Description

Technical Field

[0001] The utility model relates to the technical field of solid-state relays, in particular to a solid-state relay with a protective flip cover. Background Art

[0002] A relay is an electrical control device. When the change of the input quantity reaches the specified requirement, it causes the controlled quantity to undergo a predetermined step change in the electrical output circuit. It plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit. It is one of the commonly used protection components in the circuit. In order to protect the wiring, a cover can be set to cover the exposed part of the wiring, thus a solid-state relay with a protective cover will appear.

[0003] A solid-state relay with a protective flap is disclosed in publication number CN202373521U, which includes a solid-state relay body and a flap arranged at the input and output terminals of the solid-state relay. The flap is rotatable and made of a translucent or transparent insulating material. The rotation angle A of the flap is from a horizontal position of degrees to a depressed position of degrees. When wiring, it is only necessary to gently lift the flap from the center of its edge to a position greater than degrees. After the wiring is completed, it is pushed back to its original position to cover all the exposed parts at the wiring, thereby achieving safety protection when the product is working normally.

[0004] However, the above scheme still has the following problems during use: when in use, the flip cover only covers the outside of the wiring point, but is not sealed, so that external moisture can still enter the interior of the relay through the gap in the flip cover, which may cause short circuit and leakage. In addition, when connecting the wires and the relay, the connection stability is relatively reduced.

[0005] Therefore, we propose a solid-state relay with a protective cover to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a solid-state relay with a protective flap, so as to solve the problem that the solid-state relay with a protective flap currently on the market mentioned in the above background technology only covers the outer side of the wiring part when in use, but does not have sealing performance, so that external water vapor can still enter the interior of the relay through the gap of the flap, which may cause short circuit and leakage caused by water ingress, and the connection between the wire and the relay is relatively simple and reduces the stability of the wiring.

[0007] To achieve the above object, the utility model provides the following technical solution: a solid-state relay with a protective flip cover, comprising a relay body, and wiring ports are evenly spaced at the top of the front and rear sides of the relay body, and the outside of the wiring ports is covered with a flip cover body, and the flip cover body is symmetrically hinged to the top of the relay body;

[0008] The invention also includes: protrusions are symmetrically fixed on the bottom of the left and right sides of the flip cover body, and the protrusions are in compression contact with the air storage bag, and the air storage bag is symmetrically installed on the top inner side of the relay body, and the outlet of the air storage bag is connected to the sealing bag, and the sealing bag is installed in the gap between the flip cover body and the relay body;

[0009] An anti-dropout clip is slidably connected through the outer inner wall of the wiring port, and the outer end of the anti-dropout clip is in contact with the outer side of the connecting line.

[0010] Preferably, the flip cover body is set to transparent plastic, and a first magnetic block is symmetrically installed on the front side of the flip cover body, and the first magnetic block is in adsorption contact with the second magnetic block, and the second magnetic block is symmetrically installed on the front and back sides of the relay body, and the magnetic poles of the first magnetic block and the second magnetic block are opposite.

[0011] Preferably, the protrusion at the bottom of the flip body is set as a rectangular structure, and after the flip body is closed, the protrusion is pressed into the top of the relay body, and the air storage bag is set as a strip structure, and the sealing bag connected to the air storage bag is set as a rectangular ring structure.

[0012] Preferably, knobs are rotatably connected to the front side of the relay body at equal intervals, and two pull ropes are wound around each knob, and the ends of the pull ropes are connected to the anti-dropout clamps, and a spring is installed between the anti-dropout clamps and the inner wall of the wiring port.

[0013] Preferably, the anti-dropout clip is configured as a "Y"-shaped structure as a whole, and the end of the anti-dropout clip is configured as an arc-shaped structure, and the anti-dropout clip forms a telescopic sliding structure through a pull rope and a spring.

[0014] Preferably, a heat dissipation groove is provided in the middle of the bottom surface of the relay body, and the heat dissipation groove runs through the left and right sides of the bottom surface of the relay body, and heat conduction plates are installed in the heat dissipation groove at equal intervals.

[0015] Preferably, a through hole is provided in the middle of the heat conducting plate, and heat dissipation holes are provided at equal intervals on the outer side of the heat conducting plate, and the heat dissipation holes and the through hole are interconnected.

[0016] Compared with the prior art, the solid-state relay with a protective flip cover of the utility model has the following beneficial effects: when in use, the gap between the flip cover and the relay can be sealed to prevent the entry of external water vapor, which may easily cause short circuit and leakage, and at the same time, the connecting wire can be reinforced to prevent it from falling off, thereby further improving the safety of the relay when in use. The specific contents are as follows:

[0017] 1. By setting the bump and the sealing bag, the gap between the flip cover and the relay can be sealed when the flip cover is closed to prevent water vapor from entering and causing short circuit and leakage;

[0018] Furthermore, when the protrusion is squeezed and contacted with the air storage bag, the gas in the air storage bag is transported to the sealing bag, and the sealing bag expands, thereby sealing the gap between the flip cover and the relay;

[0019] 2. By setting the anti-dropping clip and the spring, the connecting wire can be reinforced for a second time after being fixed to the wiring port, so as to prevent the connecting wire from being loosened from the wiring port, thereby affecting the safety of use;

[0020] Furthermore, when the knob is turned, the anti-dropout clip compression spring is driven to slide through the pull rope, so that the anti-dropout clip is separated from the connecting line for maintenance. After the knob is loosened, the anti-dropout rod will contact the outer side of the connecting line again, thereby improving the firmness of the connection.

[0021] 3. Through the setting of heat conduction plates and heat dissipation holes, the heat can be timely and effectively conducted out. The through holes and heat dissipation holes can increase the gas circulation space, so that the absorbed heat can be brought out when the gas circulates, so that the heat can be dissipated in time to avoid heat loss.

When in use, after the connecting line is connected to the wiring port 2 on the relay body 1, the flip body 3 is closed, and the first magnetic block 4 on the front side of the flip body 3 will be adsorbed with the second magnetic block 5 on the front side of the relay body 1, thereby reinforcing the closed state of the flip body 3;

[0033] Please refer to Figure 1-Figure 4As shown, convex blocks 6 are symmetrically fixed to the bottom of the left and right sides of the flip body 3, and the convex blocks 6 are in compression contact with the air storage bag 7, and the air storage bag 7 is symmetrically installed on the top inner side of the relay body 1, and the outlet of the air storage bag 7 is connected with the sealing bag 8, and the sealing bag 8 is installed in the gap between the flip body 3 and the relay body 1.

When the flip body 3 is closed, the convex block 6 will be pressed into the top of the relay body 1, and then the air storage bag 7 will be squeezed.
