The volume of the utility model is small, the density of the contact couple is high, but the basic performance of the connector is not influenced, the contact pin recessed in the casing body is not easy to be collided, the angle among five guidance keys can be changed from 90 degrees to 270 degrees, the inserting and the pulling of the electrical connector are actuate and rapid, the line clocking body, the seal ring and the interface seal body ensures that the connector works normally under the water condition.

Description

Small circular line spring hole electric connector

Technical field: the utility model relates to a kind of small circular line spring hole electric connector that is used for electric equipment and the transmission of testing equipment signal.

Background technology: mispluging of electric connector can cause burning of electric equipment, at present, be widely used in the round wire spring hole electric connector on the electric equipment, because the contact of connector idol is almost concordant with the end face of its housing, so when plug plug or socket, once plug or socket tilt, or shell is run into contact pin, just can cause the generation of accident, owing to the external diameter Φ=1.8mm in line spring hole, hole wall is 0.2mm again.The density of the contact idol of electric connector has been limited in the line spring hole of this dimensional structure, diameter of its contact idol and contact idol with contact between the idol apart from bigger, make that the overall dimensions of electric connector are bigger, volume is heaviness.

Summary of the invention: cover attack contact pin during for fear of the plug electric connector, improve the waterproof of electric connector, anti-oblique cutting, the anti-mis-insertion performance, reduce the overall dimension of electric connector, the utility model is made up of plug and socket two parts, the end face of socket is provided with five feather keys being made up of a major key (groove) and four auxilliary keys (groove), jack is a wire spring socket, outside dimension Φ=the 1.7mm in line spring hole, wall thickness is reduced into 0.15mm, the contact idol is 2.4～2.6mm with the spacing that contacts between the idol, the quantity of contact idol is 7～129, and the head of contact pin is recessed into housing end face 6～9mm, and the anterior outer rim of Socket casing is embedded with three bails, three curved grooves are arranged on the inner edge of the coupling nut of plug, the tail end of plug and socket is equipped with grommet, and the socket head is equipped with sealing ring, and pin head is equipped with the interface sealing body.Because the spacing of dwindling and contacting between idol of the outside dimension in line spring hole and wall thickness reduces, make the volume of connector significantly reduce, the recessed housing of contact idol makes contact pin be difficult for being collided, and the anti-oblique cutting of realization, the grafting of plug and socket has been adopted five key positions guiding multi-angle to change and has been plugged together, it can change between 90 °～270 °, electric connector is being inserted, simple to operate when pulling out, peg graft accurately, prevent to misplug, three curved groove bayonet sockets make plug, socket connects and separates fast, the plug and socket afterbody is equipped with grommet, the socket head is equipped with sealing ring, and pin head is equipped with the interface sealing body, makes connector in humidity, still can work normally under the condition of drenching with rain.

Fig. 1 is the half sectional view that the utility model plug is connected with socket;

Fig. 2 is the utility model straight end-face key bit architecture schematic diagram;

Fig. 3 is the schematic diagram of the recessed housing end face of the utility model contact pin;

Embodiment: the contact idol 9 of socket 1 adopts the one sheet hyperboloid wire spring socket, the outer rim of socket 1 has three bails 4, corresponding with it is three curves on plug body 2 coupling nuts 3 inwalls, when plug 2 docks with socket 1, three bails snap in three curves, it is connected fast, be equipped with a plurality of contact idols 9 in the socket 1, each contact idol is 2.4～2.6mm with the spacing that contacts between the idol, being plane rectangular coordinates arranges, by the connector of different profile diameter, the quantity of contact idol does not wait from 7～129; Equally, also be equipped with a plurality of contacts idol 11 in the plug body 2, each contact idol also is 2.4～2.6mm with the spacing that contact between the idol, is plane rectangular coordinates and arranges, and contacts even quantity by the connector of different profile diameter and does not wait from 7～129; The contact idol 9 of socket 1 is concordant with the end face of

socket

1,10 recessed inner core 12 end faces 6～9mm of contact idol of plug body 2, and this just makes contact pin can be run at no time, has both prevented the damage of contact pin, has avoided the generation of accident again.End face at plug (seat) also is provided with five keys (groove): a major key (groove) 7, four auxilliary keys (groove) 8,9,10,11, major key (groove) 7 and auxilliary key (groove) 8,9,10, angle between 11 can have five kinds of key parallactic angle degree to arrange, by 90 °～270 ° variations, to prevent mispluging between the identical electric connector of profile, extruding cushion rubber 10 on the socket 1 and the interface sealing body 5 on the plug 1, when plug 2 is connected with socket 1, jointing end face extruding cushion rubber 10 and interface are sealed tight body 5 up for safekeeping to realize the sealing of connector, the afterbody of socket 1 and plug 2 is equipped with seals line body 6 up for safekeeping contact pin 11, jack 9 and the corresponding tight pressing of housing are realized the sealing of connector afterbody.
