Abstract

Disclosed in the utility model is a power interface seat that comprises a DC power converter and a switch integrated with the DC power converter. The switch includes a sliding handle, a slide knob integratedly connected with the sliding handle, a springboard abutted against relatively with the slide knob, a first rear pin in supporting point connection with the springboard, and a second rear pin carrying out switching of contact/separation states with the springboard; and the sliding handle is externally exposed out of the power interface seat. A central pin of the DC power converter is connected with the first rear pin that is used as one pole of the switch and the second rear pin is used as another pole of the switch; and the second rear pin and a side pin are respectively used as connection pins of two poles of a charging loop formed by connection of the power interface seat and butting equipment. According to the utility model, the switch device is integrated based on the structure of the traditional power interface seat to realize connection and disconnection control of the power interface seat, thereby realizing effects of secure charging and energy saving.

Description

The power interface seat

Technical field

The utility model relates to a kind of power interface seat, relates in particular to a kind of outlet seat of belt switch, belongs to technical field of electronic components.

Background technology

General power interface seat only has DC power supply conversion portion, when needs charge, insert key and be connected with the DC socket, charge and finish or when not needing to charge, slotting key pulls away the DC socket, processing ease makes and inserts key and the wearing and tearing of DC socket like this, and the contact surface abrasion bad reaction such as can cause opening circuit is after charging is finished, slotting key does not pull away the DC socket, can cause the bad results such as energy waste loss, even can cause the serious problems such as leak electricity short-circuit, major accident occurs.

Understand from structure: common DC conversion connector, its center PIN is directly connected on the charge circuit, consists of in the lump the two poles of the earth pin of charge circuit with the side pin.

Summary of the invention

The purpose of this utility model is to solve above-mentioned technical problem, proposes a kind of power interface seat.

Above-mentioned purpose of the present utility model, to be achieved by the following technical programs: a kind of power interface seat, described power interface seat has the DC power supply changeover device, described DC power supply changeover device comprises the DC socket, center P IN, shell fragment and side pin, it is characterized in that: described power interface seat is provided with the switch that integrates with the DC power supply changeover device, described switch comprises sliding handle, the slider that links to each other with the sliding handle one, springboard with the relative butt of slider, make the first continuous rear foot of fulcrum and contacting/separating second rear foot that two condition switches with springboard with springboard, wherein said sliding handle exposes to the power interface seat, the center P IN of described DC power supply changeover device links to each other with first rear foot as a utmost point of switch, another utmost point that described second rear foot is switch, and second rear foot is respectively the two poles of the earth pin that the power interface seat links to each other with the service of connection devices and consists of charge circuit with the side pin.

Further, described slider and springboard are that slidingtype joins, and are provided with the spring of opening outside springboard elasticity between slider and sliding handle.

The utility model has integrated switching device by the basis at the conventional power source interface block, has realized the break-make control of power interface seat, has reached the effect of safe charging and energy savings.

Embodiment

Following constipation closes the embodiment accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.

The structural representation of the preferred version that has when as shown in Figure 1, being the enforcement of the utility model power interface seat.From illustrating as seen: this power interface seat is the product that traditional DC power supply changeover device 1 and switch 2 integrate.Wherein, this DC power supply changeover device 1 has conventional structure DC socket 11, center P IN12, shell fragment 132 and side pin 131, and its each several part design feature and function are well known to those skilled in the art, so do not describe in detail.From feature structure of the present utility model: this integrated switch comprises sliding handle 21, the slider 22 that links to each other with sliding handle 21 one, with the springboard 23 of slider 22 relative butts, make first rear foot 24 that fulcrum links to each other and contacting/separating second rear foot 25 of two condition switching with springboard 23 with springboard 23, wherein sliding handle exposes 21 in the power interface seat, carries out the contact portion of switch motion as people.From the electrical connection angle, the center P IN12 of this DC power supply changeover device links to each other with first rear foot 24, and by the utmost point of first rear foot 24 as switch; Another utmost point that this second rear foot is switch, this second rear foot is respectively the two poles of the earth pin that the power interface seat links to each other with the service of connection devices and consists of charge circuit with the side pin simultaneously.

As prioritization scheme, this slider 22 and springboard 23 be for slidingtype joins, and slider 2 and 21 of sliding handles are provided with the spring 25 of opening outside springboard elasticity.Can give springboard 23 certain pressure when slider 22 slides on springboard 23, springboard also has reaction force to slider, can slow down reaction force by spring 25, reduces the hard grind of switch and decreases.

Realize further that from the function of the utility model power interface seat it mainly comprises two states, namely power connection and power supply disconnect.

The power connection shape, as shown in Figures 2 and 3, when the operating personnel default positions that are decided to be out of sliding handle 21 of fluctuating, just drive immediately slider 22 and drive springboards 23 and overturn take first rear foot 24 as fulcrum, and be connected with second rear foot 25.Center P IN12 just by the connection of switch, particularly by this second rear foot 25, has realized that itself and side pin 131 consist of the two poles of the earth pin of charge circuit, realize charge function thus.

Power supply disconnects shape, as shown in Figure 4 and Figure 5, when the operating personnel default positions that are decided to be the pass of sliding handle 21 of fluctuating, just drive immediately slider 22 and drive springboards 23 and overturn take first rear foot 24 as fulcrum, and disconnect mutually with second rear foot 25.Center P IN12 just passes through switch thus, particularly realized the disconnection of itself and charge circuit by this second rear foot 25, at this moment, although this second rear foot 25 still is respectively the two poles of the earth pin that power interface seat 1 links to each other with the service of connection devices and consists of charge circuit with side pin 231, but because disconnecting, switch cause the relative loop of center P IN for being the shape that opens circuit, thereby realized stopping charge function without extracting in the situation of power connector.

Can find out by above-mentioned character express, after the utility model travel control switch drops into and implements, its beneficial effect is mainly reflected in: integrated switching device by the basis at the conventional power source interface block, realize the break-make control of power interface seat, reached the effect of safe charging and energy savings.

In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
