Detailed Description
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
As shown in fig. 1 to 5, a first embodiment of the present application provides an electronic coil including a coil body 10, a wire insertion portion 20, a circuit board 30, and a support portion 40, the wire insertion portion 20 is disposed on the coil body 10, the wire insertion portion 20 includes a coil connection portion 21 and a housing 22, a pin 23 is disposed on the coil connection portion 21, and the housing 22 is housed on the coil connection portion 21. The circuit board 30 is inserted through the pin 23, the supporting portion 40 is disposed on the coil connecting portion 21, the supporting portion 40 is at least partially attached to the circuit board 30, the supporting portion 40 is used for supporting the circuit board 30, and a supporting surface of the supporting portion 40 is abutted to the circuit board 30, so that a gap is formed between the coil connecting portion 21 and the circuit board 30.
Specifically, the circuit board 30 in this embodiment is provided with a through hole, the through hole is disposed on the pin 23, and the pin 23 and the supporting portion 40 are disposed at intervals. In this way, after the wiring board 30 is inserted through the pins 23, the wiring board 30 is moved to a position where it is attached to the supporting portion 40, so that the wiring board 30 is supported by the supporting portion 40, and the length of the supporting portion 40 is the gap between the wiring board 30 and the coil connecting portion 21. Because of the gap, in order to connect the circuit board 30 and the pin 23, the soldering operation is performed at the through hole, and the soldering operation is performed at one side of the circuit board 30, so that the soldering liquid flows from one side of the circuit board 30 to the other side, and the soldering reliability of the circuit board 30 and the pin 23 can be ensured. Therefore, the electronic coil provided by the embodiment can solve the technical problem of poor welding reliability of the circuit board 30 and the contact pin 23 of the electronic coil in the prior art.
In this embodiment, the supporting portion 40 includes a plurality of supporting columns, and the plurality of supporting columns are disposed at intervals. By adopting the structure, the stability of the support can be improved, so that a gap is formed between the circuit board 30 and the coil connecting part 21, and the welding liquid on one side of the circuit board 30 can flow into the other side of the circuit board 30 through the gap between the through hole and the contact pin 23, thereby effectively ensuring the welding firmness. Specifically, the support columns in this embodiment may be 4, and 4 support columns are located at four vertex angles of the parallelogram, and by adopting such a structural layout, the stability of the support can be improved. Specifically, the pins 23 are plural, 2 support columns are located on the upper sides of the plural pins 23, and 2 support columns are located on the lower sides of the plural pins 23.
Specifically, the cross section of the support column may be circular or rectangular, i.e. the support column may be a cylindrical structure or a polygonal column structure.
In order to provide a sufficient gap between the wiring board 30 and the coil connecting portion 21, the height of the supporting portion 40 is h,1 mm.ltoreq.h.ltoreq.4 mm in the present embodiment. Specifically, when the height of the supporting portion 40 is less than 1mm, the gap between the wiring board 30 and the coil connecting portion 21 is made too small, which makes it inconvenient for the solder liquid to flow from one side of the wiring board 30 to the other side; when the height of the supporting portion 40 is greater than 4mm, the gap between the wiring board 30 and the coil connecting portion 21 is excessively large, which is disadvantageous in terms of compactness of the whole structure.
In the present embodiment, the coil connecting portion 21 includes a housing connecting portion 211 and a wire connecting portion 212, the wire connecting portion 212 is provided protruding from the housing connecting portion 211, the housing 22 is provided on the housing connecting portion 211, and the pin 23 is provided on the wire connecting portion 212. The wire connecting portion 212 is further provided with a waterproof structure 50, the waterproof structure 50 is an annular structure, and the contact pin 23 is located in the annular structure. With such an arrangement, the annular structure is arranged around the plurality of pins 23, and a sealing material (typically, epoxy resin) is filled between the housing 22 and the coil connecting portion 21 to seal. The annular structure is mainly used for increasing the contact area between the annular structure and the sealing material so as to improve the sealing performance of the annular structure, so that the phenomenon that the sealing material and the coil connecting part 21 fall off can be better avoided, the waterproof effect is better achieved, and water is prevented from flowing into the contact pin 23. Specifically, the wire connection portion 212 has a mounting surface, and the supporting portion 40 protrudes from the mounting surface to raise the circuit board 30 through the supporting portion 40.
Specifically, the waterproof structure 50 may be a waterproof tank. With such an arrangement, when the sealing material is filled between the cover 22 and the coil connecting portion 21, the contact area between the sealing material and the annular waterproof groove can be increased compared to a planar structure, thereby improving the sealing performance.
In particular, the waterproof structure 50 may be a waterproof rib. With such an arrangement, when the sealing material is filled between the cover 22 and the coil connecting portion 21, the contact area between the sealing material and the annular bead can be increased compared to a planar structure, thereby improving the sealing performance.
Specifically, the waterproof structure 50 has a triangular or rectangular cross section. The cross-sectional shape of the waterproof structure 50 may be appropriately selected according to the actual structural shape of the inside of the coil body 10 to optimize the internal structure.
Specifically, the waterproof structure 50 may further include a waterproof groove and a waterproof rib, which are connected to enclose an annular structure. With such an arrangement, the contact area between the coil connecting portion 21 and the sealing material can be increased by the combination of the waterproof groove and the waterproof rib, thereby improving the sealing performance.
Specifically, the contact area between the waterproof structure 50 and the sealing material can be adjusted by setting the reasonable depth of the waterproof groove and the height of the waterproof rib, so that the sealing performance can be improved better according to actual requirements.
The second embodiment of the application provides an electronic expansion valve, which comprises an electronic coil, wherein the electronic coil is provided in the first embodiment.
