Abstract
The utility model relates to a plug-type cable connector, which comprises a cable core wire crimping part, a conductive contact mounting surface and a connection supporting transition section. The plug-type cable connector is characterized in that the conductive contact mounting surface is divided into a conductive contact mounting surface I and a conductive contact mounting surface II; the interval between the conductive contact mounting surface I and the conductive contact mounting surface II is matched with a component lug to be connected; the component lug is plugged between the conductive contact mounting surface I and the conductive contact mounting surface II; and the conductive contact mounting surface I, the component lug and the conductive contact mounting surface II are fixedly connected via connection bolts. As two conductive contact mounting surfaces are adopted to be contacted with the component lug, the conductive contact area is doubled, the current-carrying area of the contact part is increased, the contact resistance is reduced, and radiation at the connection position is improved; and even in the case of vibration, one conductive contact mounting surface can be ensured to be contacted with the component lug, and then generation of electric arcs can be avoided.
Description
Technical field
The utility model relates to a kind of cable joint, relates in particular to a kind of slotting formula cable joint.
Background technology
The large scale cable is connected the cable joint of usefulness with main circuit electric elements lug plates such as transformer, reactor, circuit breaker, contactors, that generally uses at present mostly is greatly single face contact joint, as shown in Figure 1, it comprises cable core crimping position 1, conductive contact installed surface 3, conductive contact installed surface are connected 2 three positions of supporting changeover portion with cable core crimping position.Its conductive contact installed surface 3 is the single face contact, and during installation: the conductive contact installed surface 3 that will press the cable core joint directly is fixed together with bolt assembly and components and parts lug plate 6.After work a period of time, because vibration and the weight of cable own causes between bolt looseness or conductive contact installed surface 3 and the components and parts lug plate 6 producing and be out of shape from but occur the gap between the contact-making surface, and cause electric arc to burn.The supporting changeover portion 2 that is connected between conductive contact installed surface 3 and the cable core crimping position 1 is flat structure, frangibility under Vibration Condition.
The utility model content
The purpose of this utility model is to overcome above defective, and a kind of firm slotting formula cable joint that connects is provided.
The technical solution of the utility model is: it comprises cable core crimping position, conductive contact installed surface, connects the supporting changeover portion, described conductive contact installed surface is divided into conductive contact installed surface I and conductive contact installed surface II, interval between conductive contact installed surface I and the conductive contact installed surface II is complementary with the components and parts lug plate that band is connected, the components and parts lug plate inserts between conductive contact installed surface I and the conductive contact installed surface II, by connecting bolt conductive contact installed surface I, components and parts lug plate and conductive contact installed surface II is connected and fixed.
Described supporting changeover portion is that the rectangular area progressively dwindles rounding off to border circular areas from the conductive contact installed surface to cable core crimping position.
Described connecting bolt is two or more.
Described conductive contact installed surface I and conductive contact installed surface II are for being arranged symmetrically with up and down.
Described conductive contact installed surface I and conductive contact installed surface II are for being symmetrically arranged.
The advantage of this insertion formula cable joint: owing to adopt two conductive contact installed surfaces to contact with the components and parts lug plate, its conductive contact surfaces has increased by one times, has increased the energising area of contact site, has reduced contact resistance, improves the heating of junction.Even and in the situation of vibration, also can ensure all the time one and electrically contact installed surface and link to each other with the components and parts lug plate, thereby avoided the generation of electric arc.After particularly adopting two or more connecting bolts, strengthened the reliability that connects.In addition, the supporting changeover portion is that the rectangular area progressively dwindles rounding off to border circular areas, and is better than bending strength height, the connection supporting role of crossing the zone of traditional cable joint.

Fig. 2 is this new structural representation with insertion formula cable joint embodiment;
Fig. 3 is this new scheme of installation with insertion formula cable joint embodiment.
Embodiment
Below in conjunction with accompanying drawing to this novel being described further.
With reference to accompanying drawing 3, it comprises cable core crimping position 1, the conductive contact installed surface, connect supporting changeover portion 7, the supporting changeover portion 1 progressively dwindles rounding off for the rectangular area to border circular areas from the conductive contact installed surface to cable core crimping position, the conductive contact installed surface is divided into conductive contact installed surface 5 and lower conductive contact installed surface 4, interval between upper conductive contact installed surface 5 and the lower conductive contact installed surface 4 and components and parts lug plate 6 to be connected are complementary, components and parts lug plate 6 inserts between upper conductive contact installed surface 5 and the lower conductive contact installed surface 4, by two connecting bolts 8 with upper conductive contact installed surface 5, components and parts lug plate 6 and lower conductive contact installed surface 4 are connected and fixed.
The advantage of this insertion formula cable joint: owing to adopt two conductive contact installed surfaces to contact with components and parts lug plate 6, its conductive contact surfaces has increased by one times, has increased the energising area of contact site.Reduce contact resistance, improved the heating of junction.Even and in the situation of vibration, also can ensure all the time one and electrically contact installed surface and link to each other with components and parts lug plate 6, thereby avoided the generation of electric arc.After particularly adopting two connecting bolts, strengthened the reliability that connects.In addition, supporting changeover portion 7 progressively dwindles rounding off for the rectangular area to border circular areas, and is higher than the bending strength of the transition 2 of traditional cable joint, the connection supporting role is better.
