Description

[Technical field]

[0001] The utility model relates to the technical field of relays, and more specifically, to a relay which is easy to install. [Background technology]

[0002] Magnetic latching relay is an electronic control device that plays the role of automatic adjustment, safety protection, circuit conversion, etc. in the circuit. It is widely used in power protection, automation, motion, remote control, measurement and communication devices. Magnetic latching relay usually includes a base, a yoke combination, a magnetic steel assembly, a moving spring assembly, a static spring assembly and a push piece. The coil is wound on the skeleton of the yoke combination. When the current direction in the coil changes, the yoke in the yoke combination will cause the magnetic steel assembly to rotate, thereby pushing the push piece, so that the moving contact and the static contact are separated or closed.

[0003] An existing electromagnetic relay with a sheet-type push card, with a publication number of CN 107305825 A, comprises a base, a magnetic circuit part, a contact part and a push card; the push card is a sheet-type structure and is arranged between the magnetic circuit part and the contact part; a rotating shaft pointing to one side of its width is arranged at one end of the length of the push card, and the peripheral dimension of the outer end of the rotating shaft is smaller than the peripheral dimension of the inner end to form a structure with a small outside and a large inside; in the base, an axial hole roughly along the horizontal direction is arranged at the installation position corresponding to the push card, and the axial hole is arranged as a structure with a large outside and a small inside; when the rotating shaft is matched with the axial hole, only the outer end and the inner end of the rotating shaft are in contact with the hole wall of the axial hole respectively, and the middle part of the rotating shaft does not contact the hole wall of the axial hole, thereby realizing the positioning of both ends of the rotating shaft. This kind of electromagnetic relay controls the closing and separation of the upper contact part by rotating the rotating shaft in cooperation with the axial hole. This kind of electromagnetic relay device is prone to failure under long-term use conditions, and is not easy to install and replace, which reduces the practicality of the relay.

[0021] Refer to Figure 1 In an embodiment of the present utility model, a relay that is easy to install includes a base 1, a micro switch 2, a magnetic circuit assembly 3, a plurality of contact assemblies 4, and a push piece 5. The magnetic circuit assembly 3 is installed on the lower side of the base 1, a plurality of contact assemblies 4 are installed on the upper side of the base 1, a push piece 5 is provided between the magnetic circuit assembly 3 and the contact assemblies 4, and a micro switch 2 is provided at the bottom of the push piece 5.

[0022] Refer to Figure 2 、 Figure 3, in the embodiment of the present utility model, a relay that is convenient to install is provided. A push piece 5 is arranged between the magnetic circuit component 3 and the contact component 4. The magnetic circuit component 3 includes a coil 31 and a magnetic steel component 32. Both ends of the coil 31 are connected to the magnetic steel component 32 through an L-shaped connection end. A push rod 321 is arranged on the right side of the magnetic steel component 32. The push rod 321 is inserted and connected to a connection groove 62 at the bottom of the push piece 6. The contact component 4 includes a moving reed lead-out piece 41, a conductive piece 42, a moving contact 43, a static contact 44, and a static reed lead-out piece 45. The moving reed lead-out piece 41 and the static reed lead-out piece 45 are arranged alternately on both sides of the base 1. The moving reed lead-out piece 41 is connected to the conductive piece 42. The conductive pieces 42 are stacked in a "several" shape in sequence. A spring piece 421 is bent downward on the side of the conductive piece 42 away from the moving reed lead-out piece 41. A moving contact 43 is arranged on the side of the conductive piece 42 away from the moving reed lead-out piece 41. The spring piece 421 is bent inward, one end is fixed by the moving contact 43, and the other end is clamped above a first convex block 51. A static contact 44 is correspondingly arranged above the moving contact 43. The static contact 44 is arranged below one side of the static reed lead-out piece 45. The moving reed lead-out piece 41 and the static reed lead-out piece 45 respectively extend out of the base 1. A micro switch 2 is arranged at the bottom of the push piece 5. The push piece 5 includes a push vertical rod 51, a connection groove 52, and several clamping parts. A connection groove is arranged on the bottom of the push vertical rod 51 close to the magnetic circuit component 3. Several clamping parts are arranged on the back side of the upper part of the push vertical rod 51. The clamping parts include a first convex block 53 and a second convex block 54. The first convex block 53 and the second convex block 54 are respectively arranged in a staggered manner on both sides. A support block 531 is arranged obliquely downward below the first convex block 53. The number of the contact components 4 is the same as the number of the clamping parts formed by the first convex block 53 and the second convex block 54.

[0023] A relay that is easy to install according to the present utility model. When in use, the coil 31 is energized. There is a magnet assembly 32 between the L-shaped connection ends extending from both ends of the coil 31. By changing the current direction of the coil 31, the magnetic poles of the L-shaped connection ends are controlled, so as to control the rotation of the magnet assembly 32. When the magnet assembly 32 is attracted by the connection ends on both sides and rotates clockwise around the axis, the push rod is driven to rotate clockwise. The rotation of the push rod causes the connection groove 52 to be driven downward, controlling the overall downward displacement of the push piece 6. The lower side of the push piece 6 contacts the stainless steel push rod under the micro switch 2, realizing the feedback of the displacement of the push piece 6. When the push piece 6 is displaced downward, the second convex block 54 on the upper side bends the conductive piece 42 downward. The moving contact 43 at one end of the conductive piece 42 is separated from the static contact 44, and the circuit of the contact assembly 4 is disconnected; when the current in the coil 31 reverses, the magnet assembly 32 is attracted by the connection ends and rotates counterclockwise around the axis, causing the push rod on the magnet assembly 32 to also rotate counterclockwise. The rotation of the push rod drives the connection groove 52 to be driven upward, controlling the overall upward displacement of the push piece 5. The conductive piece 42 under the second convex block 54 on the upper side is reset upward. The moving contact 43 at one end of the conductive piece 42 is closed with the static contact 44, and the circuit of the contact assembly 4 is closed. By setting the first convex block 53 and the second convex block 54, the positions of the conductive piece 42 and the lower elastic piece 421 are restricted, improving the overall control ability of the push piece 4. At the same time, setting the clamping part on the same side is more convenient for installation and disassembly, improving the practicability of this kind of relay.

[0024] The above embodiments are illustrative of the present utility model, not restrictive thereof. Any solution obtained by simply changing the present utility model falls within the protection scope of the present utility model.
