Abstract
The utility model discloses a locking mechanism for a crate plug-in unit. In the locking mechanism for the crate plug-in unit, a printed board plug is arranged at the front end of the crate plug-in unit, the upper part and the lower part of the back end of the crate plug-in are respectively provided with a locking device which comprises a locking hook, a reset pressure spring and a handle, wherein the locking hook is fixed on a locking shaft, the reset pressure spring is sleeved above the locking shaft, the handle is connected with the crate plug-in unit by a rotary shaft, and one end of the handle is adjacent to the downside of the locking shaft. Compared with a crate plug-in unit fixed with screws, the locking mechanism of the crate plug-in unit is more convenient to plug, has more reliable electric performance and saves the time. Due to that panel screws are not used, the left part and the right part of the plug-in unit are not limited by the panel screws, thereby poor contact of the plug and a socket is avoided, and the contact reliability of the plug and the socket is improved.
Description
Technical field
The utility model relates to cabinet plug-in unit field of fixation devices, more particularly, relates to a kind of locking mechanism of cabinet plug-in unit.
Background technology
Printed-board receptacle is set in the cabinet, and cabinet plug-in unit one end is provided with edge connector, and the cabinet plug-in unit inserts along guide rail in the cabinet edge connector is contacted with socket.Existing structure be when edge connector with cabinet plug-in unit and cabinet are carried out after socket contacts fasteningly, fastening means can not guarantee that edge connector reliably contacts with socket like this, has the phenomenon that moves mutually.And this fastening means also is not easy to dismounting and changes.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of locking mechanism of cabinet plug-in unit is provided.
The locking mechanism of the utility model cabinet plug-in unit, be achieved by following technical proposals, cabinet plug-in unit front end is provided with edge connector, it is characterized in that the upper and lower of described cabinet plug-in unit rear end is provided with locking device respectively, described locking device comprises latch hook, reseting pressuring spring and handle, latch hook is fixed in lock shaft, the lock shaft top is with reseting pressuring spring, and handle is connected in the cabinet plug-in unit by rotating shaft, and handle one end is adjacent with the lock shaft below.
The utility model is compared with screw cabinet plug-in unit, plugs more conveniently, and electric property is more reliable, saves time.Owing to, be not subjected to the constraint of panel screw about plug-in unit without panel screw, avoided the plug and socket loose contact, improved the contact reliability of plug and socket.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model locking device lock-out state schematic diagram;
Fig. 3 is the utility model locking device view that unlocks.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, cabinet plug-in unit front end is provided with edge connector 1, the upper and lower of described cabinet plug-in unit rear end is provided with locking device 2 respectively, as shown in Figure 2, described locking device comprises latch hook 3, reseting pressuring spring 4 and handle 5, and latch hook is fixed in lock shaft 6, and the lock shaft top is with reseting pressuring spring, handle is connected in the cabinet plug-in unit by rotating shaft 7, and handle one end is adjacent with the lock shaft below.
Insertion process of the present utility model: when plug-in unit slides into the latch hook interface in the cabinet guide rail, latch hook moves upward to cabinet guide rail horizontal plane, latch hook continues to front slide on cabinet guide rail horizontal plane, and latch hook comes downwards to the concave station place pinning plug-in unit that slides downwards in the effect of stage clip, as shown in Figure 2.At this moment edge connector reliably contacts with socket, and plug-in unit is by firm pinning.The cabinet plug-in unit is transferred to process: during pull handle, handle rotates around the shaft, promotes latch hook and overcomes stage clip power disengaging cabinet, as shown in Figure 3, extracts plug-in unit.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in this area various distortion and improvement all should belong to protection range of the present utility model.
