Described insulation shell 30 offers the contact installation cavity 35 that is used to assemble described power supply contact 40 of its front and back end of a plurality of perforations, and each contact installation cavity 35 is set up in parallel about on the length direction of electric connector.Be provided with the open slot 31 that communicates with contact installation cavity rear portion in each contact installation cavity 35 rear portion on insulation shell 30 bottom surfaces, the termination pin 5 that open slot 31 can hold power supply contact 40 is inserted and is worn and expose, and is provided with the radiating groove 32 that communicates with contact installation cavity rear portion in each contact installation cavity 35 rear portion on insulation shell 30 end faces.Leave the heat-dissipating space that is used for air flows between two surface plates 1 of two contact chips 20,21 of described power supply contact 40, described radiating groove 32 is relatively arranged on the heat-dissipating space both sides with open slot 31, and heat can be discharged through heat-dissipating space from circuit board.Be provided with two pairs of guiding mounting grooves that are used for the surface plate 1 of the described contact chip of front and back guiding inserting relatively on the close electric connector top of each contact installation cavity 35, the cell wall of both sides, bottom surface, in Fig. 7, be shown as the guiding mounting groove 33 of a pair of bottom side on the right, the guiding mounting groove 34 of top side.Described open slot 31 rear ends pass to the electric connector rear end and have backwards the trough wall surface 37 that cooperates with block protuberance 4 blocks on the contact chip of being used for.The chamber wall of each contact installation cavity 35 left and right sides be provided with contact chip on the elasticity hangnail 9 card draw-in groove 36 of joining, the oral area that this draw-in groove 36 is in the electric connector front end from contact installation cavity 35 extands rearward to the middle part of contact installation cavity chamber wall, the cell wall of draw-in groove 36 rear ends on the wall of contact installation cavity chamber, form forward, be used for the step surface 361 that cooperates with the terminal block of the elasticity hangnail of power supply contact.Also be provided with on the chamber wall of the contact installation cavity 35 at described draw-in groove 36 places and be in described step surface 361 reinforcing boss 39 afterwards, reinforcing boss 39 front ends have the additional block end face 391 that flushes with described step surface 361 forward, in the embodiment 1 of electric connector, it is domatic that the rearward end of this reinforcing boss 39 has the decline that extends back, and the chamber wall of contact installation cavity 35 has the wall that is lower than reinforcing boss 39 after reinforcing boss 39 rear ends.The structure of above-described insulation shell is the embodiment 1 of insulation shell of the present utility model simultaneously.
The process of the contact installation cavity 35 from rear end (inserted terminal the is a front end) insulation shell of packing into of insulation shell 30 of the contact chip in the foregoing description: the tongue piece of contact chip is introduced into the contact installation cavity, the surface plate 1 wideer than tongue piece inserts guiding mounting groove 33,34, the elasticity hangnail 9 of contact chip is subjected to the external force contraction and enters in the draw-in groove 36, elasticity hangnail 9 opens under the elastic deformation effect of self, the step surface forward 361 that the end of elasticity hangnail 9 withstands draw-in groove 36 stops contact chip to move backward, the trough wall surface backwards 37 that block protuberance 4 on the contact chip withstands open slot 31 stops contact chip to move forward, contact chip is locked at fore-and-aft direction, and product is in place.What need replenish is, in other embodiment of the present utility model, the location structure that stops contact to move forward is not limited to the cooperating of trough wall surface 37 on block protuberance 4 and the insulation shell 30 on the contact in the foregoing description, also can adopt the block mating surface that is provided with on other positions are convexly equipped with on the contact chip protuberance and contact installation cavity inside or the collar extension to cooperate, or utilize the structrural build up step surface forward that is in after the tongue piece of contact chip itself to cooperate with the step surface of contact installation cavity inside and forms the block cooperation that stops contact to move forward, such as the block cooperation of the shutoff face of corresponding setting in the front end face that can utilize surface plate 1 and the mounting groove that leads.
When electrical connector plug of the present utility model and adaptive socket plug together, the tongue piece 11 of two contact chips is introduced in the jack of adaptive socket contact, because the outside perk of the outer flap section 112 of tongue piece 11, make the width of the width dimensions of two contact chips greater than jack, so tongue piece 11 inwardly shrinks, the socket surfaces that elastically-deformable tongue piece 11 compresses the socket contact takes place, back support convex 7 on two contact chips is adjacent to and is abutted together simultaneously, with the surface plate 1 of contact chip being pressed on the insulation shell 30 tightly, surface plate on two contact chips is separated from each other, stop two surface plates to be fitted, the mutual fulcrum that bending is provided for two tongue pieces, 11 roots that supports of two preceding support convex 12 on two contact chips, guarantee that tongue piece 11 contacts with jack reliably, and make the inside contraction deformation of tongue piece 11 can not reach the contact chip rear portion, thereby avoided elasticity hangnail 9 from the draw-in groove 36 of insulation shell, to deviate from; Support convex 12 also plays the effect that strut relative two surface plates 1 identical with back support convex 7 simultaneously.
In the embodiment of above-mentioned electric connector; the power supply contact is that two contact chips divide body structure; and the main innovation of the claimed technical scheme of the utility model is the reinforcing boss structure of insulator draw-in groove; therefore in other electric connector embodiment of the utility model; also can adopt the contact that connects by bridging structure as two contact chips of the prior art, the power supply contact both can be that public contact also can female contact.
The embodiment 2 of electric connector of the present utility model, shown in Figure 12～13, be with the difference of embodiment 1, reinforcing boss 69 in the insulation shell forms the long convex tendon of length from the rear end that described step surface 361 extands rearward to the contact installation cavity, and the structure of the insulation shell among the embodiment 2 of above-described electric connector is the embodiment 2 of insulation shell of the present utility model simultaneously.
