Abstract

The utility model provides a settlement-plate-type electrical connector. The connector includes an insulating base, multiple electrical terminals held in the insulating base, and a rectangular metal housing sheathing the insulating base, wherein positioning mechanisms are provided in parallel transversally on the rear end surface of a terminal supporting base of the insulating base. At least two elastic sheets horizontally extend outwards from two side surfaces of the metal housing in parallel, and each elastic sheet is bent downwards to form a pin parallel to its side surface. The connector can be mounted on a slot circuit board through the positioning mechanisms and the pins, thereby lowering altitude of the connector and saving space.

Description

Heavy board-like electric connector

Technical field

The utility model provides a kind of heavy board-like electric connector, especially relates to a kind of USB (universal serial bus) electric connector and uses.

Background technology

USB (Universal series Bus, USB) electric connector has the dissimilar signal I/O functions of adjustment, USB connector is a kind of active data transmission one of electric connector comparatively widely that is used for, (as: scanner in computer fittings field and interface equipment, digital camera, storage electron-like interface equipments such as keyboard) all be to adopt the USB electric connector as the transfer connector interface, as shown in Figure 1, it is a kind of existing and USB electric connector of using, these electric connector 50 inserting foots directly extend from hull outside, when circuit board 60 engages, height in the time of can not reducing the connector use, himself structural form is huge and take sizable space of electronic product, strengthened the electronic product profile undoubtedly, this and existing electronic product are light, thin, short and small development trend is disagreed, necessary existing USB (universal serial bus) electric connector is transformed, to satisfy the demand.

Summary of the invention

Main purpose of the present utility model is to provide a kind of heavy board-like electric connector, especially relates to a kind of USB (universal serial bus) electric connector and uses.

Be to realize the purpose of this utility model, it adopts following technical scheme to be realized: this heavy board-like electric connector system by insulating base frame, be contained in several electric terminals in the insulating base frame and the metal shell that is sleeved on the insulating base frame is constituted; Wherein insulating base frame has a terminal stacker, be connected in the groove that front surface offers at least one and metal shell holding in terminal stacker upper and lower surface, on terminal stacker front surface, stretch out the contact site that is connected in butt connector forward, respectively prolong outstanding support arm along terminal stacker two side faces backward on the other end corresponding with it, a cylindrical reference column is extended down to and stretches in each support arm lower surface; A plurality of electric terminals are plugged in the insulating base frame, the rectangular style of metal shell, be provided with the portion of pulling that supports that at least one engages with the insulating base frame groove in these metal shell first and second surperficial rear ends, reach insulating base frame and metal shell strong bonded, be connected in metal shell first, the two side faces of second surface from each lateral longitudinal at least two shell fragments of outside horizontal Zhang Shenkai, the downward bending of its each shell fragment goes out the inserting foot that parallels with side separately, connector is installed in the circuit board with open slot, the horizontal ends holder of shell fragment is attached on the circuit board to keep level, its whole connector lower part of the body is in circuit board open slot below, positioning cylinder by connector and shell fragment inserting foot are with connector and circuit board strong bonded, reduce connector use height thereby reach, save the mechanism space.

Be familiar with this technical staff and can understand structural feature of the present utility model really for making, and the utility model purpose and effect, lift a specific embodiment now, conjunction with figs. is described in detail.

Embodiment

See also shown in Figure 2ly, be heavy board-like electric connector one specific embodiment of the utility model, this heavy board-like electric connector 100 is made up of an insulating base frame 1, a plurality of electric terminal 2 and the metal shell 3 that is sleeved on insulating base frame 1 periphery; Now in conjunction with Fig. 3 and structure shown in Figure 4 this heavy board-like electric connector 100 is done a detailed description in the lump, wherein insulating base frame 1 has a terminal stacker 11, in terminal stacker 11 upper and lower surfaces and be connected in the recessed groove 12 that fixes for metal shell 3 that is provided with of front surface, 13, be positioned at groove 13 rear ends at terminal stacker 11 lower surfaces and be provided with yielding groove 14, it is outstanding for the contact site 15 that is connected with the conducting of butt joint electric connector to stretch out in terminal stacker 11 front surfaces, outstanding support arm 16 is respectively prolonged along terminal stacker 11 two side faces in another surface relative with terminal stacker 11 front surfaces, be provided with the cylinder 161 that is positioned circuit board in each support arm 16 lower surface, offer open groove 17 at terminal stacker 11 rear end faces, be concaved with through hole 18 power supply property terminals, 2 plants and extend to contact site 15 formation grooves 181 along through hole in these groove 17 end faces.

Electric terminal 2 inserts from insulating base frame 1 rear end through hole 18 and closes in the groove 181, and its each electric terminal 2 includes a fixed part 21, extends to form welding ends 23 in fixed part 21 1 ends, is extended down in its other end to form contact jaw 22 and and form one and choose portion 24.

Metal shell 3 nationalitys are by the moulding of metal metal plate body integrated punching, this metal shell 3 is by first surface 31, second surface 32 and be connected in the rectangular configuration style that first, second surperficial two side faces 33 is enclosed, respectively be provided with in first surface 31 and second surface 32 rear ends with supporting of fastening of insulating base frame 1

groove

12,13 and pull portion 311,321, reach the two strong bonded; Be connected in first, second surperficial two side faces 33 outside at least two shell fragments of Zhang Shenkai 34 on each side, its each shell fragment 34 downward bendings go out with side separately to parallel inserting foot 342,341 bearings of horizontal ends can be put down whole connector holder on circuit board on circuit board.

The utility model sinks board-like electric connector 100, the combining structure of itself and circuit board 4 sees also shown in Figure 5, earlier electric terminal 2 is inserted in the groove 181 from insulating base frame 1 rear end through hole 18, reach fixing by terminal fixed part 21 and insulating base frame 1, again the product that combines is enclosed within on the metal shell 3, to assemble perfect good electric connector 100 afterwards is placed in the circuit board 4 with open slot, cooperate with circuit board 4 each corresponding positioning round orifice and jack by insulating base frame 1 rear end positioning cylinder 161 and metal shell 3 inserting foots 342 and to reach connector and fix, as shown in Figure 6, the lower part of the body of connector 100 is sunken to the below of circuit board 4 open slots.With existing and electric connector that use is compared, the utility model effectively reduces product and uses height, can save electronic product mechanism space, reaches the purpose of dwindling the electronic product volume.
