Above-mentioned purpose of the present utility model can be realized by following technical scheme:

A kind of battery connector includes insulating body, one group of conducting terminal and a pair of ground strip, the L-shaped shape of described insulating body, and an end of this conducting terminal forms elastic portion, and the other end of this conducting terminal forms weld part, it is characterized in that:

This insulating body is provided with the storage tank of planting for this conducting terminal, this conducting terminal storage tank has vertical component effect, insulating body has short leg and long leg, this vertical component effect runs through outer face in the insulating body short leg, and, has fin in each horn opening two side in short leg outer face formation horn opening; The connecting portion that has a bending between this conducting terminal elastic portion and weld part is provided with several arcuation sections in the connecting portion of this bending;

Be provided with insertion slot in the insulating body long leg, this ground strip is plugged in this insertion slot.

When the external force positive force increased, the utility model can reduce the terminal set deformation volume; Ground strip is " T " font, be arranged in the insulating body long leg insertion slot, interfere by ground strip stuck point and inserting groove inner arm face to reach fixing, is connected with circuit board then and reaches the connector strong fix simultaneously, so that the circuit electric connection to be provided by conducting terminal weld part and ground strip.

For making utility model purpose of the present utility model and architectural feature can further allow the person skilled in the art understand, accompanying drawing formula under it cooperates is further described the utility model with a specific embodiment.

[embodiment]

The specific embodiment of the utility model battery connector please be joined diagrammatic sketch 2 and shown in Figure 3, and this battery connector 50 is to be made of insulating body 1, one group of conducting terminal 2 and a pair of insulating body 1 two side ground strips 3 that are inserted in; Wherein this insulating body 1 is " L " type structure aspect, this insulating body 1 is provided with one group of terminal storage tank 13 for conducting terminal 2 plants, terminal storage tank 13 has " L " pattern sample with insulating body 1 same architectural feature, the vertical component effect 131 of these terminal storage tanks 13 runs through outer face in insulating body 1 short leg 11, and on short leg 11 outer faces, form horn-type opening 14, between each horn-type opening 14, be provided with export-oriented extended fin 15 on short leg 11 outer faces, these fins 15 prevent the excessive compression of battery in the time of can being butt battery contact-making surface, excessive and produce the overvoltage phenomenon to avoid producing pressure, influence terminal deformation and can not recover present situation, these terminal storage tank 13 horizontal parts 132 are located on the long leg 12 of insulating body 1, below terminal storage tank 13 horizontal parts 132, be provided with the holddown groove 16 of fixed conductive terminals 2, the insertion slot 17 that provides ground strip 3 to plant is provided in insulating body 1 long leg 12 2 sides, be in order to reach fixing with the interference of insertion slot inner arm face, to increase whole connector stability with ground strip 3 holding points 33.

Described conducting terminal 2 forms elastic portion 21 in an end of its each terminal, is provided with the arc length shape contact site 211 with the battery butt on elastic portion 21, respectively forms lug 212 foremost in this elastic portion 21 outside two sides; The other end in conducting terminal 2 forms a weld part 22 that is used to be welded on the circuit substrate, the connecting portion 23 that between elastic portion 21 and weld part 22, has bending, inwardly ring cutting has two place's arcuation sections 24,25 on the connecting portion 23 of this bending, elastic portion 21 tops can contact with terminal itself in the conducting terminal inside compression in 2 stressed backs, increased the effect of conducting terminal normal forces, because of arcuation section 24,25 has stronger compression resistance and recovery, can reduce the terminal set deformation volume; One fixed part 26 is arranged between weld part 22 and connecting portion 23 in addition.

The effect of ground strip 3 provides and forms firm engagement and frequency of utilization more between battery connector 50 and circuit board, its structure is comparatively simple, this ground strip 3 is by the moulding of sheet metal integrated punching, it is one " T " font, this ground strip 3 contains the welding foot 32 that a main body 31 and main body 31 outwards stretch out, and is shaped on stuck point 33 with insertion slot 17 interferences in main body 31 2 side blows.

Please refer to shown in Figure 4, it plants the utility model battery connector 50 one group of conducting terminal 2 from insulating body 1 conducting terminal storage tank 13, conducting terminal 2 elastic portion 21 are passed the loudspeaker opening 14 of conducting terminal storage tank 13 and are answered the battery butt outward, terminal fixed part 26 with reach firm after holddown groove 16 cooperates, a pair of ground strip 3 is plugged in the insertion slot 17 of insulating body 1 long leg 12, by ground strip 3 stuck points 33 and insertion slot 17 inner webs face firm engagement; Now please in conjunction with Fig. 5 and shown in Figure 6, be equipped with a fin 15 in each horn-type opening 14 2 side, but these fin 15 pressure limiting external force effects, as can be seen from Figure 6 terminal loading process situation, when connector 50 in not stressed, the terminal elastic portion outwards inclines to energetically, when stressed, conducting terminal elastic portion 211 is inwardly compression gradually, and when being applied to battery face and fin face and connecting, it is stressed to be maximum rating, this moment, the conducting terminal arcwall face was mutually concordant with fin 15 end faces, do not exist as fin 15, then external force also can continue to increase the then stressed excessive generation overvoltage phenomenon of terminal, it is restorative can not to reach original state, therefore, this fin 15 can be avoided battery connector 50 to produce the overvoltage phenomenon and cause drawback, helps improving the connector useful life.
