Description

Technical Field

[0001] The utility model relates to the technical field of capacitor guide pins, in particular to a capacitor guide pin with a protective layer. Background Art

[0002] Two conductors close to each other, with a non-conductive insulating medium in between, constitute a capacitor. When a voltage is applied between the two plates of a capacitor, the capacitor will store charge. The capacitance of a capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates; in the application, the capacitor has two guide pins as a signal source, and its guide pin function consists of two parts, namely internal connection and external connection. The guide pin material consists of two parts: aluminum wire and tinned copper-clad steel wire. After welding by arc welding, a part of the aluminum wire is stamped and deformed, and the required shape and size are obtained through a mold. The deformed part is rectangular, and the other part is not stamped and remains cylindrical.

[0003] Among them, the existing patent CN201420590251.5 is a capacitor guide pin. The internal structure of the device adopts a blade-welded shaft through the capacitor guide pin, which greatly enhances the contact area between the guide pin and the capacitor, and adopts a plug block to weld the wire pin to prevent the guide pin from being pulled out of the capacitor; the guide pin is fixed to the circuit board by a fixing cylinder, which facilitates the disassembly and maintenance of the circuit, and solves the technical problem that most capacitor guide pins are relatively simple to manufacture, and the connection between the capacitor and the circuit board is mostly soldered, which makes it difficult to dismantle and reassemble the capacitor. The capacitor guide pins on the market often cannot solve such technical problems, but the guide pin pins are sharp and the guide pin body is relatively fragile. It is easy to bend and break under force and is very easy to be damaged, especially during transportation and storage. It will suffer losses; therefore, it does not meet the existing needs. We propose a capacitor guide pin with a protective layer. Utility Model Content

[0005] To achieve the above object, the utility model provides the following technical solution: a capacitor guide needle with a protective layer, comprising a capacitor body and two guide needles thereon, and also comprising a protective shell buckled on the capacitor body, wherein the protective shell is detachably connected to the capacitor body, characterized in that: the protective shell comprises a first shell and a second shell, and the interior of the second shell has a cavity for accommodating the two guide needles and a protective mechanism arranged on the capacitor body, the first shell is provided with a mounting mechanism, and the interior of the mounting mechanism is provided with a rotating shaft mechanism;

[0006] The mounting mechanism includes a circular slot opened on the first shell, a first spring fixedly connected to the center of the inner wall surface of one end of the circular slot, a circular slide fixedly connected to one end of the first spring, the circular slide is slidably connected to the circular slot, a tooth groove is opened on the side surface of one end of the circular slot, two first slide grooves are opened on the side surface of the end of the circular slot away from the first spring, a second slide groove is opened on the side surface of the two first slide grooves, blocks are slidably connected inside the two first slide grooves, a second spring is fixedly connected to the inner end surface of the two first slide grooves, the side surfaces of the two blocks are fixedly connected to the limiting slider, and the end surface of the two blocks away from the second spring is set as an inclined surface A.

[0007] Preferably, the rotating shaft mechanism includes a rack fixedly connected to the side surface of one end of the capacitor body, the side surface of the capacitor body is provided with two side slide grooves, one side end of the two side slide grooves is set as a slope B, and a miniature turntable bearing is fixedly connected to the one end surface of the capacitor body.

[0008] Preferably, one end of each of the two second springs is disposed in contact with the surface of the corresponding block, and each of the two limit sliding blocks is slidably connected with the corresponding second sliding groove.

[0009] Preferably, the rack is meshed with the tooth groove correspondingly, the two clamping blocks are slidably connected with the side sliding groove, and the miniature turntable bearing is arranged in contact with the circular slide plate.

[0010] Preferably, the protective shell is made of elastic rubber material, the top inner wall of the cavity is provided with a connecting internal thread, the side wall of the bottom end of the first shell is provided with a connecting external thread, the shape and specification of the connecting external thread are adapted to the connecting internal thread, and the protective shell is tightly closed by using a threaded connection through the cooperation of the connecting external thread and the connecting internal thread.

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

[0013] 1. The utility model aligns the two side grooves on the surface of the capacitor body with the two blocks, and then inserts them into the circular slot. The capacitor body contacts the inclined surface A, and applies pressure to the block until the block is pressed back into the first groove. When the miniature turntable bearing contacts the circular slide plate and pushes the circular slide plate to compress the first spring, the rack is just engaged with the tooth groove, and the block is stuck in the side groove. The first spring presses against the capacitor body to clamp. The rack and the tooth groove are used to facilitate the rotation when the capacitor body is installed.

Finally, by turning the knob between the first shell and the second shell, the connecting external thread on the first shell and the connecting internal thread on the second shell are screwed to lock the protective shells, further improving the connection tightness between the protective shells, and the connection is more stable and not easy to loosen.

[0014] 2. When the utility model needs to be disassembled, the capacitor body is pressed inward, and the capacitor body continues to compress the first spring. When the rack is disengaged from the tooth groove, the action of the inclined surface A and the inclined surface B causes the block to retract again, so that the capacitor body is rotated by degrees. The block and the side slide groove are misaligned to take out the capacitor body. The protective shell and the capacitor body are detachably connected, which is also convenient for easily removing the protective shell when using the capacitor;

[0015] 3. The utility model provides cooperation between the first retaining ring, the second retaining ring and the rubber column, so that when the capacitor falls to the bottom, the guide pin is protected to prevent the guide pin from bending and being damaged when it falls to the bottom. At the same time, when the rubber column falls to the ground, it reduces shock to the capacitor, thereby protecting the capacitor. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The rotating shaft mechanism 6 includes a rack 63 fixedly connected to the side surface of one end of the capacitor body 2. Two side slide grooves 62 are provided on the side surface of the capacitor body 2. One side end of the two side slide grooves 62 is set as an inclined surface B621. A miniature turntable bearing 61 is fixedly connected to the side surface of one end of the capacitor body 2.

[0024] One end of the two second springs 77 is in contact with the surface of the corresponding block 78, and the two limit sliders 79 are slidably connected with the corresponding second slide groove 76. The rack 63 is meshed with the tooth groove 74, the two blocks 78 are slidably connected with the side slide groove 62, and the miniature turntable bearing 61 is in contact with the circular slide plate 73.

[0028] When disassembly is required, press the capacitor body 2 inward, and the capacitor body 2 continues to compress the first spring 72. When the rack 63 disengages from the tooth groove 76, the action of the inclined surface A781 and the inclined surface B621 causes the block 78 to retract again, so that the capacitor body 2 rotates 90°. The block 78 and the side slide groove 62 are misaligned to take out the capacitor body 2. The protective shell 1 and the capacitor body 2 are detachably connected, which also makes it easy to remove the protective shell 1 when using the capacitor.
