Abstract
A kind of cable termination connection terminal, including connection terminal, cable connector, connection terminal are connected with cable connector；One surface of the joint face of the connection terminal is provided with jagged bayonet, is provided with through-hole on the joint face.The concavo-convex frictional force that can increase horizontal and vertical direction is set by joint face, reduces the generation loosened and do not fasten phenomenon generated by external force；The use of concavo-convex joint face expands actually active contact area so that the contact area of two wire clamp joint faces increases, and plays the role of reducing contact resistance；The shortcomings that conventional planar connection terminal that concavo-convex connection structure also avoids easily slides when installing, displacement, and installation is more convenient, improves operating efficiency.
Description
Technical field
The utility model relates to power domains, more particularly to a kind of cable termination connection terminal.
Background technique
During cable run O&M, the fever of discovery cable termination connection terminal frequently occurs, and handles fever
Defect need power failure to handle, the abnormal heating of terminal clamp is frequently experienced in high load capacity period, and will such as have a power failure processing, it will face
Face following problem: the heavier power failure difficult coordination of line load, line outage cause no small economic loss, falls load operation also prestige
The safe and stable operation of power grid is coerced, a kind of common fault of transmission line of electricity is already become.
Since current most-often used cable termination connection terminal is using the fitting contact of two planes, captive screw is fixed
's.First: wire clamp in flakes between inordinate wear and wind put caused by deform and can contact pressure be caused to become smaller, there is poor contact
Latency defect.Second: if the metalwork that any two separate links together, the face how smooth no matter contacted,
It is impossible to be complete face contact, their real contact area is centainly less than theoretical contact area, and wire clamp contact surface is deposited
Effective contact area of junction can be made to be obviously reduced in phenomena such as burr, subtle deformation, indirectly make the contact of junction
Resistance increases, and in the biggish situation of current-carrying load, equally causes apparent fever phenomenon.
Utility model content
For big there are poor contact and calorific value deficiency between solving prior art cable termination connection terminal in flakes, this
Utility model provides a kind of cable termination connection terminal.
To realize the above purpose of utility model, the technical solution adopted is that:
A kind of cable termination connection terminal, including connection terminal, cable connector, connection terminal are connected with cable connector
It connects, a surface of the joint face of the connection terminal is provided with concavo-convex bayonet, is provided with through-hole on the joint face.
The concavo-convex frictional force that can increase horizontal and vertical direction is set by joint face, reduces the loosening and not generated by external force
Fasten the generation of phenomenon；The use of concavo-convex joint face expands reality so that the contact area of two connection terminal joint faces increases
The effective contact area in border plays the role of reducing contact resistance；The conventional planar wire clamp that concave-convex connection structure also avoids
It is easily slided when installation, the shortcomings that displacement, and installs more convenient, improve operating efficiency.
Preferably, the junction surface is zigzag, and sawtooth is set gradually from left to right in joint face.
Preferably, the number of openings can be set multiple, to increase the stability of connection.
Preferably, it is coated with insulation coating on the disconnected face of the connection terminal, to reduce the air of connector
Discharge effect.
Preferably, the cable connection head surface is provided with aperture, to increase heat dissipation effect.
Preferably, the connection terminal uses aluminum alloy materials, can mitigate cable weight, reduces installation cost, subtracts
The abrasion of few equipment and cable, keeps installment work lighter.
Preferably, thermal dispersant coatings are coated on the disconnected face of the cable connecting terminals, increase the heat dissipation of connection terminal
Effect.
Specific use process is as follows:
Two cable termination connection terminals are matched, by the sawtooth joint face pair of two cable termination connection terminals
Together, rabbeted by the joint face of zigzag bayonet each other, the through-hole of two cable termination connection terminals is aligned after interlocking, is used
Screw passes through the through-hole of two cable termination connection terminals, reuses nut fastening, what forms a stable electrical connection from
Component.
Compared with prior art, the utility model has the beneficial effects that
This cable connection upper thread folder uses the connection structure of concavo-convex interlocking, increases the friction in horizontal and vertical direction
Power reduces the generation loosened and do not fasten phenomenon generated by external force.
The use of concavo-convex joint face expands actually active connect so that the contact area of two wire clamp joint faces increases
Contacting surface product plays the role of reducing contact resistance.
The shortcomings that conventional planar wire clamp that concavo-convex connection structure also avoids easily slides when installing, displacement, and install more
It is convenient, improve operating efficiency.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；
The utility model is further elaborated below in conjunction with drawings and examples.
Embodiment 1

The surface of joint face 3 of connection terminal 1 be provided with concavo-convex bayonet, be provided with through-hole 4 on the joint face 3.It will
Joint face 3 is set as the concavo-convex frictional force that can increase horizontal and vertical direction, reduces the loosening and not generated by external force
Fasten the generation of phenomenon；The use of concavo-convex joint face 3 expands so that the contact area of two connection terminal joint faces 3 increases
Actually active contact area plays the role of reducing contact resistance, while the conventional planar connection terminal installation also avoided
When easily slide, the shortcomings that displacement, and install more convenient, improve operating efficiency.
Preferably, 3 surface of joint face is zigzag, and sawtooth is set gradually from left to right in joint face 3.
Preferably, 4 quantity of through-hole can be set multiple, with the better stability for increasing connection.
Specific embodiment is as follows:
Two cable termination connection terminals are matched, the sawtooth joint face 3 of two cable termination connection terminals is right
Together, rabbeted by the joint face 3 of zigzag bayonet each other, the through-hole 4 of two cable termination connection terminals is aligned after interlocking, makes
The through-hole 4 that two cable termination connection terminals are passed through with screw reuses nut fastening, electrically connects from what formation one is stable
Relay part.
