Abstract
The invention discloses a crimp-type coaxial connector which comprises: a crimping needle, a shielding shell, an insulator and a crimping suite. The crimping needle is arranged in the insulator. A shield extends a crimping pipe out of the shielding shell. An inner diameter of the crimping pipe is larger than an external diameter of the crimping suite. The crimping suite is sleeved on an oversheath of an incoming end of an external cable. The crimping suite and the oversheath of a coaxial cable are inserted into the crimping pipe. A shielding net is overturned on the crimping suite. At this moment, the shielding net is between an inner wall of the crimping pipe and an outer wall of the crimping suite. Through pressing the crimping pipe, the crimping pipe presses the crimping suite and the shielding net of the cable. And then the crimping suite is pressed so that the coaxial cable sheath is pressed tightly. The connector of the invention can be used to guarantee a tight connection of the cable under the condition of strong vibration impact and possesses a strong tensile ability.

Purpose of the present invention is achieved through the following technical solutions: a kind of compression joint type coaxial cable crimp connector, comprise the crimping pin, shield shell, insulator, pressure welding case, described crimping pin is positioned at insulator, described shield stretches out an aluminium hydraulic pressed connecting pipe outside shield shell, the internal diameter of described aluminium hydraulic pressed connecting pipe is greater than the external diameter of pressure welding case, described pressure welding case is enclosed within on the oversheath of incoming end of external electric cable, pressure welding case inserts in the aluminium hydraulic pressed connecting pipe together with the oversheath of coaxial wire, gauze screen is turned on pressure welding case, this moment, gauze screen was between the outer wall of the inwall of aluminium hydraulic pressed connecting pipe and pressure welding case, by compressing aluminium hydraulic pressed connecting pipe, make aluminium hydraulic pressed connecting pipe compress the gauze screen of pressure welding case and cable, compress pressure welding case again, the coaxial cable sheath is compressed.
Thus, can compress whole coaxial cable simultaneously, increase thrust, after the coaxial cable sheath is compressed together, improve tensile strength after the crimping by aluminium hydraulic pressed connecting pipe and pressure welding case.
On the basis of the above, compression joint type coaxial cable connector of the present invention also can be done following improvement:
The difference of the internal diameter of described aluminium hydraulic pressed connecting pipe and the external diameter of pressure welding case in scope, select all at 0.5mm～2mm can, be used to adapt to gauze screen density, thereby can increase or reduce the gap between aluminium hydraulic pressed connecting pipe and the gauze screen as required, regulate thrust.
The outer wall of described aluminium hydraulic pressed connecting pipe can increase along the radially equally distributed annulus of aluminium hydraulic pressed connecting pipe, regulates the external diameter of aluminium hydraulic pressed connecting pipe by annulus thickness, to adapt to standard Crimping Pliers port sizes.
A kind of as above-mentioned method of attachment of compression joint type coaxial cable connector may further comprise the steps:
(1) with the oversheath excision of coaxial wire pressure connection terminal, exposes gauze screen and coaxial cable inner core sheath;
(2) pressure welding case is enclosed within on the oversheath that the coaxial wire pressure connection terminal do not excise, the gauze screen upset that will expose also evenly is pasted on the outer wall of pressure welding case;
(3) the cable inner core is exposed in the cable inner core sheath excision that will expose;
(4) coaxial cable inner core wire is pressed in the crimping pin;
(5) pressure welding case and gauze screen are conversely inserted in the aluminium hydraulic pressed connecting pipe, simultaneously the cable inner core is inserted in the insulator;
(6) select suitable Press Plier port to compress aluminium hydraulic pressed connecting pipe, coaxial cable shield net and pressure welding case are compressed.
(7) select suitable Press Plier port to compress pressure welding case, coaxial cable sheath and pressure welding case are compressed.
Compared with prior art, this invention has the following advantages:
1, adapt under the environment that judder is impacted and use, crimp strength height, resistance to tension are very good;
2, the outer wall of aluminium hydraulic pressed connecting pipe can increase along the equally distributed ring-type annulus of aluminium hydraulic pressed connecting pipe normal direction, regulates the external diameter of aluminium hydraulic pressed connecting pipe by annulus thickness, can come the not coaxial cable of collinear warp of crimping by the choice criteria Crimping Pliers, avoids the custom-made crimping tool.
