The embodiments of the present application will be described in detail below with reference to the accompanying drawings by means of specific embodiments and application scenarios thereof.

Referring to fig. 1 to 8, the embodiment of the present application discloses a locking mechanism 100 for limiting and fixing an electrical component 300 in a product assembling process, so as to ensure that the electrical component 300 cannot move randomly in an installation process. Illustratively, the latching mechanism 100 may be applied to an assembly process of a CPU, and in particular, during an installation process of a CPU, the CPU may be restrained on the circuit board 200 by the latching mechanism 100 so as to be installed to the circuit board 200. Of course, the locking mechanism 100 may also be applied to other scenarios, and is not limited in particular. The disclosed locking mechanism 100 includes a cover plate 110, a locking assembly 120, and a locking seat 130.

The locking assembly 120 includes a mounting base 121, a locking member 122, and an elastic member 123, wherein the mounting base 121 is a basic mounting member that can provide a mounting basis for the locking member 122 and the elastic member 123. In some embodiments, the locking member 122 is rotatably connected to the mounting base 121, so as to switch the state of the locking member 122 in a rotating manner; the elastic member 123 elastically connects the locking member 122 and the mounting base 121 so as to maintain the locking member 122 in a locked state under an elastic action. Illustratively, the elastic member 123 may employ a spring, a rubber member, or the like, including, for example: the specific form of the compression spring, the tension spring, the torsion spring, the rubber strip and the like is not limited.

The cover plate 110 is used for limiting the electrical component 300 to be mounted, and the cover plate 110 can cover directly above the electrical component 300 to be mounted and press the top surface of the electrical component 300, so as to prevent the electrical component 300 from moving randomly and facilitate mounting. In some embodiments, the cover 110 may be connected to the mounting base 121, so that when the locking member 122 is in the locked state, the mounting base 121 cannot move, and the cover 110 cannot move, so that a limiting force may be applied to the electrical component 300 by the cover 110, so as to prevent the electrical component 300 from moving randomly during the installation process.

Illustratively, the cover plate 110 may be connected to the mounting base 121 of one locking assembly 120, and may also be connected to the respective mounting bases 121 of a plurality of locking assemblies 120, which may be specifically selected according to the actual working conditions.

In this embodiment, when the locking member 122 and the locking seat 130 are in a locked state, the limiting action on the electrical element 300 can be achieved through the cover plate 110, and when the limiting action on the electrical element 300 needs to be released after the electrical element 300 is installed, the locking member 122 and the locking seat 130 can be released, so that the locking member 122, the installation base 121 and the cover plate 110 can be removed together.

In this embodiment of the present application, the locking seat 130 may be mounted to the circuit board 200, so as to ensure that the locking seat 130 is firmly fixed during the installation of the electrical component 300, in this case, the locking assembly 120 that is in locking fit with the locking seat 130 and the cover plate 110 that is connected with the locking assembly 120 are firmly fixed, so that a limiting force may be applied to the electrical component 300 through the cover plate 110, and it is ensured that the electrical component 300 cannot move at will during the installation.

In order to switch between the locking state and the unlocking state of the locking member 122 and the locking seat 130, the locking member 122 may have a first locking portion 1221, and correspondingly, the locking seat 130 has a second locking portion 131, and the first locking portion 1221 may be in locking engagement with the second locking portion 131. Based on this, in the first state (i.e., in the locked state), the first locking portion 1221 is in locking engagement with the second locking portion 131, so that the locking assembly 120 is locked with the locking seat 130, so that the cover plate 110 connected to the mounting base 121 in the locking assembly 120 can be ensured to be fixed, so that the electrical component 300 is limited by the cover plate 110, and the electrical component 300 is convenient to install; in the second state (i.e., the unlocked state), the first clamping portion 1221 is disengaged from the second clamping portion 131 to unlock the locking assembly 120 from the locking seat 130, so that the locking assembly 120 and the cover plate 110 can be conveniently removed.

The state switching between the first engaging portion 1221 and the second engaging portion 131 can be achieved by rotating the locking member 122 with respect to the mounting base 121. Specifically, in the normal state, the locking assembly 120 is separated from the locking seat 130, and at this time, the locking member 122 is in the locked state under the elastic force of the elastic member 123; when the locking assembly 120 is required to be locked and matched with the locking seat 130, a force can be applied to the locking member 122, so that the locking member 122 can rotate for a certain angle relative to the mounting base 121 against the elastic force of the elastic member 123, and the locking member 122 is switched to an unlocking state; the locking piece 122 is moved to the rear of the first clamping portion 1221 located at the second clamping portion 131, then the acting force applied to the locking piece 122 is released, under the action of the elastic force of the elastic piece 123, the locking piece 122 returns to the locking state, so that the first clamping portion 1221 is clamped and matched with the second clamping portion 131, the locking piece 122 is locked with the locking seat 130, and in this case, the locking assembly 120 and the cover plate 110 cannot move integrally relative to the locking seat 130, and therefore the electric element 300 to be installed can be limited through the cover plate 110, and the installation of the electric element 300 is facilitated.

When the locking assembly 120 and the cover plate 110 need to be removed, an acting force is applied to the locking member 122 again, so that the locking member 122 overcomes the elastic force of the elastic member 123 to rotate relative to the mounting base 121, and the first clamping portion 1221 and the second clamping portion 131 are released from the clamping fit, so that the locking assembly 120 and the cover plate 110 can be separated from the locking seat 130, and further the limiting effect of the cover plate 110 on the electrical component 300 can be released, so that the electrical component 300 can be reused next time.

Based on the above-mentioned setting, the embodiment of the application can limit the electric element 300 to be installed through the locking mechanism 100 to prevent the electric element 300 from moving at will in the installation process and affecting the installation accuracy, meanwhile, two persons are not required to operate simultaneously, only one person is required to operate easily and fix the electric element 300 is realized, and the disassembly and assembly are convenient, therefore, the operation can be convenient, the installation efficiency of the electric element 300 is improved, and the assembly accuracy and the assembly efficiency of products are further improved.
