Description

Technical Field

[0001] This utility model relates to the field of relay technology, and in particular to a signal relay with adjustable multi-contact spacing. Background Technology

[0002] Relays are a common control device in our lives. In layman's terms, they are switches that turn on or off when certain conditions are met.

[0003] In existing signal relay applications, the distance between its normally open and normally closed contacts is usually fixed. This presents numerous limitations when facing different circuit designs, complex operating environments, and diverse signal transmission requirements. For example, when it is necessary to adapt to different circuit board layouts, meet specific signal interference suppression requirements, or cope with changing load conditions, the fixed contact spacing is difficult to adjust accordingly, often requiring the replacement of relays of different specifications. This not only increases costs and design complexity but may also affect the overall system's operating efficiency and stability. Therefore, developing a signal relay that can conveniently and accurately adjust the distance between normally open and normally closed contacts is of significant practical importance.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a technical solution: a signal relay with adjustable multi-contact spacing, including a relay body 1. The relay body 1 includes a main body 101 and a base 102. The surface of the base 102 is provided with normally closed contacts 2. A slot 7 is opened on the surface of the base 102. A normally open contact 4 is provided above the bottom of the slot 7. A fixed base 3 is fixedly connected to the bottom of the normally open contact 4. A drive mechanism 12 is fixedly connected to the bottom of the fixed base 3. The drive mechanism 12 includes a drive block 121, a one-way lead screw 122, and a knob 123. The one-way lead screw 121... 2. A transverse rotatable connection is made to the inside of the slot 7, and the drive block 121 is threadedly connected to the surface of the one-way lead screw 122. The knob 123 is fixedly connected to one end of the one-way lead screw 122. Anti-slip ribs 13 are fixedly connected to the surface of the knob 123. The anti-slip ribs 13 are evenly distributed on the surface of the knob 123. A limit groove 8 is opened on the bottom surface of the slot 7. A limit block 9 is fixedly connected to the bottom of the drive block 121. The limit block 9 is slidably connected inside the limit groove 8. An installation hole 10 is opened on the surface of the base 102. A screw 11 is inserted into the installation hole 10.

[0022] In this embodiment, the drive mechanism 12 can easily adapt to the spatial layout requirements of different circuit boards. Whether it is a compact small circuit board or a relatively spacious large circuit board, the contact spacing can be adjusted according to the actual situation to facilitate circuit connection. This reduces the trouble of replacing the relay due to mismatched contact spacing and improves the applicability of the relay in various circuit designs. The protective rib on the knob 123 can prevent slippage when rotating the knob 123. The relay body 1 is fixed on the circuit board by inserting the screw 11 into the mounting hole 10.

[0023] Example 2: As Figure 1 - Figure 3 As shown, the surface of the base 102 is provided with scale lines 6, and the surface of the fixed seat 3 is fixedly connected with a guide rod 5, which is parallel to the scale lines 6.

[0024] In this embodiment, by using the scale line 6 in conjunction with the pointer rod 5, the distance between the normally open contact 4 and the normally closed contact 2 can be precisely controlled when adjusting the distance between them, making it convenient for operators to precisely adjust the distance between the contacts according to their needs.

[0025] The working principle of this embodiment is as follows: In use, firstly, the screw 11 is inserted into the mounting hole 10 on the base 102 of the relay body 1. Then, the base 102 of the relay body 1 is installed in the designated position on the circuit board. Subsequently, by rotating the knob 123 of the adjustment mechanism, the knob 123 drives the one-way lead screw 122 to rotate. Simultaneously, the rotation of the one-way lead screw 122 drives the drive block 121 and the fixed seat 3 at the bottom of the normally open contact 4 to move. This allows for easy adaptation to the spatial layout requirements of different circuit boards. Whether it is a compact small circuit board or a relatively spacious large circuit board, the contact spacing can be adjusted according to the actual situation, facilitating circuit connection and reducing the trouble of replacing the relay due to mismatched contact spacing. This improves the effectiveness of the relay in various circuit designs. In terms of applicability, when rotating the knob 123, the anti-slip ribs 13 on the knob 123 make full contact with the fingers, which can prevent slippage when rotating the knob 123, so as not to affect the rotation effect of the knob 123. During the movement of the drive block 121, the limiting block 9 at the bottom of the drive block 121 is always locked in the limiting groove 8 on the bottom surface of the slot 7, which prevents the multiple normally open contacts 4 from rotating during the movement. When adjusting the distance between the multiple normally open contacts 4 and normally closed contacts 2, the scale line 6 and the pointer rod 5 can be used to precisely control the distance between the normally open contacts 4 and normally closed contacts 2, which is convenient for operators to precisely adjust the distance between the contacts according to the needs of use.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
