[0024] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.
[0025] In the prior art, the processing process of capacitors is:
[0026] First, after the capacitor core is sprayed with gold, it enters the next process of empowerment and sorting, and then welding and assembly; secondly, the lead-out plugs are welded at both ends of the gold sprayed layer of the capacitor core. After welding, the electric core and at least part of the lead-out plug are installed into the shell of the capacitor; finally, epoxy resin is poured, and the amount of epoxy resin poured is controlled according to the distance (height) dimension from the epoxy resin poured to the lead-out plug in the first sample of capacitor production. Among them, the distance (height) dimension from the epoxy resin poured to the lead-out plug in the first sample of capacitor production is measured by a ruler.
[0027] It can be seen that in the process of pouring epoxy resin in the processing of the above-mentioned capacitor, the pouring amount needs to be controlled according to the distance (height) dimension from the epoxy resin pouring to the lead-out terminal plug in the first sample of capacitor production. However, it is not very convenient to measure the distance (height) dimension from the epoxy resin pouring to the lead-out terminal plug by a ruler, and the dimension measured by the ruler may have errors, resulting in inaccurate pouring amount. Finally, the height (distance) from the epoxy resin pouring to the lead-out terminal plug of each capacitor after production is different.
[0028] In order to effectively solve the above problems, the utility model provides a lead-out plug and a capacitor having the same, which will be described in detail below.
[0029] See also Figure 1 and Figure 2 According to an embodiment of the utility model, a lead-out plug is provided, the lead-out plug 1001 is used to connect with the core of the capacitor 100, the core of the capacitor 100 is connected with an external device through the lead-out plug 1001, the lead-out plug 1001 comprises: a plug body 1 and a limiting portion 2, the plug body 1 is respectively connected with the core of the capacitor 100 and the external device; the limiting portion 2 is arranged on the side wall of the plug body 1, the limiting portion 2 is used to limit the position where the packaging material 1003 is poured into the plug body 1; wherein the limiting portion 2 has a limited area, and the position where the packaging material 1003 is poured into the plug body 1 is limited within the limited area.
[0030] It can be seen that the lead-out plug provided by the utility model is provided with a plug body 1 and a limiting part 2 by simply setting the plug body 1 and the limiting part 2, and the limiting part 2 is provided on the plug body 1, and then the position of the packaging material 1003 poured into the plug body 1 is limited by the limiting part 2. At the same time, the limiting part 2 has a limited area, thereby ensuring that the packaging material 1003 can be poured into the specified area, avoiding the height (distance) of the packaging material 1003 poured into the lead-out plug 1001 being too long or too short; ensuring the accurate pouring position of the packaging material 1003, realizing the precise control of the height of the packaging material 1003 poured into the lead-out plug 1001, thereby improving the qualified rate of the capacitor 100 and ensuring the reliability of the connection between the capacitor 100 and the external circuit. In addition, by providing the limiting part 2 on the plug body 1, it is also convenient for the staff to visually observe the height (distance) of the packaging material 1003 poured into the lead-out plug 1001 or for the equipment to automatically detect the height (distance) of the packaging material 1003 poured into the lead-out plug 1001, thereby improving the efficiency of capacitor production and improving the detection efficiency. The lead-out plug has a simple structure and can effectively solve the technical problem in the prior art that the height (distance) of the lead-out plug from the capacitor to the epoxy resin cannot be accurately controlled during epoxy resin pouring.
[0031] In actual operation, after the lead-out plug 1001 is connected to the core of the capacitor 100, the connected lead-out plug 1001 and the core of the capacitor 100 are installed in the shell 1002 of the capacitor 100, and then the packaging material 1003 is poured into the shell 1002. As the packaging material 1003 is continuously poured into the shell 1002, it will be poured onto the plug body 1. When the liquid level of the packaging material 1003 rises to the defined area of the defined part 2, the pouring of the packaging material 1003 is stopped. Thus, the position where the packaging material 1003 is poured into the plug body 1 is defined within the defined area of the defined part 2.
[0032] In the specific implementation process, Figure 1 As shown, the defining portion 2 includes: a first defining portion 21 and a second defining portion 22, which are arranged on the side wall of the insert body 1 at intervals along the height direction of the capacitor 100; wherein a defined area is formed between the first defining portion 21 and the second defining portion 22.
[0033] In actual operation, the first limiting portion 21 is located below the second limiting portion 22. The first limiting portion 21 is used to determine the minimum filling height of the packaging material 1003. When the packaging material 1003 is poured to the position of the first limiting portion 21, it indicates that the packaging material 1003 has reached the specified minimum filling height. The second limiting portion 22 is used to determine the maximum filling height of the packaging material 1003. When the packaging material 1003 is poured to the position of the second limiting portion 22, it indicates that the packaging material 1003 has reached the specified maximum filling height. If the height (distance) of the packaging material 1003 poured to the lead-out plug 1001 exceeds the position of the second limiting portion 22, it indicates that the height (distance) of the packaging material 1003 poured to the lead-out plug 1001 is too long, and the capacitor 100 is an unqualified product.
[0034] In actual operation, the position where the packaging material 1003 is poured into the lead-out plug 1001 must be greater than or equal to the position of the first limiting portion 21, and lower than or equal to the position of the second limiting portion 22 (i.e., the position where the packaging material 1003 is poured into the lead-out plug 1001 must be within the limited area).
[0035] In the first embodiment of the first limiting portion 21 and the second limiting portion 22 provided in the embodiment of the present utility model, as Figure 1 As shown, the first defining portion 21 is a first defining line, the second defining portion 22 is a second defining line, and the second defining line is located above the first defining line. With such a structural arrangement, it is convenient for the staff to directly visually measure the height (distance) of the encapsulation material 1003 poured to the lead-out plug 1001 through the first defining line and the second defining line, or it is convenient for the equipment to automatically detect the height (distance) of the encapsulation material 1003 poured to the lead-out plug 1001.
[0036] In the actual working process, the first limiting line and the second limiting line are engraved on the plug body 1. The positions of the first limiting line and the second limiting line are set according to customer requirements. Usually, when the lead-out plug 1001 is produced, the first limiting line and the second limiting line are engraved on the side wall of the plug body 1 using the mold of the lead-out plug 1001.
[0037] In a second embodiment of the first limiting portion 21 and the second limiting portion 22 provided in the embodiments of the present invention, the first limiting portion 21 is a first protrusion, and the length of the first protrusion extends along the length direction of the capacitor 100; the second limiting portion 22 is a second protrusion, and the length of the second protrusion extends along the length direction of the capacitor 100; wherein the second protrusion is located above the first protrusion.
[0038] In actual working process, the first protrusion and the second protrusion are equivalent to two defining lines on the side wall of the protruding plug body 1. The positions of the first protrusion and the second protrusion are set according to customer requirements. Usually, when producing the lead-out plug 1001, the first protrusion and the second protrusion are set on the side wall of the plug body 1 using the mold of the lead-out plug 1001. In short, the first protrusion and the second protrusion are integrally formed with the plug body 1.
[0039] In actual working process, the first protrusion and the second protrusion only need to slightly protrude from the side wall of the plug body 1. Such a structural setting is adopted to facilitate the staff to directly visually observe the height (distance) of the packaging material 1003 poured to the lead-out plug 1001 through the first protrusion and the second protrusion, or to facilitate the equipment to automatically detect the height (distance) of the packaging material 1003 poured to the lead-out plug 1001.
[0040] In this embodiment, if Figure 1 and Figure 2 As shown, the plug body 1 includes: a plug-in portion 11 and a pin portion 12, the limiting portion 2 is arranged on the side wall of the plug-in portion 11, and the plug-in portion 11 is used to connect with an external device; one end of the plug-in portion 11 close to the core of the capacitor 100 is connected to the pin portion 12, and the pin portion 12 is used to connect with the core of the capacitor 100.
[0041] In the specific implementation process, Figure 2 As shown, the plug-in portion 11 includes a first plug-in piece 111 and a second plug-in piece 112, the first plug-in piece 111 and the second plug-in piece 112 are arranged opposite to each other, and the two sides of the pin portion 12 are respectively connected to the first plug-in piece 111 and the second plug-in piece 112; wherein, there are two defining portions 2, one of the two defining portions 2 is located on the side wall of the first plug-in piece 111 away from the second plug-in piece 112, and the other of the two defining portions 2 is located on the side wall of the second plug-in piece 112 away from the first plug-in piece 111.
[0042] In actual operation, the first plug-in piece 111 is connected to the second plug-in piece 112 through the pin portion 12. The end of the pin portion 12 away from the core of the capacitor 100 is located at the end of the first plug-in piece 111 close to the core of the capacitor 100 and the end of the second plug-in piece 112 close to the core of the capacitor 100.
[0043] In the specific implementation process, Figure 2 As shown, the pin portion 12 includes a first pin segment 121, a second pin segment 122 and a third pin segment 123, one end of the first pin segment 121 is connected to the plug-in portion 11, and the other end of the first pin segment 121 is respectively connected to the second pin segment 122 and the third pin segment 123, and the second pin segment 122 and the third pin segment 123 are spaced apart along the width direction of the first pin segment 121.
[0044] In the specific implementation process, Figure 1 As shown, the lead-out plug 1001 also includes: a connection portion 3, the connection portion 3 is connected to the pin portion 12, and the connection portion 3 is used to connect to the housing 1002 of the capacitor 100; the connection portion 3 at least partially includes a bending portion. With such a structural arrangement, the lead-out plug 1001 can be stably arranged in the housing 1002 of the capacitor 100 through the connection portion 3, thereby ensuring that there is no installation position between the lead-out plug 1001 and the housing 1002 of the capacitor 100, and the connection portion 3 at least partially includes a bending portion, and the installation position of the connection portion 3 and the housing 1002 of the capacitor 100 can be adjusted according to the specific installation position of the lead-out plug 1001.
[0045] In actual working process, the connecting portion 3 is connected to the first pin segment 121 of the pin portion 12 .
[0046] In the specific implementation process, there is an avoidance gap between the connecting portion 3 and the pin portion 12. Such a structural setting is adopted to ensure that the connecting portion 3 is connected to the housing 1002 of the capacitor 100.
[0047] In the specific implementation process, Figure 1 As shown, the connecting portion 3 includes: a first connecting segment 31 and a second connecting segment 32, one end of the first connecting segment 31 is connected to the plug-in portion 11, and the other end of the first connecting segment 31 is connected to one end of the second connecting segment 32, and the second connecting segment 32 is used to connect to the shell 1002 of the capacitor 100.
[0048] In actual working process, the first connecting section 31 is an arc section, and there is an arc transition between the first connecting section 31 and the second connecting section 32. With such a structural setting, the arc transition between the first connecting section 31 and the second connecting section 32 can ensure the structural stability of the connecting portion 3 and reduce the stress concentration of the connecting portion 3.
[0049] The utility model also provides a capacitor, see Figures 3 to 5The capacitor includes a capacitor core, a lead-out plug 1001, a shell 1002 and a packaging material 1003. The lead-out plug 1001 is the lead-out plug 1001 in the above embodiment. The plug body 1 of the lead-out plug 1001 is connected to the capacitor core, and at least part of the capacitor core and the lead-out plug 1001 are installed in the shell 1002; the packaging material 1003 is used to encapsulate at least part of the capacitor core and the lead-out plug 1001 in the shell 1002; wherein the position where the packaging material 1003 is poured into the plug body 1 of the lead-out plug 1001 is limited to the limiting area of the limiting part 2. With such a structural setting, the packaging material 1003 is used to encapsulate at least part of the capacitor core and the lead-out plug 1001 in the shell 1002, and the packaging material 1003 can protect at least part of the capacitor core and the lead-out plug 1001 from the influence of the external environment, such as moisture, dust, chemicals, etc. This helps to improve the weather resistance and reliability of the capacitor. In addition, by providing the limiting portion 2 on the insert body 1, the liquid level of the packaging material 1003 poured into the housing 1002 can be more clearly controlled, which is convenient for manual visual inspection or detection.
[0050] In the specific implementation process, there are two lead-out plugs 1001, which are respectively arranged at the two ends of the capacitor core, and the pins 12 of the two lead-out plugs 1001 are respectively connected to the two end surfaces of the capacitor core. The plug-in part of the lead-out plug 1001 is located above the capacitor core.
[0051] In actual operation, the lead-out plug 1001 is integrally formed, and the pin portion of the lead-out plug 1001 is connected to the capacitor core by welding.
[0052] In actual operation, the packaging material 1003 must have certain insulation properties so as to effectively prevent leakage of current between components or between components and the external environment, thereby improving the safety and stability of the circuit.
[0053] In actual working process, packaging material 1003 can be epoxy resin, polyurethane resin, silica gel and other materials. Epoxy resin is preferred. With such structural setting, epoxy resin is selected as packaging material because epoxy resin can not only encapsulate and protect at least part of capacitor core and lead-out plug 1001, but also has high mechanical strength and hardness, which can enhance the structural strength of capacitor 100 and prevent capacitor 100 from being affected by mechanical vibration or impact. Epoxy resin has excellent insulation performance, which can effectively prevent leakage of current between capacitors 100 or between capacitors 100 and external environment, thereby improving the safety and stability of the circuit.

Finally, the packaging material 1003 is poured into the shell, and when the packaging material 1003 is poured into the limited area of the limited part 2, the pouring of the packaging material 1003 is stopped, and after the packaging material 1003 is solidified, the capacitor 100 is processed.
[0056] The utility model provides a lead-out plug-in, which is used to connect with the core of the capacitor 100. The core of the capacitor 100 is connected with an external device through the lead-out plug-in 1001. The lead-out plug-in 1001 includes: a plug-in body 1 and a limiting portion 2.

[0057] It can be seen that the lead-out plug provided by the utility model is provided with a plug body 1 and a limiting part 2 by simply setting the plug body 1 and the limiting part 2, and the limiting part 2 is provided on the plug body 1, and then the position of the packaging material 1003 poured into the plug body 1 is limited by the limiting part 2. At the same time, the limiting part 2 has a limited area, thereby ensuring that the packaging material 1003 can be poured into the specified area, avoiding the height (distance) of the packaging material 1003 poured into the lead-out plug 1001 being too long or too short; ensuring the accurate pouring position of the packaging material 1003, realizing the precise control of the height of the packaging material 1003 poured into the lead-out plug 1001, thereby improving the qualified rate of the capacitor 100 and ensuring the reliability of the connection between the capacitor 100 and the external circuit. In addition, by providing the limiting part 2 on the plug body 1, it is also convenient for the staff to visually observe the height (distance) of the packaging material 1003 poured into the lead-out plug 1001 or for the equipment to automatically detect the height (distance) of the packaging material 1003 poured into the lead-out plug 1001, thereby improving the efficiency of capacitor production and improving the detection efficiency.
