Description

Technical Field

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

[0002] When realizing radio frequency signal transmission between two circuit boards, a traditional SMP three-piece structure is usually adopted. As Figure 1 shown, two sockets 200 are respectively welded on two circuit boards 100 to be connected, and a floating connection is realized by an adapter 300 in the middle. This structure has been widely used in the communication field. However, with the increasing requirements for miniaturization, easy maintenance, and low cost of equipment, this connection method can no longer meet the usage requirements due to its large volume and troublesome installation operation.

[0003] Currently, there are also connectors used to realize inter-board connection. For example, the connector disclosed in the Chinese utility model patent document with the authorization announcement number CN208608422U includes an outer conductor and a center conductor arranged in the outer conductor through an inner insulator. The outer conductor includes a first outer conductor and a second outer conductor that can be slidably assembled together. A first elastic element for applying an axial thrust to the first outer conductor is provided between the first outer conductor and the second outer conductor. The floating conductive contact between two electronic components is realized by the axial thrust applied to the first outer conductor by the first elastic element.

[0004] When assembling the connector, the two parts of the outer conductor need to be assembled to realize the sliding connection between the two outer conductors, and the first outer conductor needs to be in contact with the first elastic element to realize the floating conductive contact between the outer conductor and the corresponding electronic component under the driving action of the first elastic element. The outer conductor with this split structure increases the assembly process of the outer conductor, resulting in a more cumbersome and inconvenient assembly process for the entire connector. Summary of the Invention

[0005] The purpose of the present invention is to provide an outer conductor for a coaxial connector to solve the technical problem of inconvenient assembly caused by the split structure of the outer conductor in the prior art; correspondingly, the purpose of the present invention is also to provide a coaxial connector to solve the technical problem that the coaxial connector is not easy to assemble due to the split structure of the outer conductor of the coaxial connector in the prior art.

[0006] To achieve the above object, the technical solution of the outer conductor of the coaxial connector of the present invention is as follows: The outer conductor of the coaxial connector includes a jacket body formed by rolling; one end of the jacket body is integrally provided with contact elastic members, and a plurality of the contact elastic members are circumferentially distributed along the jacket body. Each contact elastic member extends obliquely away from the jacket body along the axial direction of the jacket body, and the contact elastic members are used for floating adjustment when crimping and conducting electricity with a target connector; the other end of the jacket body is integrally provided with an outer conductor connection portion, and the outer conductor connection portion is used for electrically and fixedly connecting with a fixed connector.

[0007] The beneficial effects of the present invention are as follows: The contact elastic members and the outer conductor connection portion are integrally provided at both ends of the jacket body respectively, and are used for electrically cooperating with the target connector and the fixed connector respectively, and realizing the floating adjustment of electricity conduction between the two connectors. This outer conductor is an integral structure. When it is applied to a connector, the entire outer conductor can be directly fixedly assembled with the inner insulator and the center conductor, so as to reduce the assembly process of the connector and lower the assembly cost.

[0008] Further, a stop projection is provided on the jacket body, which is used for top-pressing and cooperating with the inner insulator fittingly inserted into the jacket body, so as to fix the jacket body on the inner insulator. The jacket body is top-pressed and cooperated with the inner insulator to fix the jacket body on the inner insulator, increasing the stability of the assembly structure of the coaxial connector.

[0009] Further, the stop projection is an inclined elastic piece arranged on the inner wall surface of the jacket body protruding inward from the jacket body, and is used for top-pressing and blocking cooperation with a positioning groove provided on the inner insulator, so as to determine the assembly position of the inner insulator and the jacket body. The inclined elastic piece and the positioning groove are top-pressed and blocked to cooperate, so that the outer conductor and the inner insulator have a better anti-disconnection effect, which is convenient to implement in the present invention.

[0010] Further, the outer conductor connection portion is a bent connecting arm, and the bent connecting arm includes a transverse arm section integrally and transitionally connected to the corresponding end of the jacket body and a vertical arm section transitionally connected to the transverse arm section. The vertical arm section extends along the axial direction of the jacket body for electrically and fixedly assembling with the fixed connector. The transverse arm section provided on the bent connecting arm can be used to make the vertical arm section correspondingly arranged with the corresponding connection position on the fixed connector, and by using the extended arrangement of the transverse arm section, the outer diameter size of the jacket body part can be reduced on the basis of ensuring the normal installation and connection of the outer conductor, reducing the size of the entire outer conductor and saving the material cost.

[0011] Further, the transverse arm section is a support arm section, which is used for supporting a support sleeve sleeved on the jacket body. The outer conductor with this structural setting can increase the stability of the assembly structure of the coaxial connector, realize the positioning assembly of the support sleeve, and prevent the support sleeve from detaching from the outer conductor.

[0012] Furthermore, the outer casing is provided with a support top protrusion protruding outward from the outer wall of the outer casing, which is used to cooperate with the support sleeve top support assembled outside the outer casing. The support top protrusion cooperates with the support sleeve top support to strengthen the fixed connection effect between the outer conductor and the support sleeve, and prevent the support sleeve from detaching from the outer conductor.

[0013] Furthermore, the top supporting protrusion is a top supporting spring sheet. The top supporting protrusion in the form of a top supporting spring sheet structure has a simple structure and is easy to process and manufacture.

[0014] Furthermore, the contact elastic member is a contact spring, and the contact spring is folded outward or inward relative to the outer shell in the radial direction of the outer shell. The contact spring has a simple structure and is easy to process, and the contact spring is folded outward or inward relative to the outer shell in the radial direction of the outer shell, which is convenient for the contact spring to be bent and formed.

[0015] Furthermore, the outer conductor is provided with a dovetail groove and a dovetail protrusion that cooperate with each other. After the outer conductor is supported by the inner insulator, the dovetail groove and the dovetail protrusion cooperate with each other to connect the outer conductor at the rolled joint to prevent the outer conductor from being stretched apart from the rolled joint.

[0016] To achieve the above-mentioned purpose, the technical solution of the coaxial connector of the present invention is: the coaxial connector includes a center conductor, an inner insulator and an outer conductor, the center conductor is fixedly inserted in the inner insulator, the center conductor is an elastic floating structure, which is used for floating adjustment when the center conductor is crimped and conductive with the target connector, and the outer conductor includes a rolled outer shell; one end of the outer shell is integrally provided with a contact elastic member, and a plurality of the contact elastic members are evenly distributed along the circumference of the outer shell, and each contact elastic member extends obliquely away from the outer shell along the axial direction of the outer shell, and the contact elastic member is used for floating adjustment when crimped and conductive with the target connector; the other end of the outer shell is integrally provided with an outer conductor fixing portion, and the outer conductor fixing portion is used for conductive and fixed connection with the fixed connector, and the inner insulator is fitted and inserted in the outer shell.

[0017] The beneficial effects of the present invention are as follows: the coaxial connector includes a center conductor and an outer conductor, wherein the outer conductor includes an integrally formed contact elastic member and an outer conductor fixing portion, which can realize conductive floating adjustment between the two connectors. Since the outer conductor is an integrally formed structure, the inner insulator is fitted and inserted into the outer sleeve, which effectively ensures the supporting strength of the outer conductor; and when assembling the coaxial connector, the problem of more assembly processes brought about by the existing split outer conductor can be effectively avoided, thereby reducing the assembly processes of the entire coaxial connector and reducing the assembly cost.

[0018] Further, the coaxial connector further includes a support member assembled outside the outer sleeve body, and the support member is used to support the target connector. The provision of the support member can prevent the contact elastic member from being broken during the up-and-down floating process of the target connector, thereby affecting the signal transmission between the target connector and the fixed connector. Moreover, the support member can fixedly press-fit the outer conductor on the outer peripheral surface of the inner insulator, which helps to increase the structural stability of the entire coaxial connector.

[0019] Further, the support member is a support sleeve. The support member in the form of a support sleeve has a simple structure and is easy to implement, and can preferably press-fit and fix the entire outer conductor on the inner insulator.

[0020] Further, the outer sleeve body is provided with a support protrusion protruding outward from the outer wall surface of the outer sleeve body, and the support protrusion is in top support cooperation with the support sleeve. The top support cooperation between the support protrusion and the support sleeve can strengthen the fixed connection effect between the outer conductor and the support sleeve and prevent the support sleeve from detaching from the outer conductor.

[0021] Further, the support protrusion is a support elastic piece. The support protrusion in the form of a support elastic piece has a simple structure and is easy to process and manufacture.

[0022] Further, the support sleeve is composed of two semi-circular structures that are snap-fitted together. The support sleeve with this structural form has a simple structure, is convenient for operation and assembly, and is easy to implement in the present invention.

[0023] Further, the outer conductor fixing portion is a bent connecting arm. The bent connecting arm includes a transverse arm section integrally and transitionally connected to the corresponding end of the outer sleeve body and a vertical arm section transitionally connected to the transverse arm section. The vertical arm section extends along the axial direction of the outer sleeve body, and the vertical arm section is used for electrically fixedly assembling with the fixed connector. The support sleeve is supported and placed on the transverse arm section. The transverse arm section provided on the bent connecting arm can be used to make the vertical arm section correspond to the corresponding connection position on the fixed connector. Moreover, by using the extended arrangement of the transverse arm section, the outer diameter dimension of the outer sleeve body part can be reduced on the basis of ensuring the normal installation and connection of the outer conductor, the size of the entire outer conductor can be reduced, the material cost can be saved, and the support sleeve is supported and placed on the transverse arm section, so that the positioning and assembly of the support sleeve can be realized and the support sleeve can be prevented from detaching from the outer conductor.

[0024] Further, the outer sleeve body is provided with a stop protrusion, which is in top pressure cooperation with the inner insulator to fix the outer sleeve body on the inner insulator. The outer sleeve body is in top pressure cooperation with the inner insulator to fix the outer sleeve body on the inner insulator, increasing the stability of the assembly structure of the coaxial connector.

[0025] Furthermore, the stop protrusion is an inclined spring piece arranged on the outer shell and protruding inwardly from the inner wall surface of the outer cylinder, and the inclined spring piece cooperates with the positioning groove provided on the inner insulator to press and stop, so as to determine the assembly position of the inner insulator and the outer shell. The inclined spring piece and the positioning groove press and stop cooperate, so that the outer conductor and the inner insulator have a better anti-slip effect, which is convenient to implement in the present invention.

[0026] Furthermore, the contact elastic member is a contact spring, and the contact spring is folded outward or inward relative to the outer shell in the radial direction of the outer shell. The contact spring has a simple structure and is easy to process, and the contact spring is folded outward or inward relative to the outer shell in the radial direction of the outer shell, which is convenient for the contact spring to be bent and formed.

[0027] Furthermore, the outer conductor is provided with a dovetail groove and a dovetail protrusion that cooperate with each other. After the outer conductor is supported by the inner insulator, the dovetail groove and the dovetail protrusion cooperate with each other to connect the outer conductor at the rolled joint to prevent the outer conductor from being stretched apart from the rolled joint.

DETAILED DESCRIPTION

[0036] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0037] Combination Figure 1 Explain the overall technical concept of the present invention, Figure 1 In the embodiment, two sockets 200 are respectively fixedly connected to two circuit boards 100, and then an adapter 300 is used to achieve the transfer to meet the floating tolerance. In order to solve the problems of large volume and complex structure of the three-piece structure, the coaxial connector provided by the present invention can be used. For the convenience of explanation, as shown in FIG. Figure 3 As shown, one of the two circuit boards is defined as a fixed plate 4, and the other is defined as a crimping plate 5. When the two circuit boards are connected using a coaxial connector, the fixed plate 4 is fixedly connected to the coaxial connector, while the crimping plate 5 is conductively connected to the coaxial connector. By utilizing the elastic floating center conductor 3 and the contact spring 13 provided on the outer conductor 1 in the coaxial connector, the deviation adjustment of the crimping plate 5 and the fixed plate 4 can be satisfied while ensuring the conductive connection between the crimping plate 5 and the coaxial connector.

[0038] It should be noted that the coaxial connector in the present invention is not only used between two parallel circuit boards, but also can be used between two filters, or between two parallel structures to achieve radio frequency signal transmission between the parallel structures.

[0039] The coaxial connector and its outer conductor are introduced in detail below.

[0040] Specific implementation of the coaxial connector provided by the present invention:

[0041] like Figure 2 The figure shows a specific structure of a coaxial connector in an embodiment, which includes an outer conductor 1, an inner insulator 2 and a center conductor 3. During assembly, the center conductor 3 is fixedly inserted into the inner insulator 2, and then the inner insulator 2 is assembled into the outer conductor 1 to achieve an insulation interval between the center conductor 3 and the outer conductor 1.

[0042] In this embodiment, as Figure 2 and Figure 3 shown, one end of the center conductor 3 is the center conductor fixed part 31, and the other end is the center conductor floating part 32. The center conductor fixed part 31 is used for fixedly connecting with the corresponding fixing plate 4, while the center conductor floating part 32 is used for voltage-conductive crimping with the corresponding target connector such as the crimping plate 5. The center conductor floating part 32 can elastically float relative to the center conductor fixed part 31, so that the center conductor 3 is an elastic floating structure as a whole. When the crimping plate 5 floats downward, the center conductor floating part 32 will elastically retract, and when the crimping plate 5 floats upward, the center conductor floating part 32 pops out. The center conductor 3 here is a commercially available product, and will not be elaborated too much here. It should be noted that such a center conductor can adopt the center conductor structure disclosed in the Chinese utility model patent with the authorization announcement number CN208608422U, or the center conductor structure disclosed in the Chinese invention patent application with the application publication number CN109038004A, as long as the center conductor is an elastic floating structure.

[0043] In this embodiment, as Figure 2 shown, the inner insulator 2 is a hollow cylindrical structure coaxially and conformally sleeved outside the center conductor 3. The inner insulator 2 is made of a non-metallic material and is in press-fit with the center conductor 3, so as to realize the fixed assembly of the center conductor 3 and the inner insulator 2.

[0044] In this embodiment, as Figure 2 and Figure 4 shown, the outer conductor 1 is an overall ring sleeve structure to realize the conforming insertion with the inner insulator 2. The outer conductor 1 includes an outer sleeve body 11. One end of the outer sleeve body 11 in the axial direction is integrally provided with an outer conductor fixed part for electrically connecting with the fixing plate 4. Specifically in use, it can be fixed by connection methods such as welding, surface mounting, and press-fitting.

[0045] The other end of the outer sleeve body 11 in the axial direction is integrally provided with a contact elastic member, which is used for top-pressure cooperation with the crimping plate 5 to realize the electrical connection between the fixing plate 4 and the crimping plate 5. In this embodiment, the contact elastic member is specifically a contact spring piece 13. A plurality of contact spring pieces 13 are arranged, and are evenly arranged along the circumferential direction of the outer sleeve body 11. Any two adjacent contact spring pieces 13 are relatively independently arranged, and each contact spring piece 13 is in top-pressure cooperation with the crimping plate 5, which can make the crimping plate 5 float and adjust, and enable the two circuit boards to deflect at multiple angles without affecting the signal transmission between the two circuit boards. In other embodiments, the contact elastic member can also be a contact spring claw or other elastic members integrally formed with the outer sleeve body in the prior art.

[0046] In this embodiment, the contact elastic pieces 13 are all turned outward relative to the outer sleeve 11 as a whole, so that the contact elastic pieces 13 extend obliquely away from the outer conductor 1 along the axial direction of the outer sleeve 11. In order to avoid damaging the crimping plate 5 during crimping, an arc-shaped folding structure 131 is usually provided at the contact part with the crimping plate 5. In other embodiments, the contact elastic pieces can also be turned inward relative to the outer sleeve as a whole, so that the contact elastic pieces extend obliquely away from the outer conductor along the axial direction of the outer sleeve, which is convenient for performing an integral bending operation on all the contact elastic pieces after the contact elastic pieces are stamped and formed. Of course, in other embodiments, the contact elastic pieces can also be turned inward for a part and outward for another part relative to the outer sleeve. For this setting of the contact elastic pieces, at least two bending processes are required.

[0047] In this embodiment, as Figure 2 and Figure 4 shown, a stop protrusion protruding inward from the inner wall surface of the outer sleeve 11 is provided on the outer sleeve 11. The stop protrusion is specifically an inclined elastic piece 111 provided on the outer sleeve 11 and protruding from the inner wall surface of the outer sleeve 11. The inclined elastic piece 111 is inclined toward the fixing plate 4. Correspondingly, a positioning groove 21 extending circumferentially is provided on the inner insulator 2. The inner insulator 2 is made of polytetrafluoroethylene. During the process of inserting the inner insulator 2 into the outer sleeve 11 from one axial end, the inclined elastic piece 111 and the positioning groove 21 are pressed against and stopped to determine the assembly position of the inner insulator 2 and the outer sleeve 11, so that the anti-disengagement effect between the outer sleeve 11 and the inner insulator 2 is better. In other embodiments, the inner insulator can also be made of other non-metallic materials such as rubber and ceramics.

[0048] In other embodiments, the stop protrusion can also be a circular protrusion provided on the outer sleeve, and the circular protrusion is pressed against and stopped with the positioning groove to determine the assembly position of the inner insulator and the outer sleeve; or in other embodiments, the inner insulator may not be provided with a positioning groove, and the inner insulator is made of polytetrafluoroethylene, so that the inner insulator deforms under external force extrusion, and the inclined elastic piece pierces into the inner insulator to realize the relative fixation of the outer conductor and the inner insulator, and increase the stability of the coaxial connector assembly structure; or in other embodiments, the positioning groove can also be a plurality of grooves arranged at intervals along the axial direction to cooperate with the stop protrusion through the positioning groove to realize the anti-rotation effect in the circumferential direction and the anti-disengagement effect in the axial direction between the outer sleeve and the inner insulator.

[0049] In this embodiment, two inclined elastic pieces 111 are arranged at intervals along the circumferential direction on the outer sleeve 11, which can make the change of the fitting diameter between the outer conductor 1 and the inner insulator 2 relatively gentle, which is beneficial to assembly, and more importantly, to avoid impedance mutation caused by sudden change of the diameter of the inner insulator 2, which is beneficial to signal transmission between two circuit boards. In other embodiments, the number of the inclined elastic pieces can also be one, three, four or more than five to achieve a better limiting effect between the outer conductor and the inner insulator.

[0050] As shown Figure 2 in the figure, the coaxial connector further includes a support member sleeved outside the outer sleeve 11, and the support member can be used to support the crimping plate 5 to prevent the contact elastic piece 13 from being broken during the up-and-down floating of the crimping plate 5. In this embodiment, the support member is a support sleeve 6. The support sleeve 6 is fitted and sleeved outside the outer sleeve 11 and presses the outer sleeve 11 on the inner insulator 2. The support sleeve 6 cooperates with the inner insulator 2 to press and fix the outer conductor 1 outside the center conductor 3, which helps to strengthen the strength of the outer conductor 1 and increase the structural stability of the coaxial connector.

[0051] In this embodiment, as shown Figure 6 in the figure, the support sleeve 6 is formed by two semi-circular structures 61 that are snap-fitted together. Each semi-circular structure 61 is provided with a positioning block 611 and a positioning groove 612, and a buckle 613 and a clamping groove 614 that engages with the buckle 613 are also provided to snap the two semi-circular structures 61 together. In this embodiment, the support sleeve 6 is sleeved outside the outer sleeve 11, and the length of the support sleeve 6 in the axial direction is equal to the length of the outer sleeve 11 in the axial direction to fix the outer conductor 1 on the inner insulator 2.

[0052] In this embodiment, the support member is a support sleeve, and the support sleeve is formed by two semi-circular structures that are snap-fitted together. In other embodiments, the support member may further include support blocks that are circumferentially spaced and fitted outside the outer sleeve, and a clamping structure is provided outside the two support blocks to press and mount the two support blocks on the outer wall surface of the outer sleeve. The length of the two support blocks in the axial direction of the outer sleeve is equal to the axial length of the outer sleeve to achieve the support and limit of the crimping plate; or in other embodiments, the support sleeve includes two semi-circular structures, and the two semi-circular structures are hinged together at one snap-fitting position and snap-fitted through a buckle at the other snap-fitting position to press and mount the outer conductor on the inner insulator.

[0053] In this embodiment, to ensure the relative position of the support sleeve 6 and the outer sleeve 11 and prevent relative sliding between the two, as shown Figure 4 in the figure, a support projection protruding from the outer wall surface of the outer sleeve 11 is provided on the outer sleeve 11. The support projection is specifically a support elastic piece 112 provided on the outer sleeve. The support elastic piece 112 is inclined towards the fixing plate 4 so that after the support sleeve 6 is snap-fitted on the outer sleeve 11, the support elastic piece 112 abuts against the inner wall surface of the support sleeve 6 to strengthen the fixed connection effect between the outer sleeve 11 and the support sleeve 6 and prevent the support sleeve 6 from detaching from the outer sleeve 11.

[0054] In other embodiments, the support projection may also be a circular projection provided on the outer sleeve. After the support sleeve is snap-fitted on the outer sleeve, the circular projection abuts against the inner wall surface of the support sleeve to prevent the support sleeve from detaching from the outer conductor.

[0055] In this embodiment, two supporting elastic pieces 112 are evenly arranged at intervals along the circumferential direction of the outer sleeve 11. In other embodiments, there may be one supporting elastic piece, or three, four, or more than five supporting elastic pieces, and they are all evenly arranged at intervals along the circumferential direction of the outer sleeve, so as to press-fit the outer sleeve onto the inner insulator in the circumferential direction. In other embodiments, the supporting elastic pieces may also be arranged on the supporting sleeve and be inclined towards the outer sleeve, so that the supporting sleeve presses the outer sleeve onto the inner insulator. Or in other embodiments, when the outer diameter of the outer sleeve is equal to the inner diameter of the supporting sleeve and the precision is relatively high, the supporting elastic pieces may not be provided, and the supporting sleeve is assembled on the outer sleeve, and the cooperation between the supporting sleeve and the inner insulator can be realized to press the inner and outer conductors tightly between the two.

[0056] In this embodiment, the supporting sleeve 6 is a non-metallic sleeve. In other embodiments, the supporting sleeve may also be a metallic sleeve, so that the supporting sleeve can be made of various materials, making the supporting sleeve have better adaptability.

[0057] In this embodiment, the supporting sleeve 6 is mainly used to limit and support the crimping plate 5. In other embodiments, when the floating range of the crimping plate is small, the supporting sleeve may not be provided. After the outer sleeve and the inner insulator are inserted and assembled, the inner insulator expands the outer sleeve to press-fit the outer sleeve onto the inner insulator.

[0058] In this embodiment, as Figure 2 and Figure 4 shown, the outer conductor fixing part on the outer conductor 1 is a bent connecting arm 12. The bent connecting arm 12 includes a transverse arm section 121 connected to the outer sleeve 11 through an arc transition, and a vertical arm section 122 connected to the transverse arm section. The vertical arm section 122 extends along the axial direction of the outer sleeve 11, and the vertical arm section 122 is used for electrically fixed assembly with the fixing plate 4. In this embodiment, four vertical arm sections 122 are provided and are evenly arranged at intervals along the circumferential direction of the outer sleeve 11. The distance between adjacent vertical arm sections 122 depends on the distance between the corresponding connection positions on the fixing plate 4.

[0059] In this embodiment, the transverse arm section 121 extends radially outward along the outer sleeve 11. The supporting sleeve 6 is supported and placed on the transverse arm section 121 to cooperate with the transverse arm section 121 to block each other, which is used to limit the position of the supporting sleeve 6 in the axial direction of the sleeve body and increase the stability of the coaxial connector structure. Moreover, the setting of the transverse arm section 121 can reduce the outer diameter size of the part of the outer sleeve 11, reduce the size of the entire outer conductor 1 and the entire coaxial connector, and save material costs.

[0060] In this embodiment, before the bending connection arm is formed by rolling the outer conductor, the strip-shaped plate is first stamped by a stamping mechanism, and then the bent piece after stamping is bent and formed by a bending device. In other embodiments, in order to reduce the processing procedures of the outer conductor, without considering the material cost, the transverse arm section may not be provided, and the vertical arm section extending from the outer sleeve body can be directly conductively fixed to the fixing plate, and specifically, a welding connection method can be adopted; or in other embodiments, as Figure 7 shown, the vertical arm section may not be provided, and the transverse arm section 721 extending from the outer conductor 7 can be directly conductively connected to the fixing plate, and specifically, a surface mount connection method can be adopted.

[0061] In this embodiment, the thickness of the outer conductor is in the range of 0.1 mm to 0.2 mm. Of course, in other embodiments, depending on the size of the circuit board, the thickness of the outer conductor can also be greater than 0.2 mm. In this embodiment, during the production of the outer conductor, the strip-shaped plate is first stamped to form the general shapes of the contact elastic piece 13, the outer conductor fixing part, the supporting elastic piece 112, and the inclined elastic piece 111, and then the bending tool bends the contact elastic piece 13, the supporting elastic piece 112, and the inclined elastic piece 111 to the corresponding sides respectively, and uses the corresponding bending tool to bend the outer conductor fixing part into the shape of the bending connection arm 12, and finally the bent strip-shaped plate is rolled and formed.

[0062] As Figure 5 shown, a dovetail groove 114 and a dovetail-shaped protrusion 113 that cooperate with each other are provided at the rolling seam of the outer conductor 1. The dovetail-shaped protrusion 113 is inserted and matched with the dovetail groove 114, which can prevent the outer sleeve body 11 from being misaligned in the circumferential direction during the rolling process. Moreover, after the inner insulator 2 is inserted into the outer conductor 1, the insertion and matching part of the dovetail-shaped protrusion 113 and the dovetail groove 114 can be tightened, which helps the pressing fit between the outer conductor 1 and the inner insulator 2. In this embodiment, the rolled and formed outer conductor 1 needs to be heat-treated to make the outer conductor 1 have a higher hardness and avoid deformation during the assembly process of the outer conductor 1. The above integrally formed outer conductor 1 can be formed by a mold, which is beneficial to large-scale production, improves production efficiency, and reduces processing costs; moreover, it can effectively avoid the problem of more assembly procedures brought by the existing split-type outer conductor, reduce the assembly procedures of the entire coaxial connector, and reduce the assembly cost.

[0063] During the assembly of the coaxial connector in this embodiment, first, the center conductor 3 is installed at the center position of the inner insulator 2. Then, the inner insulator 2 is inserted into the outer sleeve 11 in a fitting manner, and the inclined elastic piece 111 on the outer sleeve 11 is in blocking cooperation with the positioning groove 21 on the inner insulator 2 to ensure that the inner insulator 2 and the outer conductor 1 are assembled in place. Finally, the support sleeve 6 is snap-fitted on the outside of the outer sleeve 11, so that the supporting elastic piece 112 on the outer sleeve 11 preferably abuts against the inner wall surface of the support sleeve 6, and the support sleeve 6 is supported on the transverse arm section 121 to ensure that the support sleeve 6 and the outer conductor 1 are assembled in place. This coaxial connector with an integrated outer conductor 1 can reduce the assembly of the outer conductor itself, reduce the assembly process of the entire coaxial connector, and lower the assembly cost.
