[0025] Embodiment 1

[0026] Reference Figures 1-6 The embodiment provides a connecting shell for a connector, which aims at solving the problem of high processing cost when designing different structures of the shell of the existing connector, and the specific structure in the embodiment will be described in detail below.

[0027] The connecting shell for the connector comprises a connecting shell 1 and a connecting ring 2.

[0028] Specifically, the connecting ring 2 is sleeved on the connecting shell 1 and connected in rotation, a clasp 3 is arranged between the connecting ring 2 and the connecting shell 1, two protruding keys 31 are oppositely arranged on the clasp 3, and a plurality of recesses 12 matched with the protruding keys 31 are arranged on the connecting shell 1.

[0029] In the embodiment, the connecting ring 2 is sleeved on the connecting shell 1 and connected in rotation, when the connecting ring 2 is rotated, the clasp 3 is rotated relative to the connecting shell 1, when the protruding keys 31 on the clasp 3 fall into the recesses 12 of the connecting shell 1, the clasp 3 is fixed, so that the protruding keys 31 fall into different recesses 12 on the connecting shell 1 according to different requirements, the switching of the index is completed, and the connector itself has different indexes, without the need of separately designing different shells, thereby reducing the processing cost.

[0030] Specifically, a tab 32 is oppositely arranged on the clasp 3, an annular plate 21 is arranged on the inner wall of the connecting ring 2, an installation groove 22 matched with the tab 32 is formed in the annular plate 21, the clasp 3 is arranged below the annular plate 21, and the tab 32 is embedded in the installation groove 22.

[0031] In the embodiment, the clasp 3 is arranged inside the connecting ring 2 and below the annular plate 21, so that the tab 32 on the clasp 3 is embedded in the installation groove 22 on the annular plate 21, and when the connecting ring 2 is rotated, the clasp 3 is rotated under the cooperation of the tab 32 and the installation groove 22.

[0032] Specifically, a positioning step 23 acting on the tab 32 is arranged on the inner wall of the connecting ring 2 above the annular plate 21.

[0033] In the embodiment, the spacing between the positioning step 23 and the annular plate 21 is less than or equal to the height of the tab 32, so that the tab 32 is limited by the positioning step 23.

[0034] Specifically, the outer middle part of the connecting shell 1 is provided with a connecting plate 11, and the upper surface of the connecting plate 11 is uniformly provided with a plurality of grooves 12 matched with the protrusions 31; the collar 3 is placed on the upper surface of the connecting plate 11, and the protrusions 31 are embedded in the grooves 12.

[0035] In the embodiment, the connecting plate 11 is annular and is arranged at the outer middle part of the connecting shell 1, and a plurality of grooves 12 are uniformly arranged on the upper surface of the connecting plate 11 and matched with the protrusions 31. The grooves 12 are four in number and are uniformly arranged on the connecting plate 11, thereby forming four positions. When the connecting ring 2 is rotated, the collar 3 is rotated with the connecting ring 2 relative to the connecting shell 1. When the protrusions 31 on the collar 3 fall into the grooves 12 of the connecting shell 1, the collar 3 is fixed. Thus, according to different requirements, the protrusions 31 can fall into different grooves 12 of the connecting shell 1, the switching of the positions is completed, and the connector itself has different positions, so that different shells do not need to be designed separately, thereby reducing the processing cost.

[0036] Specifically, a first clamping groove 24 is arranged on the inner wall of the connecting ring 2, and a second clamping groove 13 matched with the first clamping groove 24 is arranged on the side wall of the connecting plate 11; and the first clamping groove 24 and the second clamping groove 13 are provided with the clamping ring 4.

[0037] In the embodiment, the clamping ring 4 is embedded between the first clamping groove 24 and the second clamping groove 13, so that when the connecting ring 2 is sleeved on the connecting shell 1, the connecting ring 2 can be rotated relative to the connecting shell 1.

[0038] Specifically, the inner wall of the connecting ring 2 above the mounting groove 22 is provided with the clamping nail 5, and the top end of the side wall of the connecting shell 1 is provided with the key plate 6.

[0039] In the embodiment, the four grooves 12 are uniformly arranged on the connecting plate 11, thereby forming four positions. When the connecting ring 2 is rotated, the collar 3 is rotated with the connecting ring 2 relative to the connecting shell 1. The clamping nail 5 rotates with the connecting ring 2. When the protrusions 31 on the collar 3 fall into the grooves 12 of the connecting shell 1, the collar 3 is fixed, so that the first relative position is formed between the clamping nail 5 and the key plate 6. Then, the connecting ring 2 is rotated again, the clamping nail 5 rotates with the connecting ring 2, and the position is changed. When the protrusions 31 on the collar 3 fall into the second groove 12 of the connecting shell 1, the collar 3 is fixed, so that the second relative position is formed between the clamping nail 5 and the key plate 6. Then, the third relative position and the fourth relative position are sequentially formed, so that the error prevention function is realized. Thus, the connector itself has different positions, so that different shells do not need to be designed separately, thereby reducing the processing cost.
