Description

Technical Field

[0001] This utility model relates to the technical field of relays, specifically to a relay plastic part in which the frame and base are integrally formed. Background Technology

[0002] A relay mainly consists of two mechanisms: a drive mechanism and a load mechanism. The drive mechanism is primarily the relay's coil magnetic circuit, composed of a plastic frame, enameled wire, and lead wires. The frame's function is to allow the enameled wire to be wound circumferentially around it in a specific number of turns, forming a hollow cylinder. The two lead wires are fixed to the frame on the left and right sides, used to bring out the beginning and end of the enameled wire, forming a circuit. This structure is called the coil, and it is an important component of the relay coil magnetic circuit, as well as the mechanism that provides the driving force to the relay. The drive mechanism and the load mechanism are assembled at both ends of a plastic base and connected by a plastic push rod.

[0003] Most relays have a separate frame and base design, which requires subsequent assembly processes such as snap-fitting, gluing, or screw fixing. This not only increases the complexity of the production process, but also makes it easy for the frame and base to deviate due to assembly errors, thereby reducing the reliability of relay operation. Summary of the Invention

[0004] The purpose of this utility model is to provide a relay plastic part in which the frame and base are integrally formed, so as to overcome the above-mentioned defects in the prior art.

The head seat is used to install an armature and a compression spring and is disposed on the top of the column. The head seat has a socket hole coaxial with the column for installing an iron core. The base has a mounting hole 1 for installing a yoke below the head seat. One end of the base has symmetrical mounting holes 2 for installing lead pins. The other end of the base has mounting holes 3 for installing a moving spring and 4 for installing a stationary spring.

[0006] Preferably, the head seat is provided with symmetrical limiting plates on both sides, and each limiting plate is provided with a limiting groove for the insertion of the folded edge on the compression spring.

[0007] Preferably, the cross-section of the mounting hole is an "L" shaped structure.

[0008] Preferably, the mounting hole three includes a main groove for a moving spring, which is provided on the base and has a moving spring through hole on one side of its bottom wall. A secondary groove for a moving spring is provided on the other side of the main groove for a moving spring, and a bottom groove for a moving spring that communicates with the moving spring through hole is provided on the bottom wall of the main groove for a moving spring.

[0009] Preferably, the mounting hole four includes a main groove for a stationary spring and a through hole for a stationary spring. The main groove for a stationary spring is disposed on the base, and a through hole for a stationary spring is provided at one end of the bottom wall of the main groove for a stationary spring.

[0010] Preferably, the base has symmetrical weight-reducing holes on both sides of the column.

[0011] Preferably, the base has symmetrical protrusions on both sides.
