[0051] Embodiment 1

[0052] like Figure 1-Figure 8 As shown, the present invention provides a connector, including a bearing seat body 1 and a plurality of terminals 2. The outer surface of the bearing seat body 1 is provided with a long strip-shaped positioning groove 11, the length direction of the positioning groove 11 is parallel to the first direction, the width direction is parallel to the second direction, the second direction is perpendicular to the first direction, an introduction port is provided on one side of the second direction of the positioning groove 11, the positioning groove 11 is configured to position and lay welding rods, and a plurality of terminals 2 are respectively arranged on the bearing seat body 1, and the terminals 2 are provided with a first connecting portion 21, and the first connecting portion 21 extends into the positioning groove 11 as a welding pad, and the first connecting portions 21 of the plurality of terminals 2 are sequentially arranged in the positioning groove 11 along the first direction at intervals, and the wire cores of the plurality of cables 100 can extend into the positioning groove 11 through the introduction port, and be welded to the plurality of first connecting portions 21 one by one.

[0053] In the present invention, the connector can connect the flexible circuit board 200 and multiple cables 100 through the terminals 2 thereon. When connecting the cables 100, the first connecting part 21 of the terminal 2 is accommodated in the positioning groove 11 on the supporting seat body 1. The wire cores of the multiple cables 100 can extend into the positioning groove 11 through the introduction port and abut against the multiple first connecting parts 21 one by one. The positioning groove 11 is in a long strip shape and can limit the position of the welding rod, so that the welding operation is safer, more reliable, simpler and more efficient, and the wire cores of the multiple cables 100 and the multiple first connecting parts 21 can be welded one by one. Finally, the flexible circuit board 200 can be efficiently connected to the multiple cables 100, and the positioning groove 11 also makes the connection between the wire core of the cable 100 and the first connecting part 21 retracted, which plays a protective role.

[0054] In the present invention, the welding rod is a tin rod. After the copper core of the cable 100 is fixedly contacted with the first connecting portion 21 in the positioning groove 11, the tin rod is horizontally pulled over the core, and then welded using an HB welding machine or manually welded using a soldering iron.

[0055] Specifically, the outer surface of the bearing seat body 1 is provided with a plurality of through channels 12, the through channels 12 extend along the second direction, the inlet is connected to the outside through the through channels 12, and each through channel 12 is configured to limit and accommodate a cable 100. By providing the through channels 12, the cables 100 are organized to be aligned more accurately on the bearing seat body 1.

[0056] More specifically, the positioning groove 11 is arranged to penetrate along the first direction, so as to facilitate the movement of the welding rod.

[0057] In this embodiment, the bottom of the positioning groove 11 is provided with a receiving groove 111, and the first connecting portion 21 is located in the receiving groove 111. By providing the receiving groove 111, the first connecting portion 21 is limited and accommodated, so that the first connecting portion 21 is more accurately positioned on the bearing seat body 1.

[0058] Specifically, the positioning groove 11 is provided with a positioning wall 112, and the positioning wall 112 and the introduction port are located on the inner walls on both sides opposite to each other of the positioning groove 11, and the positioning wall 112 is configured to align the ends of the wire cores of the plurality of cables 100. By providing the positioning wall 112, the wire cores of the plurality of cables 100 can be aligned, thereby ensuring the reliability of the connection between the wire cores and the first connecting portion 21.

[0059] In this embodiment, the first connecting portion 21 extends from the through channel 12 to the accommodating groove 111 in the positioning groove 11, and abuts against the positioning wall 112. The portion of the first connecting portion 21 in the positioning groove 11 protrudes from the bottom of the positioning groove 11 and is higher than the portion in the through channel 12, so that the cable 100 wrapped with the outer sheath is coaxial and straight with the core wire in the positioning groove 11 when it is limitedly clamped in the through channel 12.

[0060] Specifically, one end of the bearing seat body 1 is provided with an insertion slot 13, and the insertion slot 13 is configured to insert the flexible circuit board 200. The terminal 2 is provided with a second connection portion 22, and the second connection portion 22 extends into the insertion slot 13. When the flexible circuit board 200 is inserted into the insertion slot 13, it abuts against the second connection portion 22. By providing the insertion slot 13 and the second connection portion 22, the flexible circuit board 200 can be conveniently connected to the terminal 2, and then connected to multiple cables 100 through the terminal 2.

[0061] More specifically, a locking block 131 is disposed in the insertion slot 13 , and the flexible circuit board 200 is provided with a locking slot 201 . When the flexible circuit board 200 is inserted into the insertion slot 13 , the locking block 131 extends into the locking slot 201 .

[0062] More specifically, a locking groove 201 is provided on both sides of the flexible circuit board 200 in the width direction, and two locking blocks 131 are correspondingly provided in the insertion groove 13. When the flexible circuit board 200 is inserted into the insertion groove 13, the two locking blocks 131 extend into the two locking grooves 201 one by one.

[0063] In this embodiment, the insertion slot 13 includes a first slot 132, a transition slot 133, and a second slot 134 that are sequentially connected from the slot opening to the slot bottom. The first slot 132, the transition slot 133, and the second slot 134 have one side slot wall flush, which is set as a reference wall 135. The locking block 131 is located in the first slot 132 and is set on the reference wall 135. The reference wall 135 is provided with an inner groove. The second connecting portion 22 is partially located in the inner groove and partially extends into the second slot 134 through the reference wall 135. The slot wall on one side of the transition slot 133 is a guide wall 136. The guide wall 136 and the reference wall 135 are arranged facing each other, and from the end connected to the first groove 132 to the end connected to the second groove 134, the guide wall 136 gradually approaches the reference wall 135, and the angle between the extension direction of the second connection part 22 and the second direction is 10-15 degrees, so that when the flexible circuit board 200 is inserted into the insertion groove 13, the second connection part 22 can exert a certain abutment force on the flexible circuit board 200, so that the contact between the two is more stable, and the head of the second connection part 22 is provided with a barb protrusion, so that the contact with the flexible circuit board 200 is more sufficient.

[0064] In other embodiments, the connector further includes a locking frame 3, which is mounted on the bearing seat 1. The locking frame 3 is provided with a buckle 31. When the flexible circuit board 200 is inserted into the insertion slot 13, the buckle 31 replaces the locking block 131 and extends into the locking slot 201. The above arrangement enables the buckle 31 to be more flexibly matched with the locking slot 201 on the flexible circuit board 200.

[0065] More specifically, the locking frame 3 is provided with an elastic arm 32, which is configured to support the buckle 31 in a locked state. In the locked state, the buckle 31 extends into the insertion slot 13. When the elastic arm 32 is elastically deformed by force, it can drive the buckle 31 to move to an avoidance state. In the avoidance state, the buckle 31 withdraws from the insertion slot 13. The above arrangement facilitates the insertion and removal of the flexible circuit board 200 in the insertion slot 13.

[0066] Specifically, the buckle 31 is provided with a pressing surface 311, and the flexible circuit board 200 can drive the buckle 31 to withdraw from the insertion slot 13 by pushing the pressing surface 311. The above arrangement enables the flexible circuit board 200 to pass over the locking block 131 during the insertion process, and can be locked by the locking block 131 after being inserted into place.

[0067] More specifically, the bearing seat body 1 is provided with an avoidance groove 14, and the insertion groove 13 is connected to the avoidance groove 14. In the locked state, the buckle 31 extends from the avoidance groove 14 into the insertion groove 13, and in the avoidance state, the buckle 31 retreats from the insertion groove 13 to the avoidance groove 14. By providing the avoidance groove 14, space is provided for the movement and avoidance of the buckle 31.

[0068] Specifically, the elastic support arm 32 abuts against the bottom of the avoidance groove 14. The above arrangement provides reliable support for the deformation of the elastic support arm 32.

[0069] More specifically, one of the bearing seat body 1 and the locking frame 3 is provided with a hooking groove 15, and the other is provided with a hook head 33, and the hook head 33 is hooked in the hooking groove 15. The above arrangement enables the locking frame 3 to be flexibly and conveniently assembled and disassembled from the bearing seat body 1.

[0070] In this embodiment, the locking frame 3 is a metal part, which is prepared in one piece through a sheet metal process. The elastic support arm 32 is bent in an S shape. A hook head 33 is respectively provided at both ends of the first direction of the locking frame 3, and a hook groove 15 is respectively provided on the two opposite side walls of the supporting seat body 1. The two hook heads 33 are hooked in the two hook grooves 15 one by one.
