In-line grounding adapter

The present invention relates to a technical field of grounding adapters for grounding operations of pavilion switch boxes, and more particularly to an in-line grounding adapter having the advantages of simple structure, small size, and convenient carrying and use.

Referring to Figures 1 and 2, it is pointed out that when the pavilion switch box 10 or the underground cable 11 connected thereto is repaired, the cable joints 110 at both ends of the underground cable 11 are grounded separately. It ensures the safety of maintenance work. When the pavilion switch box 10 and the underground cable line 11 therein are grounded, the cable connector 110 does not need to be removed from the switch box connector 100, but directly connects the connector cover 112 at the rear end of the cable connector 110. Unscrewed and removed, and then the adapter 120 of one end of the conventional grounding connector 12 is inserted into the slot 113 at the rear end of the cable connector 110, and then the tap 130 of one end of the sub-wiring 13 is sleeved. The adapter 120 on the other end of the conventional grounding connector 12 is configured to electrically connect the cable connector 110 to the tap 130 through the conventional grounding connector 12, and finally to extend the ends of an extension line 14. The conductive clips 140 are respectively disposed on the conductive rods 131 at the other end of the branching wires 13 and on the switch box joint holders 101 partially embedded in one of the underground metal grounding objects or the pavilion switch box 10, and further Achieving the connection of the cable connector 110 It is grounded to the metal grounding object or the switch box joint holder 101 to reach the grounding state.

However, the conventional grounding connector 12 has two adapters 120 respectively located at the two ends for respectively connecting the cable connector 110 and the tapping 130 and forming an electrical connection, so the opposite one is The structure is complex and the production cost is high, and its volume is also large and difficult to carry. In particular, when the grounding operation is performed by using the conventional grounding adapter 12, it is necessary to supplement the components such as the sub-wiring 13 and the extension wire 14 to make the cable connector 110 reach the grounding purpose, so the system is very useful. Trouble, complexity and inconvenience. In particular, each time a booth-type switch box 10 is grounded, the conventional grounding adapter 12, the sub-wiring 13 and the extension line 14 are required to perform grounding operations, wherein the conventional grounding is performed. The adapter 12 and the sub-wiring 13 occupy a considerable volume, so it is very inconvenient to carry the system, and the grounding operation is troubled.

The conventional grounding adapter has many problems such as complicated structure, large volume, need to be supplemented with more accessories during use, and inconvenient to carry and use.

This creation provides a plug-in grounding adapter that includes a body and a ground terminal. The seat system is made of an insulating material and includes a bump, a set of joints protruding from one side of the bump, and a through hole penetrating to one of the two end faces. The socket is tapered and can be inserted into a slot at the rear end of a cable connector. The grounding terminal is made of a conductive material and has a combined end and a grounded end. The bonding end is coupled to the through hole and has a screw hole on the end surface for the electrical connection in the slot of the cable connector The sub-spirals are connected to form an electrical connection. The ground end protrudes from a length of the end surface of the bump to form a grounding section for sandwiching a conductive clip at one end of the extension line, so as to be sandwiched between the conductive clip at the other end of the extension line and partially buried in the ground. The metal grounded object forms a grounding effect.

The in-line grounding adapter provided by the present invention can be socketed with the cable connector by the socket of the base body, and then the cable connector and the extension wire are connected by a grounding terminal coupled to the base body. The electrical connection is formed to generate a grounding effect, so that the structure is simpler than the conventional one, and the manufacturing cost is relatively low, and the volume thereof is smaller than that of the conventional one, so that it is less space-consuming and easy to carry. In particular, it is only necessary to cooperate with an extension line to ground the booth switch box and the underground cable line therein, so that it is convenient to carry the upper system, and the use is also relatively simple and easy.

Referring to Figures 3-8, the in-line grounding connector A of the present invention includes a body 20, a grounding terminal 30 and a cover 40. The seat body 20 is made of an insulating material, and includes a circular one-piece bump 21, a set of connecting portions 22 protruding from one side of the protruding block 21, and a through hole 23 penetrating to one end surface. The sleeve portion 22 has a tapered shape and an outer diameter smaller than the protrusion 21, and is insertable into the slot 113 at the rear end of a cable joint 110. The through hole 23 is formed with an opening groove 24 having a larger outer diameter at the opposite end of the projection 21.

The coupling end 31 is coupled to the through hole 23, and the end portion has a larger outer diameter convex portion 33 for being embedded in the opening groove 24. The end surface of the convex portion 33 has a screw hole 34 for the cable. The electrical terminals 111 in the slots 113 of the connector 110 are screwed to form an electrical connection. The grounding end 30 protrudes from the end surface of the bump 21 to form a grounding section 35. The grounding section 35 has a plurality of cross embossings on the circumferential surface and two clamping planes 36 on opposite sides. The plurality of cross embossings can be clamped by the conductive clips 140 of an extension line 14 and are not easily slipped. The two clamping planes 36 can be clamped by a tool such as a wrench to apply force to rotate them.

The cover 40 is made of an insulating material, and has a receiving groove 41 at one end for receiving the grounding portion 35 of the grounding terminal 30, so that the grounding terminal 30 can be protected when the in-line grounding connector A is not in use. .

Please refer to the figures 5~8, which indicates that the cable joint 110 does not need to be removed from the switch box joint 100 when the grounding operation is performed. Instead, the connector cover 112 at the rear end of the cable connector 110 is directly unscrewed, and then the socket portion 22 of the base 20 of the in-line grounding connector A of the present invention is inserted into the cable connector 110. In the slot 113 of the end, the screw hole 34 of the grounding terminal 30 is screwed to the electrical terminal 111 of the cable connector 110 to form an electrical connection, and then the cover 40 is connected to the in-line grounding connector. The grounding terminal 30 of A is removed (as shown in Figures 3 and 4), and finally the conductive clips 140 at both ends of an extension line 14 are respectively clamped to the grounding terminal 30 of the in-line grounding connector A. The section 35 is mounted on a switch box joint holder 101 partially embedded in one of the underground metal grounding objects or the pavilion switch box 10. In this way, the cable joint 110 can be connected to the metal grounding object or the switch box joint holder 101 to form a grounding state.

The in-line grounding connector A provided by the present invention can be sleeved with the cable connector 110 by the socket portion 22 of the base body 20, and then the grounding terminal 30 coupled to the base body 20 is used to make the The cable connector 110 is electrically connected to the extension wire 14 to generate a grounding effect, so that the structure is simple and the manufacturing cost is relatively low, and in particular, the volume thereof is small, so that the space is relatively small and easy to carry. In particular, it is only necessary to cooperate with an extension line 14 to ground the booth switch box 10 and the underground cable line 11 therein. Therefore, it is convenient to carry the upper system, and the use is also relatively simple and easy.
