The third connecting part 402 includes a plurality of third contacts 4021, and the plurality of third contacts 4021 correspond to the plurality of guide rails 3011 one by one and are connected in sliding mode. When the second connecting plate 400 moves relative to the shell 101, the plurality of third contacts 4021 are driven to slide along the corresponding plurality of guide rails 3011.

[0077] In the embodiment, the slide rail part 301 includes a plurality of guide rails 3011, and the third connecting part 402 includes a plurality of third contacts 4021. The plurality of third contacts 4021 correspond to the plurality of guide rails 3011 one by one, that is, one wire harness of the ECU is connected with one pin 104, and the pin 104 is connected with the corresponding first contact 202, second contact 4011, third contact 4021 and guide rail 3011 in a conductive mode. The guide rail 3011 is connected to the rack, so that a signal path is formed between the wire harness of the ECU and the rack, and the performance of the ECU can be tested. The plurality of third contacts 4021 are connected in sliding mode with the plurality of guide rails 3011, so that in the process of movement of the second connecting plate 400 relative to the shell 101, the plurality of third contacts 4021 are driven to slide along the corresponding plurality of guide rails 3011, so as to maintain the signal conduction between the plurality of third contacts 4021 and the plurality of guide rails 3011, and realize stable test.

[0078] Optionally, the number of third contacts 4021 is equal to the number of first contacts 202 of the first connecting part 200. The number of third contacts 4021 is also equal to the number of second contacts 4011, so as to realize the connection of the wire harness of one ECU to the bench.

[0079] In this embodiment, the specific number of third contacts 4021 and guide rails 3011 is not limited and can be designed as needed.

[0080] In combination Figure 3 As shown in the drawings, in some embodiments, the guide rail 3011 is a circular ring. A plurality of guide rails 3011 form a concentric circle structure.

[0081] In this embodiment, the guide rail 3011 is a circular ring, so that the guide rail 3011 has good conductivity and a small friction coefficient. A plurality of guide rails 3011 form a concentric circle structure, that is, a plurality of guide rails 3011 are concentrically arranged, and the radii of a plurality of guide rails 3011 are different, saving installation space, realizing the separate connection of each third contact 4021 and the corresponding guide rail 3011, and facilitating signal transmission.

[0082] In combination Figure 2 As shown in the drawings, in some embodiments, a plurality of first connecting parts 200 are sequentially and spaced arranged along the circumference of the housing 101. The connector 100 further comprises a movable rod 105 and a driving member 106. The movable rod 105 is movably arranged on the housing 101, and the movable rod 105 is fixedly connected with the second connecting plate 400. The driving end of the driving member 106 is connected with the movable rod 105. The driving member 106 is used to drive the movable rod 105 to rotate, thereby driving the second connecting plate 400 to rotate circumferentially relative to the housing 101, so as to connect the second connecting part 401 with one of the plurality of first connecting parts 200.

[0083] In this embodiment, a plurality of first connecting parts 200 are sequentially and spaced arranged along the circumference of the housing 101, that is, a plurality of first connecting parts 200 are sequentially and spaced arranged, and a plurality of first connecting parts 200 are arranged along the circumference of the housing 101.

[0084] In this embodiment, the movable rod 105 is movably arranged on the housing 101, and the movable rod 105 is fixedly connected with the second connecting plate 400, so as to realize that when the movable rod 105 rotates around its own axis relative to the housing 101, the second connecting plate 400 rotates circumferentially relative to the housing 101. The driving end of the driving member 106 is connected with the movable rod 105, so as to drive the movable rod 105 to rotate through the driving member 106, facilitating operation. In this embodiment, the specific manner in which the movable rod 105 is movably arranged on the housing 101 is not limited, for example, the movable rod 105 is bearing arranged on the housing 101, so as to realize that the movable rod 105 can rotate circumferentially around its own axis.

[0085] In the embodiment, the first connecting parts 200 are arranged along the circumference of the shell 101 in sequence and at intervals, and cooperate with the plurality of rails 3011 of the concentric circle structure, so that the second connecting plate 400 rotates smoothly relative to the shell 101, and signal conduction is maintained during rotation.

[0086] Optionally, the driving member 106 comprises a motor, and a driving end of the motor is connected with the movable rod 105 to drive the movable rod 105 to rotate, so that the rotation of the movable rod 105 is automatically controlled.

[0087] Optionally, the driving member 106 comprises a lever. The lever is located outside the shell 101. One end of the lever is connected with one end of the movable rod 105. In actual use, the lever is manually rotated to drive the movable rod 105 to rotate, so that the rotation of the movable rod 105 is manually controlled.

[0088] As a specific example:

[0089] As shown in Figure 1 and Figure 2 , the shell 101 is in a cylindrical structure. The plurality of first connecting parts 200 are arranged on the top of the shell 101. Moreover, the plurality of first connecting parts 200 are arranged along the circumference of the top of the shell 101 in sequence and at intervals, so that the overall volume of the connector 100 is small, and space is saved.

[0090] In the example, as shown in Figure 4 and Figure 5 , the second connecting plate 400 is in a circular structure, so that the second connecting plate 400 rotates smoothly in the accommodating cavity 102 of the shell 101. As shown in Figure 1 , the second connecting part 401 and the third connecting part 402 are located on opposite sides of the second connecting plate 400, respectively. Among them, the second connecting part 401 is close to the first connecting part 200 to facilitate connection with the first connecting part 200. As shown in Figure 1 , the first connecting plate 300 is located on one side of the second connecting plate 400 and close to the third connecting part 402 to facilitate the sliding connection of the sliding rail part 301 and the third connecting part 402. Specifically, the first connecting plate 300 can be fixedly connected with the shell 101. As shown in Figure 3 , the rail 3011 of the sliding rail part 301 is in a circular ring shape, and a plurality of rails 3011 form a concentric circle structure. Since the plurality of third contacts 4021 correspond to and slide with the plurality of rails 3011 one by one, the plurality of rails 3011 form a concentric circle, and therefore, the distance from each of the plurality of third contacts 4021 to the center of the second connecting plate 400 is different, so as to realize the smooth connection of the plurality of third contacts 4021 and the plurality of rails 3011.

[0091] In the example, as shown in Figure 1As shown, the movable rod 105 is connected to the center of the second connecting plate 400 to realize smooth rotation of the second connecting plate 400. The driving member 106 drives the movable rod 105 to rotate, and drives the second connecting plate 400 to rotate relative to the shell 101. At this time, the plurality of second contacts 4011 rotates relative to the shell 101, and the plurality of third contacts 4021 slides along the corresponding plurality of guide rails 3011. When the plurality of second contacts 4011 of the second connecting part 401 rotates to the lower side of the target first connecting part 200, and the plurality of second contacts 4011 abuts against the plurality of first contacts 202 directly above, the second connecting part 401 is connected with the target first connecting part 200, and the ECU connected with the target first connecting part 200 is connected with the rack.

[0092] In this example, when connecting the rack and the plurality of ECUs, the connector 100 can realize simple and convenient installation. When switching the connection of the plurality of ECUs (i.e., only one ECU is in the conductive state with the rack at the same time), the operation process is simple, the switching is smooth and free, and the conduction is good.

[0093] As another specific example:

[0094] The shell is a cuboid structure. The plurality of first connecting parts are arranged on the top of the shell. The plurality of first connecting parts are arranged in sequence along the length direction of the top of the shell.

[0095] In this example, the second connecting part and the third connecting part are respectively located on the two opposite sides of the second connecting plate. Among them, the second connecting part is close to the first connecting part to facilitate connection with the first connecting part. The first connecting plate is located on one side of the second connecting plate and close to the third connecting part to facilitate sliding connection of the sliding rail part with the third connecting part. Specifically, the first connecting plate can be fixedly connected with the shell. The guide rail of the sliding rail part is linear, and the plurality of guide rails are arranged in parallel.

[0096] In this example, the connector also includes a motorized actuator. The motorized actuator is fixed to the housing. The extended end of the motorized actuator is connected to a second connecting plate. The motorized actuator pushes the second connecting plate to move linearly, causing multiple second contacts to move relative to the housing, and multiple third contacts to slide along corresponding guide rails. When the multiple second contacts of the second connecting part rotate to below the target first connecting part, and abut against the multiple first contacts directly above them, the second connecting part is connected to the target first connecting part, thereby enabling the ECU connected to the target first connecting part to conduct with the test bench. When it is necessary to switch the conduction of another ECU to the test bench, the motorized actuator pushes the second connecting plate to move linearly, rotating the multiple second contacts to below the next target first connecting part, and connecting them to the next target first connecting part 200.

[0097] In this example, the connector enables easy installation when connecting the test bench to multiple ECUs. The operation is simple, the switching is smooth and free, and the conductivity is good when switching between multiple ECUs and the test bench (i.e., only one ECU is connected to the test bench at a time).

[0098] Combination Figure 1 and Figure 3 As shown, in some embodiments, the first connecting plate 300 further includes a first circuit board 302 and a first insulating shell 303. One end of the first circuit board 302 is connected to the slide rail portion 301, and the other end of the first circuit board 302 is connected to the stand. The first insulating shell 303 is disposed on the outside of the first circuit board 302.

Figure 1 The wiring harness (indicated by B) is connected to the test bench so that each guide rail 3011 is connected to the test bench, thereby forming a signal path between the ECU wiring harness and the test bench.

[0100] In this embodiment, the first insulating shell 303 is disposed outside the first circuit board 302 to protect the first circuit board 302 and enable normal operation between the components of the connector 100. The slide rail portion 301 is embedded in the surface of the first insulating shell 303, that is, the slide rail portion 301 protrudes from the surface of the first insulating shell 303, so as to enable the slide rail portion 301 to slide smoothly and connect with the third connecting portion 402 for signal transmission, and to achieve insulation between the multiple guide rails 3011, thereby improving safety in use.

[0101] In this embodiment, the material of the first insulating shell 303 is not limited, such as plastic.

The second connecting portion 401 extends out of the second insulating shell 404 to connect with the first connecting portion 200. The third connecting portion 402 extends out of the second insulating shell 404 to be slidably connected with the slide rail portion 301.

[0103] In this embodiment, one end of the second circuit board 403 is connected to the second connecting part 401, and the other end of the second circuit board 403 is connected to the third connecting part 402, so that a signal path is formed between the second connecting part 401 and the third connecting part 402, thereby realizing the formation of a signal path between one of the ECU, the first connecting part 200, the second connecting part 401, the third connecting part 402, the slide rail part 301, and the stand. For example, the second circuit board 403 adopts an integrated circuit board, and multiple second contacts 4011 are connected one-to-one with multiple third contacts 4021 through the integrated circuit, thereby establishing a signal path correspondingly connected between a wiring harness of the ECU, a pin 104 of the connector 103, an interface 201 and a first contact 202 of the first connecting part 200, a second contact 4011 of the second connecting part 401, a third contact 4021 of the third connecting part 402, a guide rail 3011 of the first connecting board 300, and the stand.

[0104] For example, such as Figure 5 As shown, Figure 5 The diagram illustrates that multiple second contacts 4011 and multiple third contacts 4021 are connected in a one-to-one correspondence to achieve signal conduction.

[0105] In this embodiment, the second insulating shell 404 is disposed outside the second circuit board 403 to protect the second circuit board 403 and to enable normal operation between the components of the connector 100. The second connecting portion 401 extends out of the second insulating shell 404 to achieve smooth connection between the second connecting portion 401 and the first connecting portion 200. The third connecting portion 402 extends out of the second insulating shell 404 to achieve sliding connection between the third connecting portion 402 and the slide rail portion 301.
