Description

Passenger car glove compartment lamp switch

Technical Field

The utility model relates to the field of automobile switches, in particular to a glove compartment lamp switch of a passenger car.

Background

The switch of the glove box lamp of the passenger car is a normal pressure switch, namely, when the switch is not used, the button is in a pressing state for a long time, when the glove box is opened, the button is loosened, the circuit is conducted, and the glove box lamp is lighted. Because the opening frequency of the glove box is lower, the contact piece and the inserting piece in the switch are in a separated state for a long time, the positions of the contact piece and the inserting piece are exposed in the air for a long time, surface oxidation is easy to occur, and when the contact piece is contacted again, a circuit signal can not be conducted due to an oxide layer on the surface, so that the glove box lamp can not be normally lightened. Therefore, it is necessary to adjust the existing structure to overcome the problem that the surface oxidation circuit cannot be conducted without using for a long time.

Disclosure of utility model

The utility model aims to provide a contact sheet type switch for a glove box lamp switch of a passenger car, which solves the problem that the conventional switch structure is easy to be used for a long time and cannot be normally conducted.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a passenger car glove compartment lamp switch, includes the casing, fixes the base below the casing, installs the button that can reciprocate on the casing, be provided with a pair of inserted sheet in the casing, be provided with the contact patch of connecting two inserted sheets in the casing, be provided with first spring between contact patch and the base, be provided with the second spring between contact patch and the button; the contact piece comprises a flat piece and elastic arms arranged on two sides of the flat piece, and contact pins are arranged at the tail ends of the elastic arms.

Further, the contact piece is located below the contact point of the two inserting pieces, and the elastic arm is of an obliquely upward arrangement structure.

Preferably, the contact piece is made of beryllium bronze.

Preferably, the thickness of the contact piece is 0.15mm.

In order to improve the contact reliability, the tail ends of the elastic arms are provided with two contact pins in parallel.

The utility model has the beneficial effects that: according to the utility model, through the structural design of the elastic arm of the contact piece, the elastic arm is pressed and deformed in the process of contacting the contact piece with the inserting piece, so that the contact pin at the front end acts on the inserting piece with a certain pressure and slides on the inserting piece, and the oxide layers on the inserting piece and the contact pin are wiped off, thereby ensuring the conduction reliability of the switch. The contact piece is made of beryllium bronze material, and has good oxidation resistance and good elasticity. The number of the contact pins is 2, the width of a single contact pin can be reduced, the contact pins can be enabled to take out the oxide layer on the surface more easily, and as long as one of the contact pins is conducted, the switch is conducted, so that the reliability of conduction can be further improved.

Detailed Description

Examples: as shown in fig. 1 to 4, a glove compartment lamp switch for a passenger car comprises a shell 1, a base 2 fixedly arranged below the shell 1 in a clamping manner, a button 3 arranged on the shell 1 and capable of moving up and down, a pair of inserting pieces 4 arranged in the shell 1, and a contact piece 5 connected with the two inserting pieces 4 arranged in the shell 1, wherein when the contact piece 5 is in contact with the two inserting pieces 4, a circuit is conducted. A first spring 6 is arranged between the contact piece 5 and the base 2, and a second spring 7 is arranged between the contact piece 5 and the button 3. When the glove box is closed, the button 3 is pressed, the first spring 6 and the second spring 7 are compressed, the contact piece 5 moves downwards, and the contact piece is separated from the inserting piece 4, so that the circuit is disconnected. When the glove box is opened, the button 3 loses the downward pressure and is ejected upwards under the action of the first spring 6 and the second spring 7, and meanwhile, the contact piece 5 moves upwards under the action of the first spring 6, so that the contact piece 5 is in contact conduction with the contact positions of the two inserting pieces 4.

In order to improve the contact reliability and prevent the surface oxidation circuit of the contact piece 5 and the insertion piece 4 from being unable to be conducted, the contact piece 5 is made of beryllium bronze with the thickness of 0.15mm, and the beryllium bronze has the advantages of good elasticity and strong oxidation resistance. The contact piece 5 is located below the contact point of the two inserting pieces 4, and comprises a flat piece 51 and elastic arms 52 arranged on two sides of the flat piece 51, the elastic arms 52 are of an obliquely upward arrangement structure, and contact pins 53 are arranged at the tail ends of the elastic arms 52. When the contact piece 5 moves upwards, the contact pin 53 is contacted with the inserting piece 4, the contact pin moves upwards continuously, the elastic arm 52 deforms, the contact pin 53 slides on the inserting piece 4, and the oxide layer on the surface can be effectively removed under the action of friction force, so that the conduction of a circuit is ensured. In order to improve the reliability of the conduction, the two contact pins 53 are disposed at the end of the elastic arm 52 in parallel, so that as long as one of the contact pins 53 is conducted, the circuit is conducted, and the problem of unstable circuit conduction caused by poor contact of one of the contact pins 53 can be effectively prevented.

The utility model has been described above by way of example. It will be clear that the utility model is not limited to the embodiments described above. As long as various insubstantial improvements are made using the method concepts and technical solutions of the present utility model; or the utility model is not improved, and the conception and the technical scheme are directly applied to other occasions and are all within the protection scope of the utility model.
