Description

PCB circuit board for elevator control cabinet

Technical Field

The utility model relates to an elevator production field, concretely relates to PCB circuit board for elevator control cabinet.

Background

Printed circuit boards, also known as printed circuit boards, and PCB circuit boards, are providers of electrical connections for electronic components, and have been developed for over 100 years. The design of the circuit board is mainly a layout design, and the adoption of the circuit board has the advantage of greatly reducing errors of wiring and assembly. The circuit board can be divided into a single-sided board, a double-sided board, a four-layer board, a six-layer board and other multi-layer circuit boards according to the number of the layers of the circuit board.

An elevator control cabinet is a device for controlling the operation of an elevator and is generally placed in an elevator machine room, and a control cabinet of an elevator without machine room is placed in a hoistway. There are a large number of electrical components in the elevator control cabinet, requiring a large number of connecting wires, and also requiring connection to a large number of external devices, so PCB boards are commonly used in elevator control cabinets.

The PCB circuit board that uses in the elevator control cabinet at present generally directly punches on the board, causes life not very long, and in case the unexpected PCB circuit board appears and is pressed by the object then can lead to the PCB circuit to damage and lead to the control unit influenced, threatens elevator user's life safety.

Disclosure of Invention

In order to solve the problem, the utility model provides a PCB circuit board for elevator control cabinet can effectively guarantee the stability of using when receiving external force impact, need not to punch on the PCB circuit board, has prolonged the life of PCB circuit board, guarantees elevator user's safety in utilization.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a PCB (printed circuit board) for an elevator control cabinet comprises a PCB body, wherein the PCB body is rectangular, limiting blocks are arranged at four corners of the rectangle, one side of each limiting block is fixedly provided with the PCB body, the other side of each limiting block is provided with a convex part, and the convex part is provided with a first connecting hole;

PCB circuit board body lower terminal surface be provided with the shock attenuation board, set up the second connecting hole that corresponds with first connecting hole on the shock attenuation board.

The utility model discloses the beneficial effect who brings does: this application sets up the fixed PCB circuit board of stopper through the four corners at the PCB circuit board, does not directly trompil on the PCB circuit board but trompil on the convex part of stopper, has avoided the harm of trompil to the PCB circuit board, and the terminal surface is provided with the shock attenuation board under the PCB circuit board simultaneously, realizes shock-absorbing function through the shock attenuation board when meetting special circumstances, greatly reduced because of the harm of the circuit board that external force caused.

Detailed Description

The present invention will be described in detail with reference to fig. 1 to 4.

As shown in fig. 1-4, a PCB for an elevator control cabinet comprises a PCB body 1, wherein the PCB body 1 is rectangular, four corners of the rectangle are provided with limit blocks 2, one side of each limit block 2 is fixed with the PCB body 1, the other side of each limit block is provided with a convex portion 11, and the convex portion 11 is provided with a first connecting hole 112;

the lower end face of the PCB body 1 is provided with a damping plate 3, and the damping plate 3 is provided with a second connecting hole 31 corresponding to the first connecting hole 112;

the damping plate 3 and the limiting block 2 are fixedly connected with a position needing to be fixed through a fastening screw.

Through setting up fixed PCB circuit board main part 1 of stopper in PCB circuit board main part 1's four corners, do not directly go up the trompil at PCB circuit board main part 1 but set up first connecting hole 112 on the convex part of stopper 2, the harm of trompil to PCB circuit board main part 1 has been avoided, the terminal surface is provided with shock attenuation board 3 under PCB circuit board main part 1 simultaneously, shock attenuation board 3 and stopper 2 pass first connecting hole 112 and second connecting hole 31 through fastening screw, link firmly with the position that needs to fix, realize shock-absorbing function through shock attenuation board 3 when meetting the special circumstances, greatly reduced because of the harm of the circuit board that external force caused.

Embodiment 1, the damper plate 3 include first elastomeric material layer 32 and second elastomeric material layer 33, be provided with foam aluminium layer 34 between first elastomeric material layer 32 and the second elastomeric material layer 33, first elastomeric material layer 32 and the unanimous and foam aluminium layer 34's of second elastomeric material layer 33 thickness is greater than the thickness of first material layer 32, realize shock-absorbing function through multilayer elastomeric material layer, the centre sets up foam aluminium layer 34 and has further strengthened absorbing sound, shock-absorbing function and the quality of damper plate 3 and be light.

In example 2, the spring layer 35 is provided between the first elastic material layer 32 and the second elastic material layer 33, and the spring layer 35 is uniformly arranged. Compared with the foam aluminum layer 34, the spring layer 35 has lower manufacturing cost and can achieve the equivalent shock absorption function, and is suitable for enterprises with requirements on cost.
