Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector cover for a connector used for electrical connection in electronic equipment and the like, and more particularly to a connector cover for a connector used for a pachinko machine, slot machine (pachi-slot) or the like.

[0002]

BACKGROUND OF THE INVENTION Various connectors are used to make electrical connections in electronic equipment. As a connector of this type, for example, as shown in a perspective view in FIG. 2, a rectangular base 103 is provided with a connector main body 101 made of an insulating material in which a plurality of openings 102 are arranged vertically and horizontally.
Inside the connector 2, there are connectors 100 each internally supporting a female electrode 104. In this connector 100, as shown in the rear view of FIG. 3, electric wires 105 are connected to the respective female electrodes 104 on the back side of the opening 102, and the front side of the opening 102 is not shown in the figure. By coupling the male electrode to the connector internally supported, the male electrode and the female electrode are electrically connected by contact, and the electrical connection is made between the opposing connectors.

Such a connector is used in a wide range of electronic devices because the connector body and electrodes can be simply constructed. However, the opening is formed as a simple through hole and the female electrode is press-fitted therein. Due to this configuration, when the connectors are connected, a part of the female electrode and the electric wire connected to the female electrode are exposed through the opening on the back side of the connector body. Therefore, this type of connector
When it is used as a part of an electronic circuit of a game machine base such as a punch or pachi-slot, a part of the electronic circuit of these machine bases is exposed at the connector.

In recent years, in pachinko and pachislot machines, it has become a problem to perform various illegal operations on the machine base in order to illegally increase the number of balls and medals to be paid out. Unauthorized operation is added to the electric circuit inside the table to increase the number of balls and medals. In that case, for the connector that is electrically connected to the machine base, contact the exposed part of the connector with a metal wire to short-circuit the circuit, or send an unauthorized electrical signal from the outside through the exposed part of the connector. A computer mounted on a machine is caused to malfunction by sending it to the machine.

For such a problem, it is preferable to use a connector having a structure in which the electric wire and the electrode are not exposed, for example, a connector in which the connecting portion between the electrode and the electric wire is molded with a resin. It is difficult to connect the wires to manufacture the connector, and it is an obstacle to the automation of the assembly work when assembling the machine base, which in turn causes an obstacle to lowering the price of the machine base. Become. Further, when various connectors having the same outer shape and outer dimensions but different electrode arrangements and electric wire connection forms are required, it is extremely complicated to design and manufacture connectors corresponding to these connectors. As
It also becomes a factor of high price. Further, there is a problem that maintenance work of the electronic circuit after it is mounted on the machine base becomes troublesome.

An object of the present invention is to apply an existing connector with a simple structure to prevent the electrodes and electric wires from being exposed in the connector, and prevent unauthorized operation when applied to a machine base such as a pachinko machine. The present invention provides a connector cover that makes it possible.

[0007]

A connector cover of the present invention is a connector cover for covering a connector to which an electric wire is connected to an electrode incorporated in a connector body, and is fitted to each other so as to sandwich the connector. It is characterized by comprising a pair of connector covers having the same shape, and covering at least the electrode and the connection region between the electric wire and the electrode while sandwiching the connector. For example, the connector cover has a wall portion protruding toward the opposing connector cover, a gap portion into which the wall portion of the opposing connector cover can be fitted, and a concave groove into which a ridge provided on the connector can be fitted. And a clamp wall that cooperates with the opposing connector cover when attached to the connector and holds the electric wire connected to the connector.

According to the present invention, by fitting the pair of connector covers to each other and sandwiching the connector therebetween,
The electrode inside the connector and the connection with the electric wire connected to the electrode are covered with a connector cover.
It becomes possible to prevent electrical connection from the outside. Therefore, when the connector cover of the present invention is applied to a connector provided on a machine base such as a pachinko machine, it is possible to prevent an illegal operation on the machine body of the pachinko machine.

The locking lever 107 is capable of moving the hook 107a upward by manually pushing down the base end portion 107b to disengage the hook 107a from the locking groove of the opposing connector and detach the connector from the opposing connector. is there. The locking lever 107 may be provided on both upper and lower surfaces of the base 103. Edges on the back side of the upper surface and the lower surface of the base 103 are formed as protruding ridges 108 protruding upward and downward in both end regions except the central region where the locking lever 107 is present.

On the other hand, the connector cover 200 is composed of a pair of connector covers which are resin-molded in exactly the same shape. Here, both connector covers 200 are formed of transparent resin. 4A to 4D are a plan view, a left side view, a right side view, and a sectional view taken along the line AA of the connector cover 200, respectively. A bottom plate 201 having a width dimension substantially equal to that of the connector body 101 of the connector 100 and having a tapered width dimension from a front end portion toward a rear end portion;
The bottom plate 201 extends along both side edges of the bottom plate 201.
01 and the left side wall 202 and the right side wall 2 which are erected vertically.
03 and. The horizontal direction here is the bottom plate 2.
Reference is made to the state in which the inner surface of 01 is directed upward and viewed from the front. The right side wall 203 is formed to be higher than the left side wall 202, and an upper edge portion 204 in almost half of the height direction is formed to have a thin plate thickness. A wedge-shaped engaging projection 205 is integrally formed at least at one position on the outer surface of the upper edge portion 204, here at two positions on the front side and the rear side of the bottom plate 201. Further, a guide wall 206 extending in parallel with the inner surface of the left side wall 202 is set up on the inner surface of the bottom plate 201 along the left side wall 202, and the left side wall 202 and the guide wall 206 are provided. The upper edge portion 204 of the right side wall 203 can be inserted into the gap portion 207 constituted by. Further, an engagement window 208 penetrating in the thickness direction is opened at a position of the left side wall 202 corresponding to the engagement protrusion 205 of the right side wall 203, and the engagement protrusion 205 is formed in the engagement window 208. Are engageable with each other.

Further, an inward projection 209 formed by projecting the bottom plate 201 in the plate thickness direction from the outer surface side toward the inner surface side is formed in the central region in the width direction of the front edge portion of the bottom plate 201. There is. The locking lever 1 of the connector 100 is attached to the outer surface of the bottom plate 201 by the inward projection 209.
The recess 210 is formed at a position corresponding to 07. A concave groove 211 extending in the width direction is formed on the inner surface of the front edge of the bottom plate 201.
Corresponds to the ridge 108 of the connector 100, and the ridge 108 can be fitted therein. Further, the bottom plate 20
A clamp wall 212 is formed so as to project inward in the width direction on the inner surface of the trailing edge portion whose width dimension is reduced. Here, the height of the clamp wall 212 is formed to be approximately equal to the height of the inward projection 209.

According to the above structure, the connector cover 200 is attached to the connector 100 to which the electric wire 105 is connected.
When mounting the connector 10, as shown in FIG. 1, the inner surface of each bottom plate 201 of the pair of connector covers 200 is fixed to the connector 10
The connector 100 is fitted so as to sandwich it from the upper side and the lower side of the connector 100 toward 0. FIG. 5 is a perspective view of the fitted state, and FIG. 6 is a perspective view of the back side thereof. 7A and 7B are cross-sectional views taken along the line BB and CC in FIG. Both connector covers 20
When 0 is fitted from above and below, the upper edge portion 20 of the right side wall 203 is
4 is inserted in the gap 207 between the inner surface of the left side wall 202 and the guide wall 206. Then, when it is inserted to a predetermined position, the engagement projection 205 engages with the engagement window 207, whereby the right side wall 203 and the left side wall 202 are integrally coupled, and both connector covers 200 are integrally coupled. It Then, by coupling the both connector covers 200 as described above,
The peripheral side of the connector 100 is surrounded by both connector covers 200.

At the same time when such coupling is performed, the protrusions 108 on the upper surface and the lower surface of the connector 100 are engaged in the concave grooves 211 formed in the front edge portions of the connector cover 200, Due to the engagement between the groove 211 and the protrusion 108, the connector 100 is supported in the front and rear direction in a fixed state in both connector covers 200.
Therefore, in this state, the operator can
By gripping 0, the connector 100 can be fitted into or removed from the opposite connector. Further, the inward protrusions 209 provided on the bottom plate 201 of the connector cover 200 are advanced inward in the vertical direction with respect to the upper surface and the lower surface of the base 103 of the connector 100, so that both connector covers 200 face inward. The electric wire 105 is clamped from above and below by the protrusion 209. Along with this, the clamp wall 212 provided at the rear edge portion of the bottom plate 201 similarly holds the electric wire 105 from above and below. These inward projections 209 and clamp walls 212
Even when tension is applied to the electric wire 105 by an external force due to the electric wire 105 being clamped by the electric wire 105, the tension is applied to the electric wire 105.
There is no possibility that the connection will be damaged by reaching the connection portion between the female electrode 104 and the connector 100 in the connector 100. Further, a recess 210 is formed on the outer surface of the bottom plate 201 on which the inward projection 209 is formed. Since this recess 210 is a position corresponding to the locking lever 107 of the connector 100,
When the base end portion 107b of the locking lever 107 is pressed downward, it does not interfere with the outer surface of the bottom plate 201 of the connector cover and interferes with the operation, and facilitates the operation of releasing the locking with the opposite connector. It will be possible.

By thus covering the connector 100 with the connector cover 200 in an enclosed state, the connector 10
The female electrode 104 of 0 and the connecting portion of the female electrode 104 and the electric wire 105 are completely covered by the connector cover 200. Therefore, when the connector 100 is used for a pachinko machine, a pachi-slot machine, etc.
Even if you try to make an electrical connection to 00,
The realization becomes extremely difficult. Even if the connector cover 200 is to be removed, both connector covers 200
A plurality of engaging projections 205 and engaging windows 208 that connect the two are arranged on both side surfaces.
It is necessary to deform the engaging projection 205 inward when removing from the engaging window 208. However, since the upper end portion 204 of the right side wall 203 where the engagement protrusion 205 is formed is inserted into the gap portion 207 between the left side wall 202 and the guide wall 206, it is impossible to deform the upper end portion 204 inward. This cannot be done, and it becomes almost impossible to remove the engagement protrusion 205 from the engagement window 208. Therefore, the connector cover 200 has to be destroyed, but since such a destruction work is conspicuous, it is effective for the Goto hesitant to hesitate to execute an illegal operation.

The connector 100 is attached to the connector cover 2
Even when trying to pull it out from between 00, the protrusion 108 and the groove 21
It becomes almost impossible to pull out by engaging with 1. Further, even when a metal wire is inserted through the opening of the rear edge portion of the connector cover 200 through the electric wire 105 and an electric connection is attempted with respect to the female electrode 104 or the like, the electric wire 105 is fixed by the clamp wall 212 at the rear edge portion. Since the electric wires 105 are held in close contact with each other, and the electric wire 105 is also held in close contact with the inward projections 209 further ahead, the metal wire is inserted between the electric wires to the connection portion. Making electrical connections is nearly impossible.

Further, in this embodiment, the connector cover 2
Since 00 is made of transparent resin, the connector 100
It is possible to see through the connector portion of the female electrode 104 or the electric wire 105 through the outside of the connector cover 200, and if abnormal electrical connection is made to the connector 100 or abnormal parts are present. This can be easily found even when connected. As the resin for the connector cover, ABS, ABS alloy, polycarbonate and polycarbonate alloy are preferable if they are not easily broken and transparency is desired.

Here, the present invention is not limited to the connector having the structure described in the above-mentioned embodiment, and the connection part between the electrode incorporated in the connector and the electric wire connected to the electrode is exposed. It goes without saying that the connector cover of the present invention can be applied in the same manner as in the above-mentioned embodiment as long as the connector has such a structure.

[0019]

As described above, according to the present invention, by fitting a pair of connector covers to each other and sandwiching the connector between them, an electrode built in the connector and an electric wire connected to the electrode. It is possible to prevent the electrical connection from the outside by covering the connection portion with and with the connector cover. Therefore, when the connector cover of the present invention is applied to a connector provided on a machine base such as a pachinko machine, it is possible to prevent an illegal operation on the machine body of the pachinko machine. Further, since the connector covers of the present invention form a pair using two of the same structure,
Only one mold is required to manufacture the connector cover,
Further, the connector cover itself may be of one type, which is easy to manufacture and easy to manage, and even if one of the pair of connector covers is defective, only one of them can be replaced to replace it. The function can be secured.
