Description
Technical field
The utility model relates to the electric equipment connector in power technology field, especially a kind of concave-convex type electric equipment connector.
Background technology
At present, the connection between electric equipment adopts flat copper line or aluminium row to connect more, owing to connecting the restriction of row's length, adopts overlapping mode to connect more, adopts conductive paste to increase contact between two-layer.Because contact area is less, make contact resistance larger, in the situation that large electric current passes through, contact resistance has caused the rising of connector temperature, thereby causes busbar fault.
Summary of the invention
The purpose of this utility model is to make up the deficiencies in the prior art part, provides a kind of and can increase joint contact surfaces, reduces contact resistance, reduces the concave-convex type electric equipment connector of rate of breakdown.
The purpose of this utility model realizes by following technological means:
A kind of concave-convex type electric equipment connector, it is characterized in that: comprise overlap joint piece and lower overlap joint piece, upper overlap joint piece is placed on lower overlap joint piece, on this, the contact-making surface of overlap joint piece and lower overlap joint piece is made identical tongue and groove structure mutually, on upper overlap joint piece and lower overlap joint piece, all make multiple vertical bolts hole, upper overlap joint piece and lower overlap joint piece are fixedly mounted with connection by the bolt being installed in bolt hole.
And described upper overlap joint piece and the contact-making surface of lower overlap joint piece apply one deck conductive paste layer.
And described upper overlap joint piece and the contact-making surface of lower overlap joint piece refer to the bottom surface of overlap joint piece and the upper surface of lower overlap joint piece.
Advantage of the present utility model and good effect are:
1, two electric equipment lap joints are made as tongue and groove pattern by this connector, overlaps by multiple tongue and grooves, places conductive paste in inside grooves, then adopts bolt to be fixed connection.This structural design can increase contact area, reduces contact resistance, reduce the temperature rise of joint area, finally avoids the generation of busbar fault, ensures power supply safety.
2, the piece of overlap joint up and down in this connector is with bolts can increase the degree that is connected firmly.
3, the utility model be a kind of reasonable in design, simple in structure, easy to manufacture, be easy to realize concave-convex type electric equipment connector, use this structure can make the contact area of electric equipment connector increase by 1.2～1.4 times, reduce the contact resistance at two sections of busbar shiplap joint places, thereby increase the through-current capability of lap-joint, reduce the temperature rise of joint, reduce fault occurrence probability.
Brief description of the drawings

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the schematic diagram of upper overlap joint piece;
Fig. 4 is the schematic diagram of lower overlap joint piece.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection range of the present utility model with this.
A kind of concave-convex type electric equipment connector, comprise overlap joint piece 1 and lower overlap joint piece 3, upper overlap joint piece is placed on lower overlap joint piece, on this, the contact-making surface of overlap joint piece and lower overlap joint piece is made identical tongue and groove structure mutually, it is the groove 7 in tongue 5 and the Fig. 4 in Fig. 3, this groove and tongue are multiple, and the contact-making surface of upper overlap joint piece and lower overlap joint piece applies one deck conductive paste layer.The contact-making surface of upper overlap joint piece and lower overlap joint piece refers to the bottom surface of overlap joint piece and the upper surface of lower overlap joint piece.On upper overlap joint piece and lower overlap joint piece, all make multiple vertical bolts hole 6, upper overlap joint piece and lower overlap joint piece are fixedly mounted with connection by nut 4 and the bolt 2 that is installed in bolt hole.Number of bolt hole is not limit, and is four in the present embodiment.
Execution mode of the present utility model is as follows:
The first step: the overlap joint side of upper overlap joint piece and lower overlap joint piece is cleaned out respectively;
Second step: be coated with appropriate conductive paste in overlap joint side;
The 3rd step: by the male and fomale(M&F) fastening of upper overlap joint piece and lower overlap joint piece;
The 4th step: use screw bolt and nut to carry out fastening.
Claims (3)
