Description

Technical Field

[0001] This utility model belongs to the technical field of power transmission and transformation equipment, and specifically relates to a connector protection structure for power supply cables. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables. Cables have many uses, mainly for control installation, connecting equipment, and transmitting power.

[0003] Chinese Patent Application No. 202022008621.8 discloses a power cable connector protection device, including a housing and a heat dissipation assembly. The housing is a cylindrical body open at both ends, comprising a left trapezoidal section, a cylindrical section, and a right trapezoidal section arranged sequentially. The housing is detachably connected by an axially symmetrical upper housing and a lower housing. The power cable passes through the housing, and the power cable connector is located within the cylindrical section of the housing. The heat dissipation assembly includes inner fins and outer fins, each with a plurality of fins. The inner fins are located on the inner wall of the cylindrical section of the housing, and the outer fins are located on the outer wall of the cylindrical section of the housing. This device can improve the heat dissipation efficiency at the power cable connector in the power supply line, provide early warning of abnormal temperature rise at the power cable connector, and control the flame and impact force within the housing in the event of a fire or explosion at the power cable connector, thereby preventing fire accidents caused by power cable connector failure.

[0004] The aforementioned patent features multiple outer fins on the outer wall of the housing. During subsequent use, dust and other impurities from the external environment can fall onto the outer fins, easily affecting their heat dissipation. Furthermore, the multiple outer fins are connected in a ring shape on the outer wall of the housing, and the distance between them is small, making it difficult to clean dust and other impurities from the surface of the outer fins. In addition, directly plugging the two power cables into the two ends of the housing can easily cause friction between the power cables and the inner wall of the housing during plugging and subsequent movement, resulting in wear and tear on the power cables and affecting their subsequent performance. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides a connector protection structure for power cables, which features dust filtering, secure fastening, and fixing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connector protection structure for power supply cables, including a power supply cable connector, both ends of which are connected to power supply cables. An upper housing is provided on one side of the power supply cables and the power supply cable connector, and a lower housing is provided on the other side of the power supply cables and the power supply cable connector. A heat dissipation mechanism is provided on both the upper and lower housings. A clamping component is provided on the inner sidewalls of both ends of the power supply cables and the lower housing. A filter component is provided on the sidewalls of the upper and lower housings, located around the heat dissipation mechanism.

[0007] Preferably, the filter assembly includes a filter cylinder, a mounting component, a first fixing ring, a first end ring, a second fixing ring, and a second end ring. The first fixing ring is connected to one end of the outer side wall of the upper and lower housings, and the second fixing ring is connected to the other end of the outer side wall of the upper and lower housings. The filter cylinder is disposed between the first fixing ring and the second fixing ring. The end of the filter cylinder near the first fixing ring is connected to the first end ring, and the end of the filter cylinder near the second fixing ring is connected to the second end ring. The mounting component is disposed between the second fixing ring and the second end ring, and between the first fixing ring and the first end ring.

[0008] Preferably, the mounting component includes a plug groove, an outer ring, and a clamping ring. A plug groove is provided on the side wall of the first fixing ring at a position corresponding to the first end ring. An outer ring is connected to the outer side wall of the second fixing ring on one side of the second end ring. A clamping ring is connected to the outer side wall of the second fixing ring on the other side of the second end ring.

[0009] Preferably, the second end ring is connected to positioning posts on both sides of the end closest to the outer ring, and positioning holes are provided inside the outer ring at the positions corresponding to the positioning posts.

[0010] Preferably, one end of the clamping ring is provided with a rotating hole, and an anti-slip pad is connected to the inner wall of the rotating hole.

[0011] Preferably, the clamping assembly includes a connecting spring, a fixing sleeve, a mounting plate, a moving rod, and a rubber block. Fixing sleeves are connected to the inner walls of both ends of the upper and lower housings. A moving rod is inserted into the inside of the fixing sleeve. A connecting spring connects the moving rod to the lower housing and the moving rod to the upper housing. A mounting plate is connected to the end of the moving rod away from the fixing sleeve. A rubber block is connected to the side of the mounting plate near the power supply cable.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a filter assembly. The filter screen is sleeved onto the outer periphery of the heat dissipation mechanism components on the upper and lower housings. The first end ring is then inserted into the insertion slot, and the second end ring abuts against the side wall of the outer ring. The clamping ring is then rotated and screwed onto the outer side wall of the second fixing ring, so that it fits against the side wall of the second end ring away from the outer ring, thus realizing the installation operation of the filter screen. Under the action of the filter screen, dust and other impurities in the external environment can be prevented from falling onto the heat dissipation mechanism components, ensuring the heat dissipation effect of the heat dissipation mechanism.

[0014] 2. This utility model is equipped with a clamping component. After the upper and lower housings are fixedly installed around the power supply cable and the power supply cable connector, the rubber block moves under the pressure of the power supply cable. The movement of the rubber block drives the installation plate to move, and the movement of the installation plate drives the moving rod to move inside the fixed sleeve. The movement of the moving rod compresses the connecting spring. Under the action of the rubber blocks set on the inner sidewalls of the upper and lower housings, the two sidewalls of the power supply cable can be clamped and fixed, ensuring the stability of the power supply cable installation, avoiding friction between the power supply cable and the inner sidewalls of the upper and lower housings, thereby avoiding wear on the power supply cable and ensuring the performance of the power supply cable.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-5 The present invention provides the following technical solution: a connector protection structure for a power supply cable, including a power supply cable connector 6, with power supply cables 1 connected to both ends of the power supply cable connector 6, an upper housing 2 provided on one side of the power supply cable 1 and the power supply cable connector 6, and a lower housing 3 provided on the other side of the power supply cable 1 and the power supply cable connector 6, with heat dissipation mechanisms 5 provided on both the upper housing 2 and the lower housing 3, with abutment components 7 provided on the inner sidewalls of both ends of the power supply cable 1 and the lower housing 3, and filter components 4 provided on the sidewalls of the upper housing 2 and the lower housing 3 and located around the heat dissipation mechanisms 5.

[0024] Specifically, the filter assembly 4 includes a filter cylinder 41, a mounting component 42, a first fixing ring 43, a first end ring 44, a second fixing ring 45, and a second end ring 46. The first fixing ring 43 is connected to one end of the outer wall of the upper housing 2 and the lower housing 3, and the second fixing ring 45 is connected to the other end of the outer wall of the upper housing 2 and the lower housing 3. The filter cylinder 41 is positioned between the first fixing ring 43 and the second fixing ring 45. The first end ring 44 is connected to the end of the filter cylinder 41 closest to the first fixing ring 43, and the second end ring 46 is connected to the end of the filter cylinder 41 closest to the second fixing ring 45. The mounting component 42 is positioned between the second fixing ring 45 and the second end ring 46, and between the first fixing ring 43 and the first end ring 44.

[0025] By adopting the above technical solution, after the upper shell 2 and lower shell 3 are fixedly installed on the periphery of the power supply cable 1 and the power supply cable connector 6, the filter screen cylinder 41 is then sleeved onto the periphery of the heat dissipation mechanism 5 on the upper shell 2 and lower shell 3. The first fixing ring 43, the first end ring 44, the second fixing ring 45, and the second end ring 46 are installed and fixed using the mounting part 42, which facilitates the installation and removal of the filter screen cylinder 41. Under the action of the filter screen cylinder 41, dust and other impurities in the external environment can be prevented from falling onto the components of the heat dissipation mechanism 5, thus ensuring the heat dissipation effect of the heat dissipation mechanism 5.

[0026] Specifically, the mounting component 42 includes a insertion groove 421, an outer ring 422, and a clamping ring 423. The insertion groove 421 is provided on the side wall of the first fixing ring 43 at a position corresponding to the first end ring 44. The outer ring 422 is connected to the outer side wall of the second fixing ring 45 on one side of the second end ring 46, and the clamping ring 423 is connected to the outer side wall of the second fixing ring 45 on the other side of the second end ring 46.

[0027] By adopting the above technical solution, after the filter screen cylinder 41 is sleeved onto the periphery of the heat dissipation mechanism 5 on the upper housing 2 and the lower housing 3, the first end ring 44 is inserted into the insertion groove 421, and the second end ring 46 abuts against the side wall of the outer ring 422. Then, the clamping ring 423 is rotated and screwed onto the outer side wall of the second fixing ring 45, and it is made to fit against the side wall of the second end ring 46 away from the outer ring 422. Under the action of the clamping ring 423, the second end ring 46 can be clamped and fixed, thereby ensuring the installation operation of the filter screen cylinder 41.

[0028] Specifically, the second end ring 46 has positioning pins connected to both sides of the end closest to the outer ring 422, and positioning holes are provided inside the outer ring 422 at the positions corresponding to the positioning pins.

[0029] By adopting the above technical solution, after the second end ring 46 abuts against the side wall of the outer ring 422, the positioning pin is then inserted into the positioning hole. With the cooperation of the positioning pin and the positioning hole, the second end ring 46 and the outer ring 422 can be initially positioned to ensure the stability of the abutment between the second end ring 46 and the outer ring 422.

[0030] Specifically, one end of the clamping ring 423 is provided with a rotating hole, and an anti-slip pad is connected to the inner wall of the rotating hole.

[0031] By adopting the above technical solution, when the clamping ring 423 needs to be rotated and screwed onto the outer wall of the second fixing ring 45, the operator's fingers are inserted into the rotating hole, and then force is applied to drive the clamping ring 423 to rotate, which is convenient for the operator to operate. In addition, during the application of force, the anti-slip pad can prevent the operator's hands from slipping.

[0032] In this embodiment, the ends of the two power cables 1 are connected using the power cable connector 6. After the upper housing 2 and the lower housing 3 are fixedly installed around the power cables 1 and the power cable connector 6, the cooperation of the upper housing 2 and the lower housing 3 can provide protection for the power cable connector 6. The heat dissipation mechanism 5 can transfer the heat on the power cable connector 6 to the periphery of the upper housing 2 and the lower housing 3. Then, the filter cylinder 41 is fitted onto the periphery of the heat dissipation mechanism 5 on the upper housing 2 and the lower housing 3. The first end ring 44 is inserted into the insertion slot 421, and the second end ring 46 abuts against the side wall of the outer ring 422. Then, the clamping ring 423 is rotated and screwed onto the outer side wall of the second fixing ring 45, and it is made to fit against the side wall of the second end ring 46 away from the outer ring 422, thus realizing the installation operation of the filter cylinder 41. Under the action of the filter cylinder 41, dust and other impurities in the external environment can be prevented from falling onto the components of the heat dissipation mechanism 5, ensuring the heat dissipation effect of the heat dissipation mechanism 5.

[0033] Example 2

[0034] The difference between this embodiment and Embodiment 1 is that the clamping assembly 7 includes a connecting spring 71, a fixing sleeve 72, a mounting plate 73, a moving rod 74, and a rubber block 75. Fixing sleeves 72 are connected to the inner walls of both ends of the upper housing 2 and the lower housing 3. A moving rod 74 is inserted into the inside of the fixing sleeve 72. A connecting spring 71 connects the moving rod 74 to the lower housing 3 and to the upper housing 2. The end of the moving rod 74 away from the fixing sleeve 72 is connected to the mounting plate 73. A rubber block 75 is connected to the side of the mounting plate 73 closest to the power supply cable 1.

[0035] In this embodiment, after the upper housing 2 and lower housing 3 are fixedly installed around the power supply cable 1 and the power supply cable connector 6, the rubber block 75 moves under the pressure of the power supply cable 1. The movement of the rubber block 75 drives the mounting plate 73 to move, and the movement of the mounting plate 73 drives the moving rod 74 to move inside the fixed sleeve 72. The movement of the moving rod 74 presses against the connecting spring 71. Under the action of the rubber block 75 set on the inner side wall of the upper housing 2 and lower housing 3, the two side walls of the power supply cable 1 can be pressed and fixed, ensuring the stability of the installation of the power supply cable 1, avoiding friction between the power supply cable 1 and the inner side wall of the upper housing 2 and lower housing 3, thereby avoiding wear of the power supply cable 1 and ensuring the performance of the power supply cable 1.

[0036] The structure and principle of the heat dissipation mechanism 5, composed of inner and outer fins, in this utility model have been disclosed in a power cable connector protection device disclosed in Chinese Patent Application No. 202022008621.8. Its working principle is as follows: the inner fins are disposed on the inner walls of the upper shell 2 and the lower shell 3, and the outer fins are disposed on the outer walls of the upper shell 2 and the lower shell 3. The outer fins are flat, long, plate-shaped fins, and are radially distributed along the circumference of the outer walls of the upper shell 2 and the lower shell 3. The long side is parallel to the central axis of the upper shell 2 and the lower shell 3. The inner fins are flat and long plate-shaped fins. The inner fins are distributed in a focused manner along the circumference of the inner wall of the upper shell 2 and the lower shell 3 towards the central axis of the shell. The long side of the inner fins is parallel to the central axis of the upper shell 2 and the lower shell 3. When in use, when the power supply cable connector 6 heats up due to a fault, the heat can be dissipated to the outside air in time through the inner and outer fins on the upper shell 2 and the lower shell 3, and will not continue to accumulate in the upper shell 2 and the lower shell 3.

[0037] The working principle and usage process of this utility model are as follows: This utility model uses a power cable connector 6 to connect the ends of two power cables 1. After the upper housing 2 and lower housing 3 are fixedly installed around the power cables 1 and the power cable connector 6, the rubber block 75 moves under the pressure of the power cables 1. The movement of the rubber block 75 drives the mounting plate 73 to move, which in turn drives the moving rod 74 to move inside the fixed sleeve 72. The moving rod 74 presses against the connecting spring 71. Under the action of the rubber block 75 set on the inner side wall of the upper housing 2 and lower housing 3, the two side walls of the power cables 1 can be pressed and fixed, ensuring the stability of the installation of the power cables 1 and avoiding friction between the power cables 1 and the inner side walls of the upper housing 2 and lower housing 3, thereby preventing wear of the power cables 1. To ensure the effectiveness of the power supply cable 1, the upper housing 2 and lower housing 3 work together to protect the power supply cable connector 6. The heat dissipation mechanism 5 transfers heat from the power supply cable connector 6 to the periphery of the upper housing 2 and lower housing 3. The filter cylinder 41 is then fitted onto the periphery of the heat dissipation mechanism 5 on the upper housing 2 and lower housing 3. The first end ring 44 is inserted into the insertion slot 421, and the second end ring 46 abuts against the side wall of the outer ring 422. The clamping ring 423 is then rotated and screwed onto the outer side wall of the second fixing ring 45, making it fit against the side wall of the second end ring 46 away from the outer ring 422. This completes the installation of the filter cylinder 41. Under the action of the filter cylinder 41, dust and other impurities from the external environment can be prevented from falling onto the components of the heat dissipation mechanism 5, ensuring the heat dissipation effect of the heat dissipation mechanism 5.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
