Description

Span joints and tools for span joints

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

For electrical circuit switching and setting changes, jumpers are mostly used. In recent years, with the progress of narrower pitch and miniaturization of circuits, the miniaturization (miniaturization) of the cross-connector has been developed. As a result, the operation of the jumper (holding the jumper to move it, or attaching and detaching the pin header) is not easy.

An example of a technology related to a miniaturized cross-connector is disclosed in PTL 1. The short-circuit connector of PTL 1 is arranged in a housing made of insulating material. Furthermore, the short-circuit connector includes a pair of conductor pieces that clamp the two pins of the header from the side. As a result of the above structure, the short-circuit connector of PTL 1 can be miniaturized. However, when the short-circuit connector of PTL 1 is miniaturized (especially miniaturized), the short-circuit connector is not grasped (falling off) or installed incorrectly (installation position error) in the operation of the short-circuit connector performed by human hands or robots. Or the problem caused by the disadvantages such as settlement caused by the overload of the docking point. Especially in the production process and inspection process, when the circuit switching and setting changes of multiple jumpers are performed, when the disadvantages such as falling off or wrong installation position occur, in order to cope with the disadvantages, there is a problem of a significant increase in man-hours.

Another example of the technology related to the miniaturized cross-connector 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 that can be inserted into and clamped by two pins provided on the electronic circuit board from the first direction, and are formed on the same plane as the first pair of tubes and are separated from the first tube. A pair of second tubes can be clamped by inserting 2 pins in the second direction perpendicular to the direction. That is, each of a pair of first pipes crosses each of a pair of second pipes. The part of the first pair of tubes from the insertion hole of one of the tubes to the position where it first intersects with one of the second tubes is made of a conductor. The part between the two positions of the second tube that intersects with the first tube and the first tube in the pair of second tubes is made of a conductor is made of electric conductor. As a result of the above structure, the PTL 2 plug can be miniaturized. However, when the plug of PTL 2 is miniaturized (especially miniaturized), as with the technology of PTL 1, it is not easy to operate the plug with a human hand or a robot.

Another example of the technology related to the miniaturized cross-connector is disclosed in PTL 3. The plug connector of PTL 3 has contact elements arranged in a row in the cavity of the plastic shell. One end of the contact element has a first connection part, and the opposite side has a second connection part and a pair of spring tongues. The plug connector has a gap that can be approached from the side in the joint area between the two connection parts of the contact element, especially the insulation removal contact and the pair of spring tongues. By pressing the short-circuit bridge laterally into the gap of the two contact elements, the two contact elements are electrically connected. As a result of the above structure, in the plug connector of PTL 3, the short-circuit bridge can be miniaturized. However, when the short-circuit bridge of PTL 3 is miniaturized (especially miniaturized), similar to the technology of PTL 1, it is not easy to operate the plug connector used by human hands or robots.

An example of a technique for improving the operation of the cross joint 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 a certain interval. The connector has a conductive sheet that can selectively short-circuit a pair of adjacent terminal pins, and the conductive sheet is housed in an electrically insulating cylindrical box. The conductive sheet has a clamping sheet, a bridging sheet and a locking sheet. The clamping piece extends in a plane direction including the axis of a pair of terminal pins to clamp the terminal pins. The bridge piece connects the clamping pieces into one body. The locking piece is a plate that is protrudingly provided on the bridge piece and is engaged with a hook-shaped jig when the connector is unplugged from the terminal pin. As a result of the above structure, the PTL 4 connector can be easily operated (unplugged). However, when the connector of PTL 4 is miniaturized (especially miniaturized), there is a problem that operations (movement, installation, etc.) other than the removal of the connector are not easy.

Another example of the technology for improving the operation of the cross-connector is disclosed in PTL 5. In the short-circuit connector of PTL 5, a gripping part is formed on the upper surface of the short-circuit connector body. Since the gripping part has a cut in the part connected to the short-circuit connector body, it can be folded off from the short-circuit connector body. As a result of the above structure, the short-circuit connector of PTL 5 can achieve both miniaturization and ease of operation. [Prior technical literature] [Patent Literature]

[The problem that the invention wants to solve]

However, in the short-circuit connector of PTL 5, when the short-circuit connector is miniaturized (especially miniaturized) (after the grip portion is broken), there is a problem that the ease of operation of the short-circuit connector is lost. For example, in the short-circuit connector of PTL 5, it is not easy to re-install (unplug, move, install) the short-circuit connector after the grip is broken.

The present invention is made in view of the above-mentioned problems, and its main purpose is to balance the miniaturization and easy operation of the cross joint. [Means to Solve the Problem]

[Form to implement the invention]

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

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

Fig. 1 is a perspective view showing an example of the structure of a cross joint according to the first embodiment of the present invention. However, in Fig. 1, the front part of the shell of the jumper is shown in perspective, and the inside of the jumper is visually recognizable (the same is true in other figures). In addition, the direction in which the jumper of the present embodiment is provided is arbitrary, and in the following description, the Z-axis direction in FIG. 1 is described as being upward (the same applies to other drawings).

As shown in FIG. 1, the jumper 1 of this embodiment includes a housing 5 and a conductor 9.

The conductor part 9 is formed of an electric conductor, and is provided in the housing 5. The conductor part 9 has two crossover points 2, 3, and one jig locking part 4.

The housing 5 (molded) is formed of an electrical insulator or a conductor, and holds the conductor portion 9. The housing 5 has a cylindrical shape. The housing 5 has an open upper bottom surface and a lower bottom surface formed with through holes into which two terminals (pins) arranged side by side on the pin header 6 can be inserted.

The 2 jumper points 2 and 3 can be arranged side by side on the 2 terminals (pins) of the header 6 to be individually plugged and unplugged. The conductor part 9 electrically conducts (short-circuits) the two terminals when the two terminals arranged side by side on the pin header 6 are locked. The two crossover points 2 and 3 are plate springs biased toward the inner wall of the housing 5. By clamping the two terminals by the biased crossover points 2, 3 and the inner wall of the housing 5, the two terminals are locked in a pluggable manner.

The jig tool locking part 4 locks the jig tool 7 for the cross joint in a pluggable manner. Here, the cross-connector tool 7 is a tool used to install or remove the cross-connector 1 to two terminals arranged side by side on the header 6. The cross-joint tool 7 can be operated manually or by machines such as robots. The span joint tool 7 has a size sufficient to handle the span joint 1. Here, the operation refers to grasping the jumper 1 to move it, or attaching and detaching the pin header. The upper part of the conductor part 9 has a hook-shaped tool locking part 4 which is a plate spring biased toward the inner wall of the housing 5. By using the biased clamping part 4 of the clamping tool and the inner wall of the housing 5 to clamp the clamping tool 7 for the cross-connector, the clamping tool 7 for the cross-connector can be locked in a pluggable manner. Here, the insertion and removal direction of the jig tool 7 for the jumper of the jig tool locking portion 4 is parallel to the insertion and removal direction of the two terminals arranged side by side on the pin header 6 at the two jumper points 2, 3.

The operation of this embodiment will be explained.

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

As shown in FIG. 2, inserting the spanner joint tool 7 into the spanner joint 1, and by operating the spanner joint tool 7, the user can easily operate (move) the spanner joint 1 by manual work or the like. Since the clamping part 4 of the clamping tool clamps the clamping tool 7 for the cross joint, the user or the robot does not need to hold the joint 1, as long as the clamping tool 7 for the cross joint 7 is of a size that the user or the robot can easily hold. Even if the cross joint 1 is miniaturized, it is easy to operate.

Fig. 3 is a perspective view illustrating the operation (installation) of a jig tool for a cross joint using the first embodiment of the present invention.

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

The holding force of the 2 jumper points 2 and 3 in the plug-in direction can be achieved by making the 2 terminals or jumper points arranged side by side at the contact positions of the 2 terminals of the header 6 and the 2 jumper points 2, 3 2, 3 surface properties or elasticity changes to be adjusted. The holding force in the plugging and unplugging direction of the clamping part 4 of the jig can be made by making the surface of the jig 7 or the jig 4 at the contact position between the jig 7 and the jig 4 The nature state or elasticity changes to be adjusted. For example, by changing the spring performance (spring constant) of the spring part of the cross-over point 2, 3 or the clamping part 4 of the tool, the holding force in the plug-in direction can be adjusted. Or, by changing the friction coefficient (depending on the type of plating, etc.) of the jumper points 2, 3, the spring part of the clamping part 4 of the jig tool, or the clamping part of the jig 7 The holding power.

For example, the holding force F2 in the plugging and unplugging direction of the clamping part 4 of the tool is set to be much larger than the value of gravity caused by the weight of the jumper 1. At this time, by operating the spanner tool 7 in the state where the spanner tool 7 is engaged with the spanner 1, the spanner 1 can be installed on the pin header 6.

In addition, for example, the holding force F2 of the plug-in direction of the clamping part 4 of the tool is set to a value much larger than the sum of the holding forces F1 of the two cross-over points 2 and 3 in the plug-in direction. At this time, by operating the jumper fixing tool 7 in a state where the jumper fixing tool 7 is engaged with the jumper 1, the jumper 1 can be removed from the pin header 6.

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

A description will be given of a modification of this embodiment.

In this modified example, the holding force F2 in the insertion and extraction direction of the tool locking portion 4 is set to a value smaller than the sum of the holding forces F1 in the insertion and extraction directions of the two crossover points 2 and 3. However, the holding force F2 is much greater than the value of gravity caused by the weight of the span joint 1.

In this modified example, the jumper 1 can be installed on the header 6 by operating the jumper fixing tool 7 in a state where the jumper fixing tool 7 is locked to the jumper 1. Furthermore, when the jig tool 7 for the jumper is operated to separate from the pin header 6, the jig tool 7 for the jumper can be automatically removed from the jumper 1.

Therefore, this modification has an effect of further improving the ease of operation when attaching the jumper 1 to the pin header 6.

(Second Embodiment) Next, the second embodiment of the present invention based on the first embodiment of the present invention will be described. The jig tool for the cross joint of this embodiment has a detector function.

Fig. 4 is a perspective view showing an example of the structure of a cross joint according to the second embodiment of the present invention.

As shown in FIG. 4, the probe 8 is a probe which has the function of the jig tool 7 for the jumper of the first embodiment and can input the voltage of the jig locking part 4. The probe 8 is used as a detection terminal such as a tester.

As described above, the present embodiment has the effect of improving the ease of operation in the inspection of the voltage or signal of the tool engagement portion 4.

(Third Embodiment) Next, the third embodiment of the present invention, which is the basis of the various embodiments of the present invention, will be described.

Fig. 5 is a perspective view showing an example of the structure of a cross joint according to the third embodiment of the present invention.

As shown in FIG. 5, the jumper 11 of the present embodiment includes a jumper point 12 and a tool locking portion 14.

The jumper point 12 makes the two terminals electrically conductive when the two terminals arranged side by side on the pin header 6 are locked in a pluggable manner.

The jig tool locking portion 14 locks the jig tool 7 for the cross joint in a pluggable manner.

The tool 7 for the jumper is a tool for installing or removing the two terminals of the jumper 12.

As described above, in the jumper 11 of this embodiment, if the jumper point 12 is locked to the two terminals arranged side by side on the pin header 6, the two terminals are short-circuited. Furthermore, in the jumper 11 of the present embodiment, the jumper 11 can be operated by operating the jumper tool 7 in a state where the jumper tool 7 is locked to the tool locking portion 14. Furthermore, since the tool locking portion 14 clamps the cross-joint tool 7, the user or the robot does not need to hold the cross-joint 11, as long as the cross-joint tool 7 is easy to hold by the user or the robot. The size, even if the cross joint 11 is miniaturized, it is easy to handle. Therefore, the jumper 11 of the present embodiment has the effect of achieving both miniaturization and ease of operation in the jumper.

In the above, the present invention has been described with reference to the embodiments (examples), and the present invention is not limited to the above-mentioned embodiments (and examples). Various changes can be made to the structure and details of the present invention that are within the scope of the present invention and understandable by the industry. [Industrial availability]
