Fig. 3 is a cross-sectional view of an adapter box provided in an embodiment of the present application. As shown in fig. 2 and 3, the adapter 200 further includes: a housing 203 and a cover plate 209.

The shape and material of the housing 203 and the cover plate 209 are not limited in the embodiments of the present application. Illustratively, the housing 203 is in the shape of a hollow tube, which may have a circular, square, or other irregular shape in axial cross-section.

The housing 203 is made of metal, such as aluminum. Compared with the plastic material, the shell 203 made of the metal material has higher strength, better shock resistance and smaller thickness, and is beneficial to lightening the junction box 200.

And the shell 203 can be integrally formed by adopting an extrusion forming process, so that the strength is higher and the process is simpler. Compared with the injection molding process, the shell 203 does not need to be divided into an upper shell and a lower shell for injection molding respectively, the demolding process is omitted, the number of detached parts is reduced, meanwhile, detachment lines are prevented from being left on the surface of the shell 203 when the upper shell and the lower shell are fixed, and the attractiveness is better.

The cover plate 209 and the housing 203 can be enclosed into a cavity, and the cavity is internally provided with: a PCB soft board 204, a support component 205 and a PCB hard board 207. The flexible PCB 204 is electrically connected to the rigid PCB 207, and the supporting member 205 is used for supporting the flexible PCB 204. From this, the cavity that the shell and apron enclose into can completely cut off interior assembly and external environment, avoids in external impurity invasion cavity, can protect the interior assembly who sets up in the cavity not influenced by external environment.

The chips in the adapter box 200 shown in table 1 may be disposed on a PCB board 207, for example. The HDMI, USB interface, and headphone interface are respectively provided on the cover plates 209 at both ends of the housing 203, and are electrically connected to the PCB board 207, respectively.

For example, a first elastic pad 206 is disposed between the PCB board 207 and the supporting member 205, and a second elastic pad 208 is disposed between the PCB board 207 and the housing 203. Therefore, the first elastic pad and the second elastic pad can fill gaps among the internal components, so that chips arranged on the PCB hard board 207 can be protected, and the shock resistance of the junction box 200 is enhanced.

The PCB flex board 204 includes, for example, opposing first and second surfaces. Wherein a first surface of the PCB 204 is adjacent to the housing 203, and a second surface of the PCB 204 is adjacent to the supporting member 204.

The first surface of the PCB 204 is provided with a switch 2041, for example, and the position of the housing 203 opposite to the switch 2041 is provided with a button 201, for example.

The button 201 is slidably connected to the housing 203, and the button 201 is configured to approach the switch 2041 when receiving a first pressure and return to an initial position after the first pressure disappears. The first pressure may be, for example, a pressing force applied by a user.

The embodiment of the present application does not limit the specific functions of the key 201, and for example, the key 201 includes but is not limited to: a confirmation key, a return key, and a volume key.

The embodiment of the present application does not limit the structure of the key 201 and the assembling manner of the key 201 and the housing 201. In one implementation of the present application, the key 201 is made of metal, for example. One end of the key 201 close to the switch 2041 is provided with a limiting part, for example, and the limiting part is located inside the housing 203, so that the movement of the key 201 can be limited between the housing 203 and the switch 2041, and the key 201 is prevented from being separated from the housing 203.

For example, as shown in fig. 3, the limiting portion may be, for example, a silicone pad 202, the silicone pad 202 includes, for example, a first surface and a second surface that are opposite to each other, one end of the button 201 close to the switch 2041 is connected to the first surface of the silicone pad 202, and the second surface of the silicone pad 202 is disposed close to the switch 2041.

The key 201 is, for example, a groove structure, and a convex portion matched with the groove structure is arranged on the first surface of the silica gel pad 202. When the key 201 and the silicone pad 202 are assembled, the convex portion of the silicone pad 202 may be snapped into the concave groove of the key 201. The key 201 and the silicone pad 202 may be further fixed and connected together by means of dispensing or adhesive-backed bonding.

And the position of the silica gel pad 202 opposite to the switch 2041 is provided with a protrusion 2021, and the protrusions 2021 correspond to the switches 2041 one by one. When the button 201 is pressed, the pressing force can be transmitted to the silicone pad 202, and then transmitted to the switch 2041 through the protrusion 2021 disposed on the silicone pad 202. From this, adopt silica gel pad 202 as spacing portion, press the better feel.

The material of spacing portion is not limited to above-mentioned silica gel pad 202, if spacing portion adopts the material that other elasticity are relatively poor, can also set up elastomeric element between switch 2041 and spacing portion, elastomeric element for example can adopt the material that resilience performance is better such as silica gel pad, silica gel cover. In addition, the position of the elastic component opposite to the switch can be provided with a bulge, and the bulges are in one-to-one correspondence with the switch.

When the adaptor box 200 is assembled, the first end of the housing 203 is open, and the second end is provided with the cover plate 209, so that the internal components can extend into the housing 203 through the first end and be fixedly connected with the housing 203. After the internal components are fully assembled, a cover plate 209 may be provided at the first end of the housing 203.

The plurality of keys 201 are fixedly connected with the silica gel pad 202, and the keys 201 can be assembled on the housing 203 from the inner side to the outer side of the housing 203.

Fig. 4 is a flowchart of an assembly method of an adapter according to an embodiment of the present disclosure. As shown in fig. 4, the method includes:

s101, assembling a key module consisting of a silica gel pad, a PCB soft board provided with a switch and a supporting part on the shell.

For example, as shown in fig. 4a, in the process of assembling the key 201 in the housing 203, the key 201 may be fixedly connected to the silicone pad 202. Next, the silicone pad 202 and the PCB 204 with the switch 2041 may be assembled on the supporting member 205 to serve as a key module, and then the key module is inserted into the housing 203, where the housing 203 is provided with a through hole 2031 matching the shape of the key 201, for example, the key 201 and the through hole 2031 may be assembled in a one-to-one alignment manner, and then the key module and the housing 203 may be fixedly connected together by dispensing.

S102, assembling the PCB hard board, the first elastic cushion and the second elastic cushion in the shell.

As shown in fig. 4b, after the assembly of the key 201 is completed, the PCB board 207, the first elastic pad 206 and the second elastic pad 208 may be fixedly connected together by bolts or by dispensing, etc. to form a PCB assembly, and then the PCB assembly extends into the housing 203 and is fixedly connected to the housing 203.

And S103, assembling the cover plate on the shell.

As shown in fig. 4c, the cover plate 209 may be assembled to the first end of the housing 203, so as to complete the assembly of the adaptor box 200.

Of course, when the key 201 is assembled in the housing 203, the silicone pad 202 provided with the key 201 may be directly inserted into the housing 203, and the key 201 and the through hole 2031 provided in the housing 203 may be assembled in one-to-one alignment. And other internal components are assembled in the housing 203.

However, in the above embodiment, the stopper portion of the key is provided inside the housing, and when the key is assembled, the key can only be assembled from the inside of the housing 203 to the outside, which is difficult to operate. Moreover, a plurality of keys 201 need to be assembled together, which increases the chain length of the keys 201 and reduces the pressing feeling of the keys 201.

In another implementation of the present application, the limiting portion may be, for example, a snap assembly. The snap assembly includes, for example: a clamping protrusion and a clamping groove. The clamping groove can be arranged on the key, and the clamping protrusion is arranged in the through hole of the shell. Or a clamping groove can be arranged in the through hole of the shell, and the clamping protrusion is arranged on the key.

The clamping protrusion is positioned in the clamping groove, and when the key moves relative to the switch, the clamping groove moves relative to the clamping protrusion. Therefore, the clamping protrusion can limit the movement of the clamping groove, so that the movement of the key is limited, and the key is prevented from being separated from the shell.

Illustratively, as shown in fig. 5a, 5b, and 5c, as shown in fig. 5a, the card slot 2012 is disposed on the key, and the card protrusion 2032 is disposed inside the through hole 2031 of the housing 203.

The button 201 is, for example, a solid structure. The key 201 may be made of metal or plastic. The end of the key 201 facing away from the switch 2041 is provided with a key cap 2011, for example. The key cap 2011 is provided with an elastic hook having an L-shaped structure, and the elastic hook and the key cap 2011 form a slot 2012 with an opening on the side.

The elastic clamping hook can be made of elastic materials such as silica gel, and therefore when the key 201 is assembled, the elastic clamping hook can be elastically deformed so that the clamping protrusion can be clamped into the clamping groove, assembly can be conducted inwards from the outer side of the shell 203, and the assembly mode is simpler. Meanwhile, a plurality of keys 201 do not need to be assembled together, the chain length of the size of the keys 201 is reduced, and the pressing hand feeling of the keys 201 is improved.

The housing 203 is provided with a through hole 2031, and the clamping protrusion 2032 is arranged on the inner side wall of the through hole 2031 and extends into a clamping groove formed by the clamping groove 2012 and the key cap 2011.

When the button 201 is close to or far from the switch 2041, the key cap 2011 moves along with the button 201, and drives the card slot to move up and down in the through hole 2031. The protrusion 2032 can limit the movement of the card slot in the through hole 2031 of the housing 203 to prevent the button 201 from falling out of the housing 203.

The key cap 2011 is further provided with, for example, a support rib 2013, and the support rib 2013 is provided around the key 201, for example, to prevent the key 201 from shifting the pressed position.

For example, an elastic part is further arranged between the key and the switch, the resilience performance of the key can be better through the arrangement of the elastic part, and the pressing hand feeling is improved. For example, the elastic component may be, for example, a silicone cover 2020, the silicone cover 2020 may be disposed on the PCB 204, the switch 2041 is located in an area surrounded by the silicone cover 2020 and the PCB 204, a protrusion 2021 is disposed on one side of the silicone cover 2020 near the switch 2041, and the protrusion 2021 corresponds to the switch 2041 one to one.

When the key 201 is pressed, the pressing force can be transmitted to the silicone cover 2020, and then transmitted to the switch 2041 through the protrusion 2021 provided on the silicone cover 2020. Therefore, the switch 2041 is provided with the silicone cover 2020, which provides a better pressing feeling.

When the adaptor box 200 is assembled, the internal components may be assembled in the housing 203 first, and then the key 201 is mounted on the housing 203, or the key 201 may be mounted on the housing 203 first, and then the internal components may be assembled in the housing 203. The assembly manner of the housing 203 and the cover plate 209 can refer to the above embodiments, and is not described herein again.

Fig. 5 is a flowchart of another method for assembling an adapter according to an embodiment of the present disclosure. As shown in fig. 5, the method includes:

s201, assembling a key module consisting of the key, the keycap, the clamping groove and the supporting rib on the shell.
