Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical field of the invention The present invention relates to a no-insertion input (ZIF) connector used for electrical connection between circuit boards or between units such as a circuit board and a side panel in a communication device, etc. It is related to.

(2) Prior art and problems Figure 1 is a diagram for explaining a conventional normal connection connector. In the figure, 1.1a is a circuit board on which IC and other circuit elements are mounted, and 2 is a female connector. , 2a is a male connector that is fitted into the female connector. When connecting or disconnecting these connectors, insertion/extraction force is required, and the force required at this time generally increases as the number of pins increases. Moreover, the units on which circuit boards are mounted are becoming more and more densely packed, and as a result, the connectors that make electrical connections between the units have necessarily become multi-pole. In general, connectors with good electrical contact can withstand extremely large insertion/extraction forces. This makes insertion and removal difficult during testing and maintenance.
Carelessly applying excessive force may deform the connector pin or make it impossible to insert or remove it. In order to compensate for the above drawbacks, in recent years it has been introduced that no force is required when setting the connector, but if a secondary operation is performed after setting the connector! : To,! : Z connecting between SJ and knit
IF' (Zeo Insertion Force) connector appeared.

Figure 2 shows a conventional example.
．． 3a is a circuit board, 4 is a lead-out terminal on the circuit board 3, and 5 is a connection terminal of the circuit board 3a. Further, 6 is an elliptical cam, and 7 is its rotation axis. In the same figure, terminals 4 and 5
To connect them, the terminal 5 is pressed against the terminal 4 by rotating the cam 6 in the direction of the arrow, and the two are connected. However, when using the above connector, it is difficult to maintain a constant terminal contact pressure during contact.

(31 Purpose of the Invention The present invention has been made to solve the above-mentioned problems, and aims to provide a non-insertion/removal input connector that improves the contact reliability of a multi-pole connector, and has a simplified and compact mechanism. purpose.

(4) Structure of the invention and the above-mentioned object according to the present invention, in a connector for electrically connecting circuit units, an engaging tooth portion is formed on the terminal exposed side of a terminal holding member provided on one circuit board. death,
Separately from this, a slider having a retaining tooth portion that meshes with the engaging tooth portion is slidably provided, and the upper part of the slider is covered with a guide cover attached to the one circuit board, and the terminal holding member is covered with a guide cover attached to the one circuit board. The other circuit board having terminals supported in a cantilevered state is inserted into the board insertion groove bored in the end face, so that the terminals of the one circuit board and the terminals of the other circuit board are closely opposed to each other, and A bottle is removably inserted into the gap between the engagement portion of the retaining teeth and the slider to move the slider in the pitching direction of the terminal, and the movement of the slider causes the free end of the other terminal to be pushed out and deformed. This is achieved by providing an unplugged input connector characterized in that the terminals of the circuit board are brought into contact with each other.

The slider 14 has an upper portion covered by a guide cover 15 attached to the side panel 8. Next, a board insertion groove 16 is bored in the end face of the terminal holding member 12, and the circuit board 10 is inserted into the insertion groove 16. The terminals 11 of this circuit board 10 are supported in a cantilevered manner and have a free end 11a at one end. And the board insertion groove 1
When the circuit board 10 is inserted into the side panel 8
The terminal 9 of the circuit board 10 and the free end 11a of the terminal 11 of the circuit board 10 are in a positional relationship in which they are close to each other and face each other as shown in FIG.

FIG. 5 is an external perspective view of the bottle 18. The pin 18 is inserted into and removed from the gap between the engagement teeth 13 of the terminal holding member 12 and the engagement teeth 17 of the slider 14. FIG. 6 shows a state in which the terminal 9 on the side panel side and the terminal 11 on the circuit board 10 are connected, and the pin 18 is removed from the position shown in FIG. insert.

Then, the slider 14 moves to the right in the drawing, and the terminal pressing piece 1γa presses the free PA1 of the terminal 11 of the circuit board 10.
Transform 1a by 8. In the above, the slider 14 is the third
As shown in the figure, one to two or more are provided for each block. In the embodiment, one terminal 9.11 is provided for one slider 14.
The two columns correspond. Next, when removing the circuit board 10, perform the operation opposite to the above. That is, the bottle 18 is removed from the state shown in FIG. 6 and inserted into the engagement gap on the opposite side to the engagement teeth 13.

Then, the connection between both terminals is released and the state shown in FIG. 4 is reached. Then, the circuit board 10 is pulled out from the board insertion groove 16.

In addition, FIGS. 7 and 8 show the mounting of the circuit board and side panel (FIG. 7) and the terminal connection (FIG. 7) in other embodiments.

are maintained respectively.

An engaging portion 22a protrudes from the fixing member 22,
This is slidably fitted into the recess 24 of the slider 21. 21a is the free end 19 of the site channel side terminal 19;
This is a terminal suppressing piece of the slider 21 provided between a. To explain how to connect the terminals in the above configuration, first, connect the circuit board 10a to the terminal holding member 12a of the side panel 8a.
The terminal is inserted into the insertion groove 16a formed in the end face of the terminal, and the one terminal free end 19a and the other terminal free end 20a are positioned facing each other (see FIG. 7). Subsequently, the bottle 18a is removed from the state shown in FIG. 7, and inserted into the gap on the opposite side to the engaging portion 22a of the fixing member 22, as shown in FIG. Then, the slider 21 moves upward with respect to the drawing, and the terminal pressing piece 2
