Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a network port expansion switch. Background Art

[0002] A network expansion switch is a network device primarily used to expand the number of ports on a network to connect more devices. This type of switch typically features multiple network ports, providing more connection points and allowing more devices to access the network. It is commonly used in homes, offices, data centers, and other locations to meet network expansion needs.

[0003] When existing households use network port expansion switches, they generally place the network port expansion switches in a weak-current box. The weak-current box in the home is opened in the wall, and the weak-current box is generally small in size. Generally, it can be filled by placing a power supply, a router and a network port expansion switch inside. As a result, the multiple network cables connected to the network port expansion switch inside the weak-current box are not easy to classify due to the small space of the weak-current box, resulting in a messy wire harness in the weak-current box. The messy network cables take up more space, which may also affect the heat dissipation of the network port expansion switch or router, and is not convenient for the later replacement or maintenance of the network cables. Utility Model Content

[0004] In order to solve the technical problems existing in the above background technology, the utility model provides a network port expansion switch.

[0005] The technical solution of this utility model is as follows:

[0006] A network port expansion switch includes a housing, a plurality of RJ-45 interfaces are arranged side by side on a lower side of the housing, a plurality of heat dissipation vents are provided on both the left and right sides of the housing, at least one positioning clip is clamped to the heat dissipation vent on the left or right side of the housing, a ring-shaped cable bundle unit is provided on the side of the positioning clip away from the housing, and the ring-shaped cable bundle unit includes two arc-shaped members that can be fastened to form a ring structure, an end of one arc-shaped member is connected to the positioning clip, opposite ends of the two arc-shaped members are elastically connected by a rebound assembly, and the other opposite ends of the two arc-shaped members can be staggered to form a cable bundle opening;

[0007] The axis of the arc-shaped piece connected to the positioning clip is parallel to the vertical plane where the network cable is plugged into the RJ-45 interface.

[0008] The positioning clip is installed on the heat dissipation outlet, which is convenient for direct installation on the shell and easy replacement of the position of the ring-shaped wiring unit thereon. One of the two arc-shaped parts of the ring-shaped wiring unit is fixedly connected to the positioning clip, and the other can be rotated at a certain angle, so that the two arc-shaped parts can be staggered for placing multiple network cables, and can be reset so that the two network cables can be buckled to form a ring structure to bind and guide the network cables. There will be no multiple network cables distributed in a disorderly manner in the weak-current box, which will occupy a large space and be difficult to repair.

[0009] In order to facilitate the stable bundling and arrangement of multiple network cables plugged into the RJ-45 interface, multiple positioning clips are provided along the length direction of the left or right side of the shell, and multiple positioning clips are provided with annular wiring units, and there are at least two annular wiring units.

[0010] In order to facilitate the pre-guiding and bundling of the roots of multiple network cables, the ring-shaped cable bundle unit located below is set close to the horizontal plane where multiple RJ-45 interfaces are located.

[0011] To facilitate the storage and organization of multiple network cables along one side of the shell, gaskets are provided on the inner sides of the two arc-shaped parts of a ring-shaped cable harness unit away from the RJ-45 interface. The gaskets reduce the size of the ring structure formed by the two arc-shaped parts away from the RJ-45 interface, so that multiple network cables can be clamped on the side of the shell away from the RJ-45 interface, reducing the phenomenon of scattered network cables.

[0012] The material and thickness of the above-mentioned gasket are: the gasket is made of non-slip rubber material, and its thickness is 0.2-0.5cm. The thickness of the gasket is adjusted according to the number of network cables plugged into the switch. It can clamp the multiple plugged network cables and reduce the shaking of the network cables in a ring harness unit away from the RJ-45 interface.

[0013] Regarding the connection structure of the corresponding two arc-shaped parts, the ends of the two connected arc-shaped parts are rotatably connected through a rotating shaft, and a torsion spring is sleeved on the rotating shaft. The two ends of the torsion spring are respectively connected to the ends of the two arc-shaped parts. One of the arc-shaped parts is connected to the positioning clamp and the position is fixed. The other arc-shaped part can be rotated up or down by a certain angle with the rotating shaft as the rotation axis, and staggered with the fixed arc-shaped part to form a structure for placing the network cable.

[0014] The structure of the above-mentioned rebound assembly is that the rebound assembly includes a rotating shaft and a torsion spring, and the ends of the two connected arc-shaped parts are each provided with a long groove, the rotating shaft is rotatably set in the long grooves of the two arc-shaped parts, and both ends of the torsion spring are located in the long grooves of the two arc-shaped parts.

[0015] In order to facilitate the limiting effect of the rotatable arc-shaped part, so that the network cable can be placed inside the two arc-shaped parts after rotation, after the torsion spring is reset, it can be buckled with the arc-shaped part in a fixed position to form a ring structure, thereby realizing the limiting of multiple network cables. A limiting plate is provided above the end of an arc-shaped part connected to the positioning clamp away from the long slot, and the limiting plate extends toward the end of the other arc-shaped plate away from the long slot.

[0016] The specific structure of the above-mentioned positioning clip is that the positioning clip is made of elastic plastic material, and is provided with a clamping opening with an open side along the transverse direction. The clamping opening has an upper clamping surface and a lower clamping surface arranged in parallel. The upper clamping surface and the lower clamping surface are both provided with multiple clamping protrusions at intervals in the length direction of the flue gas, and the spacing between two adjacent clamping protrusions on the same surface is consistent with the thickness of the heat dissipation port of the shell.

[0017] The beneficial effects of the present invention are:

[0018] A positioning clip is provided on the side of the housing where the heat dissipation vent is provided, eliminating the need to perform operations such as drilling holes in the housing of the existing network port expansion switch, and does not affect the structural strength of the housing;

[0019] The positioning clip can be directly clamped on the heat dissipation port, which is suitable for applications with different models or sizes of switches. One end of the positioning clip is equipped with a ring-shaped cable binding unit that can bundle the multiple network cables plugged into the network port expansion switch and organize them on one side of the housing. It will not affect the back of the housing fixed to the inner wall of the weak current box, nor will it be scattered in front of the housing, resulting in large space occupation and inconvenience in finding network cables or power cables.

[0020] The two curved plates of the same ring-shaped cable harness unit can be staggered when storing network cables. After the network cables are placed in the two curved plates, they can be buckled to form a ring structure, which plays a role in limiting and storing multiple network cables.

[0021] Gaskets are provided on the inner sides of the two arc-shaped parts of a ring cable harness unit away from the RJ-45 interface. The gaskets reduce the size of the ring structure formed by the two arc-shaped parts away from the RJ-45 interface, and can clamp multiple network cables on the side of the housing away from the RJ-45 interface, reducing the phenomenon of scattered network cables.

[0022] The length of the positioning clip is 0.5-2cm, which can be adjusted according to the actual space in the weak-current box. It can separate the ring-shaped cable unit from the heat dissipation port so that the bound network cable will not affect the heat dissipation port.

[0023] The two clamping surfaces of the positioning clamp are symmetrically provided with a plurality of clamping protrusions, which facilitates the adjustment of the length of the positioning clamp protruding from the shell. BRIEF DESCRIPTION OF THE DRAWINGS
