Description

Technical Field

[0001] This utility model relates to the field of power system technology, specifically to a C-type bus connector. Background Technology

[0002] In photovoltaic power generation systems, the rectification and collection of DC-side cables are crucial for ensuring efficient power transmission. Since the current output from photovoltaic modules needs to pass through multiple collection stages before finally connecting to the inverter, this process often involves the transition from large-diameter cables to small-diameter cables, and multiple small-diameter cables may need to be connected to the same connection point simultaneously.

[0003] The shortcomings of existing technology:

[0004] Currently, the industry commonly uses traditional H-type clamps for cable connections. Their structure features double grooves on the top and bottom, allowing only two cables to be connected at a time. However, in photovoltaic rectification scenarios, if multiple cables need to be connected, multiple H-type clamps must be installed side-by-side. This not only results in a large installation space requirement and messy wiring, but also introduces additional contact resistance due to the increased number of connection points, affecting system efficiency. Furthermore, uneven crimping may cause localized overheating, increasing the risk of failure. Utility Model Content

[0005] The purpose of this invention is to provide a C-type bus connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a C-type bus connector, comprising a clamp body, the clamp body having a C-shaped structure, and the clamp body having a cable groove for installing cables inside, the cable groove including a branch cable groove for installing branch cables, the branch cable groove being opened along the axial direction of the clamp body on the inner sidewall of the clamp body; and the branch cable groove covering the branch cable after being pressed together.

[0007] By adopting the above technical solution, after pressing, the branch cable can make uniform and effective contact with the clamp body. The branch cable is easy to install, the wiring is neat, local overheating is avoided, the conductivity is improved, and the branch cable tray can tightly wrap the branch cable.

[0008] Preferably, the cable groove further includes a main cable groove, which is integrally formed inside the clamp body for installing the main cable; and the branch cables are distributed along the circumference of the main cable after the clamp body is pressed by a mold.

[0009] By adopting the above technical solution, after pressing, the branch cables are evenly distributed around the circumference of the main cable, and the branch cables and the main cable can make effective contact, ensuring system efficiency.

[0010] Preferably, the number of branch grooves is one or more.

[0011] By adopting the above technical solution, it is easy to install the appropriate number of cables according to the actual operational needs, so as to meet the convergence requirements of various scenarios.

[0012] Preferably, the two ends of the opening of the clamp body are provided with a mating structure for forming a closed loop after the clamp body is pressed together.

[0013] By adopting the above technical solution, it is ensured that the clamp body after crimping forms a closed-loop circular shape, thus guaranteeing the overall strength of the clamp body after crimping.

[0014] Preferably, the mating structure includes a protruding part and a recessed part. The protruding part is integrally formed at one end of the clamp body, and the recessed part is formed at the other end of the clamp body. When the clamp body is pressed, the protruding part is inserted into the recessed part.

[0015] By adopting the above technical solution, the convex part and the concave part cooperate with each other, so that the convex part is stuck inside the concave part, which increases the wrapping performance of the clamp body on the cable and reduces the risk of opening.

[0016] Preferably, the two ends of the opening of the clamp body are provided with a mating structure for forming a closed loop after the clamp body is pressed together, and the mating structure is two planes that are parallel after pressing together.

[0017] By adopting the above technical solution, it is ensured that the two ends of the opening of the clamp body are tightly joined without gaps after pressing.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This type of C-type bus connector has a clamp body integrally formed into a C-shaped structure, and the C-shaped structure has a cable groove for installing cables. The cable groove includes a main cable groove and branch cable grooves. The main cable groove is integrally formed inside the clamp body and is used to install the main cable. Several branch cable grooves are provided inside the clamp body. The clamp body is crimped by a crimping mold, so that the clamp body wraps the main cable inside. After crimping, the main cable and the branch cable are in direct contact, which improves the conductivity and requires less installation space, resulting in neat wiring.

[0020] 2. This type of C-type bus connector uses a crimping die to crimp the clamp body. The protruding and concave parts on both sides of the opening of the clamp body cooperate with each other to form a closed loop, which increases the clamp body's ability to wrap the cable and reduces the risk of opening.

[0031] Example

[0032] Please see Figure 1-4 As shown, this utility model provides a C-type bus connector, including a clamp body 1. The clamp body 1 has a C-shaped structure, and a cable groove for installing cables is provided inside the clamp body 1. The cable groove includes a branch cable groove 101 for installing branch cables. The branch cable groove 101 is formed along the axial direction of the clamp body 1 on the inner side wall of the clamp body 1. The cross-sectional profile of the branch cable groove 101 is U-shaped, which facilitates the initial installation of branch cables and the wrapping of branch cables after crimping. In other embodiments, the cross-sectional profile of the branch cable groove 101 can also be C-shaped to ensure that the branch cable groove 101 can uniformly wrap the branch cables. In other embodiments, the cross-sectional profile of the branch cable tray 101 can also be U-shaped or any concave shape that can cover the branch cable; the number of branch cable trays 101 is one or more, which facilitates the installation of a corresponding number of cables according to the actual operation requirements and meets the convergence requirements of various scenarios; after pressing, the branch cable can make uniform and effective contact with the clamp body 1, the branch cable is easy to install, the wiring is neat, local overheating is avoided, the conductivity is improved, and the branch cable tray 101 can tightly cover the branch cable; the cable tray also includes a main cable tray 102, which is integrally formed inside the clamp body 1 for installing the main cable; and after the clamp body 1 is pressed by the mold, the branch cable is distributed along the circumferential direction of the main cable.

[0033] Reference Figure 3 In other embodiments, teeth 2 may be provided on the inner sidewall of the clamp body 1. The teeth 2 are used to increase the friction between the cable and the clamp body 1. In other embodiments, protrusions or convex structures that can increase the friction between the cable and the clamp body 1 may be provided on the inner sidewall of the clamp body 1.

[0034] In use, the branch cable is stripped and inserted into the branch cable groove 101, and then the main cable is inserted into the main cable groove 102. The clamp body 1 is then crimped using a crimping die, so that the clamp body 1 wraps the main cable inside. The teeth 2 increase the friction between the cable and the main cable inside the clamp body 1, allowing the clamp body 1 to grip the cable tightly. The teeth 2 will pierce the outer sheath of the cable conductor, improving the connection stability. After crimping, the main cable and the branch cable are in direct contact, improving the conductivity.

[0035] The wire clamp body 1 has mating structures at both ends of its opening for forming a closed loop after the wire clamp body 1 is pressed together. These mating structures include a protruding part 103 and a recessed part 104, which are respectively a locking block and a slot structure. The protruding part 103 is integrally formed at one end of the wire clamp body 1, and the recessed part 104 is formed at the other end. When the wire clamp body 1 is pressed together, the protruding part 103 is inserted into the recessed part 104. The protruding part 103 and the recessed part 104 cooperate with each other, causing the protruding part 103 to be locked within the recessed part 104, increasing the wire clamp body 1's ability to enclose the cable and reducing the risk of opening. (Refer to...) Figure 4 In other embodiments, the protruding portion 103 and the concave portion 104 may also be concave and convex structures, gear-like structures that can mesh with each other, or non-planar structures that can fit together to form a complete closure.

[0036] In use, the clamp body 1 is pressed by a crimping die, and the clamp body 1 is pressed into an O-shape. The locking block and the locking slot cooperate to close the opening of the clamp body 1. The locking slots and locking blocks on both sides of the opening of the clamp body 1 cooperate with each other, so that the locking block is locked inside the locking slot, which increases the clamp body 1's ability to wrap the cable and reduces the risk of opening. In addition, the wall thickness in the middle of the clamp body 1 is greater than the wall thickness on both sides of the opening of the clamp body 1, which increases the clamping force of the clamp body 1, making the opening difficult to open.

[0037] In this embodiment, the wall thickness of the middle part of the clamp body 1 is denoted as a, and the wall thickness on both sides of the opening of the clamp body 1 is denoted as b. A is set to be greater than b, which increases the clamping force of the clamp body 1 and makes the opening less likely to open.

[0038] Example 2

[0039] Please see Figure 1-5 As shown, the present invention provides a C-type bus connector. The structure of the clamp body 1, the branch groove 101 and the main groove 102 are the same as those in embodiment 1. The mating structure consists of two parallel planes after pressing. After being pressed by a mold, the two ends of the opening of the clamp body 1 are tightly joined without gaps, which can tightly cover and combine the branch cables and the main cables.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
