Separate Spring Means Moves Rigid Nonresilent Clamping Part Into Securing Condition Patents (Class 439/819)
  • Patent number: 10784623
    Abstract: A connector for connecting together rigid structures. The connector includes a stack of coupling contacts pivotably disposed within a housing. Each coupling contact is generally H-shaped and defines opposing first and second spaces. The first and second spaces are aligned to form first and second receiving grooves in the stack, respectively. The connector may also include one or more mounting contacts partially disposed within the housing. Each mounting contact has one or more fastening structures joined to a bar section. The fastening structures are adapted for securement to the substrate and the bar section is disposed in the second receiving groove of the stack of coupling contacts.

  • Patent number: 9455515
    Abstract: A distance between first contact portions is set smaller than a thickness of a first connection object in the state where neither of the first connection object and a second connection object is inserted into a contact. A distance between second contact portions is set greater than a thickness of the second connection object in the state where neither of the first connection object and the second connection object is inserted into the contact. When the first connection object is inserted between the first contact portions, a pair of conductive portions are relatively moved to shorten the distance between the second contact portions so that the second connection object is held between the second contact portions.

    Abstract: A low voltage drop, high current electrical connector which can be releasably mated with associated contacts is disclosed. The connector makes use of elongate contact arms cantilevered in a housing. Each contact arm is made up of at least two beams one of which has relatively high electrical conductivity but relatively poor mechanical spring characteristics. The other has relatively low electrical conductivity but relatively good mechanical spring characteristics. In this way the mechanical and electrical characteristics such as contact force and conductivity may be controlled, balanced and optimized. As one possibility there could be a single spring steel beam backing a stack of sheets of high conductivity copper. As another possibility, there could be sheets of high conductivity copper alternating in a stack with sheets of copper spring which is about half as conductive as pure copper. Instead of a cantilevered spring a coil spring located at the contact surface could be used.

    Abstract: A socket is constructed in such a way that six pieces of segments which are made of electric conductive bar and having a regular hexagonal cross section are assembled by a centripetal force of a spring band to provide a regular hexagonal plug inserting hole in its center, and the six pieces of the segments make an independent operation without restricting other segments mutually and having the contact pressure and make a positive corresponding operation against the center offset and the error of the inserting angle of the plug when the plug is inserted and each segment applies the contact pressure simultaneously against the plug to maintain the complete contact with the plug.

  • Patent number: 4946407
    Abstract: A high current carrying connector plug and receptacle are disclosed. The plug comprises a body of electrical insulating material with plurality of shaped passages extending therethrough, electrical conductors having a flat blade contact portion, a stop means and a hollowed cylindrical portion for receiving and securing a current carrying electrical cable. The passages include stop engaging means. A retainer means engages the flat bladed portion preventing axial movement of the conductors in the plug body.The receptacle comprises a body of electrical insulating material having shaped passages therethrough, electrically conductive conductor contact engaging assemblies in each passage at the front face of the body. The contact assemblies comprise movable jaws having a front contact engaging portion and a rear coupler engaging portion and a spring retainer means converging at least one pair of jaws.

  • Patent number: 4897043
    Abstract: A resilient contact pin for contacting electrical or electronic items to be tested, such as conductor plates, printed circuit boards or the like, the resilient contact pin being electrically conductive and intended for mounting on a testing arrangement, includes a straight cylindrical member including a metallic tube constituted by a punched and bent sheetmetal part. A contact member includes a piston accommodated in the metallic tube for axial sliding and a frontward end portion projecting out of the metallic tube and serving for contacting the item to be tested. A spring is accommodated in the metallic tube and urged the contact member in a frontward direction relative to the metallic tube. There is further provided at least one lug constituted by an integral region of a circumferential wall of the metallic tube and extending into the interior of the metallic tube to constitute an abutment which limits the extent of the frontward movement of the piston of the contact member.

  • Patent number: 4743201
    Abstract: A moveable contact plunger assembly for interconnection of electrical wires between adjacent railway cars. The assembly has a plunger with a shoulder which fits in abutment with a mating shoulder in an aperture of a dielectric connector block. A follower element is arranged for electrical contact with the plunger. A spring is arranged to allow axial deflection of the plunger relative to the follower element and of the follower element relative to the dielectric block shoulder. Electrical continuity between the plunger and the follower element is obtained by means of a wire which is crimped to the follower and to the plunger. A guide pin mounted on the follower element and a guide slot on a spring barrel portion of the plunger coact with the spring so as to allow axial travel of the follower and of the plunger as well as a rotating motion of the plunger during its axial travel.
