Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector terminal used in a connector for electrically connecting printed circuit boards, and a connector housing the connector terminal.

Conventionally, the methods for connecting printed circuit boards in electronic equipment, etc. are generally: ■Electric wire only (some terminals are used);■
There are three types of connectors: one that uses crimp or press-fit terminals, and one that uses board-to-board connectors (board-to-board connectors), but the two methods above can be installed freely without being affected by the mounting position on the printed circuit board. While it is possible,
It had the disadvantage of high cost.

In other words, in the case of (■) above, the wires are inserted into the printed circuit board one by one, which requires a considerable amount of effort and time.
This is because the number of parts increases in case (2).

In addition, in the case of (■) above, when installing the connector, it is necessary to move one of the printed circuit boards, which not only limits the mounting design of the device, but also makes it difficult to absorb misalignment of the printed circuit board. In some cases, it may become impossible to install or a strong force may be applied to the contacts, causing poor contact.

In view of the above, the present invention can be mounted on a printed circuit board without moving it, and therefore not only does it not limit the mounting design of the device, but also prevents the printed circuit board from being misaligned. This was done in order to provide a low-cost product that can absorb and prevent installation failure and poor contact.

Hereinafter, the present invention will be explained in detail based on the illustrated embodiment. In the figure, 1 is a connector terminal, which is integrally bent and formed by a board insertion part 2, a pin support part 3, and a movable plate 4 that connects the two. . The board insertion part 2 is inserted into an insertion hole Pa drilled in the printed circuit board P and electrically connected to the board through soldering or the like.
Although it is formed by the pair of elastic pieces 2a, 2a toward the rear, it is of course possible to use other known pieces.
It can also be formed downward as shown by the two-dot chain line in FIG.

The pin support part 3 is for supporting and electrically connecting the pin A, and has a U-shaped cross section with a downwardly closed opening, a pin insertion hole 3a is bored in the upper surface, and the central part of the peripheral wall is inward. The pin contact pieces 3b, 3b are bent in the opposite direction to hold the piso A, and are electrically connected to the pin contact pieces 3b.

In addition, the pin insertion hole 3a is elongated in the front-rear direction to allow for the insertion of the pin A in this direction.
In this way, the positional deviation of the pin A in the front-rear direction is dealt with.

The movable plate 4 has its front and rear ends connected integrally with the board insertion part 2 and the piso support part 3, respectively, to connect both 2 and 3, and is twisted at a right angle to connect the vertical plate part a and the horizontal plate part 4b. The vertical slope portion 4a can be bent in the thickness direction, that is, in the horizontal direction, and the horizontal plate portion 4b can be bent in the vertical direction.

In this way, it can be bent vertically and horizontally, and
As described above, the pin insertion hole 3a is provided with a margin in the front and rear directions, so that it can be moved in three directions, and communication between the fixed printed circuit boards and misalignment can be dealt with when the problem occurs.

Note that this movable plate 4 may be bent at right angles to form a vertical plate portion 4a' and a horizontal slope portion 4b' as shown in FIG.

5 is a housing, and the pin support part 3 of the connector figure above is
It is for storing a plurality of pins and arranging them in parallel at regular intervals, and the upper surface thereof is provided with openings 5a, 5a, . . . corresponding to the pin insertion holes 3a.

Reference numeral 6 denotes connector terminals 1, 1, . . . housed in the housing 5.
This is a separator that connects the starting ends of the board insertion parts 2, 2, etc., and is used to keep the distance between the board insertion parts 2, 2, and so on constant.By attaching this separator, the board insertion parts 2,
2. The work of inserting the substrates P into the insertion holes Pa, Pa, etc. can be performed all at once and easily.

In addition, this separator 6 and the housing 5 are formed into an integral structure via connecting portions 7, 7 to form a "connector terminal L".
After storing the tortoise..., by removing this connecting part 7, it is possible to simplify the work of storing the tortoise and reduce the number of parts.

Next, an example of the use of the connector of the present invention will be explained based on the rhombus diagram and the groove diagram. First, is there a connector terminal in the housing 5? Store the pin support part 3 of the crab field.

Then, as shown in Fig. 4, a printed circuit board P with a step
, P', the insertion holes fa and P of one printed circuit board P...

Insert the board insertion parts 2, 2...0 into the inside, and solder the protruding parts to connect them electrically.
At the edge of the other printed circuit board P, pins AQA bent at right angles are made to protrude downward and in all directions from the end surface through pin connectors C. The downward protruding parts are soldered and electrically oxidized. Leave it loose. In this state, the housing 6 is rotated to insert the protrusion in the end face direction of the piso A into the pin insertion hole 3a, and the pin contact pieces 3b are held together to electrically connect and hold.

Note that at this time, it is preferable to provide a locking mechanism (not shown) between the housing 5 and the pin connector C.

Fig. 5 shows a case where horizontal printed circuit boards P and P are connected.The difference from the one in Fig. 4 is that pin connectors C that are connected to the top and bottom are used, and the housing 5 is placed over the connectors. It is installed.

In the above usage example, since the movable plate 4 is movable in three directions (left and right, up and down, and front and back) by the vertical plate part 4a, horizontal plate part 4b, and pin insertion hole 3a, such a connection is possible and the printed circuit board This allows the positional deviation of P to be absorbed.

Since the present invention has the above-mentioned configuration, the fixed printed circuit boards P and P are connected not only by electric wires (some terminals are used), but also by a connector for connecting boards, rather than using a connector method using wires or press-fit terminals. Since it can be connected as a device, it is inexpensive and the mounting design of the device is not limited.

Moreover, the misalignment of the printed circuit boards P and P is absorbed by movement in three directions: up, down, left, right, and front and back, so it may become impossible to insert the pin A, or even if it is inserted, a strong force will be applied to the contact point. ``Furthermore, even after the printed circuit boards P and P are connected, slight movement is possible without causing contact failure.

Further, according to the third invention, the connector terminals 1, 1...
Since the starting ends of the board insertion parts 2, 2, ... are connected by the separator 6, in addition to the above effect, the work of inserting the connector terminals 1, 1, ... into the printed circuit board P can be done all at once. , and can be done easily.

Furthermore, if the housing 5 and the separator 6 are configured integrally via the connecting portions 7, 7 and are cut out after storing the connector terminals 1, 1..., the connector terminals 1... There are various effects such as simplifying the storage work and reducing the number of parts.
