The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, and terminal connector is provided, and solves the existing connector for lightning arrester and earth connection, connects illusive defect.
The purpose of this utility model is achieved through the following technical solutions: terminal connector, comprise two metal intermediate plates, on two intermediate plates, be all respectively arranged with the wire casing that twice are parallel to each other, twice wire casing on each intermediate plate is arranged on same end face, described wire casing runs through corresponding intermediate plate on its bearing of trend, wire casing on two intermediate plates is corresponding one by one, two intermediate plates are connected and fixed by clamping device, when two intermediate plates connect, the end face that intermediate plate is provided with wire casing is just arranging the end face of wire casing to another intermediate plate, on described wire casing inner surface, be covered with and have sharp-pointed projection.Fixing between the lead-in wire of lightning arrester and earth connection of this device, lead-in wire and earth connection stagger and are placed on respectively in the twice wire casing of an intermediate plate, then another intermediate plate is covered on the intermediate plate that is placed with electric wire, then fix with clamping device, two intermediate plates can clamp lead-in wire and earth connection, so very time saving and energy saving.Core in lead-in wire and earth connection is to be all twisted into metal wire, between can leave gap, the projection arranging in wire casing is stuck in these gaps, make to go between and earth connection between connection more reliable.
Further, aluminium projection is set between above-mentioned projection, the height of aluminium projection is higher than projection, aluminium projection quality is softer, in long-time compressing, can be filled in projection, makes connector can compress lead-in wire and earth connection, and the electric conductivity of aluminium will get well, increase conductivity.
Further, above-mentioned clamping device comprises at least two screw rods, all screw rods run through respectively two intermediate plates perpendicular to wire casing, on the termination of screw rod, be connected with nut, two screw rods run through two intermediate plates, ensure that intermediate plate can not twist, then on termination, screwed with nut, ensured that two intermediate plates can clamp lead-in wire and earth connection.
Further, above-mentioned all screw rods are in the same plane, and two wire casings on same intermediate plate are with screw rod place plane symmetry, and screw rod is positioned at the center of wire casing, ensured that lead-in wire and earth connection compress effect consistent, there will not be a line tight, a line pine.
Further, above-mentioned intermediate plate adopts iron and steel to make, and when ensureing conductivity, has also ensured to be pulled off intensity.
Further, on above-mentioned intermediate plate, be provided with reinforcement, the bearing of trend of reinforcement is consistent with the bearing of trend of wire casing, has strengthened intermediate plate in the intensity of direction that is stretched, and avoids occurring the phenomenon being pulled off.
The beneficial effects of the utility model are: this device has facilitated the lead-in wire of lightning arrester and being connected of earth connection, and very convenient use is time saving and energy saving, has accelerated operating efficiency, and projection is set in wire casing, block lead-in wire and earth connection, have ensured connection effect.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but structure of the present utility model is not limited only to following examples:
[embodiment 1]
As Figure 1-4, terminal connector, comprise two metal intermediate plates 1, on two intermediate plates 1, be all respectively arranged with the wire casing 2 that twice are parallel to each other, twice wire casing 2 on each intermediate plate 1 is arranged on same end face, described wire casing 2 runs through corresponding intermediate plate 1 on its bearing of trend, wire casing 2 on two intermediate plates 1 is corresponding one by one, two intermediate plates 1 are connected and fixed by clamping device 3, when two intermediate plates 1 connect, the end face that intermediate plate 1 is provided with wire casing 2 is just arranging the end face of wire casing 2 to another intermediate plate 1, on described wire casing 2 inner surfaces, be covered with and have sharp-pointed projection 8.In the present embodiment, clamping device 3 comprises at least two screw rods 4, all screw rods 4 run through respectively two intermediate plates 1 perpendicular to wire casing 2, on the termination of screw rod 4, be connected with nut 5, two screw rods 4 run through two intermediate plates 1, ensure that intermediate plate 1 can not twist, screw on termination with nut 5 again, ensured that two intermediate plates 1 can clamp lead-in wire and earth connection.All screw rods 4 are in the same plane, and two wire casings 2 on same intermediate plate 1 are with screw rod 4 place plane symmetry, and screw rod 4 is positioned at the center of wire casing 2, ensured that lead-in wire and earth connection compress effect consistent, there will not be a line tight, a line pine.Fixing between the lead-in wire of lightning arrester and earth connection of this device, lead-in wire and earth connection stagger and are placed on respectively in the twice wire casing 2 of an intermediate plate 1, then another intermediate plate 1 is covered on the intermediate plate 1 that is placed with electric wire, then fix with clamping device, two intermediate plates 1 can clamp lead-in wire and earth connection, so very time saving and energy saving, core in lead-in wire and earth connection is to be all twisted into metal wire, between can leave gap, the projection 8 arranging in wire casing is stuck in these gaps, makes the connection between lead-in wire and earth connection more reliable.
