Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of Industry-1] This invention relates to a component for mounting 4-J used for attaching a certain member to another member.

[Prior Art] In an electric device, there are cases in which it is desired to attach a device casing or the like so that a circuit board or the like can be moved to a certain extent in the surface direction of the device.

Conventionally, there are no single mounting parts that can be used in such cases, and mounting is performed by combining a plurality of parts.

[Problems to be Solved] As a result, there has been a problem that the installation space, installation man-hours, and parts costs increase.

[1 = 1 aspect of the invention] The purpose of this invention is to solve such problems,
The object of the present invention is to provide mounting parts suitable for the above-mentioned mounting applications.

[Means for Solving the Problems] In order to achieve this object, the mounting part according to the present invention includes a pair of end members engaged with each end of a coil made of an elastic material. The coils are held in a compressed state by being pulled by a pulling member so as to bring them closer to each other.

[Function] A coil that is pulled from both ends and held in a contracted state becomes almost a rigid body, and is almost impossible to expand or contract.
By applying a force in the lateral direction, a certain degree of bending deformation is caused by 1
■It has the property of returning to a straight state when the force is removed in a bent state.

Therefore, by using this mounting component, it is possible to mount, for example, a circuit board so that it can move to some extent only in its surface direction.

Further, the mounting parts having such a configuration can be easily miniaturized and the mounting space can be reduced.

[See the drawings below for examples! ((t, , An embodiment of this invention will be described.

FIG. 1 is a schematic sectional view showing an embodiment of the mounting part according to the present invention. The mounting part 10 shown in this figure is comprised of a pair of end members 12, 14, a plurality of coils 16 and a filament 18 made of an elastic material such as a spring sheath. As the filament 18, for example, a multi-core coated electric wire is used.

The end members 12 and 14 are of the same shape and have a flange 20 having, for example, a substantially hexagonal cross-sectional shape. A portion 24 is formed. The threaded portion 22 also has a 1,1 shape,
A hole connecting the internal space 26 and the internal space of the cylindrical part 24 is formed in the collar part 20.

Each end member 12,14 is inserted with its cylindrical portion 24 into each end of the coil 16 and pulled by the filament 18 until it is spaced apart such that the coil 16 is compressed by l. The filament 18 extends within the coil 16, each end of which extends in the interior space 26 of the threaded portion 22 of the end member 12.14.
It is fixed with adhesive etc.

The sufficiently compressed coil 16 becomes almost a rigid body and is almost impossible to expand or contract, but it can be bent to some extent by applying a lateral force, and when the force is removed in the bent state, it remains almost straight. It has the property of recovering. Since the end members 12, 14 are pulled by the filament 18, the mounting part 10 as a whole has such properties.

Therefore, by fixing the force end member 12 to, for example, a circuit board, and fixing the end member 14 of J to, for example, the device casing, the circuit board can be attached to the device casing so that it can move to some extent only in the plane direction. be able to. During this installation, threaded portions 22 are attached to the end members 12 and 14 to facilitate fixation of the end members 12 and 14 to the circuit board, device housing, etc.
is provided.

Note that the end of the filament 18 may be fixed to the end member 2.14 by a method other than the nose. Also, the end member 12.14
The shape of can also be modified as appropriate.

FIG. 2 is a schematic front view showing an example of how such a mounting component 10 is used. This use case concerns a test head for an IC testing system.

Here, I would like to discuss the technical issues regarding the test head.
Explain to m11-.

When inspecting ICs at the wafer stage, IC inspection 7-stem Tes I/Hera 1! is coupled to the blow μ.

For this connection, a contact board is provided on the test head side, and a spring pin contact ring is provided on the prober side. The contacts of this contact ring and the spring pin contacts of the ring are pressed together and electrically connected to each other.

Now, in connection with this connection, it is necessary to relatively align the contacts of the contact board and the spring pin contacts of the spring pin contact ring so that they come into proper contact.

For positioning, a guide post is embedded in the spring pin contact ring, and a guide post receiver is provided on the contact board side to receive the guide post.

However, in conventional test heads, the contact board is firmly fixed to the performance board (the performance board is fixed to the test head housing, and the spring pin contact ring is fixed to the blow μ housing). ), there was a problem that positioning the test head and the blow μ when they were connected was troublesome and very time consuming. Also, place i,? / If the misalignment is too large, a large force will be applied to the guide post and the guide post I/receiver, causing damage or severe wear to them, leading to problems such as poor alignment accuracy. Ta.

Such problems can be solved by using the mounting parts of the present invention for mounting the contact I board.

In FIG. 2, reference numeral 110 is a test head, which carries a performance port 112 and a contact board 114. 21 The contact board 114 has two guide post receivers 116 for receiving guide posts on the prober side.
It is fixed at point 1-.

The contact board 114 is the mounting component 10 of the present invention.
It is attached to the performance board 112 by the performance board 112 and
It is possible to move by a predetermined distance of 1 ft in each direction (4 rows). A ring portion 130 is fixed to the back surface of the contact board 114 with a screw hole, and the threaded portion 22 of the end portion fA' 12 of the mounting part 10 is screwed into the screw hole.

The threaded portion 22 of the external end member 14 is screwed into the internal threaded hole of the spacer 134, and the spacer 134 is attached to the performance port 112 by the screw 13E3.
1 is fixed.

A prober 140 includes a probe card 144, a spring pin contact ring 146, a marker 148, and the like. Spring pin contact ring 146
, each guide boss receiver 11 on the test head 110 side
Guide posts 149 are provided at two or more locations corresponding to 6.

Test head 110 is coupled to prober 140 from one side, resulting in the coupled state shown. At the time of this coupling, the guide post 149 and the guide post receiver 116 are fitted together, and the relative positions of the contact board 114 and the spring pin contact ring 146 are adjusted.

Here, the contact board 114 is movable to some extent in its surface direction. Therefore, test head 110
Even if the positioning of the contact board 114 and the prober 140 is not performed with such high precision, the positional deviation is absorbed by the movement of the contact board 114 in the surface direction.
149 and the guide boss receiver 110, resulting in damage or severe damage. Can prevent wear and tear. Then, the contact board 114 and the spring pin contact ring 146 are properly aligned, and one end of each spring pin contact 147 is properly contacted with a corresponding contact (not shown) on the surface of the contact board 114. It is reduced to 1.

Here, variations in the spacing between the contact I board 114 and the spring pin contact ring 146 are absorbed by the expansion and contraction of the spring pin contact I-147, but the -1 end of the spring pin contact 147 and the contact on the contact board 114 In order to maintain the contact pressure within a predetermined range, it is necessary to prevent the contact board 114 from escaping under 14 degrees of force. The component IO for take-out A/1 of this invention has almost no deformation in the length-force direction as described above.
), it is possible to satisfy such condition (1).

Note that in the coupled state with the prober 140, the contact I.
Although the weight of the board 114 etc. is applied to the mounting part 10,
Since the front mold is supported by the filament 18, the elongation of the coil 16 of the mounting part 10 is negligible.

[Effects of the Invention As is clear from the explanation in 1-1, according to this invention,
