Description

Technical Field

[0001] This utility model relates to the field of microcapacitor protection technology, and more specifically, to a protective device for microcapacitors to prevent damage. Background Technology

[0002] A microcapacitor typically refers to a capacitor used to fine-tune the capacitance value in a circuit; it is also called a trimmer capacitor. A trimmer capacitor consists of two parallel-plate-like electrodes sandwiched in an insulating material. By rotating the external structure of the trimmer capacitor, the distance between the two electrode plates can be changed, thus affecting the capacitance value.

[0003] Since microcapacitors lack protective structures on their outer surfaces, especially their leads, collisions between microcapacitors during transportation and other external factors can easily cause the leads to bend and break, affecting the normal use of the microcapacitors. Furthermore, microcapacitors are also easily damaged by compression. Therefore, we propose a protective device to prevent damage to microcapacitors and solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a protective device for microcapacitors to prevent damage. It can not only effectively prevent the microcapacitor body from being squeezed and damaged during transportation, but also prevent the terminals from being bent and falling off, thus providing a good protective effect for the microcapacitor body.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A protective device for preventing damage to a microcapacitor includes a microcapacitor body and a terminal block installed on the microcapacitor body. The bottom of the microcapacitor body is detachably connected to a base, and the base has a placement groove that forms an embedded structure with the bottom of the microcapacitor body.

[0009] A ring is installed on the outer side of the base, and the inner wall of the ring is provided with internal threads;

[0010] A protective cover is detachably connected to the outside of the microcapacitor body, and the inner diameter of the bottom end of the protective cover is adapted to the outer diameter of the microcapacitor body. An external thread is provided at the root of the outer wall of the protective cover to be screwed into the internal thread. A protective sleeve is fixedly connected to the top of the protective cover and sleeved on the outside of the terminal block, and the inner diameter of the protective sleeve is larger than the outer diameter of the terminal block.

[0011] Furthermore, the top and bottom edges of the base are both fixedly connected with a first limiting flange, and the outer diameter of the first limiting flange is adapted to the inner diameter of the ring.

[0012] Furthermore, the bottom opening of the ring is integrally formed with a second limiting flange, and the inner diameter of the second limiting flange is adapted to the outer diameter of the base.

[0013] Furthermore, the outer wall of the ring is fixedly connected with anti-slip protrusions, and multiple anti-slip protrusions are provided at the radial position of the ring.

[0014] Furthermore, a boss is electrically connected between the protective sleeve and the protective cover, and the outer diameter of the boss is larger than the outer diameter of the protective sleeve.

[0015] Furthermore, a reinforcing rib is fixedly connected to the part where the root of the protective sleeve meets the boss, and multiple reinforcing ribs are provided in the radial position of the protective sleeve.

[0016] Furthermore, the base, ring, and protective sleeve are all made of hard plastic.

[0017] 3. Beneficial effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] (1) In this solution, the microcapacitor body is placed on the base and the bottom end of the microcapacitor body is embedded into the inner side of the placement groove. Then, the protective cover is placed on the outside of the microcapacitor body and the protective cover is placed on the outside of the terminal block. By matching the inner diameter of the base of the protective cover with the outer diameter of the microcapacitor body, and by making the bottom end of the protective cover fit against the upper surface of the base, the ring is rotated relative to the base to make the internal thread and the external thread screwed together to lock the protective cover, thereby protecting the entire microcapacitor body. This not only effectively prevents the microcapacitor body from being squeezed and damaged during transportation, but also prevents the terminal block from bending and falling off, thus providing a good protective effect for the microcapacitor body.

[0020] (2) This solution can enhance the strength, rigidity and torsional resistance of the protective sleeve by setting reinforcing ribs, which can overcome the product distortion caused by uneven stress due to the difference in wall thickness of the protective sleeve, so as to increase the strength of the joint surface with the boss and ensure the protective effect of the protective sleeve.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please see Figure 1-5 A microcapacitor protection device for preventing damage includes a microcapacitor body 1 and a terminal block 2 installed on the microcapacitor body 1. A base 3 is detachably connected to the bottom of the microcapacitor body 1. A placement groove 4 is provided on the base 3 to form an embedded structure with the bottom of the microcapacitor body 1.

[0031] A ring 6 is installed on the outer side of the base 3, and the inner wall of the ring 6 is provided with an internal thread 7;

[0032] A protective cover 10 is detachably connected to the outside of the microcapacitor body 1, and the inner diameter of the bottom end of the protective cover 10 is adapted to the outer diameter of the microcapacitor body 1. An external thread 11 is provided at the root of the outer wall of the protective cover 10 and is screwed into the internal thread 7. A protective sleeve 12 is fixedly connected to the top of the protective cover 10 and is sleeved on the outside of the terminal 2, and the inner diameter of the protective sleeve 12 is larger than the outer diameter of the terminal 2.

[0033] It should be noted that when using this microcapacitor damage prevention protection device, firstly, the microcapacitor body 1 is placed on the base 3, and the bottom end of the microcapacitor body 1 is embedded into the inner side of the placement groove 4. Then, the protective cover 10 is placed on the outside of the microcapacitor body 1, and the protective sleeve 12 is placed on the outside of the terminal 2. By matching the inner diameter of the base of the protective sleeve 12 with the outer diameter of the microcapacitor body 1, and by making the bottom end of the protective sleeve 12 fit against the upper surface of the base 3, the ring 6 is rotated relative to the base 3, so that the internal thread 7 and the external thread 11 are screwed together, locking the protective cover 10, thereby protecting the entire microcapacitor body 1. This not only effectively prevents the microcapacitor body 1 from being squeezed and damaged during transportation, but also prevents the terminal 2 from bending and falling off, providing excellent protection for the microcapacitor body 1.

[0034] like Figure 1 , Figure 2 As shown, the top and bottom edges of the base 3 are both fixedly connected with a first limiting flange 5, and the outer diameter of the first limiting flange 5 is adapted to the inner diameter of the ring 6. The bottom edge of the ring 6 is integrally formed with a second limiting flange 8, and the inner diameter of the second limiting flange 8 is adapted to the outer diameter of the base 3.

[0035] It should be noted that by having the second limiting flange 8 fit against the first limiting flange 5, the ring sleeve 6 can be effectively prevented from detaching from the base 3.

[0036] like Figure 4 As shown, the outer wall of the ring sleeve 6 is fixedly connected with anti-slip protrusions 9, and multiple anti-slip protrusions 9 are provided in the radial position of the ring sleeve 6;

[0037] It should be noted that by setting anti-slip protrusions 9 on the outer wall of the ring 6, the friction between the hand and the ring 6 can be increased, thus making it easier to manually drive the ring 6 to rotate.

[0038] like Figure 1 As shown, a boss 13 is electrically connected between the protective sleeve 12 and the protective cover 10, and the outer diameter of the boss 13 is larger than the outer diameter of the protective sleeve 12. A reinforcing rib 14 is fixedly connected to the part where the root of the protective sleeve 12 is combined with the boss 13, and multiple reinforcing ribs 14 are provided in the radial position of the protective sleeve 12.

[0039] It should be noted that by setting the reinforcing rib 14, the strength, rigidity and torsional resistance of the protective sleeve 12 can be enhanced, which can overcome the product distortion caused by uneven stress due to the difference in wall thickness of the protective sleeve 12, so as to increase the strength of the joint surface with the boss 13 and ensure the protective effect of the protective sleeve 12.

[0040] The base 3, ring 6, and protective sleeve 12 are all made of hard plastic.

[0041] In use: First, place the microcapacitor body 1 on the base 3 and insert the bottom end of the microcapacitor body 1 into the inner side of the placement groove 4. Then, put the protective cover 10 on the outside of the microcapacitor body 1 and put the protective sleeve 12 on the outside of the terminal 2. When the inner diameter of the base of the protective sleeve 12 matches the outer diameter of the microcapacitor body 1, and the bottom end of the protective sleeve 12 is in contact with the upper surface of the base 3, the ring 6 is rotated relative to the base 3, so that the internal thread 7 and the external thread 11 are screwed together to lock the protective cover 10, thereby protecting the entire microcapacitor body 1.

[0042] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
