Description

Technical Field

[0001] The invention relates to the technical field of radio frequency coaxial connectors, and in particular to a quick locking mechanism for an interface of a male radio frequency coaxial connector. Background Art

[0002] The 4.3-10 connector in the prior art includes the following features:

[0003] 1) The electrical and mechanical planes are separated into two independent interfaces, so that when added to the system, its electrical performance will not be affected by the installation conditions;

[0004] 2) Compared with the 7 / 16 DIN connector, the size is reduced by 40%, the weight is reduced by 60%, the structural size is equivalent to the N type, but the power bearing capacity and intermodulation index are better than the N type, and it has the advantages of both N and 7 / 16;

[0005] 3) Excellent electrical performance and extremely low PIM;

[0006] During the development, some manufacturers also designed a quick locking mechanism to replace the conventional thread tightening method in the prior art, but the structure generally adopted is a thinner beryllium copper with punched teeth claw, a beryllium copper C-shaped ring structure or a steel ball structure similar to an aviation plug. However, these methods have poor structural reliability, insufficient axial tensile strength, easy wear and other reasons, resulting in most users continuing to use the thread tightening structure when using the 4.3-10 type connector. To this end, a quick locking mechanism for the male RF coaxial connector interface is proposed. Summary of the invention

[0007] The purpose of the present invention is to solve the above problems and to provide a quick locking mechanism for the interface of a male radio frequency coaxial connector.

[0008] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a male RF coaxial connector interface quick locking mechanism, comprising a male shell body and a fixed sleeve installed on the male shell body; the characteristic is that it also includes an unlocking sleeve movably installed on the fixed sleeve, a buckle movably installed on the fixed sleeve and formed by a plurality of buckle petals, unlocking teeth and locking teeth arranged on the buckle petals, and an unlocking ring arranged on the unlocking sleeve and driven by moving the unlocking sleeve to expand outward to achieve unlocking, and the unlocking sleeve is provided with an unlocking cavity for the buckle to expand outward after being subjected to force.

[0009] Further preferably, the fixing sleeve is provided with a plurality of first windows and second windows adapted to the unlocking teeth and locking teeth on the buckle flap.

[0010] Further preferably, the number of the buckle flaps is not less than two.

[0011] Further preferably, it also includes an anti-slip boss which is arranged on the buckle and located at one end of the locking tooth to prevent the buckle from being detached, and an anti-slip groove which is arranged on the fixing sleeve and matches the anti-slip boss.

[0012] More preferably, it also includes an unlocking inclined surface provided on the unlocking latch tooth and having a guiding effect, and an introduction inclined surface provided on the locking latch tooth and having a guiding effect.

[0013] Further preferably, it also includes a first annular groove and a second annular groove arranged on the buckle, and a first sealing ring and a second sealing ring installed in the first annular groove and the second annular groove to provide a holding force for the contraction of the buckle.

[0014] Further preferably, it also includes a compression boss arranged on the unlocking sleeve, a support step arranged on the fixing sleeve, and a spring installed outside the fixing sleeve and between the compression boss and the support step to provide elasticity to the unlocking sleeve.

[0015] Further preferably, it also includes a positioning step arranged at one end of the unlocking sleeve to limit its position.

[0016] Further preferably, it also includes an inner groove, a sealing groove, and a third sealing ring installed in the sealing groove.

[0017] Further preferably, it also includes a plurality of anti-skid grooves arranged on the outer side of the unlocking sleeve for enhancing the friction resistance of the unlocking sleeve and playing an anti-skid role.

[0018] The beneficial effects of the present invention are as follows: by adopting the unlocking sleeve and the buckle design, the 4.3-10 male connector can be quickly connected and locked with the female socket without using threads, the connector speed is increased by 80%, and it is easy to disassemble and the disassembly speed is fast;

[0019] By innovatively setting an anti-dropout boss on the buckle and setting an anti-dropout groove matching the anti-dropout boss on the fixing sleeve, the anti-dropout boss of the buckle is embedded in the anti-dropout groove of the fixing sleeve. When subjected to axial force, the axial force acts on the steps of the anti-dropout boss and the anti-dropout groove, which can provide greater support force for the connection between the buckle and the fixing sleeve, and the axial holding force can reach more than 1000N.

[0020] By arranging locking teeth and unlocking teeth on the buckle, the unlocking part and the locking part are separated, thereby reducing the wear of the locking part and increasing the service life;

[0021] By arranging the corresponding first window and the second window on the fixing sleeve, the axial position of the buckle is limited by the double windows, so that the axial activity space of the buckle is smaller, thereby reducing the axial activity space of the socket inside the buckle, making the locking more reliable;

[0022] The buckle is composed of multiple separate buckle petals, each of which can achieve clamping. When one or more buckle petals fail due to damage, the remaining buckle petals can still achieve the clamping effect, thereby greatly improving the fault tolerance of the buckle failure.

[0036] By adopting the unlocking sleeve 3 and the buckle 4 design, the 4.3-10 male connector can be quickly connected and locked with the female socket without using threads, the connector speed is increased by 80%, and it is easy to disassemble and the disassembly speed is fast;

[0037] By providing a locking tooth 43 and an unlocking tooth 42 on the buckle 4, the unlocking part and the locking part are separated, thereby reducing the wear of the locking part and increasing the service life;

[0038] The buckle 4 is composed of multiple individual buckle flaps 41, and each individual buckle flap 41 can achieve clamping. When one or more buckle flaps 41 fail due to damage, the remaining buckle flaps 41 can still achieve the clamping effect, thereby greatly improving the fault tolerance of the buckle 4 to failure.

[0039] In one embodiment, the fixing sleeve 2 is provided with a plurality of first windows 21 and second windows 22 adapted to the unlocking teeth 42 and the locking teeth 43 on the buckle flap 41;

[0040] By providing corresponding first window 21 and second window 22 on the fixing sleeve 2, the axial position of the buckle 4 is limited by the double windows, so that the axial activity space of the buckle 4 is smaller, thereby reducing the axial activity space of the socket inside the buckle 4 and making the locking more reliable.

[0041] In one embodiment, it also includes an anti-dropout boss 6 disposed on the buckle 4 and located at one end of the locking tooth 43 to prevent the buckle 4 from being disengaged, and an anti-dropout groove 61 disposed on the fixing sleeve 2 and adapted to the anti-dropout boss 6;

[0042] By innovatively setting an anti-dropout boss 6 on the buckle 4 and an anti-dropout groove 61 matched with the anti-dropout boss 6 on the fixing sleeve 2, the anti-dropout boss 6 of the buckle 4 is embedded in the anti-dropout groove 61 of the fixing sleeve 2. When subjected to axial force, the axial force acts on the steps of the anti-dropout boss 6 and the anti-dropout groove 61, which can provide greater supporting force for the connection between the buckle 4 and the fixing sleeve 2, and the axial holding force can reach more than 1000N.

[0043] In one embodiment, it also includes an unlocking inclined surface 421 provided on the unlocking latch 42 for guiding, and an introduction inclined surface 431 provided on the locking latch 43 for guiding;

[0044] By setting the unlocking inclined surface 421, the movement of the unlocking ring 5 forms an outward squeezing force on the unlocking latch 42, so that it expands outward into the unlocking cavity 51, and plays a guiding role in the contact between the unlocking ring 5 and the unlocking latch 42;

[0045] The introduction slope 431 guides the contact between the socket and the locking tooth 43 when the socket is inserted, and forms an outward squeezing force on the locking tooth 43 during the pushing process, so that the buckle 4 expands outward.

[0046] In one embodiment, it further includes a first annular groove 7 and a second annular groove 71 provided on the buckle 4, and a first sealing ring 72 and a second sealing ring 73 installed in the first annular groove 7 and the second annular groove 71 to provide a holding force for the contraction of the buckle 4;

[0047] The first annular groove 7 and the second annular groove 71 are provided to limit the installation positions of the first sealing ring 72 and the second sealing ring 73;

[0048] The first sealing ring 72 and the second sealing ring 73 are provided to connect a plurality of buckle petals 41 and provide a retaining force for the contraction of the buckle 4, so that the buckle 4 can automatically contract inward and reset when not subjected to an outward squeezing force.

[0049] In one embodiment, it also includes a compression boss 31 disposed on the unlocking sleeve 3, a support step 23 disposed on the fixing sleeve 2, and a spring 24 installed outside the fixing sleeve 2 and between the compression boss 31 and the support step 23 to provide elasticity to the unlocking sleeve 3;

[0050] The arrangement of the compression boss 31 and the support step 23 is used to limit the installation position of the spring 24, and is also used as an extrusion member and a support member when the spring 24 is extruded; the arrangement of the spring 24 provides elasticity for the unlocking sleeve 3, so that it can automatically reset after moving backwards through the reset force of the spring 24.

[0051] In one embodiment, a positioning step 32 is further included at one end of the unlocking sleeve 3 to limit its position; the positioning step 32 is provided to limit the forward movement of the unlocking sleeve 3.

[0052] In one embodiment, it also includes an inner groove, a sealing groove 26 and a third sealing ring 27 installed in the sealing groove 26 provided on the fixing sleeve 2; the setting of the inner groove plays a role in positioning the connection position of the fixing sleeve 2 and the male housing 1; the setting of the sealing groove 26 plays a role in limiting the installation position of the third sealing ring 27; the setting of the third sealing ring 27 is used to increase the connection tightness between the fixing sleeve 2 and the male housing 1.

[0053] In one embodiment, it also includes a plurality of anti-skid grooves 8 arranged on the outer side of the unlocking sleeve 3 to enhance the friction resistance of the unlocking sleeve 3 and play an anti-skid role; through the arrangement of the plurality of anti-skid grooves 8, the pushing of the unlocking sleeve 3 is enhanced to avoid slipping when pushing the unlocking sleeve 3 and affecting the unlocking.

[0054] The present invention is connected when:

[0055] Directly align the female socket with the ejector pin and insert it. During the insertion process, the front end of the socket contacts the introduction slope 431 of the locking tooth 43. During the continuous insertion process, an outward squeezing force is applied to the locking tooth 43 along the introduction slope 431, driving the buckle 4 to expand outward until the female socket is inserted into place and the locking tooth 43 is no longer subjected to the outward squeezing force. At this time, the contraction force provided by the first sealing ring 72 and the second sealing ring 73 to the buckle 4 drives the buckle 4 to contract inwardly to the female socket of the column, and the quick locking of the female socket is completed at this time.

[0056] When disassembling, it is only necessary to pull the unlocking sleeve 3 backwards. During the backward movement, the unlocking sleeve 3 squeezes the spring 24 by compressing the boss 31, and at the same time drives the unlocking ring 5 to contact the unlocking inclined surface 421 of the unlocking tooth 42, and applies an outward squeezing force to the unlocking tooth 42 during the continuous backward movement of the unlocking sleeve 3, squeezing the buckle 4 outward to expand it into the unlocking cavity 51. At this time, the locking tooth 43 no longer limits the female socket. At this time, unlocking is achieved, and the female socket can be directly pulled out to complete disassembly.

[0057] The protection scope of the present invention is not limited to the above embodiments and their variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment all fall within the protection scope of the present invention.
