Description

Technical Field

[0001] The utility model belongs to the technical field of cables, and more specifically, particularly relates to a series-connected flat cable. Background Art

[0002] A series-connected flat cable is a flat cable product composed of multiple insulated wires arranged in parallel and combined in a specific manner (such as series connection), and is widely used in fields such as automotive electronics, electronic devices, and industrial automation. Existing series-connected flat cables generally consist of a cable body and interface terminals at both ends.

[0003] Based on the above, when the input port of a series-connected flat cable is tightly connected to other devices, if the electrical components connected by the terminals encounter abnormal situations such as circuit overload or short circuit, since the cable itself does not have a direct fault response mechanism, it cannot make a protective reaction immediately. In this case, the fault current or abnormal signal may be directly conducted to the connected device without effective blocking, thereby increasing the risk of device damage or failure. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a series-connected flat cable to solve the problem that when the input port of an existing series-connected flat cable is tightly connected to other devices, if the electrical components connected by the terminals encounter abnormal situations such as circuit overload or short circuit, since the cable itself does not have a direct fault response mechanism, it cannot make a protective reaction immediately. In this case, the fault current or abnormal signal may be directly conducted to the connected device without effective blocking, thereby increasing the risk of device damage or failure.

[0005] The purpose and effect of a series-connected flat cable of the utility model are achieved by the following specific technical means:

[0006] A series-connected flat cable includes a lower sleeve;

[0007] An upper cover, the upper cover is fixedly connected to the right side of the lower sleeve;

[0008] Main cables, four main cables are provided, and the four main cables are dispersedly arranged inside the lower sleeve and the upper cover. Among them, the two lower main cables are each divided into two strands inside the upper cover;

[0009] Combined cables, two combined cables are provided, and each combined cable is composed of one strand of each of the two lower main cables combined;

[0010] DC sockets, the DC sockets are fixedly connected to the left ends of the two lower main cables;

[0011] A second connection housing, the second connection housing is fixedly connected to the right end of one of the upper combined cables;

[0012] The third connection housing, which is fixedly connected to the right end of the lower combined cable;

[0013] The left port assembly, which is arranged at the left ends of the upper two main cables;

[0014] The right port assembly, which is arranged at the right ends of the upper two main cables and the two combined cables.

[0015] Further, the left port assembly includes:

[0016] The third terminals, two of which are arranged and fixedly connected to the left ends of the upper two main cables respectively;

[0017] The sleeves, two of which are arranged and sleeved outside the two third terminals respectively;

[0018] The fuse boxes, two of which are arranged and fixedly connected to the left sides of the two sleeves respectively.

[0019] Further, the left port assembly also includes:

[0020] The fuses, two of which are arranged and dispersed inside the two fuse boxes;

[0021] The first terminals, two of which are arranged and fixedly connected to the left sides of the cables extending from the two fuse boxes respectively.

[0022] Further, the left port assembly also includes:

[0023] The labels, two of which are arranged and dispersed and fixedly connected to the outside of the cables extending from the two fuse boxes.

[0024] Further, the right port assembly includes:

[0025] The first connection housings, two of which are arranged and fixedly connected to the right ends of the upper two main cables respectively.

[0026] Further, the right port assembly also includes:

[0028] The nuts, two of which are arranged and sleeved outside the two groups of second terminals respectively;

[0029] Sealing rings, two sealing rings are provided, and the two sealing rings are respectively sleeved outside the two second terminals.

[0030] Compared with the prior art, the utility model has the following beneficial effects:

[0031] First, a fuse box is provided. When the current in the circuit of the electrical component connected to the first terminal is overloaded, short-circuited, etc., the fuse melts, timely cutting off the current transmission. This not only cuts off the transmission path of the abnormal current, but also significantly reduces the risk of potential damage to the equipment caused by out-of-control current, thus ensuring the safety and stability of the entire circuit system. During production, a transparent protective sleeve is wrapped outside the first terminal to avoid damage during transportation.

[0032] Second, the two first cables below are recombined into two combined cables. Then, by connecting the two second terminals to two second connection housings and a third connection housing of different models, the usage range is expanded, making it convenient for more different types of equipment to use. The sealing rings can prevent the second terminals from directly contacting the outside world and being damaged during transportation.

[0033] When the current in the circuit of the electrical component connected to the first terminal of the utility model is overloaded, short-circuited, etc., the fuse in the fuse box melts in time, avoiding subsequent adverse effects. By recombining the two first cables into two combined cables, the usage range is expanded. The protective sleeve wrapped outside the first terminal and the sealing rings outside the second terminals can prevent the first terminal and the second terminals from being damaged due to bumps during transportation.
