DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an exploded perspective view illustrating the relationship between an interposition support frame member according to the present invention, a PC card whose connection portion is reinforced by the interposition support frame member, and a connector. is there.

According to FIG. 1, an interposition support frame member 11 made of an insulating material has a bottom plate portion 13 having an appropriate vertical width and a horizontal width and having a substantially rectangular shape, and standing on both sides of the bottom plate portion 13. The side plates 14, 14 provided, and the top plate 15 covered between the side plates 14, 14 support a relatively flat connector 32 provided in a cable 31 drawn from an external peripheral device. Opening 16 and other opening 1 that can be inserted through
6, and at least support arms 19, 19 protruding from both side plates 14, 14 near the other opening 17 in the frame body 12. .

The frame main body 12 has two ribs 18 on the inner surfaces of the bottom plate 13 and the top plate 15 along the insertion direction of the connector 32, respectively. Connector 3 while allowing its insertion through
2 can be supported from both upper and lower directions. Note that the ribs 18 may be raised at appropriate positions allowing the insertion of the connector 32, and the number of the ribs 18 may be three or more. Also, without providing the rib 18, the bottom plate 13
The connector 32 may be supported so as to be in sliding contact with both inner surfaces of the top plate 15 and the top plate 15.

Each of the support arms 19 has a card inlet 3 with a lid 37 provided in a casing 35 of the measuring instrument.
6, a support portion 20 in contact with the rear end portion 33a in the insertion direction of the PC card 33 fed through the other side opening 17 side, and a card introduction port 36 of a casing 35 below the support portion 20. And a tubular portion 25 having a through hole 22 through which a screw member 23 screwed into a female screw portion 38 provided below and projecting toward the casing 35 is provided. It is desirable that the through hole 22 be provided with a female screw portion screwed with the screw member 23 at an intermediate position so that the screw member 23 can be temporarily fixed.

Further, a support portion 20 provided on the support arm portion 19
Is the other side opening 1 as shown in FIGS.
7 is formed by a groove 21 into which a rear end portion 33a of the PC card 33 is inserted so as to be freely held. Note that the support portion 20 may have a flat vertical surface instead of the groove portion 21, and the vertical surface may be in contact with the rear end portion 33 a of the PC card 33.

Next, the structure for reinforcing the connecting portion between the PC card and the connector according to the present invention, which is realized by using the interposition support frame member 11 having the above configuration, will be described together with the operation of the interposition support frame member 11. .

When sending the PC card 33 from the card introduction port 36 provided in the casing 35 constituting the measuring device and mounting it on the measuring device side, first, the PC card 33 is inserted into the opening 16 on one side of the interposition support frame member 11. The connector 32 of the cable 31 drawn from the external peripheral device is inserted from the side to the other side opening 17 side.

After the connector 32 is projected from the opening 17 on the other side of the interposition support frame member 11, the socket 32 a is connected to the insertion pin 34 of the PC card 33, so that the connector 32 and the PC card 33 are connected. The connecting portion 28 is formed between the two as shown in FIG.

Thus, while the PC card 33 is being fed from the card inlet 36 of the casing 35 in the state shown in FIG.
5 is brought into contact with a female screw portion 38 located below the card introduction port 36 so as to face each other, and the screw member 23 is fed through the through hole 22 of the cylindrical portion 25 under such an arrangement relationship.
The mounting support frame member 11 is screwed onto the female screw portion 38 and the casing 3
Fix to the side of 5.

At this time, under the state where the support portion 20 formed on the support arm portion 19 and the rear end portion 33a of the PC card 33 are in contact with each other, the frame main body portion 1
A predetermined interval determined by the length of the cylindrical portion 25 is formed between the casing 2 and the casing 35. That is, the interposition support frame material 11
When the PC card 33 is fixed to the casing 35 side, the measurement is performed with the rear end portion 33a of the PC card 33 slightly projecting from the card introduction port 36 and supported by the support portion 20 of the support arm portion 19. The connector 3
The second side is also stably supported in the vertical direction by the ribs 18 of the interposition support frame member 11. Also, if the support portion 20 is P
When the PC card 3 is formed by the groove 21 into which the rear end 33a of the C card 33 can be introduced, the PC card 3 is inserted into the groove 21.
3 can be more stably mounted on the measuring instrument side while holding the rear end 33a.

Further, in this case, the connector 32 is supported so as to be wrapped in the interposition support frame member 11 integrally fixed to the casing 35 side, while the PC card 33 is mostly supported by the casing 35. As a result, the connection portion 28 formed between the connector 32 and the PC card 33 can also maintain a stable connection state.

That is, the strength of the connection portion 28 formed between the connector 32 and the PC card 33 is reinforced by the interposition support frame member 11 fixed to the casing 35, and damage due to external force is effectively prevented. Will be able to do that.

Furthermore, as a result of the PC card 33 after being mounted being unable to move by contacting the support portion 20 of the support arm portion 19 of the interposition support frame member 11, it cannot be erroneously extracted from the casing 35 side. become.

After completing the measuring operation according to the predetermined procedure, the PC card 33 can be pulled out from the card introduction port 36 while removing the screw member 23 from the casing 35 side and removing the interposition support frame member 11. . Further, the PC card 33 connected to the connector 32 can be easily separated by pulling while pressing the operation piece 32b of the connector 32.

[0023]

As described above, according to the first aspect of the present invention, the connector can be stably supported in the frame main body, and the interposition support frame can be provided via the support arm. Since the member can be integrally fixed to the side of the casing, it can be effectively used as a reinforcing member for a connection portion formed between the connector and the PC card.

According to the second aspect of the present invention, the connection between the connector and the PC card mounted on the measuring instrument side through the card introduction port can be reliably and stably made through the interposition support frame material. In addition to being able to reinforce the strength of the PC card while supporting it, it is also possible to reliably prevent the PC card from being accidentally pulled out after being installed, so that the measurement work using the measuring device and external peripheral devices can be performed smoothly and It can be performed stably.

Further, in any of the above inventions, when the support portion of the support arm portion is formed by a groove portion which communicates with the opening on the other side to allow the PC card to be freely held, the rear portion of the PC card can be provided. The end portion can be held by the interposition support frame member, and the strength of the connection portion can be more effectively increased. In addition, when ribs that can support the connector from the upper and lower surfaces are ridged on the inner surface of the frame main body, even if the connector has a certain thickness, the insertion supporting frame material is allowed. Can be supported under a more stable state.
