Abstract

(57) [Summary] [Purpose] Reverse insertion is prevented by creating a difference between the length of the upper stage in the insertion direction and the length of the lower stage in the insertion direction of a connector that has contact pieces on the upper and lower stages. [Structure] A female connector having contact pieces on the upper and lower stages has a structure in which the length in the insertion direction of the upper stage is shorter than the length in the insertion direction of the lower stage. The shape of the contact piece of the male connector is long on the top and short on the bottom.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a connector, and relates to preventing a connector from being inserted in the wrong direction.

0002

[Conventional technology]

Conventionally, connectors used for IC cards, etc. also use connectors that can be inserted in the opposite direction. has been done. In addition, there are cases where a staggered two-row arrangement is used to prevent reverse insertion. However, since the pins of the connector are thin, the end pins may bend with a little force when inserted upside down. The connector may get stuck. The structure of the IC card has been devised so that it can be inserted backwards. In some cases, preventive measures have been taken to prevent this, but due to insufficient space, the structure may be weak. If you insert it with relatively strong force, it will often go in, and if you insert it backwards, There was a problem with the IC card being damaged.

0003

[Problem that the idea aims to solve]

This invention was devised in view of the above conventional problems, and has contact pieces on the upper and lower stages. By creating a difference in the length of the upper row of the connector in the insertion direction and the length of the lower row of the connector in the insertion direction, Prevents reverse insertion.

0004

[Means to solve the problem]

In order to solve the above problems, the present invention uses a contact piece that has contact pieces on the upper and lower stages. In the connector, there is a difference in the length of the upper contact piece of the first connector and the length of the lower contact piece. A housing for the upper contact piece and a housing for the lower contact piece of the second connector are provided. The present invention provides a connector characterized in that the lengths of the connectors are different.

[0005]

[Effect]

According to the above configuration, the long contact piece on the upper stage of the first connector is connected to the long contact piece on the upper stage of the second connector. Insert the lower short contact piece of the first connector under the second connector. Insert into the long housing. If the first connector is reversed and inserted into the second connector, When inserted, only the long contact piece of the first connector and the long housing of the second connector will connect. However, the shorter contact piece and the shorter housing are not connected.

【Example】

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. Figure 1 shows the connector of this invention. 2 and 3 are external views showing other examples of the same connector. It is.

[0007] 1A and 2 are side views, and FIG. 1B is a top view. 1 is a male connector 2 is a long contact piece, and 2 is a short contact piece. 3 is the male connector housing fix the plurality of long contact pieces 1 and short contact pieces 2 and connect the male connector. is forming. 4 is the printed circuit board that makes up the device, and the male connector is attached to it. The signal from the connected device is exchanged with external equipment via the female connector. 6 is female 5 is a long contact piece of the type connector, and 5 is a short contact piece. 8 is a female connector A plurality of long contact pieces 6 and short contact pieces 5 are fixed in the housing, and a female connector is connected. It forms a kuta. 7 is the terminal of the contact piece, for example, where an IC card etc. is attached. It will be done. When the connectors are connected, the long contact piece 1 of the male connector is replaced by the female connector. The short contact piece 5 of the male connector is fitted with the short contact piece 5 of the connector, and the short contact piece 2 of the male connector is fitted with the female connector. It fits into the long contact piece 6 of the connector. If you turn the female connector upside down and connect it to the male connector, If inserted into the connector, both connectors will not mate. Figure 2 shows male connector The upper housing 3 is longer in the insertion direction, and the opposite female connector The housing 8 is short. If either connector is inserted upside down, If so, both connectors will not mate. Figure 3 is a top view showing the connection piece 2 of the connector installed. , the housings 9 of the two connection parts are longer in the insertion direction, and the opposite female type The housing 8 is short. Therefore, it is possible to prevent the device from being inserted backwards.

[0008]

[Effect of the idea]

As mentioned above, in this invention, the male connector and female connector are inserted into By making it have a stepped shape, you can prevent it from being inserted backwards, and the Since the contact piece of the connector is covered with a holder, it has an anti-static structure, and the contact piece It has great effects such as not getting dirty.
