摘要： PURPOSE:To accomplish the consistency and standardization of the external appearance by providing support bars opposing to each other in the upper and lower front edge parts of a shelf, providing on one end an insertion flange and a removal flange for inserting and removing a plug-in printed board in a face-to-face relationship and engagement with the support bars, and providing on the other end levers pivotally supported for swinging. CONSTITUTION:Support bars 3 are provided in the upper and lower front edges of a shelf 2 which allows a plurality of plug-in printed boards 1 to perform the mutual circuit connections. And on the front upper part and front lower part of the plug-in printed boards 1, an insertion flange 5 and a removal flange 6 for inserting and removing the plug-in printed board 1 are provided on one end in a face-to-face relationship and engagement with the support bars 3, and on the other end, levers 4 are provided which are pivotally supported for swinging. Also, a cutout 7 of a width W is provided in the support bars 3 correspondingly to the position in which the plug-in printed board 1 is mounted, and it is made to satisfy W1>W>W2 if the engagement widths of the lever 4 with the insertion flange 5 and of the removal flange 6 with the support bar 3 are W1 and W2. With this, the same standard item is used as levers 4 of the plug-in printed boards 1, so there will be no discrimination in the external appearance.

摘要： PURPOSE:To bind insulating wires safely by bending a belt-formed thin plate into U-shape, inserting plural insulating wires inside the U-shape, and imposing a pressure to the wires from the opening side. CONSTITUTION:In a calking jig 3 which consists of an upper pattern 3a and the lower pattern 3b, a pressing rod 3a-1 buffed with a compressive spring 3a-2 inside the upper pattern 3a is arranged being hung at the center position of calking movable in the direction of the calking. By using a calking jig 3 which has recesses 3c in the form to calk a binding ring 1 in a ring form by combining the upper and the lower patterns 3a and 3b, and the binding ring 1, plural insulating wires are bound into a single line. Consequently, the pressing rod 3a-1 which is buffed by the compressive spring 3a-2 can impose a constant pressure to the insulating wires 2 in the process of calking until the U-shaped opening is closed, and the insulating wires 2 are prevented from pinching partially or swelling out.

摘要： PROBLEM TO BE SOLVED: To simplify structure, to allow fitting and removing by weak operating physical force, and to prevent damage caused by exposure of a locking spring member. SOLUTION: When a plug 1 is inserted into a receptacle 11 under a condition of (a) before engagement, a state is brought into a condition of (b), and respective outside protrusions 4C of plural plate spring pieces 4B of an inside contact 4 contact with an inner circumferential face of an outside contact 14. Since an inner circumferential face 6C of a coupling member 6 pushes the second outside protrusions 5E of plural plate spring pieces 5B of an outside contact 5 when the member 6 is slided to a right direction, respective inside protrusions 5C are fitted to a circular groove 14A of the contact 14. Since the face 6C approaches to the respective first outside protrusions 5D to face each other so as to bring a condition of (c), the respective protrusions 5C are prevented from being escaped out of the circular groove 14A, that is, locked.

摘要： PURPOSE:To prevent a cable-provided contactor from coming off from a housing by inserting a cable point end stopped to a rectangular slit of a housing, fixing a cut raised tongue piece to the cable point end, and forming a width of the tongue piece so as to widen in the point end part and narrow toward the root. CONSTITUTION:An external contact 22 comprises arm open barrel part 22a of large diameter, intermediate part 22b and a point end part 22c of small diameter. Four calking pawls 24 are provided in the barrel part 22a, and by calking the pawls 24 fixed to an external conductor 6a and a cover 6d of a coaxial cable 6, the external contact 22 is mounted on a point end of the coaxial cable 6. A pair of tongue pieces 26, formed by cutting raised, are integrally provided in the intermediate part 22b. The tongue piece 26 is formed so as to widen in the point end part and gradually narrow toward the root part. An insulator 32 is inserted into the intermediate part 22b and the point end part 22c, and a center contact 30, calked by a pawl 30a to a center conductor 6b of the cable 6, is inserted into this insulator 32. Since, the point end part of the tongue piece 26 is widened, when the contact 22 is inserted into the housing, coming off from the housing is prevented.

摘要： PURPOSE:To enable the efficient supply of frame earths in the packaging and the electrical characteristics by providing structural members also acting as earth bars in the upper and lower front edge parts of a shelf so that they are opposed to each other, and making insertion and removal means and locking means electrically conductive to the structural members of the shelf and the surface plate. CONSTITUTION:Structural members 7 also acting as earth bars are provided in the upper and lower front edge parts of a shelf 5 so that they are opposed to each other. A printed wiring board 2 is provide with a plug-in connector 3 in the rear edge thereof to allow all the internal frame earths to collectively be connected to a metallic surface plate 4 provided covering the front part, and provided with insertion and removal means and locking means to the shelf 5 in the part, constituting a circuit unit 1. Here, the frame earth connection of the shelf 5 and the circuit unit 1 is made so that they are made electrically conductive to the structural members 7 of the shelf 5 and the surface plate 4. With this, each frame earth wiring becomes short, thereby enabling the efficient supply of the frame earths.
