[0031] The utility model is further described below in conjunction with specific embodiments and drawings.

[0032] See Figure 1-4 As shown, an annular locking spring piece can be formed by wrapping a metal sheet in a circle, or by stamping a metal tube.

[0033] In this embodiment, the annular locking spring 1 is formed by a metal sheet wrapped in a circle, and its specific structure is as follows:

[0034] The annular locking spring piece 1 comprises an annular body 11, a plurality of barbed pieces 12 formed at the rear end of the annular body 11 and distributed in an annular shape, and a plurality of elastic pressing pieces 13 formed by inwardly stamping and bending along the outer surface of the annular body 11 and distributed in an annular shape, wherein the barbed piece 12 extends outwardly and tilts, while the elastic pressing piece 13 extends forward, and the end of the elastic pressing piece 13 is bent outwardly and turned to form a blocking piece 14, and the blocking piece 14 has a locking buckle pressing plane 141 in a vertical direction. Figure 5-12As shown, the annular locking spring piece 1 in the utility model is passed through the inner circular hole 21 of the plastic shell 2, and is sleeved on the outside of the outer conductor 3 passed through the inner circular hole 21 in the plastic shell 2, thereby replacing the clamping ring in the background technology for locking and positioning the outer conductor 3 in the plastic shell 2, wherein the front end face of the annular main body 11 contacts the thrust step surface 211 of the front inner wall of the inner circular hole 21 in the plastic shell 2, effectively preventing the annular locking spring piece 1 from moving forward, and the barb piece 12 is clamped and positioned with the rear inner wall of the inner circular hole 21, effectively preventing the annular locking spring piece 1 from retreating, thereby ensuring that the annular locking spring piece 1 is positioned in the inner circular hole 21, and the end of the elastic pressing piece 13 presses against The outer surface of the outer conductor 3 is used to support and position the outer conductor 3, so that the outer conductor 3 is more stably installed in the plastic shell 2, and the locking pressing plane 141 of the vertical direction of the baffle 14 is in contact with the rear end surface of the locking portion outside the outer conductor 3, thereby preventing the outer conductor 3 from retreating, thereby achieving the purpose of excellent locking effect, so that there is no need to open a fixing window on the outside of the plastic shell for the installation of a clamping ring for locking the outer conductor 3, thereby avoiding the risk of water / water vapor entering from the gap between the fixing window and the clamping ring, so as to achieve a better waterproof effect, which can not only improve the service life of the outer conductor 3, but also improve the performance of the connector, thereby having extremely strong market competitiveness.

[0035] The barbed pieces 12 are evenly distributed along the circumference. The elastic pressing pieces 13 are evenly distributed along the circumference.

[0036] In order to make the annular locking spring piece 1 and the outer conductor 3 in stable contact, and thus ensure that the annular locking spring piece 1 can be installed more stably between the plastic shell 2 and the outer conductor 3, the inner side surface of the elastic pressing piece 13 is also set to a circular arc surface 131. The circular arc surface 131 of the elastic pressing piece 13 matches the curvature of the outer surface of the outer conductor 3, so that the circular arc surface 131 can completely cover the outer surface of the outer conductor 3, forming a surface contact or a line contact, and the increased contact area, so that the annular locking spring piece 1 and the outer conductor 3 are in stable contact, and the annular locking spring piece 1 can be installed more stably between the plastic shell 2 and the outer conductor 3.

[0037] In order to make the annular body 11 more stably installed in the inner circular hole 21 of the plastic shell 2, the following design is made: the front end and the rear end of the annular body 11 are respectively formed with a first annular convex rib 15 and a second annular convex rib 16 protruding outward, and the outer surfaces of the first annular convex rib 15 and the second annular convex rib 16 are flush. When the annular locking spring 1 is installed in the inner circular hole 21 of the plastic shell 2, since the outer surfaces of the first annular convex rib 15 and the second annular convex rib 16 are flush and protrude from the annular body 11, the outer surfaces of the first annular convex rib 15 and the second annular convex rib 16 are in line contact with the hole wall of the inner circular hole 21, so that the front and rear ends of the annular body 11 are stably positioned in the inner circular hole 21, ensuring that the entire annular locking spring 1 is more stably installed in the inner circular hole 21 of the plastic shell 2.

[0038] Among them, the cross-sections of the first annular convex rib 15 and the second annular convex rib 16 are both arc-shaped, so that the outer surfaces of the first annular convex rib 15 and the second annular convex rib 16 can better form linear contact with the hole wall of the inner circular hole 21, and the entire annular locking spring piece 1 can be more smoothly installed in the inner circular hole 21.

[0039] The rear end of the annular body 11 is also bent to form an extension piece 17 that extends obliquely backward and is in the shape of a trumpet. The extension piece 17 is punched to form a plurality of notches 171, so that a barbed piece 12 is formed between two adjacent notches 171, so that the barbed piece 12 has sufficient strength. The barbed piece 12 has better elastic deformation ability, so that the barbed piece 12 can be better pressed into the axial direction with the inner circular hole 21 to hold and position it, and firmly stuck in the plastic shell 2, thereby effectively preventing the annular locking spring piece 1 from accidentally retreating.

[0040] Combination Figure 1-12As shown, the utility model also proposes a connector locking structure, which includes a plastic shell 2 and an outer conductor 3 inserted into the inner circular hole 21 of the plastic shell 2, wherein the plastic shell 2 and the outer conductor 3 are locked and positioned by the above-mentioned annular locking spring piece 1, wherein a thrust step surface 211 is provided on the front inner wall of the inner circular hole 21, and the front end of the annular body 11 abuts against the thrust step surface 211, and the barb piece 12 is clamped and positioned with the rear inner wall of the inner circular hole 21, and a locking portion is provided on the outside of the outer conductor 3, and the front end face of the locking portion abuts against the thrust step surface 211, and the end of the elastic pressing piece 13 presses against the outer surface of the outer conductor 3, and the locking pressing plane 141 of the end baffle 14 of the elastic pressing piece 13 abuts against the rear end face of the locking portion to lock the outer conductor 3. That is to say, the utility model adopts an annular locking spring piece 1 to pass through the inner circular hole 21 of the plastic shell 2, and is sleeved on the outside of the outer conductor 3 passed through the inner circular hole 21 in the plastic shell 2, thereby replacing the clamping ring in the background technology to lock and position the outer conductor 3 in the plastic shell 2, wherein the front end face of the annular main body 11 and the thrust step surface 211 of the front inner wall of the inner circular hole 21 in the plastic shell 2 effectively prevent the annular locking spring piece 1 from moving forward, and the barb piece 12 is clamped and positioned with the rear inner wall of the inner circular hole 21, effectively preventing the annular locking spring piece 1 from retreating, thereby ensuring that the annular locking spring piece 1 is positioned in the inner circular hole 21, and the end of the elastic pressing piece 13 presses against The outer surface of the outer conductor 3 is used to support and position the outer conductor 3, so that the outer conductor 3 is more stably installed in the plastic shell 2, and the locking pressing plane 141 of the vertical direction of the baffle 14 is in contact with the rear end surface of the locking portion outside the outer conductor 3, thereby preventing the outer conductor 3 from retreating, thereby achieving the purpose of excellent locking effect, so that there is no need to open a fixing window on the outside of the plastic shell for the installation of a clamping ring for locking the outer conductor 3, thereby avoiding the risk of water / water vapor entering from the gap between the fixing window and the clamping ring, so as to achieve a better waterproof effect, which can not only improve the service life of the outer conductor 3, but also improve the performance of the connector, thereby having extremely strong market competitiveness.

[0041] The locking portion includes at least one of the following two structures:

[0042] The first structure: the locking portion is a locking piece 31 stamped and formed on the outer surface of the outer conductor 3, wherein the front end of the rear locking portion 312 is integrally connected with the rear side of the front locking portion 311 to form a whole.

[0043] The front end face and the rear end face of the locking piece 31 both protrude from the outer surface of the outer conductor 3, and can be easily contacted with the thrust step surface 211 and the lock pressing plane 141, respectively. The front end face of the locking piece 31 mostly protrudes from the outer surface of the outer conductor 3, while the lower side of the front end face of the locking piece 31 does not protrude from the outer surface of the outer conductor 3, but contacts the puncture surface of the outer conductor 3 in the vertical direction. The front end strength of the locking piece 31 of this structure is stronger and it does not deform, so that the function of the locking piece 31 will not fail, thereby ensuring the realization of the locking function.

[0044] The locking piece 31 includes a front locking portion 311 formed by piercing and stretching the outer conductor 3 and a rear locking portion 312 integrally connected to the rear side of the front locking portion 311, and both sides of the front locking portion 311 are integrally connected to the outer conductor 3, the rear locking portion 312 is pierced on the outer conductor 3 and bent outwardly, and the rear end of the rear locking portion 312 is inclined upward and protrudes outside the surface of the outer conductor 3, and the two side surfaces of the rear locking portion 312 are connected to the outer conductor 3. A gap 301 is formed therein so that the rear locking portion 312 has a certain elastic deformation ability, that is, the rear locking portion 312 can be squeezed downward and deformed, and an outward elastic restoring force is formed after deformation, so that the rear end face of the rear locking portion 312 is in contact with the lock buckle pressing plane 141 more stably, and the locking effect is better; the rear end face of the rear locking portion 312 is in contact with the lock buckle pressing plane 141, and the front end face of the front locking portion 311 is in contact with the thrust step surface 211.

[0045] The rear end face of the rear locking portion 312 is arc-shaped and vertically distributed, and the center of the rear end face of the rear locking portion 312 is coaxial with the center of the outer conductor 3. The arc angle of the outer circle of the rear end face of the rear locking portion 312 is 30-100°. In this embodiment, the arc angle of the outer circle of the rear end face of the rear locking portion 312 is about 60°.

[0046] In addition, the width A of the locking piece 31 is larger than the spacing B between two adjacent blocking pieces 14, so that after the outer conductor 3 is rotated at any angle, the locking pressing plane 141 of at least one blocking piece 14 contacts the rear end face of the locking piece 31, thereby achieving 360-degree stop, ensuring sufficient pull-off force, and achieving a better locking effect. In other words, no matter from which angle the outer conductor 3 is inserted, the annular locking spring piece 1 can firmly clamp the rear end face of the locking piece 31 of the outer conductor 3, ensuring sufficient pull-off force.

[0047] For details, please refer to Fig. 9 As shown, the locking piece 31 is at the 12 o'clock direction, and the locking pressing planes 141 of the two blocking pieces 14 are in contact with the rear end surface of the locking piece 31, thereby realizing the anti-retraction function.

[0048] See also Fig.10 As shown, at the 1 o'clock direction of the locking piece 31 , only one locking pressing plane 141 of the blocking piece 14 contacts the rear end surface of the locking piece 31 , thereby realizing the anti-retraction function.

[0049] See also Fig.11 As shown, at the 2 o'clock direction of the locking piece 31 , only one locking pressing plane 141 of the blocking piece 14 contacts the rear end surface of the locking piece 31 , thereby realizing the anti-retraction function.

[0050] See also Fig.12As shown, the locking piece 31 has two locking pressing planes 141 of the blocking pieces 14 in contact with the rear end surface of the locking piece 31 at the 3 o'clock direction, thereby realizing the anti-retraction function.

[0051] When the locking piece 31 is at the 4, 5, 6, 7, 8, 9, 10, 11, and 12 o'clock directions, at least one locking pressing plane 141 of the blocking piece 14 contacts the rear end surface of the locking piece 31, thereby achieving 360-degree stop and achieving a better locking function.

[0052] The second structure: the locking portion is an annular boss stamped on the outer surface of the outer conductor 3. The front end surface of the annular boss contacts the thrust step surface 211, and the rear end surface of the annular boss contacts the locking buckle pressing plane 141, thereby locking the outer conductor 3.

[0053] This embodiment adopts the first structure mentioned above. Because the locking portion is a locking plate 31 stamped and formed on the outer surface of the outer conductor 3, relative to the formed annular boss, the outer surface and the inner surface of the outer conductor are both straight and smooth in the axial direction, so that the high-frequency characteristic impedance matching fluctuation of the outer conductor is small, and then the outer conductor can form an impedance matching of a specific specification with the inner insulator and the inner conductor arranged inside it, so as to meet the use requirements of the connector and ensure product quality.

[0054] In summary, the utility model adopts an annular locking spring piece 1 which is passed through the inner circular hole 21 of the plastic shell 2, and is sleeved on the outside of the outer conductor 3 passed through the inner circular hole 21 in the plastic shell 2, thereby replacing the clamping ring in the background technology for locking and positioning the outer conductor 3 in the plastic shell 2, wherein the front end face of the annular main body 11 contacts the thrust step surface 211 of the front inner wall of the inner circular hole 21 in the plastic shell 2, effectively preventing the annular locking spring piece 1 from moving forward, and the barb piece 12 is clamped and positioned with the rear inner wall of the inner circular hole 21, effectively preventing the annular locking spring piece 1 from retreating, thereby ensuring that the annular locking spring piece 1 is positioned in the inner circular hole 21, and the end of the elastic pressing piece 13 presses against the inner circular hole 21. On the outer surface of the outer conductor 3, the outer conductor 3 is supported and positioned, so that the outer conductor 3 is more stably installed in the plastic shell 2, and the locking pressing plane 141 of the vertical direction of the baffle 14 is in contact with the rear end surface of the locking portion outside the outer conductor 3, thereby preventing the outer conductor 3 from retreating, thereby achieving the purpose of excellent locking effect, so that there is no need to open a fixing window on the outside of the plastic shell for the installation of a clamping ring for locking the outer conductor 3, thereby avoiding the risk of water / water vapor entering from the gap between the fixing window and the clamping ring, so as to achieve a better waterproof effect, which can not only improve the service life of the outer conductor 3, but also improve the performance of the connector, thereby having extremely strong market competitiveness.
