Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to an electronic control relay protection structure. Background Art

[0002] A relay is an electrical device 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 requirement. It uses a small current to control a large current, acting as an automatic switch. A relay usually contains an induction mechanism, an actuator and an intermediate mechanism. The induction mechanism reflects the input variable, the actuator realizes the on or off control of the circuit, and the intermediate mechanism performs coupling isolation of the input quantity, functional processing and driving of the output part.

[0003] Existing relay protection mostly involves installing a protective shell on the outside of the relay, which is fixed by bolts. When the relay needs to be maintained or replaced, the operator needs to use specific tools to disassemble and assemble it, which reduces the efficiency of disassembly and assembly. In addition, the existing relay protective shells are mostly closed, which is not conducive to the heat dissipation of the relay during operation. Therefore, an electronic control relay protection structure is needed to meet people's needs. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-4The utility model provides a technical solution: an electronic control relay protection structure, comprising a protective shell body 1; a top plate 6 is installed at one end, and a fixing mechanism 2 is provided in the protective shell body 1; the fixing mechanism 2 comprises a symmetrical clamping plate 21 installed in the protective shell body 1, a pull ring 22 is installed at one end of the clamping plate 21, a plurality of springs 23 are installed on the side of the clamping plate 21, a plurality of semicircular grooves 24 are opened in the protective shell body 1, a slide groove 25 is opened at one end of the protective shell body 1, a slider 26 adapted to the slide groove 25 is installed at the bottom of the clamping plate 21, and a wiring groove 2 is opened on the side of the protective shell body 1 7, a connecting column 28 is installed on the side of the clamping plate 21, one end of the connecting column 28 is connected to the pull ring 22, a symmetrical card interface 7 is provided in the protective shell body 1, one end of the top plate 6 is provided with a card block 8 adapted to the card interface 7, one end of the top plate 6 is provided with a symmetrical fixing block 9, one end of the clamping plate 21 is provided with a through hole 10, one end of the fixing block 9 is provided with a support column 11, a round hole is provided on the side of the pull ring 22, the connecting column 28 is slidably installed on the side of the protective shell body 1, a plurality of round beads adapted to the semicircular groove 24 are installed at the bottom of the clamping plate 21, and one end of the spring 23 is installed at the protective shell body 1 On the inner wall, the clamping plate 21 is slidably installed in the protective shell body 1, and the column 11 is slidably installed in the through-hole 10. When the relay needs to be installed, the connecting column 28 is driven to slide by pulling the pull ring 22, and then the clamping plate 21 is driven to slide in the protective shell body 1. The spring 23 is compressed and the relay is placed between the two clamping plates 21. After the pull ring 22 is released, the spring 23 rebounds and the two clamping plates 21 are mobilized to clamp and fix the two ends of the relay. The wiring terminal of the relay is installed in the wiring groove 27 and the wiring is connected through the wiring groove 27. Then the top plate 6 is installed on the protective shell body 1, and the column 11 on the top plate 6 is used. It is installed corresponding to the through-hole 10 on the clamping plate 21 to seal the top of the relay and thus protect the relay. When it is shaken externally, the elastic force of the spring 23 reduces vibration and keeps the relay in normal operation. When the relay needs to be maintained or replaced, the pull ring 22 is pulled to make the support column 11 slide in the through-hole 10, cancel the limit on the top plate 6, remove the card block 8 through the position of the card interface 7, and then remove the top plate 6. Pull the clamping plate 21 to cancel the clamping of the relay. At this time, the relay can be taken out for maintenance and replacement without using any tools, thereby improving the disassembly and assembly efficiency of the operator.

[0023] The working principle is as follows: when the relay needs to be installed, the connecting column 28 is driven to slide by pulling the pull ring 22, and then the clamping plate 21 is driven to slide in the protective shell body 1. The spring 23 is compressed and the relay is placed between the two clamping plates 21. After the pull ring 22 is released, the spring 23 rebounds and the two clamping plates 21 are mobilized to clamp and fix the two ends of the relay. The wiring terminal of the relay is installed in the wiring groove 27 and the wiring is connected through the wiring groove 27. Then the top plate 6 is installed on the protective shell body 1, and the top of the relay is closed by correspondingly installing the support column 11 on the top plate 6 with the through-hole 10 on the clamping plate 21, thereby securing the relay. For protection, when it is shaken externally, the elastic force of the spring 23 reduces vibration and keeps the relay in normal operation. When the relay is hot during operation, heat is dissipated through the heat dissipation holes 4 on the heat dissipation plate 3, and the heat dissipation fan 5 disperses the heat. When the relay needs to be maintained or replaced, the pull ring 22 is pulled to make the support column 11 slide in the through hole 10, and the limit on the top plate 6 is cancelled. The card block 8 is taken out through the position of the card interface 7, and then the top plate 6 is taken out. The clamping plate 21 is pulled to cancel the clamping of the relay. At this time, the relay can be taken out for maintenance and replacement without using any tools, thereby improving the disassembly and assembly efficiency of the operator.

[0024] Example 2: Figure 2 As shown, a heat sink 3 is installed at one end of the protective shell body 1, and a plurality of heat dissipation holes 4 are opened on the heat sink 3. A heat dissipation fan 5 is installed in the middle of the heat sink 3. When the relay is running and generates heat, the heat is dissipated through the heat dissipation holes 4 on the heat sink 3, and the heat dissipation fan 5 disperses the heat. The remaining features are the same as those in Example 1.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
