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 facilitate the release of a lock and improve mounting efficiency by having a built-in lock release mechanism in a connector. CONSTITUTION: The lock engaging window 7 of a receptacle side connector housing 1a and the lock engaging button 3 of a plug side connector cover 2 are engaged with each other, and then, the lock release slant face 8 of the tip 4a of a slide member 4 touches the slant face 3a of a lock engaging dowel 3. When an extracting tab 5 is pulled in the direction of an arrow sign P by fingers or the like, the lock release slant 8 of the slide member 4 coupled therewith pushes down the slant face 3a of the lock engaging dowel 3 of the resilient plug side connector cover 2 so that the lock engaging dowel 3 is made to escape from the lock engaging window 7 toward inside to release lock. When the extracting tab 5 is continuously pulled in the direction of the arrow sign P after the release of the lock, a plug side connector is finally uncoupled from a receptacle side connector.

摘要： PURPOSE:To provide a desired contact force between the internal circumferencial plane of the through hole of MDF matrix board and a contact pin even if the internal stress of a contact spring is made smaller by improving the shape of the contact spring. CONSTITUTION:The main body of a contact pin is made of resin and comprises a conical tip end 1, a small-diameter shaft 2, and a large-diameter holding part 3. A contact spring B, which is a little shorter than the shaft 2, is provided along the circumference of the shaft 2 coaxially, and comprises a cylindrical spring device having a cut opening 4 on the side in the axial direction. The contact spring B has three protrusions 11, 11', and 12 extending in the axial direction at the positions positionally relating to the cut opening 4. This constitution can make the internal of the contact spring half compared with the conventional one, use materials of so much less elastic limit, and lessen the height and thickness so as to realize cost reduction.

摘要： PURPOSE:To provide a coaxial pin connector easy to build with a small number of part items, relating to a structure for the coaxial type multiterminal pin connector whereby a high speed transmission signal handled in a communication equipment or exchanger and the like can be efficiently transmitted. CONSTITUTION:A through hole 2 inserted through a base of a backboard 1 is provided in a position corresponding to each pin 4. The through hole corresponding to a signal transmitting pin 4a is formed so as to provide a small internal diameter press-fitted to a side surface of the signal transmitting pin 4a in a region of the first base 5 but a large internal diameter not coming into contact with the side surface of the signal transmitting pin 4a in a region of the second base 6. The through hole corresponding to an earthing pin 4b is formed so as to provide a small internal diameter press-fitted to a side surface of the earthing pin 4b through the regions of the first/second bases 5, 6, to electrically connect to each other the external conductors 10, 10' in the region of the second base 6 of the through hole corresponding to both pins.

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.
