Description

[Detailed explanation of the invention] (Field of industrial application) This invention is a method for connecting card-like objects such as IC (integrated circuit) cards, ROM (read-only memory) cards, and printed circuit boards to connectors inside electronic and electrical equipment cases. This relates to a guide device when connecting by inserting the device toward the device.

(Prior Art) Conventionally, as shown in FIG. 3, this type of guide device includes a receiving connector 3 disposed on a chassis 1 in an equipment case via a printed circuit board 2, and a receiving connector 3 disposed in a vertical direction opposite to the receiving connector 3, as shown in FIG. A rectangular tube-shaped insertion guide 5 is inserted between the panel chassis 4 arranged at
Insert the panel from the socket 9 of the panel 8, and
There was one that was inserted and connected to the receiving connector 3 through the opening 10 of the chassis 4 and the inside of the guide 5. Furthermore, after inserting the unit case 6,
A lid panel 11 can be attached.

(Problem that the invention attempts to solve) However, the receiving connector 3 and the board connector part 7
In order to connect mechanically and electrically reliably and smoothly, the insertion guide 5 and its surrounding related parts must be firmly installed in the correct corresponding prescribed position. The problem was that it required a large number of parts, such as screw parts, and many assembly steps, making the product expensive.

This invention was made in order to solve the above-mentioned conventional problems, and its purpose is to provide a guide device that can simplify the structure and improve reliability.

(Means for solving the problem) Next, the configuration of this invention will be explained. A card-shaped object insertion guide device for electronic/electrical equipment is a cylindrical insertion guide device that connects an opening in a device panel and a connector installed on a printed circuit board inside the device, and has a card-like object inserted at the front end. , a horizontal positioning protrusion that fits into an engagement hole provided in the printed circuit board at the bottom of the rear end, and a presser piece for vertical positioning that contacts the top surface of the connector at the top of the rear end. Prepared.

(Function) With this structure, horizontal position regulation with the receiving connector is achieved by fitting the printed circuit board engagement hole with the protrusion at the bottom of the rear end, and at the same time, the vertical position Positioning is achieved by a hold-down piece for the connector.

Therefore, the accurate positional relationship between the connector and the guide device can be easily achieved and maintained just by fitting them together, and the simple direct connection mechanism reduces the number of parts and the assembly work process without the need for other peripheral parts. This reduces product costs and contributes to lower product costs.

(Example) An example of this invention will be described based on FIGS. 1 and 2.

An equipment front panel 21 is disposed perpendicularly to the front end of a chassis 20 that constitutes a part of the equipment case. On the chassis 20 is a printed circuit board 22.
are supported floating in parallel, and this printed circuit board 2
Two approximately U-shaped receiving connectors 23 are attached to the front end of the connector 2 in parallel. Correspondingly, the front panel 21 has a relatively large opening 24.
is formed.

The guide device 25 is entirely formed by integral molding of synthetic resin. The front end is a card-like object 26
The insertion port 27 is formed as a relatively large opening with a bell-mouth-shaped inclined surface. Note that when the card-like object 26 is a ROM card, a ROM 34 is built-in, and a connector section 35 is provided at the front end of the ROM 34.

A boss-shaped spacer 28 protruding rearward and downward from the lower center is provided at the rear end, and an upward protrusion 29 is provided at the tip thereof. Furthermore, rib-shaped pressing pieces 30 are provided that press down on the upper surface of the connector 23 extending rearward from both upper ends.

The spacer 28 connects the guide device 25 and the printed circuit board 22 with the connector 23 from the chassis 20.
It plays the role of being mounted and supported by floating it at a specified height position, and is attached to the chassis 20 with screws 31.

The protrusion 29 at the end of the spacer 28 is fitted into the engagement hole 32 of the printed circuit board 22, thereby positioning the spacer 28 in the left-right and front-rear directions.

By bringing the pressing piece 30 into contact with the upper side of the connector 23, the vertical position is regulated.

Since the positioning of the card-like object 26 and the receiving connector 23 in the horizontal and vertical directions is precisely defined in this way, adjustment work such as positioning is not required, and the insertion connection is achieved smoothly and reliably.

At this time, even if the card-like object 26 is strongly inserted, due to the engagement between the engagement hole 32 and the protrusion 29, the positional relationship between the two is maintained without shifting.

In addition, parts such as a sleeve that supports the printed circuit board 22 by floating it on the chassis 20 are also used as the spacer 28, and the connector 23 and the guide device 2
5. The front panel 21, etc. has a simple direct connection structure, which reduces the number of parts and assembly steps involved in tightening screws and attaching peripheral parts.

Elastic engagement claws 33 are formed on both side plates of the guide device 25 to fit into the openings 24 of the panel 21 . Since the insertion port 27 is larger than the card-like object 26, it is easy to pull out the card-like object 26 once inserted.

(Effects of the invention) As described above, according to this invention, the omnidirectional alignment of the insertion guide device and the receiving connector inside the device can be easily performed by directly combining the insertion guide device and the receiving connector inside the device, and card-like objects can be smoothly and reliably inserted. Various practical effects can be obtained, such as plug-in connection, reduction in the number of parts and assembly process, and reduction in product cost.
