Embodiment

For describing technology contents of the present utility model, structural feature, the purpose that is realized and effect in detail, give explanation below in conjunction with specific embodiment and conjunction with figs. are detailed.

See also Fig. 1, the utility model electric connector 100 comprises an insulating body 10, a housing 20 and several conducting terminals 30.

See also Fig. 2, insulating body 10 has a pedestal 11, and the front surface middle part of this pedestal 11 protrudes out a rectangular tabular substrate 12 forward, offers several terminals accepting groove 121 on the substrate 12.The both sides, rear surface of pedestal 11 have protruded out a projection 111 respectively backward, the upper surface front end both sides of pedestal 11 are concaved with a draw-in groove 13 respectively in pedestal 11 in projection 111 inboards, the both sides, upper surface rear end of pedestal 11 are concaved with a storage tank 112 respectively in pedestal 11 in projection 111 inboards.

Several conducting terminals 30 are immobilizated in the terminal containing slot 121 of insulating body 10 in the in-molded mode of one.

See also Fig. 2, Fig. 3 and Fig. 4, housing 20 has a upper wall 21 and reaches the two side 23 that links to each other with lower wall 22 with upper wall 21 with a lower wall 22, and described upper wall 21, lower wall 22 and two side 23 surround a receiving space 24.The outward-dipping respectively guidance part 25 that extended to form in upper wall 21, lower wall 22 and two side 23.Offer a perforate 231 that extends to lower wall 22 places on the two side 23 respectively, the edge of lower wall 22 in corresponding perforate 231 lower ends bends downwards respectively and extended to form one first pin 232, the inner surface that the outer surface of first pin 232 is provided with a ribs 2321, the first pins 232 is concaved with a groove 2322.This housing 20 offers an opening 211 in upper wall 21 trailing edge places, housing 20 extends back in opening 211 front ends and has been bent to form a retaining downwards and holds portion 212, retaining is held portion's 212 retainings and is held on the rear surface of insulating body 10, this retaining is held portion 212 and is inwardly offered breach 2121 in the bending part inboard, and retaining is held both sides, portion 212 lower end and extended to form one second pin 213 respectively downwards.Respectively to opening 211 inner bendings and extend to retaining and hold portion 212 and form an elastic arm 214, housing 20 extends to form a fixing arm 215 to opening 211 inner bendings respectively in the both side edges rear portion that abuts with two side 23 of opening 211 to housing 20 in the both side edges front portion that abuts with two side 23 of opening 211.

The connector of described guidance part 25 bootable butt joints (figure does not show) inserts.Described retaining is held breach 2121 that portion 212 offers and is reduced retaining hold the elastic-restoring force that portion 212 is produced when bending process, makes things convenient for bending process.Described two second pins 213 are held portion's 212 lower ends downward extension by retaining and are formed, and can guarantee that two second pins 213 are positioned at same perpendicular, are convenient to 213 alignment of two second pins, thereby make things convenient for electric connector 100 to be inserted on the printed circuit board (PCB) (figure does not show).Ribs 2321 that described first pin 232 increases in the bending part outside and the inboard groove 2322 that is arranged with, what can increase first pin 232 eats the tin area, makes welding more firm.

When this electric connector 100 of assembling, first pin 232 of housing 20 and the retaining hold portion 212 as yet the bending and be positioned at same plane with lower wall 22 and upper wall 21 respectively, insulating body 10 can be inserted the receiving space 24 of housing 20, elastic arm 214 holds and is contained in the draw-in groove 13, fixing arm 215 is coated on the projection 111, and fixing arm 215 front ends bendings is contained in the storage tank 112, again with tool downwards bending first pin 232 and retaining hold portion 212, thereby retaining is held portion 212 and is fastened on insulating body 10 rear surfaces.

In sum, the groove 2322 that the utility model electric connector 100 relies on first pin 232 to be arranged with in the bending part inboard, the metal material that the bending place squeezes out in the time of can accommodating bending process, to avoid metal material to be out of shape because of being squeezed when the bending process, and groove 2322 has reduced the thickness of bending part inboard, the outside has increased ribs 2321, thereby has reduced the elastic-restoring force that first pin 232 is produced when bending process, the bending difficulty when having reduced bending process.
