Description

Technical Field

[0001] This utility model relates to an I / O terminal block, and more particularly to an improved I / O terminal block snap-fit ​​structure. Background Technology

[0002] The existing I / O terminal block's latching structure consists of a hook on the socket and a plastic handle with a cantilever structure on the plug. The plug and socket are locked by engaging the latch on the plastic handle with the hook on the socket. The plug of the terminal block is pulled out by pressing the head of the plastic handle with a finger to release the latch.

[0003] When the socket housing size is limited and there is not enough space to accommodate a finger, the plug of the terminal block is difficult to pull out, which will cause inconvenience to the user. Summary of the Invention

[0004] To overcome the above-mentioned defects, this utility model provides an improved IO terminal block snap-fit ​​structure, which enables the terminal block to be used normally in scenarios where the space of the socket housing is small.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an improved IO terminal block snap-fit ​​structure, including a hook on the socket housing of the IO terminal block and an elastic handle on the plug of the IO terminal block. The elastic handle is provided with a locking point, which can be engaged with the hook. The elastic handle can overcome its own elasticity to disengage the locking point from the hook. A lifting handle is hinged on the elastic handle, and pulling the lifting handle can drive the elastic handle to move.

[0006] As a further improvement of this utility model, the elastic handle is an elastic cantilever structure integrally formed on the side wall of the IO terminal block plug, and the lifting handle is hinged to the free end of the cantilever structure of the elastic handle.

[0007] As a further improvement of this utility model, the free end of the elastic handle is provided with protruding column shafts on both sides of the side wall along the thickness direction of the IO terminal block, and one end of the lifting handle forms a U-shaped opening structure. The two sides of the U-shaped opening structure at one end of the lifting handle are provided with shaft holes. The U-shaped opening structure at one end of the lifting handle can be tightly fitted onto the outside of the free end of the elastic handle, and the protruding column shaft on the elastic handle can be rotatably inserted into the shaft hole at one end of the lifting handle.

[0008] As a further improvement of this utility model, an eccentric stop is provided on the outer circumferential wall of the convex pivot shaft on the free end of the elastic handle, extending radially. A fan-shaped limiting groove is also provided on the inner wall of the U-shaped opening structure at one end of the lifting handle. The eccentric stop can be slidably inserted into the fan-shaped limiting groove. The eccentric stop stops on the two side walls of the fan-shaped limiting groove along its sliding direction, thereby making the lifting handle only able to rotate around the convex pivot shaft within a set angle range.

[0009] As a further improvement of this utility model, the end edge of the convex column shaft is formed with a chamfered surface or a rounded surface.

[0010] As a further improvement of this utility model, the thickness of one end of the lifting handle with a U-shaped opening structure along its rotation direction is greater than the thickness of the other end of the lifting handle, and the ends of the two side walls of the U-shaped opening structure at one end of the lifting handle respectively form a circular ring structure, and the inner hole of the circular ring structure is a shaft hole.

[0011] As a further improvement of this utility model, a limiting flange with radially outward expansion is formed on the other end of the lifting handle opposite to the elastic handle.

[0012] As a further improvement of this utility model, the locking point on the elastic handle is an inverted protrusion, and the hook on the socket housing is also an inverted protrusion located on the side wall of the socket housing, and the inverted protrusions of the locking point and the hook are opposite in direction.

[0013] As a further improvement of this utility model, two protruding ribs are provided at intervals on the side wall of the socket housing, and the elastic handle is accommodated between the two protruding ribs and swings elastically between the two protruding ribs.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a lifting handle hinged to the end of the elastic handle on the side wall of the plug. The lifting handle can rotate around the top pivot of the elastic handle. By pulling the lifting handle, the buckle structure can be unlocked and the terminal block plug can be pulled out. Even in situations where the space of the socket housing is small, the terminal block can be used normally. Since the lifting handle can rotate, the user can adjust the direction of the lifting handle during use to adjust a more suitable angle to unlock or pull out the terminal block plug.

[0026] Example: An improved I / O terminal block snap-fit ​​structure includes a hook 11 on the socket housing 1 of the I / O terminal block and an elastic handle 21 on the plug 2 of the I / O terminal block. The elastic handle 21 is provided with a locking point 211, which can be engaged with the hook 11. The elastic handle 21 can disengage the locking point 211 from the hook 11 by overcoming its own elasticity. A lifting handle 22 is hinged to the elastic handle 21, and pulling the lifting handle 22 can drive the elastic handle 21 to move.

[0027] When unlocking, simply rotate the lifting handle 22 to the appropriate angle and then pull the lifting handle 22 to move the elastic handle 21, thereby causing the locking point 211 on it to disengage from the hook 11 on the socket housing 1. This structure eliminates the need to manually operate the elastic handle 21 when unlocking. Even in scenarios where the space of the socket housing 1 is small, the plug 2 of the terminal block can be easily unlocked and pulled out, allowing the terminal block to be used normally in a small space.

[0028] Furthermore, since the bottom of the lifting handle 22 can rotate, the user can adjust the tilt direction of the lifting handle 22 during use to adjust to a more suitable angle to unlock or unplug the plug 2 of the terminal block, making it easier for the user to unlock or unplug the plug 2 of the terminal block.

[0029] The elastic handle 21 is an integrally formed elastic cantilever structure on the side wall of the IO terminal block plug 2, and the lifting handle 22 is hinged to the free end of the cantilever structure of the elastic handle 21. The elastic cantilever structure provides the locking point 211 with an elastic retaining force to keep it engaged with the hook 11. In addition, the elastic handle 21 can also be other elastic structures.

[0030] The elastic handle 21 has protruding pivot shafts 212 on both sides of its free end along the thickness direction of the IO terminal block. One end of the lifting handle 22 forms a U-shaped opening structure 221. The two sides of the U-shaped opening structure 221 at one end of the lifting handle 22 have shaft holes 222. The U-shaped opening structure 221 at one end of the lifting handle 22 can be tightly fitted onto the outside of the free end of the elastic handle 21, and the protruding pivot shafts 212 on the elastic handle 21 can be rotatably inserted into the shaft holes 222 at one end of the lifting handle 22. This structure facilitates the hinged assembly of the lifting handle 22 and the elastic handle 21. After assembly, the protruding pivot shafts 212 on the free end of the elastic handle 21 can be relatively rotatably inserted into the shaft holes 222 on both sides of the U-shaped opening structure 221 of the lifting handle 22.

[0031] An eccentric stop 213 is radially extended on the outer circumferential wall of the convex pivot shaft 212 at the free end of the elastic handle 21. A fan-shaped limiting groove 223 is also provided on the inner wall of the U-shaped opening structure 221 at one end of the lifting handle 22. The eccentric stop 213 is slidably inserted into the fan-shaped limiting groove 223. The eccentric stop 213 stops against the two side walls of the fan-shaped limiting groove 223 along its sliding direction, thus ensuring that the lifting handle 22 can only rotate around the convex pivot shaft 212 within a set angle range. The eccentric stop 213 on the convex pivot shaft 212 of the elastic handle 21, which can only slide within the fan-shaped limiting groove 223, prevents the lifting handle 22 from rotating excessively during use, ensuring that the lifting handle 22 remains at an angle convenient for user use within its movable range.

[0032] The end edge of the convex pivot 212 is chamfered or rounded to facilitate the assembly of the lifting handle 22 and the elastic handle 21.

[0033] The thickness of one end of the lifting handle 22 with the U-shaped opening structure 221 along its rotation direction is greater than the thickness of the other end of the lifting handle 22. Furthermore, the ends of the two side walls of the U-shaped opening structure 221 at one end of the lifting handle 22 respectively form annular structures, and the inner hole of the annular structure is a shaft hole 222. This structure can enhance the strength of the U-shaped opening structure 221 of the lifting handle 22 and prevent damage under tensile force.

[0034] A limiting flange 224 with a radially outwardly expanding dimension is formed on the other end of the lifting handle opposite to the elastic handle 21. During operation, the limiting flange 224 can be gripped for operation, making operation convenient.

[0035] The locking point 211 on the elastic handle 21 is an inverted protrusion, and the hook 11 on the socket housing 1 is also an inverted protrusion located on the side wall of the socket housing 1, with the locking point 211 and the hook 11 having opposite directions. This double-inverted structure with opposite directions is used for the fastening connection, resulting in a simple structure and allowing the plug 2 to smoothly avoid interference when plugged into the socket, preventing interference between the locking point 211 and the hook 11.

[0036] The socket housing 1 is also provided with two protruding ribs 23 at intervals on its side wall. The elastic handle 21 is accommodated between the two protruding ribs 23 and swings elastically between the two protruding ribs 23. The two protruding ribs 23 can guide the swing direction of the elastic handle 21.
