Description
Technical field
The present invention relates to coaxial electric coupler, this connector is suitable for advancing latched interconnect (push-on locking interconnection) with the part of interface, also be suitable for and the AN connector that is threaded the attaching nut, for example N type public connector (male connector) engages.
Background technology
The electric connector that uses in RF the uses standardization that become is used from the device of different manufacturers mutually allowing.Be used for the more standardization connector of high power levels,, adopt and the thread jacket ring that is formed at the threads engaged in the recessed portion external diameter at projection as 7/16Din, SMA and N Connector.
The thread jacket ring need change multi-turn and be in connected condition fully, and this is time-consuming and requires the user to make with the hands and/or spanner.Connect to need under the situation about often changing, for example in terminal block or when testing or in mobile device, screwing on and unclamping the thread jacket ring becomes burden.Need the space between each connector and/or surrounding structure, to allow to stretch into spanner and/or hand, this has just limited the application of connector in high density structures.
In addition, thread ring is interconnected in rotation aspect and the connector interlocking that is interconnected, and this relatively rotates with respect to each other with regard to the equipment that has limited any relevant cables and/or connected.
Utilize alternative thread jacket ring such as spring detent to simplify connector, wherein spring detent is subjected to bias voltage, to block screw thread, and the balance that keeps interconnecting, thus under certain interconnect strength, connecting easily.But interconnect strength may reduce during repeated use.
That competition in the electric connector industry has concentrated on is easy to use, on the reliability of electrical interconnection characteristic and connector.The factor of business success also comprises the interoperability of standardization connector, and reduces manufacturing, material and installation cost.
Thereby, the object of the present invention is to provide a kind of attachment unit interface, it has overcome the defective of prior art.

Embodiment
The present invention will be described in conjunction with Fig. 1-5, and in exemplary embodiment of the present invention, female connectors is compatible mutually with standard N type public connector.Those skilled in the art are to be understood that, the present invention can be applied to other standardization or proprietary attachment unit interface equally, and at least one in the end of feasible corresponding protrusion of this attachment unit interface and recessed portion can be formed with cannelure and/or interior protruding end barb on the inside diameter surface of protrusion or recessed portion.
As shown in Figure 1, public connector 2 has cylindrical shape outer conductor 4.Supported by insulator 6, interior conductive pin 8 is positioned at outer conductor 4 inside coaxially.The spring dog collar 10 that is shown in further detail among Fig. 2 for example is engaged on the external diameter of outer conductor 4 by the interference engagement on the projection shoulder 14 of outer conductor 4, and this spring dog collar 10 has a plurality of isolated spring detents 12.
Spring detent 12 forms has proximal extension portion 16, and it is transited into remote extension portion 18 with inclined surface 20.Spring dog collar 10 is reducing to the transition position near the remote extension portion 18 of inclined surface 20 at the internal diameter at proximal extension portion 16 places.Evagination barb 22 is formed at the far-end of spring detent 12.
The collar 24 around spring dog collar 10 can move along the longitudinal axis of connector, and the interior prominent surface of the collar 24 is maintained between evagination barb 22 and the inclined surface 20.In order to have the effect that holds of improved spring detent, the collar can be formed with a plurality of evagination ribs 26 or other forms of catch surface around external diameter.The collar 24 has a plurality of inwardly outstanding retainers 28 between one or more spring detent 12.Retainer 28 is against ring 30, and this ring is pushed to the interconnected ends 32 of public connector 2 against the spring 34 of shoulder 14, and can slide along outer conductor 4 under spring detent 12.The ring 30 and shoulder 14 between extruded spring 34 towards interconnected ends 32 bias rings 30, thereby to the interconnected ends 32 bias voltage collars 24.Along with the collar 24 overcomes spring 34 and compresses spring 34 and move away from connecting end 32, ring 30 moves along outer conductor 4 under proximal extension portion 16, and the interior prominent surface on the internal diameter of the collar 24 engages with the inclined surface 20 of spring detent 12 between retainer 28.As shown in Figure 3, along with inclined surface 20 is engaged, spring detent 12 is retracted, and conductor 4 inwardly is activated outward.
Below with reference to Fig. 4, in the present embodiment, when public connector 2 inserts the interconnected ends 32 of female connectors 36 under its spring detent 12 contraction states, barb 22 cross female connectors 36 hole 40 front end and extend internally, till the front end of outer conductor 4 pushes up the bottom that is formed at the respective step 42 in 40 internal diameters of hole.When inserting, interior conductive pin 8 cooperates with the corresponding interior contact 44 of public connector 38 equally, and for example, contact 44 is formed with spring contact 46 in this, and the inside bias voltage of described spring contact is firmly to hold the leading part of the interior conductive pin 8 with reduction radius.
When being separated with inclined surface 20 when allowing spring 34 to make the collar 24 return forward facing position, spring detent 12 returns stable position, and barb 22 is inserted in the respective annular groove 48 in the internal diameter that is formed at hole 40 and/or is resisted against on the interior protruding end barb of female connectors 36.When allowing the collar 24 withdrawals, ring 30 turns back to the position under the remote extension portion 18 of spring detent 12 equally, moves inward to prevent spring detent 12, otherwise can allow barb 22 to separate with cannelure 48.Thus, as shown in Figure 5, public connector 2 and female connectors 36 interlockings are up to overcoming the spring 34 withdrawal collars 24 once more.
If the corresponding surface of outer and female connectors, as barb 22 and cannelure 48 and spring contact 46 and pin 8, form respectively and do not have rough surface, then the public connector 2 of interlocking and female connectors 36 can rotate relative to one another, and can not worsen electrical interconnection, thereby provide easy manipulation for the cable and/or the device of interconnection.
When the connector interlocking, the leading edge of the collar 24 can be suitable for only covering the very short part of the interconnected ends 32 external diameter leading edges of female connectors 36.Can form screw thread 50 with around the external diameter of the female connectors of the region separation that covers by the collar 24.Thereby for example, as shown in Figure 5, female connectors 36 can be suitable for admitting the traditional public connector that utilizes attaching nut 52 in addition easily, and this attaching nut 52 matches with screw thread 50.
With the measure permanent and/or semipermanent interconnection of the interior and outer conductor of connector and coaxial cable and/or device is known in the field, for example welding, crimping and/or mechanical compress.Therefore, do not further specify according to aspect these of the connector with interconnected ends of the present invention at this.
The invention provides a kind of simplification and have cost-efficient attachment unit interface, it has very thin profile and minimized materials demand.The present invention allows the user also to connect securely fast and disconnects interconnection, and need not to carry out time-consuming stubborn screw thread and/or auxiliary tools.The present invention needs minimum discrete component and does not rely on special spring structure.In addition, the present invention can be suitable for compatible mutually with traditional attaching nut's connector construction.
