Detailed Description

The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

Referring to fig. 1, an embodiment of a socket connector with an anti-contact finger structure at the tail of the socket connector according to the present invention defines j directions of inserting an insulator cable member into a socket housing as "front" and j directions as "back". The present embodiment includes a socket housing 10, two insulator cable members 20 detachably fitted in the socket housing, and a locking piece 30 mounted on the outer housing and used for secondary locking of the two insulator cable members.

Referring to fig. 2, the insulator cable component 20 includes an insulator 201 and a copper bar cable component 202 installed in the insulator, the insulator 201 has a connecting arm 2011, a locking boss 20111 with a guiding inclined plane is disposed on the connecting arm, a tail portion of the connecting arm forms a pressure applying portion 20112, and for convenience of assembly, two connecting arms 2011 distributed up and down are disposed at a tail portion of each insulator; the copper bar 2021 containing the mold insert 2023 is welded with the cable 2022 to obtain a copper bar cable component 202, a limiting boss 2012 with a guide inclined plane is arranged on the insulator 201, and a limiting hole 20211 for the limiting boss to be clamped in so as to install the copper bar cable component in the insulator is arranged on the copper bar 2021.

The insulator cable component is detachably mounted in the socket housing by a snap-fit structure. Referring to fig. 3, in the present embodiment, the locking structure includes a locking hole 101 disposed at the tail of the receptacle housing, and a locking boss 20111 disposed on the connecting arm at the tail of the insulator, when the insulator cable component 20 is installed in the receptacle housing 10, the locking boss 2011 is locked into the locking hole 101 by means of the guiding inclined plane, so as to implement primary locking, and at this time, the locking boss is in a locking position; when the insulator cable component needs to be removed, the pressure applying portion 20112 applies a force F to make the locking boss 20111 disengage from the locking hole 101, and the locking boss moves from the locking position to the unlocking position, so that the insulator cable component can be taken out from the socket housing. Further, in consideration of the requirement of an operation space when a product is unlocked, the pressure applying portion 20112 is provided higher than the locking boss 20111 so as to form a recess 20113 therebetween, and when the insulator cable member is installed in the receptacle housing, after the locking boss is snapped into the locking hole, the receptacle housing located at the rear side of the locking hole is dropped into the recess 20113, so that the surface of the receptacle housing and the surface of the pressure applying portion are in a flush state.

Furthermore, in order to prevent the phenomenon that the insulator cable component is separated from the socket shell due to the failure of the primary locking under the action of external force, the invention adopts the locking piece to carry out secondary locking on the insulator cable component. Referring to fig. 4A and 4B, the locking plate 30 is hinged to the socket housing 10 through a rotation shaft; the insulator 201 is provided with a locking protrusion 2013, the tail part of the locking sheet 30 is provided with a barb 301, after the insulator cable component is installed in the socket shell, the locking sheet is rotationally buckled along the-i direction (namely the direction opposite to the i direction), so that the barb 301 is reversely buckled on the surface of the locking protrusion 2013, secondary locking is realized, and at the moment, the barb is in a secondary locking position; the locking piece is rotated in the direction i to separate the barb 301 from the locking protrusion 2013, and the barb is in the secondary unlocking position. Except the effect of secondary locking, the lock plate still plays the effect of supplementary and inspection to the buckle structure, specifically does: if the insulator cable component is not assembled in place when being installed in the socket shell, namely one-time locking is not completed, the barb is blocked by the locking protrusion, and the locking piece cannot be buckled down. Furthermore, in order to avoid the phenomenon that the barb is buckled and then collides with the insulator at the rear side of the locking protrusion to damage the locking plate or the insulator, the invention arranges a limiting lug at least one side of the locking plate, and arranges a limiting part (such as a step and a groove) on the socket shell for forming a stopping fit with the limiting lug so that the buckled barb is not contacted with the insulator at the rear side of the locking protrusion, in this embodiment, the limiting lugs 302 are arranged at two sides of the barb 301 at the tail part of the locking plate, and the step 102 is arranged at the tail part of the socket shell 10.

The embodiment comprises two insulator cable components 20, when the electrified cable and the tail part of the socket are connected in the equipment, because the connecting parts of the copper bars and the cable are wrapped in the insulator, an operator only needs to hold the insulator 201 and insert the insulator into the socket shell 10 along the j direction to complete the connection of the electrified cable and the tail part of the socket, and the function of preventing the contact fingers is realized through the insulator in the whole assembling process; when the insulator is inserted into the socket housing, the locking boss 20111 and the locking hole 101 form a buckling structure to perform primary locking, and in order to prevent primary locking failure, the locking piece 30 is rotated along the-i direction to enable the barb 301 to be simultaneously buckled on the outer surfaces of the locking protrusions 2013 at the tail parts of the two insulators to perform secondary locking, so that reliable connection between the two insulator cable components and the socket housing is ensured.

During unlocking, the locking sheet is rotated along the direction i to separate the barb from the locking bulge, and one-time unlocking is completed; and pressing the pressure applying part at the tail part of the corresponding insulator to enable the locking boss to be disengaged from the locking hole, enabling the locking of the buckle structure to be invalid, and completing secondary unlocking, wherein the corresponding insulator cable component can be taken out along the-j direction.

The present embodiment employs two insulator cable components of a split structure, but in other embodiments, an insulator cable component of an integrated structure may also be employed, where the component has two mounting holes for mounting the copper busbar cable component.

The above description is only a preferred embodiment of the present invention, and any person skilled in the art can make any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the present invention without departing from the scope of the present invention, and still fall within the scope of the present invention.
