Description

Technical Field

[0001] The utility model relates to capacitor technology, in particular to a capacitor busbar assembly. Background Art

[0002] The capacitors in the prior art generally include a housing and a busbar structure. The busbar structure is accommodated in the housing, and the busbar structure has a number of lead terminals for electrical connection with external devices. In order to facilitate connection with corresponding external devices, the layout of the lead terminals of the busbar structure of some capacitors has been redesigned, resulting in a small number of lead terminals being close to the side wall where the wide side of the housing is located, thereby interfering with the side wall where the wide side of the existing housing is located. In order to solve this problem, some adopt the method of increasing the size of the housing, but this not only consumes more materials, but also increases the overall volume of the housing and the internal space, thereby increasing the space occupied by the entire capacitor and making the internal layout less compact.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figures 1 to 5As shown, the capacitor busbar assembly of the utility model includes a busbar seat 1, a first vertical body 2 and a second vertical body 3 are provided inside the busbar seat 1, a first installation area 4 is formed between the first vertical body 2 and the inner wall of the busbar seat 1, a second installation area 5 is formed between the second vertical body 3 and the inner wall of the busbar seat 1, and a third installation area 7 for placing a capacitor 6 is formed between the first vertical body 2 and the second vertical body 3.

[0021] The first vertical body 2 and the second vertical body 3 are used to separate the first contact 8 and the second contact 9, and the pins of the capacitor 6 can be respectively arranged in the first contact 8 and the second contact 9. When the capacitor 6 is installed on the first contact 8 and the second contact 9, it is installed with elastic deformation.

[0022] A first contact 8 is provided in the first installation area 4, a second contact 9 is provided in the second installation area 5, a first pin 10 is provided at one end of the capacitor 6, and a second pin 11 is provided at the other end, a receiving opening 12 for placing the first pin 10 is provided on the first contact 8, and a receiving area 13 for placing the second pin 11 is provided on the second contact 9. The first pin 10 is bent and deformed to contact and connect with the first contact 8, and the second pin 11 is elastically stressed to contact and connect with the second contact 9.

[0023] The first pin 10 is provided with a first curved section 14, a second curved section 15 and a third curved section 16. The angle between the first curved section 14 and the first pin 10 is less than 90°.

[0024] An elastic area 22 is formed between the first bending section 14 and the second bending section 15. When the first pin 10 is installed in the accommodating opening 12, the third bending section 16 is kept in contact with surface a, and the first bending section 14 is in contact with surface b, and surface b is inclined. At this time, the first bending section 14, the second bending section 15 and the third bending section 16 are kept compressed between surface a and surface b.

[0025] A first extension protrusion 17 is provided at one end of the receiving opening 12, and the third curved section 16 contacts the first extension protrusion 17. A second extension protrusion 18 is provided at the other end, and the second extension protrusion 18 contacts the first curved section 14. The first pin 10 is placed on the second extension protrusion 18. An inclined surface 19 is provided in the receiving opening 12 to guide the third curved section 16 to the lower end of the first extension protrusion 17.

[0026] The height of the first contact member 8 is higher than that of the first vertical body 2 , so that the first pin 10 can be bent under force, and the capacitor 6 is prevented from deflecting and rolling.

[0027] A spiral section 20 is provided on the second pin 11. An arc-shaped guide portion 21 is provided on the second contact member 9, and the spiral section 20 is located at the lower end of the arc-shaped guide portion 21. When the second pin 11 is installed, the spiral section 20 can be kept in contact with the arc-shaped guide portion 21, and then guided by the arc-shaped guide portion 21, it enters the accommodation area 13, keeps the spiral section 20 compressed, and is blocked by the c-surface, so that the middle of the capacitor 6 is higher.

[0028] Furthermore, when the third curved section 16 is blocked by the first extension protrusion 17, it will not be stressed upwards, and when the first pin 10 is placed on the second extension protrusion 18, the capacitor 6 will be kept moving downwards into the third mounting area 7 with the second extension protrusion 18 as a fulcrum, and the spiral section 20 will be blocked by the c-surface at the lower end of the arc-shaped guide portion 21, so that the spiral section 20 is also in a bent stress state. At the same time, the spiral section 20 is blocked by the d-surface, so that the spiral section 20 is compressed.

[0029] During installation, firstly, the first pin 10 of the capacitor 6 is vertically placed in the receiving opening 12 , and then the second pin 11 is rotated so that the second pin 11 reaches the receiving area 13 under the guidance of the arc-shaped guide portion 21 , thereby installing the capacitor 6 in a row.

[0030] In addition, the first contact member 8 and the second contact member 9 are made of conductive material, and the wires are welded on the surface, so that multiple capacitors 6 can be connected at the same time. When multiple capacitors are not needed, the redundant ones can be removed. Keeping the capacitor 6 body in a suspended state can facilitate the heat dissipation of the capacitor 6.

[0031] Connecting bolts may be provided on the side of the busbar seat 1, so that the connecting bolts can fix the first contact piece 8 and the second contact piece 9 in the busbar seat 1, and can also be used to draw out current and connect to an external line body.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
