Description

Socket connector

[technical field]

The utility model relates to a kind of socket connector, especially a kind of socket connector of connecting with pin connector of being used for.

[background technology]

Prior art, can be with reference to No. 99239009.5, continent patent, this patent has disclosed a kind of electric connector combination, comprise socket connector and pin connector, socket connector includes insulating body, and it comprises main part, and on be formed with the butt joint space, prominent plate is from extending to main part in the butt joint space, and prominent plate upper and lower surface is provided with some through holes, to accommodate conducting terminal; Pin connector is provided with receiving space, to accommodate the prominent plate of socket connector, realizes electric connection between the two.

Yet, the defective of the prior art is: the edge of the end of prominent plate has corner angle, when pin connector is pegged graft with it, be difficult for pegging graft, and when pegging graft, be easy to wearing and tearing, the plastic material that comes off is brought to the top that is positioned at the conducting terminal on the prominent plate easily, influences the electric connection of conducting terminal on the conducting terminal of pin connector and the prominent plate.

Thereby, be necessary to design a kind of novel socket connector to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide the socket connector after a kind of improvement, is convenient to and the pin connector butt joint, and can guarantees electric connection preferably between the two.

For achieving the above object, the utility model socket connector comprises insulating body and is located in some signal terminals in the insulating body that insulating body is provided with prominent plate, and the end of prominent plate is provided with guidance part, and this guidance part roughly is the circular-arc of indent.

Compared with prior art, the guidance part of the prominent plate end of the utility model socket connector roughly is the circular-arc of indent, thereby be convenient to be connected with pin connector, it is laborsaving to peg graft, and in the connection procedure, prevent to be positioned on the conducting terminal because the wearing and tearing plastics come off, thus the electric connection of assurance socket connector and external plug connector.

[embodiment]

Below in conjunction with accompanying drawing the utility model socket connector is made and to be further described.

Referring to figs. 1 through Figure 10, the utility model socket connector comprises insulating body 1, signal terminal 2, power supply terminal 3 and metal shielding casing 4.

With reference to Fig. 3, Fig. 4 and Fig. 5, insulating body 1 comprises both side ends 11, and the main part 12 of this both side ends 11 of serial connection, and the lower surface of main part 12 is provided with two protuberances 120 that protrude downwards.The front surface of autonomous body 12 extends forward and is provided with prominent plate 13, and the upper surface of the plate 13 of should dashing forward is provided with the terminal containing slot 131 that several are through to main part 12 back sides, in order to accommodate corresponding signal terminal 2 in wherein, the terminal (not icon) that each signal terminal 2 can be corresponding with pin connector connects.Extension is provided with two projections 14 before both side ends 11 front surfaces, and the end of projection 14 stretches out and is provided with overhead kick 141, is formed with joint portion 142 between overhead kick 141 and the end 11.

The front end end of the lower surface of prominent plate 13 is provided with guidance part 132, and guidance part 132 roughly is circular-arc (being the outside that its how much centers of circle are positioned at guidance part 132) of indent, and the end of guidance part 132 stretches out and is provided with horizontal part 133, so that processing.Because of this guidance part 132 roughly is the circular-arc of indent, thereby make that the butt joint of this socket connector and pin connector is convenient and strength-saving, and the plastics of prominent plate 13 ends are not easy to wear, thereby can not influence the electric connection of signal terminal 2 with the terminal of pin connector of the terminal containing slot 131 that is positioned at prominent plate 13.

Both side ends 11 upper surfaces of insulating body 1 are respectively to having two conduits 111, to accommodate power supply terminal 3 respectively.

Metal shielding casing 4 comprises top 40, two side 41 and bottom 42, is formed with a receiving space 43, in order to prominent plate 13, main part 12 and the signal terminal 2 of accommodating insulating body 1, plays the effect of shielding signal terminal 2; 40 rear ends, top of metal shielding casing 4 are provided with two pressing parts 44, can cooperate closely with the main part 12 of insulating body 1; Bottom 42 is provided with two through holes 420, corresponding with the protuberance 120 on the main part 12 of insulating body 1, protuberance 120 can stretch into through hole 420, be interlocked together, in addition, stretch out respectively from 41 outsides, two side of metal shielding casing 4 and to be provided with hook portion 45, live the projection 14 of insulating body 1 in order to hook, combine with joint portion 142 and to be in the same place, and the terminal overhead kick 141 of projection 14 can prevent that the hook portion 45 of metal shielding casing 4 from moving up in front and back, break away from projection 14, thereby make metal shielding casing 4 and insulating body 1 fix firm.

Power supply terminal 3 comprises base portion 30, form weld part 31 from base portion 30 1 end horizontal-extendings, the contact site 32 that extends obliquely from base portion 30 other ends, the both sides of contact 32 extension downwards are provided with plate body 33, and these plate body 33 lower edges stretch out and are provided with supporting part 331, this supporting part 331 can be resisted against the roof (as shown in Figure 9) of the conduit 111 of insulating body 1, makes this power supply terminal 3 have certain precompression, to increase the elasticity of power supply terminal 3.

By implementing the utility model technological means, can be so that the butt joint of pin connector and socket connector, and the plastic material difficult drop-off of the prominent plate end of socket connector, thereby guarantee the signal terminal of socket connector and the good electric connection of pin connector terminal.
