Description

  The present invention relates to a terminal position specifying device for a connection terminal board provided in an intermediate wiring board.

  As shown in FIG. 8, an intermediate distribution board 710 (IDF: Intermediate Distribution Frame) is installed for each unit such as each floor in an apartment house, an office building, etc., and a transmission device (for example, a telephone 720). Relay between main wiring boards such as 700. A plurality of connection terminal boards 800 are arranged on the intermediate wiring board 710 (see, for example, Patent Document 1).

  Each connection terminal plate 800 includes a rectangular substrate 810 and a plurality of terminals 815 arranged in a matrix. The multi-core cable 721 extending from the plurality of telephones 720 is electrically connected to the plurality of terminals 815 arranged continuously in the horizontal direction among the plurality of terminals 815 arranged in the matrix in a one-to-one relationship. Similarly, the multi-core cable 701 extending from the main wiring board is also electrically connected to the plurality of terminals 815 arranged continuously in the lateral direction on a one-to-one basis.

  The inspection of the wiring connection of the connection terminal board 800 is performed by electrically connecting the contact portion of the inspection apparatus 900 to a specific terminal 815. At this time, the terminal 815 is identified by relying on an index formed of a numeric label symbol 820 written in the horizontal direction and an alphabet label symbol 830 written in the vertical direction formed around the matrix.

  However, as shown in FIG. 9, since the distance L between two terminals 815 adjacent to each other is as narrow as 8 to 9 mm, for example, the inspector specifies the position of the terminal 815a to be inspected as the distance from the index increases. Hard to do. Specifically, the inspector cannot easily determine that the position of the terminal 815 with the symbol a is “14J”.

  In order to clarify the terminal 815a to be inspected in advance, the inspector, for example, attaches the terminal 815b in the lateral direction of the terminal 815a to be inspected and the tip of the terminal 815 adjacent thereto to adhesive and insulating. Cover with a vinyl tape 750 having

  However, it is difficult to specify the terminal 815b adjacent to the terminal 815a to be inspected as the distance from the index increases.

In addition, since the area where the tip of the terminal 815 is in contact with the vinyl tape 750 is very small, the vinyl tape 750 may be peeled off from the tip of the terminal 815 during the inspection.

  1 to 3, the terminal position specifying device 10 is detachably assembled to a connection terminal plate 800 having a rectangular substrate 810 and a plurality of terminals 815 arranged in a matrix.

  The terminal position specifying device 10 includes a base portion 20, an arm portion 30, and a movable portion 40 that hides one or more specific terminals 815 b among the plurality of terminals 815.

  The base portion 20 has a pair of base positioning portions 21 and 21 that are removably assembled to the frame 710a of the intermediate wiring board in the vicinity of the periphery of the substrate 810. The pair of base positioning portions 21, 21 are formed in a rectangular parallelepiped shape extending in the vertical direction Y perpendicular to the horizontal direction X, and are disposed on both sides of the substrate 810. In the present embodiment, the base portion 20 has a pair of base positioning portions 21, 21, but may have only one base positioning portion 21. In the terminal position specifying device 10, the horizontal direction and the vertical method correspond to the first direction and the second direction, respectively.

  On the frame 710a side of the base positioning portion 21, there is a permanent magnet 23 that can stick to the frame 710a. The base positioning portion 21 is attached to the frame 710a so as to maintain a predetermined positional relationship with respect to the substrate 810 as will be described later.

  The base portion 20 has a support portion 22 that supports the arm portion 30 so as to be movable above the terminals 815. The support portion 22 is formed with a slit 24 into which one end of the arm portion 30 is inserted. The arm portion 30 is inserted into the slit 24 so that the arm portion 30 translates in the vertical direction Y while forming a slight gap between the arm portion 30 and the tip of the terminal 815. In other words, the arm portion 30 is held by the base portion 20 so as to be slidable in the vertical direction Y and intersect the base positioning portion 21 at a right angle.

  On the surface 20a of the base portion 20, alphabetic label symbols 25 are attached at intervals equal to the distance M between two terminals 815 adjacent in the vertical direction Y. Thereby, the inspector can grasp the symbols 25 and 830 for the terminal 815 where the arm portion 30 is located by looking in the direction Z (see FIG. 2) perpendicular to the substrate 810.

  In addition, a number may be attached to the surface 20a of the base part 20 instead of a scale, and a scale and a number may be attached. Thereby, it is possible to easily grasp where the arm part 30 is located with respect to the substrate 810.

  As shown in FIG. 3, the arm part 30 extends in the horizontal direction X parallel to one side of the matrix. The terminal position specifying device 10 further includes a movable unit 40 that is guided by the arm unit 30 and hides one or more specific terminals 815b among the plurality of terminals 815.

  An insulator 37 such as rubber is attached to the side surface 30b of the arm portion 30 on the side where the terminal 815 is disposed. Thereby, even if the arm part 30 approaches the tip of the terminal 815, the insulator 37 is disposed between the arm part 30 and the tip of the terminal 815, so that the terminal 815 and the arm part 30 are electrically connected.

  The movable part 40 includes three movable pieces 41, 42, 43. The arm portion 30 has grooves A, B, and C that allow the movable pieces 41, 42, and 43 to slide in the horizontal direction X. The grooves A, B, and C extend in parallel with each other in the horizontal direction X so as to align with the direction Z in which the terminals 815 extend.

  The movable pieces 41, 42, 43 are rectangular plate-like members. The length of the movable pieces 41, 42, 43 in the horizontal direction X has the same length as an integral multiple of the distance L between adjacent terminals. Specifically, the movable piece 41 has the same length as three times the distance L between the terminals (see FIG. 1). The movable piece 42 has a length that is one time the distance L between the terminals, that is, the same length as the distance L between the terminals. The movable piece 43 has the same length as twice the distance L between the terminals. Any of the movable pieces 41, 42, 43 may be provided with a known expansion / contraction mechanism. In this case, the movable pieces 41, 42, 43 and the movable part 40 function as an extendable movable part.

The grooves A, B, and C extend in parallel with each other in the vertical direction Y so as to align with the direction Z in which the terminal 815 extends. The grooves A, B, and C are formed on the left side of the arm portion 30B, but may be formed on the right side.

  The movable pieces 41B, 42B, and 43B are rectangular plate-like members. The length in the vertical direction Y of the movable pieces 41B, 42B, and 43B has the same length as the integral multiple of the distance M between adjacent terminals. Any of the movable pieces 41B, 42B, and 43B may be provided with a known expansion / contraction mechanism. In this case, the movable pieces 41B, 42B, 43B and thus the movable portion 40B function as an extendable movable portion.
