Abstract

PROBLEM TO BE SOLVED: To improve the electrical connection reliability of male and female terminals. SOLUTION: Rear guide projections 13, 14 formed at an external connector body 11, and rear guide grooves 6, 7 formed at an internal connector body 4, are arranged outside, while an engaging projection 17 formed at the external connector body 11, and an engaging hole 8 formed in the internal connector body 4, are arranged inside. Consequently, even if a worker inserts the external connector 3 in the internal connector 1 in the position shifted state of the rear guide projections and rear guide grooves, the insertion of the external connector 3 is impeded by the contact of the rear guide projections 13, 14 with the internal connector body 4, so that the male terminal 5 is never bent by the external connector body 11.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game component connection device for electrically connecting switches and circuit boards, which are game components used in game machines such as pachinko machines and slot machines.

[0002]

2. Description of the Related Art FIG. 6 shows a conventional game component connection device.
In FIG. 6, in a state where the circuit board 102 on which the internal connector 101 is mounted is mounted inside the case 103, an external connector 105 connecting the wiring 104 is formed in the opening 10 formed in the case 103 from the outside of the case 103.
6 and fitted into the internal connector 101. In this case, the body 10 made of an insulating material of the external connector 105 is used.
7 are inserted into guide grooves 111; 112 formed in the body 110 made of insulating material of the internal connector 101, so that the terminals 113 of the external connector 105 and the terminals 11 of the internal connector 101 are inserted.
4 coaxially oppose each other. Continue with the external connector 10
5 is pushed into the internal connector 101 so that the terminal 113 of the external connector 105 and the terminal 114 of the internal connector 101 are fitted and connected to each other, and then the engagement protrusion 11 formed on the body 107 of the external connector 105 is formed.
5; 116 engages with engagement holes 117; 118 formed in the body of the internal connector 101. Thereby, the internal connector 101 and the external connector 105 are connected to each other.

[0003]

However, in the conventional example, since the internal connector 101 is arranged to be recessed inside the case 103, the operator cannot connect the external connector 1 to the external connector.
It is difficult to fit the internal connector 101 into the internal connector 101 by holding the body 107 of the external connector 105 by hand, so the worker holds the wiring 104 of the external connector 105 and fits the external connector 105 into the internal connector 101. For this reason, when the body 107 of the external connector 105 and the body 110 of the internal connector 101 meet,
04, the guide projections 108; 109 and the guide grooves 111; 1
In some cases, the external connector 105 is pushed into the internal connector 101 without securing a position where the external connector 105 properly fits. In such a case, the conventional example is a guide projection 10
8; 109 and the guide grooves 111; 112 are inside, the engaging projections 115; 116 and the engaging holes 117; 118 are arranged outside, and the engaging projections 115; Of the external connector 105 with the body 107 of the external connector 105 being obliquely opposed to the body 110 of the internal connector 101 because the body 107 of the external connector 105 is obliquely opposed to the body 110 of the internal connector 101. 119 is taken into the body 110 of the internal connector 101, and the operator pushes the external connector 105 while holding the wiring 104 so as to fit the internal connector 101. The inconvenience of being pushed and bent by the body 107 of the external connector 105 occurs. . When the terminal 114 is bent, the fitting operation of the internal and external connectors 101 and 105 is stopped, and then the internal connector 101 whose terminal 114 is bent is replaced with a new internal connector 101, or the terminal 114 is bent. For example, the circuit board 102 having the internal connector 101 is replaced with a new circuit board 102. The reason is that even if the bent terminal 114 is corrected, it is impossible to completely correct the terminal 114 as if it were a legitimately made terminal. This is because it is undeniable.

Accordingly, the present invention provides a game component connecting apparatus capable of improving the electrical connection reliability of the male and female terminals by linearly fitting the inner and outer connectors without tilting each other.

[0005]

According to the present invention, the guide projections and the engagement projections with respect to the connector body are arranged on the outside, and the guide grooves and the engagement grooves with respect to the connector body are arranged on the inside. When one connector body and the other connector body are fitted with each other while the positions of the guide protrusion and the guide groove are shifted while the protrusion and the guide groove meet, the guide protrusion contacts the other connector body. Accordingly, one or the other connector body does not interfere with the terminal on the other side and does not bend the terminal on the other side, and the terminal on the other side keeps a properly formed shape. When one connector body and the other connector body are fitted to each other after the guide protrusion and the guide groove meet, the guide protrusion and the guide groove are fitted to each other so that both terminals are connected to each other. On the other hand, the connection between the two terminals is fixed by the engagement between the engagement protrusion and the engagement hole.
