[0002] With the continuous development of electronic technology, the technology for connecting external camera modules to portable terminal devices such as mobile phones has become increasingly mature. Mobile phones can meet more professional shooting needs by connecting higher-performance external camera modules.
[0003] For mobile phones with external connectivity, there are several contacts on the back panel of the phone and several contacts on the external camera module. The spring pins in the electrical connector make pressure contact with the contacts on the back panel of the phone and the contacts on the external camera module, respectively, to achieve electrical connection between the phone and the external camera module.
[0004] Currently, due to the size limitations of the spring pins, the electrical connectors are relatively thick, resulting in poor convenience for users when using external camera modules. Utility Model Content

Detailed Implementation
[0056] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings.
[0057] The terminology used in the embodiments of this disclosure is for illustrative purposes only and is not intended to limit the disclosure.

The terms “upper,” “lower,” “left,” “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described object changes.
[0058] This disclosure provides an electrical connector, such as... Figure 1 and Figure 2 As shown, the electrical connector includes a base 1 and a connector 2.
[0059] The base 1 is a component in the electrical connector that provides support for the connector 2. (See also...) Figure 1 and Figure 2The base 1 may have a rectangular plate-like structure. The base 1 has a first wall 11 and a second wall 12 facing each other. The first wall 11 has a first mounting groove 111, and the second wall 12 has a second mounting groove 121. Both the first mounting groove 111 and the second mounting groove 121 are strip-shaped grooves. The first mounting groove 111 and the second mounting groove 121 extend in the same direction and are arranged opposite each other. The first mounting groove 111 has a first clearance area 1110, and the second mounting groove 121 has a second clearance area 1210.
[0060] Connector 2 is a component in an electrical connector used to contact the contacts of two electrical appliances, thereby electrically connecting the two appliances. See also Figure 1 and Figure 2 The connector 2 includes a first arm 21, a second arm 22, and a transition portion 23, with the first arm 21 and the second arm 22 respectively connected to the transition portion 23. Both the first arm 21 and the second arm 22 have a plate-like structure. The first arm 21 is installed in a first mounting groove 111, with its first end 211 facing the first clearance area 1110, and at least a portion of the first end 211 protruding from the first wall surface 11. The second arm 22 is located in a second mounting groove 121, with its second end 221 facing the second clearance area 1210, and at least a portion of the second end 221 protruding from the second wall surface 12. At least portions of both the second arm 22 and the first arm 21 are capable of elastic deformation.
[0061] In implementation, when the first end 211 is subjected to an external force, at least a portion of the first arm 21 undergoes elastic deformation, allowing the first end 211 to retract to a position where it does not protrude from the first wall surface 11. Correspondingly, when the second end 221 is subjected to an external force, at least a portion of the second arm 22 undergoes elastic deformation, allowing the second end 221 to retract to a position where it does not protrude from the second wall surface 12. Since at least a portion of the first arm 21 and at least a portion of the second arm 22 undergoes elastic deformation, after the external force is removed, the first arm 21 and the second arm 22 can respectively return to their initial states, causing the first end 211 to protrude again from the first wall surface 11, and the second end 221 to protrude again from the second wall surface 12.
[0062] Using the technical solution provided in this disclosure, the two arms of the connector 2 can undergo elastic deformation, thereby enabling the electrical connector to make pressurized contact with the contacts on the back panel of the mobile phone and the contacts on the external camera module. The space required for the spring pin to undergo elastic deformation of the connector 2 is smaller than that of the spring, thereby reducing the overall thickness of the electrical connector and improving the portability of the external camera module.
[0063] Optionally, the first clearance area 1110 and the second clearance area 1210 can both be blind hole structures, with the first clearance area 1110 located at the bottom of the first mounting groove 111 and the second clearance area 1210 located at the bottom of the second mounting groove 121.
[0064] Optionally, the first shelter zone 1110 and the second shelter zone 1210 can be connected.
[0065] In some possible embodiments, such as Figure 1 and Figure 2 As shown, the first end 211 has a first protrusion structure 211a on the side away from the second wall 12, and the second end 221 has a second protrusion structure 221a on the side away from the first wall 11.
[0066] In this way, by setting the first protrusion structure 211a and the second protrusion structure 221a, it is easier for the first end 211 and the second end 221 to make contact with the contacts on the back panel of the mobile phone and the contacts on the external camera module.
[0067] In some examples, both the first protrusion structure 211a and the second protrusion structure 221a are hollow conical protrusion structures with smooth transitions at the tips.
[0068] In practice, the first protrusion structure 211a and the second protrusion structure 221a can be formed by drawing and stamping process.
[0069] This design prevents the first protrusion structure 211a and the second protrusion structure 221a from scratching the contacts on the back panel of the phone and the contacts on the external camera module. Furthermore, the hollow structure of the first protrusion structure 211a and the second protrusion structure 221a saves materials and reduces the cost of the electrical connector.
[0070] In some possible embodiments, the electrical connector further includes a limiting structure for limiting the first arm 21 and the second arm 22.
[0071] like Figure 3 and Figure 4 As shown, the electrical connector also includes a first limiting structure 3 and a second limiting structure 4.
[0072] Specifically, the first limiting structure 3 is located at the opening of the first mounting groove 111 and is connected to the base 1. The first limiting structure 3 is used to restrict the movement of the first support arm 21 along the extension direction of the first mounting groove 111, and the top surface of the first protrusion structure 211a protrudes from the surface of the first limiting structure 3 away from the first wall surface 11. The second limiting structure 4 is located at the opening of the second mounting groove 121 and is connected to the base 1. The second limiting structure 4 is used to restrict the movement of the second support arm 22 along the extension direction of the second mounting groove 121, and the top surface of the second protrusion structure 221a protrudes from the surface of the second limiting structure 4 away from the second wall surface 12.
[0073] See in some examples Figure 3 and Figure 4 Both the first limiting structure 3 and the second limiting structure 4 have annular structures. The first limiting structure 3 is connected to the first wall surface 11, and the second limiting structure 4 is connected to the second wall surface 12.
[0074] Specifically, both the first limiting structure 3 and the second limiting structure 4 have a circular annular structure. The bottom surface of the first limiting structure 3 is connected to the first wall surface 11, and the bottom surface of the second limiting structure 4 is connected to the second wall surface 12. Both the first limiting structure 3 and the second limiting structure 4 have a through hole in their middle portions. A first protrusion 211a passes through the through hole of the first limiting structure 3, such that the tip of the first protrusion 211a protrudes beyond the top surface of the first limiting structure 3. A second protrusion 221a passes through the through hole of the second limiting structure 4, such that the tip of the second protrusion 221a protrudes beyond the top surface of the second limiting structure 4.
[0075] In one example, the base 1, the first limiting structure 3, and the second limiting structure 4 are integrally formed. In practice, the base 1, the first limiting structure 3, and the second limiting structure 4 can be integrally formed by pressure injection molding. The material used to make the base 1, the first limiting structure 3, and the second limiting structure 4 can be plastic, and this embodiment of the present disclosure does not limit this.
[0076] In some examples, such as Figure 8 and Figure 9 As shown, a first assembly opening 100 is formed between the first limiting structure 3 and the groove wall of the first mounting groove 111, allowing the first end 211 to pass through so that the first end 211 can be assembled into the first clearance area 1110. A second assembly opening 200 is formed between the second limiting structure 4 and the groove wall of the second mounting groove 121, allowing the second end 221 to pass through so that the second end 221 can be assembled into the second clearance area 1210.
[0077] Specifically, the bottom surface of the first limiting structure 3 may have a first clearance groove with the same width as the first mounting groove 111. The depth of the first clearance groove is not limited in this embodiment. The first clearance groove and the first mounting groove 111 form the aforementioned first assembly opening 100. The bottom surface of the second limiting structure 4 may have a second clearance groove with the same width as the second mounting groove 121. The depth of the second clearance groove is not limited in this embodiment. The second clearance groove and the second mounting groove 121 form the aforementioned second assembly opening 200.
[0078] In this way, by setting the first assembly port 100 and the second assembly port 200, the ease of assembly between the connector 2 and the base 1 can be improved.
[0079] In some possible embodiments, the first arm 21 and the second arm 22 each include multiple parts.
[0080] See Figure 5 The first arm 21 includes a first connecting part 2101, a first deformable part 2102 and a first contact part 2103 connected in sequence. The first connecting part 2101 is in contact with the bottom of the first mounting groove 111. One end of the first deformable part 2102 is located inside the first mounting groove 111 and the other end extends out of the first mounting groove 111. The first deformable part 2102 can undergo elastic deformation. The first contact part 2103 is arranged opposite to the first clearance area 1110.
[0081] Furthermore, the second arm 22 includes a second connecting part 2201, a second deformable part 2202, and a second contact part 2203 connected in sequence. The second connecting part 2201 is connected to the first connecting part 2101 and is in contact with the bottom of the second mounting groove 121. One end of the second deformable part 2202 is located inside the second mounting groove 121, and the other end extends out of the second mounting groove 121. The second deformable part 2202 can undergo elastic deformation. The second contact part 2203 is arranged opposite to the second clearance area 1210.
[0082] Specifically, see Figure 5The first connecting portion 2101 is arranged parallel to the bottom of the first mounting groove 111. The first connecting portion 2101 is connected to one end of the transition portion 23, and the side wall of the first connecting portion 2101 near the bottom of the first mounting groove 111 is completely fitted to the bottom of the first mounting groove 111. The first deformable portion 2102 has an included angle with the bottom of the first mounting groove 111, which can be between 10° and 15°. The first contact portion 2103 is used to contact the contacts of the electrical appliance. The second connecting portion 2201 is arranged parallel to the bottom of the second mounting groove 121. The second connecting portion 2201 is connected to one end of the transition portion 23, and the side wall of the second connecting portion 2201 near the bottom of the second mounting groove 121 is completely fitted to the bottom of the second mounting groove 121. The second deformable part 2202 has an included angle with the bottom of the second mounting groove 121, which can be between 10° and 15°. The second contact part 2203 is used to make contact with the contacts of the electrical appliance.
[0083] In implementation, the first contact portion 2103 and the second contact portion 2203 contact the contacts on the mobile phone and the external camera module, respectively. When the first contact portion 2103 and the second contact portion 2203 contact the contacts, they are subjected to compressive force, causing the first deformation portion 2102 and the second deformation portion 2202 to undergo elastic deformation. This causes the first contact portion 2103 to retract into the first mounting groove 111, and the second contact portion 2203 to retract into the second mounting groove 121. After the first contact portion 2103 and the second contact portion 2203 separate from the contacts, the first deformation portion 2102 and the second deformation portion 2202 cause the first contact portion 2103 and the second contact portion 2203 to extend back to their initial positions.
[0084] In some examples, the first arm 21 and the second arm 22 support the fixed base 1.
[0085] Specifically, see Figure 5 The first connecting part 2101, the transition part 23, and the second connecting part 2201 are connected in sequence. The first connecting part 2101 and the second connecting part 2201 are spaced apart. The gap between them can be less than the distance between the bottom of the first mounting groove 111 and the bottom of the second mounting groove 121, so that the first connecting part 2101 and the second connecting part 2201 clamp and fix the base 1.
[0086] This improves the connection stability between connector 2 and base 1.
[0087] In some possible embodiments, the electrical connector includes a plurality of connectors 2.
[0088] like Figure 6 and Figure 7As shown, the first wall surface 11 has a plurality of first mounting slots 111, and the second wall surface 12 has a plurality of second mounting slots 121. The electrical connector includes a plurality of connectors 2, each connector 2 having a first arm 21 located in a first mounting slot 111 and a second arm 22 located in a second mounting slot 121.
[0089] Furthermore, the extension directions of the plurality of first mounting slots 111 are parallel, and the extension directions of the plurality of second mounting slots 121 are parallel. Each connector 2 is assembled in a pair of oppositely arranged first mounting slots 111 and second mounting slots 121.
[0090] Thus, the electrical connector includes multiple connectors 2, which can be adapted to mobile phones and external camera modules with multiple contacts.
[0091] The technical solutions provided in this disclosure include at least the following beneficial effects.
[0092] This disclosure provides an electrical connector in which at least a portion of the first arm 21 and the second arm 22 can undergo elastic deformation, thereby enabling the electrical connector to make pressurized contact with contacts on the back panel of a mobile phone and contacts on an external camera module. The space required for the spring pin to undergo elastic deformation of the connector 2 is smaller than that of the spring, thereby reducing the overall thickness of the electrical connector and improving the portability of the external camera module.
[0093] This disclosure provides a protective case for a portable terminal device. The protective case has a receiving cavity for accommodating the aforementioned electrical connector. It is readily understood that the protective case is snapped onto a portable terminal device such as a mobile phone. The protective case has clearance holes at positions corresponding to the contacts of the mobile phone and the external camera module, allowing the aforementioned first and second ends to protrude.
[0094] This disclosure provides an external camera module, which includes the protective case and housing cavity of the portable terminal device described above.
[0095] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
