At the connecting elements of in the past electric conductor binding post, referring to shown in Figure 1, the lead connector is provided with installs the conductor mounting hole, is provided with a screwed hole perpendicular to this installing hole on the sidewall of lead connector, and screw passes this screwed hole lead is clamped; Referring to shown in Figure 2.Owing to adopted this screw type end, screw directly contacts with lead, in the process of tighten the screws, drives lead and rotates together, easily lead is fractureed, and contact is also often not really abundant between lead and the installing hole, easily causes loose contact.For addressing the above problem, a wire-protecting plate need be set in case when tightening terminal screw screw damage the lead that will connect.Patent of invention 99101775.7 discloses a kind of connecting elements that has screw terminal; referring to shown in Figure 3; its structure is to be provided with a wire-protecting plate between the end of conductor and conductor; this baffle is " L " shape; this structure in use because when a side of connecting elements screws tight screw, the wire-protecting plate can move up; move up thereby drive lead, make between lead and the installing hole and cause loose contact.
Summary of the invention
The purpose of this utility model provides and a kind ofly can make the binding post that has the good thread terminal line ball that contacts between lead and the installing hole.
The technical scheme that the utility model adopted is: a kind of binding post of thread terminal line ball; comprise a wire connector 2; be provided with installing hole 21 above the connector at this; the side is provided with a screwed hole 22 perpendicular to this installing hole 21; lead 3 can insert in the top installing hole 21; and pass through lead 3 to be clamped perpendicular to the screwed hole 22 of this installing hole 21; between the end of lead and lead, be provided with a wire-protecting plate 1 at installing hole 21 inner bolts; described wire-protecting plate 1 comprises following base plate 11 and the wing plate 12 that links to each other with base plate rear end; it is characterized in that: the front end of described base plate 11 is provided with tip-tilted location-plate 13, and the other end of described location-plate 13 is a reversed acanthoid.
The both sides of described base plate 11 are provided with the side plate 14 of reversed acanthoid.
Described side plate 14 is tip-tilted structure.
Described side plate 14 is concordant with base plate 11.
Described wing plate 12 comprises the reinforcing section 121 of a projection, is round-corner transition 15 between wing plate 12 and the base plate 11.
The upper end of described wing plate 12 is an outwardly-bent structure.
The utility model has the advantages that; simple in structure, cost is low; in use, this wire-protecting plate 1 can be put into the installing hole 21 of conductor easily, is easy to fix with screw by screwed hole; because of location-plate 13 is tip-tilted structure; when with screw during to wing plate 12 application of forces, according to the action principle of power, the thorn-like side on the location-plate 13 tightly inserts in the wall of installing hole 21; base plate 11 is abutted against on the conductor, and the lead 3 on the base plate 11 can not produce and move and the play phenomenon.

Embodiment
Below in conjunction with accompanying drawing, the utility model is carried out concrete description: a kind of binding post of thread terminal line ball, comprise a wire connector 2, be provided with an installing hole 21, described installing hole 21 is a blind hole, be provided with a screwed hole 22 perpendicular to these installing hole 21 extensions in the side of wire connector 2, lead 3 can insert in the top installing hole 21, and by lead 3 being clamped, between the end of lead and lead 3, be provided with a wire-protecting plate 1 at installing hole 21 inner bolts perpendicular to the screwed hole 22 of this installing hole 21; Referring to Fig. 4, Fig. 5.
The structure of wire-protecting plate 1, referring to shown in Figure 6, this wire-protecting plate 1 comprises following base plate 11, the wing plate 12 and the location-plate 13 that link to each other with the rear end of base plate 11, is provided with tip-tilted location-plate 13 at the front end of base plate 11.The upper end of described location-plate 13 is a reversed acanthoid, plays the effect of fixing cord baffle 1.Be provided with the side plate 14 of reversed acanthoid in the both sides of described base plate 11, side plate 14 can be tip-tilted structure, also can be the structure concordant with base plate 11.Can well be fixed on wire-protecting plate 1 in the sidewall of installing hole 21 like this.
