Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a cable connector for reducing line loss. Background Technology

[0002] In the field of power transmission, cable joints are key components for connecting cable segments and ensuring line continuity, and their performance has a profound impact on power transmission efficiency and stability. Currently, conventional cable joints mostly use a connection method where the terminal block is fastened to the cable core with bolts. This traditional method has revealed many drawbacks in practical applications: on the one hand, the operation process is cumbersome, requiring a lot of manpower and time for tightening and loosening bolts during installation and maintenance, greatly reducing work efficiency; on the other hand, the limited contact area after connection results in a reduced current-carrying diameter of the connection part. According to the resistance calculation formula, a smaller cross-sectional area leads to increased resistance, which in turn increases line loss, not only wasting energy but also potentially affecting the overall operational stability and reliability of the power system.

[0003] Therefore, those skilled in the art have provided a cable connector for reducing line loss to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cable connector for reducing line loss. It utilizes a copper alloy material and precise dimensional design to enhance mechanical strength and conductivity, increase contact area, and reduce resistance and line loss. The tapered inlet and connecting groove simplify the installation process and improve construction efficiency. An insulating rubber outer sleeve ensures insulation and connection stability, guaranteeing safe use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cable connector for reducing line loss includes:

[0007] The first connector is used to fix one end of the cable to be connected, including a first terminal, a first limiting groove is provided at the lower end of the first terminal near the middle position, and a first contact groove is provided on one side of the first limiting groove.

[0008] The second connector is used to fix one end of another cable to be connected. It includes a second terminal, a second limiting groove is provided inside the upper end of the second terminal near the middle position, and a second contact groove is provided on one side of the second limiting groove.

[0009] The outer sleeve is fixed and slidably fitted onto the outside of the first and second connecting parts to achieve limiting.

[0010] Furthermore, a first wire inlet is provided inside the end of the first terminal near the first contact groove. The outer inner diameter of the first wire inlet is larger than the inner inner diameter to facilitate wire entry.

[0011] Furthermore, a first wire-passing groove is provided at the end of the first terminal away from the first contact groove.

[0012] Furthermore, a second inlet is provided on the side of the second terminal away from the second contact groove. The outer inner diameter of the second inlet is larger than the inner inner diameter to facilitate wire entry.

[0013] Furthermore, a second wire-passing groove is provided on the side of the second terminal near the second contact groove.

[0014] Furthermore, a connecting groove is provided on the upper side of the end of the second terminal near the second contact groove to facilitate the installation of the first connector and the second connector.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a cable connector for reducing line loss. The cable ends at both ends are tightly pressed together by a first contact groove and a second contact groove, significantly increasing the contact area compared to traditional bolt fastening. Based on the inverse relationship between resistance and cross-sectional area, the increased contact area effectively reduces the resistance at the connection point, minimizing energy loss during transmission, improving power transmission efficiency, meeting the development needs of energy conservation and emission reduction, and helping to reduce power operating costs.

[0017] 2. This utility model proposes a cable connector for reducing line loss. During installation, simply insert the cable ends on both sides through the first and second inlets into the first and second cable grooves respectively, press the cable ends flat on the corresponding contact grooves, align the first and second terminals with the limiting grooves, and finally put on the fixing sleeve to complete the installation. The entire process is simple to operate, requiring no complicated tools or cumbersome bolt tightening steps, greatly shortening the installation time, improving the efficiency of construction and maintenance, and facilitating the rapid deployment of power lines and timely handling of line faults.

Detailed Implementation

[0024] 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.

[0025] Reference Figure 1-4 This utility model provides an embodiment of a cable connector for reducing line loss, comprising: a first connector 2 for fixing one end of a cable to be connected, including a first terminal 201. The first terminal 201 is made of high-strength, high-conductivity copper alloy, with a diameter of 20mm and a length of 50mm, ensuring sufficient mechanical strength and conductivity when carrying large currents. A first limiting groove 204 is provided at the lower end of the first terminal 201 near the middle position, with a groove depth of 8mm and a groove width of 10mm. This size is adapted to the size of the second terminal 303 for precise engagement and positioning. A first contact groove 202 is provided on one side of the first limiting groove 204. The cross-section of the contact groove is rectangular, with dimensions of 15mm in length and 8mm in width, increasing the contact area with the cable end. The first terminal 201, near the first contact groove 202, has a first cable inlet 203. The outer inner diameter of the first cable inlet 203 is designed to be 12mm, and the inner inner diameter is 8mm, with a tapered transition. This design facilitates the entry of cables of different specifications and reduces the frictional resistance when the cable is inserted. The first terminal 201, away from the first contact groove 202, has a first cable passage 205. The passage is 8mm wide and extends through the first terminal 201, providing a stable cable passage.

[0026] Specifically, the first terminal 201 guides the cable into position accurately through the cooperation of the first inlet 203 and the first cable groove 205. The first limiting groove 204 cooperates with the second limiting groove 306 of the second connector 3 to achieve positioning. The first contact groove 202 provides a large conductive contact area for the cable end. Thus, the high-strength, highly conductive material and precise size design not only ensure the stability of the mechanical connection, but also reduce resistance and line loss by increasing the contact area. The tapered inlet facilitates installation and improves construction efficiency.

[0027] The second connector 3 is used to fix one end of another cable to be connected, and includes a second terminal 303. The second terminal 303 is also made of copper alloy, with a diameter of 20mm (the same as the first terminal 201) and a length of 48mm. A second limiting groove 306, 8mm deep and 10mm wide, is formed inside the upper part of the second terminal 303 near the middle, corresponding to the first limiting groove 204. A second contact groove 301, with the same dimensions as the first contact groove 202, is formed on one side of the second limiting groove 306 to ensure consistent contact area at both ends. A second cable inlet 305, with an outer inner diameter of 12mm and an inner inner diameter of 8mm, is formed on the side of the second terminal 303 away from the second contact groove 301, facilitating cable insertion. A second wire-passing groove 304, 8mm wide, is formed on the side of the second terminal 303 near the second contact groove 301, penetrating the second terminal 303.

[0028] A connecting groove 302 is provided on the upper side of the end of the second terminal 303 near the second contact groove 301. The groove angle is 45° and the groove length is 10mm. When the first connector 2 and the second connector 3 are installed, the groove can guide the first terminal 201 to smoothly enter the second limiting groove 306.

[0029] Specifically, the second terminal 303 and the first terminal 201 are symmetrical in structure and size-matched. The cable is fixed through the second inlet 305 and the second cable groove 304. The connecting groove 302 assists in engaging with the first connector 2. The second contact groove 301 and the first contact groove 202 together form a large-area conductive contact surface. Thus, the symmetrical design and precise size matching ensure the tightness and stability of the connection. The setting of the connecting groove 302 simplifies the engagement process and improves installation efficiency. The contact grooves of the same specification ensure the consistency of conductivity and effectively reduce line loss.

[0030] The fixing sleeve 1 is made of insulating rubber with a certain degree of elasticity. Its inner diameter is 22mm, which is slightly larger than the outer diameter of the first connector 2 and the second connector 3 combined, ensuring a tight fit. The fixing sleeve 1 is 60mm long, which can completely cover the engagement part of the first connector 2 and the second connector 3.

[0031] Specifically, the fixing sleeve 1, through elastic deformation, tightly fits onto the outside of the first connector 2 and the second connector 3 after they are engaged. The friction generated by the elasticity of the rubber limits and fixes the first connector 2 and the second connector 3, preventing them from loosening. The insulating rubber material ensures the insulation performance of the joint and avoids the risk of leakage. The appropriate size design ensures that the fixing sleeve 1 can tightly fix the connector without affecting the conductivity of the connector due to excessive tightness, further ensuring the stability and safety of the cable joint connection.

[0032] Working Principle: During cable connection, the construction personnel first process the two cables to be connected separately, passing the cable ends sequentially through the first inlet 203 and the second inlet 305. Since both the first inlet 203 and the second inlet 305 are designed with an outer inner diameter larger than the inner inner diameter, the cable insertion is facilitated. After insertion, the cable end is pulled out along the direction of the first through-groove 205 and the second through-groove 304, and pressed flat onto the first contact groove 202 and the second contact groove 301. At this point, the first terminal 201 of the first connector 2 is aligned with the second limiting groove 306 of the second connector 3, and the second terminal 303 of the second connector 3 is aligned with the first limiting groove 204 of the first connector 2 for engagement. During engagement, the connecting groove 302 on the second terminal 303 plays a role, providing guidance for the alignment and engagement of the first terminal 201 and the second terminal 303, reducing engagement difficulty and improving installation convenience. After the first terminal 201 and the second terminal 303 are successfully engaged, the ends of the two cables are tightly fitted together by the two contact grooves. Finally, the fixing sleeve 1 is slidably fitted onto the outside of the first connector 2 and the second connector 3. The fixing sleeve 1 acts as a limit, further ensuring the stability of the connection between the first connector 2 and the second connector 3, keeping the ends of the cables tightly compressed at all times. This achieves a large-area conductive contact, completing the connection of the entire cable joint and ensuring that power can be transmitted efficiently and stably through the joint.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
