Description

[0002] At present, the connection of internal modules of a mobile phone mainly depends on a BTB (Board to Board) connector. The BTB connector occupies a small space and thus can meet the stacking requirements of an electronic device. Moreover, the BTB connector is widely used in electronic devices because it is convenient to assemble and can be designed in various forms to meet the requirements of increasing functions of electronic devices, such as large current, high integration and high reliability. As the functions of electronic devices are more and more, more and more signal terminals need to be arranged on the BTB connector to meet the signal transmission corresponding to different functions. However, the more the number of terminals is, the longer the connector body is, and thus the coplanarity of the connector is not easy to control, that is, the connector body is prone to present a state of being arched in the middle after passing through the oven with the two ends being raised. When two connector bodies are docked, the corresponding signal terminals located in the middle position are prone to be virtually buckled, that is, the two corresponding signal terminals are prone to be in poor contact, thereby affecting the normal use of the BTB connector.

[0049] The specific embodiments of the present application have been shown and described in the above-described drawings, and will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work fall within the scope of protection of the present application.

[0051] Unless otherwise defined, all the technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0052] In order to make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below in combination with the drawings.

[0053] In a first aspect, in combination with Figure 1 and Figure 2As shown, the embodiment of the present application provides a connector assembly, which comprises a first connector 100 and a second connector 200. It should be noted that one of the first connector 100 and the second connector 200 in the embodiment of the present application is a male connector in a board-to-board connector, and the other is a female connector in the board-to-board connector. The drawings of the present application are taken as an example that the first connector 100 is the female connector and the second connector 200 is the male connector.

[0054] The first connector 100 comprises a first seat body 110 and a first clamping piece 120. The first seat body 110 is provided with a through hole 111. The first clamping piece 120 is mounted on the first seat body 110, and at least a part of the first clamping piece 120 is located in the through hole 111. The second connector 200 comprises a second seat body 210 and a second clamping piece 220. The second clamping piece 220 is mounted on the second seat body 210, and at least a part of the second clamping piece 220 is exposed from the second seat body 210. It should be noted that the first seat body 110 and the second seat body 210 may, for example, both be made of plastic. The first clamping piece 120 and the second clamping piece 220 may, for example, both be made of metal.

[0055] Wherein, when the first connector 100 and the second connector 200 are connected, the part of the second clamping piece 220 exposed from the second seat body 210 extends into the through hole 111 along the connection direction and is clamped and matched with the first clamping piece 120.

[0056] It should be noted that, since the first clamping piece 120 and the second clamping piece 220 can be clamped together when the first connector 100 and the second connector 200 are connected, the first seat body 110 connected with the first clamping piece 120 and the second seat body 210 connected with the second clamping piece 220 can be kept close to each other. Then, even if the first connector 100 and the second connector 200 are arched in the middle after passing through the furnace, the clamping and matching of the first clamping piece 120 and the second clamping piece 220 can reduce the gap between the first connector 100 and the second connector 200 due to the arching, so as to avoid the poor contact of the two connectors after being connected.

[0057] The details and effects of the connector assembly provided by the embodiment of the present application will be described more specifically and in detail. Figures 1 to 9 The details and effects of the connector assembly provided by the embodiment of the present application will be described more specifically and in detail.

[0058] As Figure 3As shown, in some embodiments, the first clamping member 120 comprises oppositely arranged first and second clamping portions 121 and 122. The first clamping portion 121 comprises a first fixed arm 123 connected with the first seat member 110 and a first elastic arm 124 extending into the through hole 111. The second clamping portion 122 comprises a second fixed arm 125 connected with the first seat member 110 and a second elastic arm 126 extending into the through hole 111. The first and second elastic arms 124 and 126 are close to each other and used to clamp the part of the second clamping member 220 exposed from the second seat member 210. It can be understood that the first and second elastic arms 124 and 126 can pull the distance between the first and second plastic members and avoid the disconnection of the first and second connectors 100 and 200 after the connection, thereby improving the stability of the connector assembly.

[0059] In combination Figure 3 and Figure 9 As shown, in some embodiments, the second clamping member 220 comprises a fixed portion 221 and a third clamping portion 222. A part of the fixed portion 221 is embedded in the second seat member 210, and another part is exposed from the surface of the second seat member 210 away from the first connector 100 and adapted to be connected with the first circuit board 300. The two sides of the third clamping portion 222 are respectively clamped and matched with the first and second elastic arms 124 and 126. It should be noted that the part of the fixed portion 221 embedded in the second seat member 210 in the embodiments of the present application can mean that the part of the fixed portion 221 is integrally molded with the second seat member 210 by the injection molding process, so as to stably fix the second clamping member 220 on the second seat member 210. Moreover, the part of the fixed portion 221 exposed from the second seat member 210 can be connected with the first circuit board 300 by welding, so as to stably fix the second connector 200 on the first circuit board 300. It should be noted that the first circuit board 300 in the embodiments of the present application can be a flexible circuit board or a printed circuit board.

[0060] In combination Figure 3 and Figure 4As shown, in some embodiments, the first elastic arm 124 and the second elastic arm 126 are folded towards each other to form a first folded portion 1241 and a second folded portion 1261 respectively, and the two sides of the part of the second clamping member 220 exposed from the second seat member 210 abut against the first folded portion 1241 and the second folded portion 1261 respectively. It should be noted that the first folded portion 1241 and the second folded portion 1261 can respectively apply a pressing force to the two sides of the second clamping member 220, so that the first clamping member 120 can stably clamp the second clamping member 220, so that the first connector 100 and the second connector 200 can maintain a state of approaching each other.

[0061] In combination Figure 3 and Figure 5 As shown, in some embodiments, the two sides of the third clamping portion 222 are respectively provided with a first clamping groove 223 and a second clamping groove 224. When the first connector 100 and the second connector 200 are connected, the first folded portion 1241 is clamped into the first clamping groove 223, and the second folded portion 1261 is clamped into the second clamping groove 224. In this way, the clamping force of the first clamping member 120 on the second clamping member 220 can be further improved, so that the first connector 100 and the second connector 200 can maintain a state of approaching each other. At the same time, it can also prevent the first connector 100 and the second connector 200 from being separated from each other during the falling process of the connector assembly, the functional module provided with the connector assembly or the electronic equipment, thereby improving the stability and reliability of the connector assembly.

[0062] In combination Figure 3 and Figure 6 As shown, in some embodiments, the first elastic arm 124 has a first clamping hook 1242, and the second elastic arm 126 has a second clamping hook 1262, and the first clamping hook 1242 and the second clamping hook 1262 are oppositely arranged. The two sides of the third clamping portion 222 are respectively provided with a third clamping hook 225 and a fourth clamping hook 226. When the first connector 100 and the second connector 200 are connected, the first clamping hook 1242 and the third clamping hook 225 are clamped and matched, and the second clamping hook 1262 and the fourth clamping hook 226 are clamped and matched. In this way, the first elastic arm 124 and the second elastic arm 126 can be stably clamped together with the third clamping portion 222, so that the first connector 100 and the second connector 200 can maintain a state of approaching each other. At the same time, it can also prevent the first connector 100 and the second connector 200 from being separated from each other during the falling process of the connector assembly, the functional module provided with the connector assembly or the electronic equipment, thereby improving the stability and reliability of the connector assembly.

[0063] In combination Figure 3 and Figure 9As shown, in some embodiments, a portion of the first fixing arm 123 is embedded in the first seat member 110, and another portion thereof is exposed from a surface of the first seat member 110 facing away from the second connector 200 and is adapted to be connected to the second circuit board 400. A portion of the second fixing arm 125 is embedded in the first seat member 110, and another portion thereof is exposed from a surface of the first seat member 110 facing away from the second connector 200 and is adapted to be connected to the second circuit board 400. It should be noted that the portion of the first fixing arm 123 embedded in the first seat member 110 in the embodiments of the present application can mean, for example, that the portion of the first fixing arm 123 is integrally formed with the first seat member 110 by an injection molding process, so as to stably fix the first clamping member 120 on the first seat member 110. Moreover, the portion of the first fixing arm 123 exposed from the first seat member 110 and the second circuit board 400 can be connected by welding, so as to stably fix the first connector 100 on the first circuit board 300. It should be noted that the second circuit board 400 in the embodiments of the present application can be, for example, a flexible circuit board or a printed circuit board.

[0064] In combination Figure 7 And Figure 8 As shown, in some embodiments, the first connector 100 further comprises two first housings 130 and a first set of terminals 140, the two first housings 130 respectively wrapping two ends of the first seat member 110, and the first set of terminals 140 being installed on the first seat member 110. The second connector 200 further comprises two second housings 230 and a second set of terminals 240, the two second housings 230 respectively wrapping two ends of the second seat member 210, and the second set of terminals 240 being installed on the second seat member 210. When the first connector 100 and the second connector 200 are connected, the first set of terminals 140 and the second set of terminals 240 are electrically connected, and the first housings 130 and the corresponding second housings 230 are electrically connected. It should be noted that the first set of terminals 140, the second set of terminals 240, the first housings 130 and the second housings 230 can all be made of metal. It should be understood that the electrical connection between the first set of terminals 140 and the second set of terminals 240 can achieve signal transmission, and the first housings 130 and the second housings 230 can achieve current flow. Since the first clamping member 120 and the second clamping member 220 can bring the first connector 100 and the second connector 200 closer to each other, the phenomenon of virtual buckling between the first set of terminals 140 and the corresponding second set of terminals 240 can be avoided, that is, the phenomenon of poor contact between the first set of terminals 140 and the corresponding second set of terminals 240 can be avoided, so as to ensure the normal use of the connector assembly.

[0065] As Figure 7As shown, in some embodiments, the first set of terminals 140 includes a plurality of first terminals 141 and a plurality of second terminals 142. The plurality of first terminals 141 are arranged side by side on the first base body 110 along a first direction, and the plurality of second terminals 142 are arranged side by side on the first base body 110 along a second direction, wherein both the first direction and the second direction are parallel to the length direction of the first connector 100.

[0066] like Figure 8 As shown, in some embodiments, the second set of terminals 240 includes a plurality of third terminals 241 and a plurality of fourth terminals 242. The plurality of third terminals 241 are arranged side by side on the second body 210 along a third direction, and the plurality of fourth terminals 242 are arranged side by side on the second body 210 along a fourth direction, wherein both the third and fourth directions are parallel to the length direction of the second connector 200.

[0067] Combination Figure 7 and Figure 8 As shown, in some embodiments, the first base member 110 has a first groove 112, and a protrusion 113 is provided at the bottom of the first groove 112. A through hole 111 penetrates the bottom of the first groove 112 and the protrusion 113. The second base member 210 has a second groove 211, and at least a portion of the second snap-fit ​​member 220 extends into the second groove 211 from the bottom of the second groove 211. When the first connector 100 and the second connector 200 are mated, the second base member 210 snaps into the first groove 112, and the protrusion 113 snaps into the second groove 211. In this way, the first connector 100 and the second connector 200 can be stably mated together. In some embodiments, the first groove 112 includes opposing first groove walls 1121 and second groove walls 1122, a plurality of first terminals 141 are arranged side by side on the first groove wall 1121, and a plurality of second terminals 142 are arranged side by side on the second groove wall 1122. The second groove 211 includes a third groove wall 2111 and a fourth groove wall 2112 opposite to each other. A plurality of third terminals 241 are arranged side by side on the third groove wall 2111, and a plurality of fourth terminals 242 are arranged side by side on the fourth groove wall 2112. The third groove wall 2111 is opposite to the first groove wall 1121, and the fourth groove wall 2112 is opposite to the second groove wall 1122.

[0068] Combination Figure 1 and Figure 2As shown, in some embodiments, the through hole 111 is located at or near the center of the first seat body 110. It should be noted that after the first connector 100 and the second connector 200 pass through the oven, the two ends of the first connector 100 and the second connector 200 are generally raised, so when the first connector 100 and the second connector 200 are docked, the first connector 100 and the second connector 200 are prone to arching in the middle. The embodiments of the present application set the through hole 111 at or near the center of the first seat body 110, and the first clamping piece 120 and the second clamping piece 220 are clamped and matched in the through hole 111, so as to ensure that the center of the first seat body 110 and the center of the second seat body 210 are maximally close to each other, thereby causing the gap between the first seat body 110 and the second seat body 210 from the center to the two ends to be maximally reduced, and further ensuring that the first group of terminals 140 and the corresponding second group of terminals 240 can maintain good contact, and ensuring the stability of signal transmission of the connector assembly. It should be noted that the through hole 111 corresponds to the first clamping piece 120 one-to-one, and the first clamping piece 120 corresponds to the second clamping piece 220 one-to-one. The number of through holes 111 can be one, two or more. When the through hole 111 is two or more, the two or more through holes 111 are symmetrically distributed about the center of the first seat body 110. Thus, the gap formed by the first connector 100 and the second connector 200 due to arching in the middle can be maximally reduced, and further ensuring that the first group of terminals 140 and the second group of terminals 240 can maintain good contact, and ensuring the stability of signal transmission of the connector assembly.

[0069] In summary, the first clamping piece 120 and the second clamping piece 220 of the embodiments of the present application have a simple structure, which can cause the first connector 100 and the second connector 200 to be close to each other, thereby reducing the gap caused by the two ends of the first connector 100 and / or the second connector 200 being raised after passing through the oven and arching in the middle, and further causing the terminals on the first connector 100 and the second connector 200 to maintain good contact, ensuring the stability of signal transmission. At the same time, the first clamping piece 120 and the second clamping piece 220 are clamped to each other, which can increase the pull-out force of the first connector 100 or the second connector 200, and prevent the first connector 100 and the second connector 200 from being separated from each other due to falling, i.e., improving the reliability and stability of the connector assembly.

[0070] In combination Figures 1 to 9As shown, in the second aspect, the embodiments of the present application further provide a functional module, the functional module comprising the first circuit board 300, the second circuit board 400 and the connector assembly of any one of the first aspect of the embodiments of the present application, the first connector 100 being mounted on the first circuit board 300, and the second connector 200 being mounted on the second circuit board 400.

The first circuit board 300 may, for example, be a flexible circuit board or a printed circuit board. The second circuit board 400 may, for example, be a flexible circuit board or a printed circuit board. Since the first connector 100 and the second connector 200 can keep close to each other to maintain a good contact state, the stability of the signal transmission of the connector assembly can be ensured, and the stability of the function of the functional module can be improved.

[0071] In the third aspect, the embodiments of the present application further provide an electronic device, the electronic device comprising the connector assembly of any one of the first aspect of the embodiments of the present application, or comprising the functional module provided by the embodiments of the second aspect of the present application. It should be noted that the composition and function of the connector assembly in the electronic device provided by the embodiments of the present application are the same as those of the connector assembly of any one of the first aspect of the embodiments of the present application, respectively, and thus the embodiments of the present application will not be described here. Alternatively, the composition and function of the functional module in the electronic device provided by the embodiments of the present application are the same as those of the functional module of any one of the second aspect of the embodiments of the present application, respectively, and thus the embodiments of the present application will not be described here. Since the first connector 100 and the second connector 200 can keep close to each other to maintain a good contact state, the stability of the signal transmission of the connector assembly can be ensured, and the stability of the function of the functional module can be improved, and thus the stability of the function of the electronic device can be improved.
