Abstract

The invention provides a full-surrounded cable connecting terminal comprising a connecting terminal body. A connection sleeve is manufactured at one end of the connecting terminal body. A connecting hole is manufactured in the connection sleeve. The metal conductive wire of the head part of a cable is inserted in the connecting hole. The full-surrounded cable connecting terminal is characterized in that a large surrounding sleeve is manufactured at the other end of the connection sleeve. A large hole is manufactured in the large surrounding sleeve. The insulating layer, which is close to the metal conductive wire of the head part, of the cable is inserted in the large hole. The aperture of the large hole is greater than that of the connecting hole. The large hole is communicated with the connecting hole. Advantages of the full-surrounded cable connecting terminal are that firstly, the connecting terminal wraps the exposed metal conductive wire and partial insulating layer simultaneously so that existence of a gap at the connection part can be avoided, connection sealing performance is great and rainwater can be prevented from flowing to the metal conductive wire; secondly, tension strength of the connection part of the connecting terminal and the cable is enhanced so that connection is more reliable; and thirdly, the connecting terminal wraps the insulating layer simultaneously so that the insulating layer is connected even the connection part is bent, and thus disconnection of the connection part of the connecting terminal and the cable can be prevented.

Description

Full encirclement cable connecting terminal

Technical field

The present invention relates to binding post, particularly relate to and entirely surround cable connecting terminal.

Background technology

Binding post is to the connector on electric equipment for stube cable electric wire, existing copper and copper aluminum connecting terminal (as shown in Figure 1) structure generally comprise binding post body 1 ', binding post body has the screw hole 2 ' of connecting circuit, binding post other end is shaped with adapter sleeve 3 ', when adapter sleeve is connected with cable or electric wire, need first the insulating barrier 4 ' of Exterior cable to be cut, inner plain conductor 5 ' part is exposed, then the plain conductor exposed is inserted in adapter sleeve, the shortcoming that this structure exists is: one, owing to only plain conductor being inserted in adapter sleeve, insulating barrier is thicker, cannot insert in adapter sleeve, just can cause between adapter sleeve and insulating barrier and there is gap 6 ', the water capacity easily flows into the plain conductor inside cable and insulating barrier from gap, cause and burn binding post, namely adhesive tape is used to encase this gap position, because outdoor, after using a period of time, adhesive tape can scatter automatically, cause the accident hidden danger, two, the adapter sleeve of binding post is only connected with the plain conductor of cable, and the tension intensity of junction is low, and connection reliability is poor, three, because wind is rocked or bending in construction, easily break in the plain conductor junction of binding post and cable.According to power supply administration's reflection, had an accident more than 10% due to binding post and cable junction, accident rate is high.

Summary of the invention

The object of the invention is the shortcoming existed to overcome prior art, provide a kind of and encased together with the insulating barrier near plain conductor by the plain conductor of cable, waterproof seal is good, and junction tension intensity is high, connects and entirely surrounds cable connecting terminal reliably.

The technical scheme that the present invention surrounds cable connecting terminal is entirely: comprise binding post body, one of binding post body is shaped with adapter sleeve, wiring hole is shaped with in adapter sleeve, the plain conductor of cable head inserts in wiring hole, it is characterized in that: described adapter sleeve other end is shaped with and surrounds cover greatly, large encirclement in cover is shaped with macropore, and cable inserts in macropore near the insulating barrier of head metal wire, the aperture of macropore is greater than the aperture of wiring hole, and macropore communicates with wiring hole.

The invention discloses one and entirely surround cable connecting terminal, principal character comprises binding post body, it is shaping that binding post body adopts the conductor material such as copper or aluminium alloy to manufacture, adapter sleeve is shaped with binding post body one, be shaped with at the afterbody of adapter sleeve and surround cover greatly, macropore is shaped with in large encirclement cover, the aperture of macropore is greater than the aperture of wiring hole, when binding post is connected with cable, binding post is inserted together by the plain conductor of cable head and near the partial insulative layer of plain conductor, wherein plain conductor exposed portion is inserted in the wiring hole of adapter sleeve, insulating barrier partial insertion is large to be surrounded in the macropore of cover, again adapter sleeve and the large cover that surrounds are clamped, surround with large plain conductor and the insulating barrier that the hard-pressed bale that is locked lives cable by adapter sleeve, its advantage is: one, binding post encases the plain conductor and partial insulative layer that expose simultaneously, thus avoid occurring that junction exists gap, connection sealing is good, can prevent rainwater from flowing to plain conductor place, two, the tension intensity of binding post and cable junction improves, and connects more reliable, three, because binding post encases insulating barrier simultaneously, even if therefore junction is bent, still have insulating barrier to connect, thus prevent binding post and cable junction from breaking.

The present invention surrounds cable connecting terminal entirely, the wiring hole in described adapter sleeve with greatly surround the macropore junction in overlapping and be connected through inclined-plane or arc surface.Inclined-plane or arc surface play the guiding role, and are conducive to the plain conductor of cable to insert in the wiring hole of adapter sleeve.

Embodiment

The present invention relates to one and entirely surround cable connecting terminal, as shown in Figure 2, comprise binding post body 1, one of binding post body is shaped with adapter sleeve 2, is shaped with wiring hole 3 in adapter sleeve, the plain conductor 7 of cable head inserts in wiring hole, it is characterized in that: described adapter sleeve 2 other end is shaped with large encirclement cover 4, and large encirclement in cover is shaped with macropore 5, and cable inserts in macropore near the insulating barrier 8 of head metal wire 7, the aperture of macropore is greater than the aperture of wiring hole 3, and macropore communicates with wiring hole.Principal character comprises binding post body 1, it is shaping that binding post body adopts the conductor material such as copper or aluminium alloy to manufacture, adapter sleeve 2 is shaped with binding post body one, large encirclement cover 4 is shaped with at the afterbody of adapter sleeve, macropore 5 is shaped with in large encirclement cover, the aperture of macropore is greater than the aperture of wiring hole 3, when binding post is connected with cable, binding post is inserted together by the plain conductor 7 of cable head and near the partial insulative layer 8 of plain conductor, wherein plain conductor 7 exposed portion is inserted in the wiring hole 3 of adapter sleeve 2, in the macropore 5 of the large encirclement cover 4 of insulating barrier 8 partial insertion, again adapter sleeve and the large cover that surrounds are clamped, plain conductor 7 and the insulating barrier 8 of cable is tightly encased by adapter sleeve 2 and large encirclement cover 4, its advantage is: one, binding post encases the plain conductor and partial insulative layer that expose simultaneously, thus avoid occurring that junction exists gap, connection sealing is good, can prevent rainwater from flowing to plain conductor place, two, the tension intensity of binding post and cable junction improves, and connects more reliable, three, because binding post encases insulating barrier 8 simultaneously, even if therefore junction is bent, still have insulating barrier to connect, thus prevent binding post and cable junction from breaking.Wiring hole 3 in described adapter sleeve 2 is connected through inclined-plane 6 or arc surface with large macropore 5 junction surrounded in cover 4.Inclined-plane 6 or arc surface play the guiding role, and are conducive to the plain conductor 7 of cable to insert in the wiring hole 3 of adapter sleeve 2.
