Description
Technical field
The utility model relates to a kind of electric calorifie installation accessory, specifically a kind of heating wire connecting terminal.
Background technique
Quartz heating-pipe is the electric heating accessory in micro-wave oven, is powered under mains voltage, and electric property includes exhausted
Requirement as defined in the peace security performances such as edge resistance, pressure-resistant parameter, structure and mounting means directly affect the peace of micro-wave oven complete machine
Full performance.The fixed form of current its connecting terminal of micro-wave oven quartz heating-pipe is all to utilize the clamp ear and main body on terminal
Between plastic deformation, clamp heating wire and power supply line using clamping force, but heating wire is during the work time, is easy to cause clamp
There is the phenomenon that rising-heat contracting-cold in ear, eventually leads to heating wire or power supply line and connecting terminal is detached from, it is therefore necessary to make to it
It is further to improve.
Utility model content
The purpose of this utility model is to overcome prior art there are the shortcomings that, it is simple to provide a kind of structure, user
Just, between connecting terminal and power supply line or heating wire firm and reliable connection a kind of heating wire connecting terminal.
The utility model aim is realized with the following methods：A kind of heating wire connecting terminal, it is characterised in that：It includes
Bending is in the lug plate of " Z " font, and lug plate one end is power supply line connecting pin, and one end is heating wire connecting pin, power supply line connection
Several clamp ears are provided on end and heating wire connecting pin, after power supply line or heating wire are placed in connection sheet, bend clamp ear
Power supply line or heating wire are connect with connection sheet and are integral；The connection sheet corresponding power line connecting pin and heating wire connection
End is provided with positioning convex platform, and positioning convex platform is raised to clamp ear overbending direction.
The clamp ear is provided at least three in the same end, is distributed in connection sheet arranged on left and right sides in triangular shape.
The trapezoidal shape in clamp ear section, clamp ear and connection sheet are formed by sheet metal integrated punching.
The positioning convex platform corresponds to second setting in clamp ear.
The utility model has the beneficial effects that：1, structure is simple, and production cost is low, improves the market competitiveness.2, reasonable cloth
Office's multiple clamp ears position reduces contact resistance, promoted electric energy power so that the contact area between clamp ear and terminal increases.
3, it is provided with positioning convex platform in connection sheet, so that the joint face of power supply line or heating wire and connecting terminal has upper and lower fluctuating,
The tensile strength between power supply line or heating wire and terminal is increased, ensure that the work that this structure can be steady in a long-term.

Specific embodiment
Specific further instruction is made to the utility model with reference to the accompanying drawing.A kind of heating wire connecting terminal, feature
It is：It includes the lug plate that bending is in " Z " font, and lug plate one end is power supply line connecting pin 1, and one end is heating wire connecting pin
2, several clamp ears 3 are provided on power supply line connecting pin 1 and heating wire connecting pin 2, and power supply line 4 or heating wire 5 are placed on connection
After on piece, power supply line 4 or heating wire 5 are connect with connection sheet and are integral by bending clamp ear 3；The connection sheet corresponding power
Line connecting pin 1 and heating wire connecting pin 2 are provided with positioning convex platform 6, and positioning convex platform 6 is raised to 3 overbending direction of clamp ear.
The clamp ear 3 is provided at least three in the same end, is distributed in connection sheet arranged on left and right sides in triangular shape.
The trapezoidal shape in 3 section of clamp ear, clamp ear 3 and connection sheet are formed by sheet metal integrated punching.
The positioning convex platform corresponds to second setting in clamp ear.
Working principle：In wiring, the terminals of power supply line or heating wire are placed into the cladding model of clamp ear by user
In enclosing, then clamp ear is bent to main direction using special fixture, so that clamp ear is covered in the main body of lug plate.
Wherein, in order to increase the contact area between clamp ear and power supply line or heating wire, clamp ear 3 is provided in the same end in this case
At least three, connection sheet arranged on left and right sides is distributed in triangular shape.Therefore, three clamp ears and power supply line or heating wire are utilized
Contact is increasing contact area, while reducing resistance, is also increasing the tensile strength between power supply line and heating wire.Wherein need
To illustrate that：According to the needs of use, as shown in Figs 1-4, the extending direction of clamp ear can be the upper end of connecting pin, can also be such as
Shown in Fig. 5-8, the extending direction of clamp ear can be the lower end of connecting pin, actual conditions, and user can voluntarily select.
Further：In order to avoid connecting terminal is influenced by expanding with heat and contract with cold in use, clamp ear is caused to go out
Now loosening causes power supply line or heating wire to fall off, in connection sheet corresponding power line connecting pin 1 and heating wire connecting pin 2 in this case
It is provided with positioning convex platform 6, positioning convex platform 6 is raised to 3 overbending direction of clamp ear.The setting of positioning convex platform may make power supply line or
After heating wire is connect with clamp ear, so that the connecting pin of power supply line or clamp ear generates the difference in height of " convex " font, utilization is convex
Platform increases bonding strength, so that avoiding expanding with heat and contract with cold because of clamp ear leads to heating wire or power line from dropping, therefore can be widely popularized
It uses.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.
