Description

Battery connector (three)

The utility model relates to a kind of battery connector, particularly a kind of battery connector structure that has in conjunction with the conducting terminal smooth and easy, that contact stabilization is better.

Battery connector is to be applied to being connected to each other between battery and electric device, especially be used in being connected of notebook computer and battery, and known battery connector usually as shown in Figure 1, have a pin connector 1 and a socket connector 2, be made by insulating material, can make pin connector 1 be fixed on the circuit board (as the motherboard of notebook computer) of electric device, this socket connector 2 then can be located at an end of battery relatively; Wherein, this pin connector 1 has the metal connecting terminal 11 of a plurality of spacing parallel arrangings, 2 of this socket connectors are provided with the corresponding slot 21 of a plurality of and this metal connecting terminal 11, and this slot 21 is formed by several dividing plate 22 spacing parallel arrangings, be embedded with a conducting terminal 23 in this dividing plate 22, use connecting when inserting, be connected with circuit between battery to finish electric device for the metal connecting terminal 11 of pin connector 1.

As shown in Figure 2, it is United States Patent (USP) a kind of battery connector structure that No. 5551883 patent application case disclosed, wherein, the shape of this conducting terminal 23 is by a body 231, one junction 232 and an elasticity arm 233 constitute, and this body 231 is in order to this conducting terminal 23 is fixed in the set storage tank 221 of this dividing plate 22, this junction 232 is extended by side after the body 231 and can expose to outside this socket connector 2, in order to link as these conducting terminal 23 external electrical, in addition, this elasticity arm 233 is by in the oblique space that extends into this slot 21, place, the contiguous base of side before this body 231, and form a contact site 234 that connects with above-mentioned splicing ear 11 at the end of this elasticity arm 233, the free end of this contact site 234 is more transferred and is suitable for being placed in the fixed part 235 of this storage tank 221 towards storage tank 221 extensions one of dividing plate 22, the state of its combination as shown in Figures 3 and 4, this conducting terminal 23 is inserted in the storage tank 221 of this dividing plate 22, utilize the holding piece that is convexly equipped with on the body 231 of conducting terminal 23 and this fixed part 235 and be positioned in this storage tank 221, and make this contact site 234 be positioned at the space of this slot 21, when treating splicing ear 11 these slots 21 of insertion of pin connector 1, then can make this splicing ear 11 form contact and be connected, and then make this pin connector 1 finish conductive bond with socket connector 2 with the contact site 234 of this conducting terminal 23.

Yet above-mentioned battery connector structure has following shortcoming on reality is used:

One. the positive force of contact is less, connection stability reduces relatively: as shown in Figure 2, because conducting terminal 23 is to utilize an elasticity arm 233 to extend forward to make behind the certain distance its contact site 234 to fall within the space of this slot 21 and close its front end place, be beneficial to contact with the splicing ear 11 of this pin connector 1 and be connected, so its textural genus one end is a stiff end, one end is free-ended cantilever design, and this contact site 234 is because of after being subjected to these splicing ear 11 compressing generation off normals, and then make this elasticity arm 233 produce a deflection angle A towards the wall of slot 21, make this elasticity arm 233 have the elastic force of a reinstatement, and form this contact site 234 and this splicing ear 11 between the two contact positive force, but its elasticity arm 233 is oblique extension (promptly extending along diagonal) on the one hand, so the stiff end of elasticity arm 233 and the physical length of free end are much larger than required length of extending forward, and contact site 234 is subjected under the also little situation of the mobile distance of splicing ear 11 extruding on the other hand, all allow 233 deflection angles that can produce of elasticity arm quite little, well imagine ground, its elasticity arm 233 is also quite small because of the elastic-restoring force that deflection produced, certainly its contact positive force is a corollary for a short time, therefore using with the passing of time or having the next contact site 234 that probably causes of slight external force collision can't keep contacting with the good of splicing ear 11, and then cause the situation of loose contact to take place, connector stable uncontrollable.

Two. in conjunction with the time easily form resistance and have some setbacks: the direction of insertion that enters slot 21 with splicing ear 11 ecto-entads of pin connector 1, elasticity arm 233 bearing of trends of this conducting terminal 23 be by after forward, just opposite with the direction of insertion of this splicing ear 11, so splicing ear 11 1 enters and will be subjected to contact site 234 that conducting terminal 23 protrudes from slot 21 behind the slot 21 and stop and produce a resistance, cause the perceptible blocking phenomenon of user and can't continue insertion, therefore the user must strengthen the application of force and could continue to push formation pin connector 1 and socket connector 2 having some setbacks on socket.

Three. termination contact partly is easy to wearing and tearing, useful life and reduces: since the contact site 234 of this conducting terminal 23 often and these splicing ear 11 generation resistances collide, not only the situation of these contact site 234 wearing and tearing more easily produces, and its strength will be passed to this body 231 via this elasticity arm 233, it is loosening that the location of the set storage tank 221 of this body 231 and this dividing plate 22 is produced, and causes reduce useful life.

Because the shortcoming that the positive force of the contact of above-mentioned known battery connector is little, combination has some setbacks, therefore, main purpose of the present utility model is to provide a kind of battery connector with conducting terminal of bigger contact positive force, to improve its connection stability.

A purpose more of the present utility model is to provide a kind of connection battery connector of conducting terminal comparatively smoothly that has.

Therefore, for reaching above-mentioned purpose, the utility model provides a kind of battery connector, it is characterized in that, this battery connector comprises: an insulation shell, have at least one terminal holding part, and this terminal holding part comprises one first slot and second slot that one of is connected with this first slot; And at least one conducting terminal, can be placed in this terminal holding part; This conducting terminal includes a body, a junction and at least one contact site, and wherein: this body is positioned in first slot of this insulation shell, has one first side and one of relative with this first side second side; This junction is extended away from this second side direction by first side direction of this body, can electrically connect in order to produce with a circuit board; And this at least one contact site is to become the extension of arcuation ground by second side direction of this body away from this first side direction, and can protrude in second slot of this insulation shell, can produce electric the contact with a terminal that is complementary.

Principal character of the present utility model is that the conducting terminal of this battery connector includes a body, a junction and a contact site; Wherein, this contact site is extended to form the flexible arc support arm of a tool in the arc mode by this body one side, this contact site can be protruded in the formed space of second slot of this insulation shell, and can produce electric the contact with a terminal that is complementary, and by warpage that this contact site produced, obtain bigger contact positive force, produce with the situation of effectively avoiding loose contact.

Another feature of the present utility model is that utilizing the contact site of this conducting terminal is an arcuation support arm, therefore can comply with the direction that conducting terminal is pegged graft, and then reduce resistance, promotes the smooth and easy of combination.
