Fig. 1 shows a schematic structural diagram of a main body of a secondary sealing glue-pouring type single capacitor according to an embodiment of the present disclosure. As shown in fig. 1, 2 and 3, the secondary sealing potting type single capacitor includes: the capacitor comprises a shell 100 and a capacitor body 200, wherein a cavity is arranged in the shell 100, and one end of the shell is provided with an opening. The cavity is used for installing capacitor body 200, and the shape of cavity and capacitor body 200's shape phase-match, and the inner wall of cavity and the lateral wall of capacitor body 200 are laminated mutually. Capacitor body 200 includes capacitor main body 210 and pole pin 220, and capacitor main body 210 and pole pin 220 are fixed connection, and capacitor main body 210 and pole pin 220 are electrically connected. Needle 220 extends out of the cavity of housing 100 from an opening in housing 100. Glue is poured into one side of the main body 100 close to the opening of the shell 100, and the glue seals the capacitor main body 210 in the capacitor body 200 inside the cavity of the shell 100. The main body of the housing 100 is columnar, and the outer surface of the housing 100 is provided with a reference surface 110, and the reference surface 110 is a plane.

Here, it should be noted that, when the secondary sealing potting single capacitor according to the embodiment of the present disclosure is mounted, the reference surface 110 is provided in a planar shape, so that the secondary sealing potting single capacitor can be attached to a circuit board to be soldered when the secondary sealing potting single capacitor is soldered to the circuit board.

The secondary sealing glue-pouring type single capacitor of the embodiment of the disclosure wraps the capacitor body 200 through the shell 100, a cavity with the same shape as the capacitor body 200 is arranged in the shell 100, and an opening is arranged at one end of the shell, and the opening is used for enabling the capacitor body 200 to pass through the opening and be installed in the cavity. Capacitor body 200, in turn, includes a capacitor body 210 for storing and discharging electrical current and a pole pin 220 for conducting electrical current. The height of the capacitor body 210 is not less than the depth of the cavity of the housing 100, so that the highest point of the capacitor body 210 is spaced from the opening of the housing 100 for filling glue, and the pin 220 can extend out of the cavity of the housing 100 from the opening of the housing 100 for welding the pin 220 to the circuit board. After the capacitor body 200 is mounted in the housing 100, the outer wall of the capacitor body 200 is tightly attached to the inner wall of the cavity of the housing 100, so that the capacitor body 200 can be stably mounted in the cavity of the housing 100. The outer surface of the shell 100 is provided with a reference surface, and the reference surface is a plane, compared with the mode that the side surface of the shell 100 is cylindrical, the setting mode is more convenient for the shell 100 and the capacitor body 200 to carry out relative angle positioning, and the reference surface which is a plane can be directly attached to a circuit board or a component, and the like, so that the rolling of the secondary sealing glue filling type single capacitor in the embodiment of the disclosure can be prevented to a greater extent. In conclusion, the secondary sealing glue filling type single capacitor disclosed by the embodiment of the disclosure optimizes the operation performance of the process.

In a possible implementation manner, the outer surface of the housing 100 further includes an arc-shaped surface 120, and the arc-shaped surface 120 is fixedly connected with the reference surface 110. Referring to fig. 1 or 6, the section of the arc-shaped surface 120 and the reference surface 110 along the opening direction of the housing 100 is "D" shaped or "t" shaped.

Here, it may also be noted that, as shown in fig. 1, 5, 6 or 7, when the capacitor body 200 is a single capacitor body, the internal cavity of the case 100 may have a cylindrical or square cylindrical shape, and the shape of the internal cavity is determined according to the kind of the capacitor body 200. When capacitor body 200 is a two-part capacitor body, the shape of the cavity of housing 100 matches the shape of the two-part capacitor body, for example: the inner cavity of the housing 100 has a shape in which two or more cylinders are circumscribed or two or more square columns are connected. It is further noted herein that when capacitor body 200 is cylindrical and is classified as a two-piece capacitor, the centers of the two or more cylinders in housing 100 are aligned.

In a possible implementation manner, the pole pin 220 on the capacitor body 200 is bent to facilitate glue filling and welding with a circuit board, and may also be placed to contaminate the pole pin 220 when glue is filled. Because the part of the pole pin 220, which needs to be welded with components such as a circuit board, is bent outside the opening of the shell 100, the top opening of the shell 100 is completely exposed, and any part of the top opening of the shell 100 exposed outside can be used as a pouring point, so that pouring is more convenient

As shown in fig. 1 or fig. 4, in a possible implementation, the bending direction may also be opposite to the reference surface 110, and may also be arranged away from the reference surface 110. This arrangement may facilitate the relative angular positioning between the housing 100 and the capacitor body 200. When the height of the capacitor body 210 is less than the depth of the cavity on the housing 100, the housing 100 in the bending direction of the pole pin 220 is provided with the placing groove 130, the placing groove 130 is disposed adjacent to the opening on the housing 100, and the placing groove 130 is disposed through the sidewall of the housing 100. The pole needle 220 after being bent ninety degrees is placed in the placement slot 130. The bending position of the pole needle 220 can be freely adjusted by the placing groove 130.

Furthermore, in a possible implementation, the bending angle of pole needle 220 ranges from thirty degrees to ninety degrees, and when the bending angle of pole needle 220 is below thirty degrees, pole needle 220 cannot be effectively prevented from being contaminated. Further, in another possible implementation, the bending angle of pole needle 220 is ninety degrees, and when the bending angle of pole needle 220 is ninety degrees, the contamination of pole needle 220 can be prevented to the greatest extent.

Here, it should be noted that in mass production, the bending of the pole pin 220 should be accomplished using a capacitor high-speed automatic pin bending apparatus.

In one possible implementation, the housing 100 is provided with a positive mark and a negative mark, and the positive mark and the negative mark are integrally formed with the housing 100. The positive and negative poles can be more conveniently identified by adding the positive marks and the negative marks.

Here, it should be noted that the opening positions of the positive and negative marks are determined according to the positions of the positive and negative electrodes of the capacitor body 200, and the opening heights of the positive and negative marks are not limited, and may be far from the opening of the case 100 or close to the opening of the case 100. Here, it should be further noted that the positive and negative marks may be a relief mark, a gravure mark, or a combination of a relief mark and a relief mark, which is not limited herein.

Here, it should be further noted that the housing 100 may be made of engineering plastics, polycarbonate, polypropylene, soluble polytetrafluoro-elastomer, injection-molded rubber, and the like, and is not limited thereto. Thereby, the positive mark, the negative mark and the housing 100 can be integrally formed through an injection molding process. Therefore, the manufacturing process is reduced, and the working procedures of processing the positive marks and the negative marks after injection molding are reduced.

In one possible implementation, the pole pin 220 includes a positive pole pin 221 and a negative pole pin 222, and the positive pole pin 221 and the negative pole pin 222 are different in length of being exposed out of the capacitor main body 210, the positive pole pin 221 is exposed out of the capacitor main body 210 more, the negative pole pin 222 is exposed out of the capacitor main body 210 less, the positive pole pin 221 is electrically connected with the positive pole of the capacitor main body 210, and the negative pole pin 222 is electrically connected with the negative pole of the capacitor main body 210. When the capacitor body 200 is mounted, the positive electrode pin 221 is located on the positive label side, and the negative electrode pin 222 is located on the negative label side. Through setting the pole pins 220 to different lengths, the identification of the positive and negative poles of the secondary sealing glue-pouring type single capacitor in the embodiment of the present disclosure can be facilitated, and according to the knowledge of those skilled in the art, the positive pole pin 221 is installed on one side of the positive pole, and the negative pole pin 222 is installed on one side of the negative pole, so that the identification of those skilled in the art can be facilitated.

In one possible implementation, the inner wall of the cavity on the housing 100 is attached to the side wall of the capacitor body 200. Thereby, the positioning deviation between the case 100 and the capacitor body 200 is prevented, and the capacitor body 200 can be prevented from moving when the glue is poured.

In one possible implementation, the capacitor body 200 is a super capacitor, and the super capacitor includes any one of a single capacitor, a double capacitor, or a multi-capacitor.

In one possible implementation, the junction of the reference surface 110 and the arc surface 120 on the outer surface of the housing 100 is provided with a chamfer. Set up the chamfer on arcwall face 120 and reference surface 110 and can increase the intensity stress of shell 100, also can avoid moulding plastics the closed angle to make the manufacturing degree of difficulty reduce, also can alleviate the weight of shell 100 to a certain extent, increase the quality of use of shell 100, improve the life of shell 100.

As shown in fig. 1 or fig. 3, in one possible implementation, the capacitor main body 210 includes a rubber plug 211, an aluminum shell 212, and a core package, wherein the aluminum shell 212 is hollow and has an opening at one end, and the core package is placed into the hollow interior of the aluminum shell 212 from the opening and is fixedly connected to a side wall of the aluminum shell 212. The rubber plug 211 is arranged at the opening of the aluminum shell 212, and the rubber plug 211 is fixedly connected with the inner wall of the aluminum shell 212 at the opening and seals the opening of the aluminum shell 212. The polar needle 220 penetrates through the rubber plug 211, one end far away from the rubber plug 211 extends out of the rubber plug 211, and the polar needle 220 close to one end of the aluminum shell 212 is electrically connected with the core bag. Because the height of the capacitor body 200 is less than the height of the cavity of the housing 100, the rubber plug 211 is located inside the cavity of the housing 100, and the rubber plug 211 is spaced from the opening of the housing 100. After filling, the glue should completely cover the side of the rubber plug 211 near the opening of the housing 100. By the rubber plug 211, the electrolyte in the core pack can be further prevented from leaking.

Here, it should be noted that a plurality of capacitor bodies 200 to which the housings 100 are mounted may be placed on the linear groove jig 300 and filled with glue. The linear groove jig 300 is in a U-shaped plate shape with two sides having different lengths, the capacitor body 200 enters the linear groove jig along the U-shaped opening, and the reference surface 110 is tightly attached to one side of the long plate of the U-shaped plate. The plurality of capacitor bodies 200 are naturally closely arranged.

Further, in a possible implementation manner, a boss 2111 is provided on the rubber plug 211 covering one side of the glue solution, and a groove is provided on the boss 2111. The groove penetrates through the boss 2111 along the diameter direction of the boss 2111, the groove penetrates through the boss 21111 along the thickness of the boss 2111, and the pole pin 220 penetrates through the groove. The boss 2111 is arranged on the rubber plug 211, the groove is formed in the boss 2111, the rubber plug 211 can be mounted more conveniently, and the rubber plug 211 can be adjusted more conveniently when the rubber plug 211 is needed. Meanwhile, by arranging the boss 2111 and forming the groove on the boss 2111, the thickness of the rubber plug 211 with the groove can be prevented from being too thin compared with a method of directly forming the groove on the rubber plug 211, so that the service life and the use experience are influenced.

Here, it should be noted that the rubber plug 211 is integrally formed by injection molding, and the rubber plug 211 is integrally formed at one time by providing a mold having the same shape and size as the rubber plug 211. Therefore, the injection molding process of the rubber plug 211 is optimized, and the process of separately adding the material digging on the boss 2111 of the rubber plug 211 is not needed. Meanwhile, the reduction of the service life of the rubber plug 211 caused by the over-thin thickness of the groove of the rubber plug 211 due to the excessive digging of the materials is avoided.

Here, it should also be noted that when the linear groove jig 300 is mass-produced for use, the linear groove jig 300 is placed on the glue gun. Here, it should also be noted that in mass production, the glue can be poured by a high-speed automatic glue-pouring machine.

Here, it should be noted that the adhesive solution may be a two-component silicone rubber, a two-component epoxy resin, a one-component adhesive solution, or a multi-component adhesive solution, or may be a photocurable adhesive solution, in addition to the fast curing type. However, a fast curing glue should be preferred, which can improve the production efficiency to the greatest possible extent. Here, it should be noted that after the fast curing type glue is selected, the surface should be selected to be hydrophobic.
