Specifically, in order to solve the problem that the line-end connector equipped with a power connection part adapted to a small current board-end connector in the prior art may be mistakenly inserted into a large current board-end connector, which poses a safety hazard; the line-end connector provided by the utility model integrates a first electrical connection part 2 and a second electrical connection part 3, including a power connection part and a signal connection part, has a compact structure and saves space, and the arrangement of the plug-in part 4 and the first positioning part 5 can respectively be plugged and matched with the plug-in slot 14 and the positioning slot 15 on the board-end connector, thereby ensuring the stability of the plug-in; at the same time, the arrangement of the thickened part 6 on the first positioning part 5 makes the surface of the first positioning part 5 away from the first electrical connection part 2 and the second electrical connection part 3 protrude toward the outside of the line-end connector from the surface of the plug-in part 4 away from the first electrical connection part 2 and the second electrical connection part 3, so that the first positioning part 5 cannot be mistakenly inserted into the plug-in slot 14 on the board-end connector, which can avoid the line-end connector equipped with a power connection part adapted to a small current board-end connector from being mistakenly inserted into a large current board-end connector.

In this embodiment, the line-end connector is a line-end connector configured with a power connection portion and adapted to a low-current board-end connector.

In this embodiment, the shape of the thickened portion 6 matches the shape of the surface of the first positioning portion 5 away from the first electrical connecting portion 2 and the second electrical connecting portion 3 , and the thickened portion 6 is formed along the surface as a whole.

Optionally, the first electrical connection portion 2 is a power connection portion, and the second electrical connection portion 3 is a sideband signal connection portion.

Specifically, the line-end connector realizes the integration of power connection and sideband signal connection through the setting of the power connection part and the sideband signal connection part, expands the function of the line-end connector, realizes a multifunctional integrated design, and realizes the integration of the functions of the electrical connector on the basis of the integration of the number of electrical connection parts.

Optionally, a wire outlet 7 is provided on one side of the first insulator 1 , and the first cable and the second cable extend outward through the wire outlet 7 .

Specifically, according to different outgoing line directions, the line end connector can be divided into a front outgoing line connector, a top outgoing line connector and a rear outgoing line connector.

Optionally, at least the front side of the bottom of the first insulator 1 is provided with an inserting portion 4 and a first positioning portion 5 , a locking buckle 8 is provided on the inserting portion 4 located on the front side of the bottom of the first insulator 1 , and a locking protrusion 9 is provided on the locking buckle 8 .

Specifically, a lock buckle 8 is provided on the plug-in portion 4 located on the front side of the first insulator 1, and the wire outlet 7 can be located on the rear side or top of the first insulator 1 to form a rear-side wire outlet connector or a top-side wire outlet connector, otherwise it forms a front-side wire outlet connector or a top-side wire outlet connector, which can facilitate the operation of the lock buckle 8.

In this embodiment, the rear side of the first insulator 1 is also provided with an inserting portion 4 and a first positioning portion 5 .

Regardless of whether one plug-in portion 4 and one first positioning portion 5 are simultaneously arranged on the front and rear sides of the first insulator 1, or two plug-in portions 4 and two first positioning portions 5 are respectively arranged on the front and rear sides of the first insulator 1, the first positioning portion 5 can be thickened compared to the plug-in portion 4 by means of a thickened portion 6 arranged on the surface of the first positioning portion 5 away from the first electrical connection portion 2 and the second electrical connection portion 3, thereby preventing the first positioning portion 5 from being mistakenly inserted into the plug-in slot 14 of the board-end connector.

Optionally, the lock buckle 8 includes a lock plate bent into a U shape, one side of the lock plate is snapped into a lock groove on the surface of the plug-in part 4, the other side of the lock plate is a free end and exposed, two lock protrusions 9 are arranged on the outside of the other side of the lock plate, and a pull strap 10 is arranged on the upper end of the other side of the lock plate.

Specifically, the locking plate bent into a U shape is elastic. When the pull strap 10 is pulled or the other side of the locking plate is pressed, the locking protrusion 9 on the other side of the locking plate can be driven to retract from the locking hole 16 on the board-end connector. At this time, the wire-end connector can be pulled out. At the same time, utilizing the elasticity of the locking plate, when the wire-end connector is inserted into the board-end connector, the locking protrusion 9 of the wire-end connector can be snapped into the locking hole 16 on the board-end connector, thereby realizing the snap-on fixation of the wire-end connector.

Optionally, it further includes a printed circuit board, the upper part of which is arranged in the first insulator 1, and the lower part of which extends downward to form a plug-in board portion 11, and the first electrical connection portion 2 and the second electrical connection portion 3 are arranged on the plug-in board portion 11 at intervals.

Specifically, the first electrical connection part 2 and the second electrical connection part 3 are integrated on the same printed circuit board, which is formed with a downwardly extending plug-in part 11, and the plug-in part 11 is provided with a conductive part for plugging with the terminal group on the board-end connector. The plug-in part 11 can be configured as an integral type, carrying the first conductive part of the power connection part and the second conductive part of the signal connection part. The plug-in part 11 can also be configured as a split type, and the two plug-in parts 11 respectively carry the first conductive part of the power connection part and the second conductive part of the signal connection part; in the present embodiment, the first electrical connection part 2 and the second electrical connection part 3 are arranged on the same plug-in part 11, and a sufficient electrical gap is maintained between the two by setting the spacing between the two.

The top surface of the first conductive portion is flush with the top surface of the second conductive portion or the top surface of the first conductive portion is higher than the top surface of the second conductive portion, as shown in FIG. 8 and FIG. 9 respectively.

Optionally, a second positioning portion 12 extending downward is provided on the left side or the right side of the first insulator 1 , and a second gap is formed between the second positioning portion 12 and the plug-in portion 4 .

Specifically, when the line-end connector is plugged into the corresponding board-end connector, the second positioning portion 12 fits against the outer side of the outer shell 13 of the board-end connector, which can play a role in plug-in positioning and guiding, thereby improving the stability of plug-in; at the same time, the existence of the second positioning portion 12 makes it possible for the line-end connector to be plugged in only against one end face of the board-end connector, and it is impossible to only insert the first positioning portion 5 into the positioning groove 15 on the board-end connector and insert the plug-in portion 4 into the plug-in groove 14 when plugging into the board-end connector. It is also necessary to consider the insertion requirement that the second positioning portion 12 fits against the outer shell 13 of the board-end connector, so as to further avoid the situation where the line-end connector equipped with a power connection portion adapted to a small current board-end connector is mistakenly inserted into a large current board-end connector.

As shown in FIG. 2 , the high-current board-end connector has two mis-insertion situations during the plug-in mating process of the line-end connector. The first mis-insertion situation is as described above, that is, both the plug-in portion 4 and the first positioning portion 5 of the line-end connector are inserted into the plug-in slot 14 of the board-end connector. This mis-insertion situation can be avoided by providing the first positioning portion 5 with a thickened portion 6. The second mis-insertion situation is that although the first positioning portion 5 is provided with a thickened portion 6, the first positioning portion 5 can still be inserted into the positioning slot 15 of the board-end connector, and the plug-in portion 4 can be inserted into the plug-in slot 14 of the board-end connector. Although the plug-in slot 14 is not fully inserted, it can still be inserted, and this mis-insertion situation still exists. The provision of the second positioning portion 12 enables the line-end connector to be plugged only against one end face of the board-end connector, thereby avoiding the occurrence of this mis-insertion situation.

Optionally, the plug-in portion 4 is plate-shaped, the first positioning portion 5 is column-shaped, and the second positioning portion 12 is plate-shaped.

As shown in FIG. 10 , the utility model further provides a connector assembly, including a board-end connector and the above-mentioned line-end connector.

Optionally, the board-side connector includes:

A second insulator, wherein a first terminal group and a second terminal group are sequentially arranged inside the second insulator along its length direction, and the first terminal group and the second terminal group are plug-matched with the first electrical connection part 2 and the second electrical connection part 3 respectively;

The shell 13 is sleeved on the outside of the second insulator, and a plug-in groove 14 is formed between at least one of the front and rear side surfaces of the second insulator and the shell 13. At least a portion of the front end surface and/or the rear end surface of the shell 13 is recessed inward to form a positioning groove 15. The plug-in groove 14 is plug-fitted with the plug-in portion 4, and the positioning groove 15 is plug-fitted with the first positioning portion 5.

Specifically, the board-end connector is an integrated board-end connector. When the line-end connector is plugged into the above-mentioned board-end connector, the plug-in portion 4 is inserted into the plug-in slot 14, and the first positioning portion 5 is inserted into the positioning slot 15; in the present embodiment, the second positioning portion 12 is attached to one end surface of the outer shell 13 of the board-end connector for plugging, and the locking protrusion 9 is inserted into the locking hole 16 on the outer shell 13; this can not only realize the reliable plug-in and fixation of the line-end connector on the board-end connector, but also avoid the occurrence of wrong insertion.

The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
