Coaxial connector

Technical field

The present invention relates to coaxial connector, relate in particular to having of in the communications industry and electronic equipment, using and insert the coaxial connector that self-locking connects and can separate fast.

Background technology

Coaxial connector is a kind of of microwave component, is the electromechanical compo that is used for connecting various microwave circuits.Can be used for the I/O mouth of microwave apparatus equipment, the connection between the various radio-frequency module and the connection between transmitter and the antenna etc.Coaxial connector must satisfy the impedance matching requirement, must be able to satisfy the electric of transmission system and mechanical performance requirement.Coaxial connector is made up of plug and socket two parts, and generally, the active coupling part that has locking device is called plug, and passive coupling part is called socket.Traditional connected mode of coaxial connector has: be threaded, bayonet socket connection, plug-in type connection etc.But problems such as all there is vibrating failure in these connected modes, transmission characteristic is discontinuous, installing space is big, attended operation complicacy.Therefore occur some at present and had the connector of connection of inserting and auto-lock function; Realize through spring retaining mechanism and tripper; But operating difficulties when existing release to separate, complex manufacturing, the shortcoming that production cost is high all can not satisfy the requirement of electrical equipment and mechanical properties.

Summary of the invention

The technical problem that the present invention will solve is the deficiency that overcomes prior art, provide a kind of safe and reliable, have good radiofrequency characteristics with Rational structure, realization is easy, production technology is simple, lower-costly be used for the radio frequency (RF) coaxial connector that microwave is connected.

The technical scheme that the present invention adopts is: comprise plug and socket; Plug comprises the plug outer conductor; Socket comprises the socket outer conductor; Be connected with spring retaining mechanism, annulus reconciliation lock barrel between the plug and socket, the spring retaining mechanism is made up of the arc thin-wall spring retaining mechanism that 6-12 band inclined-plane hook ends the branch tooth, and each band inclined-plane hook only divides arc thin-wall spring retaining mechanism of tooth to have an arc thin-wall spring; The afterbody extension assembling matrix of arc thin-wall spring, top are extended hook and are ended the branch tooth, and hook only divides tooth to be made up of continuously contact inclined-plane, lead-in chamfered and two arc crotch; Assembled base is external to be enclosed within on the plug outer conductor, and annulus is enclosed within outward in the tight mechanism of springlock, and the release bush outer sleeve is coated at the plug outer conductor and the socket outer conductor of part simultaneously in spring retaining mechanism and annulus; Separate between lock barrel and plug outer conductor, the annulus external diameter and have certain clearance; The afterbody of annulus is provided with and is stuck in the projection in the respective grooves on the release sleeve lining; Separate in the top of lock barrel hook-shaped wedgewise and separate lock ring, wedge shape is separated lock ring corresponding to said lead-in chamfered; Wedge shape is separated between inner top surface position and said pair of arc crotch of lock ring has certain distance; A supporting projections is set on socket outer conductor outer surface, and said contact inclined-plane is contacted with on this supporting projections respective side.

[0006]The present invention conciliates connection that lock barrel realizes plug and socket and separates through the spring retaining mechanism, under shock conditions, still can reliably connect, and easy and simple to handle, transmission characteristic is good, satisfies each item requirement of electrical equipment and mechanical performance.

Embodiment

Shown in accompanying drawing 1, the present invention includes plug 1 and socket 2, connect spring retaining mechanism 6, annulus 7 reconciliation lock barrels 8 between plug 1 and the socket 2.Socket 2 comprises socket outer conductor 9, and plug 1 comprises inner wire 3, insulator 4 and plug outer conductor 5, the coaxial installation of three, and insulator 4 is installed between inner wire 3 and the plug outer conductor 5.

As shown in Figure 2, spring retaining mechanism 6 is made up of the arc thin-wall spring retaining mechanism that 6-12 band inclined-plane hook ends the branch tooth, adopts the beryllium-bronze elastomeric material punch forming of complete soft attitude.The arc thin-wall spring retaining mechanism that each band inclined-plane hook ends the branch tooth has an arc thin-wall spring 64, and the afterbody of arc thin-wall spring 64 extends assembling matrix 67, and the top of arc thin-wall spring 64 is extended hook and ended branch tooth 62.Hook ends the structure of dividing tooth 62 to be made up of contact inclined-plane 61, lead-in chamfered 66 and two arc crotch 63 continuously, and the angle β between lead-in chamfered 66 and the arc thin-wall spring 64 is 20 °.

Assembling matrix 67 parts of spring retaining mechanism 6 are enclosed within outward on the plug outer conductor 5; Annulus 7 outer being enclosed within the tight mechanism 6 of springlock; Annulus 7 is metal sleeves of the circular ring type of a heavy wall; The inner surface of annulus 7 plays the banding effect to the arc thin-wall spring 64 of spring retaining mechanism 6, and fixedly the arc thin-wall spring 64.Be the interference tight fit between the assembling matrix 67 of annulus 7 internal diameters and spring retaining mechanism 6; Between the tail end face of annulus 7 and the plug outer conductor 5 corresponding mounting plates also is the interference tight fit, makes between plug outer conductor 5, spring retaining mechanism 6 annuluss 7 threes as a whole through the assembling of interference tight fit.Separate lock barrel 8 and be coated at spring retaining mechanism 6 and annulus 7, be coated at the plug outer conductor 5 and socket outer conductor 9 of part simultaneously; Spring retaining mechanism 6 is arranged in annulus 7 separates lock barrel 8 inner chambers, makes to separate between lock barrel 8 and plug outer conductor 5, annulus 7 external diameters to keep certain clearance.Afterbody at annulus 7 is provided with projection 71, and projection 71 is stuck in the respective grooves of separating on lock barrel 8 inwalls, comes off to prevent release sleeve 8.

Separate the top of lock barrel 8 and inwardly trigger, form wedge shape and separate lock ring 81, wedge shape is separated the lead-in chamfered 66 of lock ring 81 positions corresponding to spring retaining mechanism 6.Wedge shape is separated between two arc crotches 63 of inner top surface 82 positions and spring retaining mechanism 6 of lock ring 81 has certain distance, and this distance can allow wedge shape to separate lock ring 81 to move into place to spring retaining mechanism 6 vertically, realize release.

On socket outer conductor 9 outer surfaces of socket 2, a supporting projections 92 is set; The contact inclined-plane 61 of spring retaining mechanism 6 is owing to the effect of arc thin-wall spring 64 is contacted with on the respective side of this supporting projections 92; Making the angle [alpha] between contact inclined-plane 61 and socket outer conductor 9 outer surfaces is 90 °～125 °; Produce the axial force of an annular and minimum radial load, this radial load is ended the maximum static friction force that divides between tooth 62 and the supporting projections 92 much smaller than hook, when connector connects; Socket 2 is close to plug 1, thereby has guaranteed reliably to be connected between plug 1 and the socket 2 under the non-released state.When connector during in release; The separating force of separating lock barrel 8 acts on the lead-in chamfered 66 of spring retaining mechanism 6; Produce a radial load annular, outside, make arc thin-wall spring 64 outwards open at once, hook end to divide tooth 62 to separate at once with contact between the supporting projections 92; Realization plug 1 separates with socket 2, makes unlocking operation more convenient.
