Description

The power supply connector

The utility model relates to a kind of power supply connector, its for a kind of through repeatedly plug its be electrically connected reliable, the power supply connector that can come off because of vibration not.

Along with development of science and technology, palmtronic such as video camera, mobile phone and computer etc. are used for daily life and commerce in a large number, and wherein battery is the main power source of these equipment.But since these electronic equipments in use regular meeting vibrated; and power consumption is high; battery altering is quite frequent; therefore how the conducting terminal in the connector is cooperated with its housing is ingenious; guarantee under vibrational state, still closely to contact with battery, unlikely come off cause the outage, change repeatedly battery after; connector also can be kept good electrical connection, has become the important topic in present technique field.

A kind of existing power supply connector, as Taiwan patent application the 82nd, 103, the conducting terminal of No. 837 and the 5th, 470, No. 255 described wherein power connectors of United States Patent (USP) is one " ㄣ " shape structure, very easily because of with battery in corresponding connector terminal Long contact time compress and cause elastic fatigue, forfeiture should have contact force, causes disengaging, causes outage.In addition, the insulating body that is connected with this conducting terminal is not provided with desirable plug assembly, need spend more manpower and man-hour when therefore assembling, and improves assembly cost, reduces product competitiveness.

The purpose of this utility model is to provide a kind of power supply connector that is electrically connected with printed circuit board (PCB) that is suitable for, and it is through repeatedly still guaranteeing reliable electrical connection after the plug.

The purpose of this utility model is achieved in that promptly provides a kind of power supply connector, and it comprises an insulating body, and described insulating body one side forms a continuing surface, offers a plurality of slots on this continuing surface, is provided with an abutment face in slot; And a plurality of conducting terminals that are arranged in a plurality of slots of this insulating body and stretch out from insulating body one end.

The advantage of the utility model device is that it still can keep high flexibility after repeatedly changing battery, guarantee to contact with the tight of butt connector, and it is simple in structure, when shortening the assembler, save assembly cost, improves competitive power of product.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Fig. 5 is the utility model power supply connector conducting terminal stereogram, and the terminal material belt that links to each other with terminal is shown;

Fig. 6 removes the stereogram of strip with the connector conducting terminal for the utility model power supply;

Fig. 7 end view that to be the utility model power connector engage with the battery connector that docks.

See also Fig. 1 and Fig. 2, it is stereogram and the three-dimensional exploded view of the utility model power supply with connector.Power supply of the present utility model mainly comprises insulating body 10 and a plurality of conducting terminal 60 with connector.On the continuing surface 11 of this insulating body 10, offer a prescription and describe chamber 12 and a plurality of slot 13, accommodate the corresponding connector (not shown) of butt joint with it and the conducting terminal 60 of corresponding number respectively.These a plurality of slots 13 all are a strip conduit 14, the middle body of conduit 14 abutment face 15 that raises up, and extend a composition surface 16 by abutment face 15, a slotted hole crack 17 and a pair of hole 18 (as shown in Figures 3 and 4) that runs through are respectively offered in the both sides on this composition surface 16, composition surface 16 connects a kerve hole 19, and formation one can be accepted the strip conduit 14 of conducting terminal 60.In addition, partly be truncated into an inclined-plane 20 at these insulating body 10 back side apical margins, a plurality of strip conduits 14 the upper limb inner face be one forward and tiltedly stretch face 21 (as shown in Figure 7), and tiltedly stretch face 21 by this and extend one downwards and hang down by faces 22.In addition, set up a pair of buckling foot 31, can utilize the button hook 32 on it to be fastened on (not shown) on the printed circuit board (PCB) in the bottom side 30 of this insulating body 10.Be noted that, this is to buckling foot 31 and insulating body 10 one-body molded making, for obtaining should be flexible, axle center and button hook 32 places between this buckling foot 31, go out a rectangular perforation 33 by mould molding, when inserting it into the printed circuit board (PCB) location hole, this rectangular perforation 33 can easily be inserted in and combine closely with printed circuit board (PCB) buckling foot 31 for button hook 32 provides the space that can inwardly bounce back.

See also Fig. 5, the stereogram when it is connected with strip 65 with connector conducting terminal 60 for the utility model power supply.This conducting terminal 60 comprises from strip 65 and extends a holding parts 71 and be set at the pin portion 61 and the elastic portion 81 at these holding parts 71 two ends.This pin portion 61 is arranged on abreast from this holding parts 71 1 suitable distances after holding parts 71 is by a convergence part 62 bendings; Holding parts 71 forms a retaining sheet 72 and a pair of snapping sheet 73 perpendicular to terminal body behind two lateral bucklings of terminal body, and respectively establishes a hangnail 74 in the both sides of this retaining sheet 72, also establishes a clasp 75 in two outer rims of this make-up contact pin 73.Elastic portion 81 extends a contact site 83 by first butting section, 82 arcs that are connected holding parts 71 and second a hook-shaped butting section 84 is formed.

During assembling, the conducting terminal on the strip 60 can be plugged on a plurality of slots 13 of insulation shell 10 simultaneously, and by the holding parts on the conducting terminal 60 71 interfere and with slotted hole crack 17 slot 13 in and should be to running through hole 18 fastenings.At this moment, the pin portion 61 of this conducting terminal 60 can cover on the kerve hole 19 of insulating body 10, and stretch out outside the slot 13, first butting section 82 of conducting terminal 60 can be against on the abutment face 15 of insulating body 10, contact site 81 protrudes out outside the slot 13, so just finishes the assembling of the utility model power supply with connector.

See also Fig. 7, when the utility model power supply is electrically connected with the battery connector 90 that docks with connector, the part that first butting section 82 of conducting terminal 60 contacts with the abutment face 15 of insulating body 10 can move to the B point gradually by the A point, be that this arc elastic portion 81 fulcrum after stressed upwards moves and shortened the arm of force, thereby a preferable forward contact force is provided.In addition, 84 quilts are compressed to slot 13 when second butting section of conducting terminal 60, and contract and lean on when extremely hanging down by face 22, can provide stronger forward contact force to conducting terminal 60 again.Therefore, conducting terminal 60 can select for use the cheaper manufacture of materials of price to go out conformance with standard and competitive product.
