Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a fast rotation limiting structure for connectors. Background Art

[0002] In the prior art, spring-clip wire-pressing terminal blocks are widely used. When connecting wires, traditional spring-clip blocks need to be pressed by auxiliary tools to open and close, and cannot be released. When the opening and closing state is formed, the cable is connected; when removing, the auxiliary tool is also pressed continuously to form an opening and closing state to remove the cable. When the pressing is stopped, the initial state is restored. During the process of loading and removing, the operator needs to keep pressing the push block, which is not conducive to operation.

DETAILED DESCRIPTION

[0023] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0024] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0025] In this embodiment, the insulating cover 4 is as follows Figure 2 As shown, the insulating cover 4 is provided with a plurality of guide grooves 4 - 1 and wiring holes 4 - 2 , one guide groove 4 - 1 and one wiring hole 4 - 2 form a group, and the positions of the guide grooves 4 - 1 and the wiring holes 4 - 2 on the insulating shell 3 correspond to each other.

[0026] like Figure 3 As shown, the insulating housing 3 is also provided with a plurality of mounting holes 3-2, and a limiting step 3-1 is provided at the mounting hole 3-2 corresponding to the position of the guide groove 4-1, and the entire limiting step 3-1 is radially arranged along the mounting hole 3-2. When the insulating cover 4 is installed on the insulating housing 3, a limiting groove is formed between the lower surface of the insulating cover 4 and the limiting step 3-1.

[0027] like Figure 4 As shown, the quick wire clamping mechanism in this embodiment includes a metal conductive bracket 5, a spring 6 fixed at one end to the conductive bracket 5 and suspended at the other end, and the floating end of the spring 6 is in contact with the conductive bracket 5 due to the elasticity of the spring itself. An insulating push block 1 is arranged on the spring 6, and the bottom of the insulating push block 1 is in contact with the spring 6. When the insulating push block 1 is acted downward by force, force can be applied to the spring 6, so that the spring 6 is deformed and separated from the conductive bracket 5, so that the cable can be inserted between the conductive bracket 5 and the spring 6, and then the insulating push block 1 is released, and the spring 6 is reset under the action of elastic force, so that the cable is clamped on the conductive bracket 5. A jack assembly 7 is connected to the lower end of the conductive bracket 5 for the end-to-end plug-in function of the connector.

[0028] In this embodiment, if Figure 5 The figure shows the rotating structure of the insulating push block 1, which is also the key structure of this embodiment. A rotating block 2 capable of rotation is arranged at the upper end of the insulating push block 1, and the rotating block 2 is connected to the insulating push block 1 by a movable connection. A protruding stop block 2-1 is arranged radially on the outer side of the rotating module 2, and the stop block 2-1 mainly cooperates with the stop step 3-1 to achieve rotation stop locking. In this embodiment, the connection between the insulating push block 1 and the rotating module 2 is axially connected. Through the conventional stop structure, the rotating module 2 cannot move axially in the insulating push block 1, but can rotate freely along the axial direction.

[0029] The working principle of this embodiment is as follows:

[0030] Install the assembled conductive bracket and spring 6 into the installation hole of the insulating housing, and then install the insulating push block 1 above the spring 6, ensuring that the limit block 2-1 on the rotating module 2 is set above the limit step 3-1. Install the insulating cover 4, ensuring that the guide groove 4-1 corresponds to the position of the limit block 2-1. After all the installations are completed, Figure 1 As shown, the spring piece 6 is in a free state at this time. Use a tool to push the insulating push block 1 downward so that the limit block 2-1 contacts the limit step 3-1, and then rotate the rotating module 2 so that the limit block 2-1 is misaligned with the guide groove 4-1, so that the limit block 2-1 is stuck by the insulating cover 4, thereby realizing the axial limit of the insulating push block 1.

[0031] This embodiment can be operated manually, and each operation link can reflect visual operation. It is not limited by the proficiency of the operator when in use; the new limit structure can effectively solve the disadvantage that the same type of connectors in the past cannot be quickly connected in large quantities.

[0032] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
