Abstract

The invention discloses an anti-exfoliation wiring terminal, which includes a plug connected with a wiring port of a connected device, a shrapnel on one end of the plug, and a wiring end which is arranged on one end of the plug, located on the underside of the shrapnel and connected with a wire. The wiring end presents a zigzag shape. An upper horizontal end of the zigzag wiring end is connected with the wire and a lower horizontal end of the wiring end is connected with the plug. The wiring end presents a zigzag shape so that the clearance between the shrapnel and the wiring end is relatively small, and active extent of the shrapnel is decreased. Therefore, the joint between the wiring terminal and the wiring end is firm without easy exfoliation, and the reliability of a microwave oven is thus improved.

Description

Fall prevention wiring terminal

Technical field

The present invention relates to a kind of binding post.Particularly relate to a kind of easy-to-connect, firm, the fall prevention wiring terminal of difficult drop-off.

Background technology

Usually, microwave oven is that (per second is about 2,450MHz) is heating source, by upsetting the molecules align of food, utilizes the electrical installation of the frictional heat heat food between the molecule with high frequency.

Such microwave oven is made of fuselage 10 that has possessed front panel 11, shell 12, rear board 13 and the electric control chamber that constitutes the cavity 20 of heating chamber and be provided with various electronic components as depicted in figs. 1 and 2.

Preceding end housing that constitutes fuselage 10 front structures and the fire door 14 that can open or close cavity 20 inside are installed on the front panel 11.

Shell 12 is protected cavity 20 and electric control chamber with front panel 11 and rear board 13 in two sides that constitute fuselage 10 and end face.

Be provided with the magnetron 31 of launched microwave in the inside of electric control chamber; High-tension high-tension transformer 32 is provided for magnetron 31; Be used to cool off the Air Blast fan 33 of fuselage 10 inner various electric components and the various parts such as fan electromotor 34 that drive Air Blast fan 33.

Fan electromotor 34 is fixedly mounted on the rear board 13, is provided with screen board 35 around Air Blast fan 33, guides flowing of air.

The lateral surface of cavity 20 is provided with the waveguide 36 of guiding microwave, and the front portion structure of magnetron 31 is arranged on the inside of waveguide 36.

For radiated microwaves, the side that it installs the cavity 20 of waveguide 36 communicates with the inner space of waveguide 36, and the medial surface of cavity 20 is provided with the guard shield that seals the part that communicates.The main effect of guard shield is to prevent that food slag or wet goods foreign matter from entering the inside of magnetron 31.

Usually in the microwave oven each parts to be connected with the lead of power supply be continuous by binding post.Existing binding post as shown in Figure 3, include the plug 1, the shell fragment 2 that is arranged on plug 1 one ends that link to each other with the Wiring port of connecing microwave oven, be arranged on plug 1 one ends and be positioned at the terminal stud that links to each other with lead 3 of shell fragment 2 downsides, wherein terminal stud 3 is a planar structure.

Because terminal stud 3 is a planar structure, gap between its shell fragment 2 and the terminal stud 3 is bigger, cause the amplitude of shell fragment 2 upper and lower activities bigger, therefore, when microwave oven assembled experimentize after or make microwave oven produce vibration because of other reason after, be easy to cause coming off of terminal, directly have influence on the quality of microwave oven.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of easy-to-connect, firm, the fall prevention wiring terminal of difficult drop-off.

The technical solution adopted in the present invention is: a kind of fall prevention wiring terminal, include the plug, the shell fragment that is arranged on plug one end that link to each other with the Wiring port put of be hinged with, be arranged on plug one end and be positioned at the terminal stud that links to each other with lead of shell fragment downside, the bending shape structure that horizontal, vertical, the horizontal head and the tail successively of being shaped as of described terminal stud connect.

The described terminal stud that is shaped as the connection of horizontal, vertical, horizontal head and the tail successively, the horizontal end on its top links to each other with lead, and the horizontal end of bottom links to each other with plug.

Fall prevention wiring terminal of the present invention, owing to terminal stud has been made the bending shape structure that is shaped as the connection of horizontal, vertical, horizontal head and the tail successively, make the gap between shell fragment and the terminal stud less, also just make the movable amplitude of shell fragment reduce, thereby guaranteed that binding post and Wiring port are connected firmly, difficult drop-off has improved the reliability that microwave oven uses.

Embodiment

Below, describe fall prevention wiring terminal of the present invention in detail with specific embodiment in conjunction with the accompanying drawings.

As shown in Figure 4, fall prevention wiring terminal of the present invention, include the plug 1, the shell fragment 2 that is arranged on plug 1 one ends that link to each other with the Wiring port put of be hinged with, be arranged on plug 1 one ends and be positioned at the terminal stud that links to each other with lead 4 of shell fragment 2 downsides, the bending shape structure that horizontal, vertical, the horizontal head and the tail successively of being shaped as of described terminal stud 4 connect.

Wherein, the described terminal stud 4 that is shaped as the connection of horizontal, vertical, horizontal head and the tail successively, the horizontal end on its top links to each other with lead, and the horizontal end of bottom links to each other with plug 1.

When using binding post of the present invention, push shrapnel, loose one's grip after making the plug of binding post be inserted in the Wiring port with hand, because terminal stud is a bending shape structure, gap between shell fragment and the terminal stud is less, has reduced the movable amplitude of shell fragment, so shell fragment is difficult for coming off from interface.

Claims (2)

1. fall prevention wiring terminal, include be hinged with plug (1), the shell fragment (2) that is arranged on plug (1) one end that the Wiring port put links to each other, be arranged on plug (1) one end and be positioned at the terminal stud that links to each other with lead (4) of shell fragment (2) downside, it is characterized in that the bending shape structure that horizontal, vertical, the horizontal head and the tail successively of being shaped as of described terminal stud (4) connect.

2. fall prevention wiring terminal according to claim 1 is characterized in that, the described terminal stud (4) that is shaped as the connection of horizontal, vertical, horizontal head and the tail successively, and the horizontal end on its top links to each other with lead, and the horizontal end of bottom links to each other with plug (1).
