Coaxial connector and outer conductor

Abstract

The present invention relates to the field of connectors, and in particular to a coaxial connector and an outer conductor. The coaxial connector comprises an outer conductor, an insulator, and an inner conductor coaxially sleeved together, with the mating end of the outer conductor as the front end. The outer conductor comprises a ring sleeve and a spring claw arranged at the front end of the ring sleeve. A plurality of spring claws are arranged at intervals along the circumference of the ring sleeve, and the spring claw has a spring claw convex portion protruding outward. The outer conductor also comprises a protective ring in front of the spring claw, and a connecting arm is provided between two adjacent spring claws. The front ends of all connecting arms are connected to the protective ring. The outer diameter of the protective ring is larger than the diameter of the circle where the front end of each spring claw is located, and the outer diameter of the protective ring is smaller than the diameter of the circle where the outermost side of each spring claw convex portion is located. Since the outer diameter of the protective ring is larger than the diameter of the circle where the front end of each spring claw is located, when the coaxial connector is mated with the adapter connector, the protective ring protects the front end of the spring claw to prevent the front end of the spring claw from contacting the adapter connector, thereby ensuring that the spring claw will not be damaged.

Description

Technical Field

[0001] The present invention relates to the field of connectors, and in particular to a coaxial connector and an outer conductor. Background Art

[0002] In today's electronic communications field, such as voice transmission, data transmission, and image transmission, coaxial connectors are required. Coaxial connectors can be used to connect circuit boards, circuit boards and modules, and modules and modules.

[0003] A Chinese invention patent application with application publication number CN102157869A discloses a radio frequency coaxial connector, including a plug, which includes an outer conductor, an insulator and an inner conductor of a coaxial sleeve. The outer conductor includes a ring sleeve and a spring claw arranged at the front end of the ring sleeve, with the mating end of the plug as the front end. A plurality of spring claws are arranged at intervals along the circumference of the ring sleeve, and the spring claws have a spring claw protrusion protruding outward.

[0004] In the above technology, when the plug and socket are plugged together, the front end of the outer conductor's claw enters the cavity of the socket first. Since it is not easy to ensure the coaxiality of the plug and socket during the plugging process, the front end of the claw is likely to collide with the plug end of the socket, which may cause the claw to be damaged. Summary of the Invention

[0005] The object of the present invention is to provide an outer conductor to solve the problem in the prior art that the front end of the outer conductor's spring claw easily collides with the plug end of the socket when the plug and the socket are plugged together, which easily causes the spring claw to be damaged; the object of the present invention is also to provide a coaxial connector to solve the above problem.

[0006] To achieve the above-mentioned purpose, the technical solution of the outer conductor of the present invention is:

[0007] The outer conductor has the plug-in end of the outer conductor as the front end, and includes a ring sleeve and a spring claw arranged at the front end of the ring sleeve. A plurality of spring claws are arranged at intervals along the circumference of the ring sleeve, and the spring claws have a spring claw convex portion protruding outward. The outer conductor also includes a protective ring in front of the spring claw, and a connecting arm is provided between two adjacent spring claws. The front ends of all connecting arms are connected to the protective ring; the outer diameter of the protective ring is greater than the diameter of the circle where the front ends of each spring claw are located, and the outer diameter of the protective ring is smaller than the diameter of the circle where the outermost side of each spring claw convex portion is located.

[0008] The beneficial effect is that, because the outer diameter of the protective ring is larger than the diameter of the circle around the front ends of the spring claws, when the outer conductor and the matching outer conductor are plugged together, the protective ring protects the front ends of the spring claws, preventing the front ends of the spring claws from contacting the matching connector, thereby ensuring that the spring claws are not damaged. Furthermore, the outer diameter of the protective ring is smaller than the diameter of the circle around the outermost edges of the protruding portions of the spring claws, allowing the protective ring to smoothly enter the matching outer conductor while ensuring interference contact between the protruding portions of the spring claws and the inner wall of the matching outer conductor.

[0009] As a further improvement, the connecting arm has a connecting arm protrusion protruding outward, the connecting arm protrusion is used to make transitional contact with the inner wall of the adapted outer conductor, and the distance between the connecting arm protrusion and the protective ring is smaller than the distance between the claw protrusion and the protective ring.

[0010] The beneficial effect is that when plugging in, all the protrusions of the connecting arms first make transitional contact with the inner wall of the adapting outer conductor, so as to ensure the coaxiality of the outer conductor and the adapting outer conductor before each spring claw enters the adapting outer conductor, thereby ensuring that each spring claw is subjected to uniform force after entering the adapting outer conductor, thereby improving the service life of the outer conductor.

[0011] As a further improvement, the outer conductor is provided with a deformation gap extending from the rear end of one of the connecting arms to the front end of the protective ring.

[0012] The beneficial effect is that, even if there is a processing error in the protrusion of the connecting arm, each protrusion of the connecting arm can shrink inward through the deformation gap to smoothly enter the adaptive outer conductor.

[0013] As a further improvement, the distance between the protrusion of the connecting arm and the protective ring is 0.1 to 0.3 mm smaller than the distance between the protrusion of the spring claw and the protective ring.

[0014] The beneficial effect is that such a design ensures that the connecting arm protrusion and the elastic claw protrusion are misaligned in the axial direction of the outer conductor, so that the misalignment size between the connecting arm protrusion and the elastic claw protrusion is not large, which is conducive to the miniaturization design of the outer conductor 11.

[0015] As a further improvement, the outer diameter of the protective ring is smaller than or equal to the outer diameter of the ring sleeve.

[0016] The beneficial effect is that such a design facilitates the protective ring to enter the adapted outer conductor while the protective ring protects the front end of the spring claw.

[0017] To achieve the above objectives, the technical solution of the coaxial connector of the present invention is:

[0018] A coaxial connector includes an outer conductor, an insulator, and an inner conductor coaxially sheathed together, with the mating end of the outer conductor as the front end. The outer conductor includes a ring sleeve and a spring claw arranged at the front end of the ring sleeve. A plurality of spring claws are arranged at intervals along the circumference of the ring sleeve, and the spring claws have a spring claw convex portion protruding outward. The outer conductor also includes a protective ring located in front of the spring claws. Connecting arms are provided between adjacent two spring claws, and the front ends of all connecting arms are connected to the protective ring. The outer diameter of the protective ring is larger than the diameter of the circle on which the front ends of each spring claw are located, and the outer diameter of the protective ring is smaller than the diameter of the circle on which the outermost side of each spring claw convex portion is located.

[0019] The advantageous effect is that, because the outer diameter of the protective ring is larger than the diameter of the circle around the front ends of the spring claws, when the coaxial connector and the adapter connector are mated, the protective ring protects the front ends of the spring claws, thereby preventing the front ends of the spring claws from contacting the adapter connector, thereby ensuring that the spring claws are not damaged. Furthermore, the outer diameter of the protective ring is smaller than the diameter of the circle around the outermost portions of the protruding portions of the spring claws, enabling the protective ring to smoothly enter the adapter outer conductor while ensuring interference contact between the protruding portions of the spring claws and the inner wall of the adapter outer conductor.

[0020] As a further improvement, the connecting arm has a connecting arm protrusion protruding outward, the connecting arm protrusion is used to make transitional contact with the inner wall of the adapted outer conductor, and the distance between the connecting arm protrusion and the protective ring is smaller than the distance between the claw protrusion and the protective ring.

[0021] The beneficial effect is that when plugging in, all the protrusions of the connecting arms first make transitional contact with the inner wall of the adapting outer conductor, so as to ensure the coaxiality of the outer conductor and the adapting outer conductor before each spring claw enters the adapting outer conductor, thereby ensuring that each spring claw is subjected to uniform force after entering the adapting outer conductor, thereby improving the service life of the outer conductor.

[0022] As a further improvement, the outer conductor is provided with a deformation gap extending from the rear end of one of the connecting arms to the front end of the protective ring.

[0023] The beneficial effect is that, even if there is a processing error in the protrusion of the connecting arm, each protrusion of the connecting arm can shrink inward through the deformation gap to smoothly enter the adaptive outer conductor.

[0024] As a further improvement, the distance between the protrusion of the connecting arm and the protective ring is 0.1 to 0.3 mm smaller than the distance between the protrusion of the spring claw and the protective ring.

[0025] The beneficial effect is that such a design ensures that the connecting arm protrusion and the elastic claw protrusion are misaligned in the axial direction of the outer conductor, so that the misalignment size between the connecting arm protrusion and the elastic claw protrusion is not large, which is conducive to the miniaturization design of the outer conductor 11.

[0026] As a further improvement, the outer diameter of the protective ring is smaller than or equal to the outer diameter of the ring sleeve.

[0027] The beneficial effect is that such a design facilitates the protective ring to enter the adapted outer conductor while the protective ring protects the front end of the spring claw.

[0028] As a further improvement, a stepped hole is provided in the insulator, which includes a large hole section and a small hole section located at the front end of the large hole section, and the inner conductor is located in the large hole section; the inner conductor has a socket for inserting the pin of the adapter connector, and the inner diameter of the front end of the socket is larger than the inner diameter of the small hole section.

[0029] The beneficial effect is that: such a design guides the insertion pin through the small hole section, ensuring that the insertion pin can be accurately inserted into the jack.

[0030] As a further improvement, a first slot is provided on the outer wall of the insulator, and an outer conductor barb is provided on the outer conductor, and the outer conductor barb is used to cooperate with the first slot to fix the outer conductor and the insulator together; a second slot is provided on the inner wall of the insulator, and an inner conductor barb is provided on the inner conductor, and the inner conductor barb is used to cooperate with the second slot to fix the inner conductor and the insulator together.

[0031] The beneficial effect is that the cooperation between the clamping groove and the barb not only makes it easier to fix the outer conductor and the insulator, as well as the inner conductor and the insulator, but also provides better stability after fixation.

[0032] As a further improvement, the first clamping groove is an annular groove, the second clamping groove is a rectangular groove connected to the first clamping groove, and the width of the rectangular groove is greater than the width of the inner conductor barb.

[0033] The beneficial effects are: such a design ensures that the inner conductor barb can enter the rectangular groove even if there is a processing error; moreover, the inner conductor barb is in a resilient state in the rectangular groove, and the holding force is stable.

[0034] As a further improvement, the rear end of the outer conductor is provided with a soldering pad folded outward, and at least two soldering pads are arranged at intervals along the circumference of the outer conductor. The rear end of the insulator has an insulating protrusion protruding outward, and the insulating protrusion is clamped between two of the soldering pads. The insulating protrusion has a positioning groove with an opening facing downward and extending radially along the outer conductor; the rear end of the inner conductor is provided with a connecting plate for connecting to a circuit board, and the connecting plate is positioned and installed in the positioning groove.

[0035] The beneficial effect is that by clamping the insulating protrusion between two of the welding pads and positioning the connecting plate in the positioning groove of the insulating protrusion, relative rotation between the outer conductor, the insulator and the inner conductor will not occur.

[0047] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0048] Embodiment 1 of the coaxial connector of the present invention:

[0049] like Figures 1 to 7 As shown, the coaxial connector includes an outer conductor 11, an insulator 12, and an inner conductor 13 coaxially sleeved together. The outer conductor 11 has a front end facing the plug end. The outer conductor 11 includes a ring 111, spring claws 113 at the front end of the ring 111, and a protective ring 115 in front of the spring claws 113. Three spring claws 113 are arranged at intervals along the circumference of the ring 111. The spring claws 113 have outwardly protruding spring claw protrusions 114, which are configured to achieve interference contact with the inner wall of the outer conductor 15. A connecting arm 117 is provided between any two adjacent spring claws 113, that is, three connecting arms 117 are provided, and the front ends of all connecting arms 117 are connected to the protective ring 115.

[0050] In this embodiment, the outer diameter of the protection ring 115 is larger than the diameter of the circle where the front end of each claw 113 is located, and the outer diameter of the protection ring 115 is smaller than the diameter of the circle where the outermost side of each claw protrusion 114 is located. Figure 6 and Figure 7 As shown, when the outer conductor 11 and the matching outer conductor 15 are mated, the protective ring 115 protects the front end of the spring claw 113 to prevent the front end of the spring claw 113 from contacting the matching outer conductor 15, thereby ensuring that the spring claw 113 is not damaged. It should be noted that after the outer conductor 11 and the matching outer conductor 15 are mated, the inner side of the front end of the spring claw 113 does not contact the insulator 12.

[0051] like Figure 3As shown, the connecting arm 117 has a connecting arm protrusion 116 protruding outward, and the connecting arm protrusion 116 is used to make transitional contact with the inner wall of the adapting outer conductor 15, that is, the diameter of the circle on the outermost side of each connecting arm protrusion 116 is larger than the outer diameter of the protective ring 115, and the diameter of the circle on the outermost side of each connecting arm protrusion 116 is smaller than the diameter of the circle on the outermost side of each claw protrusion 114.

[0052] In this embodiment, the distance between the connecting arm protrusion 116 and the protective ring 115 is smaller than the distance between the claw protrusion 114 and the protective ring 115. Figure 7 As shown, during insertion, all the connecting arm protrusions 116 first make transitional contact with the inner wall of the adapting outer conductor 15 to ensure the coaxiality of the outer conductor 11 and the adapting outer conductor 15 before each spring claw 113 enters the adapting outer conductor 15, thereby ensuring that each spring claw 113 is subjected to uniform force after entering the adapting outer conductor 15, thereby improving the service life of the outer conductor 11.

[0053] Preferably, the distance between the connecting arm protrusion 116 and the protective ring 115 is 0.1 to 0.3 mm smaller than the distance between the spring claw protrusion 114 and the protective ring 115. This design ensures that the connecting arm protrusion 116 and the spring claw protrusion 114 are axially misaligned with each other on the outer conductor 11, while minimizing the misalignment between the connecting arm protrusion 116 and the spring claw protrusion 114, thereby facilitating a miniaturized design of the outer conductor 11.

[0054] like Figure 1 As shown, the outer conductor 11 is provided with a deformation gap 14, which extends from the rear end of one of the connecting arms 117 to the front end of the protective ring 115. This design ensures that even if there are manufacturing errors in the connecting arm protrusions 116, each connecting arm protrusion 116 can retract inward through the deformation gap 14 to smoothly fit into the outer conductor 15.

[0055] In this embodiment, the outer diameter of the protective ring 115 is smaller than the outer diameter of the ring sleeve 111. This design facilitates the protective ring 115 to enter the adapting outer conductor 15 while protecting the front end of the spring claw 113.

[0056] like Figure 4 As shown, a first chamfer 119 is provided at the front end of the protection ring 115 , which further facilitates the protection ring 115 to enter the adapted outer conductor 15 .

[0057] like Figures 3 to 5 As shown, a stepped hole is provided in the insulator 12. The stepped hole comprises a large hole section 124 and a small hole section 125 located at the front end of the large hole section 124. The inner conductor 13 is located within the large hole section 124. The inner conductor 13 has a socket 133 for inserting a pin of the adapter connector. The inner diameter of the front end of the socket 133 is larger than the inner diameter of the small hole section 125. This design guides the pin through the small hole section 125, ensuring that the pin can be accurately inserted into the socket 133.

[0058] In this embodiment, a second chamfer 126 is provided at the front end of the small hole section 125 . This design facilitates the insertion of the pin into the small hole section 125 .

[0059] In this embodiment, a first retaining groove is provided on the outer wall of the insulator 12. Preferably, the first retaining groove is an annular groove 121. The outer conductor 11 is provided with an outer conductor barb 112. Three outer conductor barbs 112 are arranged at intervals along the circumference of the outer conductor 11. The outer conductor barbs 112 cooperate with the annular groove 121 to secure the outer conductor 11 to the insulator 12. A second retaining groove is provided on the inner wall of the insulator 12. Preferably, the second retaining groove is a rectangular groove 122. The inner conductor 13 is provided with an inner conductor barb 131. Two inner conductor barbs 131 are arranged at intervals along the circumference of the inner conductor 13. The inner conductor barbs 131 cooperate with the rectangular groove 122 to secure the inner conductor 13 to the insulator 12. The annular groove 121 is connected to the rectangular groove 122.

[0060] In this embodiment, the width of the rectangular groove 122 is greater than the width of the inner conductor barb 131. This design ensures that the inner conductor barb 131 can enter the rectangular groove 122 even if there is a processing error; moreover, the inner conductor barb 131 is in a pop-up state in the rectangular groove 122, and the holding force is stable.

[0061] In this embodiment, the rear end of the outer conductor 11 is provided with a soldering pad 118 that is folded outward 90 degrees. The soldering pad 118 is used for soldering to the circuit board. Four soldering pads 118 are arranged at intervals along the circumference of the outer conductor 11. The rear end of the insulator 12 has an outwardly protruding insulating protrusion 123, which is clamped between two of the soldering pads 118. Figure 1 and Figure 2 As shown, the insulating protrusion 123 has a positioning groove 127 with an opening facing downward and extending radially along the outer conductor 11 . The rear end of the inner conductor 13 is provided with a connecting plate 132 for connecting to a circuit board. The connecting plate 132 is positioned and installed in the positioning groove 127 .

[0062] In this embodiment, the outer conductor 11 is integrally formed by using common sheet metal processing, machining or casting techniques in the industry.

[0063] Embodiment 2 of the coaxial connector of the present invention:

[0064] This embodiment differs from Example 1 in that, in Example 1, the connecting arm has an outwardly protruding connecting arm protrusion configured to make transitional contact with the inner wall of the matching outer conductor. In this embodiment, the connecting arm does not have a connecting arm protrusion, but instead increases the outer diameter of the protective ring so that it is slightly smaller than the inner diameter of the matching outer conductor.

[0065] Embodiment 3 of the coaxial connector of the present invention:

[0066] The difference between this embodiment and embodiment 1 is that, whereas in embodiment 1, a deformation gap is provided on the outer conductor extending from the rear end of one of the connecting arms to the front end of the protective ring, this embodiment does not provide a deformation gap. Instead, a slight deformation of the connecting arm is utilized to cause the convex portion of the connecting arm to retract inward.

[0067] Embodiment 4 of the coaxial connector of the present invention:

[0068] The difference between this embodiment and embodiment 1 is that in embodiment 1, the outer diameter of the protective ring is smaller than the outer diameter of the ring sleeve. In this embodiment, the outer diameter of the protective ring is equal to the outer diameter of the ring sleeve. In other embodiments, the outer diameter of the protective ring is slightly larger than the outer diameter of the ring sleeve.

[0069] Embodiment 5 of the coaxial connector of the present invention:

[0070] This embodiment differs from Example 1 in that, in Example 1, a stepped hole is provided within the insulator, comprising a large hole section and a small hole section located at the front end of the large hole section, with the inner conductor located within the large hole section. In this embodiment, a through hole with a uniform diameter is provided within the insulator, with the inner conductor located within the through hole.

[0071] Embodiment 6 of the coaxial connector of the present invention:

[0072] This embodiment differs from Example 1 in that, in Example 1, the outer conductor barb cooperates with the first retaining groove to secure the outer conductor and the insulator together, and the inner conductor barb cooperates with the second retaining groove to secure the inner conductor and the insulator together. In this embodiment, barbs and retaining grooves are not provided; the outer conductor and the insulator are interference-fitted together, and the inner conductor and the insulator are interference-fitted together. To ensure stability, glue may be applied to the contact surfaces of the outer conductor and the insulator, as well as the contact surfaces of the inner conductor and the insulator.

[0073] The outer conductor of the embodiment of the present invention has the same structure as the outer conductor described in any one of the embodiments 1 to 4 of the coaxial connector, and will not be described in detail here.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall be included in the scope of protection of the present invention.
