Description

Technical Field

[0001] This utility model relates to the field of relays, and in particular to a relay protection structure. Background Technology

[0002] Solid-state relays are a new type of contactless switching device. By utilizing the switching characteristics of semiconductor devices such as switching transistors and thyristors, they can achieve contactless and sparkless connection and disconnection of circuits. Due to their advantages such as low control power, high reliability, long lifespan, and high sensitivity, they have been widely used.

[0003] The relay uses a standard DIN rail mounting method, meaning the lower end of the relay has a groove that mates with a pre-installed, compatible DIN rail on the electrical box. However, due to the numerous input and output terminals of the relay, the corresponding wiring harness is also extensive, making wiring complex. Existing relays typically employ a wire clamping mechanism to prevent damage from pulling on the wiring harness. This mechanism guides the connected wiring harness through the clamping mechanism, preventing it from being pulled off and protecting the relay. However, the relay is not manufactured with a mounting position for the wire clamping mechanism, meaning it can only be installed on the electrical box. This limits the applicability of the wire clamping mechanism and presents certain drawbacks. Therefore, a relay protection structure is urgently needed to solve these problems. Utility Model Content

The first crimping seat 30 and the second crimping seat 40 are connected to the adapter base 20 through a detachable structure 60.

[0027] The input cable 71 passes through the first fastening groove 81 formed by the first crimping groove 51 and the third crimping groove 53 and is connected to the input terminal 11. The output cable 72 passes through the second fastening groove 82 formed by the second crimping groove 52 and the fourth crimping groove 54 and is connected to the output terminal 12.

[0028] In this invention, during use, the slide rail 21 on the adapter base 20 is aligned with the side end of the first slide groove 13 on the relay body 10 and pushed in, connecting the relay body 10 to the adapter base 20. Then, the second slide groove 22 on the adapter base 20 is aligned with the side end of the slide rail inside the electrical box and pushed in, connecting the adapter base 20 (relay body 10) to the electrical box. Next, the input cable 71 is connected to the input terminal 11, and the output cable 72 is connected to the output terminal 12. Then, the input cable 71 is placed into the first crimping groove 51, and the output cable 72 is placed into the second crimping groove 52. Finally, the first crimping seat 30 is installed.
