Description

Pluggable connector

The present invention relates to a connector, and more particularly to a pluggable connector.

The pluggable connector is mainly used for docking an electronic device socket, so that the electronic device can externally connect the transmission line or other peripheral devices. For example, a Small Form-factor Pluggable (SFP) connector is usually provided with a cable or fiber optic port for external cable or fiber optic cable assembly.

Generally, when the pluggable connector is inserted into the socket of the electronic device, the pluggable connector is fixed in the socket by a locking mechanism, and if the pluggable connector needs to be pulled out, an unlock is utilized. The mechanism releases the locking mechanism to remove the pluggable connector from the socket. However, the current unlocking mechanism is usually a complicated mechanism composed of a plurality of components. Therefore, in the process of operating the unlocking mechanism to release the locking mechanism, a complex mechanism linkage process must be performed, which is prone to mechanical errors, interference, or loss. . In addition, the conventional pluggable connector has to operate another set of mechanisms to pull the pluggable connector out of the socket after the locking mechanism is released by the unlocking mechanism, resulting in inconvenience and time consuming operation.

In view of the above problems, in one embodiment, a pluggable connector is provided for assembling a socket having a spring arm and a button hole provided on the elastic arm. The pluggable connector includes a body, a snap member and a pull handle structure. The body includes a housing and a plug extending from the housing. The fastening component is disposed on the plug and includes a protrusion protruding from the surface of the plug, and the protrusion is corresponding to the fastening hole of the elastic arm. The handle structure comprises a substrate and a pull handle disposed at one end of the substrate, the substrate is slidably disposed in the outer casing of the body, and the substrate extends to the plug with respect to one end of the pull handle and is provided with a release member corresponding to the elastic arm, when the plug When the socket is inserted into the socket in the first direction and the protrusion is fastened to the buckle hole of the elastic arm, the handle structure is moved to a release position in a second direction opposite to the first direction to drive the release member to press the elastic arm away from the buckle Piece, the bump is removed from the buttonhole.

In summary, the embodiment of the present invention moves through the handle structure in a direction opposite to the insertion of the plug (that is, the direction in which the plug is pulled out of the socket) to release the latching state of the plug and the socket. Therefore, the handle structure can be simultaneously used. The plug is taken out of the socket, and the release and extraction of the plug can be completed by the same member, which is faster and more convenient in operation. In addition, by integrally forming the structure of the handle structure (including the handle, the substrate and the release member), in addition to improving the structural strength of the handle structure itself, simplifying the manufacturing and assembly process, the plug is released and pulled out. In the process, the handle structure does not have to undergo a complicated mechanism linkage process to reduce mechanical errors, interference or loss.

And a release member 23. The substrate 21, the pull handle 22 and the release member 23 are integrally formed. For example, the substrate 21, the pull handle 22 and the release member 23 can be integrally bent and formed by a plate body, or can be integrally molded by a mold, and pulled. The 22 and the release member 23 are respectively disposed at opposite ends of the substrate 21, wherein the substrate 21 is disposed in the casing 11 and placed on the bottom plate 113 so that the substrate 21 can slide in the X-axis direction with respect to the bottom plate 113. The pull handle 22 of the handle structure 20 extends out of the body 10 with respect to one end of the plug 15 and is exposed outside the body 10 for the user to control the sliding of the substrate 21 relative to the outer casing 11.

The release member 23 of the handle structure 20 is a region that passes through the lower casing 117 of the outer casing 11 and extends to the plug 15, where the release member 23 includes a resilient piece 231 extending from the substrate 21 and attached to the end of the elastic piece 231. The pressing plate 232 is provided with an escape hole 2311 extending through the upper and lower surfaces of the elastic piece 231. The bump 161 of the latching member 16 is corresponding to the through hole 2311. In addition, the latching member 16 is provided with a driving slope 162 on one side of the bump 161. As shown in FIG. 4, when the plug 15 of the pluggable connector 1 is inserted into the socket 2, the bump 161 is correspondingly fastened to the socket 2. When the hole 5 is fastened on the arm 4, the driving slope 162 includes a first end adjacent to the protrusion 161 and a second end away from the protrusion 161, and the distance between the first end and the elastic arm 4 is smaller than the second end and the elastic The spacing between the arms 4, the pressing plate 232 of the releasing member 23 is elastically abutted against the driving slope 162 by the elastic piece 231. When the substrate 21 slides relative to the bottom plate 113, the pressing plate 232 is synchronously moved along the driving slope 162. . The operation flow of this embodiment will be described in detail below with reference to the drawings.

Referring to FIG. 3 and FIG. 4, if there is a need to take out the pluggable connector 1, the user can pull the handle 22 of the handle structure 20 so that the handle structure 20 as a whole is opposite to the first direction. The second direction (as indicated by arrow D3) moves relative to the outer casing 11 to simultaneously move the pressure plate 232 along the drive ramp 162 toward the elastic arm 4. As shown in FIG. 6, when the handle structure 20 is moved to a release position, the pressure plate 232 will press the elastic arm 4 downward (as indicated by arrow D2) away from the latching member 16, so that the bump 161 can be disengaged. The hole 5 is buckled to release the pluggable connector 1. At this time, the pluggable connector 1 can be moved relative to the socket 2. In addition, since the handle structure 20 is moved in a direction opposite to the insertion of the plug 15 into the socket 2 (that is, the direction in which the plug 15 is pulled out) to release the snap-fit state of the plug 15 and the socket 2, the handle structure 20 is It can be used simultaneously to take out the plug 15 from the socket 2, and the release and extraction of the plug 15 can be completed by the same member.

In the embodiment, the stopper 111 is a flap which is integrally bent inwardly from the bottom plate 113 of the outer casing 11. The handle structure 20 When in the release position (as shown in FIGS. 6 and 7), it will abut against the stopper 111, so that when the handle structure 20 continues to be pulled in the second direction (as indicated by the arrow D3), it can be synchronized. The body 10 that drives the pluggable connector 1 is moved in the second direction away from the socket 2. Thereby, when the plug 15 of the pluggable connector 1 is inserted into the socket 2, so that the bump 161 is correspondingly fastened to the buttonhole 5 of the elastic arm 4 of the socket 2 (as shown in FIG. 4), the user only needs to pull The handle structure 20 is continuously pulled in the second direction (as indicated by the arrow D2), so that the buckle state of the plug 15 and the socket 2 can be released, and the plug 15 can be pulled out of the socket 2, so that the operation is faster and more convenient. efficacy. In addition, since the handle structure 20 (including the handle 22, the substrate 21, and the release member 23) is integrally designed as an integrally formed structure, in addition to improving the structural strength of the handle structure 20 itself and simplifying the manufacturing and assembly processes, During the release and withdrawal of the plug 15, the handle structure 20 does not have to undergo complicated mechanism linkage processes to reduce mechanical errors, interference or loss.

In some embodiments, the stopper 111 may be additionally fixed (eg, glued, snapped, or) to a stopper on the bottom plate 113 of the outer casing 11. Alternatively, in some embodiments, the pluggable connector 1 can also omit the arrangement of the blocking member 111.

As shown in FIG. 3, during the insertion of the plug 15 of the pluggable connector 1 into the socket 2 in the first direction, the elastic arm 4 can be pressed by the auxiliary piece 233 and moved downward along the guiding slope 2331 (eg The arrow D2 shows that the process of inserting the pluggable connector 1 into the socket 2 can be smoother and avoid the feeling of frustration.

As shown in FIG. 4, in an embodiment, the release member 23 further includes a flap 234 which is superposed on the pressing plate 232 and includes a bending section 235. The flap 234 is a bending section 235. The plate 232 is integrally connected to the pressing plate 232. In other words, the folding plate 234 is integrally bent and bent from the end of the pressing plate 232, and the bending portion 235 abuts against the driving slope 162 (that is, the pressing plate 232 is indirectly abutted against the driving inclined surface via the folding plate 234). 162)). Thereby, when the handle structure 20 moves toward the outer casing 11 in the second direction (as indicated by arrow D3) to drive the pressure plate 232 along the driving ramp 162 to move the elastic arm 4, the bending section 235 can be used. The guiding is smoother to avoid excessive friction between the pressure plate 232 and the driving ramp 162, which affects the operation feel and effect.

As shown in FIG. 2 and FIG. 3, in the embodiment, a housing 12 is further disposed in the outer casing 11 of the body 10. For example, the clamping plate 12 can be adhered or fastened in the outer casing 11 to form a gap between the clamping plate 12 and the bottom plate 113. The interlayer 21 of the handle structure 20 is sandwiched between the clamping plate 12 and the bottom plate 113. For example, the gap between the clamping plate 12 and the bottom plate 113 may be slightly larger than the thickness of the substrate 21, so that the handle structure 20 slides relative to the outer casing 11. There is no sway or detachment from the casing 11 during the movement. In an embodiment, the handle structure 20 can also directly receive the limit by the pull handle 22 against the outer casing 11 and the elastic piece 231 against the buckle member 16, that is, the pull handle 22 and the elastic piece 231 can directly fit the outer casing 11 And the latching member 16 is used as a member of the limiting substrate 21 without additionally adding a splint 12 or other structure for limiting the substrate 21. The embodiment of the embodiment is omitted.

Referring to FIG. 3, FIG. 4 and FIG. 5, an elastic returning member 14 is further disposed in the outer casing 11 of the pluggable connector 1. The elastic returning member 14 is coupled to the substrate 21 and the outer casing 11 to provide an elastic preload. The handle structure 20 can be returned from the release position to the initial position in the first direction. In this embodiment, the elastic returning member 14 is a spring, and the bottom plate 113 of the outer casing 11 is integrally bent upwardly with a first hook 114, and the base plate 21 is integrally bent upward to form a second hook 212, and one end of the elastic returning member 14 The sleeve is positioned on the first hook 114, and the other end of the elastic return member 14 is sleeved and positioned on the second hook 212. Thereby, as shown in FIG. 5 and FIG. 7, when the handle structure 20 is forced to move to the release position (as shown in FIG. 7) in the second direction, the elastic return member 14 is stretched to generate elasticity. The preload force enables the handle structure 20 to return to the original initial position (as shown in FIG. 5) by the elastic preload of the elastic return member 14, thereby achieving the effect of increasing the convenience of use.

As shown in FIG. 3, FIG. 4 and FIG. 5, a limiting member 112 is further disposed in the outer casing 11 of the body 10. In the embodiment, the limiting member 112 is integrally bent inwardly from the bottom plate 113 of the outer casing 11. The flaps are spaced closer to the plug 15 relative to the stops 111. When the handle structure 20 is in the initial position, it abuts against the limiting member 112, that is, when the handle structure 20 is forced to move to the releasing position in the second direction (as shown in FIG. 7), the drawing structure is stretched. The elastic return member 14 generates an elastic preload force. When the handle structure 20 is unstressed, the elastic preload force of the elastic return member 14 can be restored to the initial position (as shown in FIG. 5) and the handle structure 20 is Positioning is obtained by abutting against the stopper 112.

In addition, as shown in FIG. 2, FIG. 5 and FIG. 7, the substrate 21 of the handle structure 20 is further integrally provided with two interference pieces 211. For example, the interference pieces 211 and the substrate 21 are integrally bent by a plate body or It is integrally molded by a mold. The two interference pieces 211 are respectively located on two sides of the substrate 21 and extend in the X-axis direction, and the interference pieces 211 are respectively outwardly pressed against the inner side of the outer casing 11, so that the handle structure 20 can be more moved when moving relative to the outer casing 11. Stabilized, and during the movement of the handle structure 20, an interference friction force is generated between the interference piece 211 and the outer casing 11, preventing the speed or force of the movement of the handle structure 20 from being excessive to impact or wear other members.

FIG. 8 is a partial cross-sectional view showing a second embodiment of the pluggable connector of the present invention. The difference between the embodiment and the first embodiment is that the latching member 16 of the pluggable connector 1A includes only the bumps 161, and the releasing member 23 includes a resilient piece 231 and a pressing block 236 extending from the substrate 21. Further, the pressing block 236 is bent by the end of the elastic piece 231 in a direction away from the plug 15 and superposed on the elastic piece 231. When the plug 15 of the pluggable connector 1 is inserted into the socket 2 so that the bump 161 is correspondingly fastened to the buttonhole 5 of the elastic arm 4 of the socket 2, the pressing block 236 directly opposes the elastic arm 4 when the handle is pulled. When the structure 20 is moved opposite to the direction in which the plug 15 is inserted into the socket 2 (that is, the direction in which the plug 15 is pulled out), the pressing block 236 directly presses the elastic arm 4 away from the latching member 16 to disengage the bump 161 from the buckle hole 5 The function of releasing the pluggable connector 1A is achieved.

9 is a partial cross-sectional view showing a third embodiment of the pluggable connector of the present invention. The difference between the embodiment and the first embodiment is that the elastic returning member 14A of the pluggable connector 1B is two elastic pieces and is integrally extended from two sides of the substrate 21, for example, the elastic returning member 14A and the substrate 21 can be separated by a The plate body is integrally formed by bending, or is integrally molded by a mold, and the end of the elastic returning member 14A is fixed to the outer casing 11. In the embodiment, the outer casing 11 is further convexly provided with two convex ribs 115, and the elastic The end of the reset member 14A is abutted against the rib 115, or, in some embodiments, the elastic return member 14A can also be adhesively or snap-fitted to the shell wall of the outer casing 11 to move the release plug 15 in the handle structure 20. During the process, the elastic return member 14A can provide an elastic restoring force. Therefore, in the embodiment, by designing the elastic returning member 14A and the handle structure 20 as an integrally formed structure, the advantages of increasing structural strength and simplifying the process can be further achieved.
