Description

The automobile trunk switch

Technical field

The utility model relates to a kind of switching device, particularly a kind of automobile trunk switch.

Background technology

In the prior art, with reference to accompanying drawing 1, the automobile trunk switch includes button parts 1, lid 2, contact spring 3, slide block 4 and jack assemblies 5, slide block is fixedlyed connected with button parts, and contact spring is fixedly connected on the slide block, and a spring is installed in the inner chamber of button parts, one end of spring is connected with button parts, the other end is against on the lid, and lid is installed in the periphery of second end of button parts, and is connected with jack assemblies.Its course of work is: after pressing the button parts, spring is compressed, button parts will drive slide block and move to the jack assemblies direction, this moment, contact spring was along with slide block moves to the jack assemblies direction, and touch plug in the jack assemblies, thus connect on-off circuit, open boot, button parts is got back to original position under the effect of spring subsequently, and circuit disconnects.

The weak point of above-mentioned technology is: button parts need drive contact spring attachment plug by slide block, implementation need guarantee the normal operation of slide block and contact spring, no matter installing or more complicated all in the use, lid is independent of button parts and jack assemblies in addition, but only as the housing of button Lower Half and the Zhi Lidian of spring, effect is simple, but needs independent die sinking and installation, cause integrally-built complexity, also increased the unreliable factor of switch operation.

Invention constitutes

The purpose of this utility model is to provide automobile trunk switch a kind of simple in structure, reliable according to the deficiencies in the prior art part.

The utility model is realized by following approach:

The automobile trunk switch, comprise button parts, spring, contact spring, lid and jack assemblies, jack assemblies includes base and plug, and plug is connected inner chamber one side of base, and its structural feature is, the integrated socket that is constructed to of lid and base, contact spring is fixedly connected on the Lower Half of button parts, and the Lower Half of button parts is socketed in the inner chamber of socket, and spring is installed in the inner chamber of button parts Lower Half, one end is against on the button parts, and an end is against on the base of socket.

After pressing the button parts, spring is compressed, and button parts will drive contact spring and move to the jack assemblies direction, after contact spring touches plug in the jack assemblies, connected on-off circuit, open boot, button parts is got back to original position under the effect of spring subsequently, and circuit disconnects.The member of whole switch omits slide block and lid, has simplified structure, has also simplified working procedure, has increased reliability of operation, has also omitted the mould and the erection procedure of slide block and lid on the other hand, has reduced the member cost.

The utility model can further be specially:

Button parts is a kind of T type member, and its Lower Half is a kind of square cavity cylinder, and contact spring is embedded in a lateral surface of cylinder admittedly.

The position of plug in like this can respective socket, because the Lower Half of button parts is that sleeve is connected in the inner chamber of socket, plug be positioned at socket inside wall on, when button parts during to the motion of the depth direction of socket contact spring also close to plug direction, after the two overlaps, by pressing, guarantee the reliable contact of the two in the gap between button parts and socket.

Have a location device in the cavity cylinder, spring is connected with this positioner.

Positioner can be convenient to the installation and the use of spring.

The square cavity cylinder can be that the rectangle cylinder also can be a square column, and chamfer configuration is adopted at four angles of cylinder.

Making things convenient for button parts and socket to carry out sleeve like this is connected.

In sum, characteristics of the present utility model are, a kind of automobile trunk switch of simplified structure is provided, it has omitted slide block and the lid in the original structure, the former contact spring that is connected with slide block is fixedlyed connected with button parts, with so-called lid and the integrated structure of socket, omitted the mould and the erection procedure of slide block and lid, reduced the member cost.Simplified working programme simultaneously, directly driven contact spring motion and contact plug, utilized the position relation between button parts and the socket cleverly, ensured engaging of contact spring and plug, improved the reliability of switch work by button parts.

Description of drawings

Figure 1 shows that the structural representation of the described automobile trunk switch of the utility model background technology;

Figure 2 shows that the isolating construction schematic diagram of automobile trunk switch described in the utility model;

Figure 3 shows that the complete section structural representation after the automobile trunk switch combination described in the utility model.

Below in conjunction with embodiment the utility model is described further.

Specific embodiment

Most preferred embodiment:

With reference to accompanying drawing 2, and joint accompanying drawing 3, the automobile trunk switch, include button parts 1, spring 2, contact spring 3 and jack assemblies, jack assemblies includes socket 4 and plug 5, plug 6, socket 4 integrated structures, and including a base and a cross section is rectangular cavity, plug 5 and plug 6 are positioned at a medial surface of cavity, and are fastenedly connected with base; Button parts 1 is a kind of T type member, and Lower Half is a kind of rectangular cavity cylinder, has a nested hole 7 on the lateral surface of cylinder, and an end fixed cover of contact spring 3 is embedded in this nested hole 7, thereby fixedlys connected with button parts 1; One location device 8 is arranged on the shaft position in the cylinder intracavity of button parts 1, and spring 2 is connected with this positioner 8, and button parts 1 sleeve is connected with socket 4 in the inner chamber of socket 4.

Therefore accompanying drawing 3 does not provide the particular location schematic diagram of contact spring, but can find out in accompanying drawing 2 owing to be full sectional view.

Its course of work is as follows:

Button parts 1 is pressed into toward the depth direction of socket 4, spring 2 is compressed, contact spring 3 is along with the plug direction of motion on base of button parts 1 is close, up to overlapping and touching, the circuit of switch is switched on afterwards, circuit controling switch is opened, and button parts 1 is replied original position under the stress effect of spring 3 subsequently, and contact spring 3 separates with plug 5, plug 6.

It is same as the prior art that the utility model is not stated part.
