Description

Technical Field

[0001] The utility model relates to the technical field of terminal connectors, in particular to a terminal connector with low matching force and high stability. Background Art

[0002] Terminals are components that connect batteries to external conductors. Terminals are mainly used to transmit electrical signals or conduct electricity. Terminals are connected and fixed by terminal connectors.

[0003] After searching, the application with patent number 202320964135.4 discloses a terminal connector with good stability, including a female side of a terminal, a male side of a terminal, a first positioning shell and a second positioning shell. The two first positioning shells of the two terminal connectors are provided with pressing grooves on the sides away from each other, and a pressing rod is slidably connected in the pressing groove of the terminal connector. One end of the pressing rod of the terminal connector located inside the first positioning shell is fixedly connected to a U-shaped movable plate, and two vertical plates of the U-shaped movable plate of the terminal connector are fixedly connected to a limiting rod, and the other side of the U-shaped movable plate of the terminal connector away from the pressing rod is fixedly connected to two springs;

[0004] Although the terminal connector with good stability pushes the U-shaped movable plate and the limit rod inside the first positioning shell back together by squeezing the pressing rod, and inserts the positioning plate into the first positioning shell, when the pressing rod is released, the two springs will push the two limit rods to be inserted into the limit grooves for limiting, but there is a gap between the contact surfaces of the female side and the male side of the terminal connector with good stability, and external water and dust can easily enter the gap, and then the terminal is damaged.

[0005] Therefore, we propose a terminal connector with small matching force and high stability. Utility Model Content

The terminal pins have the same specifications as the terminal jacks, and a sealing gasket is movably sheathed on the outer side of the boss, and the bottom surface of the sealing gasket is in contact with the top surface of the male side of the terminal.

[0009] Preferably, the sealing gasket is made of silicone, the boss is movably mounted inside the plug-in groove, and the terminal pin is movably mounted inside the terminal socket, wherein when the female side of the terminal and the male side of the terminal are connected together, the contact surfaces of the female side of the terminal and the male side of the terminal will squeeze the sealing gasket, and then the sealing gasket will fill the gap between the female side of the terminal and the male side of the terminal, thereby preventing external water and dust from entering the gap between the female side of the terminal and the male side of the terminal.

[0010] Preferably, an upper connecting plate is fixedly installed in the middle of the bottom ends of the left and right sides of the female side of the terminal, and a through hole is provided on the top surface of the upper connecting plate. A lower connecting plate is fixedly installed in the middle of the top ends of the left and right sides of the male side of the terminal, and a threaded hole is provided on the top surface of the lower connecting plate opposite to the position of the through hole, wherein the provision of the through hole and the threaded hole facilitates the upper connecting plate and the lower connecting plate to be connected together.

When plugging and unplugging the female side and the male side of the terminal, the fingers come into contact with the anti-slip strips, and the friction between the anti-slip strips and the fingers is relatively large, making it easier to save effort when plugging and unplugging the female side and the male side of the terminal.

[0014] The utility model provides a terminal connector with low matching force and high stability. It has the following beneficial effects:

[0015] 1. This pair of low-force and high-stability terminal connectors squeezes the sealing gasket through the female side and the male side of the terminal, and then fills the sealing gasket in the gap between the female side and the male side of the terminal, thereby preventing external water and dust from entering the gap between the female side and the male side of the terminal, which is beneficial to increasing the sealing of the contact surface between the female side and the male side of the terminal, and is beneficial to protecting the inside of the female side and the male side of the terminal, thereby increasing the service life of the female side and the male side of the terminal, and solving the problem that there is a gap between the contact surfaces of the female side and the male side of the terminal in the existing device, and external water and dust are easy to enter the gap, thereby damaging the terminal;

[0016] 2. This pair of low-force and high-stability terminal connectors drives the threaded rod to rotate through the knob, and then the bottom end of the threaded rod passes through the through hole on the upper connecting plate and then is threadedly sleeved inside the threaded hole, so that the upper connecting plate and the lower connecting plate can be connected together, and then the female side of the terminal and the male side of the terminal are connected together, which increases the stability of the connection between the female side of the terminal and the male side of the terminal;

[0017] 3. This pair of low-force and high-stability terminal connectors has rectangular grooves and anti-slip strips. When plugging and unplugging the female side and male side of the terminal, the fingers come into contact with the anti-slip strips, and the friction between the anti-slip strips and the fingers is relatively large, making it easier to plug and unplug the female side and male side of the terminal.
