Abstract

The utility model provides a lock type power supply socket, which comprises an insulating base, an insulating basal seat arranged in the insulating base, and a panel, wherein, pairs of fixed contact pieces are fixed on the insulating basal seat to form a two-phase slot or a three-phase slot, and an inserting hole corresponding to the slot is arranged on the panel. The lock type power supply socket is characterized in that the outer side of the slot is additionally provided with a locking device which comprises a pair of pressing plates and a screw rod, one end of which is sheathed with a limited spring; the screw rod penetrates through the side wall of the insulating base and the pressing plate at the head end orderly and vertically; the tail end of the screw rod and the pressing plate at the tail end are in screw connection; a post rod which is arranged on the pressing plates is in top connection with the adjacent fixed contact piece. When the screw rod is operated to be screwed in, screw threads arranged on the tail end thereof drive the pressing plates to press the adjacent fixed contact pieces through the post rod. The defects that a plug loosens and slips in contact pieces of the socket, the contact position of the socket and the plug is hot because of contact failure, etc. are avoided. The lock type power supply socket is a safe lock type power supply socket which has the advantage of favorable electrical contact.

Description

The locking-type supply socket

Affiliated technical field

The utility model provides a kind of locking-type supply socket, belongs to the supply socket technical field.

Background technology

Usually in industry and domestic environments, employed supply socket is wall type substantially, binomial or three sockets and multifunctional power socket and private jack etc., the version of these sockets all is that spring copper sheet is fixed on the insulating base, self elastic force by spring copper sheet during use clamps attaching plug, because self elastic force of spring copper sheet is limited, and use after a period of time its elastic force also can reduce or aging, make plug loosening or slippage in socket contact sheet, occur, cause easily that owing to loose contact the socket and plug contact position generates heat when therefore using, will make insulator foot distortion even thawing as long-time use.

Summary of the invention

The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, i.e. safety electric again contact good locking-type supply socket.Its technical scheme is:

Comprise the insulating base and the panel that are provided with in insulator foot, the insulator foot, be fixed with paired static contact on the insulating base and constitute two-phase slot or three-phase slot, have on the panel and the corresponding jack of slot, it is characterized in that: set up locking device in the slot outside, comprise that an a pair of pressing plate and an end are set with the swing arm of limit spring, swing arm vertically passes the sidewall of insulator foot and the pressing plate of head end successively, its terminal with terminal pressing plate is threaded, and is provided with push rod and the static contact apical grafting that closes on the pressing plate.

Described locking-type supply socket, the arranged outside that swing arm is positioned at the pressing plate of head end has guide vane end stop.

Described locking-type supply socket, the pressing plate thread connection of swing arm and head end, its thread rotary orientation is opposite with the thread rotary orientation of the pressing plate of end with swing arm.

Its operation principle is: when handling the swing arm precession, the thread belt dynamic pressure plate on the swing arm is pressed to the static contact that faces mutually through push rod, and when swing arm rotated toward rightabout, push rod leaves the static contact that faces mutually made it return to reset condition.Can avoid plug in socket contact sheet, to occur loosening like this or slippage and because the drawbacks such as socket and plug contact position heating that loose contact causes, guarantee electric good contact again promptly safely.

Description of drawings

Fig. 1 is the structural representation of the utility model one embodiment;

Fig. 2 is the structural representation after another embodiment of the utility model removes panel.

Embodiment

1, insulator foot 2, insulating base 3, panel 4, static contact 5, jack 6, pressing plate 7, swing arm 8, limit spring 9, guide vane end stop 10, push rod 11, spring

Among Fig. 1: be provided with two insulating bases 2 in the insulator foot 1, the static contact 3 that is fixed with two pairs on each insulating base 2 constitutes slot, panel 3 is provided with jack 5 corresponding to the slot place, the swing arm 7 that is set with limit spring 7 vertically passes the sidewall of insulator foot 1 and paired pressing plate 6 successively, and connect with reverse thread with paired pressing plate 6, be provided with the push rod 10 and static contact 4 apical graftings that close on of pocketed springs 11 on the pressing plate 6.By handling swing arm 7 precessions, screw thread on the swing arm 7 drives paired pressing plate 6 and inwardly moves mutually, press to the static contact 4 that faces mutually through push rod 10, the drawbacks such as socket and plug contact position heating of avoiding plug loosening or slippage in socket contact sheet, to occur and cause owing to loose contact.

Fig. 2 operation principle is substantially with Fig. 1 embodiment, just the screw thread of swing arm 7 at pressing plate 6 places of head end removed, change arranged outside guide vane end stop 9 at the pressing plate 6 of head end, like this by handling swing arm 7 precessions, driving terminal pressing plate 6 inwardly moves mutually, shorten the distance between the paired pressing plate 6, press to the static contact 4 that faces mutually, the drawbacks such as socket and plug contact position heating of avoiding plug loosening or slippage in socket contact sheet, to occur and cause owing to loose contact through push rod 10.
