Detailed implementation manners

[0048] To make the purpose, technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the drawings.

[0049] For a converter product with a movable plug component developed by our company, during the handboard sample test stage, it was found that there was a large gap between the slidable plug component and the converter housing, making the sliding of the plug component too loose and posing a great potential safety hazard. Moreover, due to the existence of the gap, dust, water or other foreign objects may enter, reducing the reliability of the converter.

[0050] To solve the above technical problems, the embodiments of the present disclosure provide a converter. Figure 1 and Figure 2 is a structural schematic diagram of the converter. Figure 1 and Figure 2 have opposite perspectives. Combining Figure 1 and Figure 2 , in this embodiment, the converter includes a housing 10, a partition board 20, a plug component 30 and a protection component 40.

[0051] The housing 10 includes a connected first housing 110 and a second housing 120. The second housing 120 has a sliding hole 121. The partition 20 and the latch assembly 30 are sequentially located between the first housing 110 and the second housing 120, and the latch assembly 30 is movably located in the sliding hole 121. The protection assembly 40 is located between the partition 20 and the second housing 120, and the protection assembly 40 is arranged around the sliding hole 121 to block the gap between the second housing 120 and the partition 20.

[0052] Since the latch assembly 30 is movably located in the sliding hole 121 of the second housing 120, it can move within the housing 10. Thus, when plugging, the latch assembly 30 can move to a suitable position, improving the convenience and applicability of the converter during use. Since a protection assembly 40 is provided between the partition 20 and the second housing 120, and the protection assembly 40 is arranged around the sliding hole 121, under the action of the protection assembly 40, the gap between the second housing 120 and the partition 20 can be blocked, thus preventing dust from entering the interior of the housing 10 through the gap between the second housing 120 and the partition 20, and effectively improving the protection ability of the converter.

[0053] That is to say, even though the second housing 120 is provided with a sliding hole 121 for the latch assembly 30 to slide, under the shielding of the protection assembly 40, dust cannot enter the interior of the housing 10 through the gap between the second housing 120 and the partition 20, effectively improving the protection ability of the converter.

[0054] In this embodiment, the first housing 110 and the second housing 120 are detachably connected to each other by a snap - fit method. After the first housing 110 and the second housing 120 are connected, a space is formed that can accommodate the partition 20, the latch assembly 30, and the protection assembly 40, thus providing a reliable protection and installation carrier.

[0055] As can be seen from the foregoing, the protection assembly 40 is the key to improving the protection ability of the converter. The protection assembly 40 will be introduced below.

[0056] Figure 3 For the assembly schematic diagram between the latch assembly 30 and the second housing 120, combined with Figure 3 , in this embodiment, the protection assembly 40 includes at least two static dust - proof arms 410 and at least two dynamic dust - proof arms 420. The static dust - proof arms 410 are connected to the side of the second housing 120 facing the first housing 110. The dynamic dust - proof arms 420 are connected to the latch assembly 30 and are in sliding contact with the partition 20, and the dynamic dust - proof arms 420 can move relative to the static dust - proof arms 410.

[0057] The protection component 40 is composed of a static dust-proof arm 410 and a dynamic dust-proof arm 420. The static dust-proof arm 410 is connected to the second housing 120 and can block the gap between the second housing 120 and the partition 20. Since the pin assembly 30 needs to move relative to the second housing 120, and during the movement of the pin assembly 30, the gap between the second housing 120 and the partition 20 will change. Therefore, only setting the static dust-proof arm 410 cannot completely block the gap between the second housing 120 and the partition 20. Thus, a dynamic dust-proof arm 420 is provided on the pin assembly 30. The dynamic dust-proof arm 420 can move relative to the static dust-proof arm 410, thereby playing a supplementary blocking role, so that no matter where the pin assembly 30 moves to, the gap between the second housing 120 and the partition 20 can be completely blocked.

[0058] Exemplarily, one side of the static dust-proof arm 410 facing away from the second housing 120 abuts against the partition 20, and one side of the dynamic dust-proof arm 420 facing the second housing 120 is in sliding contact with the second housing 120.

[0059] In the above implementation, one side of the static dust-proof arm 410 is connected to the second housing 120, and the other side abuts against the partition 20, thereby effectively ensuring the blocking of the gap between the second housing 120 and the partition 20 by the static dust-proof arm 410. One side of the dynamic dust-proof arm 420 is in sliding contact with the partition 20, and the other side of the dynamic dust-proof arm 420 is in sliding contact with the second housing 120, thereby effectively ensuring the blocking of the gap between the second housing 120 and the partition 20 by the dynamic dust-proof arm 420.

[0060] Continue to refer to Figure 3 In this embodiment, the static dust-proof arms 410 are located at both ends in the length direction of the sliding hole 121. The dynamic dust-proof arms 420 are located on both sides in the length direction of the sliding hole 121, and the movement trajectories of the dynamic dust-proof arms 420 are spaced apart from the static dust-proof arms 410.

[0061] In the above implementation, since the dynamic dust-proof arms 420 can move along the length direction of the sliding hole 121 together with the pin assembly 30, setting the dynamic dust-proof arms 420 on both sides in the length direction of the sliding hole 121 can enable the dynamic dust-proof arms 420 to always block both sides in the length direction of the sliding hole 121 while moving with the pin assembly 30. And the static dust-proof arms 410 are fixed at both ends in the length direction of the sliding hole 121 to block both ends in the length direction of the sliding hole 121. Moreover, since the movement trajectories of the dynamic dust-proof arms 420 are spaced apart from the static dust-proof arms 410, the dynamic dust-proof arms 420 will not interfere and collide with the static dust-proof arms 410 during the movement, effectively ensuring the reliability of the protection component 40.

[0062] For example, the number of static dust-proof arms 410 is two, and the number of dynamic dust-proof arms 420 is two. One static dust-proof arm 410 is located at one end of the sliding hole 121 in the length direction, and the other static dust-proof arm 410 is located at the other end of the sliding hole 121 in the length direction. One dynamic dust-proof arm 420 is located on one side of the sliding hole 121 in the length direction, and the other dynamic dust-proof arm 420 is located on the other side of the sliding hole 121 in the length direction.

[0063] Exemplarily, the length direction of the static dust-proof arm 410 is perpendicular to the length direction of the sliding hole 121, and the length direction of the dynamic dust-proof arm 420 is parallel to the length direction of the sliding hole 121.

[0064] In the above implementation, by designing the arrangement of the static dust-proof arm 410, the dynamic dust-proof arm 420 and the sliding hole 121 in this way, it is not only convenient for the arrangement of the static dust-proof arm 410 and the dynamic dust-proof arm 420, but also can ensure that the static dust-proof arm 410 and the dynamic dust-proof arm 420 block the gap between the second housing 120 and the partition 20.

[0065] Figure 4 For the assembly schematic diagram between the bolt assembly 30 and the partition 20, combined with Figure 4 , in this embodiment, one side of the partition 20 facing the protection assembly 40 has a guide groove 210, and the length direction of the guide groove 210 is the same as the length direction of the sliding hole 121. At least two of the dynamic dust-proof arms 420 include a guide arm 421, and the length direction of the guide arm 421 is the same as the length direction of the sliding hole 121, and the guide arm 421 is movably located in the guide groove 210.

[0066] In the above implementation, one of the two dynamic dust-proof arms 420 is the guide arm 421. Through the mutual cooperation between the guide arm 421 and the guide groove 210, the bolt assembly 30 can be guided so that its moving direction is always along the length direction of the sliding hole 121. In this way, it can also ensure that the moving direction of the dynamic dust-proof arm 420 connected to the bolt assembly 30 is always along the length direction of the sliding hole 121 to ensure its blocking of the gap between the second housing 120 and the partition 20.

[0067] In this embodiment, one side edge of the partition 20 has a positioning track 220, and the length direction of the positioning track 220 is the same as the length direction of the sliding hole 121. At least two of the dynamic dust-proof arms 420 include a positioning arm 422, and the length direction of the positioning arm 422 is the same as the length direction of the sliding hole 121, and the positioning arm 422 and the positioning track 220 are slidably abutted.

[0068] In the above implementation, one of the two movable dust-proof arms 420 is a positioning arm 422. Through the mutual cooperation between the positioning arm 422 and the positioning track 220, the positioning of the latch assembly 30 can be achieved, thereby avoiding unnecessary movement of the latch assembly 30 after it moves to the appropriate position.

[0069] Exemplarily, the positioning track 220 has a plurality of positioning grooves 221, and the plurality of positioning grooves 221 are arranged at intervals in sequence along the length direction of the positioning track 220. The positioning arm 422 has a notch 423, and an elastic protrusion 424 is provided in the notch 423, and the elastic protrusion 424 is matched with the positioning groove 221.

[0070] During the movement of the latch assembly 30, the positioning arm 422 moves together therewith. During this process, the elastic protrusion 424 will enter and exit each positioning groove 221 in turn under the action of its own elasticity. After the latch assembly 30 finishes moving, the elastic protrusion 424 is clamped in the corresponding positioning groove 221 under the action of its own elasticity, thereby achieving positioning. Since a certain amount of force is required to overcome the elastic force of the elastic protrusion 424, the elastic protrusion 424 will not easily slide out after being clamped in the corresponding positioning groove 221, thereby achieving locking. When it is necessary to move the latch assembly 30, the operator applies a large external force to overcome the elastic force of the elastic protrusion 424, so that the elastic protrusion 424 can slide out of the positioning groove 221, and then unlocking is achieved.

[0071] Exemplarily, the elastic protrusion 424 includes an elastic arm 425 and a positioning protrusion 426. One end of the elastic arm 425 is connected to the positioning protrusion 426, and the other end of the elastic arm 425 is connected to the positioning arm 422.

[0072] In the above implementation, the elastic arm 425 functions to provide elastic force, so that the positioning protrusion 426 can enter and exit each positioning groove 221. The positioning protrusion 426 is matched with the positioning groove 221. After the latch assembly 30 stops moving, the positioning protrusion 426 can be clamped in the corresponding positioning groove 221, thereby achieving positioning.

[0073] Exemplarily, the elastic arm 425 is made of a material with certain elasticity. In this way, when one end degree of freedom of the elastic arm 425 is restricted, the other end can swing due to the elastic deformation of the elastic arm 425, thereby driving the positioning protrusion 426 to swing.

[0074] In some other embodiments, the elastic protrusion 424 includes two elastic arms 425. One ends of the two elastic arms 425 are respectively connected to the positioning protrusion 426, and the other ends of the two elastic arms 425 are respectively connected to the positioning arm 422.

[0075] In the above implementation, since the positioning protrusion 426 is respectively connected to the two elastic arms 425, its stability is better.

[0076] In this embodiment, one of the fixing pin 230 and the sleeve 122 is provided on the side of the partition 20 facing the second housing 120, and the other of the fixing pin 230 and the sleeve 122 is provided on the side of the second housing 120 facing the partition 20, and the fixing pin 230 is inserted into the sleeve 122.

[0077] In the above implementation, through the insertion fit between the fixing pin 230 and the sleeve 122, the connection between the partition 20 and the second housing 120 is realized, so that the protection component 40 can be firmly clamped by the partition 20 and the second housing 120, further improving the shielding effect of the protection component 40.

[0078] Exemplarily, the fixing pin 230 is connected to the partition 20, and the sleeve 122 is connected to the second housing 120. Of course, in other embodiments, the fixing pin 230 is connected to the second housing 120, and the sleeve 122 is connected to the partition 20. The present disclosure does not limit this.

[0079] An insert sleeve assembly 50 is further provided between the first housing 110 and the partition 20, and a jack corresponding to the insert sleeve assembly 50 is provided on the first housing 110.

[0080] Wherein, the insert sleeve assembly 50 includes an L-pole insert sleeve, an N-pole insert sleeve, and an E-pole insert sleeve, and the plug assembly 30 includes an L-pole plug, an N-pole plug, and an E-pole plug. The L-pole insert sleeve is electrically connected to the L-pole plug, the N-pole insert sleeve is electrically connected to the N-pole plug, and the E-pole insert sleeve is electrically connected to the E-pole plug.

[0081] Exemplarily, between the L-pole insert sleeve and the L-pole plug, between the N-pole insert sleeve and the N-pole plug, and between the E-pole insert sleeve and the E-pole plug, they are respectively electrically connected by three different wires. The wires can swing flexibly along with the relative movement between the plug assembly 30 and the insert sleeve assembly 50, thus effectively avoiding problems such as fracture and poor contact at the welding joints between the wires and the insert sleeve assembly 50 and the plug assembly 30 due to swinging, and thus causing problems such as temperature rise and overheating.

[0082] Exemplarily, the wire is a flexible wire body, which can generate a certain deformation on the basis of ensuring its own electrical performance, so as to adapt to the relative movement between the plug assembly 30 and the insert sleeve assembly 50.

[0083] See Figure 3, in this embodiment, the soldering positions of the copper wire core 100 of the wire with the L-pole pin, N-pole pin, and E-pole pin are located at the position between the two moving dust-proof arms 420, and the insulating outer sheath 200 of the wire is clamped in the groove or clamping opening 427 of the moving dust-proof arm 420. When the pin assembly 30 slides, the swinging part of the wire is the insulating outer sheath 200 clamped on the moving dust-proof arm. Therefore, the copper wire core 100 at the soldering position does not swing, ensuring the reliability of the soldering position and not being affected by the sliding of the pin assembly 30.

[0084] Exemplarily, one moving dust-proof arm 420 has a clamping opening 427 for clamping the wire corresponding to the E-pole pin. The other moving dust-proof arm 420 has two clamping openings 427, one of the two clamping openings 427 for clamping the wire corresponding to the L-pole pin, and the other of the two clamping openings 427 for clamping the wire corresponding to the N-pole pin.

[0085] In the above implementation, the wire corresponding to the E-pole pin can be independent of the wires corresponding to the L-pole pin and the N-pole pin, thereby further improving the electrical safety of the converter.

[0086] In some implementations, the clamping opening 427 is a U-shaped groove that can accommodate the wire. In other implementations, the clamping opening 427 is a U-shaped groove with an inwardly tapered opening, which can not only accommodate the wire but also help to keep the wire in the clamping opening 427, avoiding unnecessary movement of the wire and improving the reliability of the converter.

[0087] Exemplarily, the side of the pin assembly 30 facing the partition 20 has three wire grooves 310, which are recessed in the side of the pin assembly 30 facing the partition 20. The three wire grooves 310 are the L-pole wire groove, N-pole wire groove, and E-pole wire groove respectively, for accommodating three wires. The wire is soldered to the L-pole pin in the L-pole wire groove, the wire is soldered to the N-pole pin in the N-pole wire groove, and the wire is soldered to the E-pole pin in the E-pole wire groove.

[0088] In the above implementation, through the design of the wire grooves 310, the thickness dimension of the pin assembly 30 can be effectively utilized, thereby reducing the thickness dimension of the converter, which is conducive to the thin and light design of the converter.
