Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a waterproof relay. Background Art

[0002] A relay is an electrical control device. It is an electrical appliance that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity reaches the specified requirements. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit. The relay generally includes a housing, a base plate, and a relay body. The relay body includes lead pins for installation on the mounting surface.

[0003] In the prior art, most relays do not have a waterproof function. When they need to be installed outside the cab, the relay will be damaged and fail due to water ingress. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a waterproof relay to solve the above problems.

[0005] In view of this, the utility model provides a waterproof relay, including lead pins, including:

[0006] A mounting shell, the mounting shell comprising a cover body and a shell body attached to the end of the cover body, the cover body being provided with a plurality of through holes for the lead pins to pass through;

[0007] A plurality of elastic sealing blocks are respectively installed on the inner walls around the through hole, and each sealing block is provided with a through hole for the lead pin to squeeze through;

[0008] A frame-shaped plug-in block is arranged at one end of the shell body facing the cover body;

[0009] A frame-shaped sealing block is installed on a side of the cover body facing away from the shell;

[0010] Wherein, the shell is provided with a plug-in groove for plugging in a frame-shaped plug-in block at one end of the shell, and the plurality of through holes are all located in the frame-shaped sealing block.

[0011] By adopting the above technical solution, when the lead-out pin is installed on the mounting surface, the frame-shaped sealing block is attached to the mounting surface. At this time, the frame-shaped sealing block can isolate the water source, thereby protecting the connection of the lead-out pin. Through the coordinated setting of the elastic sealing block and the perforation, the lead-out pin can be resisted, thereby preventing water from entering between the shell and the cover body through the through hole, thereby preventing water from entering and damaging the whole. Through the coordination of the frame-shaped plug-in block and the plug-in groove, the shell and the cover body can be connected, and a waterproof effect can also be achieved.

[0012] Furthermore, a sealing connection structure is provided on the side walls of the shell and the cover.

[0013] Furthermore, the sealing connection structure includes:

[0014] A first connection frame is arranged on the peripheral side walls of the shell body facing one end of the cover body;

[0015] A second connecting frame is arranged on the four side walls of the shell, and a gap is formed between the first connecting frame and the second connecting frame;

[0016] Two frame-shaped sealing gaskets are respectively arranged on opposite sides of the first connecting frame and the second connecting frame, and the two frame-shaped sealing gaskets are combined with each other;

[0017] and four bolts, the fixed ends of which are respectively arranged at the four corners of the first connection frame away from the second connection frame, and the connecting ends sequentially penetrate the first connection plate, the two frame-shaped sealing pads and are connected to the second connection frame;

[0018] Wherein, the second connection frame is provided with a threaded groove for connection of the bolt connection end.

[0019] Furthermore, a mounting assembly for integrally connecting the housing to a sheet metal of an automobile is provided on the side wall of the housing.

[0020] Furthermore, the installation component includes:

[0021] Two sliding grooves are respectively arranged on two side walls of the housing, both ends of the sliding grooves are connected to the other two sides of the housing, and the width of the sliding groove opening is smaller than the width of the groove bottom;

[0022] A sliding block, one end of which slides in the sliding groove and the other end of which extends to the notch of the sliding groove;

[0023] A mounting plate, one end of which is connected to an end of the sliding block away from the sliding groove, and the other end of which extends to the top of the housing;

[0024] Wherein, a mounting hole is provided at one end of the mounting plate away from the sliding block. BRIEF DESCRIPTION OF THE DRAWINGS
