Embodiment
Please refer to shown in Fig. 1 to Fig. 4, the electric connector of the utility model preferred embodiment, it comprises insulating body 1 and a plurality of terminal 2 be made of metal.This electric connector can be applicable to battery connector, electronic card coupler etc.
Insulating body 1 has interface 1a, the solder side 1b relative with interface 1a and a plurality of terminal groove 11.Terminal groove 11 is all positioned at the same side of insulating body 1, each terminal 2 of the accommodating correspondence of each terminal groove 11, therefore the electric connector of the present embodiment is the electric connector of the single setting of a kind of terminal.There is above terminal groove 11 opening 12, interface 1a is communicated with opening 12 with terminal groove 11, the part being placed in the terminal 2 of terminal groove 11 stretches out interface 1a to engage with butt-jointed electric connector (not illustrating) terminal from opening 12, therefore the electric connector of the present embodiment is a kind of terminal exposes and the electric connector of single setting.Two opposite side walls 13 bottom of terminal groove 11 is respectively arranged with guide groove 14 along side wall length direction, and the top, two side 13 of terminal groove 11 is respectively convexly equipped with shoulder 15 along side wall length direction.
Terminal 2, as shown in Figure 4, have base portion 21, from base portion 21 rear end 21b upwards circular arc is bent to form backward elastic portion 22, own elasticity portion 22 front end 22a turn forward after extending forward upwards bend the kink 23 extended to form, the contact site 24 be bent to form from the downward circular arc of kink 23 front end 23a, from contact site 24 front end 24a tilt backwards extend downward base portion 21 top position after the butting section 25 that is bent to form backward again and the leg portion 26 be connected with base portion 21 front end 21a.In the present embodiment, elastic portion 22 first to tilt backwards after downward-extension more upwards circular arc from base portion 21 rear end 21b and is bent to form, and makes base portion 21 present bending structure with the junction of elastic portion 22.Elastic portion 22 can be compressed with elasticity, and kink 23 also can provide elasticity.
The limit, two opposite sides of the base portion 21 of terminal 2 respectively extends to form alar part 27, and each alar part of mat 27 embeds each guide groove 14, and terminal 2 is positioned terminal groove 11.In the present embodiment, the alar part 27 of each terminal 2 forms two pairs of holding sections 271 to tear molding mode, and mat each holding section 271 correspondence fastens in each guide groove 14, and terminal 2 is positioned terminal groove 11.Holding section 271 can strengthen alar part 27 embed guide groove 14 after confining force, to ensure that terminal 2 is positioned the stability of terminal groove 11; And guide groove 14 can be made highly to increase, allowing can be thicker for the die forming guide groove 14 on insulating body 1, convenient processing and shaping, and the die life-span is longer.Such as, but the present embodiment is also not used to limit the present invention, alar part front end upwards can be bent to form holding section to turn forward at angle with base portion.In addition, the contact site 24 of terminal 2 can be provided with convex closure 241, to increase engagement capacity and the conductive capability of contact site 24 and butt-jointed electric connector terminal, avoid loose contact to occur, make Signal transmissions more stable.
The limit, two opposite sides of the butting section 25 of terminal 2 respectively extends to form lug 251, the lower edge 151 that each lug 251 is resisted against corresponding each shoulder 15 produces position-limiting action, and the height stretching out the contact site 24 of interface 1a after making terminal 2 be positioned terminal groove 11 from opening 12 is consistent.In addition, the connecting bending folding part, contact site 24 one end 23 of terminal 2, the other end connects butting section 25, and the free end 252 of butting section 25 is positioned at base portion 21 top position, therefore, when the electric connector terminal 2 of the present embodiment engages with butt-jointed electric connector terminal, the free end 252 of butting section 25 abuts base portion 21, can positive force be increased and make joint more stable, and terminal can be made comparatively can not permanent deformation to occur and follow the string.
Terminal 2, as shown in Figure 3, its leg portion 26 can adopt surface mount technology (Surface Mount Technology, SMT), therefore leg portion 26 bends downwards from base portion 21 front end 21a and extends to form forward, and molding mode can be torn formed, while guarantee solder area, to save terminal sheet material.Now, have soldering opening 16 below terminal groove 11, solder side 1b is communicated with soldering opening 16 with terminal groove 11, and the leg portion 26 being placed in the SMT pattern of the terminal 2 of terminal groove 11 can be positioned at soldering opening 16 to be welded in circuit board (not illustrating).
In the present embodiment, another side that insulating body 1 is relative with the side being provided with terminal groove 11 is extensible is provided with trapezium structure 17, can increase the absorption area of the suction nozzle for extracting elements, meet different nozzle structure.The solder side 1b of insulating body 1 can be provided with reference column 18, can ensure there is good location on circuit boards.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little change and retouching, therefore protection range of the present utility model is when being as the criterion depending on the appended claim person of defining.
