Abstract

PURPOSE:To prevent the occurrence of the electrostatic destruction of ICs on a circuit board. CONSTITUTION:A connector cover 6 is detachable from a connector 3 possessing plural pins 4 including a pin connected to the ground electrode of a circuit board. The connector cover 6 is formed by a conductive member to be connected to all the pins 4 in an attached state to the connector 3. Therefore even if static electricity flows to the pins connected to signal input/output electrodes except the ground electrode of the circuit board among all the pins 4 of the connector 3, the static electricity flows into the ground electrode via the connection cover 6. Thereby it is possible to prevent the flow-in of the static electricity to ICs on the circuit board, even though the charged hand or the charged finger of a worker, or the charged component part of a machine touches the pin connected to the signal input/output electrode among all the pins 4 of the connector 3, during the mounting process of the circuit board into an electronic equipment 1.

And a connector having a large number of pins connected to the signal input / output electrodes is partially exposed to the outside.

[0003]

By the way, an electronic device of this kind is incorporated into an electronic device such as a word processor or a personal computer after shipment, and a worker's finger or a component of a machine charged at the time of installation is a connector. The pins may come into contact with each other, in which case static electricity may flow from the pins of the connector to the ICs on the printed circuit board, resulting in electrostatic breakdown of the ICs.

Therefore, there has been a demand for the appearance of an electrostatic breakdown preventive tool or the like capable of preventing the occurrence of electrostatic breakdown of an IC.

The present invention has been made in order to meet such a demand, and it is possible to prevent static electricity from flowing into an IC on a circuit board, thereby preventing electrostatic breakdown of the IC and a connector cover. An electronic device is provided.

[0006]

A connector cover according to the present invention is a cover member that is attachable to and detachable from a connector having a plurality of pins including pins for connecting to a ground electrode of a circuit board. , Is formed of a conductive member that is connected to all the pins when mounted on the connector.

An electronic device according to another invention of the present invention includes the connector cover of the present invention.

[0008]

In the present invention and another invention, even if static electricity flows to all the pins of the connector, which are connected to the signal input / output electrodes other than the ground electrode of the circuit board, this static electricity flows to the ground electrode through the cover member. It will flow.

Embodiments of the present invention will be described in detail below with reference to embodiments shown in the drawings.

FIG. 1 is a perspective view showing a connector cover and electronic equipment according to the present invention, and FIG. 2 is a perspective view showing the connector cover according to the present invention.

In FIG. 1, reference numeral 1 denotes an electronic device such as an FDD, and a housing 2 containing a printed circuit board (not shown) on which a large number of ICs (not shown) are mounted,
The connector 2 is attached to the rear end of the housing 2 and is partially exposed to the outside.

Of these, the connector 3 includes a large number of pins 4 connected to a ground electrode (not shown) and a signal input / output electrode (not shown) of the printed circuit board (not shown), and the pins 4 inside thereof. It is composed of a socket 5 having a receiving port 5a facing to the electronic device 1 and is attached to the electronic device 1.

Reference numeral 6 denotes the connector cover having a rectangular cross section, which is detachably attached to the connector 3 and is entirely formed of a conductive member formed by mixing carbon or the like into a foam material such as urethane or polyethylene. Has been done. The connector cover 6 is provided with two upper and lower rows of recessed grooves 6a extending in the left-right direction and opening to one side. The connector cover 6 is provided on the connector 3
Socket 5a of the socket 5 in a state of being attached to
Is closed and can be connected to the pin 4 which faces the concave groove 6a.

Reference numeral 7 denotes a handle for attaching and detaching the cover, which is attached to the end surface of the connector cover 6 on the end surface opposite to the concave groove 6a via a double-sided adhesive tape (not shown). Are formed of an insulating material such as vinyl chloride.

In the connector cover and the electronic device thus constructed, even if static electricity flows through the pin 4 of the connector 3 which is connected to the signal input / output electrode other than the ground electrode of the printed circuit board (not shown). This static electricity will flow into the ground electrode via the connector cover 6.

Therefore, in the present embodiment, even if a worker's finger or a component of the machine, which is charged when assembled into an electronic device, comes into contact with any of the pins 4 of the connector 3 which are connected to the signal input / output electrodes, It is possible to prevent static electricity from flowing into the IC on the printed circuit board (not shown).

Further, in this embodiment, the connector cover 6 closes the receiving port 5a of the socket 5 when it is mounted on the connector 3, so that the pin 4 in the socket 5 is closed.
It is possible to prevent the dust from entering and adhering to the inside of the socket 5.

Further, in this embodiment, since the connector cover 6 is a conductive member made of a foam material, the pin 4 can be inserted into and removed from the connector cover 6 even if the groove width of the concave groove 6a is small. Can be done easily.

Although the connector cover 6 is a conductive member made of a foam material in the present embodiment, the present invention is not limited to this, and FIG.
A conductive member 11 made of another plastic material as shown in (A) and a commercially available connector 12 as shown in FIG.
The same effect as that of the embodiment can be obtained even if it is attached and connected to all pins (not shown).

Further, in the present embodiment, an example in which the concave groove 6a is formed in the connector cover 6 has been shown, but in the present invention, the same number of concave portions as the number of the pins 4 may be provided in the connector cover. In this case, the pins 4 are fitted in the recesses of the connector cover so that they can be inserted and removed freely.

Further, in the present embodiment, an example in which the present invention is applied to FDD has been shown, but it goes without saying that the present invention can be applied to other electronic devices similarly to the embodiment.

In addition, the present invention is not limited to the above-described embodiments, and various effective modifications and changes can be made based on the technical idea of the present invention.

[0023]

As described above, according to the present invention and another invention, there is provided a cover member attachable to and detachable from a connector having a plurality of pins including pins connected to the ground electrode of the circuit board. Since the member is formed of a conductive member that is connected to all the pins when mounted on the connector, even if static electricity flows to the pins of the connector pins that are connected to the signal input / output electrodes other than the ground electrode of the printed circuit board, this Static electricity will flow into the ground electrode through the connector cover.

Therefore, even if a worker's finger or a component of a machine, which is charged when assembled into an electronic device, comes into contact with a pin connected to the signal input / output electrode among all pins of the connector, static electricity to the IC on the printed circuit board is generated. Since it is possible to prevent the inflow, it is possible to prevent the occurrence of electrostatic breakdown of the IC.
