Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a female connector that can be connected to male contact pins regularly planted in two rows in parallel in through holes of a printed wiring board (hereinafter referred to as a backboard).

[Prior Art] Conventionally, in order to detect signals from male contact pins installed in two parallel rows in through-holes of a backboard, wires were wrapped or soldered to the male contact pins and detected. Alternatively, detection was performed by inserting a female contact.

[Problem that the invention attempts to solve]

However, among the conventional methods described above, the method of connecting electric wires has the problem that the male contact pin must be wrapped or soldered every time a signal is detected, which increases the number of man-hours and costs. be.

In addition, with the method of using female contacts, there is a limit to the number of times they can be used as a connector, so the female contacts must be replaced frequently, which requires a large amount of man-hours and costs to replace the female contacts. There is a problem. Furthermore, the use of female contacts limits the number of times the male contact pins can be used as connectors, which is undesirable.

In view of the above problems, the present invention aims to provide a connector with excellent operability, reliability, and longevity.

[Means for solving problems]

The present invention provides a female connector that can be connected to a plurality of male contact pins installed in two rows in parallel in through holes of a printed wiring board, and has a structure for detecting signals from the male contact pins with a recess into which the male contact pins are fitted. A contact with continuous grooves on both sides, an insulating guide member that is inserted between rows of male contact pins using the grooves to guide them in alignment, and a contactor that makes contact with the male contact pins. a spring with the same pitch as the arrangement of the male contact pins;
A pair of connecting members are rotatably attached to the guide member so that the contact spring faces the concave groove of the guide member from both sides with the guide member sandwiched therebetween; The contact spring is characterized by comprising a spring member that presses the contact spring into contact with the male contact pin when biased.

[Effect]

With the above configuration, in the present invention, when the guide member is inserted between the rows of male contact pins with the biasing of the spring member released, and the spring member biases the end of the connecting member outward again, A contact spring presses into contact with the male contact pins that are aligned and guided by the grooves of the guide member, and each of the male contact pins can make an electrical connection at the contact point of the contact spring.

Also, by reversing the above connection procedure,
Electrical connections can be broken.

That is, when inserting and removing the guide member, by releasing the bias of the spring member, there is no pressing force of the contact spring against the male contact pin, so electrical connection or disconnection can be repeated without any insertion or removal force. I can do it.

〔Example〕

Examples will be described below with reference to the drawings.

Figure 1 is a plan view showing one embodiment of the present invention;
The figure is a perspective view of the same, and in the figure, 1 is a female connector of the present invention, 2 is a back board, 3 is a through hole 4 of the back board, which is implanted in two rows at equal pitches,
The female connector 1 is a male contact pin for detecting a signal.

The configuration of the female connector 1 will be explained below.

In the figure, reference numeral 5 denotes a main body guide made of an insulator such as synthetic resin, and a concave groove 6 for receiving a male contact pin 3 implanted in the back board 2 is provided at the tip of the main body guide 5 for the male contact. pin 3
There are multiple locations corresponding to the following. Further, a hole 8 larger than the diameter of the coil spring 7 is provided at the rear end to allow the coil spring 7 to escape.

Reference numeral 9 denotes a set of two main bodies made of an insulator such as synthetic resin, and the main body 9 is rotatably attached to the main body guide 5 with the main body guide 5 sandwiched therebetween, with a shaft 10 serving as a common shaft of the two pieces. It is being

On the inner surface of the tip of the main body 9, contact springs 11 for detecting signals from the male contact pins 3 are arranged at equal pitches to the male contact pins 3.
12 is made of an insulator, and the contact spring 11 is connected to the main body 9.
This is a contact spring holding plate that is fixed to each. On the other hand, a coil spring 7 is attached to the rear end of the main body 9, and by letting this coil spring 7 into the hole 8 of the main body guide 5, a repulsive force is generated in the direction of the arrow, which causes the male contact The contact spring 11 comes into pressure contact with the pin 3. That is, the female connector 1 is configured to form a clip with the contact spring 11 at the tip.

Further, the contact spring 11 is attached to the main body 9 with its tip part lifted by δ (~1 mm), as shown in the plan view of the main part in FIG. 3a. As a result, even if there are variations in the dimensions of the male contact pin 3, contact spring 11, etc. after it is attached to the male contact pin 3 as shown in FIG. connections are possible.

At the tip of the contact spring 11, there is a sharp and hard contact 1.
3 is welded, and on the other side, cable 14 is welded.
are connected by soldering. This cable 14 is firmly fixed to the main body 9 by a cable clamp 15 using screws or the like.

The operation of this embodiment with the above configuration will be explained.

FIG. 4a is a plan view showing this embodiment before it is installed, and FIG. 4b is a plan view showing it when it is installed.

First, as shown in FIG. 4a, the cable end of the main body 9 of the female connector 1 is held between fingers, and the spring is displaced to open the tip.

In this state, insert the tip of the main body guide 5 between the two rows of male contact pins 3 so that the male contact pins are regularly and accurately fitted into the grooves 6, and the leading edge of the main body guide 5 is connected to the back board 2. When the contact spring 11 touches the male contact pin 3, the force of the finger is relaxed and the contact 13 of the contact spring 11 is pressed into contact with the male contact pin 3 by the repulsive force of the coil spring 7, as shown in FIG. 4b.

As a result of the above, the male contact pin 3 is connected to the contact spring 1.
Electrically connect to 1.

When removing the female connector 1 from the male contact pins 3, the above-mentioned mounting procedure may be reversed.
That is, pinch the cable end side of the main body 9 with your fingers,
After displacing the coil spring 7 to open the tip and release the pressing contact, the tip of the main body guide 5 fitted with the male contact pin 3 may be pulled out while maintaining that state.

Note that the contact position can be easily adjusted by using a body guide 5 whose length from the shaft 10 to the tip is changed.

[Effect of idea]

As explained in detail above, according to the present invention, a female connector connectable to a plurality of male contact pins installed in two rows in parallel in through holes of a printed wiring board has a structure for detecting signals from the male contact pins. , by using a clip-shaped female connector that inserts the two rows of male contacts at once through an insulating guide member that aligns and guides them, and presses and connects the mounted contact springs to the male contacts. The connector can be inserted and removed without applying any pressing force by releasing the bias of the clip, thereby realizing a connector that requires no insertion or removal force.

As a result, it is possible to provide a connector with excellent operability, reliability, and long life.
