Description

Technical Field

[0001] The utility model relates to the technical field of relays, and in particular to a shell which can effectively prevent a frame from being sunken due to external force. Background Art

[0002] A relay is an electronic control device, usually used in automatic control circuits, where it performs functions such as automatic adjustment, safety protection, and circuit conversion. Existing relays mainly include coils, cores, coil covers, insulating washers, wiring, and terminals. When producing and processing relays, the relays need to be tested. During the test, a shell is often used to protect the relay, which can effectively prevent the frame from being sunken due to external forces.

[0003] However, the existing processing equipment has the following shortcomings:

[0004] When the equipment is in use, when the relay is conducting a semi-finished product test, it is necessary to pre-press the product from the side. The relay and the housing are prone to not fitting properly. During the pre-pressing process, the other side may be pressed down, resulting in the phenomenon of product long and short legs, leading to product defects. The occurrence of such defects is reduced. When the equipment is in use, when the cover is connected to the housing, the cover is generally secured to one end of the housing with a buckle. The buckle connection is prone to sliding after long-term use, causing the cover to detach from the housing surface, exposing the equipment inside the housing to the air, and allowing debris to easily enter the housing, causing the equipment to be damaged and difficult to use.

[0005] Therefore, we propose a shell that can effectively prevent the frame from being dented due to external force, so as to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to solve the shortcoming of the prior art that the relay is easily damaged, and proposes a shell which can effectively prevent the frame from being concave due to external force.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a shell that can effectively prevent the skeleton from concave due to external force, including a shell and a protective device, the surface of the shell is provided with a groove, the surface of the shell is provided with an air outlet, a cover is provided at one end of the shell, one end of the shell is fixedly connected to a limiting block, a protective device is provided inside the shell, the protective device includes an increased boss and an air hole boss, the increased boss is fixedly connected to the inside of the shell, the air hole boss is located and fixedly connected to the inside of the shell, the surface of the air hole boss is provided with a connecting hole, and the connecting hole is connected to the air outlet.

[0008] Preferably, a connecting groove is provided at the bottom of the interior of the shell, and a first connecting plate is fixedly connected to one end of the interior of the shell. By arranging the first connecting plate inside the shell, the relay and the shell can be initially isolated, thereby reducing the risk of the relay being easily bumped when the equipment is in use, thereby causing direct collision damage to the relay.

[0009] Preferably, a second connecting plate is fixedly connected to the inner side surface of the shell, and a stop plate is fixedly connected to the bottom of the shell, and the stop plate is provided to facilitate preliminary buffering of the relay.

[0010] Preferably, a push rod is provided above the push plate, and the push rod is fixedly connected to the inside of the second connecting plate. The push rod is provided to facilitate limiting the relay.

[0011] Preferably, a stabilizing device is provided on the side of the shell, and the stabilizing device includes a first stabilizing plate and a second stabilizing plate, the first stabilizing plate is fixedly connected to the side of the shell, the second stabilizing plate is fixedly connected to the side of the cover, a stabilizing hole is provided inside the first stabilizing plate, a pressing hole is provided inside the second stabilizing plate, a card plate is slidably connected to the inner wall of the pressing hole, and a sliding hole is provided on the surface of the card plate. By providing the card plate, the cover and the shell can be effectively and firmly connected, thereby reducing the situation where the cover is prone to shaking and detaching from the shell surface when the device is in use, exposing the relay inside the shell.

[0012] Preferably, a sliding rod is fixedly connected to the inner wall of the pressing hole, and the sliding rod is slidably connected to the inner wall of the sliding hole. The sliding rod is provided to facilitate limiting the clamping plate.

[0013] Preferably, a spring is fixedly connected to the surface of the card plate, and one end of the spring away from the card plate is fixedly connected to the inner wall of the pressure hole. The spring is provided to facilitate applying a restoring elastic force to the card plate.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. In the utility model, when using the equipment, the user connects the relay with the housing, and then places the relay in a pressing machine for pressing test. When using the equipment, the user combines the finished relay to be tested with the inside of the housing, and then places the relay with the added boss, suspends the relay inside the housing, and protects the relay. By setting a protective device, the relay is effectively protected, and the role of protecting the relay is played. When the equipment is in use, when the relay is testing the semi-finished product, the product needs to be pre-pressed from the side. The relay and the housing are prone to not being properly matched. During the pre-pressing process, the other side may be pressed down, resulting in the phenomenon of long and short legs of the product, resulting in defective products, thereby reducing the occurrence of such undesirable phenomena.

[0016] 2. In the utility model, by providing a stabilizing device, when using the device, the user presses the card plate, and when the card plate moves, it drives the spring to displace and deform to generate elastic force, and then the card plate moves out of the inside of the stabilizing hole, and then the first connecting plate loses its restraint, and pulls the cover off the surface of the shell. By providing a stabilizing device, the cover is effectively stabilized, and the cover and the shell are firmly connected. When the device is in use, when the cover and the shell are connected, the cover is generally secured to one end of the shell by a buckle. The buckle connection is easily slipped after long-term use, causing the cover to be separated from the shell surface, exposing the internal equipment of the shell to the air, and debris to easily enter the shell, causing the equipment to be damaged and difficult to use, thereby improving the stability of the equipment.
