Therefore, the use of relays is extremely extensive, and there are many types of relays in their selection. For example, reed relays are used in communication, testing, and other safety systems; high-voltage relays are used in high-voltage measuring instruments, medical equipment, cable testing machines, etc.; automotive relays are used in automotive equipment with circuit boards or quick connectors, etc. Type automotive relays; or circuit board relays commonly used with circuit boards, which can be used in communications, electronic instruments, automatic control, home appliances, etc., and installed on various circuit boards.

The applicant has been engaged in research related to the relay structure, and has been in business for a long time, and has successively filed dozens of patent applications, which have been approved and announced, but the inventor of the utility model is not complacent because of this, and still further aims at the existing relay structure Carry out relevant research and research on functional improvement, in order to keep improving and launch more practical and progressive products.

For example, for the new patent of "Relay Components" issued by China Taiwan Announcement No. M410325, the patent is as stated in its abstract: the utility model is a relay component, including a wire wheel, an iron core assembled on the wire wheel, and an iron core assembled on the wire wheel. The bracket, wherein the wire wheel is provided with an accommodating hole, the iron core is set in the accommodating hole, and the peripheral side ring of the iron core is provided with several abutting parts stuck in the accommodating hole, and there is a gap in the accommodating part , the outer diameter of the pressing part of the iron core is larger than the inner diameter of the accommodating hole, and the bracket is set between the two ends of the wire wheel. In this way, the utility model can quickly assemble and fix the iron core to the wire wheel in one direction, which is beneficial to The automatic machine platform quickly performs its assembly operation, achieving the purpose of saving assembly time of the utility model.

However, although the structure of the previous patent can quickly assemble and fix the iron core on the wire wheel in one direction, which is beneficial to the rapid assembly of the automatic machine, but the combined structure of the bracket in the previous patent will hinder its assembly. Due to the directional relationship, the assembly cannot be completed at one time on the automated machine; this is because as described in the patent specification: ... and the bracket (number 3 in the figure) is an L member, and one end and two sides are respectively provided There is a hook block that reversely buckles the barb portion (marker 132 in the figure), and the top seat (marker 12 in the figure) is provided with an inner groove (marker 121 in the figure), and the other end of the bracket (marker 3 in the figure) The setting is located in the inner groove (marker 121 in the figure), and the end of the iron core (marker 3 in the figure) is exposed in the inner groove (marker 121 in the figure), and the end bracket (marker 3 in the figure) is provided with a set fixed on The through hole (number 32 in the figure) assembled at the end of the iron core (number 2 in the figure); the bottom end seat (number 13 in the figure) is provided with a through hole (number 133 in the figure) at the bottom of the side slot (number 131 in the figure). ), and the bracket (marker 3 in the figure) is provided with a foot (marker 33 in the figure) passing through the perforation (marker 133 in the figure); the end group of the bracket (marker 3 in the figure) is provided with an L-shaped Middle shrapnel (marker 41 in the figure), one end of the middle shrapnel (marker 41 in the figure) is provided with a pole plate (marker 42 in the figure), and the middle shrapnel (marker 41 in the figure) is set with the pole plate (marker 42 in the figure). ) one end is located in the side slot (131 in the figure) of the bottom end seat (13 in the figure), the pole plate (42 in the figure) is located next to the end of the iron core (2 in the figure), and in the side slot ( In the figure number 131) the inner group is provided with the conduction pin (marker 43 in the figure) that passes outwards.... Among them, because "the group is provided with the middle elastic piece of the pole plate (marker 42 in the figure) (marker number in the figure) 41) One end is located in the side groove (131 in the figure) of the bottom end seat (number 13 in the figure); therefore, in the combination of each component, the shrapnel (number 41 in the figure) must first be combined horizontally on the bottom end seat ( Number 13 in the figure) lateral groove (number 131 in the figure), and then the pin (number 33 in the figure) of the bracket (number 3 in the figure) is inserted longitudinally in the perforation (number 133 in the figure); so that the relay It is true that the bracket 3 cannot be assembled on an automated machine at one time, which causes the complexity of the assembly process and the inconvenience of manufacture, which is a shortcoming that needs to be improved for the previous patent.

In addition, FIG. 7 is a three-dimensional schematic diagram of another existing relay structure, including a base 100, which has an electromagnetic coil 101 in the center and a side slot 102 on one side of the electromagnetic coil 101.

Wherein, since the pole plate 103 is arranged at the lower end of the electromagnetic coil 101 in a transverse direction, the combination of the pins 105 must be inserted in the longitudinal direction due to the relationship of the through hole 104. The assembly direction on the automated machine is not consistent with the front and rear processes, so the assembly cannot be completed in one go, which leads to the complexity of the assembly process and the inconvenience of manufacturing.

To sum up, the current difficulties and shortcomings in the assembly technology of the relay assembly structure are as follows:

1. Because the base uses sockets to provide pins and joints, the directionality of the pins in assembly is limited, and the combination of pins due to the limited direction will be inconsistent with the assembly direction of the front and rear processes on the automated machine and cannot be coherent The assembly is completed at one time, which causes the complexity of the assembly process and the trouble and inconvenience of manufacturing.
