Patent number: 6618945Abstract: A tool for stripping a microcoaxial cable having an outside diameter of four millimeters or less. The tool is operable for precisely stripping the jacket, shield and dielectric layers of the microcoaxial cable under field conditions. The tool comprises a fixed gripping portion that holds and supports the cable both proximal and distal to the portion to be stripped. A blade portion rotatably mounted to the fixed gripping portion has a double action. When the blade portion is depressed, a plurality of blades mounted thereon cuts into the microcoaxial cable to precise and adjustable depths. A 360° rotation of the blade portion relative to the fixed gripping portion cleanly severs the respective layers of the cable. The respective severed layers of the cable are removed by hand to expose the underlying layer and the central conductor thereby providing a stripped portion of microcoaxial cable to which a microcoaxial cable connector can be attached.Type: GrantFiled: December 19, 2001Date of Patent: September 16, 2003Assignee: Holland Electronics, LLCInventors: Michael Holland, Shen Chia Wong

Patent number: 5975949Abstract: A coaxial cable end connector for connecting a cable to a terminal has inner and outer spaced concentric sleeves, the outer sleeve provided with sealing rings which are formed out of the thickness of the outer sleeve along a crimping zone of the sleeve to minimize the crimping force required to crimp the outer sleeve by inward radial deformation into sealing engagement with the cable. Preferably, the wall thickness of at least a portion of the outer sleeve is reduced in order to further reduce the crimping force required to deform the sleeve into sealing engagement with the cable. In certain applications, an external annular seal is interposed between confronting surface portions of one of the inner and outer sleeves and a coupling member which makes up onto the terminal in sealing against moisture infiltration.Type: GrantFiled: December 18, 1997Date of Patent: November 2, 1999Assignee: Randall A.

Patent number: 5863226Abstract: A connector for coaxial cable, including a main body formed with an inner passage in which a pair of insulative sleeves are fitted. Each insulative sleeve is disposed with a small diameter section. A tubular contact member is fitted between the small diameter sections of the two insulative sleeves. The contact member is made of a sheet material by means of curling. Two ends of the contact member are not adjoined together so as to define a narrow slit. An opposite side of the slit is also formed with two slits which are not adjacent to each other so that when a core with 1.2 to 1.3 mm diameter is inserted into the contact member, the contact member is stretched open to achieve greater resilience.Type: GrantFiled: September 12, 1996Date of Patent: January 26, 1999Inventors: Cheng Sun Lan, Shen-Chia Wong

Patent number: 5667409Abstract: An improved structure for the connector of a coaxial cable ensures that there are multiple contact points between the contact component and the central wire of the coaxial cable. The connector has holes on the top and bottom of the two ends of the contact component. The material of the holes is punched inward but is not removed from the tube forming the contact component such that a pair of inclined planes extend toward the interior of each end of the tube. One pair of insulation components which slip on the inside of the connector body join with one end of the contact component to fix and to support the contact component in order to increase the quality of transmission. The connector can be used in a specific range of central wire for cable that allows larger current flows, therefore being suitable for use in a combination of TV and telephone as well as with the current cable TV system.Type: GrantFiled: December 28, 1995Date of Patent: September 16, 1997Inventors: Shen-Chia Wong, Cheng Sun Lan
