Abstract

PURPOSE:To stabilize contact resistance against the applied external pressure or the change of the external pressure direction by bringing a moving terminal into elastic contact with a contact fin via the gap between the inner diameter of a rod-like member and the moving terminal outer shape smaller than the inner diameter. CONSTITUTION:When a moving terminal 7 is stored in a conducting contact pin 1, a contact fin 14 provided in the pin 1 is brought into pressure contact with the terminal 7. Even if some external pressure P is applied to the terminal 7 from any direction, the fin 14 is invariably kept in contact with the pin 1 because of its elasticity. The partial pressure generated on a plate-like elastic body deformed into a bow shape by pressing acts to keep the terminal 7 in contact with the pin 1. The terminal 7 is brought into elastic contact with the contact fin 14 via the gap of the moving terminal outer shape smaller than the inner diameter of a rod-like member 2, and stable contact resistance is obtained.

FIG. 7 is a graph showing the variation result of the contact resistance value when an instantaneously varying external pressure is constantly applied to a movable terminal of a conventional spring connector having such a structure for a certain period of time. In the figure, 1 is a lower limit value indicating a stable contact resistance in a conductive state, 2 is an upper limit value indicating a maximum fluctuation range of the contact resistance value, and 3 is a fluctuation range. In the conventional spring connector, when the movable terminal 7 slides in the conductive contact pin 1, the movable terminal and the conductive contact pin do not always maintain the contact state, and as a result, the conductive path is from the movable terminal to the coil spring. A first electrical path in which a path that leads to the contact pin via the movable terminal and a path that directly leads from the movable terminal to the contact pin are connected in parallel, and a second electrical path that leads from the movable terminal to the contact pin via the coil spring are configured. . As described above, when the second electric path is formed, the resistance value becomes much larger than that in the case of the first electric path. The state is shown in FIG. 7 as the stable contact resistance value 1 and the fluctuation range 3 You can understand by comparing. Further, the external pressure applied to the movable terminal and the direction of the external pressure change instantaneously, and as a result, the contact pressure between the movable terminal and the conductive contact pin fluctuates, and the first electric path and the second electric path are extremely short-term. In the situation where it switches to
Noise as shown by 4 in FIG. 7 is generated.

Since the conventional spring connector is constructed as described above, the contact state between the movable terminal and the conductive contact pin cannot always be maintained in a stable state, and therefore the movable connector is not movable. There is a problem that a plurality of conductive paths having different electric resistances are formed between the terminals and the conductive contact pins. In addition, a change in the external pressure applied to the movable terminal in an instant or a change in the direction of the external pressure changes the contact pressure between the movable terminal and the conductive contact pin, thereby forming a plurality of conductive paths, which is extremely short-term. If these conductive paths having different electric resistances are switched to each other, there is a problem that noise may be generated in the signal line.

In the second embodiment, no spiral is provided at the contact end between the coil spring 10 and the movable terminal 7, and the spiral terminal 15 is used. Reference numeral 20 denotes a contact point between the movable terminal 7 and the conductive contact pin 1, and here, the portions denoted by the same reference numerals as in the conventional example indicate the same or corresponding portions. Next, the operation will be described. The contact end between the coil spring 10 and the movable terminal 7 has a spiral end 15

Embodiment 4. Hereinafter, a fourth embodiment of the present invention will be described with reference to FIG. In the figure, 18 is formed coaxially with the coil spring 10, and is provided with a conduction spring for stabilizing the electrical connection between the conduction contact pin and the movable terminal by applying a resistance lowering treatment such as gold plating, This is a guide for preventing the coil spring 10 and the conduction spring 18 from being entangled. Also, the parts given the same reference numerals as in the conventional example indicate the same or corresponding parts. Next, the operation will be described. By incorporating a conduction spring, the movable terminal 7 is connected to the conduction contact pin 1
As a conduction path up to, a first pattern directing from the movable terminal 7 to the conduction contact pin 1 as shown in FIG. 4A, and a conduction spring 18 and a coil spring from the movable terminal 7 as shown in FIG. 4B. A second pattern is conceivable, which goes through 10 to the conductive contact pin. Here, if the conduction spring resistance value in the case of the second pattern is R1 and the resistance value of the coil spring is R2, the total resistance value R is R =
It becomes R1R2 / (R1 + R2). Coil spring R
2 has a large resistance value and the conduction spring R1 has a very small resistance value, so that the total resistance value R becomes very small. Therefore, even if the switching between the two conductive path patterns occurs, the change of the contact resistance value becomes very small. Also,
Considering that a large deflection load of the spring affects the movement of the movable terminal, the conduction spring is built in to reduce the resistance value.
The smaller the deflection load of the conduction spring, the more desirable.

As described above, according to the first aspect of the present invention, the movable terminal and the conductive contact pin are pressed by the elastic contact fins formed integrally with the conductive contact pin. There is an effect that a stable spring connector can be obtained. According to the second aspect of the invention, the contact ends of the coil spring and the movable terminal are matched with the terminal shape of the coil spring, so that the movable terminal presses the partial pressure generated with respect to the spring pressure to the conductive contact pin. It is possible to work in any direction, and the same effect as the first aspect of the invention can be obtained. Further, according to the third aspect of the invention, since the plate-shaped elastic body is provided, a partial pressure is generated in the direction in which the movable terminal presses the conductive contact pin on the plate-shaped elastic body that is deformed into an arc shape by pressing. It is possible to achieve the same effect as the first invention. Further, according to the fourth aspect of the invention, since the conductive spring having a low electric resistance value is provided in addition to the coil spring, there is an effect that a spring connector having a low contact resistance value can be obtained.
