Abstract
Description
Technical Field
[0001] This utility model belongs to the field of circuit breaker technology, and in particular relates to a semi-conductive shielding grounding layer for a circuit breaker pole. Background Technology
[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and close, carry, and interrupt current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their application range. The boundary between high and low voltage is relatively blurred. Generally, those above 3kV are called high-voltage electrical appliances. The semi-conductive shielding grounding layer is an important component on the circuit breaker pole.
[0003] The semi-conductive shielding grounding layer is set on the inner wall of the circuit breaker pole and an insulating layer needs to be attached to its outside. However, the existing circuit breaker poles do not have an auxiliary limiting structure on the semi-conductive shielding grounding layer, which makes the insulating layer very easy to shift during injection, thus directly affecting the overall performance of the circuit breaker pole. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a semi-conductive shielding grounding layer for a circuit breaker pole, which solves the problem that the existing circuit breaker pole's semi-conductive shielding grounding layer does not have an auxiliary limiting structure, causing the insulation layer to easily shift during injection, thus directly affecting the overall performance of the circuit breaker pole.
[0005] This utility model is implemented as follows: a semi-conductive shielding grounding layer for a circuit breaker pole includes a semi-conductive shielding grounding layer body disposed within the circuit breaker pole, and an insulating layer disposed on the outer wall of the semi-conductive shielding grounding layer body and located within the circuit breaker pole. Multiple sets of limiting holes are uniformly formed on the outer wall of the semi-conductive shielding grounding layer body and within the circuit breaker pole. Multiple sets of limiting seats that cooperate with the limiting holes are uniformly fixed on the inner walls of the semi-conductive shielding grounding layer body and the insulating layer. Multiple sets of insertion blocks are uniformly fixed at one end of each set of limiting seats. Multiple sets of insertion holes for the insertion blocks to engage are uniformly formed within each set of limiting holes.
[0006] In a preferred embodiment of this invention, the thickness of the insulating layer is greater than the thickness of the semi-conductive shielding grounding layer body.
[0007] As a preferred embodiment of this utility model, one end of each set of limiting seats is a semi-circular structure, and the other end of each set of limiting seats is a cylindrical structure.
[0008] In a preferred embodiment of this invention, the thickness of the semi-conductive shielding grounding layer body is greater than the depth of the limiting hole.
[0009] As a preferred embodiment of this invention, each set of inserts has a semi-circular structure.
[0010] As a preferred embodiment of this invention, the number of insert blocks on each set of limiting seats is at least five.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This invention, by setting a limiting seat and a plug, and cooperating with a limiting hole and a plug hole, can improve the tightness between the semi-conductive shielding grounding layer body and the inner wall of the circuit breaker pole when injecting the insulating layer. At the same time, during the injection of the insulating layer, the locking of the limiting seat and the limiting hole, and the locking of the plug and the plug hole, can be used to improve the tightness between the insulating layer and the semi-conductive shielding grounding layer body, so that the semi-conductive shielding grounding layer body and the insulating layer can fit tightly together. At this time, the use of a double auxiliary limiting method can effectively prevent the insulating layer from easily shifting during injection, thereby avoiding affecting the overall performance of the circuit breaker pole.

[0018] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0019] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0020] like Figures 1 to 3As shown in the figure, the present invention provides a semi-conductive shielding grounding layer for a circuit breaker pole, including a semi-conductive shielding grounding layer body 1 disposed in the circuit breaker pole, and an insulating layer 2 disposed on the outer wall of the semi-conductive shielding grounding layer body 1 and located in the circuit breaker pole. Multiple sets of limiting holes 5 are uniformly opened on the outer wall of the semi-conductive shielding grounding layer body 1 and inside the circuit breaker pole. Multiple sets of limiting seats 3 that cooperate with the limiting holes 5 are uniformly fixed on the inner walls of the semi-conductive shielding grounding layer body 1 and the insulating layer 2. Multiple sets of insert blocks 4 are uniformly fixed at one end of each set of limiting seats 3. Multiple sets of insertion holes 6 for the insert blocks 4 to be engaged are uniformly opened in each set of limiting holes 5. The design of the limiting seats 3, insert blocks 4, limiting holes 5, and insertion holes 6, employing a double auxiliary limiting method, can effectively prevent the insulating layer 2 from easily shifting during injection, thereby avoiding affecting the overall performance of the circuit breaker pole.
[0021] As a preferred embodiment of this invention, the thickness of the insulating layer 2 is greater than the thickness of the semi-conductive shielding grounding layer body 1, which improves the overall insulation effect of the circuit breaker pole and can effectively protect the semi-conductive shielding grounding layer body 1.
[0022] As a preferred embodiment of this utility model, one end of each set of limiting seats 3 is a semi-circular structure, and the other end of each set of limiting seats 3 is a cylindrical structure, which improves the embedding stability.
[0023] As a preferred embodiment of this invention, the thickness of the semi-conductive shielding grounding layer body 1 is greater than the depth of the limiting hole 5, so as to avoid the design of the limiting hole 5 from affecting the overall performance of the semi-conductive shielding grounding layer body 1.
[0024] As a preferred embodiment of this utility model, each set of inserts 4 has a semi-circular structure to facilitate later engagement and further increase the stability of the limiting seat 3 and the limiting hole 5 when they are engaged.
[0025] As a preferred embodiment of this utility model, the number of insert blocks 4 on each set of limiting seats 3 is at least five, which improves the stability between the limiting seats 3 and the limiting holes 5 and prevents easy detachment.
[0026] The working principle of this utility model:
[0027] refer to Figures 1 to 3When the insulation layer 2 is injection-molded, the limiting seat 3 on the semi-conductive shielding grounding layer body 1 is embedded in the limiting hole 5 on the circuit breaker pole, and the corresponding plug 4 is simultaneously embedded in the plug hole 6. This allows the semi-conductive shielding grounding layer body 1 to be quickly attached to the circuit breaker pole, thus initially limiting the semi-conductive shielding grounding layer body 1 and improving its overall stability. Subsequently, the user injection-moldes the insulation layer 2. At this time, the engagement of the limiting seat 3 and the limiting hole 5, and the engagement of the plug 4 and the plug hole 6, directly improves the tightness between the insulation layer 2 and the semi-conductive shielding grounding layer body 1, allowing them to fit tightly together. The use of a dual auxiliary limiting method effectively prevents the insulation layer 2 from shifting during injection, thereby avoiding affecting the overall performance of the circuit breaker pole.
