At the same time, it also causes the moving contact and the conductive sheet to sinter and stick together, thereby reducing the service life of the self-locking switch. Summary of the Invention

[0004] The purpose of the present utility model is to provide a new self-locking switch to solve the problem mentioned in the background art that the movable contact and the conductive sheet are in direct surface contact during use of the existing self-locking switch, which leads to high temperature between the movable contact and the conductive sheet after long-term use, and also causes the movable contact and the conductive sheet to sinter and stick together and become inseparable, thereby reducing the service life of the self-locking switch.

[0006] Preferably, support blocks are symmetrically and fixedly connected to the top surface of the base, and the top surface of the support blocks is fixedly connected to the bottom surface of the conductive sheet.

[0007] Preferably, a static contact is fixedly connected to the center of the bottom surface of the conductive sheet, downwardly bent connecting sheets are fixedly connected to both sides of the conductive sheet, and a transverse sheet is fixedly connected to the outer wall of the connecting sheet.

[0008] Preferably, a welding hole is provided in the middle of the surface of the transverse piece.

[0009] Preferably, a moving contact is fixedly connected to the top surface of the conductive member at a position opposite to the static contact, and the moving contact is movably connected to the static contact.

[0011] Preferably, a rivet is further provided on the cover, and after the rivet passes through the base, the base is riveted to the cover.

[0012] Beneficial effects

[0013] Compared with the existing technology, the beneficial effects of the present invention are:

[0014] Combined with the above structural scheme, a static contact is installed at the bottom of the conductive sheet and a moving contact is installed on the surface of the conductive part.

[0021] like Figure 1-2 It is a structural schematic diagram of a new self-locking switch in a preferred embodiment of the present utility model. In this embodiment, a new self-locking switch includes a base 1, a cover 2 and a button 31. An installation cavity 11 is opened in the base 1, and a contact assembly 3 is installed in the installation cavity 11. A conductive sheet 4 is arranged between the base 1 and the cover 2. The contact assembly 3 is movably connected to the conductive sheet 4. The contact assembly 3 includes a button 31, a conductive member 33 and a connecting column 32. The bottom of the connecting column 32 is fixedly connected to the conductive member 33, and the top of the connecting column 32 is movably connected to the button 31. The top surface of the conductive member 33 is movably connected to the bottom surface of the conductive sheet 4.

[0022] In this embodiment, the support blocks 12 are symmetrically fixedly connected to the top surface of the base 1 around the periphery, and the top surface of the support block 12 is fixedly connected to the bottom surface of the conductive sheet 4. This structural design increases the distance between the moving contact 34 and the static contact 44, thereby reducing the arcing phenomenon between the moving contact 34 and the static contact 44 when power is on.

[0023] In this embodiment, a static contact 44 is fixedly connected to the center of the bottom surface of the conductive sheet 4 , downwardly bent connecting sheets 41 are fixedly connected to both sides of the conductive sheet 4 , and a transverse sheet 42 is fixedly connected to the outer wall of the connecting sheet 41 .

[0024] In this embodiment, a welding hole 43 is opened in the middle of the surface of the horizontal piece 42, so that the horizontal piece 42 is in surface contact with the circuit board to be installed. By opening the welding hole 43, the occurrence of cold solder joints is reduced during the soldering process between the horizontal piece 42 and the circuit board to be installed.

[0025] In this embodiment, the top surface of the conductive member 33 is located at a position relative to the static contact 44 and is fixedly connected to the moving contact 34, and the moving contact 34 and the static contact 44 are movably connected. Combined with this structural design, the static contact 44 is installed at the bottom of the conductive sheet 4 and the moving contact 34 is installed on the surface of the conductive member 3. Point contact is adopted between the moving contact 34 and the static contact 33, replacing the traditional surface contact method, thereby increasing the service life of the self-locking switch.

[0026] In this embodiment, a spring 5 is further provided between the conductive member 33 and the installation cavity 11 , and the spring 5 is used to cause the conductive member 33 to return to its original position.

[0027] In this embodiment, a rivet 6 is further provided on the cover body 2, and after the rivet 6 passes through the base 1, the base 1 is riveted to the cover body 2; this structural design, specifically when the conductive sheet 4 and the base 1 are integrally die-cast, the position of the conductive sheet 4 is relatively stable, and the base 1 and the cover body 2 can be directly connected by a robot, and then the end of the rivet 6 can be heated and riveted.

[0028] How it works

[0029] In specific use, the self-locking switch causes the movable contact 34 provided on the conductive member 33 to contact or separate from the static contact 44 on the conductive sheet 4 by pressing the button 31. Therefore, the contact assembly 3 can be used to cause the movable contact 34 to contact the static contact 44 to complete the circuit conduction, and the movable contact 34 and the static contact 44 to separate to cut off the circuit conduction.

[0030] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
