[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It comprises: a protective cover component 4, which is nested and connected to the outer surface of the connector body 1, and a bottom positioning block 6 and a side positioning block 5 are respectively installed on the lower side and right side of the outer surface of the protective cover component 4, and a clamping block 3 is respectively engaged and connected on the inner surface of the side positioning block 5 and the bottom positioning block 6, and a limiting block 7 is installed on the left side of the outer surface of the connector body 1;

[0033] The extrusion block 8 is nested and connected to the outer surface of the limit block 7, and an extrusion spring 9 is connected between the extrusion block 8 and the limit block 7, and a limit assembly 10 is installed on the front side of the outer surface of the extrusion block 8, and a take-out groove 11 is opened on the upper and lower sides of the inner surface of the limit assembly 10;

[0034] The protective cover assembly 4 and the connector body 1 form a built-in nested structure, and the connector body 1 forms a limiting snap-fit ​​structure with the protective cover assembly 4 through the clamping block 3, the side positioning block 5 and the bottom positioning block 6, and the connector body 1 and the outer surface right side of the limiting block 7 are embedded and installed.

[0035] The extrusion block 8 and the limit block 7 constitute an extrusion limit structure, and the limit block 7 and the extrusion block 8 constitute a built-in elastic extrusion structure through an extrusion spring 9, and the extrusion block 8 and the limit assembly 10 constitute an integrated structure, and the removal slot 11 is symmetrically arranged about the middle section of the outer surface of the limit assembly 10.

[0038] When in use, the connector body 1 on which the pin locator 2, the pin body and the circuit are installed can be penetrated and nested in the inner surface of the protective sleeve component 4. The protective sleeve component 4 can form a limit engagement with the card block 3 installed on the connector body 1 through the installed side positioning blocks 5 and the bottom positioning blocks 6, and effectively form a preliminary positioning for the connector body 1. When the connector body 1 is nested in the protective sleeve component 4, the limit block 7 installed on the connector body 1 can be synchronously nested in the protective sleeve component 4, but no engagement positioning is formed. The limit assembly 10 is installed in conjunction with the extrusion block 8 used separately to form a nested limit for the limit block 7. An extrusion spring 9 is assembled between the limit block 7 and the extrusion block 8, and can be used in conjunction with the retrieval slot 11 opened by the limit assembly 10. When the protective sleeve component 4 is replaced later, the limit assembly 10 is controlled to rebound and be taken out. When it cannot rebound, it is placed in the retrieval slot 11 through a professional tool to take out the limit assembly 10.

[0039] When the limit assembly 10 is used for positioning, the limit assembly 10 is used synchronously with the extrusion block 8, and the rotating member 13 installed on the rotation shaft 12 is rotated to rotate. By using the arc-shaped slide groove 14 provided on the rotating member 13, the limit rod 17 assembled with the moving shaft 15 connected in the sliding control slide groove 14 slides in the limit position of the limit assembly 10, and the limit rod 17 is controlled to squeeze the reset spring 16 to form a contraction, until the limit rod 17 moves to the engaging position with the protective cover assembly 4, and the components of the control shaft 12 are loosened, and the limit rod 17 is controlled to slide and engage inside the protective cover assembly 4 through the expansion of the reset spring 16, so as to form a positioning for the connector body 1 embedded in the protective cover assembly 4;

[0041] The limiting shaft 23 is slidably connected to the front side of the outer surface of the clamp 19, and the outer surface of the limiting shaft 23 is nested with a second extrusion spring 22, and the second extrusion spring 22 is placed on the inner surface of the clamp 19, and the outer surface of the limiting shaft 23 is installed with a handle 21.

[0042] The rotating cover 18 and the protective cover assembly 4 form a rotating structure, and the rotating cover 18 forms a limiting snap-fit ​​structure with the positioning shaft 20 through the clamp 19, and the clamp 19 forms a pullable elastic sliding structure with the limiting shaft 23 through the handle 21 and the extrusion spring 22, and the limiting shaft 23 and the protective cover assembly 4 form a built-in positioning structure.

[0043] When problems occur to the internal pins and circuits of the connector body 1 in the protective cover assembly 4 after working for a long time, the handle 21 can be used to control the installed limit shaft 23 to squeeze the extrusion spring 22 connected through it, so that the limit shaft 23 is disengaged from the engagement with the protective cover assembly 4, thereby controlling the handle 21 to drive the clamping member 19 to form a positioning rotation on the rotating cover 18, thereby disengaging the clamping member 19 from the engagement with the positioning shaft 20, and controlling the rotating cover 18 and the protective cover assembly 4 to rotate, thereby opening the rear position of the protective cover assembly 4 to inspect and process the pins and circuits, as well as the connection between the two, to improve the stability of use.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
