Description

Technical Field

[0001] This utility model belongs to the field of capacitor technology, and specifically relates to a capacitor potting positioning fixture. Background Technology

[0002] Film capacitors have advantages such as non-polarity, high insulation resistance, excellent frequency characteristics, low loss, good self-healing properties, and resistance to open-circuit failure, and are widely used in home appliances, new energy, and electric vehicles.

[0003] Chinese patent CN217847707U3 discloses a potting and encapsulation fixture for radial lead-out film capacitors. Because the encapsulation fixture uses a potting mold and tooling for demolding and encapsulation, the batch consistency of the products is good. Furthermore, by fixing the core position and lead spacing through the potting mold and positioning tooling, the core position and lead spacing can be effectively guaranteed to be centered and the lead spacing to meet the requirements. The encapsulated product has a smooth and flat appearance.

[0004] However, this packaging fixture has the following problems:

[0005] ① The spacing between the capacitor electrodes cannot be changed;

[0006] ② The length of the capacitor electrodes cannot be changed; Utility Model Content

[0007] To solve the above problems, this utility model provides a capacitor potting positioning fixture, characterized in that: it includes a base plate, a crossbar, and a pad; the base plate has a U-shaped cross section, and the crossbar is installed across the top of the base plate; the pad is installed at the bottom of the base plate.

[0008] Furthermore, the crossbar is provided with two types of through holes: mounting holes and positioning holes. The mounting holes are located at the left and right ends and are installed on the base plate with screws. The positioning holes are located in the middle and have a diameter slightly larger than the diameter of the capacitor's screw electrode. After the electrode passes through the positioning hole of the crossbar, it is tightened by a nut.

[0009] Furthermore, a pad is located between the capacitor and the base plate, and the number of pads is set as needed.

[0010] Furthermore, the pad has a through hole, and the bottom of the base plate has a threaded hole. The threaded hole on the bottom of the base plate, the through hole on the pad, and the capacitor mounting lug hole correspond to each other. The fastening screw passes through the capacitor mounting lug, then through the pad, and finally engages with the threaded hole on the base plate.

[0011] Furthermore, the positioning hole spacing of the crossbar has multiple specifications. Different crossbar hole spacings correspond to different capacitor electrode spacings.

[0012] Furthermore, the pads come in various thicknesses. When different electrode exposure heights are required, the thickness or number of pads can be varied to ensure that the capacitor exposure height reaches the target value.

[0013] Furthermore, the base plate is made of aluminum alloy or fiberglass board. It is lightweight, rigid, and has high positioning accuracy.

[0014] Furthermore, a crossbar is installed at regular intervals on the base plate.

[0015] This utility model has the following beneficial effects:

[0016] 1) Ensure the spacing of the capacitor lead screws by using crossbars with different positioning hole spacings;

[0017] 2) Control the exposed length of the capacitor electrodes by using pads of different numbers or thicknesses;

[0018] 3) One set of fixtures can accommodate multiple capacitors for positioning at the same time, improving production efficiency. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-3 This utility model provides a technical solution: a capacitor potting positioning fixture, characterized in that: it includes a base plate 1, a crossbar 2 and a pad 4, the crossbar 2 is U-shaped in cross section, and the crossbar 2 is installed across the top of the base plate 1; the pad 4 is installed at the bottom of the base plate 1.

[0026] Two types of through holes are provided on the crossbar 2: mounting holes and positioning holes. The mounting holes are located at the left and right ends and are installed on the base plate 1 by screws. The positioning holes are located in the middle and have a diameter slightly larger than the diameter of the screw electrode of the capacitor 3. After the electrode passes through the positioning hole of the crossbar 2, it is tightened by a nut.

[0027] The pad 4 is located between the capacitor 3 and the base plate 1. The number of pads 4 is set as needed.

[0028] The pad 4 has a through hole, and the bottom of the base plate 1 has a threaded hole. The threaded hole at the bottom of the base plate 1, the through hole in the pad 4, and the mounting lug hole of the capacitor 3 correspond to each other. The fastening screw passes through the mounting lug of the capacitor 3, then through the pad 4, and finally engages with the threaded hole in the base plate 1 for fastening.

[0029] The positioning hole spacing of crossbar 2 has multiple specifications. Different crossbar hole spacings correspond to different capacitor electrode spacings.

[0030] The thickness of the pad 4 is available in several specifications. When different electrode exposure heights are required, the thickness or number of pads can be changed to ensure that the capacitor exposure height reaches the target value.

[0031] The base plate 1 is made of aluminum alloy or fiberglass board. It is lightweight, rigid, and has high positioning accuracy.

[0032] A crossbar 2 is installed on the base plate 1 at regular intervals.

[0033] Working principle: When using this anti-clogging hydraulic screen, if... Figure 1-3 As shown, a crossbar 2 with a suitable positioning hole spacing is installed on the base plate 1. The capacitor 3 to be potted is placed below the crossbar 2, and the screw of the capacitor 3 to be potted passes through the positioning hole of the crossbar 2. Then, a pad 4 of suitable thickness is placed between the capacitor 3 to be potted and the base plate 1. The screw passes through the mounting ear of the capacitor 3, the pad 4 and the threaded hole of the base plate 1 for a tight fit. At the same time, the nut is tightened to secure the screw of the capacitor 3 to be potted through the positioning hole of the crossbar 2. After the fixture is used to fix the capacitor 3 to be potted, the potting operation is performed.
