Description

Technical Field

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

[0002] A relay is an electronic control device, usually used in automatic control circuits. It is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays the role of automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] A relay is usually plugged into a base, and the base of the relay is electrically connected to a circuit board. However, currently most relays only act on the lead pins of the relay through a spring on the base, thereby stably connecting the relay to the base. However, this single connection point can easily cause the relay to separate from the base during transportation, resulting in poor contact or even circuit board control failure. Therefore, the applicant has made a useful design and found a solution to the above problem. The technical solution to be introduced below is produced in this context. Summary of the invention

[0004] The purpose of the utility model is to overcome the shortcomings of the above-mentioned traditional relay base design and provide a product with reliable connection and easy operation.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A reliably fixed relay base comprises a base, wherein the base is provided with a plurality of pins corresponding to the lead-out pins of the relay, a rotatable locking plate is provided at one end of the base, buckle blocks for buckling on the relay are provided on both sides of the locking plate, so as to perform primary fixing and position limiting on the relay; the locking plate is provided with a hook block for buckling on the relay, so as to perform secondary fixing and position limiting on the relay, and the locking plate is provided with a control part for controlling the movement of the locking plate.

[0007] Preferably, the base is provided with recesses on both sides, a guide plate is provided at one end of the base, connecting plates are provided on both sides of the other end, a chamfer is provided at the entrance of the connecting plate, and a shaft is provided at the lower middle of the connecting plate.

[0008] Preferably, spring sheets are provided on both sides of the pin and are retracted toward the middle of the pin.

[0009] Preferably, one end of the locking plate is pivotally arranged on the shaft, and inclined blocks are provided on both sides of the locking plate. When the locking plate is rotated, the inclined blocks enter between the connecting plates and are connected and fixed to the connecting plates by interference fit.

[0010] Preferably, extension blocks are provided on both sides of the locking plate and are located below the buckle block, and the locking plate and the extension blocks are provided with a plurality of through holes.

[0011] Preferably, the control part is located at the top of the locking plate, and a plurality of convex strips are provided on the surface of the control part.

[0012] Preferably, the bottoms of the buckle block and the hook block are chamfered at the buckling position for initially inserting the relay.

[0013] Beneficial effects:

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model forms two fixing points for the relay by means of the buckle block and the hook block. When the relay is in the process of transportation, the bumps generated limit the relay through the buckle block and the hook block. The buckle block and the hook block share the force transmitted to the relay by the bumps, thereby extending the service life of the locking plate and improving the connection stability. The locking plate is buckled or separated from the relay by the control part to complete the fixation and removal of the relay and the base, thereby overcoming the technical problems mentioned in the background technology and making the product have the advantages of reliable connection and easy operation.

A chamfer 4 is provided at the entrance of the connecting plate 13, and a shaft 14 is provided at the middle and lower part of the connecting plate 13. When the locking plate 3 leaves the relay, the user touches the bottom of the relay through the clearance groove 11, so that the relay is separated from the base 1. When installing the relay, the guide plate 12 provides a guide for the lead pin of the relay to align with the middle of the pin 2. The chamfer 4 facilitates the entry of the inclined block 34, and the shaft 14 is used in conjunction with the locking plate 3;

[0026] It is worth mentioning that springs 21 are provided on both sides of the pin 2 and are retracted toward the middle of the pin 2. The release of the springs 21 acts on the lead pins, so that the relay is initially connected.

[0027] It is worth mentioning that one end of the locking plate 3 is pivotally arranged on the shaft 14, and inclined blocks 34 are arranged on both sides of the locking plate 3. When the locking plate 3 is rotated, the inclined blocks 34 enter between the connecting plates 13 and are connected and fixed with the connecting plates 13 by interference fit.
