Abstract

The utility model relates to a power-supply connector, in particular a power-supply connector with an electric plug and extremely high reliability. The utility model comprises a pin that includes a contact pin, an insulator, a connecting nut and a shell and a socket that includes a jack, an insulator and a shell; wherein, main keys of the pin and socket are justified; the contact pin of the pin is inserted inside the jack of the socket; the connecting nut of the pin is firmly locked inside the socket; the socket has a structure in that: a crown spring is arranged inside an external sleeve and then is arranged inside a back sleeve, the crown spring is combined with a leaf spring to form a contact, the jack external sleeve is of flexible metal material and has an end provided with a cut notch, and the cut notch of the jack external sleeve divides the end in equal parts; the outer wall of the socket is provided with a bayonet lock that has a connecting nut screwed inside the pin, which is blocked and fixed inside a bayonet lock hole on the inner wall. Compared with the prior art, the pin and socket adopt a circular bayonet type connecting which realizes fast and reliable connect and disconnect; the jack contact adopts a combined structure of a crown spring and a leaf spring, which realizes reliable power and electrical signal connecting after a plurality times of electric plug.

Description

The circular power connector of specification hot-pluggable

Technical field

The utility model relates to a kind of power connector, especially a kind of hot-pluggable and the high power connector of reliability.

Background technology

Existing power connector contact jack generally is to adopt the sheet spring structure, and its shortcoming is that jack follows the string easily and lost efficacy; The employing line spring structure that also has easily blows line spring silk but its disadvantage is exactly a warm swap, thereby makes it to lose efficacy.

Summary of the invention

The purpose of this utility model just provides the circular power connector of hot-pluggable that a kind of reliability is high, be specially adapted to the power supply connection.

For the utility model that achieves the above object adopts following technical scheme: the circular power connector of hot-pluggable, comprise plug of forming by contact pin, insulator, attaching nut, housing etc. and the socket of forming by jack, insulator, housing etc., plug aligns with socket major key position, the contact pin of plug inserts the jack of socket, the attaching nut of plug lock onto socket, described jack structure is packed into for the hat spring and is reinstalled the hat spring that the back cover forms behind the overcoat and add sheet spring composite construction jack, and the jack overcoat is elastic metallic material and termination otch fluting.

Its termination of otch fluting five equilibrium of jack overcoat described in the utility model.

Socket casing outer wall described in the utility model has bayonet lock, is fixed in attaching nut's inwall pin hole of its screw-in plug.

The utility model compared with prior art because jack contact adopts the hat spring to add sheet spring composite construction, can be realized repeatedly still reliably connecting power supply, electric power signal etc. behind the warm swap.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.As shown in Figure 3, Figure 4, the circular power connector of hot-pluggable, comprise plug of forming by contact pin 1, insulator 2, attaching nut 3, housing 4 etc. and the socket of forming by jack 5, insulator 6, housing 7 etc., plug aligns with socket major key position, the contact pin 1 of plug inserts the jack 5 of socket, the attaching nut 3 of plug lock onto socket, as Fig. 5, shown in Figure 6, described jack 5 structures pack into for hat spring 11 reinstall back cover 12 behind the overcoat 10, hat spring 11 adds the compound composition jack contact of sheet spring, jack overcoat 10 be that elastic metallic material and termination otch are slotted.

The socket outer wall of the circular power connector of hot-pluggable of the present utility model has bayonet lock 8, is fixed (as shown in Figure 3 and Figure 4) in attaching nut's 3 inwall pin holes 9 of its screw-in plug.Overcoat 10 can be that crimping, welding or plate are hinged with into back cover 12 composition contacts; Plug of the present utility model, socket adopt circular bayonet coupling, and the jack contact adopts hat spring 11 to add sheet spring mouth composite construction, and this jack is made up of hat spring 11, overcoat 10, back cover 12, and back cover 12 termination patterns can be that crimping, welding or plate connect form.When contact pin inserts jack, asked by the contact of jack sheet spring oral area at first o'clock, and then contact, finally by the logical live stream of the reliable contact of hat spring signal load with the hat spring.

Hat spring 11 be with elastic metal strip on request punching press be divided into the strip that some two ends link to each other, volume circle then, and its middle part received waist, through finalizing the design outside after the reason, the structure (as Fig. 1) that formation is small at both ends and big in the middle; Sheet spring structure jack is to be processed by elastomeric material, and end cut and closing in form (as Fig. 2).

The utility model connector is when plug and socket plug together, plug, the alignment of socket major key position screw the attaching nut and push i.e. engaging in socket bayonet lock 8 screw-in plug attaching nuts' 3 pin hole 9, the engaging process is exactly that contact pin enters jack, and then the process of reliable contact.

The core technology of the utility model connector is exactly creatively to have used hat spring 11 to add the jack of sheet spring composite construction as contact, as Fig. 5.This jack is formed (see figure 6) by overcoat 10, hat spring 11, back cover 12, overcoat 10 adopts elastic metallic material, its port cuts two equal portions (or quarter) fluting, to be preced with pack into overcoat 10 and press fit into back cover 12 backs and form these jacks (back cover can be welded type, compression joint type, plate connecting type, and the back cover is a compression joint type among Fig. 6) of spring 11.

The utility model connector has following advantage:

1. plug, socket adopt circular bayonet coupling can realize fast and reliable separation and be connected;

2. jack contact adopts the hat spring to add sheet spring composite construction, can realize repeatedly warm swap After still reliably connect power supply, electric power etc.
