Detailed Description
In an embodiment, referring to fig. 1 and 4, the insulating terminal sheath provided in this embodiment includes a housing, where an assembly cavity 1 having a square cross-sectional outline is disposed at a front portion of the housing, an outer surface of a cavity wall of the assembly cavity 1 gradually inclines toward an inner surface of the cavity wall in a sequence from back to front, a grip portion 2 having a circular cross-sectional outline is disposed at a tail portion of the housing, a front end of a middle portion 3 of the housing is connected to the assembly cavity 1, a tail end of the housing gradually deforms and shrinks to be connected to the grip portion 2, and an annular protrusion 4 is disposed on an outer surface of the grip portion 2.
The inclined angle of the outer surface of the cavity wall of the assembly cavity 1 is preferably 1-3 degrees. Specifically, the inclination angle a of the upper and lower surfaces of the cavity wall of the assembly cavity 1 is 1 degree. The inclined angle b of the left side surface and the right side surface of the cavity wall of the assembly cavity 1 is 2 degrees.
The positions of the two sides of the inner wall of the shell corresponding to the annular bulges 4 are symmetrically and inwards sunken to form clamping positions 5, the clamping positions 5 are used for accommodating a convex part formed by overlapping and connecting the metal terminal and the electric wire, the assembly is tight, and the matching effect is good.
The inner diameter of the wire hole at the tail part of the shell is contracted to form a bayonet 6, so that the metal terminal can be prevented from withdrawing, the phenomenon that the shell is separated from the metal terminal during plugging is reduced, and the plugging process is convenient. In other embodiments, a transverse flange may be provided on the inner wall of the housing. The transverse flange has a triangular cross-sectional profile. The metal terminals are further prevented from being withdrawn from the housing by the lateral flanges pressing against the metal terminals. In addition, the inner wall of the shell is provided with an adhesive layer, so that the tightness of the assembly with the metal terminal can be improved, the phenomenon that the shell is separated from the metal terminal when the shell is plugged is avoided, and the plugging process is convenient.
When the socket is inserted, the outer surface of the cavity wall of the assembly cavity 1 gradually inclines towards the inner surface of the cavity wall from back to front to make the front end smaller in size, so that the socket can be conveniently and quickly aligned with the slot for inserting the socket.
When the assembly cavity is pulled out, the outer surface of the cavity wall of the assembly cavity 1 forms a certain gradient, so that the clamping force application of fingers is facilitated, and the slipping phenomenon is reduced. And when the assembly cavity 1 sinks into the slot of the socket or the cavity formed by other element devices, the holding part 2 can be directly clamped for insertion and assembly, and the annular bulge 4 is arranged on the outer surface of the holding part 2, so that the anti-skidding effect is achieved, the assembly and use requirements of different operations can be met, and the flexibility is high.
Variations and modifications to the above-described embodiments may become apparent to those skilled in the art from the disclosure and teachings of the above description. Therefore, the present invention is not limited to the above-mentioned embodiments, and any obvious modifications, replacements or variations made by those skilled in the art on the basis of the present invention belong to the protection scope of the present invention.
