The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference below Figure 1-Figure 4 , the implementation of the capacitor with pin positioning proposed in the embodiment of the utility model is described in detail.

[0031] The capacitor with pin positioning according to the embodiment of the utility model comprises: a housing 1 , a core 2 and a positioning member 3 .

[0032] Specifically, the shell 1 defines an installation cavity 11 with an open opening; the core 2 is arranged in the installation cavity 11, and the first pin 21 and the second pin 22 of the core extend out of the installation cavity 11 through the open opening; the positioning member is installed in the installation cavity 11, and the positioning member 3 defines a first through hole 31 and a second through hole 32, and the first through hole 31 and the second through hole 32 are correspondingly mounted on the first pin 21 and the second pin 22.

[0033] That is to say, the core 2 is installed in the installation cavity 11 of the shell 1 and the pins of the core 2 are led out of the installation cavity 11 through the open mouth of the installation cavity 11, the positioning member 3 is installed in the installation cavity 11, and the first through hole 31 and the second through hole 32 on the positioning member 3 are correspondingly mounted on the first pin 21 and the second pin 22 of the core 2, thereby positioning the first pin 21 and the second pin 22.

[0034] Thus, the core 2 is installed in the mounting cavity 11 of the shell 1 and the pins of the core 2 are led out of the mounting cavity 11, and the positioning member 3 is installed in the mounting cavity 11 and the pins of the core 2 are extended out of the mounting cavity 11 from the through holes on the positioning member 3, thereby positioning the pins; the capacitor with pin positioning can position the pins of the core, occupies a small space, is convenient for the miniaturization of the capacitor as a whole, and is conducive to reducing costs.

[0035] For the installation of the positioning member 3, the inner wall of the installation cavity 11 defines a first connection portion 12, and the positioning member 3 defines a second connection portion 33, and the second connection portion 33 is suitable for connecting the first connection portion 12 so that the positioning member 3 is installed in the housing 1. It can be understood that the connection between the first connection portion 12 and the second connection portion 33 can facilitate the installation of the positioning member 3 in the housing 1, so that the first through hole 31 and the second through hole 32 can be inserted into the first pin 21 and the second pin 22 one by one. Among them, the positioning member 3 can be set in a long strip shape, and the second connection portion 33 is set one by one at both ends of the positioning member 3 along the length direction thereof.

[0036] The first connection part 12 and the second connection part 33 are snap-connected. It can be understood that the snap-connection between the first connection part 12 and the second connection part 13 facilitates the rapid installation of the positioning member 3, thereby improving the assembly efficiency of the positioning member 3.

[0037] Further, the first connection portion 12 has a groove 121 arranged opposite to each other, and the second connection portion 33 has a protrusion 332 arranged opposite to each other, and the protrusion 332 is suitable for being snapped into the groove 121 to snap-connect the first connection portion 12 with the second connection portion 33. It can be understood that the positioning member 3 can be quickly and firmly installed in the installation cavity 11 through the cooperation of the groove 121 and the protrusion 331, thereby ensuring the reliability of the positioning of the first pin 21 and the second pin 22, and at the same time improving the installation efficiency of the positioning member 3.

[0038] For supporting the shell 1 and the core 2, the positioning member 3 includes a supporting member 34 arranged opposite to each other. When the second connecting portion 33 is connected to the first connecting portion 12, the supporting member 34 abuts against the inner wall of the installation cavity 11 and the core 2. It can be understood that when the positioning member 3 is installed in the installation cavity 11, the supporting member 34 abuts against and supports the shell 1 from the inner wall of the shell 1, thereby strengthening the strength of the shell 1 at the open mouth. At the same time, when the supporting member 34 abuts against the core 2, the core 2 can be initially positioned, which is convenient for the subsequent potting of the core 2. Among them, the shell 1 can be cylindrical, and the supporting member 34 can be arranged to match the two arc surfaces of the inner wall of the shell 1 at the matching position with the shell 1.

[0039] For potting of the core 2, the first through hole 31 extends downwardly out of a column 35, and the side of the column 35 has an opening 351. The column 35 is suitable for extending into the axial hole 23 of the core 2 so that the potting material enters the axial hole 23 from the opening 351, and the first pin 21 passes through the through hole through the axial hole 23. It can be understood that the column 35 extending downward through the first through hole 31 extends into the axial hole 23 of the core 2, so that the relative position of the core 2 and the housing 1 is initially fixed, which is convenient for pouring the potting material from the opening 351 and leading it out of the axial hole 23 through the first pin 21, which can reduce the number of bending times of the first pin 21, making installation easier, and at the same time, it can facilitate the positioning of the first pin 21 by the first through hole 31.

[0040] The bottom of the protrusion 331 is provided with an inclined surface 332. It can be understood that the inclined surface at the bottom of the protrusion 331 can facilitate the protrusion 331 to be directly pressed into the groove 121, so that the positioning block can be quickly installed on the housing 1. The distance between the two protrusions 331 and the distance between the two grooves 121 can be consistent.

[0041] For limiting the positioning member 3, the positioning member 3 is further provided with a limiting platform 36, and a limiting groove 122 is provided above the groove 121, and the limiting platform 36 is suitable for cooperating with the limiting groove 122 to limit the positioning member 3. It can be understood that through the cooperation of the limiting platform 36 and the limiting groove 122, the installation gap between the positioning member 3 and the housing 1 can be eliminated, so as to better position the first pin 21 and the second pin 22. Among them, the limiting platform 36 can be integrally formed at the middle position above the protrusion 331, and the limiting groove 122 can be integrally formed at the middle position above the groove 121.

[0042] As for the first through hole 31 and the second through hole 32, the first through hole 31 and the second through hole 32 are both convexly arranged in the direction of leading out the first pin 21 and the second pin 22. It can be understood that, through the convex arrangement of the first through hole 31 and the second through hole 32, the matching section between the first through hole 31 and the second through hole 32 and the first pin 21 and the second pin 22 is lengthened, so as to better support and position the first pin 21 and the second pin 22, and at the same time, the overall arrangement of the positioning member 3 can be made thinner, so as to reduce the occupied space of the positioning member 3.
