Description

Technical Field

[0001] This invention relates to a plug anti-pull-out device. Background Technology

[0002] Modern PDUs are modular, typically consisting of a housing and connector modules housed within it. Each connector module is secured to the housing with snap-fit ​​mechanisms. The specific connection structure is as follows: the housing has an opening at the top, and the connector modules have through holes on their two opposite sidewalls. Each through hole contains an outward-extending spring tab, with its top extending outwards and its bottom fixed to the inner wall of the through hole. During installation, the connector module is inserted through the opening. The spring tab contacts the inner wall of the opening from its bottom. Upon compression, the spring tab retracts into the through hole until it has completely passed through the connector. The spring tab then springs back to its original elasticity, preventing the connector module from being pulled out.

[0003] To allow space for the elastic module to recover its elasticity, the distance between the cover plate and the spring clip at the top of the socket module must be greater than the thickness at the opening. In other words, after the socket modules are installed, there is still a certain gap between them in the longitudinal direction.

[0004] The plug that mates with the PDU has a step at one end when it is inserted into the socket module.

[0005] How to make the existing PDU and its plug have the function of preventing them from being pulled out is a problem. Summary of the Invention

[0006] The purpose of this invention is to provide a plug anti-pull-out device that can lock the plug on existing PDUs.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention provides a plug anti-pull-out device, comprising a housing, a socket module, and a plug. The housing has an opening, the socket module has a cover plate on its top, and first through holes on both sides of the socket module. A first spring piece is disposed within each of the first through holes, with its top extending outwards and its bottom fixed within the first through hole. The bottom of the socket module is inserted into the housing from the opening until the cover plate abuts against the opening. The plug is inserted and fixed onto the socket module. The plug has a step and includes two latches disposed on opposite end faces of the socket module. Each latch includes a connecting block and a clamping block. The connecting block has a groove, and the clamping block is slidably connected within the groove. The bottom of the connecting block has a protruding insert that inserts into the gap between the socket module and the housing. The clamping block presses against the step on the plug. In use, first insert the connecting blocks on the two clips along the gap into the insert to complete the installation of the connecting blocks. Then, insert the clamping block into the slide groove and push it towards the center until the clamping block presses down on top of the plug. This way, when the plug is pulled out, it will be pressed down by the clamping block, and the clamping block's vertical position is limited by the connecting blocks, which are then locked in place at the gap, preventing the plug from being pulled out. This structure allows us to prevent the plug from being pulled out without modifying the existing equipment.

[0008] Furthermore, the locking block is provided with a second through hole, and a second spring piece is provided inside the second through hole. An upward protrusion is provided on the inner end of the second spring piece, extending out of the second through hole. The outer end of the second spring piece is connected to the second through hole. The connecting block is provided with a strip groove, and the protrusion is located within the strip groove. When the locking block is pulled out, the protrusion will abut against the groove. This abutment increases the difficulty of pulling the locking block out of the groove, preventing the locking block from being easily pulled out and causing the plug lock to be canceled. Of course, if the force applied to the locking block reaches a certain level, the second spring piece can also undergo elastic deformation, causing the protrusion to retract into the second through hole, at which point the locking block can be pulled out.

[0009] Furthermore, each of the clamping pieces has two second spring pieces.

[0010] Furthermore, the latches are located at both ends of the socket module at the edge of the housing. This design ensures that installing the latches will not affect adjacent socket units.

[0011] Furthermore, the connecting block includes a body, with a protrusion at the bottom of the body, and the insert is disposed at the bottom of the protrusion, the insert and the body clamping the cover plate.

[0012] The present invention has the following beneficial effects: By setting up a partition plate, which is connected to the grooves, slots, connecting grooves, and openings in the cover plate via sealing gaskets, buckles, connecting posts, and movable plates, the partition plate can be locked into the connecting groove in the cover plate via the connecting posts. During use, the partition plate can be quickly opened to inspect and repair the faulty part separately, avoiding the cumbersome process of disassembly and installation. It also reduces the risk of other parts being exposed to the air or being accidentally touched. This not only saves a lot of maintenance time but also helps protect the plug anti-pull-out device, which is beneficial to the use of the plug anti-pull-out device in real life.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] A plug anti-pull-out device includes a housing 1, a socket module 2 and a plug 3, wherein the housing 1 is provided with an opening 11.

[0022] The socket module 2 has a cover plate 21 on its top, and first through holes 22 are provided on both sides of the socket module 2. A first spring piece 23 is provided in the first through hole 22, the top of the first spring piece 23 protruding outward, and the bottom of the first spring piece 23 being fixed in the first through hole 22. The bottom of the connector module 2 is inserted into the housing 1 from the opening 11 until the cover plate 21 abuts against the opening 11.

[0023] The plug 3 is inserted and fixed on the socket module 2, and the plug 3 has a step 31.

[0024] It also includes two latches 4, which are disposed on opposite end faces of the socket module 2. In this embodiment, the latches 4 are disposed at both ends of the socket module 2 located at the edge of the housing 1. This arrangement ensures that installing the latches will not affect adjacent socket units.

[0025] The buckle 4 includes a connecting block 41 and a clamping block 42. The connecting block 41 is provided with a sliding groove 411, and the clamping block 42 is slidably connected in the sliding groove 411. The bottom of the connecting block 41 has a protruding insert 412, which is inserted into the gap between the socket module 2 and the housing 1. The clamping block 42 presses against the step 31 on the plug 3. The connecting block 41 includes a body 4a, and a protruding part 4b is provided below the body. The insert 412 is located at the bottom of the protruding part 4b, and the insert 412 and the body 1 clamp the cover plate 21.

[0026] The locking block 42 is provided with a second through hole 421, and a second spring piece 422 is provided inside the second through hole 421. There are two second spring pieces 422 on each locking block 42. The inner end of the second spring piece 422 is provided with an upward protrusion 423, which extends out of the second through hole 421. The outer end of the second spring piece 422 is connected to the second through hole 421. The connecting block 41 is provided with a strip groove 413, and the protrusion 423 is located in the strip groove 413. When the locking block is pulled out, the protrusion will abut against the groove. This abutment increases the difficulty of pulling the locking block out of the groove, preventing the locking block from being easily pulled out and causing the plug lock to be canceled. Of course, if the force applied to the locking block reaches a certain level, the second spring piece can also undergo elastic deformation, causing the protrusion to retract into the second through hole, at which point the locking block can be pulled out.

[0027] In use, first insert the connecting blocks on the two clips along the gap into the insert to complete the installation of the connecting blocks. Then, insert the clamping block into the slide groove and push it towards the center until the clamping block presses down on top of the plug. This way, when the plug is pulled out, it will be pressed down by the clamping block, and the clamping block's vertical position is limited by the connecting blocks, which are then locked in place at the gap, preventing the plug from being pulled out. This structure allows us to prevent the plug from being pulled out without modifying the existing equipment.
