Description

  The present invention relates to a cable connection jig used for connecting a cable to an electronic device such as a temperature controller attached to a control panel or the like.

In the control of mechanical equipment, various electronic devices such as a temperature controller and a timer are often centrally managed by arranging them in parallel on a control panel (for example, see Patent Document 1).
JP 11-354175 A

  When many electronic devices such as temperature controllers are arranged in parallel on the control panel, for example, when changing the setting contents, repeated key operations are required to change the setting by operating the keys on the front of the device. It becomes necessary and troublesome. In particular, when changing the setting contents of a large number of temperature controllers, a large amount of work is required for the setting change work.

  Therefore, there is a case where a setting tool such as a personal computer is connected to the temperature controller and means for inputting setting information input and set in advance to the setting tool to the temperature controller may be used. In this case, it is necessary to connect the setting tool and the temperature controller with a cable such as a USB cable, and the cable-side connector provided at the end of the cable derived from the setting tool is provided in the body equipped with the temperature controller. It will be manually plugged into the side connector from the back of the control panel.

  Generally, since a terminal block for external wiring connection is provided on the entire back portion of a main body case in an electronic device such as a temperature controller, the main body side connector is provided facing the outer peripheral surface of the main body case. Therefore, in the case of a control panel in which a large number of electronic devices such as temperature controllers are arranged in parallel, the main body side connector of the electronic device located outside the outermost row faces a gap between adjacent electronic devices. Thus, the operator is forced to perform a troublesome operation such as picking a small cable-side connector, inserting it into the gap between the electronic devices, and inserting / removing the connector into the main body-side connector while searching with a fingertip.

  Of course, if there is a large gap between the electronic devices, the connector connection operation will be easy, but this limits the number of electronic devices that can be mounted on the control panel, and a predetermined number of electronic devices are mounted. This is not realistic because it leads to an increase in the size of the control panel. In addition, if the main unit side connector is placed facing the outer peripheral surface near the rear end of the main unit case, the connector connection operation will be somewhat easier, but this restricts the placement of the board in the main unit case and the internal wiring. From the viewpoint of the design of the electronic device.

  The present invention has been made paying attention to such a situation, and even when a plurality of electronic devices are arranged in parallel at a small interval, the cable-side connector can be easily replaced with a main body-side connector provided in the electronic device. Another object of the present invention is to provide a cable connecting jig that can be quickly connected.

  In order to achieve the above object, the present invention is configured as follows.

  That is, the present invention includes a connector holding portion for holding a cable-side connector attached to an end portion of the cable on one end side of the jig body, and an operation portion on the other end side, and the connector holding portion, A locking portion that engages with a predetermined portion of the main body case in the electronic device is provided between the operation portion, and the jig body that is engaged with the predetermined portion is swung around the locking portion as a fulcrum. The cable side connector held in the connector holding portion is connected to and disconnected from the main body side connector provided in the main body case so as to be erected in the opening on the outer surface of the main body case.

  According to the present invention, the cable side connector connected to the end of the cable derived from a setting tool such as a personal computer is held in the connector holding part of the jig body, and the jig body is brought behind the control panel, It is inserted between adjacent electronic devices, and the locking portion of the jig body is locked at a predetermined position of the main body case. Next, holding the operation part, the jig body is pivoted with the locking part as a fulcrum, the cable side connector is moved closer to the body case and inserted into the body side connector. After the connector is connected, the information input operation for changing the setting is performed, and then the jig body is removed from the main body case by performing the reverse operation to the above, and the processing of the next electronic device whose setting is to be changed is started. become.

  In a preferred embodiment of the present invention, the jig body is provided with positioning ribs that are engaged with the outer surface of the body case.

  According to this embodiment, when the locking portion of the jig body is locked at a predetermined position of the main body case, the positioning rib is engaged with the outer surface of the main body case to position the jig main body with respect to the main body case. Thus, the position of the connector holding portion when the jig body is swung can be stabilized, and the connector can be connected smoothly and accurately.

  In one embodiment of the present invention, the locking portion engages with an insulating rib of a terminal block provided on a back portion of a main body case in an electronic device.

  According to this embodiment, it is not necessary to provide a dedicated locking object in the main body case by using the insulating rib originally provided in the terminal block as the locking object of the locking part.

  In another embodiment of the present invention, a connector holding hole for penetrating and holding the cable side connector is formed in the connector holding portion, and the cable side connector is elastically formed from a narrow opening formed in the side portion of the connector holding hole. I am going to be involved.

  According to this embodiment, the cable-side connector can be easily and reliably attached to the connector holding portion of the jig body by press-fitting from the side.

  In still another embodiment of the present invention, the jig body is provided with a cable holding portion for engaging and holding the cable in a predetermined posture along the jig body.

  According to this embodiment, by holding the cable on the jig body, it is possible to prevent the cable from moving during the connector connection operation and changing the attitude of the cable-side connector.

  In one embodiment of the present invention, the cable holding portion is formed by a pair of hook-shaped protrusions having opposite cable entry directions.

  According to this embodiment, the cable can be easily engaged from a direction opposite to the pair of hook-shaped projections, but the engaged cable can be stably held in a predetermined posture without being displaced.

  As described above, by using the cable connection jig according to the present invention, the cable side connector can be easily and quickly connected to the main body side connector of the electronic device even when a plurality of electronic devices are arranged in parallel at a small interval. I was able to do that.

  And since the connector can be easily connected even in a narrow gap between electronic devices, the installation position of the main body side connector can be freely set without considering the connector connection operation, and the degree of freedom in designing the device is increased. It is also effective above.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

In the following description, the side where the connector holding portion 11 is located in the longitudinal direction of the jig body 10 is referred to as the front, and the side where the operation portion 12 is located is referred to as the rear.

  The connector holding portion 11 is provided with a connector holding hole 16 penetrating vertically. A narrow opening 17 is formed in the lateral side portion of the connector holding hole 16, and a rear wall portion 18 of the connector holding hole 16 is formed in a claw shape that can be elastically deformed in the front-rear direction. The opening 17 is expanded by the wall 18 being elastically deformed rearward.

  In addition, as shown in FIG. 7, the front and rear corners of the cable-side connector 20 connected to the end of the cable 19 are diagonally cut out to form recessed stepped portions 21 at two upper and lower positions, The planar shape of the connector holding hole 16 is matched with the connector cross-sectional shape in the recessed step 21. Further, raised portions 22 and 23 are formed on the front and back of the hole edge in the connector holding hole 16, and the thickness of the connector holding hole 16 in the portion where the raised portions 22 and 23 are formed is the vertical width of the recessed step portion 21. The cable-side connector 20 is orthogonal to the jig main body 10 because a part of the hole edge of the connector holding hole 16 is engaged with the upper recessed step portion 21 at the portion where the raised portions 22 and 23 are formed. It is penetrated through the connector holding hole 16 in a vertically oriented manner, and is stably held in a state where it is prevented from moving up and down.

  As another embodiment of the present invention, as shown in FIG. 10, a ridge 50 is added to the hole edge of the connector holding hole 16 on the end side of the opening 17 on the back surface of the connector holding part 11 to provide a cable. The connector 20 may be held more stably by preventing the connector 20 from moving obliquely.

  As shown in FIG. 4A, protrusions 24 are formed at a plurality of positions on the front and rear surfaces of the operation unit 12 to prevent slipping of fingers during operation.

  The locking portion 13 is provided with a locking hole 25 that opens forward, and a support protrusion 26 is provided immediately in front of the locking hole 25.

Ribs 28 are provided so as to project rearward, and the locking holes 25 can be externally engaged and locked to the lowermost insulating ribs 28 from the rear. More specifically, a narrow protrusion 28 a is continuously provided at the rear end side of the insulating rib 28, and the opening width of the locking hole 25 is slightly larger than the protrusion 28 a and is larger than the width of the insulating rib 28. It is set small. Therefore, when the locking hole 25 is externally fitted to the protrusion 28 a, the opening end of the locking portion 25 comes into contact with and supports the rear end side of the insulating rib 28.

  The positioning ribs 14 shown in FIG. 4A and FIG. 7 are projected on the left end side of the jig body 10 in the shape of a vertical wall having an appropriate front-rear length, and the locking portion 25 is insulated as described above. The jig main body 10 can be positioned in the left-right direction with respect to the main body case 2 by bringing the positioning rib 14 into contact with the left side surface of the main body case 10 while being engaged with the ribs 28. .

  As shown in FIG. 4 (b), the cable holding portion 15 is configured by projecting a pair of front and rear hook-shaped protrusions 29 for engaging the cable 19 from the lateral direction. Engagement directions are opposite to each other. In addition, as shown in FIG. 6, an inclined raised portion 29 a is formed on the upper surface of the free end portion of the hook-shaped protrusion 29 so as to provide resistance to the cable 19 being pulled out. The cable 19 engaged with the projection 29 is stably held in a front-rear orientation along the jig body 10.
