Description

Jumper and jumper tool

The present invention relates to a technology for a jumper that short-circuits two terminals of a header.

In applications such as circuit switching and setting change of electrical appliances, jumpers are mostly used. In recent years, with the progress of narrower pitch and miniaturization of circuits, the miniaturization (miniaturization) of cross-connectors has been developed. As a result, the operation of the cross-connector (holding the cross-connector to move it, or loading and unloading the pin) is not easy.

An example of a miniaturized cross-linker technology is disclosed in PTL 1. The short-circuit connector of PTL 1 is provided in a case formed of an insulating material. Furthermore, the short-circuit connector includes a pair of conductor pieces that sandwich the two pins of the pin from the side. As a result of the above structure, the short-circuit joint of PTL 1 can be miniaturized. However, when miniaturizing (especially miniaturizing) the short-circuit joints of PTL 1, the operation of the short-circuit joints performed by human hands or robots has not been grasped (fall off), and incorrectly installed (wrong installation position). Or problems caused by the settlement caused by the overload of the butt joints. Especially in the production process and inspection process, when the circuit switching and setting changes of multiple cross-connectors are performed, when the disadvantages such as falling off or incorrect installation position occur, there is a problem that the working hours increase significantly due to the disadvantages.

Another example of miniaturized cross-linker technology is disclosed in PTL 2. The plug of PTL 2 is formed in a non-conductive body. In addition, the plug includes a pair of first tubes which are inserted into the two pins provided on the electronic circuit board from the first direction and can be held therebetween, and a pair of first tubes which are formed in the same plane as the pair of first tubes, A pair of second tubes that can be clamped by inserting two pins in a second direction that is perpendicular. That is, each pair of the first tube and each pair of the second tube intersect. A pair of first tubes is made of a conductor from an insertion hole of one of the tubes to a position where it first crosses one of the second tubes. Among the pair of second tubes, the portion between the second tube and the first tube that intersects the first tube is made of a conductive material. As a result of the above structure, the plug of the PTL 2 can be miniaturized. However, when the plug of PTL 2 is miniaturized (especially miniaturized), as with the technology of PTL 1, the operation of the plug performed by a human hand or a robot is not easy.

Another example of miniaturized cross-linker technology is disclosed in PTL 3. The plug connector of PTL 3 has contact elements arranged in a row in the cavity of the plastic case. One end of the contact element has a first connection portion, and the opposite side has a second connection portion and a pair of spring tongues. The plug connector has a notch that can be approached from the side in the two connecting parts of the contact element, especially the joint area between the insulation removal contact and the pair of spring tongues. By pushing the short-circuit bridge laterally to the gap of the two contact elements, the two contact elements are electrically conducted. As a result of the above structure, in the plug connector of the PTL 3, the short-circuit bridge can be miniaturized. However, when the short-circuit bridge of PTL 3 is miniaturized (especially miniaturized), as with the technology of PTL 1, the operation of plug connectors performed by human hands or robots is not easy.

An example of cross-connect technology for improved handling is disclosed in PTL 4. The connector (switch) of PTL 4 includes a plurality of terminal pins and connectors. A plurality of terminal pins are implanted into the electrically insulating base at regular intervals. The connector has a conductive sheet that can selectively short-circuit one pair of adjacent terminal pins, and the conductive sheet is housed in an electrically insulating cylindrical box. The conductive sheet includes a clamping sheet, a bridge sheet, and a locking sheet. The clamping piece extends in a plane direction including an axis of a pair of terminal pins to clamp the terminal pins. The bridging piece connects each of the holding pieces into one body. The locking piece is a plate protruding from the bridge piece and engaging with a hook-shaped jig when the connector is pulled out from the terminal pin. As a result of the above structure, the joint of the PTL 4 can be easily operated (removed). However, when the connector of PTL 4 is miniaturized (especially miniaturized), there are problems that it is not easy to perform operations (moving, installing, etc.) other than removing the connector.

Another example of cross-connect technology for improved handling is disclosed in PTL 5. A shorting joint of PTL 5 has a grip portion formed on the shorting joint body. Since the grip portion has a cutout at a portion connected to the short-circuited joint body, it can be folded away from the short-circuited joint body. As a result of the above structure, miniaturization and ease of operation can be achieved in the short-circuit joint of PTL 5.

[Problems to be Solved by Invention]

However, in the short-circuit joints of PTL 5, when the short-circuit joints are miniaturized (especially miniaturized) (after the gripping portion is folded), there is a problem that the ease of operation of the short-circuit joints is lost. For example, in the short-circuit joint of PTL 5, it is not easy to re-install (remove, move, install) the short-circuit joint after the grip part is folded off.

[Forms for Implementing Invention]

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in all drawings, the same constituent elements are assigned the same reference numerals, and descriptions thereof are appropriately omitted.

(First Embodiment)
The structure of this embodiment will be described.

FIG. 1 is a perspective view showing an example of the structure of a cross-connector according to the first embodiment of the present invention. However, in FIG. 1, a front part of the shell of the jumper is seen through and the inside of the jumper is visually recognizable (the same is true in other figures). It should be noted that the direction of setting the cross joint of this embodiment is arbitrary, and in the following description, the Z-axis direction in FIG. 1 will be described as the upper direction (the same applies to other drawings).

As shown in FIG. 1, the cross joint 1 of this embodiment includes a case 5 and a conductor portion 9.

The conductor portion 9 is formed of a conductor and is provided in the case 5. The conductor portion 9 includes two jumper points 2 and 3 and a jig locking portion 4.

The case 5 (molded) is formed of an electric insulator or a conductor, and holds the conductor portion 9. The casing 5 has a cylindrical shape. The casing 5 has an open upper bottom surface and a lower bottom surface formed with a through hole that can be inserted into two terminals (pins) of the pin 6 arranged side by side.

The two jumper points 2 and 3 can be installed side by side on the two terminals (pins) of the pin 6 to be individually inserted and locked. The conductor portion 9 electrically connects (short-circuits) the two terminals to each other when the two terminals of the pin 6 are locked and arranged side by side. The two bridge points 2 and 3 are plate springs that are biased toward the inner wall of the casing 5. The two terminals clamped by the biased junction points 2 and 3 and the inner wall of the housing 5 lock the two terminals in a pluggable manner.

The jig locking portion 4 locks the cross joint jig 7 in a pluggable manner. Here, the jumper treatment tool 7 is a treatment tool for installing or removing the jumper 1 on two terminals arranged side by side on the row pin 6. The cross-joint treatment tool 7 can be operated manually, and can also be operated by a robot or the like. The jumper treatment tool 7 has a size sufficient to operate the jumper 1. Here, the operation refers to grasping the cross-connector 1 to move it, or attaching and detaching the pin. The upper portion of the conductor portion 9 is provided with a hook-shaped jig locking portion 4 and is a plate spring biased toward the inner wall of the casing 5. The clamping tool fixing portion 4 and the inner wall of the housing 5 are clamped by the biasing tool fixing portion 4 to lock the clamping tool 7 in a pluggable manner. Here, the inserting / removing direction of the cross-connecting fixture 7 of the fixture locking portion 4 is parallel to the inserting / removing direction of the two terminals provided side by side at the two jumper points 2 and 3 on the pin 6.

The operation of this embodiment will be described.

FIG. 2 is a perspective view illustrating the operation (movement) of a jumper treatment tool using the jumper of the first embodiment of the present invention. However, in FIG. 2, for easy understanding, the cross-connector is enlarged and displayed relative to a human hand.

As shown in FIG. 2, the jumper tool 7 is inserted into the jumper 1. By operating the jumper tool 7, the user can easily operate (move) the jumper 1 by manual operation or the like. Since the jumper fixing tool 7 is held by the stopper locking portion 4, the user or robot does not need to hold the jumper 1, as long as the jumper cleaning tool 7 is a size that can be easily held by the user or the robot, Even if the jumper 1 is miniaturized, it is easy to handle.

Fig. 3 is a perspective view illustrating the operation (installation) of a cross-junction treatment tool using the cross-junction according to the first embodiment of the present invention.

As shown in FIG. 3, the user can easily operate (install) the jumper 1 to the pin 6 by operating the jumper treatment tool 7. After the user operates (installs) the jumper 1 to the pin 6, the user removes the jumper treatment tool 7 from the jumper 1.

The holding force of the two jumper points 2 and 3 in the inserting and pulling direction can be achieved by making two terminals or jumper points in contact positions of the two terminals arranged side by side on the pin 6 and the two jumper points 2 and 3 Adjust the surface property state or elasticity of 2 and 3. The holding force in the inserting / removing direction of the fixing tool locking portion 4 can be achieved by making the surface of the fixing tool fixing tool 7 or the fixing tool locking portion 4 at the contact position between the fixing tool fixing tool 7 and the fixing tool locking portion 4 Change in nature or elasticity. For example, by changing the spring performance (spring constant) of the spring portion of the jumper points 2, 3 or the tool locking portion 4, the holding force in the insertion / removal direction can be adjusted. Alternatively, by changing the friction coefficient (depending on the type of plating, etc.) of the spring portion of the jumper points 2, 3, the tool lock portion 4, or the lock portion of the jumper tool 7, the insertion direction can be adjusted Retention.

For example, the holding force F2 in the insertion / removal direction of the jig locking portion 4 is set to a value much larger than the gravity caused by the own weight of the cross joint 1. At this time, the jumper tool 7 can be mounted on the pin 6 by operating the jumper tool 7 while the jumper tool 7 is engaged with the jumper 1.

In addition, for example, the holding force F2 in the inserting / removing direction of the tool locking portion 4 is set to a value much larger than the sum F1 of the holding forces in the inserting / removing directions of the two bridge points 2 and 3. At this time, by operating the jumper tool 7 while the jumper tool 7 is engaged with the jumper 1, the jumper 1 can be removed from the pin 6.

As described above, in the cross connector 1 of this embodiment, if the two jumper points 2 and 3 are locked to the two terminals arranged side by side on the pin 6, the two terminals can be short-circuited. Further, in the cross-connector 1 of the present embodiment, the cross-connector 1 can be operated by operating the cross-connector treatment tool 7 with the cross-connector treatment tool 7 locked on the tool-locking portion 4. In addition, since the jumper fixing tool 7 is held by the stopper locking portion 4, the user or the robot does not need to hold the jumper 1 as long as the jumper fixing tool 7 is a size that the user or the robot can easily hold. Even if the cross-connector 1 is miniaturized, it is easy to operate. Therefore, the cross joint 1 of this embodiment has the effect of achieving both miniaturization and ease of operation.

A modification of this embodiment will be described.

In this modification, the holding force F2 in the inserting and pulling direction of the jig locking portion 4 is set to a value smaller than the sum F1 of the holding forces in the inserting and pulling directions of the two bridge points 2 and 3. However, the holding force F2 is much larger than the value of the gravity caused by the own weight of the cross joint 1.

In the present modification, the cross-connecting tool 7 can be mounted on the row pin 6 by operating the cross-connecting tool 7 while the cross-connecting tool 7 is locked on the cross-connecting device 1. When the jumper tool 7 is operated to be separated from the pin 6, the jumper tool 7 can be automatically removed from the jumper 1.

Therefore, this modification has the effect of further improving the ease of operation when the jumper 1 is mounted on the header 6.

The jumper treatment tool 7 is a treatment tool for installing or removing 12 pairs of 2 terminals of the jumper.

As described above, in the cross-connector 11 of this embodiment, the cross-connect point 12 is locked to the two terminals arranged side by side on the row pin 6, thereby short-circuiting between the two terminals. In addition, in the cross-connector 11 of the present embodiment, the cross-connector 11 can be operated by operating the cross-connector treatment tool 7 while the cross-connector treatment tool 7 is locked on the tool engagement portion 14. Furthermore, since the jumper fixing tool 7 is clamped by the stopper locking portion 14, the user or the robot does not need to hold the jumper 11, as long as the jumper cleaning tool 7 is easily held by the user or the robot The size is easy to handle even if the cross-connector 11 is miniaturized.
