Description

Technical Field

[0001] This utility model relates to the field of relay technology, specifically to a relay with high load-bearing capacity. Background Technology

[0002] A relay is an automatic control device whose output changes abruptly when the input (electric, magnetic, sound, light, heat) reaches a certain value. The main component of a relay is an electromagnetic relay assembly, including a moving contact, a stationary contact, a connecting plate, an electromagnetic coil, a frame for fixing the electromagnetic coil, a fixing plate for fixing the frame, and the connecting plate. The moving and stationary contacts are usually separate. The connecting plate is located at both ends of the electromagnetic coil. When the electromagnetic coil is energized, it generates a magnetic force that attracts the moving contact, causing it to press against the stationary contact, thus achieving the abrupt change in state. There are two sets of stationary contacts, and the relay's moving contact has two moving contacts that respectively cooperate with the two sets of stationary contacts.

[0003] Existing relays typically have two moving contacts and two stationary contacts working together, which means they can only handle very small currents and cannot handle large currents, thus reducing their applicability. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide a relay with high structural strength and high load-bearing capacity.

[0005] To address the above problems, the following technical solution is provided: A relay with high load-bearing capacity includes a base, an electromechanical assembly mounted on the base, and a housing that cooperates with the base. The electromechanical assembly includes a frame, an electromagnet mounted inside the frame, a connecting plate connected to the frame, an armature connected to the connecting plate and located at one end of the electromagnet, a moving contact plate linked with the armature, and a stationary contact plate mounted on the base and disposed opposite to the moving contact plate. One end of the moving contact plate is connected to the armature, and the other end extends outward to a position opposite to the stationary contact plate. The moving contact plate is provided with a moving contact, and the stationary contact plate is provided with a stationary contact corresponding to the moving contact.

[0006] In the above structure, by setting a moving contact on the moving contact plate to cooperate with a stationary contact on the stationary contact plate to achieve opening and closing, its ability to carry high current can be improved, thereby improving the load-bearing capacity of this utility model and expanding the scope of application of this utility model.

[0007] The present invention is further configured such that one end of the movable contact plate fixed to the armature by a rivet is a fixed end, and the other end corresponding to the stationary contact plate is a connecting end, and the movable contact is located on the connecting end.

[0008] In the above structure, the fixed end facilitates the fixing of the moving contact plate, and the connecting end facilitates its cooperation with the stationary contact plate to achieve opening and closing.

[0009] The present invention is further configured such that the cross-section of the moving contact plate is T-shaped, and the length of the fixed end is greater than the width of the connecting end.

[0010] By adopting the above structure, the elastic reset capability of the moving contact plate can be improved, thereby improving the reliability of this utility model.

[0011] The present invention is further configured such that a slot is provided on the outer side of the shell opposite to the connecting end, and an arc guide block is installed in the slot.

[0012] In the above structure, the arc guide block serves to initiate an arc, thereby improving the safety of this invention. The slot facilitates the installation of the arc guide block, thus improving the ease of assembly.

[0013] The present invention is further configured such that a pin is installed on one end of the I-beam frame relative to the moving contact plate. The pin is provided in two sets, located on both sides of the electromagnet. One end of the pin is inserted into the I-beam frame to form a positioning end, and the other end passes through the base to form a wiring end.

[0014] In the above structure, mounting the pins on the I-beam frame can improve the stability and firmness of the pins, and placing the pins on both sides of the electromagnet can reduce the installation distance between the two pins, thereby improving the convenience of wiring of this utility model.

[0015] The present invention is further provided in that the base has a protrusion on the side facing the shell that abuts against the I-beam frame, and the protrusion has a connecting groove adapted to the pin.

[0016] In the above structure, the stability of the I-beam frame can be improved by setting protrusions, and the stability of the pins can be further improved by setting connecting slots, thereby improving the reliability of this utility model.

[0017] The present invention is further configured such that a protruding ridge is provided on the side of the positioning end facing the outside of the housing, and the protruding ridge is tapered towards the pin installation direction.

[0018] In the above structure, the protruding ridge can improve the connection strength between the pin and the I-beam frame, achieve the function of preventing backlash, and thus improve the stability of the pin and the reliability of this utility model.

[0019] The present invention is further configured such that a plurality of protruding ridges are provided facing the pin mounting direction.

[0020] By adopting the above structure, the connection strength between the pin and the I-beam can be further improved, thus enhancing the reliability of this utility model. Attached Figure Description

If the specific posture changes, the directional indicator will also change accordingly.

[0032] like Figures 1 to 8The relay shown includes a base 1, an electromechanical assembly 2 mounted on the base 1, and a housing 3 that cooperates with the base 1.

The moving contact plate 25 is provided with a moving contact 251, and the stationary contact plate 26 is provided with a stationary contact 261 corresponding to the moving contact 251.

[0034] In this embodiment, the end of the moving contact plate 25 that is fixed to the armature 24 by rivets is the fixed end 252, and the end corresponding to the stationary contact plate 26 is the connecting end 253. The moving contact 251 is located on the connecting end 253.

[0035] In the above structure, the fixed end 252 facilitates the fixing of the moving contact plate 25, and the connecting end 253 facilitates its cooperation with the stationary contact plate 26 to achieve opening and closing.
