Description

Technical Field

[0001] This utility model relates to the field of relay technology, and specifically to a relay assembly. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in an electrical output circuit when the input quantity changes to a specified value. Relays have both a control system and a controlled system, and are commonly used in automated control circuits, playing roles such as automatic adjustment, safety protection, and circuit switching.

[0003] Existing relays are typically connected to their mounting bases using bolts. However, the vibration-damping design between the relay and the mounting base is inadequate, making the relay prone to loosening or damage when subjected to external vibrations or impacts. Furthermore, the lack of protection at the bolt connections allows dust to accumulate, making disassembly and assembly difficult. Additionally, the relays are often located close to other components, making them difficult to remove and hindering future maintenance. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a relay assembly with reasonable structural design, good vibration resistance, good dustproof effect, easy assembly and disassembly operation and good practicality.

[0006] The bottom of the mounting base is provided with an annular groove, and an elastic dustproof pad is provided inside the annular groove. The bottom of the mounting base is also provided with several elastic sheets.

[0007] The top of the relay body is integrally provided with a connecting protrusion, and a gripper is provided on the connecting protrusion. The gripper includes a connecting base plate, a support rod, and a gripper crossbar. The connecting base plate and the connecting protrusion are connected and fixed by screws. The lower end of the support rod is integrally provided with the upper end surface of the connecting base plate, and the upper end of the support rod is integrally provided with the gripper crossbar.

[0008] The present invention is further configured such that: the positioning block is provided with a plurality of stepped through holes vertically, the upper end face of the mounting base is provided with a threaded hole aligned with each stepped through hole, a fixing bolt passes through each stepped through hole, and the head of each fixing bolt passes through the stepped through hole and is threadedly connected to the aligned threaded hole.

[0009] The present invention is further configured such that: a dustproof block is provided on the positioning block, and a dustproof plug is integrally provided on the lower end face of the dustproof block, aligned with the upper port position of each stepped through hole, and the dustproof plug is inserted into the aligned stepped through hole.

[0010] The present invention is further configured such that: the positioning block is made of plastic or stainless steel, and one side of the positioning block is integrally formed with the lower end of the side wall of the relay body or is fixed by adhesive or screw connection; the dustproof block and the dustproof plug are both made of rubber or silicone.

[0011] The present invention is further configured such that: a connecting protrusion is integrally provided at the upper end of the elastic dustproof pad, and the connecting protrusion is bonded and fixed to the inner wall of the annular groove; the elastic dustproof pad is made of silicone material.

[0012] The present invention is further configured such that: the mounting base is made of insulating plastic and has a plurality of conductive sheet through holes; a plurality of conductive sheets are fixedly disposed on the bottom of the relay body, and the lower end of each conductive sheet passes through the lower port of the aligned conductive sheet through hole; the elastic sheet is made of plastic or stainless steel and is integrally disposed with the bottom of the mounting base or fixed by screws.

[0013] The beneficial effects of this utility model are: compared with the prior art, the structure of this utility model is reasonable. The elastic dustproof pad and elastic sheet at the bottom of the mounting base can deform and alleviate the vibration of the relay body, so that the relay body has good anti-vibration performance and is not easy to loosen or be damaged when subjected to external vibration or impact.

[0014] A positioning block is fixedly installed at the lower end of the side wall of the relay body. The positioning spring in the bottom spring mounting groove of the positioning block can deform and relieve vibration, making the positioning block connection reliable and not easy to loosen.
