Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating connector mounting structure on a motherboard in a communication base station device or the like.

[0002]

2. Description of the Related Art A conventional connector mounting structure of this type is shown in FIG.
As shown in, the size of the known floating connector is changed each time according to the number of tangents, and the floating connector 22 provided with the tangents 23, 24 for signals, power supplies, etc. However, the problem of fitting with the connector 26 on the unit side has been solved, but this method leads to an increase in the number of parts and an increase in cost. However, in consideration of increasing the number of types of parts and reducing the cost, as shown in FIG.
The number of tangential lines 30 and 31 to be connected can be increased by arranging a large number of floating connectors 27 on the motherboard 29 and a large number of floating connectors of the same type are arranged. Two
The movement 32 of 8 comes to slide freely.

[0003]

The first problem is that the floating direction of the floating connector on the motherboard cannot be controlled, and the connector on the unit side cannot be fitted by sliding in various directions. There were many. The reason is that while assembling subrack, etc., attention is paid to the tolerance of the unit mounting part, but the connector on the unit side is fixed, while the connector on the motherboard side is floating, so when mounting the unit. This is because the assembly tolerance and the like have been absorbed by the floating amount of the connector, but if there are many floating connectors, the fitting state with the connector on the unit side becomes complicated and the reliability of the fitting decreases.

The second problem is that the cost of the device has been increased by developing various types of connectors. The reason for this is that the communication base station device is a high-mix low-volume product, and unless the individual component levels are standardized, the device price cannot be reduced.

An object of the present invention is to mount a connector in which, when a plurality of floating connectors arranged on the rack side are fitted with a connector on the unit side at a time, the movements of the floating connectors are controlled and the connectors are fitted accurately. To provide the structure.

[0006]

A connector mounting structure according to the present invention is a structure for simultaneously fitting a plurality of floating connectors of the same type mounted on a mother board to a connector on a unit side, among the plurality of floating connectors of the same type. The fittings that are simultaneously fitted to one of the connectors are connected by one metal fitting so that the floating directions are matched.

In this connector mounting structure, the metal fitting has a square hole surrounding each of the plurality of floating connectors of the same kind with a gap smaller than a floating amount, and the floating connector is arranged on the motherboard with a floating amount smaller than the floating amount. It is fixed by fastening means so as to be able to move largely, and at least one slit hole is formed in the motherboard along the floating connector in the same direction as the floating direction, and the slit is provided at the end of the metal fitting. At least one convex projection shorter than the length of the hole and fitted in the slit hole may be provided.

According to this structure, a large number of floating connectors of the same type are provided on the connector (26 in FIG. 1) fixed to the unit side and the mother board (2 in FIG. 1) on the rack side (1 in FIG. 1). When fitting (3, 4 in FIG. 1), the floating connectors (3, 4) provided on the motherboard (2) are connected by one metal fitting (5 in FIG. 1), so that one connector The other connector slides in the same direction by floating in accordance with the movement, and the fitting is not performed separately for each connector but as if it were one large connector, and the fitting is performed accurately.

[0009]

Next, the present invention will be described with reference to the drawings.

1 to 3 are a perspective view, an exploded perspective view and a sectional view showing a first embodiment of the present invention. This first
In the embodiment, the two upper and lower floating connectors 3, 4 of the same type mounted and installed on the surface of the motherboard 2 are used.
And the metal fittings 5 that connect the two floating connectors 3 and 4 to the two square holes 6 and connect them as if they were one connector. The size of the square hole 6 is a size slightly larger than the outer dimensions of the floating connectors 3 and 4, that is, the size surrounding the periphery with a gap smaller than the floating amount of the floating connectors 3 and 4.

In such a configuration, two floating connectors 3 and 4 of the same type are vertically installed on the surface of the mother board 2 on the rack side 1. Next, there are square holes 6 into which the floating connectors 3 and 4 of the same type can be inserted and mounted, and vertically elongated slots 8 near the upper and lower ends 7 that can move more than the floating amount of the floating connector. Mounting is performed by using the metal fitting 5 in which the floating connectors 3 and 4 are inserted into the square hole 6 of the metal fitting 5. The metal fitting 5 is sandwiched between the boss 9 and the block 10 through the vertically long slot 8 and is fixed to the mother board 2 with the screw 11 so as to float in the vertical direction. 4 can be connected as if they were one connector, the sliding directions 12 can be matched, and a connector mounting structure can be obtained in which the floating connectors 3 and 4 can be fitted to the connector 26 on the unit side at a time. .

4 to 6 are a perspective view, an exploded perspective view and a sectional view showing a second embodiment of the present invention. This second
In the second embodiment, the positional relationship of the metal fittings 15 with respect to the two upper and lower floating connectors 3 and 4 and the size relationship of the square holes 16 are exactly the same as those in the first embodiment described above. The difference is that a large elongated hole 18 for floating provided on the metal fitting 15 and a plurality of end face protrusions 17 which are convex protrusions, and end face protrusions formed on the mother board 14 along the floating connectors 3 and 4 at a plurality of places. That is, the elongated hole-shaped slit hole 21 into which the 17 is inserted is provided. In addition,
The length of the slit hole 21 is long enough to allow the fitted end face convex portion 17 to move more than the floating amount of the connector. The same applies to the size of the long hole 18.

In such a structure, the boss 19 and the collar 20 are passed through the oblong hole 18 provided at one central portion of the metal fitting 15 to float the metal fitting 15, and the metal fitting 15 is moved left and right and in the rotational direction. Metal fitting 15 to suppress
The plurality of end face convex portions 17 formed on the left and right end portions of each of the screws are fitted into the plurality of slit holes 21 provided on the surface of the mother board 14 that are slightly wider than the plate thickness of the metal fitting 15 and are sufficiently long.
By fixing the metal fitting 15 to the mother board 14 via the boss 19 and the collar 20 at 1, the sliding directions 13 of the floating connectors 3 and 4 of the same type can be made to coincide with each other, and the connector 26 on the unit side can be made. A connector mounting structure that can be fitted at one time is obtained.

[0014]

The first effect is that by controlling the movements of a large number of floating connectors of the same type, a large number of rack-side connectors and unit-side connectors can be fitted at once. The reason is that by connecting multiple floating connectors of the same type with one metal fitting, even if there are many floating connectors of the same type, if one connector moves, other floating connectors also slide, and It is possible to match the movements of floating connectors of the same type, and it is possible to accurately fit the connectors on the unit side.

The second effect is that the movement of many floating connectors of the same type can be controlled at a low price without developing a new connector. The reason is a structure that uses a member that can be easily manufactured, such as a metal fitting, as a means for connecting a large number of floating connectors of the same type, and a structure that uses a cut product such as a boss and a block as a member that floats the metal fitting. This is because these are structures that can be easily manufactured by conventional techniques, so that they can be manufactured at a low price and the cost of adjustment work can be reduced.
