In the conventional connector, for example, when various functions are to be exhibited according to the mating part to be connected, the connector itself must be changed or the function must be changed by computer software.
When the connector itself is changed, there is a problem in that it is not convenient because a plurality of connectors must be provided for each function. Further, when dealing with computer software, there is a problem that it takes time to recognize each other's parts after connecting the connector.

  An object of the present invention is to provide a connector in which the function or the like of the terminal can be changed by not connecting the terminal.

In the first invention, one or a plurality of terminals are provided in each of the pair of connector bodies, and all or a part of the terminals of at least one connector body are in contact with the terminals of the other connector body, and the other The movable terminal can be moved according to the magnetic force between the non-contact position where it does not contact the terminal of the connector body, and the movable terminal has a magnetic force generated between the terminal of the other connector body facing the It is characterized in that the contact position or the non-contact position is maintained according to the magnetic force generated between the magnetic body corresponding to the opposing terminal.
The magnetic material corresponding to the terminal is, for example, a material in which the terminal is a non-magnetic material and the magnetic material is fixed to the non-magnetic terminal, or a magnetic material is associated with the non-magnetic terminal. It is a concept that includes.

  A second invention includes the movable terminal and a fixed terminal opposite to the movable terminal, wherein a spring force is applied to the movable terminal, and a contact position or a non-contact position with respect to the opposite fixed terminal by the action of the spring force. And either one of the movable terminal or the fixed terminal is a magnetic force generation source, and the other is a terminal made of a magnetic material or a terminal associated with the magnetic material, and the magnetic force generation source. When a magnetic force is generated between the one terminal and the other terminal made of magnetic material or the magnetic material associated with the other terminal, the movable terminal is in a non-contact position or against the spring force. It is characterized in that it is configured to move to the contact position.

A third invention includes the movable terminal and a fixed terminal opposite to the movable terminal, and a spring force is applied to the movable terminal, and a contact position or a non-contact position with respect to the opposite fixed terminal by the action of the spring force. A magnetic force generating source is associated with one of the movable terminal and the fixed terminal, and the other is configured with a terminal made of a magnetic material or a terminal associated with a magnetic material, When a magnetic force is generated between the magnetic force generation source associated with the terminal and the other terminal made of the magnetic material or the magnetic material associated with the other terminal, the movable terminal is non-resistant against the spring force. It is characterized in that it is configured to move to the contact position or the contact position.
In the second aspect of the invention, the terminal itself is a magnetic force generation source composed of a permanent magnet or an electromagnet. In the third aspect of the invention, the magnetic force generation source is associated with the terminal.

In the fourth aspect of the invention, both the movable terminal and the terminal facing the movable terminal are used as the magnetic force generation source, or both the movable terminal and the terminal facing the movable terminal are associated with the magnetic force generation source. Has characteristics.
The fifth invention is characterized in that either one of the movable terminal and the terminal facing the movable terminal is used as a magnetic force generation source, and the other terminal is associated with the magnetic force generation source.
The sixth invention is characterized in that the magnetic force generation source is an electromagnet.

According to the first to sixth inventions, since the movable terminal holds the contact position or the non-contact position with respect to the other terminal facing, the function of the connector can be varied depending on the physical position of the movable terminal. Can be changed.
Therefore, it is not necessary to provide a connector for each different function as in the prior art, and it is not necessary to change the function of the terminal with computer software. As a result, the convenience is improved, and the time for recognizing the mating parts from each other after connecting the connector is hardly required.

According to the second invention, since the terminal itself is a magnetic force generation source, the entire configuration can be simplified.
According to the third aspect of the invention, since the magnetic force generation source is associated with the terminal, the position where the magnetic force generation source is provided can be freely selected.
According to the fourth and fifth inventions, the terminals facing each other can control the contact position or the non-contact position by using the attractive force or repulsive force of the magnetic force generation source, so various terminal arrangements can be realized.

  According to the sixth aspect of the invention, since the movable terminal can be kept in the contact position or the non-contact position by not exciting the electromagnet, the excitation and de-excitation of the electromagnet can be controlled by computer software. Many functions can be freely set in one connector.

In the first embodiment shown in FIGS. 1 and 2, the terminal of one connector body A is a movable terminal a and the terminal of the other connector body B is a fixed terminal made of a magnetic material. b.
The connector body A is provided with a terminal incorporating hole 1 and the movable terminal a is incorporated in the terminal incorporating hole 1 so as to be movable. And this movable terminal a consists of the pin a1 and the flange a2, and at least the pin a1 is comprised with the magnetic body which has electroconductivity.

  Further, the flange a2 of the movable terminal a is provided in the terminal incorporating hole 1, and a spring 3 is interposed between the flange a2 and the stopper part 2 provided in the opening of the terminal incorporating hole 1, The movable terminal a is kept at the non-contact position shown in FIG. 2 by the spring force of the spring 3. The movable terminal a moves against the spring force of the spring 3 and can move to a contact position where it comes into contact with the fixed terminal b.

The pin a1 of the movable terminal a as described above is provided with the electromagnetic coil 4, and both ends of the electromagnetic coil 4 are connected to a control means (not shown) for controlling the current. The pin a1 can be converted to an electromagnet by passing a current through the electromagnetic coil 4 thus configured.
In the figure, reference numeral 5 is a lead wire for a movable terminal, and 6 is a lead wire for a fixed terminal.

The connector bodies A and B configured as described above are connected to each other as shown in FIG. 1 so that the movable terminal a and the fixed terminal b face each other. At this time, if a current is supplied to the electromagnetic coil of the specific movable terminal, the movable terminal becomes an electromagnet and is attracted to and contacts the fixed terminal b which is a magnetic body. That is, the movable terminal a moves to the contact position against the spring force of the spring 3 by the action of the magnetic force generated between the movable terminal a and the fixed terminal b.
Therefore, by arranging whether or not current is supplied to the electromagnetic coil 4 by the current control means, it is possible to freely set the arrangement relationship between the movable terminal a that contacts the fixed terminal b and the one that does not. it can.

In the first embodiment, the fixed terminal b may be configured with a permanent magnet. In this case, an attractive force or a repulsive force is generated according to the polarity of the movable terminal a and the polarity of the permanent magnet that is the fixed terminal b. When an attractive force acts between the movable terminal a and the fixed terminal b, the movable terminal a moves to the contact position, and the two firmly contact the magnet by the attractive force. Further, when a repulsive force acts between the movable terminal a and the fixed terminal b, the movable terminal a remains in the non-contact position shown in the figure.
Therefore, according to the direction of the current of the movable terminal a, it is possible to freely set the arrangement relationship between the movable terminal a that contacts the fixed terminal b and the one that does not.

In the second embodiment shown in FIG. 3, the fixed terminal b is made of a non-magnetic material, and a magnetic material is provided around the fixed terminal b. That is, the magnetic body m is associated with the fixed terminal b. Other configurations are the same as those in the first embodiment.
In addition, the magnetic body m matched with the said fixed terminal b should just be matched in the positional relationship which generates an attractive force between the movable terminals a which oppose. Therefore, instead of providing the magnetic body m around the fixed terminal b as shown, for example, a magnetic body may be provided directly behind the fixed terminal b.

The third embodiment shown in FIG. 4 is that the iron core 7 is brought into contact with the fixed terminal b, the electromagnetic coil 8 is provided on the iron core 7, and the movable terminal a is made of a magnetic material not provided with the electromagnetic coil 4. Unlike the first embodiment, the rest of the configuration is the same as that of the first embodiment.
In the third embodiment, the movable terminal a must be a magnetic material, but the fixed terminal b may be a magnetic material or a non-magnetic material. However, in the case of being made of a nonmagnetic material, it is necessary to have at least magnetic permeability.

Also in the third embodiment, the movable terminals a and the fixed terminals b face each other by connecting the connector bodies A and B to each other. At this time, if a current is supplied to the electromagnetic coil of the necessary fixed terminal, the fixed terminal becomes an electromagnet, and the movable terminal a, which is a magnetic body, comes into contact with the fixed terminal b while being attracted. In other words, the movable terminal a moves to the contact position against the spring force of the spring 3 by the action of the magnetic force generated between the movable terminal a and the fixed terminal b.
Therefore, by arranging whether or not current is supplied to the electromagnetic coil 8 by the current control means, it is possible to freely set the arrangement relationship between the movable terminal a that contacts the fixed terminal b and the movable terminal a that does not. it can.

In the third embodiment as well, the movable terminal a can be formed of a permanent magnet. In this case, as described above, attraction or repulsion is generated according to the polarity of the movable terminal a that is a permanent magnet and the polarity of the fixed terminal b that is an electromagnet. When an attractive force acts between the movable terminal a and the fixed terminal b, the movable terminal a moves to the contact position, and the two firmly contact the magnet by the attractive force. Further, when a repulsive force acts between the movable terminal a and the fixed terminal b, the movable terminal a remains in the non-contact position shown in the figure.
Therefore, according to the direction of the current of the movable terminal a, it is possible to freely set the arrangement relationship between the movable terminal a that contacts the fixed terminal b and the one that does not.

In the fourth embodiment shown in FIG. 5, the spring 3 is interposed between the flange a2 of the movable terminal a and the bottom of the terminal assembly hole 1 facing the flange a2, so that the movable terminal a is always kept in the contact position. I am doing so. An electromagnetic coil 4 is provided on the flange a2 side of the movable terminal a, and the electromagnetic coil 4 is connected to current control means (not shown) for controlling the current and the direction of the current.
On the other hand, an iron core 7 is brought into contact with the fixed terminal b, and an electromagnetic coil 8 is provided on the iron core 7, and the electromagnetic coil 8 controls a current and a direction of the current different from the above-described current control that is not shown. Connected to the means.

  Therefore, whether or not to supply current to the electromagnetic coil 4 or 8 can be controlled by separate current control means, and the direction of the current can also be controlled. And since attractive force or repulsive force can act between the movable terminal a and the fixed terminal b according to the direction of electric current, if attractive force acts between both, both terminals will maintain the state which contacted, and repulsive force When the actuates, the movable terminal a retreats to the non-contact position against the spring force of the spring 3.

  In the above case, if the contact state of both terminals is maintained only by the spring force of the spring 3, it is not necessary to supply current to the electromagnetic coils 4 and 8. However, in order to ensure contact between the two, it is better to generate an attractive force between both terminals. In any case, whether or not an attractive force is required between both terminals is determined depending on how the spring force of the spring 3 is set. In some cases, the movable terminal a may be moved to the contact position or the non-contact position with respect to the fixed terminal b by only the attractive force and the repulsive force between the two terminals without providing the spring 3.

Moreover, in this 4th Embodiment, although the electromagnetic coil 4 was provided in the flange a2 side, naturally it may be provided in the pin a1 side.
Furthermore, in the fourth embodiment, either the movable terminal a or the fixed terminal b may be an electromagnet, and the other may be a permanent magnet. In this case, an attractive force or a repulsive force can be generated according to the polarity of the electromagnet and the polarity of the permanent magnet, and the arrangement relationship between the movable terminal a and the fixed terminal b can be freely set according to the polarity. What can be done is as described above.

  In addition, it is not necessary to provide the magnetic generation source in each said embodiment directly in a terminal. As long as it is associated with the terminal and can be magnetized, the magnetic source and the terminal may be physically separated. In short, it is only necessary to generate an attractive force or repulsive force that moves the movable terminal a between the movable terminal a and the fixed terminal b facing each other.

In the fifth embodiment shown in FIG. 6, each of the movable terminal a and the fixed terminal b is constituted by a permanent magnet, and one of the pair of connector bodies A and B is connected to the movable terminal a. The terminal of the other connector body B is a fixed terminal b, and both the terminals are made of permanent magnets.
The configuration in which the movable terminal a is movable and the configuration in which the spring 3 is arranged are the same as those in the first embodiment.

In the fifth embodiment as described above, for example, the tip of the movable terminal a made of a permanent magnet, that is, the contact end is unified to one of the S and N poles, and the S or N pole is fixed on the fixed terminal b side. If the arrangement is different, the arrangement relationship between the movable terminal a and the fixed terminal b can be set in various modes.
It is also possible to make all the terminals of both connector bodies A and B movable terminals made of permanent magnets. In this case, the arrangement relationship between the movable terminal a and the fixed terminal b can be set in various modes according to the polarities of the tips of both movable terminals.

Furthermore, all the movable terminals or fixed terminals of one connector body are made permanent magnets, and the polarity is unified to either polarity, and the fixed terminals or movable terminals of the other connector body are unified only where necessary. In addition, a magnet having a polarity opposite to the above polarity may be used, and terminals other than necessary portions may be made of a nonmagnetic material.
Further, when a permanent magnet is used, the permanent magnet and the terminal may be physically separated without using the terminal itself as a magnet. In short, it is only necessary to generate an attractive force or a repulsive force that moves the movable terminal between the movable terminal a and the fixed terminal b facing each other.
