1. A locking device attached to a junction box, comprising: a male part; comprising: a plug-in unit extended at an angle from said male part; a pair of protruded units having a locking tab formed on edges of said plug-in unit; an outward projection disposed above said locking tab; and a slant portion formed on top of said outward projection; and a female part; comprising: a hollow main body having an inside wall; a pair of extrusions disposed at said inside wall of said hollow main body corresponding to said pair of locking tabs of said male part; and a step formed in the lower part of said extrusion of said female part geometrically shaped to match said locking tab of said male part, wherein inserting said male part into said female part, said locking tab of said pair of protruded units of said male part and said step of female part are clamped together at the opposite sides, wherein simultaneously said outward projection of said male part contacts with the proximal end of said extrusion and thereby securely clamping said male part and said female part in a locked position, wherein in a locked position said female part is located between each one of said pair of protruded unit of said male part.
3. The locking device according to claim 2, wherein there are two locking tabs of said male part.
4. The locking device according to claim 2, wherein said plug-in unit is a plate.
5. The locking device according to claim 3, wherein said plug-in unit is a plate.
6. The locking device according to claim 4, wherein said male part and said female part are injection molded single piece units.
7. The locking device according to claim 5, wherein said male part and said female part are injection molded single piece units.
8. The locking device according to claim 6, wherein said device can be formed in a photovoltaic junction box, wherein said male part is the top cover of said junction box, and said female part is said box.
9. The locking device according to claim 7, wherein said device can be formed in a photovoltaic junction box, wherein said male part is the top cover of said junction box, and said female part is said box.
10. A locking device, comprising: a male part; comprising: a plug-in unit extended at an angle from said male part; a pair of protruded units having a locking tab formed on edges of said plug-in unit; an outward projection disposed above said locking tab; and a slant portion formed on top of said outward projection; and a female part; comprising: a hollow main body having an inside wall; a pair of extrusions disposed at said inside wall of said hollow main body corresponding to said pair of locking tabs of said male part; and a step formed in the lower part of said extrusion of said female part geometrically shaped to match said locking tab of said male part, wherein inserting said male part into said female part, said locking tab of said pair of protruded units of said male part and said step of female part are clamped together at the opposite sides, wherein simultaneously said outward projection of said male part contacts with the proximal end of said extrusion and thereby securely clamping said male part and said female part in a locked position, wherein in a locked position said female part is located between each one of said pair of protruded unit of said male part.
11. The locking device according to claim 10, wherein said plug-in unit is extended from said male part at an angle of about ninety degrees.
12. The locking device according to claim 11, wherein there are two locking tabs of said male part.
13. The locking device according to claim 12, wherein said plug-in unit is a plate.
14. The locking device according to claim 13, wherein said male part and said female part are injection molded single piece units.
15. A combination key for releasing the locking device according to claim 1, comprising: a plate having an opening; a protrusion having an inclined portion formed at said plate and extended from thereof; and a pair of tilted hook formed at said plate extended from thereof and disposed beside said protrusion, wherein said pair of tilted hook is inclined toward said plate, and said protrusion having an inclined portion tilted toward said plate, wherein inserting said combination key into said inside wall of said hollow main body of said female part to unlock said locking buckle device, wherein said inclined portion of said protrusion of said key can be pressed toward said slant portion of said outward projection of said male part to allow said outward projection of said male part release from the upper side of said extrusion of said female part, wherein simultaneously inserting said key into said female part creates a vertical pressure forcing said locking tab of said male part out of said extrusion of said female part, wherein said pair of tilted hook therefore clasping corresponding pair of said protruded units of said plug-in unit of said male part, wherein the user pulls out said key from said hollow main body of said female part, said titled hook of said key draws said male part from said hollow main body of said female part.
16. The combination key according to claim 15, wherein said key is injection molded and the said plate, said protrusion and said pair of tilted hook are formed of a single piece unit.
17. The combination key according to claim 16, wherein said key is a rectangle plate or a square plate.
18. A combination key for releasing the locking device according to claim 3, comprising: a plate having an opening; a protrusion having an inclined portion formed at said plate and extended from thereof; and a pair of tilted hook formed at said plate extended from thereof and disposed beside said protrusion, wherein said pair of tilted hook is inclined toward said plate, and said protrusion having an inclined portion tilted toward said plate, wherein inserting said combination key into said inside wall of said hollow main body of said female part to unlock said locking buckle device, wherein said inclined portion of said protrusion of said key can be pressed toward said slant portion of said outward projection of said male part to allow said outward projection of said male part release from the upper side of said extrusion of said female part, wherein simultaneously inserting said key into said female part creates a vertical pressure forcing said locking tab of said male part out of said extrusion of said female part, wherein said pair of tilted hook therefore clasping corresponding pair of said protruded units of said plug-in unit of said male part, wherein the user pulls out said key from said hollow main body of said female part, said titled hook of said key draws said male part from said hollow main body of said female part.
19. The combination key according to claim 18, wherein said key is injection molded and the said plate, said protrusion and said pair of tilted hook are formed of a single piece unit.
20. The combination key according to claim 18, wherein said key is a rectangle or a square plate.
In FIGS. 1 and FIG. 4, the female part 2 has a hollow main body 21. As shown in FIG. 4, a pair of extrusions 22 disposed at inside wall 28 of hollow main body 21 of female part 2 corresponds to the pair of locking tabs 32 of male part 1 in FIG. 1.
