal block, and finally soldering them in place. For multiple sub-wire harnesses (such as 6-8 sets), each set requires 3-5 steps, and the overall wiring process is time-consuming, making it difficult to meet the needs of mass assembly.

[0004] To solve the above problems, this utility model proposes a split-connector for circuits. Utility Model Content

[0005] The purpose of this application is to solve the technical problems of cumbersome wiring steps and poor disassembly and maintenance convenience of existing split-connector circuits. Compared with the prior art, a split-connector circuit is provided, including an end cover and a connector head. The connector head is provided with a plurality of connecting terminals evenly distributed at equal angles. The connecting terminals include plug terminal tubes and wiring terminal tubes. A wire pressing groove is provided between the two sets of radially arranged connecting terminals. A wire pressing ring is also provided between the connecting terminals. The wire pressing ring is fixed to the connector head. A plurality of wire pressing blocks are evenly distributed on the wire pressing ring. The wire pressing blocks are paired up to form a group. A U-shaped elastic connection part is fixed between one end of the wire pressing blocks in the same group. The opposite sides of the wire pressing blocks in the same group extend into the wire pressing groove and are fixed with a wire breaking knife. An anvil plate that cooperates with the wire breaking knife is fixed on the inner wall of the wiring terminal tube.

[0006] A pressure ring is slidably connected to the inner side of the end opposite to the end cap of the connector. A return spring is clamped between the pressure ring and the connector. An execution ring is fixed to one side of the pressure ring. The execution ring extends to the same group of pressure blocks.

[0007] A compression ring block is fixed to the inner side of the end cap opposite to the connector.

[0008] Furthermore, the end cap is used to fix and encapsulate the wire harness, and one end of the wire harness extending into the end cap is provided with a sub-wire harness corresponding to the terminal tube.

[0009] Furthermore, the end of the connector opposite to the end cap is provided with a male threaded groove and a female threaded groove, respectively.

[0010] Furthermore, the return spring has an elastic force that drives the pressure ring away from the pressure ring, and in the free state, the actuating ring moves away from the pressure block;

[0011] The U-shaped elastic connection has an elastic force that drives the two sets of pressure blocks to move closer together.

[0012] Furthermore, each of the two pressure blocks in the same group has an inclined groove on one side facing the other, and the execution ring is fixed with an extrusion ball that cooperates with the inclined groove.

[0013] Furthermore, the anvil is electrically connected to the terminal block, and the anvil is provided with several anti-detachment raised textures.

[0014] Compared to existing technologies, the advantages of this application are:

[0015] This invention eliminates the need to pre-strip the insulation layer of the wire harness; wire breaking and connection are completed simply by tightening the end cap, simplifying the operation process and improving work efficiency. The combination of the wire breaking knife and the anvil achieves a stable electrical connection, while the anti-detachment textured design enhances mechanical fixation, maintaining good connection performance even in vibration environments. The connection terminals are evenly distributed at equal angles, with each group of lines clearly corresponding, facilitating identification and troubleshooting. Different numbers of connection terminals can be configured as needed, making it suitable for various wire connection scenarios. Attached Figure Description

[0024] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0025] Example:

[0026] This utility model provides a split-connector for circuits. Please refer to [link / reference]. Figure 1 - Figure 6 It includes an end cap 2 and a connector 1. The connector 1 has several connector terminals 4 arranged at equal angles. This arrangement facilitates the identification and maintenance of the circuit. The connector terminals 4 include plug-in terminal tubes 41 and wiring terminal tubes 42. The plug-in terminal tubes 41 are used to connect to the interface of external equipment, and the wiring terminal tubes 42 are used to connect to the sub-wire harness 31.

[0027] Each of the two sets of radially arranged connecting terminals 4 is provided with a wire pressing groove 421. The wire pressing groove 421 is used to accommodate the wire pressing block 71 and provide a channel for it to be pressed into the inside of the terminal tube 42. A wire pressing ring 7 is also provided between the connecting terminals 4. The wire pressing ring 7 is fixed on the connector 1. Several wire pressing blocks 71 are evenly distributed on the wire pressing ring 7, and the wire pressing blocks 71 are paired up to form a group.

[0028] A U-shaped elastic connection 73 is fixed between one end of the same set of wire clamping blocks 71. The opposite sides of the same set of wire clamping blocks 71 extend into the wire clamping groove 421 and are fixed with wire breaking blades 72. The wire breaking blades 72 are used to pierce the insulation layer of the sub-wire harness 31. The inner wall of the terminal tube 42 is fixed with an anvil plate 43 that cooperates with the wire breaking blade 72. The anvil plate 43 and the wire breaking blade 72 cooperate to realize the electrical connection of the wire.

[0029] A pressure ring 5 is slidably connected to the inner side of the end opposite to the end cap 2 of the connector 1. A return spring 6 is clamped between the pressure ring 5 and the connector 1. An execution ring 51 is fixed on one side of the pressure ring 5. The execution ring 51 extends to the same group of wire pressing blocks 71 and is used to push the wire pressing blocks 71 to move.

[0030] A compression ring block 22 is fixed on the inner side of the end cap 2 opposite to the connector 1. When the end cap 2 is connected to the connector 1, the compression ring block 22 will push the pressure ring 5 to move against the elastic force of the return spring 6.

[0031] As a further improvement of this utility model, the end cap 2 is used to fix and encapsulate the wire harness 3. One end of the wire harness 3 extending into the end cap 2 is provided with a sub-wire harness 31 that corresponds one-to-one with the terminal tube 42, ensuring that each sub-wire harness 31 can be accurately connected to the corresponding connection terminal 4.

[0032] As a further improvement of this utility model, the end of the connector 1 opposite to the end cover 2 is provided with a male thread groove 11 and a female thread groove 21 respectively. The end cover 2 and the connector 1 are detachably connected by threaded connection, which is reliable and easy to operate.

[0033] As a further improvement of this utility model, the reset spring 6 has an elastic force that drives the pressure ring 5 away from the wire pressing ring 7. In the free state, the reset spring 6 drives the execution ring 51 away from the wire pressing block 71. The U-shaped elastic connection part 73 has an elastic force that drives the two sets of wire pressing blocks 71 to approach each other. This elastic design ensures that in the unconnected state, the wire breaking knife 72 is in the initial position and will not damage the wire.

[0034] As a further improvement of this utility model, each of the two pressure blocks 71 in the same group is provided with an inclined groove 711 on one side opposite to the other, and a compression ball 52 that cooperates with the inclined groove 711 is fixed on the actuating ring 51. Through the cooperation of the inclined groove 711 and the compression ball 52, the axial movement of the actuating ring 51 is converted into the radial movement of the pressure block 71, thereby realizing the wire breaking action.

[0035] As a further improvement of this utility model, the anvil plate 43 is electrically connected to the terminal tube 42 to ensure the continuity of the electrical path; the anvil plate 43 is provided with a number of anti-detachment ridges 431, which can enhance the reliability of contact with the wire and prevent the wire from loosening.

[0036] When using the split-connector of this utility model, the sub-wire harnesses 31 of the wire harness 3 are first placed into the terminal tube 42 respectively. The anti-detachment convex texture 431 is used to initially prevent the sub-wire harnesses 31 from detaching from the terminal tube 42. Then, the end cap 2 and the connector 1 are connected through the male thread groove 11 and the female thread groove 21.

[0037] As the end cap 2 is tightened, the compression ring block 22 on the inner side of the end cap 2 pushes the pressure ring 5 to move towards the pressure ring 7, compressing the return spring 6. The execution ring 51 on the pressure ring 5 moves accordingly, and the compression ball 52 on the execution ring 51 enters the inclined groove 711 of the pressure block 71, forcing the two sets of opposing pressure blocks 71 to overcome the elastic force of the U-shaped elastic connection part 73 and move away from each other.

[0038] As the wire clamping block 71 moves, the wire-breaking knife 72 on the clamping block 71 pierces into the insulation layer of the sub-wire harness 31 and comes into contact with the conductor core. When the end cap 2 is fully tightened, the wire-breaking knife 72 presses the conductor core onto the anvil plate 43, and an electrical connection is formed through the wire-breaking knife 72, the conductor core, and the anvil plate 43. At the same time, the anti-detachment ridges 431 on the anvil plate 43 ensure a firm and reliable connection.

[0039] When disassembly is required, unscrew the end cap 2, the pressure of the compression ring block 22 on the pressure ring 5 disappears, the return spring 6 pushes the pressure ring 5 to reset, the execution ring 51 leaves the wire pressing block 71, the U-shaped elastic connection part 73 drives the wire pressing block 71 to reset, the wire cutting knife 72 leaves the wire, and the wire harness 3 can be taken out, which facilitates the quick replacement of the wire harness 3.

[0040] This invention eliminates the need to pre-strip the insulation layer of the wire harness 3; wire breaking and connection are completed simply by tightening the end cap 2, simplifying the operation process and improving work efficiency. A stable electrical connection is achieved through the cooperation of the wire breaking knife 72 and the anvil 43. The anti-detachment textured surface 431 enhances the mechanical fixing effect, maintaining good connection performance even in vibration environments. The connecting terminals 4 are evenly distributed at equal angles, with each group of lines clearly corresponding, facilitating identification and troubleshooting. Different numbers of connecting terminals 4 can be set as needed, suitable for various wire connection scenarios.

[0041] The above description is only the best implementation method adopted in this application in combination with current practical needs, but the scope of protection of this application is not limited thereto.
