Abstract

The utility model relates to a wiring terminal for an AC contactor, which belongs to an electrical connector element; one end of the wiring terminal is provided with a contact and the other end thereof is provided with a terminal block, a screw hole is machined on the terminal block, a conductor hole is also machined on the terminal block, the conductor hole perpendicularly intersects with the screw hole, the conductor hole is a through hole, and a screw is in threaded connection with the terminal block. When in use, a conductor wire penetrates through the conductor hole, the screw is screwed to tighten the conductor wire, so the conductor wire is firmly connected with the terminal block, and the conductor wire is safe in use and is not easy to burn out; as a wire clip is avoided, the wiring terminal has low cost and can be used repeatedly.

Description

The binding post of A.C. contactor

One, technical field:

The utility model relates to electric connecting element, what be specifically related to is the binding post of A.C. contactor.

Two, background technology:

The binding post of A.C. contactor is parts of A.C. contactor, is used for A.C. contactor and lead are coupled together, and every A.C. contactor has six binding posts.The binding post of normally used A.C. contactor is flat binding post, as shown in Figure 1.One end of flat binding post is contact 1, and the other end is terminals 2, on the terminals 2 screw is arranged, and screw 3 is threaded with terminals 2, by screwing screw 3 lead is pressed between screw 3 and the terminals 2.Often become flexible but connect between back lead and the terminals 2 like this, cause binding post to be burnt, the device damage that can be connected with A.C. contactor when serious because of loose contact.In order to address this problem, the normal terminal that uses one one end to have fixing hole in real work, one end is the line nose of hollow spool for the centre, the terminals of the terminal of line nose and binding post are fastening by screw, lead is inserted in the spool of line nose, with Crimping Pliers spool is flattened again and tighten up lead.But this method is brought following problem again: one, since the line nose can be connected with lead fixed after must flattening, so the material of line nose is made in requirement must be softer, as with red copper or aluminium, and every A.C. contactor has six binding posts, need be used six line noses, cause use cost higher.Two, because the quilt flattening of used line nose can not resile, can not use repeatedly again, cause very big waste again accordingly.Three, because A.C. contactor is installed in the case more, six line noses of increase have increased installing space undoubtedly again.

Three, summary of the invention:

The purpose of this utility model provides a kind of binding post of A.C. contactor, and the binding post of this A.C. contactor is used to solve former in terminal and unstable problem of being connected of lead.

The technical scheme that its technical problem that solves the utility model adopts is: binding post one end of this A.C. contactor has the contact, the other end is a terminal base, screw is arranged on the terminal base, also has the horizontal wire hole on the terminal base, wire guide and screw intersect vertically, wire guide is a through hole, and screw is threaded with terminal base.

In the wire guide of such scheme, be positioned at the position installation arc pad that wire guide and screw intersect vertically, arc pad and wire guide adapt.

There is decorative pattern arc pad bottom surface in the such scheme.

Beneficial effect:

When 1, the utility model uses, lead is passed wire guide, tighten the screws, screw are about to lead and compress, and compress back lead and terminal base and are connected firmly, and be safe in utilization, is difficult for burning; Need not to adopt the line nose in addition, use cost is low, can use repeatedly.

2, the decorative pattern of the utility model wire guide arc pad bottom surface can not only prevent that lead from sustaining damage, and can also increase the contact area with lead, makes lead more firm with being connected of terminal base.

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is a vertical view of the present utility model;

Fig. 4 is an end view of the present utility model.

1 contact, 2 terminals, 3 screws, 4 pads, 5 wire guides, 6 terminal bases

Five, embodiment:

Fig. 2 is a structural representation of the present utility model, and Fig. 3 is a vertical view of the present utility model, and Fig. 4 is an end view of the present utility model, in conjunction with Fig. 2, Fig. 3, shown in Figure 4, binding post one end of this A.C. contactor has contact 1, and the other end is a terminal base 6, and the vertical direction of terminal base 6 has screw, screw 3 is threaded with terminal base 6, the horizontal direction of terminal base 6 also has wire guide 5, and wire guide 5 is a through hole, and screw is last, wire guide 5 is following, and wire guide 5 intersects vertically with screw; At the position that wire guide 5 and screw intersect vertically arc pad 4 is installed, it is the upper end that arc pad 4 is installed in wire guide 5, the radian of arc pad 4 and the radian of wire guide adapt, there is decorative pattern arc pad 4 bottom surfaces, the decorative pattern of arc pad 4 bottom surfaces can not only prevent that lead from sustaining damage, can also increase the contact area with lead, arc pad 4 is a conductor.

When the utility model uses, lead is passed wire guide 5, tighten the screws 3, compacted at the pressure lower wire of screw 3, compress back lead and terminal base 6 and be connected firmly, safe in utilization, be difficult for burning; Need not to adopt the line nose in addition, use cost is low, can use repeatedly.
