It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1 to 5, a first embodiment of the present invention provides an electronic coil, which includes a coil main body 10, a plug wire portion 20, a circuit board 30 and a support portion 40, wherein the plug wire portion 20 is disposed on the coil main body 10, the plug wire portion 20 includes a coil connecting portion 21 and a cover 22, a pin 23 is disposed on the coil connecting portion 21, and the cover 22 covers the coil connecting portion 21. The circuit board 30 is inserted into the pin 23, the support portion 40 is disposed on the coil connecting portion 21, at least a portion of the support portion 40 and the circuit board 30 are attached to each other, the support portion 40 is used for supporting the circuit board 30, and a support surface of the support portion 40 abuts against 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 formed through the pin 23, and the pin 23 and the supporting portion 40 are arranged at an interval. After the wiring board 30 is inserted into the pin 23, the wiring board 30 is moved to a position where it is attached to the support portion 40, so that the wiring board 30 is supported by the support portion 40, and the length of the support portion 40 is the gap between the wiring board 30 and the coil connecting portion 21. Due to the existence of the gap, in order to connect the circuit board 30 and the pin 23, welding is carried out at the through hole, welding operation is carried out at one side of the circuit board 30, welding liquid flows from one side of the circuit board 30 to the other side, and thus the reliability of soldering between 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 soldering reliability between the circuit board 30 and the pins 23 of the electronic coil in the prior art.
In the present embodiment, the supporting portion 40 includes a plurality of supporting columns, and the supporting columns are arranged at intervals. By adopting the structure, the stability of the support can be improved, so that a gap is stably ensured between the circuit board 30 and the coil connecting part 21, the welding liquid on one side of the circuit board 30 can be better ensured to flow into the other side of the circuit board 30 through the gap between the through hole and the contact pin 23, and the welding firmness is effectively ensured. Specifically, the number of the support columns in this embodiment may be 4, and the 4 support columns are located at four vertex angles of the parallelogram, and the structural layout is adopted, so that the stability of the support can be improved. Specifically, the pins 23 are plural, 2 supporting posts are located on the upper side of the pins 23, and 2 supporting posts are located on the lower side of the pins 23.
In particular, the cross section of the support column can be circular or rectangular, that is, the support column can 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, 1mm ≦ h ≦ 4mm in the present embodiment. Specifically, when the height of the support portion 40 is less than 1mm, the gap between the circuit board 30 and the coil connecting portion 21 is made too small, which makes it inconvenient for the soldering liquid to flow from one side of the circuit board 30 to the other side; when the height of the support portion 40 is larger than 4mm, the gap between the wiring board 30 and the coil connecting portion 21 becomes excessively large, which is disadvantageous to the compactness of the entire structure.
In the present embodiment, the coil connecting portion 21 includes a case connecting portion 211 and a wire connecting portion 212, the wire connecting portion 212 is disposed to protrude from the case connecting portion 211, the case 22 is disposed on the case connecting portion 211, and the pin 23 is disposed 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 pin 23 is located in the annular structure. With this arrangement, an annular structure is provided around the plurality of pins 23, and generally, a sealing material (typically, epoxy resin) is filled between the housing 22 and the coil connecting portion 21 to perform sealing. This annular structure mainly used increase and sealing material between area of contact to improve the sealing performance here, thereby can avoid the phenomenon that takes place to drop between sealing material and the coil connecting portion 21 better, thereby play waterproof effect better, avoid rivers to 23 departments of contact pin. Specifically, the wire connecting portion 212 has a mounting surface thereon, 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 groove. With this 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 coil connecting portion can be increased due to the presence of the annular waterproof groove as compared with the planar structure, thereby improving the sealing performance.
Specifically, the waterproof structure 50 may be a waterproof rib. With this arrangement, when the sealing material is filled between the cover case 22 and the coil connecting portion 21, the contact area between the sealing material and the portion can be increased due to the presence of the annular bead as compared with the planar structure, thereby improving the sealing performance.
Specifically, the cross section of the waterproof structure 50 is triangular or rectangular. The 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, and the waterproof groove and the waterproof rib are connected to form a ring structure. With this arrangement, the contact area between the coil connecting portion 21 and the sealing material can be increased even by the combination of the waterproof groove and the waterproof rib, and the sealing performance can be improved more effectively.
Specifically, the depth of the reasonable waterproof groove and the height of the waterproof rib can be set to adjust the contact area between the waterproof structure 50 and the sealing material, so that the sealing performance can be better improved according to actual requirements.
