The present application provides a new type of connector bracket, as shown in Figures 1 to 3, for fixing multiple wiring harness 7 connectors, including a main frame 1 and an extension frame 2 connected thereto, the main frame 1 including a frame with openings on both sides and a mounting post 15 arranged on the outer wall of the frame, the frame including at least one first mounting window 11 and a plurality of second mounting windows 12, the top wall and the bottom wall of the first mounting window 11 are respectively provided with a fixing hole 111 and a barb 112, and each second mounting window 12 is provided with an extended clamping structure 14 along the opening direction; the outer wall of the extension frame 2 is connected to the outer wall of the frame, and has a third mounting window 21 with openings on both sides, and the opening direction of the third mounting window 21 is perpendicular to the opening direction of the first mounting window 11 and the second mounting window 12. Furthermore, the outer wall of the extension frame 2 is integrally formed with the outer wall of the frame.

According to the novel connector bracket of the present application, a plurality of different types of wiring harness 7 connectors can be fixed by using the main frame 1 and the extension frame 2, which facilitates the installation of the wiring harness 7 integrating multiple functions, reasonably optimizes the layout of the wiring harness 7, and saves installation space.

In some embodiments, two opposite side walls of the expansion frame 2 are respectively provided with notches 22, and a clamping arm 23 extending in the same direction as the opening direction of the third installation window 21 is provided in the notch 22, one end of the clamping arm 23 is connected to the inner wall of the notch 22, and the other end is a free end, and the clamping arm 23 and the side wall of the expansion frame 2 are in the same plane. As shown in Figures 1 and 2, one end of the clamping arm 23 is connected to the inner wall of the notch 22, and the other end is a free end, so that the clamping arm 23 can be elastically deformed in a direction perpendicular to the inner wall, and the clamping arm 23 will be elastically deformed outwards under the pressure from the inside of the expansion frame 2, so that the connector is clamped in the inside of the expansion frame 2, and the clamping arm 23 will apply an inward force to the connector to fix the connector. Further, a limiting protrusion is provided at the free end of the clamping arm 23, and the limiting protrusion faces the inside of the expansion frame. In some embodiments, a limiting hole is provided on the side wall of the connector, and the connector is limited from being separated from the expansion frame by the cooperation of the limiting protrusion and the limiting hole.

In some embodiments, the clamping structure 14 includes a pair of vertical plates with one end disposed on the inner wall of the second installation window 12 and a clamping plate 141 connected to the other end of the vertical plates, and the clamping plate 141 is parallel to the inner wall of the second installation window 12. As shown in FIG2 , the clamping structure 14 is disposed on the inner wall of the second installation window 12, and includes a pair of vertical plates and a clamping plate 141 connected to the vertical plates. Generally, the clamping plate 141 is parallel to the inner wall of the second installation window 12.

In some embodiments, the clamping structure 14 further includes a limiting portion 142 protruding from the second installation window 12, the limiting portion 142 is connected to an end of the vertical plate away from the clamping plate 141 and/or the end surface of the second installation window 12, and a limiting hole is provided on the limiting portion 142. As shown in FIG. 2, the limiting portion 142 protruding from the second installation window 12 can not only limit the installation position of the mating connector, but also reduce the force on the side wall of the second installation window 12, thereby improving the stability of the bracket.

In some embodiments, there are multiple mounting posts 15, and at least one fourth mounting window 13 is formed between the multiple mounting posts 15 and the outer wall of the frame, and each mounting post 15 is integrally formed with a staple 151 at the end away from the frame. In general, as shown in FIG1 and FIG2 , two mounting posts 15 are provided on the main frame 1, and the two mounting posts 15 are respectively provided at both ends of an outer side wall of the frame, and a fourth mounting window 13 is formed between the two mounting posts 15 and the outer wall of the frame, and the fourth mounting window 13 is used to accommodate other wiring harnesses 7 that do not require connectors.

The present application also provides a wiring harness installation structure, including a fixed structure 3, a wiring harness 7 and the aforementioned new connector bracket, the wiring harness 7 includes a first connector 4, a plurality of second connectors 5, a PCB board 8 and a board-end connector 6 arranged on the PCB board 8, the first connector 4 is installed in the first installation window 11, the second connector 5 is installed in the second installation window 12, the board-end connector 6 is installed in the expansion frame 2, and the end of the wiring harness 7 is fixed to the fixed structure 3 through the new connector bracket. As shown in Figures 1 and 2, the opening direction of the third installation window 21 is perpendicular to the opening direction of the first installation window 11 and the second installation window 12, and is used to set the board-end connector 6, and the two conductive ends of the board-end connector 6 are both set with a PCB board 8, and the flat wiring harness can also be connected through the PCB board 8. The wiring harness installation structure of the present application can be applied to the installation of the wiring harness 7 in various usage scenarios.

The fixed structure 3 is generally a sheet metal inside the vehicle body, as shown in Figure 1, and the mounting column 15 is fixed to the sheet metal opening by a staple 151 set at the end of the mounting column 15. The fourth mounting window 13 between the two mounting columns 15 and the outer wall of the frame and the fixed structure 3 is a closed rectangle. Some wiring harnesses 7 that do not require connectors to be installed can be arranged in the fourth window to avoid the wiring harnesses 7 being distributed in a disorderly manner around the bracket, thereby improving the aesthetics of the wiring harness 7 arrangement and saving installation space.

In some embodiments, a protrusion and a groove are provided on the outside of the first connector 4, which correspond to the fixing hole 111 and the barb 112 of the first installation window 11, respectively, and the two are correspondingly snapped together to install the first connector 4 to the first installation window 11. Generally, the first connector 4 is connected to the common wiring harness 7 of the ordinary circuit, and this part of the wiring harness 7 is more, and the volume of the first connector 4 is also larger. Therefore, it can be seen in the figure that the area of the first installation window 11 is larger, and it is used to install the first connector 4. The first connector 4 is provided with a protrusion and a groove (not shown in the figure) matching the fixing hole 111 and the barb 112 on the outside to fix the first connector 4.

In some embodiments, a card slot and a limit hook (not shown in the figure) are provided on the outside of the second connector 5, and the card slot and the limit hook are respectively connected with the card connection structure 14, so that the second connector 5 is installed in the second installation window 12. Generally, the second connector 5 is connected to the Ethernet cable or the video cable, and this part of the wiring harness 7 does not need to be arranged in large quantities. Therefore, the second connector 5 is generally smaller in volume than the first connector 4. It can be seen in the figure that the area of the second installation window 12 is relatively small, and multiple second installation windows 12 can be set in a very small space, so that the Ethernet cable or the video cable can be fixed in the bracket in a centralized manner.
