Their function is very simple: to bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Connectors are indispensable components in electronic devices; following the path of current flow, you will always find one or more connectors. Connector forms and structures are incredibly diverse, varying depending on the application, frequency, power, and environment.

[0003] As disclosed in patent publication number CN219610828U, a waterproof cable connection cap structure for a connector includes a connector sleeve and a tail cap that detachably engages with the connector sleeve. The tail cap includes a tail cap sleeve and a cap end wall with a through hole for the cable to pass through. An annular cavity is formed between the connector sleeve and the cap end wall. A limiting annular sealing structure is provided within the annular cavity, and several sealing ring protrusions are provided on the inner wall of the annular sealing structure. However, the connector sleeve is prone to rotation under stress, causing the connector to loosen and thus affecting the normal transmission of signals, ultimately resulting in poor signal quality. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a tail cap locking structure for circular stamped terminals.

[0005] The objective of this utility model is achieved through the following technical solution: A tail cap locking structure for a circular stamped terminal includes a housing and a terminal. The housing is cylindrical, and its end face has a hole with the same diameter as the insertion end of the terminal. The housing has a positioning plate inside, and the positioning plate has a positioning groove with a contoured design for the connection end of the terminal. The connection end is placed in the positioning groove, and a circumferential limiting component is provided between the connection end and the positioning plate to limit the circumferential rotation of the connection end. A tail cap is engaged on the side of the housing away from the end face, and an axial limiting component is provided between the tail cap and the connection end to limit the axial movement of the connection end.

[0006] Preferably, the circumferential limiting component includes a positioning groove formed on the inner wall of the positioning plate, the central axis of the positioning groove being parallel to the central axis of the connecting end; a positioning head adapted to the positioning groove is fixed on the outer circumferential surface of the connecting end, the positioning head being placed in the positioning groove and closely attached to the end face.

[0007] Preferably, the axial limiting component includes a limiting plate fixed on the tail cap, the limiting plate having a limiting groove, and a limiting head adapted to the limiting groove fixed on the connecting end; when the tail cap is engaged with the housing, the limiting head is placed in the limiting groove, one end of which abuts against the end face, and the other end abuts against the limiting plate.

[0008] Preferably, the housing is further provided with a support plate, and the support plate has a receiving groove that matches the outer contour of the outer wall of the limiting plate.

[0009] Preferably, a reinforcing rib fixed to the end face is provided between the support plate and the positioning plate.

[0010] Preferably, symmetrically arranged locking blocks are fixed on the outer circumferential surface of the housing, and the tail cap is provided with a locking groove that matches the locking blocks.

[0011] Preferably, the locking block is in the shape of a right-angled trapezoid, and when the tail cap is engaged with the housing, the right-angled surface of the locking block abuts against the tail cap.

[0012] The beneficial effects of this utility model are mainly reflected in: 1. The design is ingenious. The positioning head and the limiting head work together to restrict the axial and circumferential movement of the terminal within the housing, preventing the housing from rotating relative to the terminal when under force, thus ensuring the stability of the structure and ensuring that the signal is always transmitted normally.

[0013] 2. The support plate supports the limiting plate, preventing it from deforming under long-term gravity and extending its service life.

[0014] 3. The addition of reinforcing ribs can enhance the overall structural strength and rigidity of the stamped terminals.

[0015] 4. The insertion between the housing and the tail cap is achieved through the cooperation of the locking block and the locking slot. This insertion method is stable and reliable, and is easy to disassemble, replace and maintain, which greatly improves work efficiency. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 5 As shown, this utility model discloses a tail cap locking structure for a circular stamped terminal, including a housing 1 and a terminal 2. The housing 1 is cylindrical, and its end face 10 is provided with a socket 11 with the same diameter as the plug end 20 of the terminal 2. The plug end 20 passes through the socket 11 and is connected to a cable.

[0022] The housing 1 has a built-in positioning plate 12, on which a positioning groove 13 is formed by the contour design of the connecting end 21 of the terminal 2. The connecting end 21 is placed in the positioning groove 13, and a circumferential limiting component is provided between the connecting end 21 and the positioning plate 12 to limit the circumferential rotation of the connecting end 21. The circumferential limiting component includes a positioning groove 14 formed on the inner wall of the positioning plate 12, the central axis of the positioning groove 14 being parallel to the central axis of the connecting end 21; a positioning head 22 adapted to the positioning groove 14 is fixed on the outer circumferential surface of the connecting end 21, the positioning head 22 being placed in the positioning groove 14 and in close contact with the end face 10.

[0023] A tail cap 3 is fitted onto the side of the housing 1 away from the end face 10. An axial limiting component is provided between the tail cap 3 and the connecting end 21 to restrict the axial movement of the connecting end 21. The axial limiting component includes a limiting plate 31 fixed to the tail cap 3, with a limiting groove 32 formed on the limiting plate 31. A limiting head 23 adapted to the limiting groove 32 is fixed on the connecting end 21. When the tail cap 3 is engaged with the housing 1, the limiting head 23 is placed in the limiting groove 32, with one end abutting against the end face 10 and the other end abutting against the limiting plate 31. This ingenious design, with the positioning head 22 and the limiting head 23 cooperating to restrict the axial and circumferential movement of the terminal within the housing, prevents the housing from rotating relative to the terminal under force, thereby ensuring the stability of the structure and ensuring that the signal is always transmitted normally.

[0024] In this invention, the positioning head 22 and the limiting head 23 are integrally formed with the terminal 2, which can reduce the processing difficulty, greatly improve the work efficiency, and has a wide range of applicability.

[0025] The housing 1 also includes a support plate 15, which has a receiving groove 16 that matches the outer contour of the outer wall of the limiting plate 31. The limiting plate 31 rests on the support plate 15, which supports the limiting plate 31 to prevent deformation under long-term gravity and extend its service life. Furthermore, a reinforcing rib 17 is fixed to the end face 10 between the support plate 15 and the positioning plate 12, which enhances the strength and rigidity of the structure.

[0026] Symmetrically arranged locking blocks 18 are fixed on the outer circumference of the housing 1. The tail cap 3 has a locking groove 33 that matches the locking blocks 18. The locking blocks 18 are in the shape of a right-angled trapezoid. When the tail cap 3 is engaged with the housing 1, the right-angled surface of the locking blocks 18 abuts against the tail cap 3. The engagement between the housing 1 and the tail cap 3 is achieved through the cooperation of the locking blocks 18 and the locking groove 33. This engagement method is stable and reliable, facilitates disassembly, replacement, and maintenance, and greatly improves work efficiency.

[0027] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0028] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
