[Industrial applications]

The present invention relates to a means for mounting a connector for connecting units to a chassis or the like, and more particularly to a connector mounting structure for improving productivity by mounting the connector on a chassis or the like so as to enable automatic assembly between units.

With the recent trend of automation, automation has been adopted in assembling various devices.

For example, two units each having a plug side and a jack side of a connector attached thereto may be automatically connected at the plug and the jack part to assemble a device or the like. If there is a shift, reliable connection may be impaired or the connector may be damaged. Therefore, means for absorbing the position shift is required.

[Conventional technology]

FIG. 2 is a view for explaining an example of a conventional connector mounting method.

In FIG. 2, a jack terminal side (not shown) of a multi-core connector (hereinafter simply referred to as a connector) on a chassis 1 of the first unit is exposed to the outside (the lower side in the figure) of the first unit. And a nut 3 with a flange.

2a indicates a connection terminal connected to the internal circuit of the first unit, which is integrated with the jack terminal.

A connector plug 12 is mounted on the chassis 11 of the second unit with a screw 13 and a flanged nut (not shown) so that the plug terminal 12a side is exposed to the outside (upper side in the figure) of the second unit. I have.

Reference numeral 12b in the figure denotes a connection terminal connected to the internal circuit of the second unit, which is integrated with the plug terminal 12a.

In particular, the plug 12 in this case has a protruding plug terminal 12a.
The four sides of the area where the plug terminals 12a are planted are so as not to bend or break due to external force.
Surrounded by

In the plug 12 shown in the drawing, the vicinity of both wall surfaces facing in the longitudinal direction of the housing wall 12c (the range shown by A in the drawing) is the plug.
A taper 12d that opens to the opening side is provided on the opening side so as to serve as a guide when the housing 2b surrounding the jack terminal (not shown) of the jack 2 fitted with the jack 12 is inserted.

Therefore, for example, the first unit, in other words, the chassis 1 is lowered as shown by an arrow a by an assembling automatic machine (not shown) having the first unit, and the housing 2b of the jack 2 is connected to the housing wall 12c of the plug 12. When the jack 2 and the plug 12 are inserted into the region surrounded by the, the first unit and the second unit can be connected.

In this case, if the relative displacement between the first unit and the second unit is, for example, about 1 mm or less, the displacement is guided by the taper 12d provided on the housing wall 12c of the plug 12. Can be absorbed and both can be reliably connected.

On the other hand, if the displacement is larger than the above value, for example, the guide cannot be completely absorbed by the guide by the taper 12d, and as a result, complete connection cannot be achieved or the housing wall 12
c will be damaged.

Therefore, conventionally, for example, the chassis 11 on the second unit side is used.
The first unit is lowered in a state where the screw 13 is loosened so that the plug 12 can move with respect to the chassis 11, and the plug 12 with respect to the chassis 11 when the plug 12 and the jack 2 are fitted to each other. By determining the position, automatic assembly by the subsequent automatic machine is performed.

[Problems to be solved by the invention]

According to the conventional connector mounting method, when applied to automatic assembly by an automatic machine, the relative positional relationship between the two units to be connected must be checked in advance, so that it takes a lot of man-hours, and improvement in productivity cannot be expected. There was a problem.

[Means for solving the problem]

The above-described problem is caused by a plug having a plug housing wall surrounding a plug terminal arrangement area at a height exceeding the plug terminal and a mounting hole to a chassis, and a housing fitted to an inner surface of the plug housing wall. A connector for mounting a connector comprising a jack having a jack terminal embedded therein between chassises, wherein the plug mounted on one chassis has an outer diameter smaller than the diameter of the mounting hole and a length equal to the length of the mounting hole. The other chassis which is screwed to the chassis via a sleeve slightly exceeding the sum of the hole length and the thickness of the chassis and is mounted so as to be floatable in a two-dimensional direction parallel to the chassis, and to which the jack is mounted, is mounted on the other chassis. In a region corresponding to the plug housing wall on the plug side, there is provided a tongue-shaped plug position correcting tool for moving the plug to a predetermined position by contact with the plug housing wall based on the approach of the plug. It was solved by mounting structure of the inter-chassis connector.

[Action]

If the plug (jack) side of the connector is attached to the unit so that it can float in a plane orthogonal to the fitting direction, the relative displacement of the jack (plug) within the floating amount range can be absorbed.

In the present invention, for example, the plug is inserted through a sleeve whose outer diameter is smaller than the diameter of the mounting hole provided in the mounting portion of the plug and which is slightly longer than the total thickness of the mounting portion and the mounting chassis. By being attached to the chassis, the plug is provided with a floating function for the chassis or unit.

Further, a correcting means for moving the floating plug to a predetermined positional shift amount is provided in a region corresponding to the plug housing wall on a surface of the chassis to which the jack is attached, the surface facing the plug.

This means that when the jack-side unit is brought closer to the plug-side unit, first, the correcting means moves the floating plug to a predetermined displacement amount.

Accordingly, since the positional deviation can be absorbed by the guide provided by the taper provided on the housing wall of the plug, the jack-side unit is further brought closer to the plug-side unit, thereby realizing a reliable connection between the jack and the plug. be able to.
