DETAILED DESCRIPTION

(8) Referring to FIG. 1, a small-sized right-angled elbow conductor connector 1 for high-frequency RF signal transmission is shown. The right-angled elbow conductor connector 1 comprises: a right-angled shell body, the body comprising a first leg 2 of the right angle, a second leg 3 perpendicular to the first leg 2 and a cylindrical part 4 mounted on the second leg 3, the cylindrical part 4 is made of a conductive material, for example a brass; a first conductor 5 mounted in the first leg 2 of the right-angled shell body, the first conductor 5 is made of a conductive material, for example a brass; and an end cap 14, for enveloping an end of the first leg 2. The first leg 2 and the second leg 3 are each made of a conductive material (for example a brass) and can he formed integrally or assembled from two parts. The second leg 3 and the cylindrical part 4 arc mounted by crimping, thereby they can connected with an outer conductor of a cable. For example, the second leg 3 has outer convex teeth 21, and the outer conductor of the cable 7 (see FIG. 3, 4) is crimped between the cooperating inner side of the cylindrical part 4 and the convex teeth 21 on the second leg 3, such that the outer conductor of the cable and the second leg of the connector are reliably connected. An inner conductor of the cable 7 or a second conductor 6 (see FIG. 3, 4) is inserted in the first conductor 5, such that the inner conductor of the cable and the inner conductor of the connector are reliably connected, as will be described in detail hereinbelow. An insulator is arranged between the first conductor 5 and an inner wall of the first leg 2.

(9) Referring to FIG. 2, a perspective view of the first conductor 5 of the right-angled elbow conductor connector 1 is shown. The elongate first conductor 5 has a longitudinal axis A and the first conductor 5 at an end thereof has a first hole 8 with an axis perpendicular to the axis A, such that the second conductor 6 is able to be inserted in the first hole 8 perpendicular to the axis A. A first slot 10 is slotted at this end of the first conductor 5 along the axis A, and the first slot 10 is communicated with the first hole 8, such that this end of the first conductor is divided into a first half 11 and a second half 12, so as to be able to elastically clamp the second conductor 6 when the second conductor 6 is inserted in it. The first hole 8 is a function hole for clamping.

(10) Still referring to FIG. 2, the first conductor 5 also has a second slot 13 disposed along the axis A, and the second slot 13 is also communicated with the first hole 8 and is positioned on a side of the first hole 8 diametrically opposite to the first slot 10. A second hole 9 is arranged at the other end of the second slot 13 opposite to the end where the second slot is communicated with the first hole 8, the axis of the second hole 9 is parallel with the axis of the first hole 8, and a diameter of the second hole is larger than a width of the second slot 13 but smaller than the diameter of the first hole 8, as shown in the left one in FIG. 2. It can also be envisioned that the diameter of the second hole 9 is equal to or even larger than the diameter of the first hole. The second hole 9 is an auxiliary hole, the function of which will be described hereinbelow.

(11) As an alternative, the diameter of the second hole 9 may be equal to the width of the second slot 13, as shown in the right one in FIG. 2.

(12) The diameter of the first hole 8 may be smaller than a diameter of the second conductor 6, and the slot 10 is aequilate along the axis A-A, thus the first slot 10 is able to be spreaded out when the second conductor 6 is inserted in the first hole 8, and then elastically clamps the second conductor 6 between the first half 11 and the second half 12 by virtue of the elasticity of the material itself. Alternatively, the diameter of the first hole 8 is equal to or even larger than the diameter of the second conductor 6, and the first half 11 and the second half 12 are squeezed with a tool (for example a press or a molding tool) after the first slot 10 is slotted, then after aging treatment, the first conductor plastically deforms at the base of the second hole 9, thus the widths of the first slot 10 and the second slot 13 taper towards the end of the first conductor, and the diameter of the first hole 8 becomes smaller, thereby a great elastic force for clamping the second conductor 6 is obtained.

(13) Next the insertion process of the inner conductor 6 of the cable 7 is illustrated with reference to FIGS. 3 and 4. As shown in FIG. 3, the cable 7 comprises the inner conductor 6, the inner conductor 6 is inserted in the second leg 3 along a direction perpendicular to the axis A, aligned with the first hole 8 at the end of the first conductor 5 in the first leg 2, and then is inserted in the first hole 8, when the right-angled elbow conductor connector of the utility model is connected with the cable 7, as shown in FIG. 3. Thus, the slot 10 is spread out slightly and then elastically springs back because of the property of the material itself, thus the inner conductor 6 is elastically clamped between the first half 11 and the second half 12, such that the inner conductor 6 and the first conductor 5 are reliably electrically connected. Due to the presence of the second hole 9, a stress concentration caused by the insertion of the second conductor 6 is avoided, meanwhile the inner conductor 6 can be inserted in the first hole 8 quite easily, and the elastic clamping force for the inner conductor is improved.

(14) The right-angled elbow conductor connector of the utility model has an auxiliary hole for dispersing stress and a function hole for grasping and connecting the inner conductor of the cable, which holes are arranged in parallel. The double-hole right-angled elbow conductor connector is particularly suitable for connecting the small-sized cables, for example the Cinta series cables produced by CommScope Corp.

(15) Next a second embodiment of the right-angled elbow conductor connector will be described with reference to FIG. 5 and FIG. 6.

(16) Referring to FIG. 5, a elongate first conductor 15 having an axis A is made of a conductive material, and has a hollow portion 17, the hollow portion 17 has at least two bending ribs 18, 19 and a hollow space 20 between the two bending ribs, the hollow portion 17 is connected with remaining portions of the first conductor body 15 through the at least two bending ribs 18, 19, and an outer periphery of the at least two bending ribs defines a maximum radial dimension D in a plane perpendicular to the axis A.

(17) A second conductor 16 has a hole 21, a diameter of the hole 21 is slightly smaller than the maximum radial dimension D, such that the bending ribs 18, 19 deform elastically when the hollow portion 17 of the first conductor 15 is inserted in the hole 21 of the second conductor, and the first conductor 15 is elastically retained in the second conductor 16 by virtue of the elasticity of the material itself, thereby the reliable electrical connection between the first conductor 15 and the second conductor 16 is achieved.

(18) In addition, although the particular features of the utility model have been described with respect to only one or more of several exemplary embodiments, such features can be combined with one or more features of other embodiments, if such features are desirable or advantageous for any given or particular application.
