Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and more specifically, to a cable terminal block. Background Technology

[0002] Terminal blocks are used to facilitate the connection of wires. They are essentially metal plates encased in insulating plastic, with holes at both ends for inserting wires and screws for tightening or loosening. For example, if two wires sometimes need to be connected and sometimes disconnected, terminals can be used to connect them and disconnect them at any time without soldering or winding them together, which is very convenient and quick. They are also suitable for interconnecting large numbers of wires. In the power industry, there are specialized terminal blocks and terminal boxes filled with terminals—single-layer, double-layer, current-carrying, voltage-carrying, standard, disconnectable, etc. A certain crimping area ensures reliable contact and allows sufficient current to pass through.

[0003] Traditional cable terminals typically connect two cables via threaded connections, which is cumbersome. Furthermore, loose threads can lead to poor contact. Therefore, this invention provides a new type of cable terminal. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a cable terminal block, which solves the problem that in the prior art, cable terminals are generally fixed with screws to connect two cables, which is cumbersome to install. Moreover, if the screws become loose, it may lead to poor contact at the connection.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A cable terminal block includes a cable body. Two cable bodies are respectively fixedly connected to port one and port two at their close ends. One end of port one is fixedly connected to a core and a collar one. The collar one is fitted onto the outer circumferential surface of the core. A pair of snap-fit ​​connectors are fixedly connected to the outer circumferential surface of collar one. A connecting ring is fixedly connected to the outer circumferential surface of port two. A housing is fixedly connected to one side of the connecting ring. A coil spring is fixedly connected to the inner wall of the housing. One end of the coil spring is fixedly connected to collar two. A pair of diameter-changing channels are formed on the outer circumferential surface of collar two. The diameter-changing channels correspond to the snap-fit ​​connectors. A core cylinder is fixedly connected to one end of port two. The core cylinder is fitted into the core body.

[0009] Furthermore, an elastic petal-shaped interface is fixedly connected inside the core tube, and the elastic petal-shaped interface is clamped on the outer circumferential surface of the core.

[0010] Furthermore, the inner wall of one end of the variable diameter channel is inclined.

[0011] Furthermore, one end of the elastic petal-shaped interface is provided with an opening area.

[0012] Furthermore, one end of the core is arc-shaped.

[0013] 3. Beneficial effects

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) After installing Port 1 and Port 2 at the connection end of the two cable bodies respectively, the front end of Port 1 can be directly inserted into the front end of Port 2. When the core is embedded in the core tube, the two cable bodies can be connected. During the process of the core being embedded in the core tube, the collar 1 on the outer circumference of the core and the collar 2 on the outer circumference of the core tube will also be engaged. Since the collar 2 is directly fixed on the coil spring, when the clamping head on the outer circumference of the core tube is embedded in the variable diameter channel on the outer circumference of the collar 2, the clamping head will force the collar 2 to rotate automatically. At this time, the coil spring is also storing force and deforming. After the clamping head is embedded in place, the coil spring will release the elastic force and drive the collar 2 to reset. After the reset collar 2, the variable diameter channel on its circumference will lock the clamping head, and the collar 1 and the collar 2 will be locked together, which facilitates the quick connection of the two cable bodies.

[0016] (2) The core tube of this solution is provided with an elastic petal-shaped interface. When the core tube is embedded in the elastic petal-shaped interface, it will expand the elastic petal-shaped interface. The elastic petal-shaped interface that undergoes elastic deformation will be tightly clamped on the outer circumference of the core tube, which can effectively reduce the possibility of poor contact in the connection.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Example

[0025] like Figure 1-4 As shown, a cable terminal block includes a cable body 1. Two cable bodies 1 are respectively fixedly connected to port 1 2 and port 2 3 at their close ends. One end of port 1 2 is fixedly connected to a core 4 and a collar 1 5. The collar 1 5 is sleeved on the outer circumferential surface of the core 4. A pair of snap-fit ​​connectors 6 are fixedly connected to the outer circumferential surface of the collar 1 5. A connecting ring 7 is fixedly connected to the outer circumferential surface of port 2 3. A housing 8 is fixedly connected to one side of the connecting ring 7. A coil spring 9 is fixedly connected to the inner wall of the housing 8. A collar 2 10 is fixedly connected to one end of the coil spring 9. A pair of diameter-changing channels 1001 are opened on the outer circumferential surface of the collar 2 10. The diameter-changing channels 1001 correspond to the snap-fit ​​connectors 6. One end of port 2 3 is fixedly connected to a core cylinder 11, which is fitted into the core 4.

[0026] In use, the front end of port 1 (2) is directly inserted into the front end of port 2 (3). After the core 4 is embedded inside the core cylinder 12, the two cable bodies 1 can be connected. During the process of the core 4 being embedded into the core cylinder 12, the collar 1 (5) on the outer circumference of the core 4 and the collar 2 (10) on the outer circumference of the core cylinder 11 will also engage. Since the collar 2 (10) is directly fixed to the coil spring 9, when the clamping connector 6 on the outer circumference of the core cylinder 11 is embedded in the variable diameter channel 1001 on the outer circumference of the collar 2 (10), the clamping connector 6 will force the collar 2 (10) to rotate automatically. At this time, the coil spring 9 is also storing force and deforming. After the clamping connector 6 is embedded in place, the coil spring 9 will release its elastic force and drive the collar 2 (10) to reset. After the collar 2 (10) is reset, the variable diameter channel 1001 on its circumference will lock the clamping connector 6, thus clamping the collar 1 (5) and the collar 2 (10) together, which facilitates the quick connection of the two cable bodies 1.

[0027] like Figure 4 As shown, an elastic petal-shaped interface 12 is fixedly connected inside the core cylinder 11, and the elastic petal-shaped interface 12 is clamped on the outer circumferential surface of the core body 4.

[0028] When in use, the core tube 11 expands the elastic flap 12 when it is embedded in the elastic flap 12. The elastic flap 12, which undergoes elastic deformation, will be tightly clamped on the outer circumferential surface of the core tube 12, which can effectively reduce the possibility of poor contact during connection.

[0029] like Figure 2-3 As shown, the inner wall of one end of the variable diameter channel 1001 is inclined.

[0030] When in use, the opening at the end of the variable diameter channel 1001 near the card connector 6 can be widened to facilitate the insertion of the card connector 6.

[0031] like Figure 4 As shown, one end of the elastic petal-shaped interface 12 is provided with an opening area 1201.

[0032] In use, one end of the elastic flap-shaped interface 12 can be wider than the core 4, thereby facilitating the core 4 to be embedded in the elastic flap-shaped interface 12.

[0033] like Figure 4 As shown, one end of the core 4 is arc-shaped.

[0034] When in use, compared to the angular insertion end, its arc-shaped end can reduce the scratches on the surface of the elastic flap 12 when it is inserted into the elastic flap 12, which can effectively reduce the wear of the elastic flap 12 and improve its service life.

[0035] In summary, the specific working process of this solution is as follows: the front end of port 12 is directly inserted into the front end of port 23. When the core 4 is embedded inside the core cylinder 12, the two cable bodies 1 can be connected. During the process of the core 4 being embedded into the core cylinder 12, the collar 15 on the outer circumference of the core 4 and the collar 20 on the outer circumference of the core cylinder 11 will also be engaged. Since the collar 20 is directly fixed on the coil spring 9, when the clamping connector 6 on the outer circumference of the core cylinder 11 is embedded in the variable diameter channel 1001 on the outer circumference of the collar 20, the clamping connector 6 will force the collar 20 to rotate automatically. At this time, the coil spring 9 is also storing force and deforming. After the clamping connector 6 is embedded in place, the coil spring 9 will release its elastic force and drive the collar 20 to reset. After the reset collar 20, the variable diameter channel 1001 on its circumference will lock the clamping connector 6, and the collar 15 and the collar 20 will be locked together, which facilitates the quick connection of the two cable bodies 1.

[0036] The core cylinder 12 is provided with an elastic petal-shaped interface 12. When the core cylinder 11 is inserted into the elastic petal-shaped interface 12, it will expand the elastic petal-shaped interface 12. The elastically deformed elastic petal-shaped interface 12 will be tightly clamped on the outer circumferential surface of the core cylinder 12, which can effectively reduce the possibility of poor contact in the connection.

[0037] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
