[0049] The following detailed description of the present invention will make the features and advantages of the present invention more clear and explicit.

[0050] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0051] Embodiment 1:

[0052] like Figure 1 , Figure 2 and Figure 3 The present invention discloses a reusable quick-connect bus cable connector, comprising an outer shell 1, a conductive inner shell 2, an inner cavity outer shell 3, an insulating inner cavity 4, a slider pin 5, a duck tongue copper sheet 6, a conductive sheet 7, an insulating limit column 8, an inner shell cover 9, an outer shell cover 10, a left compression spring 11, a right compression spring 12, an end cover plate 13, a wire pressing column 14, a cover plate screw 15 and a handle screw 16;

[0053] Weld the two conductive sheets 7 to the core of the bus cable 17, such as the blue and white wire in the 1553B bus cable, and pass the bus cable 17 through the insulating limit column 8, the inner shell cover 9, the right compression spring 12 and the outer shell cover 10. Then, assemble the two conductive sheets 7 together with the two slider pins 5 and the two duck tongue copper sheets 6 into the insulating inner cavity 4 at the same time, and then insert the whole into the inner cavity outer shell 3. Push the above-assembled parts into the conductive inner shell 2 as a whole, use the insulating limit column 8 to press the above-assembled parts to the left as a whole, and then lock them through the inner shell cover 9. The inner shell cover 9 is threadedly connected to the right end of the conductive inner shell 2. The purpose of this is to ensure that the position of the inner cavity outer shell 3 relative to the conductive inner shell 2 remains unchanged, and the shielding layer of the bus cable is welded to the inner shell cover 9. Install the above-assembled parts into the outer shell 1 as a whole, install the right compression spring 12 and the outer shell cover 10 at the right end, and make the outer shell cover 10 threadedly connected to the right end of the outer shell 1. The left end of the outer shell 1 is loaded with a wire pressing post 14 , a left compression spring 11 and an end cover 13 , and finally the handle screws 16 on both sides of the conductive inner shell 2 are tightened, and the end cover 13 is fixedly connected to the left end of the outer shell 1 through four cover screws 15 .

[0054] When the component test needs to transfer the bus cable, the above cable connector structure is used to improve the efficiency and stability of the linear coupler component test and reduce the test cost while meeting the premise of stable electrical performance connection. The specific usage method is as follows:

[0055] While holding the column outer shell cover 10, pull the two handle screws 16 with your fingers, and the handle screws 16 drive the conductive inner shell 2 and the internal parts to move as a whole. Figure 1 As shown, the left side of the conductive inner shell 2 moves to the right, and at the same time, the conical surface at the left end of the conductive inner shell 2 is separated from the flare at the right end of the crimping post 14. The end of the cable of the product to be tested is processed to expose the shielding layer and the core of the cable of the product to be tested to a suitable length, and then the cable of the product to be tested is inserted from the left end of the cable connector, and the blue and white cores of the cable of the product to be tested are ensured to pass through the wire hole at the left end of the conductive inner shell 2 through the observation window of the outer shell 1. After the shielding layer of the cable of the product to be tested reaches the conical surface at the left end of the conductive inner shell 2, it is stretched open by the conical surface, and the two handle screws 16 can be loosened at this time. After loosening the two handle screws 16, the elastic force of the right compression spring 12 pushes the inner shell cover 9, causing the conductive inner shell 2 to move to the left as a whole. At the same time, the elastic force of the left compression spring 11 causes the conical surface at the left end of the conductive inner shell 2 to cooperate with the bell mouth at the right end of the wire pressing post 14, thereby pressing the cable shielding layer of the product to be tested. With the help of the closed continuity of the conductive inner shell 2, the cable shielding layer of the product to be tested and the shielding layer of the bus cable 17 form a better connection, thereby improving the electromagnetic shielding of the entire connector. The materials used for the conductive inner shell 2 and the inner shell cover 9 are all conductive materials, and the cylindrical surface of the conductive inner shell 2 is continuous and complete. The overall leftward movement of the conductive inner shell 2, the inner cavity outer shell 3 and the insulating inner cavity 4 will also cause the left ejector pin of the slider 5 to contact and squeeze with the annular boss inside the outer shell 1. At this time, the slider ejector pin 5 will move to the right relative to the inner cavity outer shell 3, from Figure 3It can be seen that the rightward movement of the slider pin 5 will squeeze the duck tongue copper sheet 6, causing it to deform and then squeeze and lock the blue and white cores of the cable of the product to be tested together with the conductive sheet 7, thereby ensuring the stability of the electrical performance connection between the cable of the product to be tested and the bus cable. After the test of the product to be tested is completed, hold the outer shell cover 10 and pull the two handle screws 16 with your fingers to separate the conical surface at the left end of the conductive inner shell 2 from the flared mouth at the right end of the wire pressing column 14, thereby releasing the pressure on the shielding layer. At the same time, due to the resilience of the duck tongue copper sheet 6, the slider pin 5 will move left, separating the duck tongue copper sheet 6 from the conductive sheet 7 and unlocking the locking pressure on the blue and white cores of the cable of the product to be tested. At this time, you can directly pull out the cable of the product to be tested and replace it with another cable of the product to be tested for a new round of testing.

[0056] The advantage of the present invention is that the right compression spring 12 applies a leftward elastic force to the inner shell cover 9, thereby pushing the conductive inner shell 2, the inner cavity outer shell 3, the insulating inner cavity 4 and other components to move to the left as a whole, and at the same time, the left compression spring 11 applies a rightward elastic force to the wire pressing post 14, so that the conical surface at the left end of the conductive inner shell 2 and the bell mouth at the right end of the wire pressing post 14 press the shielding layer of the cable of the product to be tested, and with the help of the closed continuity of the conductive inner shell 2, the shielding layer of the cable of the product to be tested and the shielding layer of the bus connection cable form a good connection to improve the electromagnetic shielding of the entire connector. The overall leftward movement of the conductive inner shell 2, the inner cavity outer shell 3, the insulating inner cavity 4 and other components will cause the left side ejector of the slider ejector 5 to contact and squeeze with the internal boss of the outer shell 1, at this time, the slider ejector 5 will move to the right relative to the inner cavity outer shell 3, and the rightward movement of the slider ejector 5 will squeeze the duck tongue copper sheet 6, causing it to deform and then squeeze and lock the blue and white wire core of the cable of the product to be tested together with the conductive sheet 7, thereby ensuring the stability of the electrical performance connection between the cable of the product to be tested and the bus cable. The present invention is simple and quick to operate. It only requires pulling the handle screw 16 and then inserting the cable of the product to be tested to quickly complete the cable connection operation. Moreover, the present invention can be reused.

[0057] The present invention has been described in detail above in conjunction with specific implementations and exemplary examples, but these descriptions cannot be understood as limiting the present invention. Those skilled in the art understand that, without departing from the spirit and scope of the present invention, a variety of equivalent substitutions, modifications or improvements may be made to the technical solution of the present invention and its implementation methods, all of which fall within the scope of the present invention.
