[0022] See also Figure 1-4The utility model provides a double-ended pluggable electrical connector terminal that is easy to replace, including a terminal housing 1, a first spring 5 and a second spring 6. The terminal housing 1 has an axial length, and a first mounting inner cavity 11 and a second mounting inner cavity 12 are respectively provided at both ends along the axial direction. The first mounting inner cavity 11 includes a first mounting position 111, and the second mounting inner cavity 12 includes a second mounting position 113. The first spring 5 is installed in the first mounting position 111 and is close to the cavity opening of the first mounting inner cavity 11. The second spring 6 is installed in the second mounting position 113 and is close to the cavity opening of the second mounting inner cavity 12. The radial size of the first spring 5 is less than or equal to that of the second spring 6, and the metal density of the first spring 5 is greater than that of the second spring 6. Metal density; the first spring piece 5 is a torsion spring piece, and the second spring piece 6 is a crown spring piece. In this embodiment, the first installation position 111 and the first spring piece 5 are used to plug with the ordinary pin when the connector terminal is installed to the connector, and need to be plugged in and out with the external pin for a long time. Therefore, the metal density of the first spring piece 5 is greater than the metal density of the second spring piece 6, which can form multi-line contact. The high-density metal contact can achieve the characteristics of high connection reliability, soft plugging and unplugging force, strong impact resistance, many plugging and unplugging times and long life, and can better cope with long-term plugging and unplugging; and the second spring piece 6 is a crown spring setting, which makes the contact area larger and the connection more stable. There is no problem of poor contact of the positioning claw and scratching of the male needle head, and the elasticity is difficult to fail.

[0023] In this embodiment, the double-ended mounting cavity incorporates both a torsion spring and a crown spring. The torsion spring inserts into a standard pin, while the crown spring inserts into a riveted cable pin. This structure ensures quick and easy assembly while maintaining performance.

[0024] In one embodiment, the axial depth of the first mounting cavity 11 is greater than the axial depth of the second mounting cavity 12; here, the first mounting cavity 11 needs to be connected to the external pins, so it requires stronger connection adaptability. Under the premise of having a longer depth, it can be adapted to different pin lengths and types. The second mounting cavity 12 is used to connect the pins of the riveted cable, so it requires fewer adaptations and pursues more stability after connection. The smaller depth can save processing costs.

[0025] In one embodiment, the terminal housing 1 is provided with a first positioning hole 2 radially passing through the first mounting inner cavity 11 and a second positioning hole 4 radially passing through the second mounting inner cavity 12; the first positioning hole 2 and the second positioning hole 4 are used to play an anti-mistake positioning function when the terminal housing 1 is installed to the connector. Since the length of the first mounting inner cavity 11 is relatively long, the provision of a through positioning hole structure can ensure the accuracy and stability of positioning under the premise of a large length.

[0026] In one embodiment, the terminal housing 1 is provided with a partition groove 3 cut between the first mounting inner cavity 11 and the second mounting inner cavity 12, and the diameter of the partition groove 3 is smaller than the diameter of other positions of the terminal housing 1; the partition groove 3 also provides an installation and locking function to ensure the axial limitation and positioning function of the terminal housing 1 when it is installed to the connector.

[0027] In one embodiment, a port cover 7 is further included. The outer side wall of the cavity opening of the first installation inner cavity 11 has a thin wall, and the thin wall is provided with a card slot 112. When the first reed 5 is installed in the first installation position 111, the port cover 7 is installed on the first reed 5 and the cavity opening, and is engaged with the card slot 112; the port cover 7 has an arc-shaped surface, and the port cover 7 is integrally formed by stainless steel material; the port cover can better and more stably connect the first reed 5 to the first installation inner cavity 11, and at the same time provide a port protection function to avoid direct failure of the reed during long-term plugging and unplugging. At the same time, the arc-shaped design is more conducive to the rapid insertion of the pin to avoid the pin from hanging.

[0028] Furthermore, the cover made of stainless steel can provide better hardness and thus provide a better service life.

[0029] In one embodiment, the first reed 5 includes multiple first connecting wires 51, and the second reed 6 includes multiple second connecting wires 61. The number of first connecting wires 51 is greater than the number of second connecting wires 61, and the first connecting wires 51 have a spiral structure along the axial direction; the connecting wires provide an area that directly contacts the pin when the pin is inserted. Multiple and denser first connecting wires 51 can be tightly attached to the outer surface of the pin over a larger range, forming multi-line contact with a small contact area, thereby reducing contact resistance and reducing heat.

[0030] In one embodiment, the opening of the second mounting inner cavity 12 has a constricted structure 8 with a reduced diameter. The constricted structure 8 can provide a more stable connection and prevent it from falling out.

[0031] The advantages of this utility model are:

[0032] By setting up a double-ended connector, the end connected to the crimped cable is plugged into the pin of the riveted cable to achieve connection. In this way, there is no need to cut off the crimped cable and re-wrap and rivet it after the terminal fails. The assembly can be completed simply and quickly while ensuring performance.

[0033] The above disclosures are only a few specific embodiments of the present invention, but the present invention is not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
