Description

[Detailed description of the invention] The present invention relates to a connector for making electrical connections.

More specifically, the present invention relates to a connector that maintains good contact by applying vibration to the contact portion.

The production volume of connectors has increased significantly due to the modularization of electrical equipment and the convenience of replacing parts during maintenance.However, connectors are parts that touch surfaces. Due to gas contamination and oxidation on the contact surface of the nib, its uneven S
Therefore, conventionally, the surface of the contact part is plated with a precious metal to prevent oxidation. However, in consideration of the wear caused by insertion and removal of the connector, must be given a thickness of

This refined precious metal GL! In addition, in order to maintain the contact stability f, the contact force must be large (11[
f: Must be secured. As a result, the frictional force at the contact portion also increases. With multi-pole connectors, the insertion and removal force is so large that it is difficult to remove the connector with one hand.

As a countermeasure for this, after inserting the connector, separately
There is a so-called zero-in surge connector that has an S-swinging mechanism and an S-swinging action, but there is a problem in that the structure is complicated.Furthermore, in order to ensure sufficient contact force, the stress of the spring material must be increased. The design constraints are that it must be made of strong material and have a certain maximum size, and miniaturization.
f: The size of the connector is 9! ! I tend to be.・The misfire #4 is a connector that performs electrical W! connection, with the aim of solving such conventional problems and providing a compact, low-cost connector that has high glability. Some parts have Kaii mechanical organs,
It is characterized by being able to apply vibration to the contact part.

Here, when comparing the contact load with a relay, which is the same contact part as a connector, even though the contact part is the same, a relay has a light load after Sgrll, whereas a connector has a normal load of 100 gr or more.〇This difference is common. is also the difference of the required value fI of 4 degrees, but in the case of a relay, due to the collision of the contact part due to the contact operation and the continued vibration of the spring, the contact direction slides slightly, and the film on the surface of the contact S is broken, resulting in a smooth contact. It is thought that this difference is caused by the fact that

Unexploded Q11#i The above points are worth mentioning, and even in the case of 60 connectors, if a smooth contact surface is restored by occasionally improving the sliding, the contact force itself must be maintained. Considering this, I will write the following example below to explain the present invention in detail! In this figure, 1 is a contact, 2 is a piezoelectric element, 8 is a printed board, 2 is a support material, and the arrow is the perturbation direction of the piezoelectric element.

Note that in this figure, the electrodes of the piezoelectric element and the connector housing are not shown.

In this embodiment, a piezoelectric element 2 is incorporated as a mechanical vibrator into a part of a connector housing in which a contact l formed by a spring that provides a contact force is molded.

As a result of its expansion and contraction, the contact surface vibrates after M'll and the contact area slides, the contact surface is restored and a good contact is maintained. In addition, in the part where the support number is attached, the spring material is entirely bent into a chevron shape to allow forward and backward movement. , the amplitude becomes larger and the sliding becomes larger.

FIG. 2 shows an embodiment of the pond of the present invention, which is a part of the contactor. In this figure, 5 is a twin contact, 6 is a piezoelectric element, and 7
indicates support material.

In this embodiment, the spring is folded back nine times at the tip to form a twin contactor 5.
A piezoelectric element S applies longitudinal vibration to the folded portion. Due to this arrangement, the contact 5 becomes a kind of Eden spring, and its tip moves in the horizontal direction with an expanded amplitude.

Therefore, a sufficient sliding amplitude can be obtained and good contact can be maintained even with a small contact force.

Figure 8 shows another embodiment of the present invention. In this figure, 8 is a support material, 9 is a piezoelectric element, 10 is a contact, 11 is a plug,
The fracture layer indicates the displacement of the contact.

In this embodiment, a spring curved in a chevron shape is used as the contact 10, and this is caused to vibrate in a one-dimensional vibration mode with the edge tip directed to the piezoelectric element 9 and the base fixed. l is displaced as shown by the broken line and slides on the contact surface with the plug 11 in the direction of the arrow to maintain good contact.The above embodiment applies the present invention to a printed board connector and is a hole type. However, the present invention is not limited to this 't'L, but the present invention is a connector Kji port JtrH for making all kinds of electrical connections.

In addition to piezoelectric elements, there are currently various types of small mechanical vibrators such as ASS products such as fly strain type vibrators, which can be easily incorporated into a part of a gold connector. Furthermore, the cost of adding brass implants to electronic equipment is not so high anymore.
For example, when the device starts operating, it first applies vibration to the contact part,
l! Functions such as adding vibration to try to recover when a touch failure occurs are easy to add or are a waste of time.As explained above, and according to the uninvention, contact reliability is improved.
In addition, it is possible to reduce the contact force, reduce the thickness of the precious metal film, and increase the spring length to 951M, making the connector smaller and cheaper.
