SUMMERY OF THE UTILITY MODEL
The utility model provides an electromagnetic relay's base structure and electromagnetic relay, it has overcome prior art electromagnetic relay's coil pin leads to the poor weak point of assembly line because of warping.
The utility model provides a technical scheme that its technical problem adopted is: a base structure of an electromagnetic relay is provided with two pin holes for two coil pins of the electromagnetic relay to pass through one by one; the pin hole is in a funnel shape with a wide upper part and a narrow lower part.
Furthermore, the pin hole comprises an upper hole section and a lower hole section, the aperture of the upper hole section is gradually reduced from top to bottom, the lower hole section is a straight hole section, and the cross section size of the lower hole section is matched with the cross section size of the coil pin.
Further, the depth of the upper hole section is larger than that of the lower hole section.
Furthermore, the cross section of the pin hole is square.
Furthermore, bosses respectively extend downwards at the positions of the pin holes at the bottom end of the base, and the pin holes respectively extend downwards to the bottom ends of the corresponding bosses.
Furthermore, a dispensing slot is arranged at the bottom end of the boss and communicated with the corresponding pin holes.
The utility model also provides an electromagnetic relay, which comprises a base and a coil rack, wherein the coil rack is provided with two coil pins; the base adopts the aforesaid electromagnetic relay's base structure, two coil pins pass respectively one by one two pin holes.
Further, the length of the coil pin is 15-20 cm.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. the pin holes are funnel-shaped with wide top and narrow bottom, so that even if the coil pins are slightly deformed, the pins can be guided through the funnel-shaped holes to smoothly pass through the pin holes of the base, and the assembly performance of the coil pins is improved.
2. Because the pin hole includes upper hole section and lower hole section, the aperture from the top down of upper hole section is gradually littleer, and the lower hole section is the straight hole section for the lower hole section in pin hole can straighten the coil pin, avoids because of the coil pin interval changes greatly, leads to the relay product can't pack into the PCB board smoothly and cause and use badly.
3. The arrangement of the boss enables the depth of the pin hole to be increased, so that the coil pin can be protected, and the coil pin is enabled to be less prone to deformation under the action of external force.
The present invention will be described in further detail with reference to the accompanying drawings and examples; however, the base structure of the electromagnetic relay and the electromagnetic relay of the present invention are not limited to the embodiments.

Detailed Description
In an embodiment, please refer to fig. 1 and fig. 2, the base structure of an electromagnetic relay of the present invention is provided with two pin holes 1 for two coil pins of the electromagnetic relay to pass through one by one; the pin holes 1 are in a funnel shape with a wide upper part and a narrow lower part.
In this embodiment, the cross section of the pin hole 1 is square, the pin hole 1 includes an upper hole section 11 and a lower hole section 12, and the hole diameter of the upper hole section 11 is gradually reduced from top to bottom; the lower hole section 12 is a straight hole section, and the cross-sectional dimension of the lower hole section 12 is adapted to the cross-sectional dimension of the coil pin. The depth of the upper bore section 11 is greater than the depth of the lower bore section 12, but is not limited thereto, and in other embodiments, the depth of the upper bore section 11 is less than or equal to the depth of the lower bore section 12.
In this embodiment, the bottom end of the base has bosses 2 extending downward at positions of the pin holes 1, and the pin holes 1 extend downward to the bottom ends of the bosses 2, that is, the pin holes 1 are distributed to penetrate through the bosses 2, and a part of the pin holes 1 is formed on the bosses 2. So, make the degree of depth greatly increased in pin hole 1 to can protect the coil pin, make the coil pin stand external force effect and be more difficult to warp. The bottom end of the boss 2 is provided with a dispensing groove 21, and the dispensing groove 21 is communicated with the corresponding pin holes.
The utility model discloses an electromagnetic relay's base structure establishes its pin hole 1 into behind the infundibulate for 1 open-top end bore greatly increased in pin hole, therefore, even there is slight deformation to the coil pin, also can get into pin hole 1 through the heavy-calibre opening on 1 top in pin hole, and lead and pass pin hole 1 of base smoothly by the slope wall of the section of going up 11 of pin hole 1, thereby improve the assembly nature of coil pin.
