Description

Electric connector

Technical field

The utility model provides a kind of electric connector; When the docking section of finger insulating base frame is plugged in the socket especially; The clamping part at insulating base frame capable of using top is buckled for striding across the protruding of socket top with elastic arm; And be fastened in the catching groove that is an Openworks shape on the elastic arm by protruding button is corresponding, whole height is reduced and slimming person more.

Background technology

The fast development of electronics technology now; Make various electronic products such as computer, notebook computer and mobile phone, all be prevalent in each corner in the society, and because of various electronic products at present want all that cube is little, light weight, be easy to carry; To meet light, thin, short, the little design requirement of electronic product; And in order to make the volume-diminished of electronic product, so the structure of the spare part on the electronic product internal circuit board then needs small but excellent close; Overall construction intensity also needs to strengthen thereupon, with the development trend in response to present electronic product.

So; Traditional connector (like the connector of board to board connector, wire pair board connector or other patterns) has a public terminal adapter usually and a female terminal adapter cooperates butt joint; And public terminal adapter and female terminal adapter can supply cable to be arranged in it mostly; And do one with inner a plurality of signal terminals of connector or power supply terminal and be connected, can signal or power supply be sent in the control circuit through circuit board for another matching connector, see also shown in Figure 9; End view for public terminal adapter commonly used and female terminal adapter; Bodies top that wherein should mother's terminal adapter B is for being concaved with catching groove B1 towards the rear, and is provided with the fixing arm A1 that is hanging shape in the bodies top of public terminal adapter A, when public terminal adapter A is plugged in the slot of female terminal adapter B; Just can be fastened on downwards in the catching groove B1 of female terminal adapter B by the protruding button A11 of fixing arm A1 active side end, make public terminal adapter A and firm being combined into one of female terminal adapter B.

Fixing arm A1 that only should public affairs terminal adapter A is the place, catching groove B1 top that strides across in female terminal adapter B; And make that fixing arm A1 bottom is flat to be butted on the sidewall of catching groove B1 side edge; Come downwards to be fastened in the catching groove B1 by protruding button A11 again; The public terminal adapter A of this kind tends to receive the restriction on the space with the thickness that the height after female terminal adapter B cooperates need be added fixing arm A1, and whole height can't effectively reduce; In addition; In the process that public terminal adapter A pegs graft; Also can't be certain learn whether fully is pushed into the location, be easy to receive the influence of external force and the protruding button A11 tripping that causes fixing arm A1 in the restriction of catching groove B1, thereby causing public terminal adapter A to produce loosening situation takes place; Or and female terminal adapter B between electrically connect failure phenomenon, design effectively again and solve and remain to be engaged in this journey dealer.

Summary of the invention

So the creator is because problem and the disappearance that electric connector commonly used uses, to collect related data via assessing in many ways and consider, and utilize the research and development experience for many years of engaging in the industry constantly to study and revise, the beginning is designed the novel birth of this kind electric connector.

When the main purpose of the utility model is in the docking section of insulating base frame is plugged in the socket of presetting electric connector; The clamping part of its insulating base frame then presents softened state by protruding the buckling of the elastic arm ejection that is hanging shape in the socket top; And after treating that elastic arm strides across protruding button, just can be by making stable being inserted in the socket in docking section in the corresponding catching groove that is fastened on elastic arm of protruding button, this kind catching groove is the structural design that is an Openworks shape; Can supply socket protruding buckle to expose and be fastened in the catching groove locate; And can not receive the restriction in member shape or the assembling, and whole height is reduced and more slimming, to meet the compact design requirement of product.

The secondary objective of the utility model is in the process of insulating base frame insertion; The elastic arm of its clamping part just can be moved in the short slot at socket top; Can reduce the height that elastic arm takies; And by the supporting surface ejection at elastic arm leading edge bottom side place on the guiding incline at place, protruding button the place ahead, can present upwards softened state as fulcrum in the support portion after making elastic arm receive pushing of protruding button, and treat that the supporting surface of elastic arm strides across the guiding incline of buckling in protruding; Just can be by the elastic restoring force involution to original position; Protruding button correspondence is fastened in the catching groove on the elastic arm, and the inclined plane at catching groove interior sidewall surface place then block is located on the stopping surface of convergent in protruding button rear, and the increase docking section is plugged in the fixing strength in the socket and forms certain locating effect.

A kind of electric connector; Include insulating base frame and terminal group; Wherein: place, this insulating base frame the place ahead for be provided be plugged in the preset electric connector socket to a clamping part; And in clamping part one side place direction is extended with the elastic arm that is hanging shape towards the docking section, and cut open on the elastic arm surface and be provided with the protruding catching groove of buckle corresponding fastening that at least one supplies the socket top, then be formed with at least one support portion in clamping part again with the insulating base frame junction; This terminal group is to be positioned in the terminal groove of insulating base frame; And the base portion one side place of terminal group be provided be inserted in the docking section and with socket in the contact site that electrically contact of a plurality of conducting terminals of wearing, and base portion is provided with and presets cable and combine the junction surface of locating away from the side place in addition of contact site.

The utility model can make whole height reduce and more slimming, to meet the compact design requirement of product.
