Description

Battery connector

Technical field

The utility model relates to a kind of battery connector, is meant the battery connector that is electrically connected on the preinstalled circuit substrate for the button-type battery a kind of especially.

Background technology

Move towards light gradually at electronic product; thin; short; under the little epoch trend; also convergent is little to make the volume of various electronic product; and manufacturing at the inner various parts of electronic product; add processing procedure; also relative is more and more meticulousr; and must possess in the various electronic products printed circuit board (PCB) of electronic circuit for electronic component group setting position arranged; and printed circuit board (PCB) can be used for the motherboard on PC or the notebook computer; and on motherboard, can be equiped with the button-type battery usually; and described button-type battery is last; lower surface is respectively equipped with positive electrode and negative electrode; can provide motherboard as additional supply or accessory power supply; and utilize the less characteristic of its size, effectively to dwindle volume shared on the motherboard.

Yet, described button-type battery is to be fixed on battery connector inside, and be connected with motherboard by battery connector, and form firm location, see also Fig. 7, shown in Figure 8, be to be respectively existing three-dimensional exploded view and stereo appearance figure, find out by knowing among the figure, described existing battery connector is to comprise insulating body A, positive terminal B and negative terminal C form, wherein insulating body A is extended with two couples of retaining wall A11 at pedestal A1 side, A12, and at two couples of retaining wall A11, but form the space of set battery D in the A12, and positive terminal B and negative terminal C are electrically conducted respectively with battery D positive electrode and negative electrode, be that positive terminal B has the substrate B1 that can be installed in insulating body A, and substrate B1 is extended with the contact site B11 that can electrically conduct with battery D positive electrode, be extended with two button gripping arm B12 in contact site B11 one side again, then make and respectively detain gripping arm B12 and tilt with respect to battery D direction of insertion, to make things convenient for battery D to pack into, other makes the free terminal button of button gripping arm B12 be held in battery D, and bend outward in contact site B11 one side and to be extended with a pulling part B13, can utilize pulling part B13 will detain gripping arm B12 breaks away from battery D surface, and negative terminal C is respectively equipped with the elastic arm C1 of two bifurcateds, and all tilt to be upturned from pedestal A1, and be provided with the guiding access C11 that can electrically conduct with battery D negative electrode, C12, two guiding access C11, C12 vertically with laterally stagger mutually, and can electrically conduct with the negative electrode of battery D.But still there are many disappearances in aforesaid battery connector in use, and division is as follows now:

(1) its positive terminal B utilizes the two button gripping arm B12 of contact site B11 to detain respectively to be held on the battery D surface, and when battery D is influenced by external force, then breaks away from described two easily and detain gripping arm B12.

(2) its battery D desire is taken out when insulating body A, then need the application of force to pull the pulling part B13 of positive terminal B, and under long-term the use, the contact site B11 of described positive terminal B and substrate B1 turning point have the stress concentration phenomenon easily, also cause the turning point to produce slight crack or fracture.

In summary, above-listed every disappearance of existing battery connector is the direction place that the relevant manufacturer that is engaged in the industry desires most ardently the research improvement, and the dealer that remains to be correlated with makes further improvement and the necessity that redesigns.

Summary of the invention

Main purpose of the present utility model is: a kind of battery connector is provided, breaks away from pedestal because of influenced by external force to prevent default battery, and reach purpose firm, that locate really.

Secondary objective of the present utility model is: a kind of battery connector is provided, when default battery desire is changed or take out, only need press down on default battery surface, and its bottom is pressed on the set cantilever of second conducting terminal, impose the thrust of horizontal direction again, even default battery side pushing tow is at the set corresponding elastic arm of first conducting terminal, the default battery of confession can break away from first block at accommodation space, the restriction of second block, and the elastic restoring force by the set cantilever of second conducting terminal, can will preset battery and upspring, and simple and easy, take out in the pedestal outside fast.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of battery connector, it is characterized in that: be to include pedestal, first conducting terminal and second conducting terminal, wherein: described base interior is formed with the accommodation space that can accommodate default battery, and open area convexes with several first block that is relative formula and second blocks toward the inboard respectively above accommodation space, and between adjacent first block, be provided with the location division of tool clearance space, between adjacent second block, then be provided with limiting section away from the opposite side of location division; Described first conducting terminal is on the location division that is fixed between adjacent first block of pedestal, its tool base portion, and the base portion relative side is extended with the elastic arm that can stretch at the contiguous first stop location place of accommodation space and be relative flaring shape respectively outward, down bends in base portion one side and is extended with the inserted terminal that can supply to be welded on the preinstalled circuit substrate; Described second conducting terminal is on the limiting section that is fixed between adjacent second block of pedestal, its tool base portion, and base portion one side respectively up bending be extended with can stretch into inner and be skewed respective cantilevered at accommodation space, away from the opposite side of cantilever then down bending be extended with can be for the butt end that is welded on the preinstalled circuit substrate.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be:

(1) first block, second block that open area is convexly equipped with above its accommodation space, can distinguish block at default battery top surface, to limit the displacement of default battery vertical direction, the loosening or disengaging that can prevent to be produced when presetting battery is subjected to the external force vibrations is in the pedestal outside.

(2) elastic arm of its first conducting terminal can will be preset the battery levels pushing and pressing at accommodation space inner side edge wall, and being held in default battery bottom by the cantilever elastic top that adopts second conducting terminal, is first block, the second block inside of block at accommodation space but then make default battery.

When (three) its default battery desire is changed or is taken out, only need by being pressed in default battery surface, and impose the thrust of level, for default battery can break away from first block, the restriction of second block, and the elastic restoring force by the set cantilever of second conducting terminal, can will preset battery and upspring, and simple and easy, quick taking-up is in the pedestal outside.

(4) its default battery is to utilize one-body molded first block that is convexly equipped with in pedestal top, second block, limit the displacement of its vertical direction respectively, become and compare the bending, the type that utilize the positive terminal button to be held in battery surface to cause at existing battery connector, described first block, second block do not have the phenomenon that stress is concentrated, and can avoid producing slight crack or fracture yet.
