[execution mode]

Describe the embodiment and the manufacture method thereof of electric connector 1 of the present invention in detail below in conjunction with accompanying drawing.

See also Fig. 1 to shown in Figure 4, electric connector 1 of the present invention is used to electrically connect electronic component 5 to circuit board (not shown), and comprise metal shell 10, be immobilizated in the body 20 in the metal shell 10, and the flexible terminal 30 of injection moulding in body 20.

Metal shell 10, be to form by the metallic plate pressing and bending, integral body is the frame shape, comprise the first side wall 100 that is oppositely arranged, perpendicular to the first side wall 100 and with second sidewall 101 of the first side wall 100 adjacent settings, and the receiving space 102 that forms by the above-mentioned the first side wall 100 and second sidewall 101.Electronic component 5 just is contained in this receiving space 102, wherein the first side wall 100 comprises that three first support shell fragment 1000 and are positioned at the first side wall 100 position and the cross-notching 1001 that is provided with at interval on the lower side towards what receiving space 102 directions were extended, second sidewall 101 comprises that being arranged at that second of its middle part supports shell fragment 1010 and support shell fragment 1010 with second is the symmetrically arranged retaining sheet 1011 in center, on the above-mentioned the first side wall 100 and second sidewall 101 first supports shell fragment 1000 and second and supports the effect that shell fragment 1010 can play fixing electronic component 5 and ground connection is provided for electronic component 5, it is symmetrical arranged, can be to electronic component 5 fixing well.Retaining sheet 1011 on above-mentioned second sidewall 101 forms locker, with electronic component 5 reliably snap close in metal shell 10, the first side wall 100 and second sidewall, 101 free terminals also are provided with chamfering inclined-

plane

1002,1012, when assembling electronic component 5 in wherein the time, the effect of guiding is played in the assembling of these 1002,1012 pairs of electronic components 5 in chamfering inclined-plane.

Body 20 is made by insulating material, and integral body is a day font, comprises the crossbeam 201 on rectangular box-like main body 200 and connection main body 200 relative both sides.Wherein main body 200 and crossbeam 201 parallel one side are first side 2000, adjacent with first side 2000 is second side 2001, above-mentioned second side 2001 is provided with the projection 202 of being separated by and arranging, this projection 202 can cooperate with the fluting 1001 of metal shell 10, thereby is immobilizated in the metal shell 10.

Flexible terminal 30, injection moulding alternately is in body 20 crossbeams 201, comprise that injection moulding is in body 20 crossbeams 201 and the holding parts 300 of bending and the elastic arm 301 and the weld part 302 that extend respectively from holding parts 300 two ends, wherein elastic arm 301 and weld part 302 lay respectively at the both sides of crossbeam 201, and elastic arm 301 ends are provided with the contact jaw 3010 of arc, electrically to contact with electronic component 5.Flexible terminal 30 arranged crosswise, so the weld part 302 of adjacent flexible terminal 30 or elastic arm 301 lay respectively at the both sides of body 20 crossbeams 201, like this, mutual overlap joint and cause short circuit in the time of can avoiding flexible terminal 30 starts.

Here need to prove, because flexible terminal 30 is injection mo(u)ldings with body 20, so, flexible terminal 30 need be positioned when injection moulding in the mould (not shown), and flexible terminal 30 is led circular hole 31 diameters of a pin hole as diel in punching course generally bigger, in application-specific, if it can not be contained in the body 20 of day font, then flexible terminal 30 can be provided with location hole 32 between its weld part 302 and punching press circular hole 31 when producing.

Below in conjunction with shown in Figure 4, introduce the manufacture method of electric connector 1 of the present invention: at first that flexible terminal 30 punching presses are the required circle of position hole 31 of leading cuts, then flexible terminal 30 is placed alternately injection molding and be provided with on the mould of die cavity of day font, and its relative mould is fixed by the location hole on it 32, the plastic cement of fusion is cast in the mould, and its holding parts 300 at flexible terminal 30 is flowed, after the plastic cement of fusion solidifies, plastic cement in the mould forms the body 20 of day font, and body 20 and flexible terminal 30 reliable connection, wherein the plastic cement that flows in flexible terminal 30 holding parts 300 forms the crossbeam 201 of body 20, the plastic cement of other parts forms the main body 200 of body 20, cut away the location hole 32 of flexible terminal 30 this moment, then, the body 20 that will combine with flexible terminal 30 is assembled in the metal shell 10, during assembling, before metal shell 10 is bent into rectangle, the fluting 1001 on the wall of the 202 aligning metal shells of the projection on the limit of body 20 frame shape main bodys 200

second sides

2001,10 the first side walls 100 is not inserted, 10 one-tenth rectangles of bending metal shell then, make fluting 1001 on another walls of metal shell 10 the first side walls 100 accommodate projection 202 on body 20 main bodys 200 another second sides 2001, so far, body 20, flexible terminal 30, and metal shell 10 has fitted together, at last, electronic component 5 from top to down are placed in the receiving space 102 of metal shell 10, because metal shell 10 is provided with some first and supports shell fragment 1000 and second and support shell fragment 1010, so, when electronic component 5 places metal shell 10, these support shell fragment and are subjected to the extruding of electronic component 5 and strain takes place, and rely on himself elastic force and fixing electronic component 5 in metal shell 10, in like manner, electronic component 5 also can impose certain active force to the flexible terminal 30 of its bottom, flexible terminal 30 is owing to strain takes place the active force of electronic component 5, and electrically contact with electronic component 5, electrically conduct thereby reach.

Should be noted that, in the present embodiment, the body 20 of electric connector 1 of the present invention is owing to be a day font, therefore, it not only awards electronic component 5 support forces in the centre position, and also electronic component 5 is being produced certain supporting role all around, so, even assembling electronic component 5 overexerts in metal shell 10 time, this body 20 also can bear the pressure of electronic component 5 to it equably.

The above is a kind of execution mode for inventing only, it or not whole or unique execution mode, the variation of any equivalence that those of ordinary skills take technical solution of the present invention by reading specification of the present invention is claim of the present invention and contains.
