In this way, the installation guide effect can be achieved as well.

In an alternative solution of this embodiment, the installation guide structure includes a first annular wall 5, and the first annular wall 5 is adapted to be inserted into the housing in cooperation with the housing. So set up, first rampart 5 is located the shell, makes the outside wholeness of shell good, and the structure is pleasing to the eye. However, the first annular wall 5 may be sleeved on the housing, and the first annular wall 5 is located outside the housing to protect the housing and prevent the housing from being damaged.

In an optional technical scheme of the embodiment, at least one convex rib 6 for being attached to the inner wall of the shell is arranged on the outer side wall of the first annular wall 5 along the circumferential direction; the ribs 6 extend in the direction from the first end face 3 to the second end face 4.

In this embodiment, along the direction of first terminal surface 3 to second terminal surface 4, have the clearance between the lateral wall of first rampart 5 and the inside wall of shell, the lateral wall of first rampart 5 passes through protruding muscle 6 and pastes with the inside wall of shell, so, when the installation, protruding muscle 6 is easily by extrusion deformation in the clearance, avoids the installation card to pause. Preferably, the plurality of ribs 6 are provided, so that the stability during installation is improved.

In this embodiment, the end of the rib 6 away from the second end face 4 is provided with a slope along the extending direction, and the slope has a guiding function and is convenient to insert into the housing.

In an optional technical solution of this embodiment, at least one notch 7 is formed at one end of the first annular wall 5 away from the second end face 4. In the installation, the extrusion force of the shell to the first annular wall 5 is buffered through the notch 7, so that the first annular wall 5 can have a certain inward shrinkage space, and the installation blockage is avoided. Preferably, breach 7 is provided with two, and corresponds each other, can further improve the installation smooth and easy degree, easy to assemble.

In an optional technical solution of this embodiment, the welding device further includes an annular ultrasonic welding rod 8, and the ultrasonic welding rod 8 is disposed on the second end face 4 and located outside the first annular wall 5.

In this embodiment, roof 1 passes through the ultrasonic bonding mode with the shell and fixes, at this moment, be provided with the loop platform on the inner wall of shell, the back is accomplished in the inside wall cooperation direction installation of the lateral wall of first rampart 5 and loop platform, ultrasonic bonding electrode 8 offsets with one side of loop platform orientation second terminal surface 4, roof 1 inlays to be established in the assembly opening, and the outer fringe of roof 1 and the inner edge laminating of assembly opening, make ultrasonic bonding electrode 8 melt through the ultrasonic bonding's mode this moment, fix roof 1 on the loop platform, it is fixed firm, and the seal is good.

In this embodiment, the top plate 1 may be fixed to the ring table by other fixing connection methods such as screws, as long as the requirements are met.

In an optional technical scheme of this embodiment, an annular protruding portion may be disposed at an outer edge of the top plate 1, the protruding portion is flush with the second end surface 4, and forms a first annular groove 9 with the ultrasonic welding rod 8, and the ultrasonic welding rod 8 can enter the first annular groove 9 after being melted, so that deformation of the outer shell due to excessive interference after the ultrasonic welding rod 8 is melted is avoided; the inside wall that also can be ultrasonic welding rod 8 sets up with the lateral wall interval of first rampart 5, and is formed with second annular 10, and ultrasonic welding rod 8 melts the back, can get into second annular 10, avoids ultrasonic welding rod 8 to melt the back interference and excessively leads to the shell to warp.

In the preferred embodiment, the first ring groove 9 and the second ring groove 10 are both arranged, so that the melted ultrasonic welding rod 8 can be accommodated in the first ring groove 9 and the second ring groove 10, and the shell is prevented from deforming better.

In an optional technical solution of this embodiment, a first guiding inclined surface 12 is disposed on an outer side wall of the first annular wall 5, and the first guiding inclined surface 12 is located at an end of the first annular wall 5 away from the second end surface 4. The first guide inclined plane 12 is annular and inclines to one side away from the shell from the direction from the first end face 3 to the second end face 4, so that the structure is simple, the first guide inclined plane can be conveniently inserted into the shell and the annular platform, and the clamping is avoided.

In the optional technical scheme of this embodiment, the installation guide structure includes second cliff 11, and second cliff 11 corresponds with interface 2, and is used for cup jointing outside female seat with female seat cooperation. So set up, outside second cliff 11 was located female seat, avoided female seat impaired, convenient simultaneously with female seat cooperation direction, female seat and interface 2 corresponding can be guaranteed throughout to second cliff 11 simultaneously, make external equipment pass interface 2 and get into can be connected with female seat in the second cliff 11 and realize charging, effectively prevent to lead to female seat and interface 2 dislocation under the exogenic action.

In an optional technical solution of this embodiment, a second guiding inclined surface 13 is disposed on an inner side wall of the second annular wall 11, and the second guiding inclined surface 13 is located at an end of the second annular wall 11 far away from the second end surface 4. Wherein, second direction inclined plane 13 is cyclic annular, and by the direction of first terminal surface 3 to second terminal surface 4, to the one side slope towards the shell, so, simple structure makes things convenient for female seat to insert, avoids the card to pause.

In the optional technical solution of this embodiment, the female seat further includes a limiting structure 14, the limiting structure 14 is located in the second annular wall 11 and is used for limiting the female seat from extending out of the second annular wall 11, and the projection is along the direction from the second end surface 4 to the first end surface 3. In the top cap installation, the top cap is installed by the direction of first terminal surface 3 to second terminal surface 4, makes female seat insert in second cliff 11, and limit structure 14's setting can prevent effectively that female seat from inserting too deeply, stretches out even in second cliff 11 gets into interface 2, influences normal use, and female seat damages easily simultaneously.

In an optional technical solution of this embodiment, the limiting structure 14 is annular. So, can restrict female seat in circumference and stretch out, make the spacing effort that female seat received even, spacing stable.

However, the limiting structure 14 is not limited to this, and may be a plurality of protrusions arranged along the circumferential direction, as long as the limiting requirement is met.

In the optional technical solution of this embodiment, the limiting structure 14 may be disposed at any position of the inner side wall of the second annular wall 11, as long as the female socket can be inserted into the second annular wall 11 and does not extend out, preferably, the limiting structure 14 is located at one end of the second annular wall 11 facing the second end face 4. So set up, make female seat can furthest in stretching out second rampart 11, female seat of second rampart 11 protection that can furthest can reduce female seat simultaneously along the occupation space on second terminal surface 4 to the 3 directions of first terminal surface, improve space utilization.

Specifically, along second terminal surface 4 to 3 directions of first terminal surface, have the interval between the inside wall of second rampart 11 and the inside wall of interface 2, make roof 1 be located the part at this interval and form limit structure 14, so, simple structure, the preparation is convenient, practices thrift the cost.
