The number of contact surfaces between the first split body and a cable to be connected is two, one contact surface is the inner surface of the containing cavity, the other contact surface is the peripheral surface of the first split body, and the number of the contact surfaces is increased, so that generation of electric heat is reduced. The first wrapping shell and the second wrapping shell are arranged on the outer surface of the conducting rod in a sleeving mode. And a gap is formed between the first wrapping shell and the outer peripheral surface of the first split body, so that the to-be-connected cable is attached to the outer peripheral surface of the first split body.

Description

Technical Field

[0001] The present application relates to the field of electrical engineering technology, and in particular to a cable extension connector. Background Art

[0002] In emergency power supply projects, power supply vehicles serve as the main power generation entity to provide power to the outside. Generally, due to the needs of large-scale power supply projects, power supply vehicles mostly use three-phase electricity, so power supply vehicles often carry at least three conductive cables and at most eight cables. Since most of the load space of the power supply vehicle is used to carry the generator, in order to facilitate the carrying of conductive cables, these cables of equal length with thicker diameters are coiled in the remaining space of the power supply vehicle. In fact, in order to cope with the load requirements of high voltage and high current, these cables cannot be bent, which results in the length of each cable not being too long. In some special working environments, it is difficult for the power supply vehicle to reach the power distribution cabinet at the work site, and the length of each cable is insufficient. For this reason, it is necessary to propose a cable extension connector to address the defect of insufficient cable length in traditional emergency power supply projects. Utility Model Content

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] The present application provides a cable extension connector.

[0039] like Figures 1 to 3 As shown, in one embodiment of the present application, a cable extension connector includes a conductive rod 100 , a first wrapping shell 200 and a second wrapping shell 300 .

[0040] The conductive rod 100 includes a first split body 110, a second split body 120 and a third split body 130. The first split body 110, the second split body 120 and the third split body 130 are fixedly connected in sequence. The first split body 110 and the third split body 130 have the same structure. The first split body 110 is provided with a first ring body 111 and a second ring body 112. The first ring body 111 is arranged on the outer peripheral surface of the first split body 110, and the second ring body 112 is arranged on the outer peripheral surface of the first split body 110. The first ring body 111 is arranged in the middle of the first split body 110, and the second ring body 112 is arranged close to the second split body 120. The first split body 110 is provided with a receiving cavity 113, and the receiving cavity 113 is used to receive cables to be connected.

[0041] The first attachment shell 200 is attached to the outer surface of the first split body 110 , and a preset portion of the first attachment shell 200 is clamped on the outer surface of the second split body 120 .

[0042] The second attachment shell 300 is attached to the outer surface of the third split body 130 , a preset portion of the second attachment shell 300 is clamped on the outer surface of the second split body 120 , and the first attachment shell 200 and the second attachment shell 300 are clamped with each other.

[0043] The present application relates to a cable extension connector, which is fixedly connected to the first split body 110 and the third split body 130 at both ends of the second split body 120 to form a conductive rod 100. The conductive rod 100 is the conductive body of the cable extension connector, and the two cable ports to be connected are electrically connected to the first split body 110 and the third split body 130 respectively, so as to realize the electrical connection of the two cables to be connected. This solves the defect of insufficient cable length in traditional emergency power supply projects. More specifically, the first split body 110 and the third split body 130 have the same structure, which realizes the consistent electrical contact of the two cables to be connected and reduces the probability of harmonic generation in the electrical circuit. In fact, the first split body 110 has two contact surfaces with a cable to be connected, one contact surface is the inner surface of the accommodating cavity 113, and the other contact surface is the outer peripheral surface of the first split body 110. Increasing the contact surface is conducive to reducing the generation of electric heat. The first attached shell 200 and the second attached shell 300 are both sleeved on the outer surface of the conductive rod 100 to provide an insulated gripping position for the operator. It is worth mentioning that there is a gap between the first wrapping shell 200 and the outer circumference of the first split body 110 so that the cable to be connected can be attached to the outer circumference of the first split body 110 .

[0044] like Figures 1 to 3 As shown, in one embodiment of the present application, the first wrapping shell 200 includes a first shell 210, a second shell 220 and a third shell 230. The first shell 210, the second shell 220 and the third shell 230 are fixedly connected in sequence. The inner diameter of the first shell 210 is greater than the outer diameter of the first ring body 111. The inner diameter of the first shell 210 is greater than the inner diameter of the second shell 220.

[0045] Specifically, the first shell 210 is used to wrap the first split body 110, and there is a gap between the first shell 210 and the outer circumference of the first split body 110 for accommodating the tubular cable connector. It is worth mentioning that the cable connector is a tubular cable connector wrapped around the outer circumference of the central column.

[0046] The inner surface of the second shell 220 is provided with a first inner ring body 221. The first inner ring body 221 is fixedly connected to the inner surface of the second shell 220. The first inner ring body 221 is clamped at the connection between the first split body 110 and the second split body 120.

[0047] Specifically, in order to prevent the relative displacement of the conductive rod 100 and the first attached shell 200 during the plugging and unplugging of the cable connector, which may cause an electric shock accident, the first inner ring body 221 can be clamped at the connection between the first split body and the second split body 120.

[0048] In an embodiment of the present application, the second housing 220 is provided with a plurality of first locking blocks 222. The outer surface of the second split body 120 is provided with a rectangular surface 121. Each of the first locking blocks 222 is attached to the rectangular surface 121.

[0049] In an embodiment of the present application, the inner diameter of the third shell 230 is greater than the equivalent diameter of the second split body 120 .

[0050] Specifically, the second housing 220 is provided with a plurality of first clamping blocks 222 for clamping the rectangular surface 121. This is because the first split body 110 is provided with a clamping slot 114 at one end away from the second split body 120. The clamping slot 114 is used to clamp the cable to be connected. In the process of clamping the cable, the cable extension connector needs to be rotated so that the clamping slot 114 clamps the cable to be connected. In this process, the first clamping block 222 clamps the rectangular surface 121, which is conducive to the first split body 110 and the second split body 120 to obtain a force point without slipping.

[0051] like Figures 1 to 3 As shown, in one embodiment of the present application, the second attachment shell 300 includes a fourth shell 310, a fifth shell 320 and a sixth shell 330. The fourth shell 310, the fifth shell 320 and the sixth shell 330 are fixedly connected in sequence. The inner diameter of the fourth shell 310 is greater than the outer diameter of the first ring body 111. The inner diameter of the fourth shell 310 is greater than the inner diameter of the fifth shell 320.

[0052] In one embodiment of the present application, a second inner ring 321 is disposed on the inner surface of the fifth housing 320. The second inner ring 321 is fixedly connected to the inner surface of the fifth housing 320. The second inner ring 321 is clamped at the connection between the third sub-body 130 and the second sub-body 120.

[0053] In an embodiment of the present application, the fifth housing 320 is provided with a plurality of second locking blocks 322 . Each of the second locking blocks 322 is attached to the rectangular surface 121 .

[0054] The first split body 110 and the third split body 130 have the same structure. A slot 114 is provided at one end of the first split body 110 away from the second split body 120 . The slot 114 is used to hold a cable to be connected.

[0055] Specifically, the fourth housing 310 is used to wrap the third sub-body 130, and there is a gap between the outer circumference of the fourth housing 310 and the third sub-body 130 for accommodating a tubular cable connector. It is worth mentioning that the cable connector is a tubular cable connector wrapped around the outer circumference of the central column.

[0056] In order to prevent the conductive rod 100 and the second attached shell 300 from relative displacement during the plugging and unplugging of the cable connector, which may cause an electric shock accident, the second inner ring body 321 can be clamped at the connection between the third body and the second body 120.

[0057] The fifth housing 320 is provided with a plurality of second locking blocks 322 for locking the rectangular surface 121 .

[0058] In one embodiment of the present application, a slot 114 is provided at one end of the third body 130 away from the second body 120, and the slot 114 is used to clamp the cable to be connected. In the process of clamping the cable, the cable extension connector needs to be rotated so that the slot 114 clamps the cable to be connected. In this process, the second clamping block 322 clamps the rectangular surface 121, which is conducive to the third body 130 and the second body 120 to obtain a force point without slipping.

[0059] In one embodiment of the present application, the inner diameter of the sixth housing 330 is greater than the equivalent diameter of the second split body 120. The outer diameter of the sixth housing 330 is equal to the inner diameter of the third housing 230.

[0060] More specifically, the third housing 230 is sleeved on the outer circumference of the sixth housing 330, achieving the function of insulating and sealing the conductive rod 100. In actual application, the outer circumferences of the fifth housing 320 and the second housing 220 are sleeved with phase color rings 400 to remind the operator of the correctness of the three-phase power line connection.

[0061] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
