Description

Tool free coaxial cable connector

This invention relates to electrical devices, and more particularly to coaxial cable connectors.

Coaxial cable transmits radio frequency ("RF") signals between the transmitter and receiver for connecting televisions, cable boxes, DVD players, satellite receivers, modulators, and other electrical devices and electronic components ("electronics" The component is called). A typical coaxial cable includes an inner conductor, a layer of a soft dielectric insulator, a metal foil layer, a conductive metal sleeve or barrier layer, and a PVC chloride sleeve. The RF signal is transmitted via the inner conductor. The electrically conductive isolation layer provides grounding to prevent electromagnetic interference with the RF signal on the inner conductor.

Coaxial cables must be fitted with cable connectors for connection to electronic components. The connector usually has a connector body, a nut or a threaded fitting mounted on one end of the connector body, an aperture extending from the other end into the connector body for receiving the coaxial cable, and a An inner cylinder that is in electrical communication with the fitting within the bore. Typically, the connector is clipped to the prepared end of the coaxial cable and the connector is attached to the coaxial cable. However, the clamp sometimes crushes the coaxial cable, causing leakage, interference, or poor grounding. The number deteriorates. In addition, some connectors are too tight when mounted on the connector body, making the connector very difficult to lock to the cylinder of the electronic component; and some connector accessories are too loose when mounted on the connector body, so that the connector and the inside The electrical connection between the cylinders is interrupted as the fitting leaves the cylinder. Also, some connectors are loose and loose when mounted on the cable, causing the RF connection between the transmitter and the electrical device to be completely cut off. Furthermore, the connector usually has to be attached to the cable with special tools, and it is difficult to achieve good connection quality between the cable and the connection gas without special tools. How to quickly and securely mount the connector to the cable without special tools is really necessary.

A coaxial cable connector that can be easily mounted on a coaxial cable without special tools, comprising a body having a front end, a rear end, a longitudinal axis and an inner space. The connector also includes an inner cylinder disposed in the inner space and supporting the body. A threaded component is formed in the inner space of the body. The threaded assembly includes a first thread carried on the inner cylinder and a second thread on the upper limb of the body. The first and second threads bite and secure the cable that is rotated into the connector.

In the drawings, the same reference numerals are used to refer to the same elements. The toolless cable connector 10 shown in Figure 1 is constructed and arranged in accordance with the principles of the present invention and is mounted on a coaxial cable 11. An example of the illustrated connector 10 is an F connector for an RG6 coaxial cable. Please understand that the following description can be applied to other types of coaxial cable connectors and other types of cables. The illustrated cable 11 is a conventional cable, such as an RG6 coaxial cable, including an inner conductor 12 that extends beyond the connector 10 as shown in FIG. In the example shown in Figures 1-6B, the connector 10 includes a two-piece cylindrical assembly 13 comprised of a body 14 and a front cover 15. The connector 10 also includes a coaxially threaded fitting or screw that is rotatably mounted to the cover 15 of the body assembly 13. Cap 20. Both the cover 15 and the nut 20 are carried on the inner cylinder 21 shown in FIG. The longitudinal axis A passes through the connector 10, the body assembly 13, the nut 20, and the inner cylinder 21, and is rotationally symmetric with respect to the longitudinal axis A as shown in Figs. 2A and 2B.

3 and 6A are cross-sectional views of the connector 10 taken along line 6-6 of Fig. 1, with the body 14 of the body assembly 13 being a long cylindrical sleeve extending along the longitudinal axis A. The side wall 22 of the body 14 has opposing front and rear ends 23 and 24, and opposite inner and outer surfaces 25 and 26. The inner surface 25 constitutes and surrounds an inner space 30 for receiving the cable, and is shaped and sized to fit the coaxial cable 11 received therein. A three-quarter spiral 27 is formed adjacent the front end 23 of the inner surface 25, the spiral 27 starting with a ramp 28 that bulges from the smooth inner surface 25, and ends at a three-quarter spiral circumference around the inner surface. Form a vertical breakpoint. This thread 27 thus incompletely surrounds the circumferential portion of the body 14. The inner diameter B of the cable housing inner space 30 is determined by the inner surface 25. The front and rear ends 23 and 24 are open for access to the cable housing inner space 30. The outer surface 26 of the side wall 22 is formed as an axial groove 29 to enhance the grip of the body 14. The outer surface 26 determines the outer diameter C of the body 14.

Referring primarily to Figures 3 and 4, the front end 23 of the body 14 has a snap-fit engagement structure for engaging the cover 15. The main body 14 and the cover 15 can be separately packaged for transportation by the field technician to the coaxial cable 11. Therefore, the cover 15 is provided with a complementary structure complementary to the engaging structure of the main body 14, so that the cover 15 can be quickly put on site. Assembly onto the body 14. The engagement structure on the body 14 is a plurality of semi-annular barbs 31 separated from one another by block segments 32. The complementary engaging structure on the cover 15 is a plurality of rearwardly extending blocks 33 whose heads are enlarged to catch the barbs 32. Spaces 34 are spaced apart from each other between the blocks 33, and the gaps 34 are sized to receive the block segments 32. The block 33 is soft and can be slightly deformed outwardly from the axis A in the radial direction so as to be able to catch the barb 31 when the cover 15 is pressed onto the body 14. The block 33 engages the barb 31 to prevent the body 14 from being disengaged from the cover 15 in the axial direction. The block 32 is inserted into the gap 34 to prevent relative rotation of the body 14 and the cover 15. In this manner, once the block 33 catches the barb 31, the body assembly 13 becomes a single element without accidentally disengaging.

Still referring to Figures 3 and 4, the cover 15 is approximately cylindrical and has a front end 35 and a back-to-back end 36, and a stepped side wall 40 extending therebetween. The side wall 40 is adjacent to the front end 35 as a front portion 41 and adjacent to the rear end 36 as a rear portion 42. The diameter of the rear portion 42 is equal to the diameter C of the body 14, and the diameter D of the front portion 41 is smaller than the diameter C but larger than the diameter B of the cable receiving inner space 30. The side wall 40 has an inner surface 43 and a rearwardly facing outer surface 44 that defines an aperture 45 having a diameter E that is less than the diameter B of the cable receiving inner space 30. At the rear end 36, an annular rear surface 50 is formed between the inner and outer surfaces 43 and 44. Thereafter, the surface 50 forms a front stop for the inner space 30 when the cover 15 is assembled to the main body 14, as shown in the cross-sectional view of Fig. 6A.

Returning to Figures 3 and 4, the rear end 36 of the cover 15 is designated by the spaced apart block 33 and void 34. The enlarged head of the block (as is readily apparent from Figure 4) extends radially inwardly into the aperture 45, and when the cover 15 engages the body 14, an inward pressure is applied at the forward end 23 of the body 14. Focus on the barb 31.

The inner cylinder 21 carries the body assembly 13. The inner cylinder 21 is shown in detail in Figures 5A-5D. The inner cylinder 21 is a hollow long cylindrical sleeve extending along the axis A and is rotationally symmetrical with respect to the axis A. The inner cylinder 21 has opposite front and rear ends 51 and 52, and opposite inner and outer surfaces 53 and 54. The outer surface 54 forms a helix 55 at a rear end 52 adjacent the inner cylinder 21 from which the helix 55 surrounds the outer surface 54 until about halfway between the front and rear ends 51 and 52. The thread 55 is sharp and has a sharp peak between its two slopes, forming about four turns of a spiral around the inner cylinder 21. The meaning of "spiral" means that the axial direction advances with the circumferential direction. The peak protrudes outward from the inner cylinder 21 in the radial direction. The spiral 55 is offset from the thread 27 in both the radial direction and the axial direction. The thread 27 is adjacent to the front end 23 of the body 14, and the spiral 55 is between the thread 27 and the rear end 24 of the body 14.

The spiral 55 is provided with a plurality of stops 56. Each stop 56 is a notch in the helix 55 that allows the barrier layer 90 of the cable 11 to move forward over the helix 55 but restricts the isolation layer 90 of the cable 11 from moving backward or backward in the helix 55. Therefore, the cable 11 can advance and lock on the inner cylinder 21 and cannot be withdrawn from the inner cylinder 21. Stop 56 is in each of the spirals 55 The quarter is formed at a quarter, so the quadrant of the circumference of the inner cylinder 21 is aligned in the axial direction. Each stop 56 is formed by a vertical side 57 facing the rear end 52 of the inner cylinder 21 and a beveled edge 58 facing the front end 51 of the inner cylinder. The vertical side 57 is a discontinuous break point on the helix 55, where the helix 55 is interrupted towards the longitudinal axis A and towards the radial direction from the top of the helix 55 on the outer surface 54 of the inner cylinder 21 to the root Face. The beveled edge 58 is raised from the heel of the thread 55 to the top thereof so that the thin or braided electrically conductive barrier can be returned to the helix 55 by the bevel 58 under the force of the hand. Conversely, the upside 57 is upright and the barrier layer cannot pass back through the riser 57 or back, thereby preventing the barrier layer from coming out of the spiral 55.

Three annular flanges are formed adjacent the front end 51 of the inner cylinder 21, so that the inner cylinder 21 has a stepped body. Each flange structure is similar and protrudes from the axis A in the radial direction. A first flange 60 is formed at the front end 51 of the inner cylinder 21. The third flange 62 has a smaller diameter than the second flange 61 and is behind the second flange 61. Referring to FIG. 6A, the cover 15 is mounted on the inner cylinder 21 at the third flange 62. When the cover 15 is attached to the inner cylinder 21, the front end 35 of the cover 15 and the flange 60 of the inner cylinder 21 together form an annular groove 63 for receiving the nut 20. The annular groove 63 limits the axial movement of the nut 20 on the inner cylinder 21.

The inner cylinder 21 is made of a conductive material and maintains a radio frequency connection between the nut 20 and the coaxial cable 11. The inner surface 53 of the inner cylinder 21 constitutes a cylindrical aperture 64, the size of which can hold the coaxial cable 11 tightly.

The nut 20 is mounted on the inner cylinder 21 at an annular groove 63 formed between the nut 20 and the cover 15. Referring to Figures 3 and 4, the mounting of the nut 20 is rotatable about the axis A so that the fitting 20 can be turned onto the female coaxial post. The nut 20 is a cylindrical sleeve having oppositely facing front and rear ends 70 and 71, an integrally formed ring portion 72 adjacent the front end 70, and an integrally formed nut portion 73 adjacent the rear end 71. The ring portion 72 has a smooth annular outer surface 74 and a threaded inner surface 75 that faces away from the coaxial post that can be used to engage the female. The nut portion 73 of the fitting 70 has a hexagonal outer surface 80 for receiving the mouthpiece of the tool. The inner side of the nut portion 73 has an inwardly extending annular ridge 81 which is placed into the annular groove 63 and rotatable therein. When the ridge 81 is placed in the annular groove 63, the fitting 20 cannot move forward and backward in the axial direction. The rear end 71 of the fitting 20 is an annular sleeve extending rearwardly from the ridge 81 to completely enclose and close the front portion 41 of the cover 15.

A cylindrical inner space 83 extends into the fitting 20 from the mouth portion 84 formed at the forward end 70 of the fitting 20. When the nut 20 is mounted to the inner cylinder 21, the front end 51 of the inner cylinder 21 forms a stop in the inner space 83 to prevent the fitting 20 from passing over the female coaxial column.

The operation of the connector 10 will be described below with reference to Figs. 6A and 6B. The connector 10 can be mounted to the coaxial cable 11 without special tools, and can be operated only by the structural features and components of the connector 10. In addition, it is also possible to prevent the connector 10 from being accidentally pulled out of the cable 11. Want The connector 10 is mounted to the coaxial cable 11, the cable 11 is aligned with the axis A, and the cable 11 is advanced in the direction indicated by the arrowed line F, and the cable 11 is threaded into the connector 10 at the rear end 24 of the body 14. The cable of the main body assembly 13 accommodates the inner space 30. The coaxial cable 11 is inserted into the cable housing inner space 30 contained by the main body 14 of the main body assembly 13. The cable 11 encounters the rear end 52 of the inner cylinder 21 almost immediately. When the rear end 52 of the inner cylinder 21 is hit, the isolation layer 90 and the sheath 91 of the cable 11 advance past the front end 52, and the inner conductor 12 and the dielectric insulator 92 enter the inner surface 53 of the inner cylinder 21. Aperture 64. The body assembly 13 of the connector 10 is then grasped by hand to rotate the body assembly 13 in a clockwise direction, but the fixed cable 11 does not move. It is also possible to fix the main body assembly 13 to rotate the cable 11 without moving, but it is generally easier to rotate the main body assembly 13 of the connector 10. Rotating the body assembly 13 causes the spiral 55 to bite into the barrier layer 90 of the cable 11 to engage the barrier layer 90. The body assembly 13 is rotated until the cable 11 fully reaches the rear surface 50 of the cover 15. As the body assembly 13 rotates over the cable 11, the barrier gradually passes over the stop 56 formed in the spiral 55.

When the cable 11 reaches the vicinity of the front end of the cable housing inner space 30, near the rear surface 50 of the cover 15, the thread 27 (which is relatively easily seen from Fig. 6A) engages the sleeve 91. The cable 11 is rotated to cause the thread 27 to bite into the sleeve 91, so that the cable 11 is more firmly fixed to the connector 10. When the cable 11 reaches the rear surface 50, the sleeve 91 passes over a vertical stop at the end of the thread 27. This stop is a stand instead of a ramp once the cable is crossed The stopper cannot be retracted beyond it, so the thread 27 cannot be withdrawn and the connector 10 is detached. Once fully assembled, the cable 11 is secured to the threads 27 and 55 and the inner cylinder 21 and is unable to move axially forward or backward and to disengage the connector 10. The rims 57 of the plurality of stops 56 bite into, jam the barrier layer 90 and limit any rearward movement thereof and the detachment helix 55 of the cable 11. In addition, the spacer layer 90 and the sleeve 91 are pressed between the outer surface 54 of the inner cylinder 21 and the inner surface 26 of the body 14, and the dielectric body 92 and the inner conductor are only inserted into the aperture 64 of the inner cylinder 21. Therefore, the cable 11 cannot be withdrawn from the connector 10.

In this arrangement, the barrier layer 90 is in electrical communication with the outer surface 54 of the inner cylinder 21, which in turn is in electrical communication with the nut 20, thereby maintaining electrical communication between the connector 10 and the cable 11. When the cable 11 is fully assembled to the connector 10, the inner conductor 12 extends through the mouth 84 of the nut 20 to engage the female coaxial post of the electronic component. The connector 10 thus fully assembled and fixed to the cable 11 is already usable. When the connector 10 is to be mounted to the female coaxial column, as long as the nut 20 of the connector 10 is grasped by hand and then the nut 20 is rotated over the female connecting post, the thread in the nut 20 can lock the female coaxial The connector 10 is fixed to the female coaxial column.

7-11B show a coaxial cable connector 110 of another example constructed and arranged in accordance with the principles of the present invention, assembled to a coaxial cable 11. As with the previous example, the connector 110 is exemplified by an F connector for an RG6 coaxial cable, but other types of coaxial cable connectors and other types of cables can be used in the following description. The connector 110 includes a two-piece cylindrical body assembly 13' identical to the body assembly 13 of the connector 10, and thus the constituent functions and elements of the body assembly 13' will be designated by the same reference numerals as the connector 10. The structural function and components of the body assembly 13' are distinguished from the connector 10 by an apostrophe ("'"). In fact, any apostrophe designation in the following description is identical to a structural function or component that is not identified by the same reference numeral. The body assembly 13' has both a body 14' and a cover 15'. The connector 110 also includes a coaxial nut 120 that is assembled to rotate the cover 15' to the body assembly 13'. The manner in which the nut 120 is coupled to the female coaxial post of the electronic component is different from the fitting 20 of the connector 10 because its structure is different from that of the connector 10 of the connector 10, as will be described later. Both the cover 15' and the nut 120 are carried on the inner cylinder 21' as shown in Figs. 11A and 11B, and the two figures are cross-sectional views taken along line 11-11 of Fig. 7. The inner cylinder 21' is also the same as the inner cylinder of the connector 10. Therefore, the structural functions and components of the inner cylinder 21' are also indicated by the same reference numerals as those used for the connector 10, except that the apostrophe is added. The longitudinal axis A' passes through the center of the connector 110. The body assembly 13', the nut 120 and the inner cylinder 21' are rotationally symmetric with respect to the longitudinal axis A', as shown in Figures 8A and 8B.

Referring to Figures 9, 10, 11A and 11B, the body 14' of the body assembly 13', like the body 14, is an elongate sleeve extending along the axis A', including a side wall 22', opposite front and rear ends 23' Inner and outer surfaces 25' and 26' opposite 24'. The inner surface 25' constitutes a cable housing inner space 30' sized and shaped to receive the coaxial cable 11. The inner surface 25' forms a three-quarter spiral 27' near the front end 23', and the spiral 27' is flat The slope 28 of the sliding inner surface 25' rises begins and ends with a vertical stop spiral about the inner surface 25' about three-quarters of the circumference. The diameter B' of the cable housing inner space 30' is defined by the inner surface 25'. The front and rear ends 23' and 24' are both open for access to the cable housing inner space 30'. The outer surface 26' of the side wall 22' is provided with an axial groove or groove 29' to enhance the grip on the body 14'. The outer surface 26' defines the outer diameter C' of the body 14'.

Referring to Figures 9 and 10, the front end 23' of the body 14' has an engagement structure that engages the cover 15'. The body 14' is similar to the body 14 of the connector 10 and has a plurality of semi-annular barbs 31' spaced apart from one another by block segments 32'. The complementary engaging structure on the cover 15' is a plurality of blocks 33' extending rearwardly with an enlarged head to catch the barbs 31'. The blocks 33' are separated by a gap 34', the size of the gap 34' The block section 32' can be accommodated. The structure of the cover 15' is similar to that of the cover 15, for example, the front end 35', the opposite end rear end 36', the stepped side wall 40', the front portion 41', the rear portion 42', and the rear portion 42' diameter D' are . The side wall 40' has an inner surface 43', a back facing outer surface 44', a diameter E aperture 45', and an annular rear surface 50'.

The structure of the inner cylinder 21' is similar to the inner cylinder 21 of the connector 10. The inner cylinder 21' has a hollow cylindrical sleeve extending along the axis A' and rotationally symmetric with respect to the axis A'. The inner cylinder 21' includes opposite front and rear ends 51' and 52', opposite inner and outer surfaces 53' and 54', and one from the rear end 52' to the front and rear ends 51. A spiral 55' around the outer surface 54' is about halfway between 'and 52'. Spiral 55' is sharp Between the two slopes is a sharp top, about four turns of spiral around the inner cylinder 21'. "Spiral" means that the spiral 55' advances simultaneously with the circumferential direction in the axial direction. The top portion protrudes outward from the inner cylinder 21' toward the radial direction. The helix 55' includes a plurality of stops 56', each of which is similar to the helix 55, and is formed by a notch 57' and a beveled edge 58'. The inner cylinder 21' also includes three annular flanges 60', 61', and 62' (as seen from Figure 11A), and an annular groove 63'. The inner cylinder 21' is constructed of a conductive material to maintain a radio frequency connection between the nut 120 and the coaxial cable 11'. The inner surface 53' of the inner cylinder 21' surrounds and defines a cylindrical aperture 64' sized to closely receive the coaxial cable 11'.

The nut 120 is mounted to the inner cylinder 21' in an annular groove 63' formed between the fitting 21' and the lid 15'. The nut 120 is mounted to rotate about the axis A' so that the nut 120 can be rotationally locked to the female threaded post of an electronic component. The nut 120 is a cylindrical sleeve having a collet portion 172 that is integrally formed opposite the front and rear ends 170 and 171, adjacent to the front end 170, and a grip portion 173 that is integrally formed near the rear end. The collet portion 172 has a smooth conical outer surface 174 and split fingers 175 formed on the inner surface 176 for grasping the female coaxial column. Each finger 175 has a tab 177 that extends from the leaflet 178 at the front end 170 toward the rear end 171 of the nut 120. The finger 175 continuously surrounds the inner surface 176 of the collet portion 172 of the nut 120, and only the slit 179 between the fingers 175 is cut.

The grip portion 173 of the fitting 170 has an annular outer surface 180 with A plurality of concentric annular barbs 181 are just behind the jaw portion 172. The barbs 181 enhance the grip when the connector 110 is pushed onto the female coaxial column. The inner surface 182 of the grip portion 173 has a plurality of spaced apart long prismatic posts 183 extending inwardly toward the axis A' in the radial direction. The post is a long prismatic extension of the inner surface 182 that extends into the interior of the nut 120. The post 183 extends into the annular groove 83' to allow the nut 120 to rotate on the body assembly 13' when the nut 120 is assembled to the body assembly 13' of the connector 110. When the post 183 snaps into the groove 83', the nut 120 cannot move back and forth in the axial direction. The rear end 171 of the nut 120 forms an annular sleeve that extends rearward beyond the cylinder and is entirely over the portion 41' of the cover 15' and is closed.

A cylindrical inner space 184 extends into the nut 120 from a mouth 185 formed at the forward end 170 of the nut 120. When the nut 120 is mounted on the inner cylinder 21', the front end 51' of the inner cylinder 21' forms a stop in the inner space 184, so that the nut 120 cannot be oversized and installed to the female On the coaxial column.

The operation of the connector 110 will be described below with reference to Figs. 11A and 11B. The connector 110 can be mounted to a coaxial cable without tools, and can be operated only by the structural functions and components of the connector 110. In addition, it is also possible to prevent the connector 110 from being accidentally pulled out of the cable. To mount the connector 110 to the coaxial cable 11, the cable 11 must be aligned with the axis A' and the cable 11 is advanced in the direction indicated by the arrowed line F', and the cable 11 is passed through the rear end 24' of the body 14'. The cable into the body assembly 13' of the connector 110 houses the inner space 30'. The coaxial cable 11 is inserted into the cable housing inner space 30' accommodated by the main body 14' of the main body assembly 13', the cable 11 almost immediately encounters the rear end 52' of the inner cylinder 21'. When the rear end 52' of the inner cylinder 21' is hit, the isolation layer 90 and the sheath 91 of the cable 11 advance past the front end 52', and the inner conductor 12 and the dielectric insulator 92 enter the inner cylinder 21'. Aperture 64' in surface 53'.

The body assembly 13' of the connector 110 is then grasped by hand, and the body assembly 13' is rotated in a clockwise direction, but the fixed cable 11 is not moved. It is also possible to fix the main body assembly 13' to rotate the cable 11 without moving, but it is generally easier to rotate the main body assembly 13' of the connector 110. Rotating the body assembly 13' causes the spiral 55' to bite into the barrier layer 90 of the cable 11 to engage the barrier layer 90. The body assembly 13' is rotated until the cable 11 fully reaches the rear surface 50' of the cover 15'. As the body assembly 13 rotates over the cable 11, the barrier gradually passes over the stop 56' formed in the helix 55'.

When the cable 11 reaches the front end of the cable housing inner space 30' near the rear surface 50' of the cover 15', the thread 27' (as seen more easily from Fig. 11A) engages the sleeve 91. The cable 11 is rotated to cause the thread 27' to bite into the sleeve 91 to secure the cable 11 to the connector 110 more securely. When the cable 11 reaches the rear surface 50', the sleeve 91 passes over a vertical stop at the end of the thread 27'. This stop is a standing end rather than a ramp, and once the cable 11 passes over the stop, it cannot be retracted past it, so the cable 11 cannot exit the connector 110. Once fully assembled, the cable 11 is secured to the thread 55' and cannot be moved axially forward or backward to the eject connector 110. The vertical edge 57' of the plurality of stops 56' bites into, The spacer 90 is latched and any rearward movement of the cable 11 and the detachment helix 55' of the cable 11 are restricted. In addition, the isolation layer 90 and the sleeve 91 are pressed between the outer surface 54' of the inner cylinder 21' and the inner surface 26' of the main body 14', and the dielectric body 92 and the inner conductor are only inserted into the inner cylinder 21'. Within the aperture 64', the cable 11 is therefore not able to be withdrawn from the connector 110. In this arrangement, the isolation layer 90 is in electrical communication with the outer surface 54' of the inner cylinder 21', and the inner cylinder 21' is in electrical communication with the nut 120, thereby maintaining electrical communication between the connector 110 and the cable 11. .

When the cable 11 is fully assembled to the connector 110, the inner conductor 12 extends through the mouth 184 of the nut 120 to engage the female coaxial post of the electronic component. The connector 110 thus fully assembled and fixed to the cable 11 is already usable. To mount the connector 110 to the female coaxial post, the fingers 175 are engaged with the female coaxial post by simply grasping the nut 120 of the connector 110 by hand and then pushing the nut 120 onto the female connecting post. The connector 10 is fixed to the female coaxial column. The fitting 20 is typically provided with a threaded or tight helix. When the fitting 20 is fitted over the female coaxial post, the flap 177 on the inside of the jaw portion 172 of the nut 120 is deflected outward in the radial direction and is pressed against The inner surface 176 of the jaw portion 172 is between the parent coaxial post. Therefore, the jaw portion 172 is fixed to the female coaxial post. Since the axial rearward movement of the connector 10 presses the fin 177 inwardly in the radial direction against the female coaxial column, and the airfoil bites the thread or the spiral of the female coaxial column, the nut 120 can resist the coaxial connection from the mother. Pull back in the axial direction.
