Abstract

The utility model relates to an anti-released extended plastic case, which comprises a connecting seat, a terminal groove shell and a retaining clip, wherein the connecting seat and the terminal groove shell are formed by inserting two separate bodies through a junction pair, and the junction pair is formed by inserting and matching two convex strips and two grooves. One of the two grooves is a through groove, and the other groove is a blind groove. Convex shoulders are arranged at the top ends of the convex strips which are inserted and matched with the through groove, the top end of the through groove is provided with concave blocks, and the convex shoulders are inserted and matched with the concave blocks. The utility model has the advantages of simple structure, easy fabrication, low cost, no looseness, no release and no displacement, two parts are connected firmly and are tightly connected into one body, thereby, the optimal contact effect of an electric connector is ensured.

Description

The extendible shape shell of anti-slip

Technical field

The utility model relates to a kind of expansion shape shell of electric connector, i.e. the extendible shape shell of anti-slip.

Background technology

The expansion shape shell of present electric connector has two kinds: a kind of is that the composition surface is the plane, only pegs graft by four middle connection-pegs, this expansion shape shell structure complexity, though the cost height is not landing, but its composition surface is insecure, makes two perk and become like the seesaw; Another kind is to peg graft with groove by recessed, still, is easy to landing between raised line and the groove, and it directly influences result of use.

Summary of the invention

The utility model provides a kind of anti-slip extendible shape shell, and it is simple in structure, and bound fraction is firm, and is not loosening, can not produce the landing phenomenon, easy to use.

The utility model is achieved in that the extendible shape shell of a kind of anti-slip, comprise: Connection Block, terminal pot shell, geometrical clamp, described Connection Block and terminal pot shell are pegged graft by auxiliary connection by two splits and are formed, described auxiliary connection is pegged graft with two grooves by two raised lines and is cooperated, described two one of them grooves are logical groove, and another groove is blind groove, and the top of the raised line that cooperates with logical groove grafting is provided with convex shoulder, logical groove top is provided with scarce piece, and convex shoulder is pegged graft with scarce piece and cooperated.

The Connection Block of described each split and the affixed one of terminal pot shell, geometrical clamp is arranged on a side of its Connection Block.

The utility model is simple in structure, and is easily manufactured with low cost, the composition surface firmly, loosening, more can not slide, also avoid making as seesaw the generation of two perk phenomenon, it makes two parts strong bonded as a whole, thereby has improved the contact effect of the binding of electric connector.

Fig. 2 is two split connection status of the utility model schematic diagram.

Fig. 3 is that the utility model A is to schematic diagram.

Embodiment

Elaborate with description of drawings in conjunction with the embodiments:

Embodiment: the extendible shape shell of anti-slip, as Figure 1-3: the extendible shape shell of a kind of anti-slip, comprise: Connection Block 1, terminal pot shell 2, geometrical clamp 3, described Connection Block 1 and terminal pot shell 2 are formed by being connected to 4 grafting by two splits, described auxiliary connection 4 is by two raised lines 406,403 and two grooves 402,401 peg graft cooperates, described two one of them grooves 402 are logical groove, another groove 401 is blind groove, the raised line 406 that cooperates with logical groove 402 grafting) top is provided with convex shoulder 404, logical groove 402 tops are provided with and lack piece 405, and convex shoulder 404 is pegged graft with scarce piece 405 and cooperated.

The Connection Block 1 and the terminal pot shell 2 affixed one of described each split, geometrical clamp 3 is arranged on a side of its Connection Block 1.

Described Connection Block 1, pot shell 2 and geometrical clamp 3 adopt ambroin.

In use, it is a firm integral body that two splits are pegged graft by auxiliary connection, its contact-making surface is a complete face, under the effect of blind groove and convex shoulder 404, prevent two not landings of split, unshift, also avoid making as seesaw the generation of two perk phenomenon, it makes two parts strong bonded as a whole, has ensured the best contact effect of electric connector.

Experimental results show that: the utility model is simple in structure, and is easily manufactured, with low cost, and two parts engage firmly, not loosening, not landing, and unshift, it is as a whole that fluid-tight engagement becomes, thereby ensured the best contact effect of electric connector.
