Description

Technical Field

[0001] The utility model relates to the technical field, and in particular to a structure for fixing and connecting flat cables. Background Art

[0002] In the application of instrumentation equipment, it is often necessary to interconnect and convert signals through various connectors and connecting wires. Some signal transmissions involve very precise high-speed transmission connections. Due to the high performance requirements, high-speed connectors like this have relatively high production process requirements and high precision. When using similar connectors, in addition to the original assembly accuracy between the connector and the connecting cable, it is also necessary to consider the loose connection caused by the use environment and transportation after assembly, which may lead to problems such as obstruction of signal transmission.

[0003] Generally, the wider the functionality of instrumentation equipment, the more built-in devices and modules there are. The connection between various modules involves various connectors and connecting cables. The layout inside the chassis is subject to the overall size of the chassis. Therefore, when the internal space of the chassis is effectively utilized, connectors in all directions will exist. Some connecting cables can only be connected downward in structure. The way of connecting the connector downward is more likely to loosen or even fall off when the equipment vibrates during operation or during transportation. There are also some high-speed transmission connecting cables, which are not suitable for connecting to the port on the chassis first and then connecting to other devices through the port due to performance requirements. This situation is generally that one end of the high-speed connecting cable is connected to the terminal on the PCB, and the other end goes straight out of the chassis. Since the high-speed cable is exposed outside the chassis, it is often pulled when connecting other devices, which can easily cause the connection inside the chassis to loosen, causing the equipment to fail to operate. For this type of connection, if there is no reliable fixing method, in serious cases, the module inside the device may be damaged.

[0004] Therefore, improvements need to be made. Utility Model Content

[0005] The technical problem solved by the present invention is to provide a structure for fixing the connecting cable in view of the defects existing in the above-mentioned prior art. The main purpose of the present invention is to add a corresponding structure at the position of the connecting cable to improve the connection firmness between the connecting cable and the module, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a structure for fixing a connecting cable, comprising: a chassis, an installation space is set in the chassis; a base, the base is installed on the inner wall of the chassis; a module, the module is installed on the base; a column, there are more than one column, and the column is arranged around the module; a pressure plate, the pressure plate is connected to the end of the column, and the pressure plate is provided with more than one opening for the connecting cable to pass through; a connecting cable, one end of the connecting cable is connected to the module, and the other end of the connecting cable extends to the outside of the chassis through the opening; wherein the pressure plate is used to press the position of the connecting cable.

[0007] Furthermore, a limit block is provided on the inner wall of the chassis above the module, and the limit block is provided with one or more notches for limiting the range of movement of the connecting cable, and the connecting cable extends out of the chassis through the notches.

[0008] Furthermore, there are four columns, which are respectively arranged around the module, and the pressure plate is connected and fixed to the columns by screws.

[0009] Furthermore, the limit block is connected and fixed to the inner wall of the chassis by screws.

[0010] Compared with the prior art, the beneficial effect of the present invention is that by providing a column and a pressure plate, the installation position of the connecting cable and the module is pressed and reinforced to prevent the connecting cable from falling off during transportation, vibration, pulling, etc.

[0011] At the same time, a limit block is added to limit the bending range of the connecting cable, thereby avoiding excessive bending of the connecting cable itself and ensuring the safety and stability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] The embodiments described with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and cannot be understood as limiting the present application. In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meanings of "several" and "multiple" are two or more, unless otherwise clearly and specifically defined. In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. In this application, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature can include the first and second features being in direct contact, or it can include the first and second features not being in direct contact but being in contact through another feature between them. Moreover, the first feature "above", "above" and "above" the second feature include the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature "below", "below" and "below" the second feature include the first feature being directly above and obliquely above the second feature, or simply means that the first feature is lower in level than the second feature.

[0020] like Figure 1-5As shown, a structure for fixing a connecting cable is provided, comprising: a chassis, wherein an installation space is provided inside the chassis; a base, wherein the base is installed on the inner wall of the chassis; a module, wherein the module is installed on the base; a column, wherein there is more than one column, and the column is arranged around the module; a pressure plate, wherein the pressure plate is connected to the end of the column, and wherein the pressure plate is provided with more than one opening for the connecting cable to pass through; a connecting cable, wherein one end of the connecting cable is connected to the module, and the other end of the connecting cable extends to the outside of the chassis through the opening; wherein the pressure plate is used to press and hold the position of the connecting cable.

[0021] Since the existing connection cables are directly connected to the modules in the chassis by direct plug-in, some special high-speed transmission cables need to be extended out of the chassis to connect with other devices, which may cause the cables to be pulled off easily.

[0022] In this regard, in order to improve the stability of the connection between the connecting cable and the module inside the chassis, a column is arranged at the peripheral position of the module, a pressure plate is installed on the upper end of the column, and an opening is arranged on the pressure plate. To facilitate the installation of the connecting cable, the opening position extends to the edge of the pressure plate. When the connecting cable is connected to the module, the pressure plate presses the connecting end of the connecting cable, thereby improving the stability of the connection between the connecting cable and the module. Under the pulling of external force, the connecting cable is not easy to fall off from the module position, thereby ensuring the normal operation of the equipment.

[0023] like Figure 3-4 As shown, a limit block is provided on the inner wall of the chassis above the module, and the limit block is provided with one or more notches for limiting the range of movement of the connecting cable, and the connecting cable extends out of the chassis through the notches.

[0024] Since the connecting cables usually need to be led out of the chassis to connect to the equipment, there are many straight-out connecting cables. The original material of the connecting cables has a minimum bending parameter. In addition to ensuring the structural strength of the connector end, it is necessary to consider the degree of bending of the connecting cables when they are led out of the chassis. For example, when the bending of the connecting cables is too large, it will cause excessive force on the tail end of the connector.

[0025] In this regard, the chassis sets a limit block at the position where the connecting cable is led out. A notch is set on the limit block. The notch can be selected according to the implementation situation. The size of the notch must be sufficient to allow the connecting cable to pass through, so as to prevent the connecting cable from shaking too much, causing excessive force on the connecting port and causing damage to the entire module.

[0026] Specifically, there are four columns, which are respectively arranged around the module, and the pressure plate is connected and fixed to the columns by screws.

[0027] Preferably, four columns are used, specifically single-head hexagonal nut columns, and the four columns form a basis for installing a pressure plate. The end of the connecting cable is connected to the module by means of screw locking. Specifically, the lower bottom surface of the pressure plate contacts the end of the connecting cable to prevent the end of the connecting cable from falling off the module under the action of external force.

[0028] Specifically, the limit block is connected and fixed to the inner wall of the chassis by screws.

[0029] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
