Description

Technical Field

[0001] This application relates to the field of electronic technology, specifically to a connector assembly and an electronic device. Background Technology

[0002] A connector is a device that connects two active devices. Connectors bridge the gap between circuits that are blocked or isolated, enabling the transmission of current or signals and thus allowing the circuit to perform its functions. Board-to-board connectors are a common type of connector in electronic devices, generally consisting of male and female connectors. When the male and female connectors are joined together, they form a connector assembly, allowing for the transmission of current or signals between them. Typically, the connector assembly needs to be electrically connected to the circuit board to complete signal output and input. However, current connector-to-circuit connections are not robust enough, and loosening can easily occur, meaning the connector assembly has poor stability. Utility Model Content

Detailed Implementation

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.

[0050] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0051] Firstly, combining Figure 1 and Figure 2 As shown, this application embodiment provides a connector assembly, which includes a first connector 100 and a first circuit board 200. It should be noted that the first circuit board 200 in this application embodiment can be a flexible circuit board or a printed circuit board.

[0052] The first circuit board 200 has a first solder pad 210. The first connector 100 includes a first base 110 and a central island 120. The first base 110 has a first through hole 111, and the central island 120 has a first protrusion 121. The first protrusion 121 protrudes towards the first circuit board 200 and passes through the first through hole 111 to connect with the first solder pad 210. It should be noted that... Figure 3The first welding area A1 shown is the area at the bottom of the first base 110 corresponding to the first solder pad 210. Since the welding point of the first protrusion 121 is added to the first circuit board 200, it is possible to avoid the first connector 100 from becoming loose from the first circuit board 200, thereby further improving the stability of the connection between the first connector 100 and the first circuit board 200, that is, improving the stability of the connector assembly.

[0053] The following is in conjunction with the appendix Figures 1 to 7 The details and functions of the connector assembly provided in the embodiments of this application will be described in more specific and detailed manner.

[0054] Combination Figure 1 and Figure 3 As shown, in some embodiments, the surface of the first protrusion 121 facing the first circuit board 200 is flush with the surface of the first base 110 facing the first circuit board 200. Therefore, after the first connector 100 is soldered to the first circuit board 200, the position of the first protrusion 121 can be prevented from lifting, improving the stability and aesthetics of the connection between the first connector 100 and the first circuit board 200.

[0055] like Figure 2 As shown, in some embodiments, the first base 110 has a slot 112, the bottom of which has a first through hole 111. The slot 112 includes opposing first and second groove walls 113 and 114. The central island 120 includes a connected welding portion 122, a first retaining portion 123, and a second retaining portion 124. The first retaining portion 123 and the second retaining portion 124 are respectively connected to both sides of the welding portion 122. The first retaining portion 123 retains part of the first groove wall 113, and the second retaining portion 124 retains part of the second groove wall 114. The welding portion 122 has a first protrusion 121. It should be noted that by providing the first retaining portion 123 and the second retaining portion 124, the central island 120 can be flexibly and stably fixed on the first base 110, improving the assembly efficiency and stability of the first connector 100.

[0056] Combination Figure 1 and Figure 3 As shown, in some embodiments, a gap is formed between the portion of the soldering portion 122 without the first protrusion 121 and the first solder pad 210. It should be understood that this gap can accommodate solder, preventing localized protrusions or overflow from the area of ​​the soldering portion 122 after the first connector 100 is soldered to the first circuit board 200. This ensures both the strength of the solder joint and improves the aesthetics of the finished product.

[0057] like Figure 2As shown, in some embodiments, the first groove wall 113 is provided with a first insertion hole 115. One end of the first retaining part 123 is connected to the side of the welding part 122 facing the first groove wall 113, and the other end extends along the inner side of the first groove wall 113 and bends to be inserted into the first insertion hole 115. The second groove wall 114 is provided with a second insertion hole 116. One end of the second retaining part 124 is connected to the side of the welding part 122 facing the second groove wall 114, and the other end extends along the inner side of the second groove wall 114 and bends to be inserted into the second insertion hole 116. It should be noted that the first insertion hole 115 and the second insertion hole 116 can respectively position the first retaining part 123 and the second retaining part 124, thereby improving the efficiency of assembling the island 120 and the first base 110.

[0058] Combination Figure 1 and Figure 2 As shown, in some embodiments, the first connector 100 further includes a housing 130, which covers the end of the first base 110. It is understood that the housing 130 serves both to protect the first base 110 and to facilitate current flow after mating with the connector on the mating side. The housing 130 includes a first sidewall 131. The first sidewall 131 is inserted into the first through hole 111 via a slot 112 and abuts against the central island 120. The first sidewall 131 is connected to the first pad 210. It should be noted that since both the first sidewall 131 and the first protrusion 121 are connected to the first pad 210, i.e., the first sidewall 131 and the first protrusion 121 are connected to the same pad, the stability of the connection between the first base 110, the central island 120, and the housing 130 can be further improved, thereby enhancing the reliability of the connection between the first connector 100 and the first circuit board 200. Furthermore, the central island 120 can be made of metal. When the first connector 100 mates with the connector on the mating side, the housing 130 is generally used to facilitate current flow. After the central island 120 abuts against the housing 130, it is equivalent to increasing the current flow area of ​​the first connector 100, thereby improving the current flow capacity of the first connector 100.

[0059] Combination Figure 1 and Figure 2 As shown, in some embodiments, the first circuit board 200 is further provided with a second solder pad 220. The housing 130 also includes a connecting wall 132 and a second side wall 133. The two sides of the connecting wall 132 are respectively connected to the first side wall 131 and the second side wall 133. The second side wall 133 is disposed opposite to the first side wall 131 and abuts against the outer wall of the end of the first base 110. The second side wall 133 is connected to the second solder pad 220. It should be noted that... Figure 3The second welding area A2 shown is the area at the bottom of the first base 110 corresponding to the second pad 220. Welding the second sidewall 133 to the second pad 220 together can further improve the stability of the connection between the first connector 100 and the first circuit board 200.

[0060] Combination Figure 2 and Figure 4 As shown, in some embodiments, the slot 112 further includes a third slot wall 117, the two sides of which are connected to the first slot wall 113 and the second slot wall 114, respectively. The first side wall 131 includes a first wall surface 134, a second wall surface 135, and a third wall surface 136 connected in sequence. The first wall surface 134 and the third wall surface 136 respectively cover the inner side of the first slot wall 113 and the inner side of the second slot wall 114, and the second wall surface 135 covers the inner side of the third slot wall 117, wherein the orthographic projection of the second wall surface 135 onto the third slot wall 117 coincides with the third slot wall 117. Figure 1 and Figure 5 As shown, in some embodiments, the connector assembly further includes a second connector 300, which includes a second base 310 and a contact 320. The contact 320 is connected to the end of the second base 310 and is elastically deformable in the direction from the first groove wall 113 to the second groove wall 114. When the second connector 300 is inserted into the slot 112 to mate with the first connector 100, the contact 320 is in a deformed state and abuts against the first sidewall 131. It should be noted that in the embodiments of this application, the first connector 100 can be a female connector and the second connector 300 can be a male connector. The contact 320 is generally made of metal. After the first connector 100 and the second connector 300 mate, the contact 320 can keep the first connector 100 and the second connector 300 electrically connected to achieve the current-carrying function of the connector assembly. Simultaneously, when the first connector 100 mates with the second connector 300, the contact 320 undergoes elastic deformation under pressure. Under the action of elastic restoring force, both sides of the contact 320 exert compressive force on the first wall surface 134 and the third wall surface 136 respectively, thus making it difficult for the second connector 300 to detach from the first connector 100, improving the reliability of the connector assembly. Furthermore, a stable connection between the first connector 100 and the second connector 300 can be achieved through the contact 320 on the second connector 300, eliminating the need for receiving holes or other features on the third wall surface 136 to accommodate other connections between the first connector 100 and the second connector 300. This allows for a larger area on the first sidewall 131, and consequently, a larger area on the housing 130, ensuring a larger flow area after the first connector 100 and the second connector 300 mate, thereby improving the flow capacity of the connector assembly.

[0061] Combination Figure 6 and Figure 7 As shown, in some embodiments, the contact 320 includes a body portion 321, a first elastic arm 322, and a second elastic arm 323. The body portion 321 covers the end of the second seat 310, thereby protecting the second seat 310. The first elastic arm 322 and the second elastic arm 323 are connected to both sides of the body portion 321 and extend away from the body portion 321. When the first connector 100 and the second connector 300 are mated, the first elastic arm 322 abuts against the first wall surface 134, and the second elastic arm 323 abuts against the third wall surface 136. It should be noted that during the mating process of the first connector 100 and the second connector 300, the first elastic arm 322 and the second elastic arm 323 are first squeezed inward by the pressure of the first wall surface 134 and the third wall surface 136, respectively. When the first connector 100 and the second connector 300 are in place, the first elastic arm 322 and the second elastic arm 323 gradually expand outward. Under the action of the outward elastic restoring force of the first elastic arm 322 and the second elastic arm 323, the first elastic arm 322 and the first wall surface 134 are pressed against each other, and the second elastic arm 323 and the third wall surface 136 are pressed against each other. This ensures that the contact 320 and the first side wall 131 always remain in abutting state, which improves the stability of the docking of the first connector 100 and the second connector 300, and thus improves the stability and reliability of the connector assembly.

[0062] like Figure 7 As shown, in some embodiments, a portion of the first elastic arm 322 protrudes toward a side opposite to the second elastic arm 323, and a portion of the second elastic arm 323 protrudes toward a side opposite to the first elastic arm 322. Understandably, the protrusions further ensure that the first sidewall 131 is in contact with the contact member 320.

[0063] like Figure 7 As shown, in some embodiments, the contact 320 further includes at least one support arm 324. One end of the support arm 324 is connected to the body portion 321, and the other end extends away from the body portion 321. At least a portion of the support arm 324 is embedded in the second seat 310. It should be noted that the support arm 324 can both support the second seat 310, thereby increasing the strength of the second seat 310 and making the second seat 310 less prone to deformation, and stably connect the contact 320 and the second seat 310 together.

[0064] Combination Figure 1 and Figure 5As shown, in some embodiments, the connector assembly further includes a second circuit board 400. The end of the support arm 324 furthest from the body 321 is electrically connected to the second circuit board 400. It should be noted that the second circuit board 400 in this embodiment can be a flexible circuit board or a printed circuit board. The support arm 324 and the second circuit board 400 can be connected by soldering.

[0065] Combination Figure 2 and Figure 5 As shown, in some embodiments, the bottom of the slot 112 is provided with a boss 118, and the second connector 300 has a groove with the opening facing the first connector 100. The soldering part 122 is also provided with a second protrusion 125, which protrudes in a direction away from the first circuit board 200 and covers the end of the boss 118. When the first connector 100 is inserted into the slot 112 to mate with the second connector 300, the boss 118 is engaged in the groove, and the second protrusion 125 is located between the boss 118 and the inner wall of the groove. It should be noted that when the first connector 100 and the second connector 300 mate, the second protrusion 125 can provide better protection for the end of the boss 118, thereby preventing the groove wall of the second connector 300 from scraping against the end of the boss 118 during the mating process and preventing damage to the first connector 100 during the mating process.

[0066] Secondly, this application also provides an electronic device, which includes a connector assembly as described in any of the above embodiments. It should be noted that the composition and function of the connector assembly in this electronic device are the same as those in the above embodiments, and will not be repeated here. It is understood that the electronic device provided in this application can be a mobile phone, tablet, camera, or other device. Because the connector assembly has high stability, installing it in the electronic device can prevent parts of the connector assembly from becoming loose and affecting other components within the electronic device, thus improving the stability and reliability of the installation of various components inside the electronic device.
