Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wiring connectors, in particular to a shielding ring and a cable assembly. Background Art
[0002] In the field of in-vehicle intelligent network connectors, wiring connectors are usually used to transmit RF analog / digital signals. The structure of the shielding ring of the wiring connector is as follows: Figure 1 As shown, the shielding ring 1 is generally made of bent metal material. The shielding ring 1 is an open ring with an adaptable extension ear 101 and a groove 102 at both ends of the circumference. The shielding ring 1 is an integrated structure from front to back and is wrapped around the outside of the cable shielding layer after being compressed. The shielding ring, cable, and outer conductor are assembled into a cable assembly. Figure 2 As shown, the cable 2 includes an inner core 201, an insulating layer 202, an aluminum foil layer 203, a shielding layer 204 and an outer sheath 205 which are stacked in sequence from the inside to the outside. During assembly, the outer sheath 205 at one end of the cable is first peeled off to expose the shielding layer 204, and then the shielding ring 1 is crimped to the outside of the shielding layer 204, and then the shielding layer 204 is folded 180° and attached to the outside of the shielding ring 1. Finally, the outer conductor 3 is crimped to the shielding layer attached to the outside of the shielding ring 1. The shielding ring 1 is located between the cable 2 and the outer conductor 3, and can play a role in fixing and supporting the shielding layer 204 attached to the outside of the shielding ring 1 after being folded. The shielding layer 204 attached to the outside of the shielding ring 1 is squeezed by the outer conductor 3 and the shielding ring 2, thereby achieving reliable conduction between the outer conductor 3 and the shielding layer 204 of the cable. Figure 2 As shown in the figure, the outer conductor 3 is an integrated structure as a whole, including an outer conductor front section 301 and an outer conductor rear section 302. The outer conductor front section 301 is crimped on the shielding layer 204 attached to the outside of the shielding ring 1 to achieve reliable conduction between the outer conductor 3 and the shielding layer 204 of the cable, and the outer conductor rear section 302 is crimped on the outer wire skin 205 to protect the cable 2 and prevent the outer wire skin from retreating.
[0003] Since different types of cables have different wire diameters, a set of outer conductors and shielding rings with matching sizes need to be customized for each type of cable. The outer conductor has a complex structure and needs to be manufactured using a special mold, which has a high mold cost, resulting in a high overall production cost for the cable assembly.

[0040] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.
[0041] The cable assembly of the present invention is improved on the basis of the existing cable assembly. The shielding ring and outer conductor of the existing cable assembly can only be applicable to specific types of cables. The shielding ring and outer conductor need to be customized separately for different types of cables. The cost of the outer conductor mold is relatively high, resulting in a high overall manufacturing cost of the cable assembly. The outer conductor of the cable assembly of the present invention can be applicable to cables of various different wire diameters, thereby solving the problem of high cost.
[0042] The scheme principle of the cable assembly of the utility model is as follows: the shielding ring is designed as a segmented structure, including a shielding layer crimping section and a wire skin crimping section, the shielding layer crimping section is used to wrap and crimp on the shielding layer of the cable, the wire skin crimping section is used to wrap and crimp on the outer wire skin of the cable, the shielding layer crimping section and the wire skin crimping section are axially connected through a transition section, the outer conductor is crimped on the outside of the shielding layer crimping section and the wire skin crimping section of the shielding ring, and the outer conductor is no longer crimped on the outer wire skin of the cable, so that the size of the outer conductor is not restricted by the wire diameter of the cable, the outer conductor can be made into a standard part, the outer conductor is universal, the thickness of each segment of the shielding ring can be adjusted according to the wire diameter of the cable to ensure that the thickness of each segment of the shielding ring is sufficient to fill the gap between the cable and the outer conductor, and in the production and manufacturing, for cables with different wire diameters, only multiple sets of shielding rings and one set of outer conductors need to be produced, and a set of outer conductor manufacturing molds need to be developed, thereby greatly reducing the cost and management cost of the outer conductor mold, and the shielding ring itself is a simple stamping part, which is easy and fast to manufacture and has low cost, thereby greatly reducing the manufacturing cost of the cable assembly.
[0043] Embodiments of the cable assembly of the utility model:
[0044] like Fig.10 As shown, the cable assembly includes a cable 2, a shielding ring 1 and an outer conductor 3. The shielding ring 1 is crimped to the outside of the cable 2, and the outer conductor 3 is crimped to the outside of the shielding ring 1. The cable 2 includes an inner core 201, an insulating layer 202, an aluminum foil layer 203, a shielding layer 204 and an outer sheath 205 which are stacked in sequence from the inside to the outside. The outer sheath 205 at one end of the cable is peeled off to expose the shielding layer 204. The front section of the shielding ring 1 is crimped to the outside of the shielding layer 204, and the rear section is crimped to the outside of the outer sheath 205. The front section 301 of the outer conductor is crimped to the shielding layer 204 which is attached to the outside of the shielding ring 1 after being folded, so as to achieve reliable conduction between the outer conductor 3 and the shielding layer 204 of the cable 2. The rear section 302 of the outer conductor is crimped to the rear section of the shielding ring 1.
[0045] The structure of the shielding ring is as follows Figure 3-5 As shown, the shielding ring is a segmented structure as a whole, including a front section and a rear section. The front section is a shielding layer crimping section 103 used to wrap and crimp on the shielding layer of the cable, and the rear section is a wire skin crimping section 105 used to wrap and crimp on the outer wire skin of the cable. The shielding layer crimping section 103 and the wire skin crimping section 105 are both open rings, and the two are axially connected by a transition section 104. Figure 5 As shown in the figure, the transition section 104 is a reduced diameter section, and the wrapping angle in the circumferential direction is smaller than the shielding layer crimping section 103 and the wire skin crimping section 105. The transition section 104 is used to form a stop limit with the necking section of the outer conductor in the front-to-back direction, i.e., in the axial direction, to prevent the shielding ring and the cable from separating when the cable is pulled hard. After peeling off a length of the outer wire skin 205 at one end of the cable 2, the shielding layer 204 is exposed. Fig.10 As shown in , the shielding layer crimping section 103 is crimped on the shielding layer 204, the wire skin crimping section 105 is crimped on the outer wire skin 205, and the transition section 104 is wrapped on the exposed shielding layer 204 located on the rear side of the shielding layer crimping section 103, so that the circumferential wrapping angle of the transition section 104 is smaller than that of the shielding layer crimping section 103 and the wire skin crimping section 105, so that the processing difficulty of the transition section 104 can be reduced during stamping, which is convenient for the processing of the shielding ring. Of course, in other embodiments, the circumferential wrapping angle of the transition section can also be equal to or greater than the circumferential wrapping angle of the shielding layer crimping section and the wire skin crimping section. The size of the circumferential wrapping angle of the transition section directly affects the opening size of the transition section, and it is necessary to ensure that the cable is large enough to pass through the opening.
[0046] like Figure 3-5As shown in , the shielding layer crimping section 103 and the wire skin crimping section 105 both include an arc section 106 and a flat section 107 connected at both ends of the arc section 106 and extending outwardly obliquely. The arc section 106 is used to fit with the cable, and the two flat sections 107 are used to be compressed and wrapped on the corresponding parts of the cable. The flat sections 107 at both ends of the arc section 106 extend outwardly obliquely, thereby forming a flared structure, which is convenient for the cable to pass through the openings of the shielding layer crimping section 103 and the wire skin crimping section 105, so that the shielding layer crimping section 103 and the wire skin crimping section 105 are easier to buckle on the outside of the cable. The arc section 106 directly fits with the cable, and the flat sections 107 at both ends of the arc section 106 are pressed to deform and wrap around the outside of the cable. The shielding ring is formed by stamping and bending a metal material. During stamping and forming, only a small arc section 106 needs to be stamped and formed, making the shielding ring processing simpler and faster. Of course, in other embodiments, the shielding layer crimping section and / or the wire sheath crimping section can also be an arc-shaped section as a whole. After the shielding layer crimping section and the wire sheath crimping section are buckled on the outside of the cable, pressure is applied to the arc-shaped section to deform it as a whole and wrap it around the outside of the cable.
[0047] The thickness of the shielding layer crimping section 103 and the wire skin crimping section 105 are not equal. The outer conductor 3 is a universal structure, and the wire diameters of different types of cables 2 are different, so the gap between the outer conductor 3 and the cable 2 will also change accordingly. The thickness of the shielding layer crimping section 103 and the wire skin crimping section 105 can be adjusted according to the size of the gap to ensure that the gap is filled. The thickness of the shielding layer crimping section 103 and the wire skin crimping section 105 are not equal, which can ensure that the shielding ring 1 can be tightly pressed and contacted with the front section 301 of the outer conductor and the rear section 302 of the outer conductor, thereby improving the pressing reliability. Of course, in actual applications, it is also feasible to make the thickness of the shielding layer crimping section and the wire skin crimping section equal. At this time, in order to ensure the pressing effect, there will be a period of excessive pressing.
[0048] like Figure 3-5 As shown in the figure, the inner surfaces of the transition section 104 and the shielding layer crimping section 103 are flush, the outer surface of the transition section 104 is concave inwardly from the outer surface of the shielding layer crimping section 103, and a front step surface facing backward is formed at the connection between the transition section 104 and the shielding layer crimping section 103, the thickness of the transition section 104 and the wire skin crimping section 105 are equal, and the outer surface of the transition section 104 is concave inwardly from the outer surface of the wire skin crimping section 105, and a rear step surface facing forward is formed at the connection between the transition section 104 and the wire skin crimping section 105. The front step surface and the rear step surface are used to form a stop limit with the necking section of the outer conductor in the front-to-back direction, i.e., in the axial direction, to prevent the shielding ring and the cable from being separated when the cable is pulled vigorously.
[0049] Preferably, the shielding layer crimping section 103, the transition section 104 and the wire skin crimping section 105 are an integrated structure, and three sections are stamped out from a metal plate during processing. The manufacturing is simple and fast, the cost is low, and it is more conducive to the shielding ring to be deformed under pressure and wrapped around the outside of the cable. Of course, the shielding ring can also be a split structure. For example, in another embodiment, the shielding layer crimping section and the transition section are an integrated structure, and the wire skin crimping section is a separate section. When used, the shielding layer crimping section and the transition section can be crimped to the outside of the shielding layer first, and then the wire skin crimping section can be crimped to the outer wire skin. Finally, the outer conductor is crimped to the outside of the shielding ring, and the sections of the shielding ring are pressed against the corresponding parts of the cable by the compression of the outer conductor.
[0050] In order to make the relative fixation between the shielding ring 1 and the shielding layer 204 of the cable 2 more firmly, an anti-retraction structure is also provided on the shielding layer crimping section 103 of the shielding ring 1. An inner anti-retraction structure for pressing and fitting with the shielding layer 204 of the cable 2 is provided on the inner surface of the shielding layer crimping section 103. Figure 3-4 , Figure 7 As shown in , the inner anti-retraction structure is specifically an anti-retraction convex point 108, which is a wedge-shaped protrusion that gradually tilts inward from front to back. Multiple anti-retraction convex points 108 are arranged at intervals, and each anti-retraction convex point 108 is used to press on the shielding layer of the cable, so that the resistance to axial relative movement between the shielding layer crimping section 103 and the shielding layer is greater, and the relative fixation is more firm. The outer surface of the shielding layer crimping section 103 is provided with an outer anti-retraction structure for pressing and matching with the shielding layer attached to the outside of the shielding ring after folding, as shown in FIG. Figure 5-6 As shown in FIG. 1 , the outer anti-recoil structure is specifically an anti-recoil pit 109, and a plurality of anti-recoil pits 109 are regularly arranged on the outer surface of the shielding layer crimping section 103. When processing the anti-recoil pit 109, as shown in FIG. Figure 8-9 As shown in the figure, a diamond-shaped groove is punched out on the outer surface of the shielding layer crimping section 103. When punching, the metal material around the diamond-shaped groove is squeezed outward on the outer surface of the shielding layer crimping section 103 to form small protrusions around the diamond-shaped groove. Several small protrusions are pressed and contacted with the shielding layer attached to the outside of the shielding ring after folding, thereby increasing the resistance of the shielding layer crimping section 103 to the axial relative movement of the cable, achieving a better anti-retreat effect.
[0051] In other embodiments, a plurality of anti-recoil pits may be provided on the inner surface of the crimped section of the shielding layer as an inner anti-recoil structure, and a plurality of convex points may be provided on the outer surface of the crimped section of the shielding layer as an outer anti-recoil structure. Of course, the anti-recoil structure may be provided only on the inner or outer side of the crimped section of the shielding layer. In addition to the structures listed in the above embodiments, the anti-recoil structure may also adopt other structures, for example, welding a plurality of small convex blocks on the inner or outer surface of the crimped section of the shielding layer as an anti-recoil structure.
[0052] When assembling the cable assembly, Fig.10As shown, first peel off a section of the outer sheath 205 at one end of the cable 2 to expose the shielding layer 204, then crimp the shielding ring 1 to the outside of the cable 2, the shielding layer crimping section 103 of the shielding ring 1 is wrapped and crimped on the shielding layer 204 of the cable 2, the sheath crimping section 105 is wrapped and crimped on the outer sheath 205 of the cable 2, then the shielding layer 204 is folded 180° and attached to the outside of the shielding ring 1, and finally the outer conductor 3 is crimped to the outside of the shielding ring 1, the front section 301 of the outer conductor is crimped on the shielding layer 204 attached to the outside of the shielding ring 1 after folding, and the rear section 302 of the outer conductor is crimped on the sheath crimping section 105 of the shielding ring 1 to form an integral cable assembly. The shielding ring 1 is located between the cable 2 and the outer conductor 3, and can play a role in fixing and supporting the shielding layer 204 attached to the outside of the shielding ring 1. The shielding layer 204 attached to the outside of the shielding ring 1 is squeezed by the outer conductor 3 and the shielding ring 1, thereby achieving reliable conduction between the outer conductor 3 and the shielding layer 204 of the cable 2. The wire sheath crimping section 105 of the shielding ring 1 is crimped onto the outer wire sheath 205 of the cable 2, and the outer conductor rear section 302 is crimped onto the outside of the wire sheath crimping section 105, thereby protecting the cable 2 and preventing the outer wire sheath 205 from retreating.
[0053] The outer conductor 3 is a universal standard part. For cables 2 with different wire diameters, a universal outer conductor 3 can be used. It is only necessary to replace different shielding rings 1. The thickness of each segment of the shielding ring 1 can be adjusted according to the wire diameter of the cable 2 to ensure that the thickness of each segment of the shielding ring 1 is sufficient to fill the gap between the cable 2 and the outer conductor 3. During production and manufacturing, it is only necessary to produce multiple sets of shielding rings 1 and one set of outer conductors 3, and develop one set of outer conductor manufacturing molds. Opening one less set of outer conductor manufacturing molds has a huge effect on reducing costs, thereby greatly reducing the cost and management cost of the outer conductor mold. The shielding ring 1 itself is a simple stamping part, with less mold costs, and is simple and quick to manufacture, thereby greatly reducing the manufacturing cost of the cable assembly.
[0054] The utility model further provides an embodiment of a shielding ring, the specific structure of which is the same as the structure of the shielding ring in the embodiment of the cable assembly described above, and will not be described in detail herein.
