Abstract
Description
Technical Field
[0001] The utility model relates to an electronic component, in particular to an electronic component suitable for surface mounting. Background Art
[0002] The current electronic components include a component body (such as a ceramic capacitor, a film capacitor, a varistor, a thermistor, etc.) and a left pin and a right pin arranged on both end surfaces of the component body. The left pin and the right pin generally include a connecting section and a vertical section. The connecting section is connected to the side of the component body, and the vertical section is connected to the lower end of the connecting section. The vertical section is used to be inserted into a circuit board and welded. The traditional way of installing such electronic components on a circuit board is: the circuit board is provided with sockets corresponding to the left pin and the right pin, and the vertical sections of the left pin and the right pin of the electronic component are inserted into the sockets of the circuit board by plug-in, so that the component body stands on the circuit board, and then the vertical sections of the left pin and the right pin are fixed on the circuit board by welding. However, this plug-in method mainly relies on manual plug-in, and the labor cost required for manual plug-in is too high, the production efficiency is low, and it is easy to make plug-in errors. Utility Model Content
[0003] The problem to be solved by the utility model is to provide an electronic component suitable for surface mounting, which can be conveniently mounted on a circuit board, reducing the labor cost of users and improving the production efficiency and assembly accuracy of the electronic component installation.
[0004] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:
[0005] An electronic component suitable for surface mounting, comprising a component body and a left pin and a right pin arranged on the component body, characterized in that: the left pin and the right pin each comprise a vertical section, a bending section and a transverse section sequentially connected from top to bottom, the upper end of the vertical section is connected to the component body, the lower end of the vertical section is exposed below the lower end surface of the component body, one end of the bending section is connected to the lower end of the vertical section, and one end of the transverse section is connected to the other end of the bending section; the transverse section of the left pin and the transverse section of the right pin are on the same plane;
[0006] The port of the bending section of the left pin and the lateral section of the left pin are both arranged toward the front end of the component body, and the port of the bending section of the right pin and the lateral section of the right pin are both arranged toward the rear end of the component body; or, the port of the bending section of the left pin and the lateral section of the left pin are both arranged toward the rear end of the component body, and the port of the bending section of the right pin and the lateral section of the right pin are both arranged toward the front end of the component body.
[0007] Since the port of the bending section of the left pin and the port of the bending section of the right pin are in opposite directions, the transverse section of the left pin and the transverse section of the right pin are in opposite directions, and the transverse section of the left pin and the transverse section of the right pin are in the same plane, so that the transverse sections of the left pin and the transverse sections of the right pin extend in opposite directions. When the electronic component is to be installed on a circuit board, it is only necessary to place the two transverse sections below the component body at the corresponding positions of the circuit board. The two transverse sections can stably support the component body, so that the component body automatically stands at the corresponding position of the circuit board, and finally the two transverse sections are fixed on the circuit board by welding.
[0008] In a preferred embodiment, the transverse section of the left pin is parallel to the transverse section of the right pin. Setting the transverse section of the left pin and the transverse section of the right pin to be parallel can provide a more stable support, so that the component body stands more stably on the circuit board, avoiding the problem of movement or looseness caused by unstable pins.
[0009] In a preferred embodiment, the length of the lower end of the vertical section exposed below the lower end surface of the element body is 0.5 mm-3 mm.
[0010] In a preferred embodiment, the bending angle of the bending section is 90°.
[0011] In the preferred embodiment, the shape of the bending section is L-shaped, U-shaped, V-shaped, W-shaped or m-shaped. Of course, the bending section can also be designed into other shapes according to customer needs. Designing the shape of the bending section into L-shaped, U-shaped, V-shaped, W-shaped or m-shaped can increase the curvature of the pin, improve the flexibility and elasticity of the pin, so that it can better adapt to the changes of thermal expansion and contraction during the welding process, reduce the influence of welding stress on the pin, and improve the reliability and stability of the electronic component.
[0012] In a further preferred embodiment, the bending section has at least two bending arms, and the bending arms are parallel to the lower end surface of the component body. This arrangement can increase the three-dimensional stability of the electronic component, prevent the component body from shaking or swinging during assembly and transportation, and thus reduce the risk of damage.
[0013] In a further preferred embodiment, each of the bending arms is on the same plane. This arrangement can further increase the stability and three-dimensional positioning accuracy of the electronic component, ensure the correspondence between the pins and the circuit board, and avoid the installation skew problem caused by uneven pin spacing or misalignment.
[0014] In a preferred embodiment, the inner end of the bending section is connected to the lower end of the vertical section, and one end of the transverse section is connected to the outer end of the bending section; or the outer end of the bending section is connected to the lower end of the vertical section, and one end of the transverse section is connected to the inner end of the bending section. The above-mentioned inside and outside are defined as: based on the center of the lower end surface of the element body, the side close to the center of the lower end surface of the element body is the inside, and the side away from the center of the lower end surface of the element body is the outside. Through this arrangement, more connection position modes of the bending section and the transverse section are added.
[0015] Compared with the prior art, the utility model has the following advantages:
[0016] The utility model can conveniently install electronic components on the corresponding positions of the circuit board by SMT welding by changing the molding method of the left and right pins, thereby reducing the labor cost of users, improving the production efficiency and assembly accuracy of electronic component installation, and better adapting electronic components to the circuit board surface mounting / reflow soldering process. In addition, in the production process of the circuit board, the steps of forming the jack on the circuit board can also be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] Example 1
[0031] like Figure 1-6 As shown, the electronic component adapted for surface mounting in this embodiment includes a component body 1 and a left pin 2 and a right pin 3 arranged on the component body 1. The left pin 2 and the right pin 3 each include a vertical section 21, a bending section 22 and a transverse section 23 connected in sequence from top to bottom. The upper end of the vertical section 21 is connected to the component body 1, and the lower end of the vertical section 21 is exposed below the lower end surface of the component body 1. One end of the bending section 22 is connected to the lower end of the vertical section 21, and one end of the transverse section 23 is connected to the other end of the bending section 22; the transverse section 23 of the left pin 2 and the transverse section 23 of the right pin 3 are in the same plane; the port of the bending section 22 of the left pin 2 and the transverse section 23 of the left pin 2 are both arranged toward the rear end of the component body 1, and the port of the bending section 22 of the right pin 3 and the transverse section 23 of the right pin 3 are both arranged toward the front end of the component body 1.
[0032] Usually, a thin film inner core is provided in the component body 1, and the upper ends of the left pin 2 and the right pin 3 are both connected to the thin film inner core.
[0033] Since the port of the bending section 22 of the left pin 2 and the port of the bending section 22 of the right pin 3 are in opposite directions, the transverse section 23 of the left pin 2 and the transverse section 23 of the right pin 3 are in opposite directions, and the transverse section 23 of the left pin 2 and the transverse section 23 of the right pin 3 are in the same plane, so that the transverse sections 23 of the left pin 2 and the transverse sections 23 of the right pin 3 extend in opposite directions. When such an electronic component is to be installed on a circuit board 4, it is only necessary to place the two transverse sections 23 below the component body 1 at the corresponding positions of the circuit board 4. The two transverse sections 23 can stably support the component body 1, so that the component body 1 automatically stands at the corresponding position of the circuit board 4, and finally the two transverse sections 23 are fixed on the circuit board 4 through two welding points 5 by welding.
[0034] The length of the lower end of the vertical section 21 exposed below the lower end surface of the element body 1 is 0.5 mm to 3 mm.
[0035] The transverse section 23 of the left pin 2 is parallel to the transverse section 23 of the right pin 3. Setting the transverse section 23 of the left pin 2 and the transverse section 23 of the right pin 3 to be parallel can provide more stable support, so that the component body 1 stands more stably on the circuit board 4, avoiding the problem of movement or looseness caused by unstable pins.
[0036] The shape of the bending section 22 is U-shaped. Of course, the bending section 22 can also be designed into other shapes according to customer needs. Designing the shape of the bending section 22 into a U-shape can increase the curvature of the pin, improve the flexibility and elasticity of the pin, so that it can better adapt to the changes of thermal expansion and contraction during the welding process, reduce the influence of welding stress on the pin, and improve the reliability and stability of the electronic component.
[0037] The bending section 22 has two bending arms 221, and the bending arms 221 are parallel to the lower end surface of the component body 1. This arrangement can increase the three-dimensional stability of the electronic component, prevent the component body 1 from shaking or swinging during assembly and transportation, and thus reduce the risk of damage.
[0038] Each of the bending arms 221 is on the same plane. This arrangement can further increase the stability and three-dimensional positioning accuracy of the electronic component, ensure the corresponding relationship between the pins and the circuit board 4, and avoid the installation deflection problem caused by uneven pin spacing or misalignment.
[0039] The inner end of the bending section 22 is connected to the lower end of the vertical section 21, and one end of the transverse section 23 is connected to the outer end of the bending section 22. The above definition of inside and outside is: based on the center of the lower end surface of the component body 1, the side close to the center of the lower end surface of the component body 1 is the inside, and the side away from the center of the lower end surface of the component body 1 is the outside. Through this arrangement, more connection position modes of the bending section 22 and the transverse section 23 are added.
[0040] Example 2
[0041] like Figure 7 As shown, the difference between the electronic component adapted for surface mounting in this embodiment and that in embodiment 1 is as follows:
[0042] The port of the bending section 22 of the left pin 2 and the transverse section 23 of the left pin 2 are both arranged toward the front end of the component body 1, and the port of the bending section 22 of the right pin 3 and the transverse section 23 of the right pin 3 are both arranged toward the rear end of the component body. The outer end of the bending section 22 is connected to the lower end of the vertical section 21, and one end of the transverse section 23 is connected to the inner end of the bending section 22.
[0043] Example 3
[0044] like Figure 8-12As shown, the difference between the electronic component adapted for surface mounting in this embodiment and that in embodiment 1 is as follows:
[0045] The left pin 2 and the right pin 3 each include a vertical section 21, a bending section 22 and a transverse section 23 which are sequentially connected from top to bottom. The bending section is in an L-shape, and the bending angle of the bending section is 90°.
[0046] In addition, it should be noted that the names of the various parts of the specific embodiments described in this specification may be different, and any equivalent or simple changes made based on the structure, features and principles described in the utility model patent concept are included in the protection scope of the utility model patent. The technical personnel of the technical field to which the utility model belongs can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
