Referring to fig. 1 to 4, the present application provides a signal protection cover, which includes a top base 1, a housing 2 and a base 3; the shell 2 is cylindrical, and the top seat 1 and the base 3 are respectively sealed and arranged at two axial ends of the shell 2; in the signal protection cover, an elastic press button 4 is arranged outside a shell 2, a press button installation part is arranged in a base 3, the elastic press button 4 comprises a root 41 and a head 42, the root 41 of the elastic press button 4 is connected with the shell 2, the head 42 of the elastic press button 4 expands outwards towards the periphery of the shell 2, and a part of the elastic press button 4 close to the root 41 can be extruded and inserted into the press button installation part; in the signal protection cover, a first gasket 5 is arranged between a shell 2 and a base 3, the first gasket 5 and the shell 2 are sequentially sleeved from outside to inside, and the peripheral side surface of the first gasket 5 is provided with a fold surface which can be extruded by interference with a corresponding contact surface.

In this embodiment, the top seat 1, the housing 2 and the base 3 are sequentially connected, and when the base 3 and the housing 2 are sleeved with each other, positioning connection can be achieved through the elastic press buckle 4 and the press buckle mounting portion, in other words, when the base 3 and the housing 2 are sleeved with each other, part of the elastic press buckle 4 of the housing 2 is extruded and inserted into the press buckle mounting portion of the base 3, so that interference fit is achieved between the base 3 and the housing 2. The elastic pressing buckle 4 can be regarded as a hanging lug arranged at two sides of the shell 2, and for the elastic pressing buckle 4, the root 41 is connected with the shell 2, the head 42 is separated from the shell 2 and expands outwards relative to the shell 2, and an operator can easily and conveniently press the head 42 of the elastic pressing buckle 4. When the head 42 of the elastic press button 4 is pressed, the root 41 of the elastic press button 4 is deformed, for example, when the head 42 of the elastic press button 4 is pressed toward the housing 2, the root 41 of the elastic press button 4 is also close to the housing 2, which is beneficial for inserting the root 41 of the elastic press button 4 into the press button mounting portion, and is beneficial for extracting the root 41 of the elastic press button 4 from the press button mounting portion, and when the pressing force applied to the head 42 of the elastic press button 4 is released, the elastic press button 4 is reset under its own elasticity. It can be seen that the elastic press button 4 and the press button mounting portion are advantageous for improving the assembling and disassembling characteristics of the housing 2 and the base 3.

The peripheral surface of the first gasket 5 is provided with a corrugated surface capable of being pressed by interference with a corresponding contact surface, the corrugated surface may be provided on an inner ring of the first gasket 5 or on an outer ring of the first gasket 5, and the inner ring and the outer ring of the first gasket 5 may be provided with corrugated surfaces respectively. The fold surface can improve the interference degree of the first gasket 5 between the shell 2 and the base 3, can accumulate accumulated dust by utilizing the groove formed by the fold surface, and effectively brings out water and dust accumulated in the groove when the first gasket 5 is removed, so that the shell 2 and the base 3 are prevented from being polluted.

Although the installation difficulty can be increased by installing the above-mentioned first gasket 5 between the housing 2 and the base 3 compared with the conventional gasket, the installation and disassembly of the housing 2 and the base 3 can be simplified due to the elastic press buckle 4 and the press buckle installation part, so that the signal protection cover provided by the application can be given consideration to both the waterproof and dustproof performances and the installation performances, in other words, the signal protection cover can play a good waterproof and dustproof role for the electric parts installed therein, and the installation and disassembly of the signal protection cover and the related electric parts can be easily and rapidly realized.

The signal protection cover provided by the application is further described below with reference to the accompanying drawings and embodiments.

When the elastic press button 4 and the press button mounting part are assembled, an operator presses the head 42 of the elastic press button 4 towards the shell 2, so that the head 42 and the root 41 of the elastic press button 4 are both close to the shell 2, and then the root 41 of the elastic press button 4 is extruded and plugged into the press button mounting part. When the root 41 of the elastic press buckle 4 is gradually inserted into the press buckle installation part, the positioning protrusion 6 is continuously close to the positioning groove, the transition cambered surface 62 is close to the root 41, the first limiting plane 61 is close to the head 42, and in the operation process, the transition cambered surface 62 enters the press buckle installation part earlier than the first limiting plane 61, so that the positioning protrusion 6 and the press buckle installation part can be guided to be installed, and the insertion and extraction of the shell 2 in the base 3 are smoother. Once the elastic press buckle 4 and the positioning bulge 6 thereof are inserted into the press buckle installation part in place, the positioning bulge 6 is embedded into the positioning groove, the first limiting plane 61 of the positioning bulge 6 and the second limiting plane of the positioning groove are attached to each other, the elastic press buckle 4 can be prevented from being continuously inserted into the press buckle installation part, and the limiting and locking effects are achieved on the elastic press buckle 4 and the press buckle installation part.
