Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically to an assembly connector. Background Technology

[0002] M16 circular connectors are widely used connection solutions in industrial automation, communications, military, and other demanding environments. They are classified by termination method, including soldered and assembled types. Soldered connections offer high reliability but are inconvenient to disassemble; assembled connections are easy to install, allowing for quick connection and disassembly, and provide a stable connection. Based on connector structure, they are divided into male and female types. The male connector is used for insertion, and the female connector is used for receiving insertion; the two work together to achieve connector mating. Female connectors are mostly soldered, while male connectors are mostly assembled.

[0003] Most existing modular connectors have a sealing ring fixedly installed at the connection between the cable and the tail clip sheath. The sealing ring seals the connection between the cable and the tail clip sheath. When the diameter of the cable is smaller than the inner diameter of the sealing ring, the sealing effect of the sealing ring is poor, and it is easy to fail to seal properly, which affects the normal use of the connector. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an assembled connector to solve the problem that when the diameter of the cable is smaller than the inner diameter of the sealing ring, the sealing effect of the sealing ring is poor, and it is easy to fail to seal properly, which affects the normal use of the connector.

[0005] This utility model provides the following technical solution:

[0006] An assembled connector includes a copper alloy outer shell and an inner protective shell fixedly installed inside the copper alloy outer shell. A bracket is inserted into the inner protective shell, a connector is inserted into the bracket, a wire clip is fixedly installed on the bracket, and a cable is held in the wire clip. A protective component is provided around the bracket, a sealing component is provided inside the protective component, and a connecting component is provided on the protective component. The sealing component is connected to the protective component through the connecting component, which improves the sealing effect and prevents the cable from loosening.

[0007] Furthermore, the protective component includes a plastic shell, a connecting cavity formed between the copper alloy shell and the inner protective shell, an internal connecting thread on the inner wall of the copper alloy shell, the plastic shell being fitted around the periphery of the bracket, an external connecting thread on the periphery of the plastic shell, the end of the plastic shell near the copper alloy shell located within the connecting cavity, the external connecting thread being threadedly connected to the internal connecting thread, a placement cavity being formed inside the plastic shell, the inner diameter of the placement cavity gradually decreasing on the side away from the copper alloy shell to form an inner conical surface, and a through hole being formed at the end of the plastic shell away from the copper alloy shell.

[0008] Furthermore, the sealing assembly includes a tail clip sleeve, one end of which is located inside the plastic shell. The tail clip sleeve has several clearance grooves arranged in a circular array at one end, and a rotating block is rotatably connected to each of the clearance grooves.

[0009] Furthermore, the connecting assembly includes an external threaded cylinder and an internal threaded cylinder. The external threaded cylinder is fixedly connected to the periphery of the tail clip sheath, and the internal threaded cylinder is fixedly connected to the plastic shell. The internal threaded cylinder extends into the through hole of the plastic shell, and the external threaded cylinder and the internal threaded cylinder are threadedly connected.

[0010] Furthermore, a rubber ring is provided inside the plastic shell, and the rubber ring is sleeved around the periphery of the cable. The side of the rotating block closest to the rubber ring abuts against the rubber ring, and the side of the rotating block away from the rubber ring abuts against the inner conical surface of the placement cavity.

[0011] Furthermore, the cable passes through the plastic shell, rubber ring, tail clip sheath and extends to the outside.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up protective and sealing components, this utility model allows the tail clip sheath to rotate and move away from the copper alloy shell. When the tail clip sheath rotates and moves away from the copper alloy shell, the inner cone surface of the placement cavity presses the rotating block away from the rubber ring. The pressed rotating blocks rotate uniformly towards the rubber ring. The simultaneous pressing of several rotating blocks on the rubber ring causes the rubber ring to tightly clamp the cable and seal it, improving the sealing effect, enhancing the stability of the cable connection, and making it less prone to loosening.

[0014] 2. By setting up a connecting component, the tail clip sleeve is stably installed on the plastic shell through the connecting component, which effectively avoids the tail clip sleeve from shifting due to the force generated by the rotating block abutting against the conical surface inside the placement cavity.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Appendix Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0022] See attached document Figures 1-4 An assembled connector includes a copper alloy shell 1 and an inner protective shell 2 fixedly installed inside the copper alloy shell 1. A bracket 3 is inserted into the inner protective shell 2, and a connector 4 is inserted into the bracket 3. A wire clip 5 is fixedly installed on the bracket 3, and a cable 9 is held in the wire clip 5. A protective component is provided around the bracket 3, and a sealing component is provided inside the protective component. A connecting component is provided on the protective component, and the sealing component is connected to the protective component through the connecting component.

[0023] Specifically, the protective component includes a plastic shell 7, a copper alloy shell 1, and an inner protective shell 2 forming a connecting cavity 6. The inner wall of the copper alloy shell 1 is provided with an internal connecting thread 10. The plastic shell 7 is sleeved on the periphery of the bracket 3. The periphery of the plastic shell 7 is provided with an external connecting thread 11. The end of the plastic shell 7 near the copper alloy shell 1 is located in the connecting cavity 6. The external connecting thread 11 is threadedly connected to the internal connecting thread 10. A placement cavity 12 is opened inside the plastic shell 7. The inner diameter of the placement cavity 12 gradually decreases on the side away from the copper alloy shell 1 to form an inner conical surface. A through hole is opened on the end of the plastic shell 7 away from the copper alloy shell 1.

[0024] Specifically, the sealing assembly includes a tail clip sleeve 8, one end of which is located inside the plastic housing 7. The tail clip sleeve 8 has several clearance grooves 13 arranged in a circular array at one end, and a rotating block 14 is rotatably connected to each of the clearance grooves 13.

[0025] Specifically, the connecting assembly includes an external threaded cylinder 16 and an internal threaded cylinder 17. The external threaded cylinder 16 is fixedly connected to the periphery of the tail clip sleeve 8, and the internal threaded cylinder 17 is fixedly connected to the plastic shell 7. The internal threaded cylinder 17 extends into the through hole of the plastic shell 7, and the external threaded cylinder 16 and the internal threaded cylinder 17 are threadedly connected.

[0026] In this embodiment, the external threaded cylinder 16 and the internal threaded cylinder 17 allow the tail clip sleeve 8 to be mounted on the plastic housing 7, thereby preventing the tail clip sleeve 8 from shifting due to the force of the rotating block 14 against the inner conical surface of the placement cavity 12.

[0027] Specifically, a rubber ring 15 is provided inside the plastic shell 7. The rubber ring 15 is sleeved around the periphery of the cable 9. The side of the rotating block 14 close to the rubber ring 15 abuts against the rubber ring 15, and the side of the rotating block 14 away from the rubber ring 15 abuts against the inner conical surface of the placement cavity 12.

[0028] In this embodiment, when the side of the rotating block 14 away from the rubber ring 15 is squeezed by the inner conical surface of the placement cavity 12, the squeezed rotating block 14 rotates uniformly toward the rubber ring 15, thereby causing several rotating blocks 14 to squeeze the rubber ring 15 so that the rubber ring 15 tightly clamps the cable 9 to seal it.

[0029] Specifically, cable 9 passes through plastic shell 7, rubber ring 15, tail clip sheath 8 and extends to the outside.

[0030] The working principle and usage process of this utility model are as follows: In use, the operator first inserts the smaller diameter end of the tail clip sleeve 8 into the plastic shell 7, then slightly pulls the tail clip sleeve 8 to allow the rotating block 14 to enter the placement cavity 12. The operator first places the rubber ring 15 around the periphery of the cable 9, then passes the cable 9 through the tail clip sleeve 8 and the plastic shell 7 in sequence. At this time, the rubber ring 15 is located inside the plastic shell 7. The end of the plastic shell 7 closest to the copper alloy shell 1 is inserted into the connecting cavity 6, so that the external connecting thread 11 and the internal connecting thread 10 are threadedly engaged. During this process, the plastic shell 7 moves closer to the copper alloy shell 1, and the operator rotates the tail clamp sleeve 8 to make the external threaded cylinder 16 and the internal threaded cylinder 17 threadedly connected. At this time, the tail clamp sleeve 8 drives the rotating block 14 in the relief groove 13 to move away from the copper alloy shell 1. The side of the rotating block 14 away from the rubber ring 15 is squeezed by the inner conical surface of the placement cavity 12. The squeezed rotating blocks 14 rotate uniformly towards the rubber ring 15. Several rotating blocks 14 squeeze the rubber ring 15 so that the rubber ring 15 tightly clamps the cable 9 to seal it.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
