Fig. 2-5A illustrate a cable connector assembly 10 and its constituent components according to an exemplary embodiment of the present utility model.

Referring to fig. 2-3B, the cable connector assembly 10 includes a cable connector 100 and a ground anchor 200. The cable connector 100 includes an insulative connector body 102 and an outer shield layer 104 disposed on an outer surface of the connector body 102. The ground anchor 200 is adapted to encircle the cable connector 100 and to be secured to the cable connector 100 such that the ground anchor 200 contacts the outer shield 104. The cable connector 100 includes a detent 106, the detent 106 being disposed at the outer shield 104 and configured to receive at least a portion of the ground anchor 200 and position the ground anchor 200 relative to the cable connector 100.

Through setting up constant head tank 106, can carry out accurate location to ground anchor ear 200 when installation ground anchor ear 200, avoid ground anchor ear 200 crooked for cable connector 100 for the internal surface of ground anchor ear 200 can contact with cable connector 100's outer shielding layer 104 better after ground anchor ear 200 screws up, and then guarantees sufficient ground area and good earthing effect.

Referring to fig. 3A to 4, the cable connector 100 includes an insulating and hollow connector body 102, an outer shielding layer 104 formed on an outer surface of the connector body 102, and an inner semiconductive layer 108 formed on an inner surface of the connector body 102. The connector body 102 may be made of an insulating material, such as insulating rubber. The outer shield layer 104 and the inner semiconductive layer 108 may be made of, for example, conductive rubber. The connector body 102, the outer shield layer 104, and the inner semiconductive layer 108 may be integrally formed.

In the illustrated embodiment, the connector body 102 includes a hollow transverse section 110 and a hollow longitudinal section 112. The transverse section 110 is for receiving a bushing of an electrical switching apparatus. The longitudinal section 112 extends perpendicularly from the transverse section 110 and is adapted to receive a connecting end of a cable. The bushing of the electrical switching apparatus and the connection end of the cable may be electrically connected to each other inside the cable connector 100. The detent 106 is disposed at a portion of the outer shield layer 104 that is located at an outer surface of the longitudinal section 112 and is configured to limit movement of the ground anchor 200 relative to the longitudinal section 112 in the longitudinal direction L of the longitudinal section 112.

Referring to fig. 5A, in the illustrated embodiment, a ground anchor 200 is used to electrically connect the outer shield 104 of the cable connector 100 with the ground wire 20, thereby achieving grounding of the outer shield 104 of the cable connector 100. The ground anchor 200 may be made of a metallic material. Ground anchor 200 may include an anchor body 202, a first fastening tab 204, and a second fastening tab 206. The hoop body 202 has a non-closed annular shape and has opposite first and second ends 208, 210. The staple body 202 may encircle and pinch the longitudinal section 112 of the cable connector 100, thereby securing the ground staple 200 to the cable connector 100. It will be appreciated that in other embodiments, the body of the anchor ear may comprise two semi-annular portions which enclose and grip a longitudinal section of the cable connector.

In the illustrated implementation, first and second fastening lugs 204, 206 extend from first and second ends 208, 210, respectively, of the staple body 202, and the first and second fastening lugs 204, 206 are opposite one another. Ground anchor 200 may also include an externally threaded fastener 212 and a nut 214. The first and second fastening lugs 204 and 206 may include first and second fastening holes (not shown), respectively, for the externally threaded fasteners 212 to pass through to be fastened to one another by the externally threaded fasteners 212 and nuts 214. The externally threaded fastener 212 may be, for example, a bolt or stud, or the like.

Referring to fig. 2-4, in the illustrated embodiment, the cable connector 100 includes first and second positioning ribs 114, 116, the first and second positioning ribs 114, 116 protruding outwardly from the outer shield layer 104 and being spaced apart from each other in the longitudinal direction L of the longitudinal section 112. The first and second locating ribs 114, 116 cooperate with the outer shield layer 104 to define locating slots 106 for receiving and locating the ground anchor 200 (and more specifically, anchor body 202). In the illustrated embodiment, the central axis of ground anchor 200 coincides with the longitudinal axis of longitudinal section 112 when anchor body 202 is positioned in detent 106. Optionally, a dimension S1 of the staple body 202 in the longitudinal direction L of the longitudinal section 112 is approximately equal to a dimension S2 of the locating groove 106 in the longitudinal direction L of the longitudinal section 112 (i.e., the spacing of the first locating rib 114 and the second locating rib 116 in the longitudinal direction L of the longitudinal section 112) such that the ground staple 200 can be stably positioned on the cable connector 100. It will be appreciated that in other embodiments, where the outer shield is thicker, for example, a locating slot recessed relative to the outer surface of the outer shield may also be provided directly on the outer shield to receive and locate the ground anchor.

In the illustrated embodiment, the first positioning rib 114 and the second positioning rib 116 extend continuously in the circumferential direction of the longitudinal section 112 to have an annular shape. It will be appreciated that in other embodiments, the first and/or second locating ribs may comprise a plurality of locating portions spaced apart along the circumferential direction of the longitudinal section. Alternatively, the first positioning rib 114 and the second positioning rib 116 may be integrally formed with the outer shielding layer 104 of the same material to simplify the manufacturing process of the cable connector 100.

With continued reference to fig. 2-4, in the illustrated embodiment, the cable connector 100 includes a ground lug 118 that protrudes outwardly from the outer shield 104. The ground lugs 118 may be integrally formed with the outer shield 104 from the same material. The ground lugs 118 are adapted to be clamped between the first and second fastening lugs 204, 206 when the first and second fastening lugs 204, 206 are fastened to each other. In this manner, additional ground area/conductive paths may be provided by contact between the first and second fastening lugs 204, 206 and the ground lugs 118, thereby achieving a better ground effect. This is particularly advantageous in situations where poor contact between the hoop body 202 and the outer shield 104 is caused, for example, by thermal expansion and contraction.

Referring to fig. 2, 3B, 5A and 5B, for the illustrated embodiment, ground wire 20 may be connected to ground anchor 200 by externally threaded fasteners 212 and nuts 214 while ground anchor 200 is secured to cable connector 100, thereby grounding outer shield 104 of cable connector 100 through ground anchor 200 and ground wire 20. In the illustrated embodiment, the ground lug 118 has a third fastening hole 120 and the ground wire 20 includes a connecting end 22 with a fourth fastening hole 24 at the connecting end 22. The external threaded fastener 212 may be threaded through the first fastening hole of the first fastening lug 204, the second fastening hole of the second fastening lug 206, the third fastening hole 120 of the ground lug 118, and the fourth fastening hole 24 of the ground wire 20 to enable the cable connector 100, the ground anchor 200, and the ground wire 20 to be fastened to one another, thereby enabling the outer shield 104 of the cable connector 100 to be grounded.

For example, when installing ground anchor 200, anchor body 202 may be snapped into detent 106 such that ground lugs 118 are sandwiched between first and second fastening lugs 204, 206. Then, the connecting end 22 of the ground wire 20 is fitted to the side of the first or second fastening lugs 204 or 206 facing away from the ground lug 118, or the connecting end 22 of the ground wire 20 is also sandwiched between the first and second fastening lugs 204 and 206, and the first, second, third, and fourth fastening holes 120 and 24 are aligned with each other. Next, the external screw fastener 212 is passed through the first, second, third and fourth fastening holes 120, 24, and the nut 214 is tightened, so that the cable connector 100, the ground anchor 200 and the ground wire 20 are fastened to each other.

Due to the positioning groove 106, when the anchor ear body 202 is clamped into the positioning groove 106, the anchor ear body 202 can be accurately positioned in the positioning groove 106 so that the central axis of the grounding anchor ear 200 coincides with the longitudinal axis of the longitudinal section 112 of the cable connector 100, and thus the inner surface of the anchor ear body 202 facing the cable connector 100 can be tightly contacted with the outer shielding layer 104 when the grounding anchor ear 200 is further tightly fixed so as to ensure that a sufficient grounding area exists between the grounding anchor ear 200 and the outer shielding layer 104, thereby realizing good grounding. At the same time, as described above, the contact between the first and second fastening tabs 204, 206 and the grounding tab 118 may also provide additional grounding area, thereby achieving a better grounding effect.

It should also be appreciated that the various components and features described herein may be made from a variety of materials including, but not limited to, polymers, rubbers, metals, and the like, as well as other suitable materials or combinations of materials known to those skilled in the art.
