Description

connector Technical Field

[0001] This disclosure relates to connectors, and in particular to an easy-to-operate through-wall locking connector. Prior Technology

[0002] In the field of electronic equipment and electrical connection technology, through-wall locking is often used to fix connectors to equipment housings or mounting panels. This involves a hook on the connector that passes through the panel and is locked in place by a locking mechanism. One existing locking mechanism uses a rotary drive for locking. Its operating principle involves rotating a gear structure. When the user rotates the gear, the gear structure pushes the hook to engage with the panel, and the gear simultaneously engages the hook with its teeth until the hook and the edge of the panel are pressed together, thus completing the locking process. To disassemble (unlock), the operator must rotate the gear in the opposite direction to retract the hook back to its original position. This structure typically occupies a large space to allow for rotation, which is not conducive to miniaturization or high-density installation of equipment. Furthermore, the structure and connector usually need to be located on opposite sides of the panel, requiring the operator to access the gear from the back of the panel during installation or maintenance, which is quite inconvenient.

[0003] In view of this, the creator has devoted himself to studying the aforementioned existing technologies and applying theoretical principles to try his best to solve the problems mentioned above, which has become the creator's goal for improvement. Summary of the Invention

[0029] The detailed description and technical content of this disclosure will be explained in conjunction with the following drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this disclosure.

[0030] Figure 1 is a perspective view of the connector of the first embodiment. Figure 2 is a cross-sectional view of the connector of the first embodiment. Figure 3 is a perspective view of the connector of the first embodiment. Referring to Figures 1 to 3, the first embodiment provides an easy-to-operate through-wall locking connector, which includes an insulating body 100 and at least one locking member 200.

[0031] The insulating body 100 is a generally rectangular block. The insulating body 100 has a bottom 101, and at least one groove 102 and a plurality of slots 104 for inserting conductive wires are formed within it. In this embodiment, a pair of grooves 102 are formed within the insulating body 100, and a locking member 200 is respectively provided in each groove 102. However, the number of grooves 102 is not limited. In the simplest embodiment, a single groove 102 combined with a single locking member 200 can achieve the locking effect. The following description uses only one groove 102 and the locking member 200 inserted therein as an example to illustrate other related structures. The other groove 102 and the locking member 200 inserted therein have the same structure.

[0032] One end of the slide groove 102 is a bottom end, which connects to the bottom 101 of the insulating body 100. At least one actuating channel 103 is provided on the insulating body 100 corresponding to the slide groove 102, and the actuating channel 103 penetrates the side wall of the insulating body 100 and connects to the slide groove 102. At least one positioning part 110 is provided around the bottom 101 of the insulating body 100. The positioning part 110 can be located on the bottom surface of the insulating body 100 or on a protrusion protruding from the insulating body 100. In this embodiment, the positioning part 110 is a planar stop, and the positive direction of the positioning part 110 is the same as the opening direction (outward) of the slide groove 102 on the bottom 101 of the insulating body 100.

[0033] In this embodiment, a pair of actuating channels 103 are provided on two opposite sides of the slide 102, and the longitudinal direction of each actuating channel 103 is parallel to the longitudinal direction of the slide 102. Each slide 102 of the insulating body 100 is provided with a pair of spring arm hooks 120. Each spring arm hook 120 is located at the bottom end of the slide 102 and extends through the bottom 101 of the insulating body 100, and the pair of spring arm hooks 120 are respectively arranged on opposite sides of the slide 102. The inner side of each spring arm hook 120 is provided with an actuating slope 123, and the pair of actuating slopes 123 of the pair of spring arm hooks 120 are arranged facing each other. In this embodiment, the number of spring arm latches 120 and positioning parts 110 is the same, and each spring arm latch 120 is configured corresponding to one of the positioning parts 110. However, this disclosure is not limited to this. When the number of spring arm latches 120 and positioning parts 110 is different, multiple spring arm latches 120 may also correspond to the same positioning part 110. In the simplest embodiment, a single spring arm latch 120 combined with a single positioning part 110 can achieve the effect of clamping and fixing.

[0034] Referring to Figures 1 and 2, the locking member 200 passes through the slide groove 102 and can slide longitudinally relative to the insulating body 100. The locking member 200 includes a sliding pin 201 and at least one pawl 230. The sliding pin 201 has an actuating end 2011 and an operating end 2012. The actuating end 2011 is configured corresponding to the bottom 101 of the insulating body 100, and the operating end 2012 protrudes from the top of the insulating body 100 opposite to the bottom 101. The top surface of the operating end 2012 is provided with anti-slip texture to increase the tactile feel and force stability when the user presses with their fingers. The pawl 230 is configured on one side of the sliding pin 201 for hooking the inner wall of the slide groove 102. In this embodiment, a pair of identical pawls 230 are provided, and the pair of pawls 230 are respectively configured on opposite sides of the sliding pin 201.

[0035] Specifically, a pair of release spring arms 220 extend upward from the two opposite sides of the sliding pin 201 toward the operating end 2012. Each release spring arm 220 extends upward to a free end 221, and an operating part 222 is provided on the free end 221. The operating part 222 protrudes from the insulating body 100 through the actuation channel 103 through the side wall of the sliding groove 102. The outer surface of the operating part 222 may also be provided with wavy anti-slip textures for easy gripping. A pair of pawls 230 are respectively provided on the outer side of the pair of release spring arms 220. An elastic structure 240 is connected between the free end 221 of the release spring arm 220 and the central body of the sliding pin 201. In this embodiment, the elastic structure 240 is a compression spring formed by bending elastic arms.

[0036] On the inner wall of the slide groove 102 of the insulating body 100, a shank 130 is provided corresponding to the position of each pawl 230, and the pawl 230 can engage with the shank 130. The shank 130 includes a plurality of alternating teeth 131 and grooves 132. Each tooth 131 has a forward slope 133 and a locking plane 134 on each side. That is, the forward slope 133 and the locking plane 134 are arranged facing each other within each groove 132. The forward slope 133 is inclined relative to the longitudinal direction of the slide groove 102 and faces away from the bottom 101 of the insulating body 100. The locking plane 134 is perpendicular to the longitudinal direction of the slide groove 102 to stop the pawl 230. The acute angle between each forward slope 133 and the adjacent locking plane 134 is between 35 degrees and 45 degrees, for example, 40 degrees.

[0037] The actuating end 2011 of the locking member 200 has a pressing structure 210, which is a pair of protrusions provided on two opposite side edges of the actuating end 2011. A guide slope 211 is provided on the side edge of the actuating end 2011 of the sliding pin 201, which is adjacent to the pressing structure 210.

[0038] Figure 4 is a cross-sectional view of one usage state of the connector according to the first embodiment of the present disclosure. Figure 5 is another cross-sectional view of the connector according to the first embodiment of the present disclosure. Figure 6 is yet another cross-sectional view of the connector according to the first embodiment of the present disclosure. Referring to Figure 4, when the insulating body 100 is disposed on one side of a panel 10, its spring arm latch 120, when passing through the through-hole 11, pushes against the inner edge of the through-hole 11 with its locking slope 121, causing the spring arm latch 120 to elastically deform and retract, thereby allowing the spring arm latch 120 to pass through the through-hole 11. Referring to Figure 5, after the spring arm latch 120 passes through the through-hole 11 and through the panel 10, it resets, clamping the inner edge of the through-hole 11 between the spring arm latch 120 and the positioning part. This positions the insulating body 100 on the panel 10.

[0039] Referring to Figures 5 and 6, after the insulating body 100 is positioned on the panel 10, the user can press down on the operating end 2012 of the locking member 200 to lock the spring arm hooks 120. When the locking member 200 slides towards the bottom 101, the guide slope 211 of its actuating end 2011 will first contact and slide over the actuating slope 123 of the spring arm hooks 120. Then, the pressing structure 210 pushes against the actuating slope 123, forcibly opening the pair of spring arm hooks 120, causing them to move outward (left and right sides) of the slide groove 102 and approach the positioning part 110. At this time, the locking slope 121 and the anti-slip teeth 122 on the outer side of the spring arm hooks 120 will press tightly against the inner edge of the opening 11, so that the panel 10 is firmly clamped between the spring arm hooks 120 and the positioning part 110. During the downward pressing of the locking member 200, the pawl 230 slides downward tooth by tooth along the forward slope 133 of the ratchet 130. Referring to Figure 6, when the pressing stops, the pawl 230 engages with the locking plane 134 of the ratchet 130, preventing the locking member 200 from retracting upward due to the elastic reaction force of the spring arm hook 120, thus ensuring the stability of the locking state.

[0040] Referring to Figures 1 and 6, a locking slope 121 is provided at the barb on the outer side of the spring arm hook 120. The locking slope 121 is further provided with a plurality of anti-slip teeth 122 to increase the friction with the inner edge of the opening 11 of the panel 10 and prevent the spring arm hook 120 from slipping off.

[0041] Referring to Figure 6, when the connector is to be removed from the panel 10, the user presses (pinches) the pair of operating parts 222 inward from both sides of the insulating body 100. This action compresses the elastic structure 240, causing the unlocking spring arms 220 on both sides to retract inward, driving the pawl 230 to disengage from the locking plane 134 of the ratchet 130, thereby releasing the inner wall of the slide groove 102. While holding the operating parts 222 pressed, the user can pull the slide pin 201 upward, causing the pressing structure 210 of the actuating end 2011 to retract upward from the actuating slope 123 of the spring arm hook 120. Once the opening force of the pressing structure 210 is lost, the pair of spring arm hooks 120 will reset by their own elastic force and move away from the positioning part 110. At this time, the inner edge of the panel 10 opening 11 pushing against the locking slope 121 can also assist the spring arm hooks 120 to retract, allowing them to smoothly disengage from the opening 11, completing the unlocking and disassembly operation.

[0042] The connector disclosed herein has a locking member 200 extending through both sides of the insulating body 100, thus facilitating operation of the locking member 200 to lock or release the insulating body 100.

[0043] Figure 7 is a perspective view of the connector according to the second embodiment of the present disclosure. Figure 8 is a cross-sectional view of the connector according to the second embodiment of the present disclosure. Figure 9 is a cross-sectional view of the connector according to the second embodiment of the present disclosure in one usage state. Figure 10 is another cross-sectional view of the connector according to the second embodiment of the present disclosure in another usage state. Figure 11 is yet another cross-sectional view of the connector according to the second embodiment of the present disclosure in yet another usage state. Referring to Figures 7 to 11, the second embodiment provides an easy-to-operate through-wall locking connector, which includes an insulating body 100 and at least one locking member 200.

[0044] The insulating body 100 is a generally rectangular block. The insulating body 100 has a bottom 101, and at least one groove 102 and a plurality of slots 104 for inserting conductive wires are formed within it. In this embodiment, a pair of grooves 102 are formed within the insulating body 100, and a locking member 200 is provided in each groove 102. However, the number of grooves 102 is not limited; in the simplest embodiment, a single groove 102 combined with a single locking member 200 is sufficient to achieve the locking effect.

[0045] This description focuses on one of the slides 102 as an example; the other slide 102 has the same structure. One end of the slide 102 is a bottom end, which connects to the bottom 101 of the insulating body 100. At least one actuating channel 103 is provided on the insulating body 100 corresponding to this slide 102, penetrating the side wall of the insulating body 100 and connecting to the slide 102. At least one positioning part 110 is provided around the bottom 101 of the insulating body 100. The positioning part 110 can be located on the bottom surface of the insulating body 100 or on a protrusion protruding from the insulating body 100. In this embodiment, the positioning part 110 is a planar stop, and the positive direction of the positioning part 110 is the same as the opening direction (outward) of the slide 102 on the bottom 101 of the insulating body 100. In this embodiment, a pair of actuation channels 103 are provided on two opposite sides of the slide 102, and the longitudinal direction of each actuation channel 103 is parallel to the longitudinal direction of the slide 102.

[0046] Each insulating body 100 is provided with a spring-loaded hook 120 corresponding to each slide groove 102, and the pair of spring-loaded hooks 120 are respectively arranged on the aforementioned opposite sides of the insulating body 100. The spring-loaded hook 120 is located at the bottom end of the slide groove 102 and extends through one side of the bottom 101 of the insulating body 100. Each spring-loaded hook 120 has a matching actuating slope 123 on its inner side, and the pair of actuating slopes 123 of the pair of spring-loaded hooks 120 are arranged facing each other. In this embodiment, the number of spring-loaded hooks 120 and positioning parts 110 is the same, and each spring-loaded hook 120 is respectively arranged corresponding to at least one of the positioning parts 110. Specifically, each spring-loaded hook 120 corresponds to multiple positioning parts 110. In the simplest embodiment, a single spring-loaded hook 120 combined with a single positioning part 110 can achieve the effect of clamping and fixing.

[0047] The following description uses only one slide groove 102 and the locking member 200 inserted therein as an example to illustrate other related structures. The other slide groove 102 and the locking member 200 inserted therein have the same structure. The locking member 200 passes through the slide groove 102 and can slide longitudinally relative to the insulating body 100. The locking member 200 includes a sliding pin 201 and at least one pawl 230. The sliding pin 201 has an actuating end 2011 and an operating end 2012. The actuating end 2011 is configured corresponding to the bottom 101 of the insulating body 100, and the operating end 2012 protrudes from the top of the insulating body 100 opposite to the bottom 101. The top surface of the operating end 2012 is provided with anti-slip texture to increase the tactile feel and stability of the force applied when the user presses with their fingers. Pawl 230 is disposed on one side of sliding pin 201 for hooking the inner wall of sliding groove 102. In this embodiment, a pair of identical pawls 230 are provided, and the pair of pawls 230 are respectively disposed on opposite sides of sliding pin 201.

[0048] Specifically, a pair of release spring arms 220 extend upward from the two opposite sides of the sliding pin 201 toward the operating end 2012. Each release spring arm 220 extends upward to a free end 221, and an operating part 222 is provided on the free end 221. The operating part 222 protrudes from the insulating body 100 through the actuation channel 103 through the side wall of the sliding groove 102. The outer surface of the operating part 222 may also be provided with wavy anti-slip textures for easy gripping. A pair of pawls 230 are respectively provided on the outer side of the pair of release spring arms 220. An elastic structure 240 is connected between the free end 221 of the release spring arm 220 and the central body of the sliding pin 201. In this embodiment, the elastic structure 240 is a compression spring formed by bending elastic arms.

[0049] On the inner wall of the slide groove 102 of the insulating body 100, a shank 130 is provided corresponding to the position of each pawl 230, and the pawl 230 can engage with the shank 130. The shank 130 includes a plurality of alternating teeth 131 and grooves 132. Each tooth 131 has a forward slope 133 and a locking plane 134 on each side. That is, the forward slope 133 and the locking plane 134 are arranged facing each other within each groove 132. The forward slope 133 is inclined relative to the longitudinal direction of the slide groove 102 and faces away from the bottom 101 of the insulating body 100. The locking plane 134 is perpendicular to the longitudinal direction of the slide groove 102 to stop the pawl 230. The acute angle between each forward slope 133 and the adjacent locking plane 134 is between 35 degrees and 45 degrees, for example, 40 degrees.

[0050] The actuating end 2011 of the locking member 200 has a pressing structure 210, which is a pair of protrusions provided on two opposite side edges of the actuating end 2011. A guide slope 211 is provided on the side edge of the actuating end 2011 of the sliding pin 201, which is adjacent to the pressing structure 210.

[0051] When the insulating body 100 is disposed on one side of a panel 10, its spring-loaded latch 120, when passing through the through-hole 11, pushes against the inner edge of the through-hole 11 with its locking slope 121, causing the spring-loaded latch 120 to elastically deform and retract, thereby allowing the spring-loaded latch 120 to pass through the through-hole 11. Referring to Figures 9, 10, and 11, after the spring-loaded latch 120 passes through the through-hole 11 and through the panel 10, it resets, clamping the inner edge of the through-hole 11 between the spring-loaded latch 120 and the positioning part. This positions the insulating body 100 on the panel 10.

[0052] Referring to Figures 9, 10, and 11, after the insulating body 100 is positioned on the panel 10, the user can press down on the operating end 2012 of the locking member 200 to lock the spring arm hooks 120. When the locking member 200 slides towards the bottom 101, the guide slope 211 of its actuating end 2011 will first contact and slide over the actuating slope 123 of the spring arm hooks 120. Then, the pressing structure 210 pushes against the actuating slope 123, forcibly opening the pair of spring arm hooks 120, causing them to move outward (left and right sides) of the slide groove 102 and approach the positioning part 110. At this time, the locking slope 121 on the outside of the spring arm hooks 120 will press tightly against the inner edge of the opening 11, so that the panel 10 is firmly clamped between the spring arm hooks 120 and the positioning part 110. During the downward pressing of the locking member 200, the pawl 230 slides downward tooth by tooth along the forward slope 133 of the ratchet 130. Referring to Figures 9, 10, and 11, when the pressing stops, the pawl 230 engages with the locking plane 134 of the ratchet 130, preventing the locking member 200 from retracting upward due to the elastic reaction force of the spring arm hook 120, thus ensuring the stability of the locking state.

[0053] The outer side of the spring arm hook 120 is provided with a locking slope 121, and the locking slope 121 is further provided with a plurality of anti-slip teeth 122 to increase the friction with the inner edge of the opening 11 of the panel 10 and prevent the spring arm hook 120 from slipping off.

[0054] When removing the connector from the panel 10, the user presses (pinches) the pair of operating parts 222 inward from both sides of the insulating body 100. This action compresses the elastic structure 240, causing the unlocking arms 220 on both sides to retract inward, driving the pawl 230 to disengage from the locking plane 134 of the ratchet 130, thereby releasing the inner wall of the slide groove 102. While holding the operating parts 222 pressed, the user can pull the slide pin 201 upward, causing the pressing structure 210 of the actuating end 2011 to retract upward from the actuating slope 123 of the spring arm hook 120. Once the opening force of the pressing structure 210 is lost, the pair of spring arm hooks 120 will reset by their own elastic force and move away from the positioning part 110. At this time, the inner edge of the panel 10 opening 11 pushing against the locking slope 121 can also assist the spring arm hooks 120 to retract, allowing them to smoothly disengage from the opening 11, completing the unlocking and disassembly operation.

[0055] The above description is merely a preferred embodiment of this invention and is not intended to limit the patent scope of this invention. Other equivalent variations that utilize the patent spirit of this invention should also fall within the patent scope of this invention.
