[0012] After the switch interface and the data cable plug are connected in the connection slot, the switch body is rotated so that the interface rotates from the connection slot to the protection slot. The protection slot clamps the data cable plug into the inner side of the protection shell so that the data cable passes through the protection slot. Even if the data cable is pulled from the outside, the data cable plug will not fall off the interface due to the clamping effect of the protection slot, which protects the connection between the interface and the data cable plug.

[0021] As a further option, the locking structure includes recesses arranged on the upper and lower sides of the connection between the connecting groove and the protective groove, and two elastic clamping plates are symmetrically arranged in the recesses on the upper and lower sides. The opposite side walls of the two elastic clamping plates are concave, and a clamping space for clamping the hand paddle is formed between the concave parts of the two elastic clamping plates.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The industrial switch with interface protection function in the present application mainly protects the switch interface and avoids direct exposure of the connection part between the interface and the data cable plug, thereby enhancing the connection reliability between the two and preventing the connection part from being affected by the external environment.

[0039] See also Figure 1-Figure 7 The industrial switch with interface protection function provided by the present invention comprises:

[0040] The switch body 3 and the protective shell arranged outside the switch body 3; Figure 4 As shown, the switch body 3 and the protective shell are both disc-shaped, the switch body 3 is located inside the protective shell, and the switch body is rotatably installed in the protective shell, that is, the switch body 3 can rotate inside the protective shell.

[0041] By providing a protective shell outside the switch body 3, effective protection for the switch body 3 can be formed. Specifically, the switch body 3 is placed in the protective shell, which includes a lower shell 1 that is hollow and has an upper opening, and a top cover 2 that is detachably connected to the upper end of the lower shell 1. A protective space is formed between the interior of the lower shell 1 and the top cover 2, and the switch body 3 is located in the protective space. At least two connecting screws are provided at the edge of the top cover 2, and connecting screw holes corresponding to the positions of the connecting screws are provided at the upper edge of the lower shell 1. The top cover 2 is connected to the lower shell 1 by the cooperation of the connecting screws and the connecting screw holes, and the lower shell 1 and the top cover 2 can also be connected by a snap connection.

[0042] The switch body 3 includes a hollow upper shell 31 with an opening at the bottom, and a bottom cover 32 detachably connected to the opening at the bottom of the upper shell 31. The upper shell 31 is provided with a switch circuit structure and an interface (not shown in the figure) electrically connected to the switch circuit structure. The outer wall of the upper shell 31 is provided with a mounting groove 34 for clamping the interface. The interface is installed in the mounting groove 34. Figure 6 As shown, the bottom cover 32 is also connected to the lower opening of the upper shell 31 by connecting screws or buckles. The upper shell 31 and the bottom cover 32 form an installation space for installing the switch circuit structure and the interface. The switch circuit structure is placed inside the installation space, and the interface is plugged into the installation slot 34 and fixed to the interface by buckles, or the interface is fixed to the installation slot 34 by bonding, as shown in FIG. Figure 1 As shown, the interface can be exposed in the connecting groove 4 and the protective groove 5.

[0043] A connecting groove 4 and a protective groove 5 are provided on the front wall of the lower shell 1. The connecting groove 4 is connected to one side of the protective groove 5, and the connecting groove 4 and the protective groove 5 are communicated with each other. The longitudinal width of the connecting groove 4 is greater than the longitudinal width of the interface, and the longitudinal width of the protective groove 5 is less than the longitudinal width of the interface. The connecting groove 4 and the protective groove 5 correspond to the positions of the interface.

[0044] By means of the connection groove 4 and the protection groove 5, the data line plug can be connected to the switch interface, and after the connection, by rotating the switch body 3, the connection part between the data line plug and the switch interface and the data line are rotated and moved to the protection groove 5, thereby protecting the connection part between the data line plug and the switch interface.

[0045] like Figure 1 As shown, specifically, when the interface is connected to the data line plug, the interface is rotated to the connection slot 4, where the data line plugs are connected to the interfaces one by one. After the connection, the data line plugs are plugged into the interface, and the switch body 3 is rotated relative to the protective shell so that the interface and the data line plug thereon are rotated into the protective slot 5. Since the longitudinal width of the protective slot 5 is small, the data line plug can be restricted so that the data line plug cannot be pulled out of the protective slot 5. At the same time, the data line body can pass through the protective slot 5, so that the data line can be used normally. Hiding the interface and the data line plug inside the protective shell can play a role in dust and water prevention, and pulling from the outside will not cause the data line plug to detach from the interface.

[0046] Considering the heat dissipation of the whole device, a lower heat dissipation slot 12 is provided on the lower surface of the lower housing 1, and an upper heat dissipation slot 33 corresponding to the position of the lower heat dissipation slot 12 is provided on the bottom cover 32. Through the corresponding arrangement of the lower heat dissipation slot 12 and the upper heat dissipation slot 33, a transparent heat dissipation channel between the switch body 3 and the bottom of the protective housing is formed, so that the heat generated by the switch circuit structure can be directly dissipated downward, reducing the accumulation of hot air at the bottom of the switch host 3 and the protective housing. A support block is provided at the bottom of the lower housing 1 to raise the lower housing 1 as a whole, forming a heat dissipation gap, thereby facilitating the exchange of hot and cold air at the heat dissipation gap position and ensuring the smoothness of heat dissipation.

[0047] Support platforms 35 are provided on both sides of the inner wall of the upper housing 31. The switch circuit structure is supported on the lower side of the support platforms 35, and the support platforms 35 are connected to the switch circuit structure by screws. Figure 6As shown, the support platform 35 is arranged in the middle part of the upper shell 31 to raise the switch circuit structure. After the switch circuit structure is raised, there can be enough heat dissipation gap between the upper and lower surfaces and the top and bottom of the switch body 3. Compared with the installation form of the switch circuit structure fitting closely, the heat dissipation gap provides an effective heat dissipation space, so that the heat dissipation space is in contact with the cold air entering from the outside, which is convenient for heat exchange.

[0048] Preferably, a circle of supporting ridges 13 is provided inside the upper opening of the lower shell 1, and the top cover 2 is supported on the supporting ridges 13. By providing the supporting ridges 13, when the top cover 2 is sunk into the upper opening of the lower shell 1, it can be supported by the supporting ridges 13, and the thickness of the top cover 2 is set to be the same as the depth of the supporting ridges 13, so that the top cover 2 is flush with the upper surface of the lower shell 1 after installation, and is not easy to scratch other objects.

[0049] In order to enable the switch interface to be transferred between the connection slot and the protection slot, the switch body 3 is rotatably installed in the protective shell, and it is convenient to adjust the position of the connection part. Preferably, the switch body 3 and the protective shell are both set to a disc shape, and the lower surface of the switch body 3 is provided with a circular support rail 10, and the bottom of the inner cavity of the lower shell 1 is provided with a support ring 11 corresponding to and matching the position of the circular support rail 10, and the circular support rail 10 is slidably supported on the support ring 11, and the center of the circular support rail 10 and the center of the support ring 11 coincide with the center of the protective shell. The circular support rail 10 is slidably supported on the support ring 11, and when the switch body 3 is rotated relative to the protective shell, the switch body 3 rotates smoothly, avoiding the situation where the switch body 3 is offset during the rotation process.

[0050] Preferably, a rotation adjustment slot 14 is provided in the middle of the upper surface of the top cover 2. By setting the rotation adjustment slot 14, the switch body 3 can be operated to rotate relative to the protective housing by manually touching the switch body 3 from the top, and the switch body 3 can be driven to rotate by the friction between the fingers and the switch body 3 by supporting the switch body 3 with at least two fingers.

[0051] Preferably, an adjustment knob 6 is fixedly mounted in the middle of the upper surface of the switch body 3, and the adjustment knob 6 passes through the rotation adjustment slot 14 and extends to the upper side from the rotation adjustment slot 14. The setting of the adjustment knob 6 facilitates the adjustment and rotation of the switch body 3, and the surface of the adjustment knob 6 is provided with anti-slip stripes.

[0052] By providing the adjusting knob 6 , the switch body 3 can be rotated, and further, by rotating the switch body 3 , the position of the interface can be adjusted between the connecting slot 4 and the protecting slot 5 .

[0053] Preferably, the connection slot 4 is located on the right side of the protection slot 5, and a hand paddle 7 is provided on the front wall of the switch body 3, the hand paddle 7 is located on the right side of the interface, and the hand paddle 7 is located in the through slot formed by the connection slot 4 and the protection slot 5. By providing the hand paddle 7, the switch body 3 can also be adjusted and rotated, and here, the hand paddle 7 has the same function as the adjustment knob 6, which is to facilitate the rotation of the switch body 3.

[0054] By respectively providing the adjustment knob 6 , the rotation adjustment slot 14 and the hand paddle 7 , the switch body 3 can be rotated from the top and the side, respectively, thereby enhancing the flexibility of adjusting the interface position.

[0055] Preferably, a locking structure is provided at the connection of the connection slot 4 and the protection slot 5, and the hand paddle 7 moves to the locking structure, and the locking structure is connected to the hand paddle 7 to lock the switch body 3. Through the setting of the locking structure, when the interface is rotated into the protection slot 5, the locking structure is connected to the hand paddle 7, and when in use, the switch body 3 is prevented from rotating relative to the protective housing.

[0056] Preferably, the locking structure includes recesses 8 provided at the upper and lower sides of the connection between the connecting groove 4 and the protective groove 5, and two elastic clamping plates 9 are symmetrically provided in the recesses 8 at the upper and lower sides, and the opposite side walls of the two elastic clamping plates 9 are recessed back to back, so that a clamping space for clamping the hand pick 7 is formed between the recesses of the two elastic clamping plates 9. Figure 7 As shown, the hand paddle 7 enters the card-in space between the two elastic card plates 9 from the right side of the two side elastic card plates 9 to open the two elastic card plates 9. After the hand paddle 7 is carded into the card-in space, the two elastic card plates 9 are reset to clamp the hand paddle 7.

[0057] During use, the interface is rotated in advance at the connecting slot 4, and the data line plugs are plugged into the corresponding interfaces one by one. The switch body 3 is rotated at the top by adjusting the knob 6 or rotating the adjusting slot 14, or the switch body 3 is rotated at the side of the switch body 3 by turning the hand paddle 7, so that the interface is transferred into the protective slot 5, the data line plug is inserted into the inner side of the protective slot 5, and the data line body extends from the protective slot 5 to the outside, so that the data line plug is confined between the protective slot 5 and the interface.

[0058] At the same time, the hand paddle 7 is clamped between the two elastic clamping plates 9. When the external force is small, the hand paddle 7 will not be separated from the clamping space, so that the protective shell and the switch body 3 will not rotate relative to each other.

[0059] The heat generated by the switch circuit structure is dissipated downward from the upper heat dissipation slot 33 and the lower heat dissipation slot 12, protecting the switch circuit structure from the influence of high temperature and allowing the overall switch to operate normally.
