Description

Technical Field

[0001] The utility model relates to electrical equipment, in particular to an insulating plastic protective cover for terminals, and belongs to the technical field related to electrical equipment. Background Art

[0002] Insulating plastic terminal covers are important electrical accessories, primarily used to protect the wiring terminals of electrical equipment, preventing short circuits, leakage, and other problems caused by external factors. Terminals are components used to connect wires or cables in electrical systems. They are typically made of metal and covered with insulating material to ensure safety and prevent electric shock. The function of terminals is to provide a stable connection point, allowing current to be transmitted from one point to another while ensuring the reliability and safety of the connection.

[0003] The main functions of the insulating plastic protective cover are isolation and protection. It can prevent moisture, dust and other contaminants from contacting the terminals, thereby avoiding potential electric shock hazards and circuit failures. When using the insulating plastic protective cover and the metal terminal, first connect the insulating plastic protective cover to the terminal, then remove the end of the wire with the insulating shell inserted into the insulating protective cover, and then gradually insert one end of the wire into the terminal, and finally use pliers to clamp the end of the exposed conductor of the wire, the terminal and the insulating plastic protective cover so that the three are clamped and pressed together. At this time, the insulating plastic protective cover can protect the terminal, but when the insulating plastic protective cover is pressed by the pliers, the middle part is squeezed together with the terminal, so the end port of the insulating plastic protective cover close to this place will be deformed, and the resulting gap will cause the insulating protective cover to the terminal to be reduced. During use, there is a greater risk that impurities will enter the connection between the terminal and the wire conductor through the gap.

[0004] Therefore, it is urgent to improve the insulating plastic protective sleeve for the terminal to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide an insulating plastic protective cover for terminals, which increases the protection of the connection between the terminal body and the wire by connecting a sealing component and an elastic member to the protective cover body. During the process of inserting the wire into the introduction part, the elastic member ensures the airtightness between one end of the introduction part and the wire. When using pliers to clamp one end of the exposed conductor of the wire and the position of the terminal body and the protective part, the sealing component will not be easily deformed during the pressing process due to its special material, shape and structure, so that there will be no large gap between the protective part and the terminal body, thereby ensuring the sealing, reducing the risk of impurities entering the interior of the protective cover body, and increasing the protection effect.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include: a terminal body connected to the wire conductor, a protective sleeve body, a sealing assembly and an elastic member, the protective sleeve body including an introduction portion and a protective portion connected to and communicated with one end of the introduction portion;

[0007] The sealing assembly is connected to one end of the protection portion away from the introduction portion, and when the terminal body is inserted into the protection portion, the sealing assembly is in close contact with the terminal body;

[0008] The elastic member is connected to one end of the introduction portion away from the protection portion. When the electric wire is inserted into the introduction portion, the elastic member is in close contact with the electric wire.

[0009] Preferably, the sealing assembly includes an elastic annular ring fixedly connected to the inner side wall of the end of the protective part away from the introduction part, and when the terminal body is inserted into the protective part, the elastic annular ring is in close contact with the terminal body.

[0010] Preferably, the sealing assembly includes a soft sealing ring and a connector connected to the sealing ring at one end, the sealing ring and the connector form a U-shape, and the connection between the sealing ring and the connector is elastic, and the end of the connector away from the sealing ring is connected to the port of the protective part, and when the terminal body is inserted into the protective part, the sealing ring is in close contact with the terminal body.

[0011] Preferably, the sealing assembly comprises an elastic arc-shaped ring, and the arc-shaped ring is fixedly connected to the inner side wall of one end of the protective portion away from the introduction portion.

[0027] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] like Figures 1-8 As shown, the insulating plastic protective cover for the terminal provided in this embodiment includes a terminal body 1 connected to the wire conductor, a protective cover body 2, a sealing assembly and an elastic member 3. The protective cover body 2 includes an introduction portion 20 and a protective portion 21 connected to and communicated with one end of the introduction portion 20. The protective portion 21 contacts the terminal body 1, while the introduction portion 20 contacts the wire, and the protective portion 21 is located at the portion where the terminal body 1 is connected to the wire conductor.

[0029] The sealing component is connected to the end of the protective portion 21 away from the introduction portion 20. When the terminal body 1 is inserted into the protective portion 21, the sealing component is in close contact with the terminal body 1. The sealing component ensures that the protective portion 21 will not be easily deformed when squeezed, and forms contact with the terminal body 1, thereby reducing the generation of gaps. The sealing component can be made of rubber or some elastic and soft materials such as polymers;

[0030] The elastic member 3 is connected to the end of the introduction part 20 away from the protective part 21. When the wire is inserted into the introduction part 20, the elastic member 3 is in close contact with the wire. The sealing component provides sealing protection for the protective part 21, while the elastic member 3 ensures the sealing protection of the introduction part 20. When the two ends of the protective cover body 2 are respectively sealed by the sealing component and the elastic member 3, the connection between the terminal body 1 and the wire is better protected.

[0031] Among them, the first embodiment of the elastic member 3 of the present invention is as follows Figure 3 As shown, the sealing assembly includes an elastic annular ring 40 fixedly connected to the inner wall of the end of the protective part 21 away from the introduction part 20. When the terminal body 1 is inserted into the protective part 21, the elastic annular ring 40 will be squeezed, thereby increasing the contact force between the terminal and the protective part 21. When the protective part 21 is squeezed and deformed, the elastic annular ring 40 at the port position of the protective part 21 will reduce the influence of the deformation of the protective part 21 due to its elastic and soft characteristics, thereby increasing the contact effect between the protective part 21 and the terminal body 1, and the elastic annular ring 40 is in close contact with the terminal body 1.

[0032] Furthermore, the second embodiment of the elastic member 3 of the present invention is as follows: Figure 4 as well as Figure 5As shown, the sealing assembly includes a soft sealing ring 41 and a connector 410 connected to the sealing ring 41 at one end. The sealing ring 41 and the connector 410 form a U shape, and the connection between the sealing ring 41 and the connector 410 is elastic. The end of the connector 410 away from the sealing ring 41 is connected to the port of the protective part 21. When the terminal body 1 is inserted into the protective part 21, the sealing ring 41 will come into contact with the terminal body 1. When the protective part 21 is squeezed and deformed, the sealing ring 41 and the connector 410 are connected through the end head, so the influence of the protective part 21 on the sealing ring 41 will be reduced, thereby making the sealing ring 41 in close contact with the terminal body 1.

[0033] Furthermore, the third embodiment of the elastic member 3 of the present invention is as follows: Figure 6 as well as Figure 7 As shown, the sealing assembly includes an elastic arc-shaped ring 42, which is fixedly connected to the inner wall of the end of the protective part 21 away from the introduction part 20. The arc-shaped ring 42 is bulged in the middle and connected to the protective part 21 on both sides. The bulged part of the arc-shaped ring 42 will increase the contact force with the terminal body 1. When the protective part 21 is squeezed and deformed, the sealing assembly in this embodiment will reduce the influence of the protective part 21, so that it will not easily produce a large gap.

[0034] Furthermore, the fourth embodiment of the elastic member 3 of the present invention is as follows: Figure 8 As shown, the sealing assembly includes a soft bracelet ring 43, which is fixedly connected to the end port of the protective part 21 away from the introduction part 20. Because the bracelet ring 43 itself is thicker than the protective part 21, when the protective part 21 is deformed, the protective part 21 has little effect on the bracelet ring 43. Because the bracelet ring 43 is made of elastic soft material, the contact between the bracelet ring 43 and the terminal body 1 will be closer.

[0035] Furthermore, Figure 2 As shown, the elastic member 3 is shaped like a cone extending from the inlet end of the introduction part 20 toward the outlet end of the introduction part 20 and having a gradually decreasing diameter. The elastic member 3 can be composed of some elastic and tensile materials. When one end of the wire is inserted into the introduction part 20, the outer surface of the wire will stretch the elastic member 3, thereby increasing the contact force between the elastic member 3 and the wire, thereby making the protection density between the introduction part 20 and the wire tighter.

[0036] Furthermore, Figure 1 As shown, the outer surface of the protective cover body 2 is provided with anti-slip grooves 5, so that when inserting the terminal body 1 and the wire, the hand will not slip easily when holding the protective cover body 2.

[0037] like Figures 1-8As shown, the principle of the insulating plastic protective cover for the terminal provided in this embodiment is as follows: when in use, first connect the protective cover body 2 with the terminal body 1, and after inserting the protective part 21 at one end of the terminal body 1, insert one end of the wire with the insulating shell removed into the introduction part 20, and then one end of the wire moves toward the protective part 21 through the introduction part 20 and is gradually inserted into the terminal. During the insertion process, under the action of the elastic member 3, the introduction part 20 and the wire will be in close contact, thereby ensuring the airtightness of one end of the introduction part 20. Finally, use pliers to clamp one end of the exposed conductor of the wire, the terminal body 1 and the protective part 21, so that the three are clamped and pressed together. During the pressing process, the sealing component will not be easily deformed due to its special shape and structure, so that there will be no large gap between the protective part 21 and the terminal body 1. The sealing component ensures that one end of the protective part 21 is in close contact with the terminal body 1.

[0038] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0039] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.
