Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0030] An 8-core circular 1394 signal contact piece, including a dielectric body assembly 1, the entire body of the dielectric body assembly 1 is socketed inside the outer sleeve 7; the dielectric body assembly 1 and the outer sleeve 7 The space is fixed by a locking piece 8; the outer sleeve 7 is used to protect the medium body assembly 1 from the outside, and the locking piece 8 is arranged to prevent the medium body assembly 1 from rotating in the outer sleeve 7;
[0031] The dielectric body fitting 1 includes an upper pressing part 2, a conductor fixing part 3, an inner conductor 4, a lower pressing part 5 and a cross s...

An 8-core circular 1394 signal contact, including the dielectric body assembly including an upper pressing member, a conductor fixing member, an inner conductor, a lower pressing member and a cross shielding member, and the inner conductor is inserted in an annular array. On the conductor fixing piece, the bottom of the inner conductor is externally clamped with a lower pressing piece, the top of the inner conductor is externally clamped with the upper pressing piece, and the top end of the conductor fixing piece protrudes into the place. Inside the upper pressing piece, the bottom end of the conductor fixing piece protrudes from the lower pressing piece, and the cross shielding piece is inserted into the inner center of the conductor fixing piece; A second partition is arranged in the conductor placement groove, which can separate 8 inner conductor installation areas to realize 8-core configuration;
Description
technical field [0001] The invention belongs to the technical field of communication equipment, in particular to an 8-core circular 1394 signal contact. Background technique [0002] The interface of the 1394 card is called the IEEE1394 interface or the Firewire interface. The 1394 card has two interfaces; the IEEE1394 interface is a serial standard developed by Apple; like USB, IEEE1394 also supports hot plugging of peripherals, which can provide power for peripherals , saves the power supply that comes with the peripherals, can connect multiple different devices, and supports synchronous data transmission; [0003] During the use of circular 1394 signal contacts, the requirements for its external dimensions are becoming more and more miniaturized, and the requirements for the quantity and quality of signals have increased; at present, most of the circular 1394 signal contacts are 2 cores and 4 cores , unable to meet the needs of high-speed communication.
