Description

Technical Field

[0001] The utility model relates to the technical field of relays, and more specifically, to a novel relay.

Background Art

[0002] In recent years, with the rapid development of the electronic information industry, relays, as basic components, have been widely used in automation control fields such as home appliances, communications, automobiles, instrumentation, machinery, and aerospace. The latest statistical data shows that in terms of annual sales, relays have become the largest product among electronic component products. The magnetic latching relay is a novel relay developed in recent years. As one of the important components for intelligent control, it plays an important role. Like other electromagnetic relays, it automatically connects and disconnects the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay completely depends on the action of the permanent magnet, and the conversion of its switch state is triggered by a pulse electrical signal with a certain width. It has the advantages of power saving, stable performance, small size, and large load capacity, and has superior performance compared to other relays. Therefore, the magnetic latching relay is increasingly widely used.

[0003] An existing magnetic latching relay that is convenient for maintenance, with the publication number CN 115440539 A, includes a housing. An insertion interface is provided on one side of the housing, and a mounting seat is detachably arranged inside the housing. The mounting seat is inserted into the housing through the insertion interface; an armature assembly, a coil for controlling the swing of the armature assembly, and a moving contact piece and a static contact piece arranged oppositely are provided on the mounting seat; a connecting piece is arranged between the armature assembly and the moving contact piece, and the armature assembly is connected to the moving contact piece through the connecting piece, and the armature assembly is used to drive the moving contact piece to swing. This kind of magnetic latching relay does not have a feedback device and cannot judge the internal contact state, which is not conducive to actual production and use. For existing relays that use a driving part for feedback, due to space limitations, the conduction piece is small and thin, easy to break, and the force arm is small, which is not conducive to actual production and use.

Content of the Utility Model

[0004] In order to overcome the above defects of the prior art, the purpose of the present utility model is to provide a novel relay. By setting an L-shaped guide piece extending to the side, the size of the guide piece is increased, preventing it from breaking and improving the safety of the relay.

[0005] To achieve the above object, the present utility model provides the following technical solution: a novel relay, comprising a base, a coil holder, a yoke, a magnet assembly, a driving part, a moving contact seat, a static contact seat, a conductive sheet, a moving contact, a static contact, and a conduction rod. A coil holder is provided on one side of the base. L-shaped yokes are provided at both ends of the coil holder. A magnet assembly is provided between the yokes. One end of the magnet assembly is respectively connected to the driving part and the conduction rod. The conduction rod is clamped to the conductive sheet. The conductive sheet is fixed on the moving contact seat. A moving contact is provided on the conductive sheet. A static contact is correspondingly arranged on one side of the moving contact. The static contact is provided on the static contact seat.

[0006] Preferably, a coil is provided outside the coil holder, and an iron core is provided inside the coil holder.

[0007] Preferably, the magnet assembly includes a rotating body, an armature plate, a connecting groove, and a connecting rod. Armature plates are provided on both sides of the rotating body. A connecting groove and a connecting rod are provided on one side of the rotating body close to the transmission rod. The driving part is connected in the connecting groove, and the connecting rod is inserted into the conduction rod.

[0008] Preferably, the driving part includes a moving guide sheet, a static guide sheet, and a conduction sheet. One end of the moving guide sheet is inserted into the connecting groove. The static guide sheet is correspondingly arranged with the moving guide sheet. The moving guide sheet and the static guide sheet are bent and extend downward along the base. The moving guide sheet and the static guide sheet are externally connected to the conduction sheet.

[0009] Preferably, a pair of contacts are correspondingly arranged on the moving guide sheet and the static guide sheet.

[0010] Preferably, one end of the conductive sheet is fixed on the moving contact seat, and the other end is clamped in the conduction rod.

[0011] Compared with the prior art, the beneficial effect of the present utility model is:

[0012] For the novel relay of the present utility model, the driving part that could only be arranged on the upper and lower sides of the contact is bent into an L shape and extended to the side, increasing the space of the driving part, thereby increasing the width of the guide sheet of the driving part, increasing the force arm of the guide sheet, and also increasing the gap between the contacts, enabling the driving part of the relay to have a better feedback effect.
