Description

Technical Field

[0001] The present application relates to the technical field of cable connecting tubes, and in particular to a connection structure between a connecting tube and a connecting ring. Background Art

[0002] In power systems and related industries, the reliability and safety of cable connections are of vital importance. In order to achieve effective connection between cables, cable connectors are usually used for connection. The cable connectors mainly include a connecting tube, a connecting ring and an elastic positioning assembly. A slot is provided at one end of the connecting tube, and an elastic positioning assembly is arranged in the slot, while an alignment notch aligned with the slot is provided on the connecting ring. When the connecting ring is assembled with the connecting tube, the alignment notch needs to be manually aligned with the positioning groove. This process often relies on the operator's sight and experience, and it is difficult to complete the alignment quickly and accurately. Moreover, due to the lack of an effective alignment limit mechanism, the connecting ring is prone to rotation after being inserted into the connecting tube, which causes the alignment notch to deviate from the slot and needs to be realigned. The operator needs to spend a lot of time and energy to align, which not only reduces work efficiency but also increases operating costs. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] The utility model provides a connection structure of a connecting pipe and a connecting ring.

[0023] In this embodiment, referring to Figure 1-4 The connection structure of the connecting pipe and the connecting ring includes a connecting pipe 1 and a connecting ring 2 sleeved on one end of the connecting pipe 1, a slot 3 is provided on one end of the connecting pipe 1, an elastic positioning component 4 is provided in the slot 3, an alignment notch 5 is provided on the connecting ring for aligning with the slot, a positioning groove 6 is provided on the inner wall of the connecting ring, and the positioning groove 6 is arranged along the length direction of the connecting ring, and the elastic positioning component is snapped into the above-mentioned positioning groove and slidably cooperates with the positioning groove.

[0024] In this embodiment, a positioning groove is provided on the inner wall of the connecting ring for sliding engagement with the elastic positioning assembly, and the elastic positioning assembly fits into the positioning groove, which can effectively prevent the connecting ring from rotating on the connecting pipe and causing the alignment notch to deviate from the groove.

[0025] In addition, due to the provision of the positioning groove, after the connecting ring is aligned and inserted into the connecting pipe, relative rotation will not occur, thereby improving the convenience of assembly and improving the assembly efficiency.

[0026] Specifically, the elastic positioning assembly 4 includes a positioning block 7 and a positioning spring 8. The positioning spring 8 is just inserted into the positioning groove and slides with the positioning groove.

[0027] In this embodiment, the width of the positioning spring is consistent with the width of the positioning groove, so that the positioning spring can be just stuck into the positioning groove and slide with it, thereby connecting the connecting ring and the connecting tube, and preventing relative rotation between the two after assembly.

[0028] Specifically, one end of the positioning block is rotatably connected to the rotating shaft 9 in the positioning groove, and the positioning spring is arranged between the connecting ring and the positioning block, and the positioning spring has a downward elastic pressure.

[0029] In this embodiment, after the wiring lug connected to the cable is inserted into the connecting tube, the positioning block connects the wiring lug to the connecting tube under the downward elastic pressure of the positioning spring.

[0030] Specifically, the end of the positioning block away from the rotating shaft has a handle 10 extending to the outside of the connecting pipe, and the bottom of the positioning block has a positioning protrusion 11.

[0031] In this embodiment, by providing a handle, the positioning block can be manually lifted or lowered, so that the operator can more easily control and adjust the positioning block.

[0032] Specifically, the positioning spring piece includes a straight section 12 that fits with the inner wall of the connecting ring, a connecting section 13 connected to the positioning block, and an arc section 14 for connecting the straight section and the connecting section. A connecting hook 15 is provided on the end of the connecting section, and a groove 16 is provided on the positioning block to connect with the connecting hook.

[0033] In this embodiment, the positioning spring comprises a straight section, a connecting section, and an arcuate section. The straight section engages the chute to provide rotational positioning and sliding engagement. The connecting section connects to the positioning block, and the connection between the hook and the groove ensures a secure connection between the positioning spring and the block.

[0034] Specifically, the connecting ring has a bell-mouth portion 17 at one end connected to the connecting pipe, and a chamfer 18 is provided at the opening of the bell-mouth portion 17 .

[0035] The flared part and chamfer design at one end of the connecting ring make it easier to insert the connecting ring into the connecting pipe. The chamfer can reduce friction and damage during the assembly process, improve the smoothness of assembly and protect the integrity of the connecting pipe.

[0036] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
