Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] The present invention provides a connector float structure in which a guide pin portion and an attachment portion are integrated into a single structure, which is compact and highly accurate.

[Industrial application field]

The present invention relates to a connector float structure, and more particularly to a connector float structure that allows a connector housing mounted on a package and a connector housing mounted on a mounting member to be easily fitted to each other.

[Conventional technology]

A connector having a structure in which a package in which a conventional electronic component is mounted, a unit accommodating the package, and a rack on which the unit is mounted is connected, and a connector mounted on the package and a connector mounted on the rack are connected by a plug-in (slide-in), In particular, there is known a connector float structure in which a plurality of connectors are mounted in one package and plug-in connection is performed, and a connector float structure in which deviations due to respective mounting errors or the like are fitted to each other by floating the connectors.

FIG. 2 shows a schematic view of a conventional connector float structure.

In FIG. 2, a connector float device 1 having a float screw 1a has a guide pin 3 for a connector housing 2.
The mounting frames 4 located outside the mounting position are separately provided.

Therefore, in the integrated connector structure, the connector float structure 1 requires an extra length L, 2L in the case of FIG.

Furthermore, there is a problem that flexibility is lacking because the float amount is uniquely determined by the inner diameter of the float screw insertion hole provided in the housing and the outer diameter dimension of the float screw.

[Means for solving problems]

According to the present invention, the above-mentioned problem is that the guide pin is mounted on the connector housing in parallel with the connector attachment / detachment direction, and the guide hole is provided on the coaxial line of the guide pin and on the opposite side to the guide pin mounting side. A connector float structure is characterized in that the connector housing is floated with a float screw through an attachment member to which the connector housing is attached.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 (a) and 1 (b) are schematic views for explaining one embodiment of the present invention. In particular, (a) is a female side of a connector structure,
(B) is the male side.

In FIGS. 1A and 1B, the connector housing 2a
Is mounted in the package 6 and has a guide hole 5
Have. On the other hand, the connector housing 2b is firmly attached to the attachment frame (frame mechanism) 4 and has the guide pin 3. Connector housing 2b on the side opposite to the mounting position of the guide pin 3
The float screw 1a is provided through the mounting frame 4.
The mounting frame 4 to which the float screw 1a is attached has a hole 4a having a predetermined float amount (a gap with the float screw).

For example, the guide pin 3 included in the connector housing made of a resin molded product has a chamfered portion 3a for securing a required guide amount and a female screw portion to which a float screw is screwed, whereby the guide pin portion and the mounting portion are formed. Since it is directly above, the size of the connector housing can be reduced and the accuracy can be improved.

Also, regarding the relationship between the external dimensions of the float screw that holds the required float amount and the hole dimensions of the mounting frame, the float amount can be freely selected (within the guideable range) simply by changing the hole dimension of the mounting frame. be able to.

〔The invention's effect〕

As is apparent from the above description, according to the connector float structure of the present invention, by integrating the guide pin portion and the mounting portion, it is possible to achieve downsizing and high accuracy, and to control the float amount with the mounting frame. It becomes possible.
