Description

The connector improvement structure

Technical field

The utility model relates to the connector improvement structure, is meant a kind of simple structure, with low cost and convenient, the good connector construction of anti electromagnetic wave interference effect of assembling especially.

Background technology

Common related connector structures such as USB, just like No. 491422 (applying for No. 90201186) patent case of TaiWan, China patent gazette, it is to be a metal shell with a complete sheet metal forming, for a periphery that is coated on an insulating base, yet, because the shape of insulating base, complex structure, make this metal shell be difficult to merely be coated on the appearance side of insulating base in the fit mode, stretch into the location and must reserve bigger opening in half-formed mode earlier for insulating base, continue the uncompleted bending of metal shell again, and be held in relative position on the insulating base with the hook sheet hook of reserving, so that the two is able in conjunction with fixing; This kind structure, integrated metal shell not only shape are complicated, and exploitation degree of difficulty height, production cost are also higher, and its insulating base, metal shell are after production is finished respectively, still need can finish assembling with tool processing bending in when assembling, time-consuming bothersome, the utmost point does not meet economic benefit.

Disclosed just like No. 476459 (applying for No. 89220647) patent case of TaiWan, China patent gazette in addition, though it is the different parts that is coated on insulating body with two shields (metal-back) that separate respectively, and by the mode of relative concavo-convex position inlay card in conjunction with the location, but by its Fig. 3 and shown in Figure 8, its secondary shielding body is still in half-finished mode and begins assembling, fully difficulty is taken off the assembling aspect of " continuing the uncompleted bending of metal shell when assembling; and be held in relative position on the insulating base with the hook sheet hook of reserving ... ", therefore, also there is assembling time-consuming bothersome unavoidably, do not meet the shortcoming of economic benefit.

Summary of the invention

The utility model aims to provide a kind of connector improvement structure, it mainly is two sides that are sheathed on body with the sidepiece of a shell two sides by the place ahead, and utilize a plurality of corresponding shell fragments and projection to produce and replace the location, the top of body then covers with the loam cake of the vertical kink of a tool, kink two sides of this loam cake and being provided with bend inwards and the side flanging of tool hollow hole, evagination shell fragment with absolute presupposition on the sidepiece of this hollow hole fit shell, the location division of absolute presupposition on the sidepiece of the Location resilient piece embedding shell of cooperation loam cake two side evaginations, can make shell, loam cake is complete and be coated on the body outer peripheral edges closely, to reach best anti electromagnetic wave interference effect, this is a main purpose of the present utility model.

This kind connector improvement structure of the present utility model, between its body, shell and the loam cake, all be the projection with the mutual slide guide of tool, protruding shell fragment and the mutual inlay card of hole and locate, very convenient in its assembling, fast, be convenient to a large amount of productions fast, this is another purpose of the present utility model.

This kind connector improvement structure of the present utility model, its each element not only itself is constructed simple and easy, and the mould of its production also has simple in structure, cheap characteristics, not only can effectively reduce production costs, also can shorten the exploitation time-histories, increase product competitiveness, this is a purpose more of the present utility model.

As for detailed construction of the present utility model, application principle, effect and effect, then the explanation of doing with reference to following adjoint can be understood completely.
