This utility model discloses a locking component and connector for locking mating connectors, including a base, a connecting arm, an actuating protrusion, and a latching arm. The base has a boss on its top side, a guide rib on its bottom side, latching points on both sides, and a push button on its rear side. The connecting arm extends forward from the left and right sides of the base and connects through the latching arm. The bottom side of the cantilever on the connector housing has a latching groove and a clearance notch, and the bottom side also has a clearance groove communicating with the clearance notch. The actuating protrusion is formed on the top side of the connecting arm and can move between the clearance notch and the clearance groove. The base can switch between a pre-installed state and a locked state. In pre-installation, the latching points engage with the pre-installed latching holes on the connector housing, and the latching arm locks the cantilever. During insertion, the mating connector actuates the actuating protrusion to release the pre-installed state. This locking component provides stable pre-installation, convenient connector assembly, and reliable connection.

The utility model discloses an installation structure of arc extinguishing magnetic steel and relay relates to relay technical field. The relay includes base, dynamic / static contact subassembly, arc extinguishing magnetic steel and shell. The core improvement lies at: the contact receiving cavity of base is equipped with the arc extinguishing magnetic steel installation slot of opening to the side, and the arc extinguishing magnetic steel directly inserts into the slot, and the relative position of contact subassembly is set through single base integration, the sidewall of arc extinguishing magnetic steel installation slot is higher than arc extinguishing magnetic steel to enhance the insulation performance between contacts, and the inside of shell is equipped with blocking rib and limits magnetic steel to come out. Simplify the assembly process, improve structural stability and space utilization, and be applicable to automation production.

The application is suitable for the field of automobile accessories, and provides a protective sleeve for the protection of a display screen. The display screen is vertically placed. The protective sleeve comprises a protective film and a frame wrapped around the lateral side of the protective film. The frame is enclosed to form a fixing cavity for placing the display screen. An avoiding hole is arranged on the part of the frame connected with the lower edge of the protective film, so that the display screen can pass through the avoiding hole to enter the fixing cavity. The protective sleeve provided by the application can meet the protection requirements of the vehicle-mounted display screen, and has simple structure and convenient assembly.

The utility model relates to an atomization device. The atomization device comprises a first supporting structure, a second supporting structure and an elastic sealing piece. Wherein the first supporting structure is provided with a first airflow channel and a first connecting part, and a first airflow cavity is formed in the first airflow channel. The second supporting structure is provided with a second connecting part matched with the first connecting part, and the second connecting part is detachably connected with the first connecting part in a buckled mode. A third airflow cavity is formed in the elastic sealing piece, and the elastic sealing piece is embedded in the second supporting structure. When the first connecting part and the second connecting part are detachably connected in a buckled mode, the bottom of the first airflow channel abuts against the side, close to the first supporting structure, of the elastic sealing piece, and the first airflow cavity communicates with the third airflow cavity. The connecting portion of the first airflow channel and the elastic sealing piece seals the connecting position of the first airflow cavity and the third airflow cavity. The problem that in the prior art, the elastic sealing piece and the first installation support are not easy to assemble is solved.
