Description

Technical Field

[0001] This utility model relates to a detachable connector. Background Technology

[0002] When using cables to supply power to electrical equipment, electrical connection devices such as terminal blocks are often used, while for high-voltage cables, detachable connectors are required for connection.

[0003] Chinese Patent Publication No. CN 213585123U discloses a temperature-sensing detachable connector, including an insulating sleeve with interconnected transverse and longitudinal mounting cavities. A cable connector is located within the longitudinal mounting cavity. An insulating plug is located at one end of the transverse mounting cavity. A connecting conductor assembly that mates with the cable connector is mounted on the insulating plug. A temperature sensing module is located within the insulating plug. The insulating plug is a truncated cone with one large end facing outwards, and a fixing seat is located at the small end of the truncated cone. The fixing seat has a threaded blind hole. The connecting conductor assembly includes a double-ended stud that passes through the cable connector, with one end of the stud threadedly connected to the threaded blind hole in the fixing seat. This patent directly measures the temperature of the fixing seat, which is fixedly connected to the connecting conductor assembly, through the temperature sensing module. The data is then transmitted to a data acquisition unit via a signal transmitter, effectively solving the shortcomings of traditional temperature measurement products that use indirect methods, resulting in large measurement errors and limited practicality.

[0004] However, in actual use, the aforementioned patented technology suffers from issues. Because the mounting base is made of pure copper, prolonged use can lead to deformation of the threaded blind hole due to thermal expansion and contraction. This deformation results in a loss of reliable connection with the stud. Therefore, improvements are necessary to address this technical problem. Utility Model Content

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] like Figures 1-4 As shown, this utility model discloses a detachable connector, which is an improvement on a temperature-sensing detachable connector disclosed in Chinese Patent Publication No. CN213585123U. The aim is to maintain a reliable connection between the threaded blind hole and the double-ended stud, reducing the impact of thermal expansion and contraction. The structure includes an insulating sleeve 1, within which are interconnected transverse mounting cavities 2 and longitudinal mounting cavities 3. A cable connector 4 is disposed in the longitudinal mounting cavity 3. An insulating plug 5 is disposed at one end of the transverse mounting cavity 2, and a cable socket 16 is inserted at the other end. The insulating plug 5 is a frustum with one large end facing outwards, and a pure copper fixing seat 6 is disposed at the small end of the frustum. A connecting conductor assembly that mates with the cable connector 4 is disposed on the insulating plug 5. The connecting conductor assembly includes a double-ended stud 7 that passes through the cable connector 4. This part of the structure is similar to that disclosed in CN213585123U. The detachable temperature-sensing connector disclosed in 213585123U is similar; the specific improvement of this detachable connector lies in that: a stainless steel bushing 8 is provided inside the fixing base 6, corresponding to the position of the double-ended stud 7. A threaded blind hole 9 is formed inside the stainless steel bushing 8, and one end of the double-ended stud 7 is threadedly connected to the threaded blind hole 9 inside the stainless steel bushing 8. By setting a stainless steel bushing inside a pure copper fixing base, and providing a threaded blind hole inside the stainless steel bushing for connection with the double-ended stud, the stainless steel bushing is less prone to deformation due to thermal expansion and contraction, ensuring a reliable connection between the threaded blind hole and the double-ended stud, thus improving durability.

[0019] In this embodiment, the mounting base 6 is provided with a mounting hole 10, and the stainless steel bushing 8 is fixedly disposed in the mounting hole 10, so that the stainless steel bushing and the mounting base form an integral whole. Specifically, the stainless steel bushing and the mounting base can be fixed by welding.

[0020] In this embodiment, the insulating sleeve 1 is covered with a semi-conductive layer 11 to uniformly insulate the electric field and prevent sudden changes in the electric field at the interface, thereby breaking down the insulation. A rear cap 12 is provided on the outside of the insulating plug 5. The rear cap 12 covers the end of the insulating sleeve 1 where the insulating plug 5 is located. The rear cap 12 is fixedly connected to the semi-conductive layer 11. This part of the structure is the same as a temperature-sensing detachable connector disclosed in CN213585123U. The specific improvement of this detachable connector is that a ring-shaped sealing ring 13 is coaxially provided on the inner side of the rear cap 12. The sealing ring 13 is used to squeeze and seal the gap between the frustum and the transverse mounting cavity to improve the sealing performance.

[0021] Specifically, the sealing ring is made of silicone material.

[0022] Specifically, the inner edge of the sealing ring 13 is provided with an inner annular flange 14 extending and protruding towards the side where the truncated cone is located. The inner annular flange 14 abuts against the end face of the truncated cone away from the cable connector, and the outer surface of the inner annular flange 14 fits against the inner wall of the transverse mounting cavity 2 to improve the sealing effect. Furthermore, in order to facilitate better sealing of the gap between the truncated cone and the transverse mounting cavity, a transition fillet 15 is provided at the transition between the outer surface of the inner annular flange 14 and the sealing ring 13. The transition fillet 15 fits against the fillet of the inner edge of the transverse mounting cavity 2 facing the rear cap 12.

[0023] In another embodiment, the inner wall of the transverse mounting cavity 2 is coated with a hydrophobic nano-coating to prevent condensation in a humid environment.

[0024] It should be noted that this utility model is an improvement upon the temperature-sensing detachable connector disclosed in Chinese Patent Publication No. CN 213585123U. The main improvements include: a stainless steel bushing inside the fixing seat, a sealing ring inside the rear cap, and a hydrophobic nano-coating applied to the inner wall of the transverse mounting cavity. The remaining undisclosed structures and the specific working principle of the detachable connector are the same as those disclosed in Chinese Patent Publication No. CN 213585123U, and will not be repeated here.

[0025] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0026] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0027] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
