Abstract

PURPOSE:To reduce initial load by supporting a winding part by a part of the outer circumference laid along the central axis at the time of constituting a support structure for connector contact from a plurally wound coil winding part, and a contact part formed by extending and bending one side end part of the winding part to work it as a torsion spring. CONSTITUTION:The contact pressure P added to the contact part 54b of a connector contact 54 is dispersed into a torsion stress for twisting a coil winding part 54a around the central axis and a slide stress for sliding the winding part 54a vertically to the central axis. Thus, the pressure at initial movement added to a connector socket 16 connected to a multipolar connector plug 18 can be moderated, and the pressure at initial movement added to a video camera 10 is also minimized. The coil winding part 54a is laid in the roughly winding state in non-contact to the adjacent part, whereby the current inputted and outputted from a contact part 541a reaches a terminal part 54c through all the windings of the winding part 54a, and is inputted and outputted from this. Thus, the contact resistance value of the contact 54 is stabilized.

重）が高くなるという問題点があった。However, in the conventional contact supporting structure as shown in FIGS. 9A and 9B, the entire outer circumference of the coil winding portion 54a along the central axis direction is supported. Therefore, the sliding movement in the direction perpendicular to the central axis of the coil winding portion 54a is prohibited. Therefore, the contact portion 54b of the contact 54 when connecting the connector
The contact pressure P applied to the coil acts only as a torsional stress that twists the coil winding portion 54a around the central axis. Therefore, there is a problem that the total load (additional load) at the time of initial movement of the connector connection becomes high.

The present invention has been made in view of the above problems,
It is an object of the present invention to provide a support structure for a contact, which has a simple structure and can reduce an initial load applied to a connector or the like to be connected.

Since it is supported so that it can be twisted by the spring pressing rib 72, the remaining portion (two turns) is twistable and slidable. Therefore, the video camera 10 is connected to the adapter
When the contact pressure P is received from the connector socket 16 of the video camera 10 when placed on the position 2, the contact 54 changes from the state shown in FIGS. 7A and 7B to the state shown in FIG. 7C.

できる。That is, the contact portion 54b of the contact 54
The contact pressure (that is, the load) P applied to is distributed to a torsional stress Ft that twists the coil winding portion 54a around the central axis and a sliding stress Fs that slides the coil winding portion 54a perpendicularly to the central axis. . Therefore, it is possible to reduce the total load at the time of initial movement of the multipolar connector plug. Therefore, it is possible to reduce the initial pressure applied to the connector socket 16 connected to the multi-pole connector plug 18 and reduce the initial pressure applied to the video camera 10.

せることができる。In particular, the direction of the contact pressure P applied to the contact portion 54b of the contact 54 and the arm portion 54 of the contact 54.
When the angle Θ formed by the direction of d is set to an acute angle, the component force acting as a torsion moment on the coil winding portion 54a becomes small, and the total load at the initial movement of the multipolar connector plug is further reduced. It is possible to further relieve the initial pressure applied to the connector socket connected to the multipolar connector plug.

大きな力が加わり負担が大きくなる。That is, in the conventional example shown in FIGS. 9A and 9B, in the coil winding portion 54a of the contact 54, the entire outer circumference (3 windings) along the central axis direction is a columnar support 57. Since it is supported by the support step portion 59 and the slide movement in the direction perpendicular to the central axis is prohibited,
Contact pressure (ie load) applied to the contact portion 54b of the
P is only the torsional stress that twists the coil winding portion 54a. For this reason, the total load at the time of initial movement of the multipolar connector plug becomes high. In the case of a multi-pole connector plug having a large number of poles, the total load applied to the connector socket 16 connected to this multi-pole connector plug 18 at the time of initial movement becomes too large, and a large force is applied to the video camera 10 in which the connector socket 16 is provided and a burden is imposed. growing.

とができる。Since the coil winding portion 54a of the contact 54 is formed in a coarse winding state in which the adjacent portions are not in contact with each other, the current input / output from the contact portion 54b of the contact 54 flows through all the windings of the coil winding portion 54a. Through the terminal 54c,
Input and output is performed from this terminal portion 54c. Therefore, the conductor resistance of the contact 54 can be stabilized, and the contact resistance value of the contact 54 including this conductor resistance can be stabilized.

Since the coil winding portion 53a of No. 3 is formed in a closely wound state in which adjacent portions are in contact with each other, the contact portion 53 of the contact 53 is
The current input from b passes through the portion of the coil winding portion 53a where the contact resistance is low, as shown by the arrow X, and the terminal portion 53c.
And output from this terminal portion 53c. Therefore, the conductor resistance of the contact 53 becomes unstable, and the contact resistance value of the contact 53 including this conductor resistance is not stable.

できる。As described above, the support structure for a connector contact according to the present invention includes a coil winding portion obtained by winding a wire rod in a coil shape a plurality of times, and a coil winding portion for using the coil winding portion as a torsion spring. In a contact for a connector comprising a contact portion formed by extending and bending one end portion, the coil winding portion is configured to support only a part of the outer circumference along the central axis direction, When the contact pressure P is applied to the contact portion of the contact at the time of contact with the connector, this contact pressure (that is, load) P is applied to the coil winding portion by twisting stress Ft that twists the coil winding portion around the central axis. The sliding stress Fs that slides in the direction perpendicular to the central axis can be dispersed. Therefore, it is possible to reduce the total load (load load) at the time of initial movement when the connector is connected.
