Description

Technical Field

[0001] The present invention relates to the technical field of cable connection devices, and specifically to a power cable connection device. Background Art

[0002] A cable is a rope-like conductive device formed by stranding several or several groups of wires. When a cable breaks, it is usually necessary to use a connector to assist in the connection. A connector generally connects two groups of cables so that the two groups of cables are electrically connected through the connector.

[0003] Currently, cable connectors generally used for connecting cables with voltages above 10 kV are in the shape of a circular tube. By sleeving the metal parts of the two groups of cables on the inner walls at both ends of the metal circular tube respectively, and through pressing the circular tube or connecting the circular tube with bolts by threads, the circular tube and the cable are abutted against each other, thereby realizing electrical connection;

[0004] This method of connection is simple, but when the cable is subjected to tensile force or shakes, the abutted part between the circular tube and the cable will shake, resulting in the separation of the circular tube and the cable;

[0005] On the other hand, for a cable connector that connects the circular tube and the cable by pressing the circular tube, it cannot be used repeatedly. For example, if the abutted area between the circular tube and the cable is less than the standard value during the installation process, only the connection part of the cable and the circular tube can be cut off, and a new cable connector is used for connection again. And after the installation is completed, the function of quick disassembly cannot be achieved;

[0006] For the method of connecting the circular tube and the cable by connecting the circular tube with bolts by threads and using the bolts to abut the circular tube and the cable, although the adjustment during the installation process can be achieved, the abutted area between the bolts and the cable is small, and it is not suitable for connecting cables with voltages above 10 kV.

[0011] As a preferred technical solution of the present invention: the cable connector also includes an abutment block arranged between the horn sleeve one and the horn sleeve two, limit blocks are arranged on both sides of the abutment block, and the side of the limit block away from the abutment block is fixedly assembled with an inlaid block, and the outer edges of the horn sleeve one and the horn sleeve two are sleeved with a clamping ring.

[0012] As a preferred technical solution of the present invention: the clamping seat and the inner wall of the clamping groove are sleeved, the inlay plate and the inner wall of the inlay groove are sleeved, the sealing ring is arranged between the speaker sleeve one and the speaker sleeve two, and the speaker sleeve one and the speaker sleeve two are fixed by a clamping ring sleeve.

[0013] As a preferred technical solution of the present invention: the connector installation device includes a base plate, and the top of both sides of the base plate are fixedly equipped with a telescopic rod 1, the top of the base plate is fixedly equipped with a slide rail, the outer wall of the slide rail is slidably sleeved with two groups of clamping frames, the inner wall of the clamping frame is provided with a clamping groove 2, the inner wall of the clamping groove 2 is fixedly equipped with a telescopic rod 2, the telescopic end of the telescopic rod 2 is fixedly equipped with a clamping plate, the clamping frame is provided with a clamping groove on the side away from the clamping groove 2, the top of the clamping groove is provided with a through groove, and the top of the base plate is fixedly equipped with a telescopic rod 3.

[0014] As a preferred technical solution of the present invention: the telescopic ends of the telescopic rod 1 located on both sides of the bottom plate are respectively fixedly assembled with two groups of clamping frames, the clamping groove 2 is arc-shaped close to the side of the clamping groove, the telescopic rod 3 is arranged between the two groups of clamping frames, and the telescopic rod 3 is close to the outer wall of one group of clamping frames, and the outer wall of one group of clamping frames away from the end of the clamping groove is provided with a storage groove, and the auxiliary mounting structure is clamped to the inner wall of the storage groove.

[0015] As a preferred technical solution of the present invention: the outer edges of the opposite ends of the two groups of the card slots are provided with abutment chamfers, and the top telescopic end of the telescopic rod three is fixedly equipped with a cutting blade.

[0016] As a preferred technical solution of the present invention: the auxiliary installation structure includes a socket, the outer wall of the socket is fixedly equipped with a limit plate, the outer wall of the limit plate is fixedly equipped with a clamping groove three, and the inner wall of the clamping groove three is clamped with a cone.

[0017] The present invention has the following beneficial effects:

[0018] For this power cable connection device, the end of the battery cell expands through the limiting block and the inlay block, so that the shape of the end of the battery cell is adapted to the inner wall of the first horn sleeve. Since the limiting block and the inlay block keep abutting against the battery cell, the expanded part of the battery cell will not shrink. Therefore, a lock can be formed between the expanded part of the battery cell and the inner wall of the first horn sleeve;

[0019] Dock the first horn sleeve and the second horn sleeve so that the clamping seat is located on the inner wall of the first clamping groove. By clamping the inlay plate on the inner wall of the clamping seat, the clamping seat expands at the end close to the first horn sleeve. Utilize the end of the clamping seat close to the first horn sleeve to expand through the inlay plate to realize the locking between the second horn sleeve and the first horn sleeve, so that the two cable bodies are connected through the cable connector;

[0020] It solves the problem that the traditional cable connection device cannot be used multiple times. For example, in the installation process, if the abutting area between the round tube and the cable is less than the standard value, only the connection part of the cable and the round tube can be cut off and a new cable connector can be used for connection again. And after the installation is completed, it cannot be quickly disassembled;

[0021] Since the two cable bodies are abutted by the abutting block, the relative distance between the two battery cells increases. Therefore, after the first horn sleeve and the second horn sleeve are docked and fixed through the clamping seat and the inlay plate, the abutting force of the two cable bodies by the abutting block can force the clamping seat and the first clamping groove to move away from each other. And utilize the inlay plate to expand the inlay groove, so that the expanded part of the inlay groove driving the clamping seat can clamp the first clamping groove, thereby realizing the firmness between the first horn sleeve and the second horn sleeve. At the same time, since the limiting block and the inlay block keep abutting against the battery cell, the expanded part of the battery cell will not shrink;

[0022] It solves the problem that in the traditional cable connection device, when the cable is subjected to tensile force or shakes, the abutting part between the round tube and the cable will shake, resulting in the separation of the round tube and the cable;

[0023] By abutting the two battery cells with the abutting block, when the two cable bodies transmit power through the cable connector, if the heat generation between the two cable bodies and the cable connector is large, its heat source can melt the abutting block and the inlay block, so that the liquid abutting block and inlay block can weld between the battery cell, the first horn sleeve and the second horn sleeve, thereby increasing the connection stability between the cable body and the cable connector;

[0024] It solves the problem that the abutting area between the bolt and the cable in the traditional cable connection device is small and it is not applicable to the cable connection with a voltage above KV. Brief Description of the Drawings

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figure 1 - Figure 10 , a power cable connection device, including a cable main body 2, and a cable connector 1 fixedly sleeved at the end of the cable main body 2;

[0042] And a connector installation device 3 for installing the cable connector 1, and an auxiliary installation structure 4 for assisting in installing the cable connector 1 is clamped on the inner wall of the connector installation device 3.

[0043] In a preferred implementation mode: the cable connector 1 includes a horn sleeve one 101 and a horn sleeve two 103. A clamping groove one 102 is opened on the outer wall of the horn sleeve one 101 close to the horn sleeve two 103. A clamping seat 104 is fixedly assembled on the outer wall of the horn sleeve two 103 close to the horn sleeve one 101. An inlay groove 105 is opened at the end of the clamping seat 104 close to the horn sleeve one 101. A limiting tube 106 is sleeved on the outer wall of the horn sleeve one 101. An inlay plate 107 is fixedly assembled on the outer wall of the limiting tube 106. A sealing ring 108 is arranged between the horn sleeve one 101 and the horn sleeve two 103. A pulling groove 109 is opened at the end of the sealing ring 108.

[0044] In a preferred implementation mode: the cable connector 1 further includes an abutting block 110 arranged between the horn sleeve one 101 and the horn sleeve two 103. Limiting blocks 111 are arranged on both sides of the abutting block 110. Inlay blocks 112 are fixedly assembled on the sides of the limiting blocks 111 away from the abutting block 110. A clamping ring 113 is sleeved on the outer edges of the horn sleeve one 101 and the horn sleeve two 103.

[0045] In a preferred implementation mode: the inner wall of the clamping seat 104 and the clamping groove one 102 are sleeved, the inner wall of the inlay plate 107 and the inlay groove 105 are sleeved, the sealing ring 108 is arranged between the horn sleeve one 101 and the horn sleeve two 103, and the horn sleeve one 101 and the horn sleeve two 103 are fixedly sleeved through the clamping ring 113.

[0046] In the above structure, by stripping part of the outer skin 201 of the cable, the battery cell 202 is exposed. The battery cell 202 is placed on the inner wall of the first horn sleeve 101, with the horn mouth of the first horn sleeve 101 facing the outside of the battery cell 202. By inlaying the limiting block 111 and the inlaying block 112 into the end of the battery cell 202, an inlay cavity 203 is formed, so that the end of the battery cell 202 expands through the limiting block 111 and the inlaying block 112, and then the shape of the end of the battery cell 202 is adapted to the inner wall of the first horn sleeve 101. Since the limiting block 111 and the inlaying block 112 keep abutting against the battery cell 202, the expanded part of the battery cell 202 will not shrink. Therefore, a lock can be formed between the expanded part of the battery cell 202 and the inner wall of the first horn sleeve 101;

[0047] Another group of cable bodies 2 are fixedly sleeved with the second horn sleeve 103 by the above method;

[0048] Then, the first horn sleeve 101 and the second horn sleeve 103 are butted, so that the clamping seat 104 is located on the inner wall of the first clamping groove 102. By clamping the inlay plate 107 on the inner wall of the clamping seat 104, the clamping seat 104 expands at the end close to the first horn sleeve 101. By using the end of the clamping seat 104 close to the first horn sleeve 101 to expand through the inlay plate 107, the lock between the second horn sleeve 103 and the first horn sleeve 101 is realized, so that the two groups of cable bodies 2 are connected through the cable connector 1;

[0049] By arranging the abutting block 110 between the two groups of limiting blocks 111, the two groups of battery cells 202 abut against the limiting block 111 and the inlaying block 112 by using the abutting block 110, so that the two groups of battery cells 202 abut against each other through the abutting block 110, thus increasing the abutting force between the two groups of battery cells 202 and the inner walls of the first horn sleeve 101 and the second horn sleeve 103;

[0050] At the same time, since the two groups of cable bodies 2 are abutted by the abutting block 110, the relative distance between the two groups of battery cells 202 increases. Therefore, after the first horn sleeve 101 and the second horn sleeve 103 are butted and fixed through the clamping seat 104 and the inlay plate 107, the abutting force of the two groups of cable bodies 2 on the abutting block 110 can force the clamping seat 104 and the first clamping groove 102 to be away from each other. By using the inlay plate 107 to expand the inlay groove 105, the expansion part of the inlay groove 105 driving the clamping seat 104 can clamp the first clamping groove 102, so as to keep the first horn sleeve 101 and the second horn sleeve 103 stable;

[0051] The abutting block 110 and the inlaying block 112 can be prepared from tin, copper, aluminum, iron or steel, and tin is preferred;

[0052] By abutting the two groups of battery cells 202 with the abutting block 110, when the two groups of cable bodies 2 transmit power through the cable connector 1, if the heat generation between the two groups of cable bodies 2 and the cable connector 1 is relatively large, the heat source can melt the abutting block 110 and the inlay block 112, so that the liquid abutting block 110 and inlay block 112 can weld between the battery cell 202, the horn sleeve one 101, and the horn sleeve two 103, thereby increasing the connection stability between the cable body 2 and the cable connector 1.

[0053] On the other hand, the hardness of tin is relatively low. Therefore, when the horn sleeve one 101 and the horn sleeve two 103 are clamped and fixed through the inlay plate 107 and the inlay groove 105, the tin can be deformed to a certain extent under the extrusion of the horn sleeve one 101 and the horn sleeve two 103.

[0054] In a preferred embodiment: The connector installation device 3 includes a bottom plate 301. On both sides of the top of the bottom plate 301, a first telescopic rod 302 is fixedly assembled. On the top of the bottom plate 301, a slide rail 303 is fixedly assembled. Two groups of clamping frames 304 are slidably sleeved on the outer wall of the slide rail 303. A second clamping groove 305 is opened on the inner wall of the clamping frame 304. A second telescopic rod 306 is fixedly assembled on the inner wall of the second clamping groove 305. A clamping plate 307 is fixedly assembled at the telescopic end of the second telescopic rod 306. A clamping groove 308 is opened on one side of the clamping frame 304 away from the second clamping groove 305. A through groove 309 is opened at the top of the clamping groove 308. A third telescopic rod 311 is fixedly assembled on the top of the bottom plate 301.

[0055] In the above structure, through the sliding sleeve connection of the clamping frame 304 and the slide rail 303, and the fixed assembly of the telescopic end of the first telescopic rod 302 and the clamping frame 304, the first telescopic rod 302 can drive the two groups of clamping frames 304 to move relatively;

[0056] By opening the second clamping groove 305 and using the second telescopic rod 306 to drive the clamping plate 307, the cable body 2 can be clamped and sleeved through the clamping plate 307 and the second clamping groove 305. The third telescopic rod 311 is used to drive the cutting blade 312 to rise, so that the cutting blade 312 abuts against the cable outer skin 201. By rotating the connector installation device 3, the third telescopic rod 311 can perform a circular cutting on the cable outer skin 201 through the cutting blade 312. The two groups of clamping frames 304 are used to clamp the cable outer skin 201 through the second telescopic rod 306 and the second clamping groove 305. The first telescopic rod 302 drives the two groups of clamping frames 304 to move in the opposite direction, so that the circularly cut part of the cable outer skin 201 can be separated from the battery cell 202;

[0057] By clamping the auxiliary installation structure 4 to the inner wall of a set of second clamping grooves 305 through the clamping plate 307, sleeving the first horn sleeve 101 on the outer wall of the cable main body 2, driving the two clamping brackets 304 to move relatively through the first telescopic rod 302, enabling the auxiliary installation structure 4 to abut against the center of the battery cell 202, causing the end of the battery cell 202 to expand under the abutment of the auxiliary installation structure 4, and further making the expanded part of the battery cell 202 fit the inner wall of the first horn sleeve 101, then filling the limiting block 111 and the inlay block 112 into the inlay cavity 203 formed by the abutment of the auxiliary installation structure 4 against the battery cell 202, so that the expanded part of the battery cell 202 is held by the limiting block 111 and the inlay block 112;

[0058] Another set of cable main body 2 and the second horn sleeve 103 are prepared in the same way as above;

[0059] Then place the abutting block 110 between the two limiting blocks 111, place the first horn sleeve 101 and the second horn sleeve 103 in the clamping groove 308, drive the two clamping brackets 304 to move relatively through the first telescopic rod 302, enabling the clamping brackets 304 to squeeze the first horn sleeve 101 and the second horn sleeve 103 in the opposite direction through the clamping groove 308. When the inlay groove 105 is located at the outer edge of the first clamping groove 102 close to the first horn sleeve 101, snap the inlay plate 107 to the inner wall of the inlay groove 105, and sleeve the snap ring 113 on the outer walls of the second horn sleeve 103 and the limiting tube 106.

[0060] In a preferred embodiment: the telescopic ends of the first telescopic rods 302 on both sides of the bottom plate 301 are fixedly assembled with the two clamping brackets 304 respectively. The side of the second clamping groove 305 close to the clamping groove 308 is arc-shaped. The third telescopic rod 311 is arranged between the two clamping brackets 304 and is close to the outer wall of one clamping bracket 304. A storage groove 313 is formed on the outer wall of one clamping bracket 304 at the end far from the clamping groove 308, and the auxiliary installation structure 4 is clamped to the inner wall of the storage groove 313.

[0061] In the above structure, due to the side of the second clamping groove 305 close to the clamping groove 308 being arc-shaped, when the cable main body 2 is placed at the second clamping groove 305, the second clamping groove 305 can hold the outer wall of the cable main body 2 with uniform force. By driving the cutting blade 312 through the third telescopic rod 311, the contact thickness between the cutting blade 312 and the cable main body 2 can be controlled by the telescopic stroke of the third telescopic rod 311, so as to be applicable to the peeling of different types of cable outer sheaths 201.

[0062] In a preferred embodiment: abutting chamfers 310 are formed on the outer edges of the opposite ends of the two clamping grooves 308, and a cutting blade 312 is fixedly assembled at the top telescopic end of the third telescopic rod 311.

[0063] In the above structure, abutting chamfers 310 are formed on the outer edges of the opposite ends of the card slot 308. When the first horn sleeve 101 and the second horn sleeve 103 are clamped through the card slot 308, the outer edges of the first horn sleeve 101 and the second horn sleeve 103 can increase the friction force with the card slot 308 through the abutting chamfers 310, thereby avoiding the problem that the first horn sleeve 101 and the second horn sleeve 103 slide out through the through slot 309 during the abutting process.

[0064] In a preferred embodiment: The auxiliary installation structure 4 includes a card seat 401. A limiting plate 402 is fixedly assembled on the outer wall of the card seat 401. A third card slot 403 is fixedly assembled on the outer wall of the limiting plate 402. A cone 404 is clamped on the inner wall of the third card slot 403.

[0065] In the above structure, the cone 404 is clamped on the inner wall of the third card slot 403, so that the cone 404 can be disassembled. Furthermore, the limiting block 111 can be clamped on the inner wall of the third card slot 403, so that the limiting block 111 can be fixedly assembled with the inner wall of the second card slot 305 through the auxiliary installation structure 4, and thus the limiting block 111 and the inlay block 112 can be filled into the inner wall of the inlay cavity 203 through the connector installation device 3.

[0066] Working principle: The clamping frame 304 and the slide rail 303 are slidably sleeved. The telescopic end of the first telescopic rod 302 is fixedly assembled with the clamping frame 304, so that the first telescopic rod 302 can drive the two clamping frames 304 to move relatively.

[0067] By forming the second card slot 305, the second telescopic rod 306 drives the clamping plate 307, so that the cable main body 2 can be clamped and sleeved through the clamping plate 307 and the second card slot 305. The third telescopic rod 311 drives the cutting blade 312 to rise, so that the cutting blade 312 abuts against the cable outer sheath 201. By rotating the connector installation device 3, the third telescopic rod 311 uses the cutting blade 312 to perform a circular cutting on the cable outer sheath 201. The two clamping frames 304 clamp the cable outer sheath 201 through the second telescopic rod 306 and the second card slot 305. The first telescopic rod 302 drives the two clamping frames 304 to move in opposite directions, so that the circularly cut part of the cable outer sheath 201 can be separated from the battery cell 202 through the cutting blade 312.

[0068] By clamping the auxiliary installation structure 4 to the inner wall of a second card slot 305 through the clamping plate 307, sleeving the first horn sleeve 101 on the outer wall of the cable main body 2, and driving the two clamping frames 304 to move relatively by the first telescopic rod 302, the auxiliary installation structure 4 abuts against the center of the battery cell 202, so that the end of the battery cell 202 expands under the abutment of the auxiliary installation structure 4. Furthermore, the expanded part of the battery cell 202 is adapted to the inner wall of the first horn sleeve 101.

[0069] Snap the limit block 111 onto the inner wall of the third clamping groove 403, so that the limit block 111 is fixedly assembled with the inner wall of the second clamping groove 305 through the auxiliary installation structure 4. Drive the two clamping brackets 304 to move relative to each other through the first telescopic rod 302, so that the limit block 111 and the inlay block 112 are filled into the inlay cavity 203 formed by the auxiliary installation structure 4 abutting against the battery cell 202, and the expansion part of the battery cell 202 is held by the limit block 111 and the inlay block 112;

[0070] The other cable body 2 and the second horn sleeve 103 are prepared in the same way as the above method;

[0071] Then place the abutting block 110 between the two limit blocks 111, and place the first horn sleeve 101 and the second horn sleeve 103 in the clamping groove 308. Drive the two clamping brackets 304 to move relative to each other through the first telescopic rod 302, so that the clamping brackets 304 squeeze the first horn sleeve 101 and the second horn sleeve 103 in the opposite direction through the clamping groove 308. When the inlay groove 105 is located at the outer edge of the first clamping groove 102 close to the first horn sleeve 101, snap the inlay plate 107 onto the inner wall of the inlay groove 105, and then fill the sealing ring 108 between the first horn sleeve 101 and the second horn sleeve 103, so that the first horn sleeve 101 and the second horn sleeve 103 are fixedly assembled through the sealing ring 108. Then sleeved the snap ring 113 on the outer walls of the second horn sleeve 103 and the limit tube 106.
