However, with this type of bend cable exit plug, during assembly, the terminals are often excessively inserted into the bend. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-core elbow assembly structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-core elbow assembly structure, including a bend and a terminal block; the bend is provided with a snap-fit ​​groove, and the terminal block is adapted to and connected to the snap-fit ​​groove through a snap-fit; the terminal block is also provided with a retaining ring, which abuts against the outer end face of the bend to prevent the terminal block from penetrating into the interior of the bend; a support post is also provided on the inner wall of the bend, which prevents the terminal block from sliding further into the bend.

[0005] As a preferred technical solution of this utility model: the terminal block is further provided with a guide portion; wherein, the guide portion is arranged around the outer wall surface of the terminal block, and the side of the guide portion away from the bend is also provided with a chamfer.

[0006] As a preferred technical solution of this utility model: the bent pipe is further provided with a shaft pin seat, and a locking buckle is rotatably installed on the shaft pin seat. The end of the locking buckle away from the terminal block is connected to a sliding buckle.

[0007] As a preferred technical solution of this utility model: a reinforcing rib is also provided in the wire passage hole below the bend, and the reinforcing rib is distributed at the four corners of the wire passage hole.

[0008] As a preferred technical solution of this utility model: the inner side of the shaft pin seat is further provided with a stepped surface, and the outer side of the sliding buckle is further provided with a stop block, and the stop block slides on the stepped surface.

[0009] As a preferred technical solution of this utility model: a vertical surface is provided on one side of the stepped surface, and a slot is provided on the vertical surface; a pin is also provided on the stop block to be adapted and connected to the slot.

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0015] Please see Figure 1-8 This utility model provides an embodiment of a multi-core elbow assembly structure, including a bend 1 and a terminal block 2; the bend 1 is provided with a snap-fit ​​groove 15, and the terminal block 2 is adapted to and connected to the snap-fit ​​groove 15 through a snap-fit ​​22; the terminal block 2 is also provided with a retaining ring 20, and the retaining ring 20 abuts against the outer end face of the bend 1 to prevent the terminal block 2 from penetrating into the interior of the bend 1; the inner wall of the bend 1 is also provided with a support column 11, and the support column 11 prevents the terminal block 2 from continuing to slide upward into the bend 1.

[0016] In summary, because the terminal block 2 is equipped with a retaining ring 20, it prevents the terminal block 2 from moving excessively into the bend 1 after assembly. Simultaneously, the support column 11 on the inner wall of the bend 1 enhances the overall structural strength of the bend 1 and further prevents the terminal block 2 from moving excessively into the bend. Therefore, since the terminal block 2 will not move excessively during assembly with the bend 1, it ensures smooth assembly and avoids poor contact when the device is plugged into the socket 3 due to the terminal block moving into the bend. Furthermore, the terminal block 2 is also equipped with a guide portion 21; the guide portion 21 is circumferentially disposed on the outer wall of the terminal block 2, and the side of the guide portion 21 away from the bend 1 has a chamfer 23; the chamfer 23 facilitates the insertion of the terminal block 2 into the socket 3.

[0017] Furthermore, after the terminal 2 is inserted into the socket 3, the bend 1 is also provided with a pivot pin seat 13, and a latch 14 is rotatably installed on the pivot pin seat 13. The end of the latch 14 away from the terminal 2 is connected to the provided sliding buckle 12. Therefore, the latch 14 can be used to fasten onto the socket 3 to ensure that the device can be stably and reliably connected to the socket 3. In addition, the locking strength of the latch 14 can be enhanced by the sliding buckle 12 sliding back and forth in the pivot pin seat 13.

[0018] Furthermore, since a reinforcing rib 114 is provided in the wire passage hole below the bend 1, and the reinforcing rib 114 is distributed at the four corners of the wire passage hole, the reinforcing rib 114 can be used to enhance the structural strength of the bend 1.

[0019] Based on the above solution, since the inner side of the pivot pin seat 13 is also provided with a stepped surface 19, and the outer side of the sliding buckle 12 is also provided with a stop block 110, and the stop block 110 slides on the stepped surface 19. Specifically, as follows... Figure 4 and Figure 8 As shown, when the stop block 110 slides to the left on the step surface 19 and then separates from the step surface 19, the sliding buckle 12 is in the locked state of the latch 14. Pressing the sliding buckle 12 down will cause the lock hole on the latch 14 to separate from the locking pin 4 on the socket 3. Conversely, when the lock hole 115 is engaged with the locking pin 4, the sliding buckle 12 at the other end of the latch 14 will be pried up so that the stop block 110 can slide to the right along the step surface 19. At this time, the sliding buckle 12 is located at one end of the latch 14 and always causes the lock hole 115 to be engaged with the locking pin 4.

[0020] Furthermore, since a vertical surface 17 is provided on one side of the stepped surface 19, and a slot 18 is provided on the vertical surface 17; and a pin 111 is provided on the stop block 110 that is adapted to and connected to the slot 18, when the pin 111 is inserted into the slot 18, the position of the sliding buckle 12 is reliably fixed, thereby further improving the locking ability of the sliding buckle 12 to the latch 14.

[0021] Furthermore, since the sliding buckle 12 is also provided with a pin 112 inside, and a spring 16 is fitted on the pin 112, and the other end of the spring 16 is located in the mounting hole 113 provided on the latch 14, the spring 16 can always cause the pin 111 to be inserted into the slot 18 when there is no external force, which can further ensure the locking ability of the sliding buckle 12 to the latch 14.

[0022] In summary, the device and the socket 3 are locked by the latch 14, and then the latch 12 is used to further lock the latch 14. This gives the device and the socket 3 a double locking capability after connection, ensuring a reliable connection between the device and the socket 3 and preventing poor contact due to loosening.

[0023] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
