DETAILED DESCRIPTION
[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Example
[0022] like Figure 1-4 As shown, the utility model provides a capacitor for preventing pin breakage, comprising a capacitor 1, wherein symmetrical pins 2 are fixed on the top surface of the capacitor 1, and further comprising:
[0023] A protective insulating cap 3, wherein the protective insulating cap 3 is sleeved on the outside of one end of the capacitor 1 connecting pin 2, the protective insulating cap 3 is limited and elastically slides on the top of the capacitor 1, and symmetrical concave conductors 4 are vertically slidably connected on both sides of the middle of the protective insulating cap 3, the bottom of the concave conductor 4 is sleeved on the outside of the pin 2 and is electrically connected to the pin 2, the bottom surface of the concave conductor 4 is welded to the top surface of the capacitor 1, and a contact guide block 5 is fixed at the top of the concave conductor 4 located on the top surface of the protective insulating cap 3, and the contact guide block 5 is electrically connected to the concave conductor 4, and a hook wire fixing plate 6 is limited and slides at the position where the top surface of the protective insulating cap 3 is connected to the contact guide block 5, and the hook wire fixing plate 6 slides on the bottom surface of the contact guide block 5 close to one end of the contact guide block 5.
[0024] The position where the capacitor 1 is connected to the protective insulating cap 3 is fixed with a limiting ring 7 , and the bottom of the protective insulating cap 3 is sleeved and slid on the outside of the limiting ring 7 .
[0025] A limiting slot 10 is provided at the position where the protective insulating cap 3 is connected to the wire hook fixing plate 6, and the wire hook fixing plate 6 is limitedly slid inside the limiting slot 10, and the end of the contact guide block 5 away from the concave conductor 4 extends to the inside of the limiting slot 10 and slides on the top surface of the wire hook fixing plate 6.
[0026] A guide block sliding groove 11 is provided at the position where the hooking wire fixing plate 6 is connected to the contact guide block 5 , and the contact guide block 5 is fitted and slidably inserted into the guide block sliding groove 11 .
[0027] The bottom surface of the concave conductor 4 is provided with a conductive plug hole 15 , which is sleeved on the outside of the pin 2 and electrically connected to the pin 2 .
[0028] In this embodiment, the protective insulating cap 3 slides on the outside of the capacitor 1, and the concave conductor 4 is fixed on the top surface of the capacitor 1. Due to the structure of the concave conductor 4 itself, the top will have a hook-shaped plate hooked on the top surface of the protective insulating cap. When the protective insulating cap 3 slides down, the middle part of the concave conductor 4 will slide on the inside of the protective insulating cap 3, allowing the contact guide block 5 at the end of the concave conductor 4 to protrude from the inside of the protective insulating cap 3, which is convenient for welding the contact guide block 5 and the electrode wire. At the same time, the protective insulating cap 3 can be loosened to store the contact guide block 5 after welding into the protective insulating cap 3, so as to avoid damage to the contact guide block 5 caused by scratches, thereby improving the protective effect of the contact guide block 5 after connection.
[0029] Usage process: If you need to weld pin 2 directly, you can directly fit the wire connecting pin 2 to the contact guide block 5 and use soldering to weld. If higher strength welding is required, you can insert the electrode connecting pin 2 into the wire hole 12 and solder the inside of the wire hole 12 into tin liquid to complete the welding. When you need to separate the welding position, you can press the protective insulating cap 3 to let the contact guide block 5 protrude. At this time, heat both sides of the contact guide block 5 to melt the solder and complete the separation of the electrodes.
[0030] When soldering conditions are not available, the connecting wire electrode can be inserted into the wire hole 12, and the wire can be hooked outward using the wire hook fixing plate 6 to form a winding around the contact guide block 5, thereby completing the high-strength fixation of the wire without welding.
[0031] When the wire is inserted into the wire hole 12 and cannot be hooked out through the wire hook fixing plate 6, the protective insulating cap 3 can be pressed to expose the contact guide block 5, so that the winding of the wire and the contact guide block 5 can be completed quickly. Example
[0032] like Figure 1-4 As shown, based on the first embodiment, a circularly distributed telescopic rod 8 is fixed to the top surface of the limit ring 7, the other end of the telescopic rod 8 is fixed to the inner wall of the protective insulating cap 3, and a reset spring 9 is sleeved on the outside of the telescopic rod 8, and the two ends of the reset spring 9 are respectively in contact with the top surface of the limit ring 7 and the inner wall of the protective insulating cap 3.
[0033] The contact guide block 5 is provided with a wire hole 12 at the center of one end inside the guide block slide groove 11, and the lower part of the wire hole 12 extends to the inner side of the wire hook fixing plate 6. The top surface of the wire hook fixing plate 6 is located at the bottom of the guide block slide groove 11 and is provided with a hook groove 13. One end of the hook groove 13 is connected with the wire hole 12 on the bottom surface of the contact guide block 5, and the other end of the hook groove 13 is provided with a card groove 14, and the side surface of the card groove 14 is connected with the guide block slide groove 11.
[0034] In this embodiment, the telescopic rod 8 can reinforce the connection of the protective insulating cap 3 and enhance the connection strength between the protective insulating cap 3 and the capacitor 1, while the reset spring 9 can push the protective insulating cap 3 to reset upward to fix the connected electrode wire.
[0035] When the contact guide block 5 is connected to the external electrode wire, the wire hole 12 can be passed through the wire hole 12 to increase the strength of welding. At the same time, when welding conditions are not available, the wire can be passed through the wire hole 12 to the bottom of the wire hook fixing plate 6, and the wire passed through the wire hole 12 can be pulled from the bottom of the wire hole 12 to the lower outside of the contact guide block 5 by pulling the wire hook fixing plate 6. The wire passed through the wire hole 12 is hooked by the wire hook fixing plate 6 to form a hook shape. The hooked wire is taken out from the hook groove 13 and twisted together with the wire located on the upper part of the contact guide block 5. The wire can be wound around the outside of the contact guide block 5 to ensure the stability of the electrode wire connection.
[0036] When the wire winding is completed, the wire hooking and fixing plate 6 is pushed, and the wire wound outside the contact guide block 5 can be clamped and fixed by using the groove and the clamping groove 14 .
[0037] It should be noted that when the wire is inserted into the wire hole 12, since the wire hole 12 is opened in the wire hook fixing plate 6, the wire can be pulled outward by pulling the wire hook fixing plate 6, so that the wire forms a hook shape, thereby facilitating the removal of the end of the wire.
[0038] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
