[0025] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0026] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations such as "include" or "comprising", etc., will be understood to include the stated elements or components but not to exclude other elements or other components.

[0027] like Figures 1 to 4 As shown, an embodiment of the present invention provides a connecting device for installing a connector set and switching the connector set between a connected position, a test position, and a disconnected position. The connecting device includes a first connecting component 10 and a second connecting component 20.

[0028] The first connecting assembly 10 includes a first fixing portion 11. In one embodiment, the first fixing portion 11 may be an elastomeric structure. Screw holes are provided in the first fixing portion 11, allowing it to be mounted to the drawer-type electrical cabinet, for example, using screws 12. Two symmetrical unlocking arms 13 are provided on one surface of the first fixing portion 11. Each unlocking arm 13 has a raised unlocking contact 131, facing in opposite directions. The unlocking contacts 131 are each formed with an inclined first guide surface 1311 at either end of the first connecting assembly 10 and the second connecting assembly 20, giving the unlocking contacts 131 a certain curvature. The unlocking arms 13 can unlock the second connecting assembly 20 via the unlocking contacts 131. A through-hole 14 is provided on the outer side of the two unlocking arms 13 (near the edge of the first fixing portion 11). The through-hole 14 is configured to accommodate a portion of the components of the second connecting assembly 20. A first mounting portion 15 for mounting the first connector of the connector assembly is provided between the two unlocking arms 13. The first mounting portion 15 is provided with a buckle 151 for locking the first connector. In order to maintain the stability of the first connector installed in the first mounting portion 15, both unlocking cantilevers 13 are provided with abutting portions 132 protruding along the direction of the first mounting portion 15. When the first connector is installed in the first mounting portion 15, the abutting portions 132 on the upper and lower unlocking cantilevers 13 both abut on the first connector, maintaining its stability on the first fixing portion 11 and preventing shaking. Anti-detachment buckles 16 are extended on both sides of each unlocking cantilever 13 on the first fixing portion 11. The anti-detachment buckles 16 can cooperate with some components on the second connector group 20. Their function is to prevent the connector group from detaching when the first connecting component 10 and the second connecting component 20 are plugged in and when the drawer is pulled to the test position (after being installed on a drawer-type electrical cabinet) due to vibration.

[0029] In one embodiment, a protrusion structure or a groove structure is provided on one of the anti-dropout bayonet 16, and correspondingly, a groove or a protrusion structure is provided at a corresponding position on the main body 22 (a component in the second connecting component 20, please refer to the following for detailed description) to achieve anti-misalignment between the two connecting components.

[0030] Since the opening of the screw hole on the first fixing part 11 is relatively large, when the first fixing part 11 is installed on the drawer-type electrical cabinet, there will be a certain degree of floating, which is not conducive to its plug-in connection with the second connecting component 20. Therefore, a first guide member 17 is provided on the first fixing part 11 to guide its plug-in connection with the second connecting component 20.

[0031] The second connecting assembly 20 includes a second fixing portion 21 and a body portion 22 mounted on the second fixing portion 21. Specifically, the second fixing portion 21 is integrally constructed as a shell structure, and the body portion 22 is built into the shell structure and can slide relative to the shell structure under certain conditions.

[0032] like Figure 5 As shown, the second fixing portion 21 is also provided with screw holes, and can be installed on the cabinet body of the drawer-type electrical cabinet, for example, by means of screws 12. Extending from the second fixing portion 21 are two locking cantilevers 211 arranged opposite to each other and adapted to the unlocking cantilever 13 on the first fixing portion 11. Both locking cantilevers 2111 are formed with protruding locking contacts 2111 facing each other, and locking points 2112 are formed on the locking cantilevers 2111 on both sides of the locking contacts 2111. The locking contacts 2111 are formed with inclined second guide surfaces 21111 at both ends of the locking contacts 2111 in the plugging direction of the second connecting component 20 and the first connecting component 10. The second guide surface 21111 can cooperate with the first guide surface 1311 on the unlocking contact 131 to jointly guide the unlocking between the second fixing portion 21 and the main body 22.

[0033] like Figure 6 As shown, a slide groove 221 for accommodating the lock contact 2111 and a snap hole 222 for engaging with the lock clamping point 2112 are formed on the main body 22. One end of the slide groove 221 is open, and the snap holes 222 are provided on both sides of the slide groove 221 along the length direction. The main body 22 is relatively stationary with the second fixed part 21 by the lock contact 2111 and the lock clamping point 2112 on the second fixed part 21 respectively engaging in the slide groove 221 and the snap hole 222 on the main body 22. In a specific embodiment, the lock contact 2111 is formed with a supporting surface 21112 (such as Figure 3 (as shown), the abutting surface 21112 can move the main body 22 along with the second fixing portion 21 after the second fixing portion 21 and the main body 22 remain in this relative static state, and further pulling on the second fixing portion 21 can cause the second connecting assembly 20 to detach from the first connecting assembly 10. The main body 22 has guide portions 223 formed on either side of the slide slot 221. The guide portions 223 are recessed relative to the upper surface of the main body 22 and have third guide surfaces 2231 that slope downward toward the open end of the slide slot 221. The locking point 2112 has a fourth guide surface 21121 that mates with the third guide surface 2231. The main body 22 is also provided with a second mounting portion 224 for mounting the second connector of the connector assembly. The second mounting portion 224 is provided with a latch for locking the second connector.

[0034] Similarly, since the opening of the screw hole on the second fixing portion 21 is relatively large, when the second fixing portion 21 is installed on the drawer-type electrical cabinet, a certain degree of floating will occur, which is not conducive to its plug-in connection with the first connecting component 10. Therefore, a second guide member 225 for guiding its plug-in connection with the first connecting component 10 is provided on the main body 22 arranged in the second fixing portion 21. The second guide member 225 cooperates with the first guide member 17 to guide the connection between the second connector installed on the main body 22 and the first connector installed on the first connecting component 10. In a specific embodiment, the first guide member 17 can be a guide column, and the second guide member 225 can be a guide sleeve. In other embodiments, the second guide member 225 can also be provided on the first fixing portion 11, and similarly, the first guide member 17 can also be provided on the main body 22. In short, as long as the first guide member and the second guide member can guide the movement of the first connecting component 10 relative to the second connecting component 20, it will be sufficient.

[0035] In which, when the connector group is installed in the connecting device and the connector group is in the disconnected position, the first connecting component 10 is separated from the second connecting component 20, and the main body 22 is respectively engaged with the slide groove 221 and the snap hole 222 on the main body 22 by the locking contact 2111 and the locking point 2112 on the second fixed part 21, and is relatively stationary with the second fixed part 21, so that the second connecting component 20 moves as a whole in this relatively stationary state.

[0036] When the connector group switches from the disconnected position to the test position, the first connector and the second connector are plugged in under the action of the first guide member 17 and the second guide member 225, so that the first connecting component 10 is connected to the main body 22, and the unlocking cantilever 13 is inserted into the slide groove 221 from the open end of the slide groove 211, and at the same time, the anti-disengagement buckle 16 is engaged in the buckle hole 222.

[0037] When the connector assembly switches from the test position to the connection position, the unlocking arm 13 continues to move deeper into the slide groove 221, and the unlocking contact 131 on the unlocking arm 13 contacts and lifts the locking contact 2111 on the locking arm 211. At the same time, the locking latch 2112 disengages the latch hole 222, thereby unlocking the main body 22 from the second fixing portion 21, allowing the first fixing portion 11 and the main body 22 to move relative to the second fixing portion 21. The locking arm 211 extends into the through hole 14 of the first fixing portion 11.

[0038] When the connector group is installed in the connecting device and is in the connected position, the first connecting component 10 is connected to the connector in the second connecting component 20, and the locking cantilever 211 extending from the second fixing part 21 extends into the through hole 14 set in the first fixing part 11.

[0039] When the connector group switches from the connection position to the test position, the second fixing portion 21 of the second connecting component 20 moves relative to the first connecting component 10 and the main body portion 22 of the second connecting component 20. During the movement, the raised unlocking contact 131 formed on the unlocking cantilever 13 of the first fixing portion 11 pushes up the locking cantilever 211 of the second fixing portion 21, and the locking contact 2111 and the locking card point 2112 on the second fixing portion 21 will be easily engaged with the slide groove 221 and the locking hole 222 on the main body portion 22 respectively. During this process, the main body portion 22 of the second connecting component 20 is always in an engaged state with the first fixing portion 11 due to the action of the anti-disengagement buckle 16 of the first fixing portion 11, thereby ensuring the stable connection of the communication module or weak current.

[0040] When the connector group switches from the test position to the disconnect position, the second fixing portion 21 further moves away from the first fixing portion 11 until the locking contact 2111 of the second fixing portion 21 abuts against the abutting surface 21112 of the slide groove of the main body portion 22 to abut against the main body portion 22, so that the anti-disengagement bayonet 16 is disengaged from the bayonet hole 222, and the second fixing portion 21 is separated from the first connecting component 10 together with the main body portion 22, thereby realizing the disconnection of the connector group.

[0041] An embodiment of the present invention further provides a drawer-type electrical cabinet, comprising any of the above-described connecting devices, wherein the first fixing portion 11 is mounted on a cabinet panel of the drawer-type electrical cabinet, and the second fixing portion 21 is mounted on a drawer cabinet panel of the drawer-type electrical cabinet.

[0042] The following takes this embodiment as an example to briefly describe the installation and use method or principle of the connecting device of the present invention.

[0043] The first connector is installed in the first mounting portion 15 of the first fixing portion 11 and is locked by the buckle 151 in the first mounting portion 15. The unlocking cantilever 13 can be used to cooperate to maintain the stability of the first connector and prevent it from shaking. On the other hand, the unlocking cantilever 13 can also unlock the second fixing portion 21 in the second connecting component 20 by unlocking the contact 131. The function of the anti-disengagement buckle 16 is to prevent the connector group from being disengaged due to vibration or when the drawer is pulled to the test position after the connector group is plugged in. The floating screw 12 fixes the first fixing portion 11 to the panel of the drawer-type electrical cabinet. However, due to the relatively large opening of the first fixing portion 11, the first fixing portion 11 will float to a certain extent. When the connector group is plugged in, it can be guided by the first guide member 17.

[0044] The second connector is installed into the second mounting portion 224 of the main body 22 and locked by the latch of the second mounting portion 224. Finally, the second fixing portion 21 is put on, and the second connecting assembly 20 is assembled. The locking arm 211 extends into the slide groove 211 through the locking contact 2111, and the locking point 2112 extends into the bayonet hole 222, so that the second fixing portion 21 and the main body 22 are locked to each other. When the second connector is inserted into the first connector, the unlocking contact 131 on the first fixing portion 11 pushes away the locking contact 2111. Since the locking contact 2111 and the locking point 2112 are both connected to the locking arm 211, the locking point 2112 will disengage from the bayonet hole 222, achieving unlocking. At this time, the second fixing portion 21 can move relative to the main body 22.

[0045] Compared with the prior art, the connection device of the embodiment of the present invention can meet the three-position requirements of the connection position, the test position and the disconnection position, and has the advantages of ingenious and compact structure, convenient operation and reliability.
