Description

Technical Field

[0001] The utility model relates to the technical field of assembly tools, in particular to a tool structure for assembling a radio frequency connector. Background Art

[0002] A radio frequency connector is generally considered as an element installed on a cable or an instrument. As an element for electrical connection or separation of a transmission line, it is widely used in the communication field.

[0003] Generally, a radio frequency connector is threadedly connected with a connector female head having a threaded head to achieve communication interaction. When performing radio frequency tests, it is necessary to continuously separate and connect the radio frequency connector, which is very inconvenient. Therefore, there is a radio frequency connector that can be inserted into a connector female head having a threaded head, which includes a card slot, a magnetic bead, and a sliding sleeve. An accommodating groove for placing the magnetic bead is provided on the outer side wall of the card slot. The sliding sleeve is sleeved outside the card slot, so that the magnetic bead can partially extend from the accommodating groove into the radio frequency connector. After the radio frequency connector is inserted into the connector female head, the magnetic bead partially protrudes through the sliding sleeve, is embedded in the threaded groove of the connector female head, and is tightly abutted, thereby providing a certain anti - detachment ability.

[0004] However, there are certain difficulties in assembling the magnetic beads of the above - mentioned radio frequency connector. Specifically, to ensure a certain anti - detachment ability, multiple magnetic beads are generally provided and evenly distributed along a ring, so as to make the force on the entire circumference balanced. However, when assembling the magnetic beads, it is necessary to first place the magnetic beads into the accommodating groove, and then sleeve the sliding sleeve to limit the magnetic beads in the accommodating groove. However, multiple magnetic beads evenly distributed in a ring cannot be limited in the accommodating groove at the same time, resulting in difficulties in assembling the radio frequency connector. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a tool structure for assembling a radio frequency connector.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A tooling structure for assembling a radio frequency connector, the radio frequency connector including a card slot, a magnetic bead, a sliding sleeve and a sliding sleeve clamp. An accommodation groove for placing the magnetic bead is provided on the outer side wall of the card slot. The sliding sleeve clamp is sleeved on the card slot. The tooling structure includes a base, a positioning rod, an annular magnetic block and a pressing head. A positioning groove for fixing the card slot is provided on the base. A protruding portion is provided on the positioning rod. The positioning rod is inserted into the card slot and the protruding portion abuts against a step located inside the card slot. The annular magnetic block is sleeved on the positioning rod and abuts against the protruding portion. When the annular magnetic block abuts against the protruding portion, the annular magnetic block is disposed opposite to the accommodation groove. The pressing head moves towards the positioning groove to enable the sliding sleeve to be sleeved on the card slot with the magnetic bead and cooperate with the sliding sleeve clamp.

[0008] Further, the number of the accommodation grooves is multiple, and the multiple accommodation grooves are distributed in a spiral line along the outer side wall of the card slot. The length of the annular magnetic block in the axial direction of the card slot is greater than the coverage range of all the accommodation grooves in the axial direction of the card slot.

[0009] Further, the material of the annular magnetic block is a strong magnetic material.

[0010] Further, there is a spacing between the annular magnetic block and the inner side wall of the card slot, and the spacing is adapted to the distance that the magnetic bead protrudes from the accommodation groove towards the inside of the card slot.

[0011] Further, when the positioning rod is inserted into the card slot, the end of the positioning rod away from the positioning groove passes through the sliding sleeve to the outside.

[0012] Further, the accommodation groove is a tapered hole. The axial direction of the tapered hole is perpendicular to the plane where the card slot is located, and the small hole end of the tapered hole is located on the inner side wall of the card slot. The minimum diameter of the tapered hole is smaller than the diameter of the magnetic bead.

[0013] The beneficial effects of the present utility model are:

[0014] The tooling structure for assembling a radio frequency connector provided by the present utility model includes a base, a positioning rod, an annular magnetic block and a pressing head. A positioning groove for fixing the card slot is provided on the base. A protruding portion is provided on the positioning rod. The positioning rod is inserted into the card slot and the protruding portion abuts against a step located inside the card slot. The annular magnetic block is sleeved on the positioning rod and abuts against the protruding portion. When the annular magnetic block abuts against the protruding portion, the annular magnetic block is disposed opposite to the accommodation groove. Through the magnetic attraction of the annular magnetic block, the magnetic bead can be restricted in the accommodation groove and not slide out when the sliding sleeve is not assembled. Finally, the pressing head moves towards the positioning groove to enable the sliding sleeve to be sleeved on the card slot with the magnetic bead and cooperate with the sliding sleeve clamp. The sliding sleeve restricts the magnetic bead to be placed in the accommodation groove, thereby realizing the assembly of the radio frequency connector. Description of the Drawings

[0034] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments as follows:

[0035] As Figures 1 - 13 shown, a tooling structure for assembling a radio frequency connector provided by the present utility model, the radio frequency connector includes a card slot, a magnetic guiding bead, a sleeve and a sleeve clamp, an accommodating groove for placing the magnetic guiding bead is provided on the outer side wall of the card slot, the sleeve clamp is sleeved on the card slot, and the tooling structure includes a base, a positioning rod, a ring magnet and a press head; a positioning groove for fixing the card slot is provided on the base, a protrusion is provided on the positioning rod, the positioning rod is inserted into the card slot and the protrusion abuts against a step located inside the card slot, the ring magnet is sleeved on the positioning rod and abuts against the protrusion, when the ring magnet abuts against the protrusion, the ring magnet is arranged opposite to the accommodating groove, and the press head moves towards the positioning groove to enable the sleeve to be sleeved on the card slot with the magnetic guiding bead and cooperate with the sleeve clamp.

[0036] It can be seen from the above description that the present utility model has the following beneficial effects:

[0037] A tooling structure for assembling a radio frequency connector provided by the present utility model includes a base, a positioning rod, a ring magnet and a press head; a positioning groove for fixing the card slot is provided on the base, a protrusion is provided on the positioning rod, the positioning rod is inserted into the card slot and the protrusion abuts against a step located inside the card slot, the ring magnet is sleeved on the positioning rod and abuts against the protrusion, when the ring magnet abuts against the protrusion, the ring magnet is arranged opposite to the accommodating groove, through the magnetic attraction of the ring magnet, the magnetic guiding bead can be restricted in the accommodating groove and not slide out when the sleeve is not assembled, and finally the press head moves towards the positioning groove to enable the sleeve to be sleeved on the card slot with the magnetic guiding bead and cooperate with the sleeve clamp, and the sleeve plays a role in restricting the magnetic guiding bead to place it in the accommodating groove, thereby realizing the assembly of the radio frequency connector.

[0038] Furthermore, the number of the accommodating grooves is multiple, and the multiple accommodating grooves are distributed in a spiral on the outer side wall of the card slot, and the length of the ring magnet in the axial direction of the card slot is greater than the coverage range of all the accommodating grooves in the axial direction of the card slot.

[0039] As can be seen from the above description, through the above structural design, it can better conform to the pitch of the thread of the female connector, so the magnetic beads placed in the receiving groove can fit more tightly with the thread of the female connector, further improving the tightness of the mutual fit.

[0040] Furthermore, the material of the annular magnetic block is a strong magnetic material.

[0041] As can be seen from the above description, by using a ring-shaped strong magnetic material, the magnetic beads in the annularly distributed receiving grooves can be jointly adsorbed in the receiving grooves. At this time, it is convenient to sleeved the sliding sleeve into the card slot to limit the magnetic beads in the receiving groove, and then the annular magnetic block can be taken out.

[0042] Furthermore, there is a gap between the annular magnetic block and the inner side wall of the card slot, and the gap is adapted to the distance that the magnetic bead protrudes from the receiving groove into the card slot.

[0043] As can be seen from the above description, setting the gap and making the gap adapted to the distance that the magnetic bead protrudes from the receiving groove into the card slot facilitates the removal of the annular magnetic block after the sliding sleeve is assembled.

[0044] Furthermore, when the positioning rod passes through the card slot, the end of the positioning rod away from the positioning groove passes through the sliding sleeve to the outside.

[0045] As can be seen from the above description, through the above specific design, the positioning rod can be easily removed. Since the annular magnetic block is sleeved on the positioning rod, when the positioning rod is removed, the annular magnetic block can be taken out together with the positioning rod, and the operation is convenient.

[0046] Furthermore, the receiving groove is a tapered hole, the axis of the tapered hole is perpendicular to the plane where the card slot is located, and the small-hole end of the tapered hole is located on the inner side wall of the card slot, and the minimum diameter of the tapered hole is smaller than the diameter of the magnetic bead.

[0047] As can be seen from the above description, through the above specific design, by using the "sliding property" of the magnetic beads, the mating of the connectors is simple and fast. By the way of helical axial incremental uniform distribution of the magnetic beads, the magnetic beads are embedded in the thread grooves of the female connector at multiple angles within one pitch, and the docking is stable and reliable. The tapered hole can effectively limit the magnetic beads. Especially when the magnetic bead is at the minimum diameter of the tapered hole, the position of the magnetic bead can be accurately limited, so that it can be accurately matched with the thread groove.

[0048] The following lists several preferred embodiments or application embodiments to help those skilled in the art better understand the technical content of the present invention and the technical contributions made by the present invention compared with the prior art:

[0049] Preferred Embodiment 1:

[0050] Such as Figures 1 to 13, a tooling structure for assembling a radio frequency connector provided by the present utility model, wherein the radio frequency connector includes a connector body 2, a sliding sleeve mechanism 3, and a card slot mechanism;

[0051] The connector body 2 includes a connector housing 21, an inner conductor 22, an insulator 23, and a retaining ring 24; the inner conductor 22 is arranged inside the connector housing 21 and is coaxially arranged with the connector housing 21. The internal structure, dimensions, and mating interface formed are all designed according to the radio frequency standard interface and radio frequency impedance requirements. The connector housing 21 is a metal part, and the material is preferably copper or stainless steel.

[0052] The insulator 23 is sleeved on the inner conductor 22, and the outer side wall of the insulator 23 is clamped with the inner side wall of the connector housing 21. The retaining ring 24 is sleeved on the outer side wall of the connector housing 21 to form a retaining end face; specifically, the retaining ring 24 is a metal ring with a step on both the inside and outside, and is press-fitted on the first step of the connector housing to form two retaining end faces

[0053] The card slot mechanism is movably sleeved on the connector housing 21. The card slot mechanism includes a card slot body 1, a magnetic bead 15, and a second spring 16. The second spring 16 is sleeved on the connector housing 21. The card slot mechanism and the connector housing 21 are respectively in contact with both ends of the second spring 16, so that the card slot mechanism can make elastic movement within a certain range on the connector housing under the action of the second spring and the retaining ring; in this embodiment, the magnetic bead 15 can be an existing iron bead.

[0054] Specifically, the card slot mechanism is a metal part and is movably sleeved on the connector housing through a stepped hole inside it. The card slot body 1 is provided with an annular extension wall 11. The annular extension wall 11 is provided with four axially extending strip-shaped through slots 13. The width of the strip-shaped through slots 13 in the circumferential direction of the annular extension wall is 1 mm, and the depth of the strip-shaped through slots 13 in the axial direction of the annular extension wall is 4 mm. The four strip-shaped through slots 13 are evenly distributed so that the annular extension wall is divided into four mutually spaced arc-shaped side walls 14. At least one tapered hole is provided on each arc-shaped side wall 14. In this embodiment, one tapered hole can be provided on each arc-shaped side wall. A magnetic bead is arranged in each tapered hole. The minimum diameter of the tapered hole is smaller than the diameter of the magnetic bead, and the magnetic bead can protrude towards the inner side of the annular extension wall. In this embodiment, the dimensions of the tapered hole are designed according to the dimensions of the magnetic bead. The small hole dimension of the tapered hole is not larger than the dimension of the magnetic bead. The magnetic bead can move radially in the tapered hole and can protrude inward.

[0055] Four conical holes are distributed along the helix of the annular extension wall. The helix increment of the helix is adapted to the pitch on the female connector 4. Specifically, the helix increment of the helix is 0.71 mm. The four conical holes are within a pitch range, which can make the overall structure more compact. According to the above helix increment, the assembly requirements of most standard RF coaxial connectors can be met, such as 3.5 mm, 2.9 mm, TNC type, N type and other standard RF coaxial connectors.

[0056] The corresponding increment sizes and magnetic beads sizes of several typical screw - mating RF connectors are as shown in Table 1 below:

[0057] Connector model Increment (mm) Ferromagnetic bead diameter (mm) SMA\2.92\3.5 0.71 0.7~0.75 TNC 0.91 0.8~0.9 N 1.06 0.9~1.0

[0058] Table 1

[0059] The sliding sleeve mechanism 3 includes a sliding sleeve 31, a first spring 32 and a sliding sleeve clamp 33; the first spring 32 is sleeved inside the sliding sleeve 31. One end of the first spring 32 abuts against the sliding sleeve step, and the other end of the first spring 32 abuts against the step of the clamping groove; the sliding sleeve clamp 33 is arranged on the outer side wall of the clamping groove body to limit the movement range of the sliding sleeve on the clamping groove. Under the action of the anti - withdrawal ring at the rear end, the sliding sleeve mechanism realizes limited axial movement on the RF connector. Under the action of the first spring, the sliding sleeve freely slides forward to the front end of the connector.

[0060] The sliding sleeve 31 is made of metal. Under the action of an external force, when the sliding sleeve moves backward, the first inner circle of the sliding sleeve and the inside of the clamping groove body jointly form a cavity. The height of this cavity is slightly smaller than the diameter of the magnetic bead, so that the magnetic bead can move limitedly in the inner diameter direction of the tapered groove of the clamping groove.

[0061] A first inner hole 311 and a second inner hole 312 which are relatively communicated are arranged at the front end of the sliding sleeve 31. The first inner hole 311 is a straight hole at the front section, and the second inner hole 312 is a hole with a certain taper at the rear end, that is, a guiding surface is arranged on the inner side wall of the sliding sleeve. The guiding surface is used for cooperating with the locking part, so that the sliding sleeve can slide away from the anti-backlash ring and press the locking part (i.e., the magnetic guiding bead) into the accommodating groove (i.e., the tapered hole). And the distance of the guiding surface in the radial direction of the connector housing is smaller than the size of the locking part, so that the locking part can be kept in the accommodating groove during the movement of the sliding sleeve, which can prevent the locking part from coming out after assembly and ensure the structural stability. The second inner hole is slightly larger than the outer diameter of the clamping groove body, and the magnetic guiding bead can be pressed into a size tangent to the thread surface of the mating female connector. A chamfer is used for transition between the second inner hole and the first inner hole, which can facilitate the forward sliding of the sliding sleeve and the pressing of the magnetic guiding bead, so that the magnetic guiding bead is embedded in the thread 41 of the mating female connector 4. And, due to the limitation of the tapered hole at the rear section of the second inner hole, if the connector body is pulled, the sliding sleeve will further radially press the magnetic guiding bead, and due to the fact that the clamping groove itself has a certain radial deformation ability, the magnetic guiding bead and the thread are in a state of being clamped tighter and tighter, playing a certain self-locking role.

[0062] The above technical solution realizes the quick and self-locking connection between the RF connector and the conventional connector by embedding the magnetic guiding bead in the thread. By utilizing the "sliding property" of the magnetic guiding bead, the mating of the connectors is simple and fast. Further, in the way that the magnetic guiding beads are evenly distributed with a helical axial increment, the magnetic guiding beads are embedded in the thread grooves at multiple angles within one pitch, and the docking is stable and reliable. And, the clamping groove mechanism is designed into a spring movable mechanism, avoiding the factor of the uncertainty of the starting point of the mating end thread. When disassembling the connector, the sliding screw sleeve needs to be pulled backward. The magnetic guiding bead loses the radial restraint force, and the connector can be easily taken out by utilizing the "rolling property" of the magnetic guiding bead.

[0063] The tooling structure includes a base 5, a positioning rod 6, an annular magnetic block 7 and a pressing head 8; a positioning groove 51 for fixing the clamping groove is arranged on the base 5. A protruding part 61 is arranged in the middle of the positioning rod 6, and the protruding part 61 matches the radial space inside the clamping groove. Specifically, the protruding part is in a circular ring shape. When the clamping groove is installed in the positioning groove, the positioning rod vertically penetrates through the clamping groove, that is, the positioning rod and the clamping groove are coaxial, and the protruding part abuts against the step located inside the clamping groove. The annular magnetic block 7 is sleeved on the positioning rod 6 and abuts against one end surface (i.e., the surface away from the positioning groove) of the protruding part 61 in the axial direction of the clamping groove. When the annular magnetic block 7 abuts against the protruding part 61, the annular magnetic block is arranged opposite to the accommodating groove. The pressing head 8 moves towards the direction of the positioning groove 51 so that the sliding sleeve is sleeved on the clamping groove with the magnetic guiding bead and cooperates with the sliding sleeve clamp 33.

[0064] In this embodiment, the length of the annular magnetic block 7 in the axial direction of the card slot is greater than the coverage range of all the receiving grooves in the axial direction of the card slot. Through the above structural design, an inward magnetic attraction force can be provided for all the magnetic conduction beads, so that all of them are received in the receiving grooves.

[0065] The material of the annular magnetic block 7 is a strong magnetic material. Specifically, a ring-shaped strong magnetic material is adopted, which can realize jointly adsorbing the magnetic conduction beads in the annularly distributed receiving grooves into the receiving grooves. At this time, it is convenient to sleeved the sliding sleeve into the card slot to limit the magnetic conduction beads in the receiving grooves, and then the annular magnetic block can be taken out.

[0066] There is a distance between the annular magnetic block 7 and the inner side wall of the card slot, and the distance is adapted to the distance that the magnetic conduction bead protrudes from the receiving groove into the interior of the card slot. Setting the distance and making the distance adapted to the distance that the magnetic conduction bead protrudes from the receiving groove into the interior of the card slot is convenient for taking out the annular magnetic block after the sliding sleeve is assembled.

[0067] When the positioning rod 6 passes through the card slot, the end of the positioning rod 6 away from the positioning groove passes through the sliding sleeve to the outside. Through the above specific design, the positioning rod can be conveniently taken out. Since the annular magnetic block is sleeved on the positioning rod, when the positioning rod is taken out, the annular magnetic block can be taken out together with the positioning rod, and the operation is convenient.

[0068] The present utility model has been described by the above related embodiments and the accompanying drawings. However, the above embodiments are only examples for implementing the present utility model. It must be pointed out that the disclosed embodiments do not limit the scope of the present utility model. On the contrary, modifications and equivalent arrangements included in the spirit and scope of the claims are all included in the scope of the present utility model.
