[0036] Please refer to Figures 1 to 9 , is a double-row FPC connector 100 described in an embodiment, which can be applied to new energy vehicles to achieve plug-in electrical connection of devices with different functions.

[0037] Exemplarily, the double-row FPC connector 100 includes a socket assembly 10 and a line row assembly 20. The socket assembly 10 includes a socket 11 and a terminal unit 12, the socket 11 is formed with a plug-in cavity, the terminal unit 12 is provided with a plug-in portion, the plug-in portion is arranged in the plug-in cavity and is an elastic protrusion structure; the FPC assembly 20 includes an FPC seat 21 and an FPC unit 22, the FPC unit 22 is installed in the FPC seat 21, the FPC seat 21 is plugged into the plug-in cavity, and the plug-in portion elastically abuts against the contacts of the FPC unit 22.

[0038] The implementation of the embodiment of the utility model will have the following beneficial effects: the double-row FPC connector 100 of the above scheme is composed of a socket assembly 10 and a line row assembly 20 for plugging and assembly, wherein a terminal unit 12 is installed on the socket 11, and the plug-in portion of the terminal unit 12 extends into the plug-in cavity, and the FPC unit 22 is installed in the FPC seat 21. When the FPC seat 21 is inserted into the plug-in cavity, the contact of the FPC unit 22 is in sliding contact with the plug-in portion with the elastic protrusion structure, and not only the contact area is small, but also the elastic protrusion structure has a yielding effect on the FPC unit 22. Therefore, the resistance of the FPC unit 22 and the terminal unit 12 to the plug-in contact surface is small, making the plug-in operation of the socket assembly 10 and the line row assembly 20 convenient and labor-saving; when the socket assembly 10 and the line row assembly 20 are plugged in place, the FPC unit 22 The contact points of 2 maintain elastic contact with the plug-in portion of the elastic protrusion structure, thereby ensuring reliable contact, helping to eliminate poor contact caused by assembly position errors, vibration displacement, etc., and further ensuring the electrical connection performance of the double-row FPC connector 100 after assembly.

[0039] like Figure 3 As shown, specifically, in the above embodiment, the terminal unit 12 includes a plurality of first terminals 121 and a plurality of second terminals 122 arranged side by side and spaced apart in the width direction of the double-row FPC connector 100, the plurality of first terminals 121 and the second terminals 122 are stacked in the thickness direction of the double-row FPC connector 100, the first terminal 121 is provided with a first elastic protrusion 121a, the second terminal 122 is provided with a second elastic protrusion 122a, and the first elastic protrusion 121a and the second elastic protrusion 122a are arranged to protrude back to back.

[0040] The FPC unit 22 includes a first line row 221 and a second line row 222, the first line row 221 and the second line row 222 are stacked in the thickness direction of the double-row FPC connector 100, a plurality of first contacts are provided on the side of the first line row 221 facing the second line row 222, a plurality of second contacts are provided on the side of the second line row 222 facing the first line row 221, the first contacts are elastically abutted against the first elastic protrusions 121a in a one-to-one correspondence, and the second contacts are elastically abutted against the second elastic protrusions 122a in a one-to-one correspondence.

[0041] The FPC unit 22 includes a first line row 221 and a second line row 222, which can meet the needs of more wiring harnesses to connect with more functional devices. Each first elastic protrusion 121a elastically abuts against the corresponding first contact, and each second elastic protrusion 122a elastically abuts against the corresponding second contact, which can ensure stable and reliable connection and avoid the generation of connection gaps that affect the electrical connection performance of the double-row FPC connector 100.

[0042] Optionally, the first elastic protrusion 121a and the second elastic protrusion 122a are both arc-shaped protrusions formed by a bending process. Therefore, when relatively slidingly plugged in, the contact friction resistance between the first elastic protrusion 121a and the first contact and the second elastic protrusion 122a and the second contact is smaller and wear is lighter, which helps to reduce the difficulty of plugging the socket assembly 10 and the wire row assembly 20 and improve the service life.

[0044] The first terminal 121 and the second terminal 122 are respectively inserted into the corresponding mating holes 111 to achieve independent installation without interfering with each other, which helps to improve the stability of signal transmission; and the retaining protrusion contacts the hole wall of the mating hole 111 to achieve installation limit of the first terminal 121 and the second terminal 122, preventing the first terminal 121 and the second terminal 122 from loosening, shifting or even falling, causing the connection between the first terminal 121 and / or the second terminal 122 and the wire row assembly 20 to fail, affecting the electrical connection reliability of the double-row FPC connector 100.

[0045] like Fig. 9 As shown, similarly, in another optional embodiment, a mounting cavity is provided inside the FPC seat 21, and a first strip protrusion 211 and a second strip protrusion 212 are protruded on the inner wall of the mounting cavity toward the middle of the mounting cavity, the first line row 221 is provided with a first strip slot 221a, the second line row 222 is provided with a second strip slot 222a, the first strip protrusion 211 is inserted into the first strip slot 221a, and the second strip protrusion 212 is inserted into the second strip slot 222a.

[0048] Furthermore, the clip 13 is also provided with a positioning column 132, the seat body is provided with a first positioning hole 214, the first line row 221 is provided with a second positioning hole 221b, the second line row 222 is provided with a third positioning hole 222b, the first positioning hole 214, the second positioning hole 221b and the third positioning hole 222b are stacked and aligned in the thickness direction of the double-row FPC connector 100, and the positioning column 132 is sequentially inserted into the first positioning hole 214, the second positioning hole 221b and the third positioning hole 222b.

[0049] During assembly, the buckle clip 13 is first separated from the seat body.

Then, the buckle clip 13 is buckled into the seat body from top to bottom, and the positioning column 132 passes through the first positioning hole 214, the second positioning hole 221b and the third positioning hole 222b in sequence, so that the first line row 221, the second line row 222 and the seat body are connected and fixed. The buckle clip 13 is assembled and fixed to the seat body by the buckle connection of the hook 131 and the bayonet 213, thereby obtaining a line row assembly 20 with a stable structure.

[0050] like Figure 1As shown, in addition, in another optional embodiment, one of the socket 11 and the FPC seat 21 is provided with a buckle body 112, and the other of the socket 11 and the FPC seat 21 is provided with a buckle plate 215, and the buckle body 112 is buckled and connected with the buckle plate 215. The socket 11 can be assembled and fixed with the FPC seat 21 as a whole, and the relative position of the socket assembly 10 and the line row assembly 20 is kept fixed, that is, the effect of ensuring the stable contact between the terminal unit 12 and the FPC unit 22 is achieved, and the electrical connection performance of the double-row FPC connector 100 after assembly is improved.
