Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a connector drawing tool used during experiments, inspections, etc. of electronic equipment.

(Prior art) For example, various communication systems, various measurement systems,
2. Description of the Related Art In electronic devices such as various computer systems, a structure is known in which the entire system is constructed by connecting various device units to a main body of the device using connectors. In such systems, the connection between the equipment unit and the main body of the apparatus is usually made at the back of a cabinet constituting the main body of the apparatus, and the equipment unit is housed in the cabinet. Therefore, when conducting experiments or inspections on the inside of the equipment unit while it is connected to the equipment main body,
It is necessary to pull out the connector installed at the back of the cabinet to the outside of the cabinet, and as a tool for this purpose, attach a pair of male and female connectors to both ends of a printed board whose length is longer than the depth of the cabinet, and connect the corresponding contacts of the pair of connectors. A device in which the pins are electrically connected by a conductive pattern is used. That is, by attaching the tool to the apparatus main body instead of the equipment unit to be inspected, it is equivalent to pulling out the connector at the back of the cabinet to the outside of the cabinet.

By the way, when there are many types of equipment units to be attached to the main body of the apparatus, the position of the connector attached to the back side of the cabinet is not necessarily the same for each equipment unit. That is, for example, in a system in which the position of the connector is made different for each type of equipment unit in order to prevent wrong installation of different types of equipment units, as proposed by the present applicant in another patent application, the same structure may be used. cannot use the connector extraction tool. In such cases, conventionally, connector pull-out tools have been made from printed boards having separate conductive patterns for each equipment unit.

(Problems to be Solved by the Invention) According to the above-mentioned conventional technology, the printed boards used for the connector pull-out tool need to have different conductive patterns depending on the equipment unit, and the types of printed boards have increased. Not only are the drawer tools expensive, but each time a new system is developed, a connector drawer tool must be created to suit that system.

The object of the present invention is to obtain a structure of a versatile connector drawing tool that can solve these problems.

(Means for Solving the Problems) For the above purpose, the present invention provides contact pin terminal connection patterns at two ends of a printed circuit board with the contact pin spacing of the connector being equal to or greater than the number of the contact pins. The corresponding contact pin terminal connection patterns at the ends of the two locations are electrically connected to each other by conductive patterns, and at the ends of the two locations, each of the pair of female and male connectors is connected with the contact pin spacing between them. The connector can be connected and fixed at any arbitrary position as a positioning unit, and the connector of the connector pull-out tool can be fixed in accordance with the position of the connector on the main body of the device.

(Configuration of Embodiment) FIGS. 1, 2, and 3 are a front view, a left side view, and a right side view, respectively, of a connector drawing tool according to an example of the present invention. Note that the mounting positions of the connectors shown in the drawings are one example.

In Figures 1 to 3, 1 is a printed board, 2
is a male connector, and 3 is a female connector.

A large number of connector contact pin connection terminal wiring holes (hereinafter referred to as wiring holes) 101 are provided at both ends of the printed board 1 at equal intervals, and the number is equal to the contact pins 201 and 301 of the connectors 2 and 3. is greater than or equal to the number of

On the back side of the printed board (the side on which the connectors 2 and 3 are not fixed), there is a connection pattern 102 for electrically connecting the contact pin terminals 202 and 302 of the connectors 2 and 3 around the wiring hole 101, and a connection pattern 102 on both ends. A conductive pattern 103 is formed that electrically connects corresponding connection patterns 102 in the section.

The set interval a of the connection pattern 102 (wiring hole 101) is between the contact pin terminals 2 of the connectors 2 and 3.
It is set equal to the interval b of 2,203. Note that the interval between the contact pins 201 of the connectors 2 and 3 is normally set to be the same as the interval b between the contact pin terminals 202 and 302.

(Operation of the embodiment) With the printed board 1 configured as described above, the male connector 2 and the female connector 3 can be connected to the contact pin terminals within the range where the wiring hole 101 (connection pattern 102) is provided. The interval b of 202 can be used as a unit of positioning and can be fixed at an arbitrary position. Therefore, if the printed board 1 with the above structure is prepared, the desired connector pull-out tool can be created by simply wiring and fixing the male connector 2 and female connector 3 to the printed board 1 in accordance with the position of the connector on the main body of the device. can do. Incidentally, within one connector drawing tool, the male connector 2 and the female connector 3 are usually fixed at the same location on both ends of the printed board 1.

(Effects of the invention) As described above, in this invention, the number of wiring patterns is provided at both ends of the printed circuit board, with the spacing between the contact pins of the connector being equal to or greater than the number of contact pins of the connector. In addition, by being able to freely set the position of the connector, it is possible to create many types of connector pull-out tools using one type of printed board, making it possible to realize extremely versatile connector pull-out tools, and the present invention has remarkable effects. It is something.
