Description

Technical Field

[0001] The invention relates to a design technology for interconnecting modules in a device, and in particular to a spring cable suitable for interconnecting modules in the device. Background Art

[0002] With the continuous development of technology, some equipment has gradually adopted modular design and installation methods. The internal modules of the equipment are independent in structure and are interconnected according to different functional requirements and specifications during actual use. Since the modules are independent of each other, there is not enough space to lay the electrical interconnection system when the equipment is installed as a whole, and each module in the equipment will reserve a bend for laying the electrical interconnection system before design. However, according to the spatial structure requirements, the length of the cable of the electrical interconnection system is required to be longer than the bend during actual installation. After the modules are connected, the cable needs to be able to be recycled into the bend.

[0003] In view of this, it is necessary to design a cable suitable for interconnecting modules in the device. Summary of the invention

[0004] In order to realize interconnection between various modules within the limited space of the equipment, the present invention discloses a spring cable suitable for interconnecting various modules in the equipment, the spring cable comprising a first connector, a spring wire harness, a laying elbow and a second connector, the spring wire harness being laid in the laying elbow and comprising a spring segment, a first straight segment connected to the first connector and a second straight segment connected to the second connector.

[0005] Furthermore, a connection between the first straight line segment and the first connector, and a connection between the second straight line segment and the second connector are both provided with a heat shrink protective sleeve or potting glue.

[0006] Furthermore, the spring wiring harness includes a power signal wiring harness, a command signal wiring harness and a power detection signal wiring harness.

[0007] Furthermore, the outside of the spring wire harness is wrapped with a signal shielding layer.

[0008] Furthermore, the laid elbow is a metal elbow.

[0009] Furthermore, the ratio of the initial length to the stretched length of the spring harness is 6:10 to 8:10.

[0010] Furthermore, both the first connector and the second connector are provided with arc-shaped buckles.

[0011] Compared with the prior art, the beneficial effects achieved by at least one of the above technical solutions adopted in the embodiments of this specification include at least the following: the spring cable of the present invention does not need to be fixed by structures such as clamps, which can save laying space; the elasticity of the spring segment facilitates the docking installation of the interface, and the spring segment can be retracted into the laying elbow after the docking is completed.

[0015] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0016] The following describes the implementation methods of the present application through specific specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and the features of the embodiments can be combined with each other in the absence of conflict. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0017] In the description of this embodiment, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the invention.

[0018] In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0019] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present disclosure. The illustrations only show components related to the present disclosure rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0020] The embodiment of the present invention discloses a spring cable suitable for interconnecting modules in a device, see Figure 1 As shown, the spring cable includes a first connector 1, a spring harness 2, a laying elbow and a second connector 3. The spring harness 2 is laid in the laying elbow and includes a spring segment 21, a first straight segment 22 connected to the first connector 1, and a second straight segment 23 connected to the second connector 3. In specific implementation, the outer diameter of the spring cable, the outer diameter of the spring harness 2, and the inner harness diameter structure of the spring harness 2 can be adjusted according to actual requirements. At the same time, the laying elbow can be designed according to the actual laying path, its size and electrical principle.

[0021] Furthermore, when designing the spring cable, in order to ensure that the spring harness 2 can be smoothly passed through the laying bend and avoid damage to the spring harness 2, when the spring harness 2 and the first connector 1 and the second connector 3 at both ends are connected to form a whole, a heat shrink protective tube or potting glue is used to fix and protect the connection. Figure 1 As shown, the connection between the first straight segment 22 and the first connector 1 , and the connection between the second straight segment 23 and the second connector 3 are both provided with a heat shrink protective sleeve 4 or potting glue.

[0022] Further, specifically, the spring harness 2 must meet the requirements of pipe installation, signal transmission quantity, electromagnetic shielding function and current carrying capacity when designing and selecting the structure of the spring harness 2. The number of harnesses and shielding structure in the spring harness 2 can be designed. Specifically, the spring harness 2 includes a power signal harness, a command signal harness and a power detection signal harness, and the current carrying capacity of each harness can be designed to be 3A.

[0023] Furthermore, the outside of the spring harness 2 is wrapped with a signal shielding layer, and the power signal harness, the command signal harness and the power detection signal harness can also be wrapped with shielding layers respectively for signal isolation.

[0024] Furthermore, the model and specification of the wiring harness can also be pasted on the power signal wiring harness, the command signal wiring harness and the power detection signal wiring harness.

[0025] Furthermore, the laid elbow is a metal elbow. During design, the inner diameter of the metal elbow can be designed to be 14 mm, the length can be designed to be 800 mm, and the turning radius of the elbow can be designed to be 135 mm.

[0026] Further, in order to ensure the telescopic performance of the spring harness 2, the ratio of the initial length to the stretched length of the spring harness 2 in the embodiment of the present invention is 6:10 to 8:10, and the ratio of the two is preferably 7:10, for example Figure 1 As shown, when the initial length of the spring harness 2 is 700 mm, its stretched length is correspondingly 1000 mm.

[0027] Furthermore, the first connector 1 and the second connector 3 are both provided with an arc-shaped buckle 5, and the two modules can be conveniently and quickly interconnected by a spring cable through the arc-shaped buckle 5.

[0028] Further, in order to ensure that the spring harness 2 can be smoothly laid in the laying elbow, it is necessary to control the overall size of the potting section (or heat shrink protection tube) after the first connector 1 is connected to the first straight section 22, and the potting section (or heat shrink protection tube) of the second connector 3 and the second straight section 23, for example, see Figure 1 As shown, the length between the first connector 1 and the potting section (or the heat shrink protection tube) can be controlled within 35 to 28 mm.

[0029] When the spring harness 2 is installed in the laying elbow, the first connector 1 or the second connector 3 can be dragged and pulled by a metal wire, so that the spring harness 2 is placed in the laying elbow after the first connector 1 or the second connector 3 passes through the laying elbow.

[0030] The spring cable of the present invention does not need to be fixed by structures such as clamps, which can save laying space; the elasticity of the spring segment facilitates the docking installation of the interface, and the spring segment can be retracted into the laying elbow after the docking is completed. At the same time, the independently arranged laying cable is also convenient for replacement when the cable is abnormal. At the same time, the spring cable of the present invention has the variability of length, and the wire harness of the same specification can be used in modular design equipment of different specifications, which greatly improves the application range of the spring cable.

[0031] Obviously, those skilled in the art should understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the embodiments of the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
