By the way, for example, for the purpose of terminating a communication line, as shown in FIG.
Reference numeral 0 denotes a configuration in which a plurality of terminal blocks 106 in which a plurality of terminals 104 are fixed on the terminal base 102 are vertically stacked. In the case where connection is made to all terminals in a terminal plate in which a very large number of terminals are aligned in this manner, the conventional crocodile clip has to correspond one-to-one to each terminal, so that labor is large, and The operation space for the connection operation was extremely small, so the operation was complicated, and the operation efficiency was extremely low.

[0004] Further, since the connection strength relies only on the clamping pressure of the spring, the worker is hooked and disconnected after connection, or easily disconnected due to external factors such as vibration, resulting in electrical disconnection. , The reliability in connection work was low.

Accordingly, an object of the present invention is to provide a terminal plate connector capable of easily and quickly performing a connection operation, improving the operation efficiency, and improving the reliability of the connection operation. .

A connection terminal block movably provided along the direction facing the connection terminal and connecting the terminal and the connection terminal by moving to the terminal side, and applying a rotational biasing force to a symmetrical position of the connection terminal block; And a cam member for moving the connection terminal block itself.

[0007]

[0008]

According to this invention, after the connector main body is mounted on the terminal plate, the connection terminal block is moved to the terminal side of the terminal plate and positioned at a predetermined connection position. As a result, the terminals of the terminal plate and the connection terminals of the corresponding connection terminal blocks are connected collectively, and the electrical connection to all the terminals is performed simultaneously by a single connection operation.

Further, according to this invention, after the connector main body is mounted on the terminal plate, the cam member is operated, and the connection terminal block is positioned at the connection position by driving the cam member.

Similarly, the holding recess 76 is formed on the rear surface, and the holding recess 78 is formed on the front surface.

When the connection terminal block 6 is located at the connection position P ₁ in order to obtain a contact pressure, the connection terminal 7
Although “a” is set so as to exceed the lower surface of the terminal 104, it has an elastic function by the side pieces 70 b and 70 c so that the connection terminal 7 is not damaged by an excessive contact pressure and an appropriate contact pressure can be maintained. When the connection terminal block 6 is raised and each connection terminal 7 contacts each terminal 104, as shown in FIG.
It flexes in the side piece receiving portions 74c and 76c of the zero to absorb excessive contact pressure. At this time, the positioning piece 70c above the connection terminal 7 moves down the upper positioning recesses 74d, 76d of the block bodies 48, 50. Thereby, the connection terminal 7
Always contacts the terminal 104 with an appropriate pressing force, and a highly reliable electrical conduction state is maintained.

In practice, a wire such as a communication wire is wound around the terminal 104 to form a solder pile. As a result, flux or the like adheres to the contact surface of the terminal 104 with the connection terminal 7. The contact portion 70a of the terminal 7 has the ability to obtain a good contact state by breaking through a contact failure factor such as flux since the tip is sharp and the whole is inclined.

As a result, the shaft pin 84 is
It is prevented from rotating around 0 and is prevented from falling off.

The cam body 80 has a cam surface 80b having a distance difference t ₁ from the rotation axis in the rear direction with respect to the upward direction.
4d.

Next, the connection operation by the terminal board connector 2 will be described. Figure 2 is a connection terminal block 6 shows a state located at the retracted position P ₂ at the time of non-connection, the attachment to the terminal plate 100 are made in this state. When the mounting is performed, the front surface portion 108 of the terminal board 100 comes into contact with the stopper 24, and the terminal 104 is positioned such that each connection terminal 7 faces each terminal 104. In this state, the terminal 104 and the connection terminal 7 are in a non-contact state.

When the cam member 8 is rotated upward from the state shown in FIG. 2, the connection terminal block 6 is raised by the dimension t ₁ against the urging force of the spring 62, and as shown in FIG. obtaining a connecting position P _1. As a result, each terminal 104 and all the corresponding connection terminals 7 are collectively connected with an appropriate contact pressure.

Therefore, the work efficiency can be greatly improved as compared with the conventional one-to-one connection work. Also,
Since the terminal plate 100 and the connector main body 4 are completely positioned, and the connection terminal block 6 is firmly held by the connector main body 4 and the cam member 8, a reliable and stable connection strength is maintained. Reliability is improved. Incidentally, in the case of returning to the retracted position P ₂ to connect the terminal block 6 from the connection position P ₁ is rotated a cam member 8 downward. Thereby, the connection terminal block 6 is lowered under the urging force of the spring 62.

Next, the function of the erroneous mounting prevention member 64 will be described. As shown in FIG. 4, the lower part of the guide groove 22 has a through hole 22c into which the head 67 of the erroneous mounting prevention member 64 is fitted.
Are formed. Reference numerals 22 d and 22 e indicate through holes 22.
This is a non-functional element generated to easily form c. In a state where the connection terminal block 6 is positioned at the retracted position P _2,
As shown in FIG. 2, the head 67 is set so as not to protrude from the surface of the guide groove 22. When the connection terminal block 6 by the operation of the cam member 8 is positioned at the connection position P _1, as shown in FIGS. 10 and 11, the head 67 interferes with entry of the terminal plate 100 protrudes into the guide groove 22. Therefore, when the connecting terminal block 6 is in the connected position P ₁ is mounted in the connector body 4 against the terminal plate 100 becomes impossible, the terminals 10
4 and the connection terminal 7 are prevented from being damaged.

[0036] Note that after mounting the connector body 4 to the terminal board 100, the normal operation of moving the connecting terminal block 6 in the connecting position P _1, as shown in FIG. 9, the erroneous attachment preventing member 6
The moving pin 65 of No. 4 does not cause any trouble because the supporting pin 54c of the chuck member 54 and the spring member 66 are allowed to escape by the rising distance.

When the terminal board connector 2 is not used,
Since the upper surface of the connector body 4 is open, there is a risk that the connection terminal 7 may be damaged due to collision with other articles or the like. However, as shown in FIGS. By providing the protective cover 85, such a fear can be avoided.

The protective cover 85 includes, for example, a cover main body 86 that covers the upper surface of the connection terminal group 7 and the cover main body 8.
6, a front part 87, a rear part 88, and a horizontal part 89 extending horizontally on the left and right sides of the cover body 86.
89, and horizontal portions 89, 89, and side portions 90, 90 connected upward from the horizontal portions 89, 89.
At the corners surrounded by 9, 89, notch portions 92, 92 for engagement with the moving pins 65 of the erroneous mounting prevention member 64 are formed.

The protection cover 85 is fitted with the horizontal portions 89, 89 and the side portions 90, 90 engaged with the guide grooves 22. In the fitted state, the lower end surface 88a of the rear surface portion 88 is fitted to the rear plate. 14, and the horizontal portions 89, 89 are placed on the protruding edges 22b of the guide grooves 22,
In addition, the front portion 87 contacts the front end surface 10a of the side plate 10.
The side surface portions 90 and 90 has a width t ₂ the same height of the guide groove 22. Therefore, the protection cover 85 is prevented from moving upward and backward after fitting, not to mention downward.

Therefore, the protection cover 85 is connected to the connector body 4.
After fitting, the connection by setting the terminal block 6 in the connecting position P _1, before moving pins 65 of the erroneous attachment preventing member 64 is engaged with the engaging notch 92, 92 protrude, whereby been only allowed The movement in the direction is prevented, and the protective cover 85 is prevented.
Is held in the connector body 4 in a state where the detachment is prevented. Since the protective cover 85 is fixed to the connector body 4, it is possible to prevent the connection terminals 7 from being damaged due to contact or collision with other articles when not in use. In this example, the erroneous mounting prevention member 64 plays a role as a stopper member of the protective cover 85 in addition to the original erroneous mounting prevention function.

In the above-described example, each component has a specific shape. However, the present invention is not limited to this, and the design can be changed as appropriate as long as the above-described connection function can be achieved.

Further, in the above example, the application example in which all the connection terminals 7 are collectively connected to all the terminals 104 has been described. However, the present invention is not limited to this. The partial connection can be arbitrarily performed by restricting.

[0043]

According to the present invention, all the connection terminals corresponding to the respective terminals of the terminal board can be connected collectively by moving the connection terminal block and uniformly at all the connection terminals. In addition, the work efficiency can be greatly improved as compared with the conventional one-to-one connection work.

Further, since the terminal plate and the connector main body are positioned and the connection terminal block is also positioned and held on the connector main body, it is possible to eliminate disengagement due to external factors such as human error and vibration. In addition, the reliability of the connection can be improved by maintaining the connection strength reliably and stably.

Further, by providing the cam member, the connection movement of the connection terminal block can be surely performed with a small amount of labor, so that the operability can be improved.
