Description

Connector grounding elastic part structure

Affiliated technical field

The utility model provides a kind of connector grounding elastic part structure, especially a kind of free-standing grounding elastic part structure with ground connection and connection-peg correcting function when inserting.

Background technology

Existing stacked electric connector, for better signal laser propagation effect is provided, eliminate electromagnetic interference (EMI), the capital coats the shielding casing of a metal material at the skin of connector, simultaneously for also to keep excellent contact with connection-peg, therefore on connector body, can be provided with contact flat spring, and prior USB, the IEEE1394 connector, because of promptly being provided with the shell fragment of seizing connection-peg on both sides by the arms on the clad metal shell, needn't set up grounding elastic part more in addition, but connector with big interface, especially on the socket connector of network connector RJ series, often be contact flat spring to be set, make connection-peg more stable when pegging graft at side, simultaneously also utilize contact flat spring, to eliminate electromagnetic interference as ground connection.

The structure of side contact flat spring in existing connector, as Fig. 6, shown in 7, these graphic disclosed electric connector contact flat springs 52 are to be arranged on the procapsid 51, directly extending bending by its procapsid 51 forms, though it is comparatively convenient to have on processing procedure, assembling is easy to advantage, but because of contact flat spring 52 must possess better elastic and fatigue resistance, anti-plug and be difficult for the requirement of deformation, normally correcting when connection-peg inserts, ground connection, so having relatively high expectations of material, but because of contact flat spring 52 and housing 51 are formed in one, it is not difficult to find the defective that this structure exists: the material of contact flat spring 52 is subjected to the restriction of housing, can't change, can't promote the elasticity and the fatigue resistance of contact flat spring 52.

Also have this structure when punch forming, also need set up Mould Machining workshop section, increase mould development, manufacturing expense; Whole punch forming is because of the variation of rapidoprint hardness, and there is great influence in service efficiency, life-span of mould.

Therefore, at the existing defective of above-mentioned electric connector, be necessary existing technology is carried out design improved in fact, with the electric connector grounding elastic part structure that a kind of superior performance is provided, can reduces cost again.

Summary of the invention

Main purpose of the present utility model is to provide a kind of connector grounding elastic part structure, grounding elastic part is a stand-alone configuration, be arranged with the housing branch, holding is on the connector two side, can make the material of grounding elastic part select the preferable synthetic metal of elasticity by this structure, the performance of product also is much improved.

Above-mentioned all purposes of the present utility model can be realized by following technical scheme: this electric connector is to comprise parts such as connector modules, shielding casing, grounding elastic part; Wherein shielding casing is divided into procapsid and back casing two parts composition; This grounding elastic part is designed to absolute construction, be bent to form the inlay card sheet by the extension of main part top, fixed on the two side of connector with the holding of inlay card sheet, the inlay card sheet forms trapezoidal portion, be beneficial to it and insert the embedding hole, in addition on the side of inlay card sheet, also be provided with protruding head part, form interference effect after making the inlay card sheet insert the embedding hole, help the grounding elastic part fixing and be positioned on the connector sidewall; The both sides of this grounding elastic part main part then are bent to form flexible abutting part, form elastic arm, so that against connection-peg and back casing; Because conflict on housing in the end of the elastic arm of grounding elastic part, produce the ground connection effect of frequently covering, when connection-peg inserts, the side end in addition of grounding elastic part inwardly elasticity conflict simultaneously on the sidewall, can import connection-peg smoothly, the connection-peg of end contact simultaneously conducting ground connection so makes these grounding elastic parts except that having grounding function, can also insert by the correcting connection-peg.

For the personnel that utility model purpose of the present utility model and architectural feature can further be allowed be familiar with this technology understand, cooperate now appended graphic, with a specific embodiment to the utility model further instruction.
