Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a relay protection structure. Background Technique

[0002] A solid-state relay is a new type of contactless switching device. Utilizing the switching characteristics of semiconductor devices such as switching triodes and thyristors, it can achieve contactless and sparkless connection and disconnection of circuits. Due to advantages such as small control power, high reliability, long service life, and high sensitivity, it has been widely used.

[0003] At present, most relays do not have a protection and fixation structure after the connection terminals are connected. Therefore, when the relay is impacted or collided, it is easy to cause the loosening and falling off of the connection terminals, resulting in the abnormal operation of the relay.

[0004] Therefore, it is particularly important to design a relay protection structure to change the above technical defects and improve the overall practicability. Content of the Utility Model

[0005] The purpose of the utility model is to provide a relay protection structure to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A relay protection structure includes a relay body. A folded bracket is arranged at the bottom of the relay body. A plurality of buffer rubber pads are connected between the top of the folded bracket and the bottom of the relay body. A vertical plate is fixed on the front side of the relay body. A support plate strip is arranged on the front side of the vertical plate. A lower joint seat is fixed at the top of the support plate strip. A plurality of lower joint holes with the same interval are opened inside the lower joint seat. Rotating seats are arranged at both the front and rear ends of the lower joint seat on the left side of the top of the support plate strip. An upper joint seat is rotatably connected inside the rotating seat. A plurality of upper joint holes used in cooperation with the lower joint holes are opened at the bottom of the upper joint seat. A locking screw is rotatably connected to the right end of the top of the upper joint seat.

[0008] As a preferred scheme of the utility model, mounting ears are arranged on both the left and right sides of the folded bracket, and assembly holes are symmetrically opened up and down inside the mounting ears.

[0009] As a preferred scheme of the utility model, a plurality of through holes corresponding to the positions of the lower joint holes and the upper joint holes are opened inside the vertical plate at the positions corresponding to the contact heads of the relay body.

[0010] As a preferred scheme of the utility model, anti-slip gaskets are attached inside the lower joint holes and the upper joint holes.

[0011] As a preferred embodiment of the present utility model, an internal thread hole that is threadedly engaged with the locking screw is provided at the right end inside the lower seat.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, by providing a relay protection structure, the original connection method of directly connecting the wiring terminal and the contact is changed. The wiring terminals are respectively passed through the through holes of the vertical plate and then connected to the contacts of the relay body. Then, the lower half parts of the wiring terminals are respectively fixed inside the lower seat holes of the lower seat. Immediately afterwards, under the action of the rotating seat, the originally opened upper seat is closed, so that the upper seat hole of the upper seat catches the upper half part of the wiring terminal. Finally, the locking screw is threadedly locked in the internal thread hole for fixation, thereby completing the fixation of the wiring terminal and avoiding the danger that the wiring terminal is prone to loosen and fall off when the relay is impacted or collided due to lack of supporting force and protective force.

[0022] For the embodiments, please refer to Figures 1-3 , this utility model provides a technical solution:

[0023] A relay protection structure includes a relay body 1. A folded bracket 2 is arranged at the bottom of the relay body. A plurality of buffer rubber pads 3 are connected between the top of the folded bracket 2 and the bottom of the relay body 1, which can improve the buffering force for the relay body 1. A vertical plate 4 is fixed to the front side of the relay body 1, and a support plate strip 5 is arranged on the front side of the vertical plate 4;

[0024] Among them, mounting ears are arranged on both the left and right sides of the folded bracket 2, and assembly holes are symmetrically arranged up and down inside the mounting ears.

[0025] In this embodiment, please refer to Figure 2 , a lower joint seat 501 is fixed to the top of the support plate strip 5. A plurality of lower joint holes 502 with the same interval are arranged inside the lower joint seat 501. Rotating seats 503 are arranged at both the front and rear ends of the left side of the top of the support plate strip 5 and located at the top of the lower joint seat 501. An upper joint seat 504 is rotatably connected inside the rotating seat 503. A plurality of upper joint holes 505 for cooperating with the lower joint holes 502 are arranged at the bottom of the upper joint seat 504. A locking screw 506 is rotatably connected to the right end of the top of the upper joint seat 504. The wiring terminals are respectively passed through the through holes of the vertical plate 4 and then connected to the contacts of the relay body 1. Then, the lower half parts of the wiring terminals are respectively fixed inside the lower joint holes 502 of the lower joint seat 501. Immediately, the originally opened upper joint seat 504 is closed under the action of the rotating seat 503, so that the upper joint holes 505 of the upper joint seat 504 clamp the upper half parts of the wiring terminals. Finally, the locking screw 506 is threadedly locked in the internal thread hole for fixation, thereby completing the fixation of the wiring terminals;

[0026] Inside the vertical plate 4 and corresponding to the contact positions of the relay body 1, a plurality of through holes corresponding to the positions of the lower mating holes 502 and the upper mating holes 505 are provided. Anti-slip gaskets are attached to the interiors of the lower mating holes 502 and the upper mating holes 505. An internal threaded hole that is threadedly engaged with the locking screw 506 is provided at the right end inside the lower base 501.

[0027] The working process of the present utility model: When in use, change the original connection method where the wiring terminal is directly connected to the contact. Pass the wiring terminals through the through holes of the vertical plate 4 respectively and then connect them to the contacts of the relay body 1. Then fix the lower half parts of the wiring terminals inside the lower mating holes 502 of the lower base 501 respectively. Immediately afterwards, under the action of the rotating seat 503, close the originally open upper base 504 so that the upper mating holes 505 of the upper base 504 clamp the upper half parts of the wiring terminals. Finally, threadedly lock the locking screw 506 into the internal threaded hole for fixation, thereby completing the fixation of the wiring terminals and avoiding the danger that the wiring terminals are prone to loosen and fall off when the relay is impacted or collided because they have no supporting force and protective force.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
