Description

Technical Field

[0001] This utility model relates to a 14-pin connector. Background Technology

[0002] A 14-pin connector is an electrical connection device with 14 contacts for connecting circuit conductors or transmission elements to enable the transmission of current or signals. Its primary function is to establish a connection at the point of circuit interruption or between isolated circuits, ensuring the normal operation of the electrical system. This type of connector is typically used in applications requiring high reliability and stability.

[0003] A typical 14-pin connector is secured by a button after connection. Existing button structures use connecting strips fixed on both sides of the pressing plate, aligned with the extension direction of the main body, to control the engagement or disengagement of the latch and the locking block. However, to avoid affecting the twisting of the pressing plate, the connecting strips are usually quite long. This results in a lower number of presses that the connecting strips can withstand and a lower strength, making them unable to withstand excessive twisting, leading to button damage and a shorter lifespan.

The inner wall of the mounting hole (12) facing the insertion end of the first mounting block (11) and the inner wall of the second mounting hole (22) facing the insertion end of the second mounting block (21) are both provided with limiting ring grooves (7) that allow one end of the spring piece (6) to extend outward to enter and form a limiting fit. The male terminal block (231) and the female terminal block (131) are respectively limited in the first mounting hole (12) and the second mounting hole (22) through the limiting ring groove (7) and the limiting fit of the spring piece (6).

5. A 14 -way connector according to claim 4, wherein: The inner wall of the first mounting hole (12) facing the connecting end of the first mounting block (11) and the inner wall of the second mounting hole (22) facing the connecting end of the second mounting block (21) are both provided with concave annular grooves (8). The concave annular groove (8) in the first mounting hole (12) can contact the female end connecting block (134), and the concave annular groove (8) in the second mounting hole (22) can contact the male terminal connecting block. The female terminal assembly (13) is connected through the female terminal block (131). The spring piece (6) on the male terminal block (231) is limited to the female terminal block (134) by the limiting engagement of the spring piece (6) on the male terminal block (231) with the limiting engagement of the limiting ring groove (7) and the concave ring groove (8) in the second mounting hole (22). The male terminal block (23) is limited to the female terminal block (134) by the contact of the spring piece (6) on the male terminal block (231) with the limiting ring groove (7) and the concave ring groove (8) in the second mounting hole (22).

6. A 14-lead connector as defined in claim 1, wherein: The outer wall of the second mounting block (21) is fixedly provided with an outer plate (213) to facilitate the installation of the second mounting block (21). The outer plate (213) is provided with multiple positioning holes, and each positioning hole is fixedly provided with an embedded nut (9). The socket assembly (2) is quickly installed and fixed with the external bolts through the embedded nut (9). A waterproof gasket (10) is fixedly provided on the outer plate (213).

7. A 14-lead connector according to claim 6, wherein: A multi-layer sealing ring (111) is fitted on the outer wall of one end of the insertion end of the first mounting block (11). The multi-layer sealing ring (111) is located between the first mounting block (11) and the surrounding plate (31). The multi-layer sealing ring (111) acts on the inner wall of the groove on the side facing the surrounding plate (31).

8. A 14-lead connector as defined in claim 6, wherein: Waterproof plugs are provided inside the connecting end of the first mounting hole (12) and inside the connecting end of the second mounting hole (22). The middle part of the waterproof plug is connected. The waterproof plugs in the first mounting hole (12) and the waterproof plugs in the second mounting hole (22) are connected to the corresponding first mounting hole (12) and second mounting hole (22).
