Description

Technical Field

[0001] The present invention relates to a knife-type waterproof connector, in particular to a knife-type waterproof connector which has both signal and power conduction functions, can withstand large currents and has a foolproof function. Background Art

[0002] When various electronic devices need to connect to various circuits such as power or signals, it is common to fix male and female connectors on both ends of the wires, and then form an electrical connection through the quick plug-in of the male and female connectors. When used in commercially available electric bicycles, they need to be able to transmit signals and high currents simultaneously and require the function of quick disassembly and assembly. Therefore, the use of a knife-type connector is a better choice.

[0003] However, while conventional blade-type connector structures offer high structural strength and a large conductive area, they are unable to meet the demands of higher currents. While high currents can be achieved by connecting several pins in parallel, this prevents the connectors from being easily docked. Otherwise, current differences between the connections could damage the connectors, resulting in a single insertion direction.

[0004] However, paying attention to the plugging direction is laborious and time-consuming for the user, so a foolproof mechanism is often used in connectors to make them easier to plug in.

[0005] Therefore, the inventor has designed the present invention based on the above experience, conducted extensive research and trial samples, and made numerous revisions and improvements. Summary of the Invention

The distance is also divided into the anti-mistake spacing and normal spacing to match the male end knife. The surface of the female end seat is concave with several first knife grooves and several second knife grooves around the female end knife slot to match the first knife seat and the second knife seat; through the above structure, the male end seat is inserted into the female end seat, so that the male end knife contacts the conductive seat, the first knife seat is matched with the first knife groove, and the second knife seat is matched with the second knife groove. The waterproof gasket is sandwiched between the first knife seat and the second knife seat and the first knife groove and the second knife groove to prevent water from penetrating between the male end seat and the female end seat, thereby having a waterproof effect, so as to complete the knife-type waterproof connector.

[0009] Furthermore, the male end switch provided with the first switch holder is in parallel state for transmitting high current.

[0010] Preferably, the height of several male end blades provided with the first blade seat is greater than the height of the male end blade provided with the second blade seat and has an anti-mistake height, so that after the male end seat is inserted into the female end seat, when the male end blade provided with the first blade seat contacts the conductive seat first, it is ensured that the male end blade provided with the second blade seat has not yet contacted the conductive seat.

[0011] Preferably, the height of the first gate knife seat is higher than the height of the second gate knife seat; the depth of the first gate knife groove is matched with the first gate knife seat, and the depth of the second gate knife groove is matched with the second gate knife seat, so the depth of the first gate knife groove is greater than the depth of the second gate knife groove.

[0012] Preferably, the waterproof gasket includes a male-end waterproof gasket and a female-end waterproof gasket, the male-end waterproof gasket is attached to the male-end seat, and the female-end waterproof gasket is attached to the female-end seat.

[0013] Preferably, the first knife seats are all located on the left side of the male end seat, and the second knife seats are all located on the right side of the male end seat; the first knife slots are all located on the left side of the female end seat, and the second knife slots are all located on the right side of the female end seat; the number of the anti-mistake spacing is one; the anti-mistake spacing is located between the two second knife seats on the far right and between the two second knife slots on the far right.

[0014] Compared with the efficacy of previous technologies:

[0015] By means of this invention, the present invention uses an anti-mistake distance to prevent the user from inserting the male end seat in the wrong direction, so that the user can quickly understand the wrong direction and rotate the male end seat to insert it in the correct direction. It also has the effect of easy plugging. If the user insists on using the wrong direction, it still cannot be inserted into the female end seat, which has a safety effect.

[0040] To help you better understand the purpose, features, and effects of the present invention, please refer to the following [Brief Description of the Figures] for details:

[0041] Generally, according to the present invention, first Figures 1 to 4As shown in the figure, the present invention provides a knife-type waterproof connector, which includes a male end seat 10, a female end seat 20, and a waterproof gasket 30, wherein the male end seat 10 is provided with a plurality of male end knife gates 11 side by side, and the distances between the plurality of male end knife gates 11 are different and are divided into at least one anti-fool spacing A and a plurality of normal spacings B, and the lengths of the anti-fool spacing A and the normal spacing B are different. The surface of the male end seat 10 is provided with a plurality of first knife gate seats 12 and a plurality of second knife gate seats 13 around the male end knife gate 11; the female end seat 20 is provided with a plurality of female knife gate slots 21 for the male end knife gate 11 to be provided. The male blade 11 is inserted into the female blade slot 21. The cross-sectional area of the female blade slot 21 is larger than that of the male blade 11, which allows for quick insertion. A conductive seat 211 is provided in the female blade slot 21 to contact the male blade 11 for electrical conduction. The distance between the female blade slots 21 is also divided into the anti-mistake spacing A and the normal spacing B to match the male blade 11. The surface of the female base 20 is concavely provided with a plurality of first blade slots 22 and a plurality of second blade slots 23 surrounding the female blade slot 21 to match the first blade seat 12 and the second blade seat 13.

[0042] Depend on Figure 5 and Figure 8 As shown, through the above structure, the male end seat 10 is inserted into the female end seat 20, so that the male end knife 11 contacts the conductive seat 211, the first knife seat 12 cooperates with the first knife groove 22, and the second knife seat 13 cooperates with the second knife groove 23. The waterproof gasket 30 is sandwiched between the first knife seat 12 and the second knife seat 13 and the first knife groove 22 and the second knife groove 23 to prevent water from penetrating between the male end seat 10 and the female end seat 20, thereby having a waterproof effect, completing the knife-type waterproof connector.

[0043] Depend on Figure 8 As shown in the figure, when the male end seat 10 is inserted into the female end seat 20, the two can be normally combined. Figures 9 to 11 As shown in the figure, when the male end seat 10 is rotated 180 degrees and inserted into the female end seat 20, the anti-fool mechanism will be triggered. Due to the existence of the anti-fool spacing A, the male end seat 10 is plugged into the female end seat 20. When the spacing is different, it will be difficult to insert the male end blade 11 into the female end blade slot 21, thereby achieving a preliminary anti-fool effect. Figure 12 and Figure 13 As shown, when the user intends to forcibly insert part of the male blade 11 into the female blade slot 21 in an inclined manner, the other part of the male blade 11 will be unable to be inserted into the female blade slot 21 due to the effect of the inclination, thereby achieving a further fool-proof effect.

[0044] The present invention provides a knife-type waterproof connector, wherein the male knife 11 provided with the first knife seat 12 is in a parallel state for transmitting high current.

[0045] Depend on Figure 3 As shown in the figure, the present invention provides a knife-type waterproof connector, wherein the height of the male end knife 11 provided with the first knife seat 12 is greater than the height of the male end knife 11 provided with the second knife seat 13 and has a foolproof height (C), and then by Figures 5 to 7 As shown, after the male end seat 10 is inserted into the female end seat 20, the male end knife 11 provided with the first knife seat 12 first contacts the conductive seat 211, ensuring that the male end knife 11 provided with the second knife seat 13 has not yet contacted the conductive seat 211. If the male end knife 11 is in parallel, this measure can prevent all the male end knifes 11 from transmitting an unloadable current when inserted in the wrong direction, thereby causing damage to the connector and the equipment.

[0046] The present invention provides a knife-type waterproof connector, wherein the height of the first knife seat 12 is higher than the height of the second knife seat 13; the depth of the first knife groove 22 is matched with the first knife seat 12, and the depth of the second knife groove 23 is matched with the second knife seat 13, so the depth of the first knife groove 22 is also greater than the depth of the second knife groove 23. Before the male end seat 10 is inserted into the female end seat 20, the insertion direction can be confirmed by the different heights of the first knife seat 12 and the second knife seat 13 or the different depths of the first knife groove 22 and the second knife groove 23, which has a fool-proof effect. Due to the different depths and heights, the first knife seat 12 cannot be installed in the second knife groove 23, and the second knife seat 13 cannot be installed in the first knife groove 22.

[0047] Depend on Figures 1 to 4 As shown, the present invention provides a knife-type waterproof connector, wherein the waterproof gasket includes a male waterproof gasket 14 and a female waterproof gasket 24. The male end seat 10 is affixed with a male waterproof gasket 14, and the female end seat 20 is affixed with a female waterproof gasket 24. When the male end seat 10 and the female end seat 20 are further combined, the male end waterproof gasket 14 and the female end waterproof gasket 24 can achieve a waterproof effect.

[0048] Depend on Figure 3As shown, the present invention provides a knife-type waterproof connector, wherein the first knife seats 12 are all located on the left side of the male end seat 10, and the second knife seats 13 are all located on the right side of the male end seat 10; the first knife slots 22 are all located on the left side of the female end seat 20, and the second knife slots 23 are all located on the right side of the female end seat 20; the number of the anti-foolproofing distance A is one; the anti-foolproofing distance A is located between the two second knife seats 13 on the far right and between the two second knife slots 23 on the far right, and has the effect of preferentially preventing the male end knife 11 provided with the first knife seat 12 from being inserted into the female end knife slot 21 when the anti-foolproofing mechanism is triggered by rotating the male end seat 10.

[0049] The above-mentioned knife-type waterproof connector has the following advantages: (1) the cross-sectional area of the female knife slot 21 is larger than the cross-sectional area of the male knife 11, and has the effect of quick insertion; (2) due to the existence of the anti-foolproofing spacing A, when the male end seat 10 is plugged into the female end seat 20, the different spacing distances will make it difficult to insert the male knife 11 into the female knife slot 21, thereby achieving a preliminary anti-foolproofing effect. When the user intends to forcibly insert part of the male knife 11 into the female knife slot 21 in an inclined manner, the other part of the male knife 11 will be unable to be inserted into the female knife slot 21 due to the influence of the tilt, thereby achieving a further anti-foolproofing effect. When the user starts to plug in, if it is not smooth, it will immediately turn to the correct direction, thereby reducing the user's inspection time and making the plugging process easier and safer.

[0050] However, the above is only a preferred embodiment of the present invention and cannot limit the scope of protection of the present invention. All equivalent changes and modifications made according to the contents recorded in the claims of the present invention should still fall within the scope of the patent of the present invention.
