DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiment

[0022] As shown in FIGS. 1-6, the terminal block for the oven includes base 01, terminal 02, screw 03 and grounding copper sheet 04. The shape of the base 01 is shown like the Chinese character . There are three terminal mounting slots 05 evenly on the base 01 along the traverse direction. The upper sides of the both sides of the terminal mounting slots 05 are provided an openings 06, and one end of the terminal mounting slot 05 is provided with a wire insertion hole 07. The wire insertion hole 07 communicates with an opening 06, and the middle of the both sides or both sides of the terminal mounting slots 05 are provided with retaining grooves which penetrate through the bottom of the base 01, and the upper portion of the retaining groove is provided with an elastic buckle 08. The middle of the terminal 02 is provided with a wire installation through hole 09 which penetrate s through the both ends of the terminal. The terminal 02 is mounted in the mounting terminal mounting slot 05, the wire insertion hole 07 communicates with the wire installation through hole 09, and the elastic buckle 08 is pressed on the top of the terminal 02. The grounding copper sheet 04 covers and fits the upper surface of terminal 02 and is fixed connection by two screws 03. The screws 03 are evenly distributed along the direction of the wire installation through hole 09, and the screws 03 are vertically passed through the top of terminal 02 into the wire installation through hole 09. The wire enters into the wire installation through hole 09, and the roots of the screws 03 are pressed against the wire. The creepage distance specified in the safety specification is maintained between the terminal mounting slots 05 to effectively ensure the adjacent terminals 02 will not affect each other in extreme cases during the use of the terminal block. Besides, an clearance 10 is provided between the terminal mounting slots 05, which can provide a good ventilation condition. The clearance 10 is longitudinally provided with a reinforced connecting plate 11, which makes the product more beautiful and light, and the reinforced connecting plate 11 is used to ensure the stability of the overall structure of the terminal block. The bottom of the base 01 is hollowed out to design a number of grooves 12, and the grooves 12 communicate with each other, and further the grooves 12 communicate with the retaining grooves, so as to make the product more beautiful and light. The base 01 is made of PC+10% glass fiber or other heat-resistant engineering plastics to enhance its heat resistant temperature and strength. The terminal 02 is made of aluminum or copper, and the surface of the terminal is zinc-plated. The screw 03 is made of standard carbon steel, and the surface of the screw is nickel-plated or zinc-plated, and quenched. The grounding copper sheet is made of red copper according to standard requirements, so that the overall performance of the terminal block is better, and the rated current is higher.
