Description

Technical Field

[0001] This utility model relates to an SMA type radio frequency coaxial connector, specifically an SMA type radio frequency coaxial connector utilizing an elastic locking mechanism. Background Technology

[0002] SMA type RF coaxial connectors are widely used in the RF and microwave fields, and are known for their miniaturization, high frequency and excellent electrical performance.

[0003] When connecting, male and female connectors are often used. The existing connection is generally achieved by inserting the conductor pin of the male connector into the inside of the female connector, so that the conductor pin of the male connector is connected to the female connector and energized. Then, the male and female connectors are connected by snap-fit ​​or threaded connection.

[0004] However, existing male connectors do not have a flexible, retractable clearance mechanism for their conductor pins during connection. When the conductor pin is inserted into the female connector, if it does not initially touch the inside of the female connector's hole, the conductor pin will collide with the metal material around the hole, thus damaging the conductor pin.

[0005] Therefore, the existing method of connecting male and female connectors by inserting conductor pins still has certain limitations. Utility Model Content

[0006] The purpose of this invention is to provide an SMA type RF coaxial connector that utilizes an elastic locking mechanism to address the limitations mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An SMA type radio frequency coaxial connector utilizing an elastic locking mechanism includes a male connector and a female connector, wherein the male connector has an internal protective mechanism.

[0009] The protection mechanism includes a male connector that protects the conductor of the coaxial connector within its interior, and the conductor retracts into the male connector upon impact.

[0010] The SMA type RF coaxial connector using elastic locking as described above: the female connector has a female connector head inside, a connecting tenon is provided on the surface of one end of the female connector head, and a conductive groove is also provided in the middle position of one end of the female connector head.

[0011] The SMA type RF coaxial connector using elastic locking as described above: the male connector has an inner cylinder inside, and the inner cylinder has a locking block inside.

[0012] As described above, the SMA type RF coaxial connector utilizing an elastic locking mechanism has the male connector movably disposed inside the locking block, and the male connector can retract into the locking block, and the male connector can also rotate inside the locking block.

[0013] As described above, the SMA type RF coaxial connector utilizing elastic locking has the following features: a locking head is provided on the peripheral surface of the male connector, a locking block is fitted onto the surface of the male connector, and the locking head and the locking block are engaged; a spring is provided inside the inner cylinder, one end of the spring abuts against the inner wall of the inner cylinder, and the other end of the spring abuts against the locking head; and the spring is initially in a pre-compressed state inside the inner cylinder.

[0014] The SMA type RF coaxial connector using elastic locking as described above: one end of the male connector has a connecting groove, and the size of the connecting groove is adapted to the connecting tenon.

[0015] As described above, the SMA type RF coaxial connector utilizing elastic locking has a protective groove at one end, and a guide pin is slidably disposed inside the male connector, with one end of the guide pin connected via a wire.

[0016] The SMA type RF coaxial connector using the elastic locking mechanism described above: the guide pins and conductive grooves cooperate to electrically connect the male connector and the female connector.

[0017] Compared with the prior art, the beneficial effects of this utility model are: by providing a protective groove inside the male connector, when the guide pin touches other hard metal materials, it will slide inside the protective groove, thereby driving the snap-fit ​​connector to squeeze the spring through the male connector, thus further compressing the spring, and the guide pin will retract inward inside the protective groove, thereby playing a certain role in protecting the guide pin.

[0018] This utility model is also easy to install. When it is necessary to quickly connect the guide pin and the conductive groove, the female connector squeezes the male connector, and the male connector drives the snap-fit ​​connector to squeeze the spring inside the snap-fit ​​block. At this time, the snap-fit ​​connector separates from the snap-fit ​​block. Then, the female connector is rotated, and the female connector will also drive the male connector to rotate, so that the relative position of the snap-fit ​​connector and the snap-fit ​​block is rotated. At this time, the snap-fit ​​groove on the snap-fit ​​block separates from the snap-fit ​​connector. The snap-fit ​​connector rotates to the hollow position in the middle. At this time, under the action of the spring, the snap-fit ​​connector can be pushed, and the snap-fit ​​connector pushes the male connector. The male connector pushes the guide pin to quickly insert into the interior of the conductive groove, so that the male connector and the female connector are electrically connected.

[0019] This utility model also features easy installation. The connecting tenon is forcefully inserted into the connecting groove, using a traditional mortise and tenon structure, which allows the male connector and the female connector to be quickly, conveniently, and stably connected together.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figures 1-6 As an embodiment of this utility model, the SMA type radio frequency coaxial connector utilizing elastic locking includes a male connector 1 and a female connector 8, wherein the male connector 1 is provided with a protective mechanism inside.

[0029] The protection mechanism includes a male connector 4, which can protect the conductor of the coaxial connector inside, and the conductor can retract into the male connector 4 when it is hit.

[0030] In this embodiment, when the male connector 1 and the female connector 8 need to be electrically connected, a male connector head 4 is provided inside the male connector 1, and the male connector head 4 has the effect of protection and clearance. When the conductor pin inside the male connector head 4 collides with other metal materials, the conductor pin will enter the interior of the male connector head 4, thereby making the male connector head 4 form a protection mechanism for the conductor pin.

[0031] As a further embodiment of this utility model, the female connector 8 is provided with a female connector head 9 inside, and a connecting tenon 901 is provided on the surface of one end of the female connector head 9. A conductive groove 902 is also provided in the middle position of one end of the female connector head 9.

[0032] In this embodiment, a connecting tenon 901 is installed at one end of the female connector 9, using a traditional mortise and tenon structure, so that the connecting tenon 901 is squeezed into the interior of the male connector 4 to complete the connection.

[0033] As a further embodiment of this utility model, the male connector 1 is provided with an inner cylinder 2, and the inner cylinder 2 is provided with a snap-fit ​​block 3.

[0034] In this embodiment, an inner cylinder 2 is installed inside the male connector 1, and a snap-fit ​​block 3 is installed inside the inner cylinder 2.

[0035] As a further embodiment of this utility model, the male connector 4 is movably disposed inside the snap-fit ​​block 3, and the male connector 4 can retract into the snap-fit ​​block 3, and the male connector 4 can also rotate inside the snap-fit ​​block 3.

[0036] In this embodiment, the male connector 4 can move inside the snap-fit ​​block 3.

[0037] As a further embodiment of this utility model, a snap-fit ​​connector 5 is provided on the peripheral surface of the male connector 4, and the snap-fit ​​block 3 is sleeved on the surface of the male connector 4, and the snap-fit ​​connector 5 and the snap-fit ​​block 3 are snapped together. A spring 6 is provided inside the inner cylinder 2, one end of the spring 6 abuts against the inner wall of the inner cylinder 2, and the other end of the spring 6 abuts against the snap-fit ​​connector 5. The spring 6 is in a pre-compressed state in the initial state inside the inner cylinder 2.

[0038] As a further embodiment of this utility model, one end of the male connector 4 is provided with a connecting groove 401, and the size of the connecting groove 401 is adapted to the connecting tenon 901.

[0039] Combining the above two embodiments, when quick installation is required, the connecting tenon 901 is forcefully squeezed into the connecting groove 401, thereby connecting the male and female connectors through the mortise and tenon connection. When the connecting tenon 901 is squeezed into the connecting groove 401, the female connector 9 can also drive the male connector 4 to rotate. When the guide pin 7 needs to be installed quickly, the female connector 9 is squeezed into the direction of the male connector 4, thereby driving the male connector 4 to slide inside the snap-fit ​​block 3. At the same time, the snap-fit ​​connector 5 will also squeeze the spring 6 inside the inner cylinder 2, so that the spring 6 has a certain elastic potential energy. When the snap-fit ​​connector 5 separates from one end of the snap-fit ​​block 3, the male connector 4 is rotated so that the snap-fit ​​connector 5 rotates to the middle of the two snap-fit ​​grooves on the snap-fit ​​block 3. At this time, under the reset force of the spring 6, the spring 6 will push the snap-fit ​​connector 5, and the snap-fit ​​connector 5 will push the male connector 4 to slide quickly inside the snap-fit ​​block 3 towards the female connector 9, thereby driving the guide pin 7 to quickly enter the interior of the female connector 9.

[0040] It should be noted that since the male connector 4 has protruded a portion from the snap-fit ​​block 3 relative to the initial state, and the guide pin 7 is located inside the male connector 4, it will also move towards the position of the female connector 9 accordingly, so that the guide pin 7 is snapped into the inside of the female connector 9.

[0041] In conjunction with the first embodiment,

[0042] As a further embodiment of this utility model, a protective groove 402 is provided at one end of the male connector 4, and a guide pin 7 is slidably disposed inside the male connector 4, with one end of the guide pin 7 connected by a wire.

[0043] In this embodiment, in conjunction with the previous embodiment, the guide pin 7 slides inside the protective groove 402. When the male connector 4 moves, it also drives the guide pin 7 to move through the protective groove 402. Because the protective groove 402 is provided inside the male connector 4, when the guide pin 7 touches other hard metal materials, it slides inside the protective groove 402. This causes the male connector 4 to drive the snap-fit ​​connector 5 to compress the spring 6, further compressing the spring 6. Consequently, the guide pin 7 retracts inward within the protective groove 402, thus providing a certain degree of protection for the guide pin 7.

[0044] As a further embodiment of this invention, the guide pin 7 and the conductive groove 902 cooperate to electrically connect the male connector 1 and the female connector 8.

[0045] In this embodiment, combining the two embodiments described above, when the guide pin 7 moves toward the female connector 9, it is electrically connected to the guide pin 7 through the conductive groove 902 on it, thereby making the male connector 1 and the female connector 8 electrically connected together.

[0046] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
