Description

Technical Field

[0001] The utility model relates to the technical field of capacitor guide needles, in particular to a capacitor guide needle with a stable structure. Background Art

[0002] A capacitor is a component that can store electric charge and is one of the most commonly used electronic components. Any two insulated and closely spaced conductors (including wires) form a capacitor, which is connected to other circuits through capacitor pins. The basic function of a capacitor is charging and discharging, but many circuit phenomena derived from this basic charging and discharging function give capacitors a variety of different uses. Capacitor pins are one of the important components of a capacitor. The capacitor pins are in direct contact with the electrolyte inside the capacitor, and they conduct electricity and transport electrons.

[0003] Most existing capacitor guide pins are simple in design, consisting of two cylindrical rods with different diameters. The contact between the capacitor guide pin and the internal filling of the capacitor is not stable enough, and it is easy to loosen after long-term use, causing the capacitor to fall off the circuit board and fail.

[0004] Among them, the prior art CN205751877U capacitor guide pin is provided with at least one circle of grooves with a semicircular cross-section on the side of the guide pin stem, the guide pin tongue is in the shape of a rectangular sheet, and one of the largest surfaces of the guide pin tongue is provided with a plurality of reinforcement leaves, and the reinforcement leaves are all bent toward one end of the guide pin foot. When producing capacitors, the guide pin tongues of two capacitor guide pins can be fixed inside the capacitor, the guide pin stem is fixed at the end cover, and the reinforcement leaves of the two guide pin tongues are distributed on different sides. The reinforcement leaves improve the connection tightness between the guide pin tongue and the capacitor filler, which can effectively prevent the capacitor guide pin from loosening inside the capacitor, thereby solving the above technical problems. However, there is a certain probability that the capacitor guide pin will have poor contact due to the small contact area with the contact; therefore, it does not meet the existing needs. In this regard, we propose a capacitor guide pin with a stable structure. Utility Model Content

[0005] The utility model aims to provide a capacitor guide pin with a stable structure to solve the problem that the capacitor guide pin proposed in the above background technology has a certain probability of causing poor contact due to a small contact area with the contact point.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a capacitor guide needle with a stable structure, comprising a capacitor, support rods are arranged on both sides inside the capacitor, the upper end surface of the support rod is fixedly connected to the guide needle through a mounting plate, limiting holes are arranged in the middle of the front end surface and the rear end surface of the support rod, a moving ring is sleeved in the middle of the outer surface of the support rod, connecting rods are fixedly installed on both sides of the lower end surface of the moving ring, the front end surface and the rear end surface of the moving ring are arranged with through holes, a limiting rod is arranged on the inner side of the through hole, a spring is sleeved on the outer surface of the limiting rod, a connecting ring is sleeved below the outer surface of the support rod, a fixing ring is fixedly connected to the lower end surface of the support rod, a plurality of elastic guide plates are evenly installed on the lower end surface of the fixing ring, and a limiting ring is sleeved below the outer surface of the elastic guide plate.

[0007] Preferably, circular holes are provided on both sides of the upper end surface of the capacitor, the support rod passes through the circular holes, an electrolyte tank is provided below the circular holes, and the circular hole is connected to the electrolyte tank via a connecting groove.

[0008] Preferably, the outer surface of the fixing ring is fixedly connected to the bottom of the connecting groove by welding, and the limiting ring and the elastic guide sheet are both located inside the electrolyte tank.

[0009] Preferably, a limiting plate is sleeved on the outer surface of the limiting rod, one end of the spring is fixedly connected to the outer surface of the limiting plate, the other end of the spring is fixedly connected to the inner wall of the through hole, and the limiting rod is adapted to the limiting hole.

[0010] Preferably, the lower end surface of the connecting rod is fixedly connected to the upper end surface of the limiting ring, and through grooves A are provided on both sides of the upper end surface of the fixing ring, and the connecting rod moves inside the through grooves A.

[0011] Preferably, through grooves B are provided on both sides of the upper end surface of the connecting ring, and the through grooves B are fixedly connected to the connecting rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model is provided with a movable ring, a connecting rod, a connecting ring, a fixed ring, a limiting ring, an elastic guide sheet, a limiting rod and a limiting hole. When the support rod and the fixed ring are installed with the capacitor, the two limiting rods are pulled outward at the same time, the limiting rods leave the inner side of the limiting hole, and the limiting of the movable ring is released, so that the movable ring can be moved upward.
