Abstract

The utility model relates to a coupler with an opening and closing mechanism, which can be widely applied to the connection of various electric appliance equipment. The coupler comprises a plug and a socket, and is characterized in that the socket comprises a socket body, a slider, a spring, a slider fixing block, a gasket and an insert; one side of the socket body is provided with a vent hole; the slider with an exhaust slot is arranged in the vent hole; and the slider is sleeved with the gasket and the spring, and the slider fixing block is arranged outside for fixation. Under the pre-pressure of the spring, the socket is sealed, thereby preventing water from being splashed into equipment because of inadvertent use, so as to achieve the waterproofing function; when the plug is inserted in, the plug pushes the slider gasket out to leave the socket body, the exhaust slot on the slider is exposed, an exhaust channel is opened so as to realize the functions of cooling, exhausting and balancing pressure.

Description

A kind of coupler with switching mechanism

Technical field:

The utility model relates to a kind of coupler that has switching mechanism, can be widely used in the connection of various electric equipments.

Background technology:

Existing coupler generally is applicable to the electric equipment of conventional quiescent operation, occurs variety of issue easily for the use under some special statuss.For example under state was jolted in motion, the electric equipment plug shook pine easily, caused plug and coupler loose contact, caused equipment to use bad or had an accident.Can generate heat by inner components and parts when for example some electric equipment is worked, need the heat radiation exhaust, need to clean after the equipment use simultaneously, can touch water.Waterproof needs sealing, but too sealing, when when gases are heated, they expand in the equipment when surpassing certain critical value, can cause the machine blast.Can efficiently radiates heat in the time of should guaranteeing equipment work like this, the equipment that guarantees again simultaneously effective waterproof when not working.

Summary of the invention:

The utility model provides a kind of and plays water-proof function and realize heat radiation exhaust, the coupler that has switching mechanism of the function of air pressure balance.

The utility model is achieved by the following technical solution: a kind of coupler with switching mechanism, comprise plug and socket, and it is characterized in that described socket comprises jack body, slide block, spring, sliding dowel block, sealing gasket, inserted sheet; One side of jack body has air vent hole, and a slide block that has air discharge duct is housed in the air vent hole, is with sealing gasket and spring on the slide block, has sliding dowel block to fix outward;

Described slide block is the inclined-plane to the one side of plug, and bevel angle is an acute angle;

Described slide block is provided with air discharge duct, and all the other have the position of corner angle to be made as circular arc; Slide block be shaped as rectangle, circle, ellipse or circular arc;

Be provided with the elastic press type snap close around the described jack body, fix with shell;

Can be provided with transducer on the described slide block.

One side of the utility model jack body has air vent hole, and a slide block that has air discharge duct is housed in the air vent hole, is with sealing gasket and spring on the slide block, has sliding dowel block to fix outward; Under the precompression of spring, socket is in sealing state, can avoid using accidentally water being splashed into device interior, plays water-proof function; When plug inserted, plug ejected the slide block sealing gasket and leaves jack body, and the air discharge duct on the slide block exposes, and exhaust channel is opened, and realized the heat radiation exhaust, the function of air pressure balance.

Utilize the sliding stroke of slide block, but sensor installation, and whether the perception plug is inserted into position or loosening, can in time report to the police when abnormal conditions take place.

Embodiment:

As Fig. 1-shown in Figure 9: 1, jack body; 2, slide block; 3, spring; 4, sliding dowel block; 5, sealing gasket; 6, air vent hole; 7, inserted sheet; 8, plug; 9, air discharge duct; 10, elastic press type snap close.

As Fig. 1, Fig. 2, originally have the coupler of switching mechanism, comprise plug and socket.Socket comprises following assembly: jack body 1; Slide block 2; Spring 3; Sliding dowel block 4; Sealing gasket 5; Three inserted sheets 7.Socket and plug fit dimension and inserted sheet relative size can be with reference to relevant criterion.Design has air discharge duct 9 and air vent hole 6, socket to adopt three elastic press type snap closes and corollary equipment to fix on the jack body 1.

As Fig. 3, when plug did not insert, spring 3 was enclosed within on the slide block 2, and the jack body 1 of after the precommpression sliding dowel block 4 being packed into during installation makes slide block compressing sealing gasket 5 realize the sealing state of sockets by precompression.

As Fig. 4, plug inserts during work, plug withstands the inclined-plane of slide block 2, be acute angle with direction of insertion, utilize inclined-plane compressing slide block 2 in air vent hole 6, outwards to slide, make sealing gasket 5 leave jack body 1, form gas channel, as Fig. 9, realize that internal gas discharges, make the inside and outside air pressure balance of realizing of socket.

Utilize the sliding stroke of slide block 2, the sensor sensing plug can be set be inserted in and whether have looseningly in the socket, when abnormal conditions take place, can in time report to the police.

The utility model designs air discharge duct on jack body, as Fig. 6, Fig. 9, so that air pressure balance.Be provided with sealing device between air vent hole on the jack body and slide block, as Fig. 3, sealing device utilizes sliding dowel block and precompressed spring (being enclosed within on the slide block), realizes the sealing state of socket by slide block compressing sealing gasket.

Slider designs in the sealing device has air discharge duct, and all the other positions by corner angle are designed to circular arc, as Fig. 8, is convenient to slide block and slides.As Fig. 3, sealing device adopts slide block structure, and when plug inserted, plug withstood the inclined-plane of slide block, be acute angle A with direction of insertion, utilize inclined-plane compressing slide block outwards to slide, make sealing gasket leave jack body, the air discharge duct heat radiation of utilization on slide block makes the inside and outside air pressure balance of realizing of socket, as Fig. 9.

As Fig. 5, the sliding dowel block of sealing device is that fastening is on jack body.The shape of air vent hole on the jack body and supporting slide block can be rectangle, circle, ellipse and circular arc etc.As Fig. 6, the utility model adopts the install and fix mode of elastic press type snap close as socket.
