Description
Technical Field
The utility model relates to a locking technical field of electronic equipment plug-in components module, concretely relates to novel locking strip device.
Background
At present, electronic devices have been widely used in various aspects of social life, and along with the development of information technology, the electronic devices and functions thereof are more and more complex and diverse. Sometimes these electronic devices, such as avionics, communications electronics, etc., not only need to operate with high reliability in harsh environments, and also, maintenance and repair can be easily performed, so that these electronic devices often adopt a modular design, in a modular design, the electronic device is formed by a plurality of replaceable electronic plug-in modules which are arranged in sequence in the chassis, on the one hand, the plug-in modules need to be firmly connected with the chassis, so that the electronic equipment can work in extreme mechanical environments such as high vibration magnitude and large impact load, on the other hand, the electronic components in the plug-in module can generate heat in work, if the heat cannot be conducted or dissipated in time, the electronic module may overheat or burn out, which may cause the function of the whole electronic device to be abnormal or even fail. In order to meet the requirements of extreme mechanical environment resistance and internal electronic component cooling, wedge-shaped block locking devices are generally installed on two sides of a plug-in module, and after the plug-in module is inserted into a case and matched with a template, the plug-in module is tightly extruded in a channel of the case by the wedge-shaped block locking devices under the action of external force, so that firm connection is formed between the plug-in module and the case, and a conduction path is provided for heat dissipation in the plug-in module.
The existing well-known wedge-shaped block locking device generally comprises a locking guide rail screw rod, a plurality of locking wedge-shaped blocks and a locking nut, wherein the locking wedge-shaped blocks can freely slide along the locking guide rail screw rod, a matched wedge-shaped inclined plane between the locking wedge-shaped blocks forms an angle of 45 degrees with the axis of the locking guide rail screw rod, the locking wedge-shaped blocks are axially pushed to move outwards along the wedge-shaped inclined plane by rotating the locking guide rail screw rod, the height size of the wedge-shaped block locking device is increased until the wedge-shaped blocks are tightly attached to the slot walls at two sides, the plug-in module and the wall surface of a slot channel of a case are extruded, and therefore enough friction force is generated to firmly fix the plug-in module in the. However, although the conventional wedge locking device can fix the plug-in module and provide a heat conduction path, there are still some structural design problems that cause the service performance of the wedge locking device to be degraded, for example, because of the existence of the locking guide rail screw rod in the conventional wedge locking device, the cross section of the locking wedge can only be designed into an open thin-wall structure, so that on one hand, the contact area of the matching wedge inclined planes between different locking wedges is very small, the contact thermal resistance is very large, and the thermal resistance of the whole heat conduction path is increased; on the other hand, the cross section of the open thin-wall structure weakens the capacity of the locking wedge blocks for resisting axial force, the matching parts between the wedge blocks are easy to generate plastic deformation under the action of the axial force, and the wedge block locking device is blocked, so that the plug-in module cannot be pulled out of the case.
The patent No. 201620453171.4 discloses a guide-rail-free low-thermal-resistance locking device, which cancels a locking guide rail screw rod in the existing wedge-shaped block locking device, wherein two sides of a first wedge-shaped block are provided with a guide chute and a cylindrical pin, two sides of a second wedge-shaped block are provided with guide sheets inserted into the guide chute, and the guide sheets are matched with the cylindrical pin to form local sliding connection between the wedge-shaped blocks; secondly, the fixed block in the locking device needs to be fixedly connected to the electronic module, and is used fixedly, so that the locking device is not beneficial to plug and play; thirdly, the locking device is not provided with a reset mechanism after being loosened, when the wedge-shaped block locking device cannot be loosened, the locking wedge-shaped block automatically moves inwards along the wedge-shaped inclined plane to be away from the slot walls at the two sides, and in addition, the slot for installing the wedge-shaped block locking device is narrow, so that the wedge-shaped block locking device is difficult to loosen and take out.
