Description

Technical Field

[0001] The utility model relates to the field of housings of electronic / electrical equipment, in particular to a housing with an anti-slip wire structure. Background Art

[0002] refer to Figure 1A , a wire crimping structure of an existing device is illustrated, specifically, the device has a wiring terminal 1P, a wire crimping seat 2P arranged at the front end of the wiring terminal 1P, and a wire crimping device 3P matched with the wire crimping seat 2P, wherein the wire crimping seat 2P has a wire crimping portion 21P and two screw mounting columns 22P arranged at both ends of the wire crimping portion 21P, wherein the wire crimping device 3P is fixed to the wire crimping portion 21P by a locking screw 4P. The existing wire crimping device 3P is fixed by the screw 4P, which makes the wire crimping operation extremely complicated. The operator must apply force to the wire crimping device 3P in the process of locking the screw 4P to prevent the wire from detaching, and must accurately lock the screw 4P, which must be completed by at least two hands. During operation, the operator also needs to use additional operating tools, such as a screwdriver to lock the screw 4P in the screw mounting column 22P, and the operation is cumbersome and complicated. During disassembly, the operator also needs tools to complete the installation and disassembly of the wire pressing device 3P. Without special tools, the installation and disassembly of the wire pressing device 3P cannot be completed, which is time-consuming and laborious, and very inconvenient. In terms of operating habits, the operator is accustomed to tightening the screw 4P, but when the cable is too thick, the screw 4P will not be able to be screwed to the bottom. The operator's brute force operation will cause the screw 4P and / or the screw installation column 22P to be damaged, which is easy to cause the screw 4P to be wired, resulting in the screw 4P cannot be reused, which is very likely to cause resource waste.

[0003] At present, the cost of using sensors, power supplies, etc. is more about the labor cost of electricians than the price cost of the equipment itself. Especially for the European market, electricians have a specific threshold as a professional job. Electrical equipment needs to be completed by professional electricians from procurement to installation, and the cost of electricians is charged on an hourly basis. As mentioned above, the wire crimping of existing equipment is very complicated, which means that electricians need to spend a lot of time to perform the wire crimping operation, making it difficult to shorten the installation time of the equipment, making it difficult to reduce labor costs, and ultimately resulting in high cost of using the corresponding equipment.

[0004] In view of this, how to quickly press the wire has become the goal pursued by the industry. Figure 1BAs shown, the utility model patent with announcement number CN209341194U discloses a power box, which includes a wire crimping bottom cover 121, a wire crimping plate 122 and a wire crimping upper cover 123 which are snap-connected to the wire crimping bottom cover 121 in sequence, the wire crimping plate 122 and the wire crimping upper cover 123 are snap-connected to the wire crimping bottom cover 121 in sequence, the wire crimping bottom cover 121 is provided with a positioning block 1210 and a snap-connecting block 126, the wire crimping plate 122 is provided with a snap-connecting hole which matches the size of the snap-connecting block 126, the wire crimping bottom cover 121 and the wire crimping plate 122 are snap-connected to the snap-connecting hole through the snap-connecting block 126, so that the wire crimping is performed by snap-connecting, which improves the convenience of wire crimping compared to the wire crimping structure installed with screws.

[0005] However, the wire pressing plate 122 is a component that exists independently of the power box and is small in size. During transportation and operation, it is very likely that the wire pressing plate 122 will be lost because it is separated from the wire pressing bottom cover 121, resulting in the loss of accessories. Figure 1C As shown, the utility model patent with announcement number CN215073340U discloses a power drive box, and a first area 11 for storing a wire buckle 21 is provided on the shell of the power drive box, which can reduce the probability of accessories being lost during transportation due to the independent packaging of the wire buckle 21 and the shell to a certain extent. However, during the installation operation, the wire buckle 21 needs to be taken out from the shell first, and then placed in the corresponding wire buckle structure for wire pressing, which is inconvenient to operate, especially when the operator climbs up to operate, the wire buckle 21 is small in size, and when the operator applies force to take the wire buckle 21 out of the shell, it is also easy to cause the wire buckle 21 to fall or even lose. As an accessory for special applications, the manufacturer rarely configures redundant accessories when shipping, and in most cases, such accessories will not be sold separately, which leads to the loss of accessories. In serious cases, the equipment cannot be used anymore, resulting in an increase in the user's equipment expenditure cost. And even if suitable accessories can be found for supplementation, the working time required by professionals in the adaptation of accessories will also increase the user's labor cost.

[0068] Referring to the drawings of the specification of the utility model Figures 2 to 6 A shell 100 with an anti-slip wire-pressing structure according to an embodiment of the utility model is illustrated, wherein the shell 100 with an anti-slip wire-pressing structure includes a shell body 10, a wire-pressing seat 20 and a wire-pressing buckle 30, wherein the wire-pressing seat 20 is arranged on the shell body 10, wherein the wire-pressing seat 20 and the wire-pressing buckle 30 have matching structures, so that when the wire-pressing buckle 30 is inserted into the wire-pressing seat 20, the corresponding cable is clamped up and down between the wire-pressing buckle 30 and the wire-pressing seat 20, wherein the wire-pressing buckle 30 is anti-slip installed on the wire-pressing seat 20, thereby avoiding the risk of loss of the wire-pressing buckle 30 due to separation from the wire-pressing seat 20, effectively preventing the loss of accessories and avoiding additional costs.

[0069] In detail, the wire pressing seat 20 includes a wire pressing threshold 21 and two limit slot columns 22 erected at both ends of the wire pressing threshold 21, wherein the limit slot column 22 includes a multi-step limit wall 221 and two guide limit walls 222 erected on both sides of the multi-step limit wall 221, wherein the two guide limit walls 222 of one of the limit slot columns 22 of the wire pressing seat 20 are provided with a sliding groove 223 along the insertion direction of the wire pressing buckle 30, wherein the wire pressing buckle 30 has a sliding groove 223 with the sliding groove 221. 23 matches the rotating shaft 351, wherein the wire pressing buckle 30 is flipably installed on the wire pressing seat 20 in a state where the rotating shaft 351 is inserted into the sliding groove 223, wherein the rotating shaft 351 can slide along the sliding groove 223, and when the rotating shaft 351 slides to the top of the sliding groove 223, the sliding groove 223 forms a limit for the rotating shaft 351 in the insertion direction, and the wire pressing buckle 50 can be flipped relative to the wire pressing seat 30 with the rotating shaft 351 as the axis.

[0070] Furthermore, the wire pressing buckle 30 includes a pressing plate 31, an insertion arm 32 extending from both sides of the pressing plate 31, an insertion guide column 33 extending downward from the end of the pressing plate 31, and a wire pressing plate 34 arranged between the two insertion arms 32, wherein when the wire pressing buckle 30 is inserted into the wire pressing seat 20, the two insertion arms 32 and each insertion guide column 33 are limited between the two limiting groove columns 22, wherein the limiting groove column 22 having the sliding groove 223 is defined as an anti-slip limiting groove column 22, and the wire pressing buckle 30 corresponds to the anti-slip limiting groove column One side of 22 is the flip connection side of the wire buckle 30, wherein the two insertion guide columns 33 of the wire buckle 30 located on the flip connection side extend from one end away from the pressing plate 31 to have a flip connection part 35, wherein the rotating shaft 351 extends backwards from the two flip connection parts 35, wherein the wire buckle 30 is flipably installed on the wire pressing seat 30 in a state where the rotating shaft 351 is inserted into the sliding groove 223, so as to prevent the wire buckle 30 from being separated from the wire pressing seat 20 based on the limitation of the rotating shaft 351 in the insertion direction formed by the sliding groove 223.

[0071] It is worth mentioning that when the wire crimping buckle 30 is inserted downward into the wire crimping seat 20 from the upper end of the wire crimping seat, the two insertion arms 32 and the insertion guide columns 33 are limited between the two limiting groove columns 22. In this way, when performing the corresponding wire crimping operation, the insertion arm 32 and the insertion guide column 33 can be driven to insert into the corresponding limiting groove column 22 by pressing the pressing plate 31 with one hand, so that the wire crimping buckle 30 can be inserted into the wire crimping seat 20 with one hand and the corresponding wire crimping operation can be completed with one hand.

[0072] When releasing the wire pressing, the two insertion arms 32 are pinched with one hand to reduce the lateral dimension of the wire pressing buckle 30 formed between the two insertion arms 32, thereby canceling the limitation of the two multi-step limiting walls 221 on the two insertion arms 32, so that the wire pressing buckle 30 can be moved upward. At this time, the rotating shaft 351 slides along the sliding groove 223 and is limited at the upper end of the sliding groove 223, thereby preventing the wire pressing buckle 30 from being separated from the wire pressing seat 20, wherein the wire pressing buckle 30 is pivotally mounted on the anti-slip limiting groove column 22 and can pivot with the rotating shaft 351 as the axis in the direction away from the other limiting groove column 22, so as to prevent the wire pressing buckle 30 from slipping off and facilitate the operator to install the corresponding cable. In this way, the wire pressing efficiency is improved while facilitating the one-handed wire pressing operation, and the loss of accessories is prevented. While improving the wire pressing efficiency and shortening the installation time, it also effectively avoids the extra working time caused by the loss of accessories, effectively reducing the installation labor cost of the corresponding equipment.

[0073] In particular, the wire crimping buckle 30 is installed on the wire crimping seat 20 to prevent it from falling off. When the operator performs corresponding wiring and crimping operations, the wire crimping buckle 30 is connected to the wire crimping seat 20 without looking for accessories. After the wiring is completed, by flipping the wire crimping buckle 30 and applying force to the pressing plate 31 to insert the wire crimping buckle 30 from top to bottom into the wire crimping seat 20, on the one hand, a force is applied to prevent the cable from detaching from the wire crimping seat 20, and on the other hand, the insertion of the wire crimping buckle 30 and the wire crimping seat 20 is completed, and the wire crimping operation is realized in one step, thereby simplifying the process steps during the wire crimping operation, thereby effectively shortening the installation time of the corresponding equipment and reducing labor costs.

[0074] It is worth mentioning that the insertion direction of the wire pressing buckle 30 is the height direction of the shell 100 with the anti-detachment wire pressing structure, and the height of the two guide limiting walls 222 of the anti-detachment limiting groove column 22 is higher than the height of the two guide limiting walls 222 of the other limiting groove column 22. Therefore, when the wire pressing buckle 30 is flipped over, it can be ensured that the wire pressing buckle 30 is disengaged from the other limiting groove column 22, which is conducive to the wire pressing buckle 30 being disengaged from the other limiting groove column 22 and flipping over, thereby ensuring the smooth flipping of the wire pressing buckle 30.

[0075] Furthermore, the insertion arm 32 includes a fixed plate 321, an elastic plate 322 extending from the fixed plate 321, and a pinching force-applying portion 323 extending from the elastic plate 322, wherein the fixed plate 321 extends downward from the side end of the pressing plate 31 and has a lower end away from the pressing plate 31, and the elastic plate 322 extends upward and outward from the lower end to generate a variable gap between the fixed plate 321, wherein the elastic plate 322 has an end away from the fixed plate 321, and the pinching force-applying portion 323 extends outward from the end and has a widened size relative to the elastic plate 322, so that the operator can pinch the pinching force-applying portion 323 to apply force to the insertion arm 32.

[0076] In particular, the two side ends extending from the insertion arm 32 are the wide side ends 311 of the pressing plate 31, and the pressing plate 31 has a long side end 312 connecting the two wide side ends 311, wherein the two wide side ends 311 of the pressing plate 31 are concave inward relative to the end of the pressing plate 31, so as to form a pinching avoidance position 3110 between the end of the pressing plate 31 in the width direction of the pressing plate 31, so as to facilitate the operator to apply inward force to the elastic plate 322, thereby releasing the limitation of the elastic plate 322 by the multi-step limiting wall 221.

[0077] Furthermore, the facing sides of the two multi-step limiting walls 221 of the wire crimping seat 20 are the inner side surfaces 2211 of the multi-step limiting walls 221, wherein the multi-step limiting walls 221 are provided with multi-step clamping positions 51 on the inner side surfaces 2211, wherein the elastic plate 322 is provided with at least one buckle 52 on the side facing away from the fixed plate 321, so that when the wire crimping buckle 30 is inserted into the wire crimping seat 20, the buckle 52 engages with the multi-step clamping position 51, thereby forming upper and lower limits for the wire crimping buckle 30, and based on the different height positions of the buckle 52 engaged with the multi-step clamping position 51, it is beneficial to improve the adaptability to cables of different sizes.

[0078] It is worth mentioning that the height of the multi-step limiting wall 221 is lower than the height of the guide limiting wall 222 and a top avoidance opening 2201 is formed above the multi-step limiting wall 221, so that when the wire pressing buckle 30 is inserted into the wire pressing seat 20, the pinching force applying part 323 extends outward from the top avoidance opening 2201 to the limiting slot column 22, so that the operator can apply force to the pinching force applying part 323.

[0079] In particular, the multi-step latching position 51 is arranged in a state biased toward the top avoidance opening 2201 to keep the buckle 51 engaged with the multi-step latching position 51 at a position biased toward the end, thereby ensuring that the engagement between the multi-step latching position 51 and the buckle 52 can be smoothly released during disengagement, thereby facilitating the disengagement operation of the wire buckle 30.

[0080] In particular, the top avoidance opening 2201 and the anti-slip limit slot column 22 also form a flipping avoidance for the wire pressing buckle 30, which is beneficial to ensure the flipping angle of the wire pressing buckle 30 and avoid the wire pressing buckle 30 from causing obstruction to the wiring operation.

[0081] Furthermore, for the purpose of increasing the flipping angle of the wire buckle 30, the two side edges of the multi-step limiting wall 221 of the anti-slip limiting slot column 22 are preferably designed to be sunken and to form a flipping avoidance groove 2202 between the multi-step limiting wall 221 and the guide limiting wall 222, wherein when the wire buckle 20 pivots in the direction away from the other limiting slot column 22, the flip connection part 35 of the wire buckle 20 can be embedded in the flipping avoidance groove 2202 to expand the flipping angle of the wire buckle 20, effectively avoiding the wire buckle 20 from causing obstruction to the corresponding wiring operation, thereby avoiding the loss of accessories and ensuring the wiring efficiency.

[0082] In particular, the crimping seat 20 is provided with an outward-turned clamping structure, wherein the outward-turned clamping structure is used to clamp the crimping buckle 30 when the crimping buckle 30 is turned outward to a corresponding angle relative to the crimping seat 20, so that the positions of the crimping buckle 30 and the crimping seat 20 remain relatively fixed.

[0083] It is worth mentioning that the anti-slip limit groove column 22 can also form a clamp on the flip connection part 35 to constitute the outward clamping structure, so that when the wire buckle 30 is flipped away from the other limit groove column 22, for example, when the flip angle of the wire buckle 30 exceeds 90°, it is gradually clamped by the anti-slip limit groove column 22 to prevent the wire buckle 30 from shaking and returning to its original position and flipping, thereby effectively preventing the wire buckle 30 from causing obstruction to the corresponding wiring operation.

[0084] Specifically, the facing sides of the two guide limiting walls 222 of the anti-slip limiting groove column 22 are named as limiting surfaces 2220, and the sliding groove 223 extends inwardly from the limiting surface 2220, wherein the sliding groove 223 divides the limiting surface 2220 into a first surface 2221 and a second surface 2222 along the insertion direction of the wire buckle 30, wherein compared with the second surface 2222, the first surface 2221 is closer to the other limiting groove column 22, wherein the distance between the two second surfaces 2222 is smaller than the distance between the two first surfaces 2221, so that when the wire buckle 30 pivots in the direction away from the other limiting groove column 22, the flip connection part 35 of the wire buckle 30 slides along the first surface 2221 to the second surface 2222, and is gradually clamped by the limiting surface 2220, thereby preventing the wire buckle 30 from shaking and effectively avoiding the wire buckle 30 from causing obstruction to the corresponding wiring operation.

[0085] In particular, an arc surface or a bevel transition is adopted between the first surface 2221 and the second surface 2222 to improve the flipping feel of the wire buckle 30 and make the wire buckle 30 pivot more smoothly in the direction away from the other limiting slot column 22.

[0086] Furthermore, in order to strengthen the structure of the wire pressing buckle 30 and ensure the accuracy during the wire pressing process, so as to ensure the firmness of the wire pressing, the wire pressing buckle 30 is further provided with a reinforcing edge 361 protruding and extending from the two long side ends 312 of the pressing plate 31 in the width direction and a reinforcing column 362 extending downward from both ends of the reinforcing edge 361, wherein the reinforcing column 362 and the insertion guide column 33 form an insertion guide groove 331, wherein when the wire pressing buckle 30 is inserted into the wire pressing seat 20, the guide limiting wall 222 is respectively in contact with the insertion guide column 33 and the reinforcing column 362 in the insertion guide groove 331, thereby forming a limit to the wire pressing buckle 30 and a guide during the insertion process, thereby ensuring the firmness of the wire pressing of the wire pressing buckle 30 and the wire pressing seat 20.

[0087] Furthermore, the wire buckle 30 also includes a reinforcing plate 363 extending downward from the long side end 312 of the pressing plate 31 and connected to the plug-in guide column 33, so as to strengthen the structure of the wire buckle 30 and enhance the structural integrity of the wire buckle 30 based on the connection of the reinforcing plate 363 to the two plug-in guide columns 33 located on its two side edges, thereby improving the structural stability of the wire buckle 30.

[0088] Furthermore, the wire pressing plate 34 extends downward from the pressing plate 31 and is connected to the two fixing plates 321 of the insertion arm 32, thereby helping to strengthen the structure of the wire pressing buckle 30 and enhance the structural integrity of the wire pressing buckle 30, thereby improving the structural stability of the wire pressing buckle 30.

[0089] In particular, in this embodiment of the utility model, the number of the wire-pressing thresholds 21 is two, and the ends of the two wire-pressing thresholds 21 respectively correspond to the two guide limiting walls 222 of the limiting slot column 22, wherein when the wire-pressing buckle 30 is inserted into the wire-pressing seat 20, the wire-pressing plate 34 is located between the two wire-pressing thresholds 21 to ensure the firmness of the wire-pressing of the cable.

[0090] It is worth mentioning that in order to ensure the adaptability to cables of different wire diameters, the shell 100 with an anti-slip wire pressing structure further includes an adapter 40, wherein the adapter 40 includes a clamping groove 41 and an extended wire pressing plate 42 extending from the bottom of the clamping groove 41, wherein the adapter 40 is suitable for being detachably installed on the wire pressing buckle 30 in a state where the wire pressing plate 34 is embedded in the clamping groove 41, so as to reduce the wire pressing height of the wire pressing buckle 30 based on the extension design of the extended wire pressing plate 42 at the bottom of the clamping groove 41, thereby improving the adaptability to cables with small diameters.

[0091] Further reference to the drawings of the specification of the present utility model Figures 7 to 9, an optimized structure of the shell 100 with the anti-slip pressure wire structure is illustrated. On the basis of the structure of the shell 100 with the anti-slip pressure wire structure mentioned above, the multi-step limiting wall 221 of the shell 100 with the anti-slip pressure wire structure is further optimized, so that the flip avoidance groove 2202 can gradually clamp the pressure wire buckle 30 when the pressure wire buckle 30 is flipped, thereby further constituting a part of the outward-turning clamping structure. Specifically, the multi-step limiting wall 221 of the anti-slip limiting groove column 22 has a side edge surface 2212 facing the second surface 2222, wherein the flip avoidance groove 2202 is opened between the side edge surface 2212 and the second surface 2222, wherein the side edge surface 2212 approaches the second surface 2222 from the first surface 2221 to the second surface 2222, and the side edge surface 2212 is designed in the form of an inclined surface or an arc surface and approaches The second surface 2222 is so that the flip avoidance groove 2202 has a groove width that decreases along the direction from the first surface 2221 to the second surface 2222, wherein the second surface 2222 can also be designed in the form of a slope or an arc surface to cooperate with the side surface 2212, so that the groove width of the flip avoidance groove 2202 in the direction from the first surface 2221 to the second surface 2222 gradually decreases, so that when the wire buckle 30 pivots in the direction away from the other limiting slot column 22, the flip connection part 35 is gradually clamped by the flip avoidance groove 2202, that is, when the flip angle of the wire buckle 30 is larger, the flip avoidance groove 2202 clamps the wire buckle 30 more firmly, which is beneficial to prevent the wire buckle 30 from shaking, and is beneficial to keep the wire buckle 30 in the open state without automatically returning to its position, effectively avoiding the wire buckle 30 from causing obstruction to the corresponding wiring operation.

[0092] In particular, the side surface 2212 can adopt a bevel or arc transition design to gradually approach the second surface 2222, so that the flip avoidance groove 2202 has a groove width that gradually decreases along the direction from the first surface 2221 to the second surface 2222. The side surface 2212 can also adopt a step-shaped transition design to approach the second surface 2222, so that the flip avoidance groove 2202 has a groove width that gradually decreases along the direction from the first surface 2221 to the second surface 2222.

[0093] Furthermore, the length direction of the wire pressing threshold 21 is the lateral direction of the shell 100 with the anti-slip wire pressing structure, wherein the shell body 10 has two side edges 11 in the lateral direction, wherein the wire pressing buckle 30 is arranged to flip toward one of the side edges 11 of the shell body 10, wherein the position of the side edge 11 in the flipping direction of the wire pressing buckle 30 is designed to be sunken and has a sinking avoidance groove 1101 to expand the flipping angle of the wire pressing buckle 30, effectively avoiding the wire pressing buckle 30 from causing obstruction to the corresponding wiring operation, thereby ensuring the wiring efficiency while avoiding the loss of accessories.

[0094] In particular, the flip connection portion 35 is widened relative to the plug-in guide column 33 and forms a concave arc transition edge 3501 with the plug-in guide column 33, so that when the wire buckle 30 is flipped, the concave arc transition edge 3501 corresponds to the bottom of the flip avoidance groove 2202, so that the flip angle of the wire buckle 30 is expanded, which effectively avoids the wire buckle 30 from causing obstruction to the corresponding wiring operation, thereby avoiding the loss of accessories and ensuring the wiring efficiency.

[0095] Further reference to the drawings of the specification of the present utility model Fig.10 An optional structure of the shell 100 with the anti-slip wire pressure structure is illustrated. In this structure, the flip avoidance groove 2202 is not set, and the height difference between the multi-step limiting wall 221 and the guide limiting wall 222 of the anti-slip limiting groove column 22 is set to ensure the flipping angle of the wire buckle 30, which is beneficial to simplify the structure of the shell 100 with the anti-slip wire pressure structure.

[0096] In particular, referring to the drawings of the specification of the present utility model Figure 2 and Figure 3 In this embodiment of the utility model, the housing body 10 further includes a terminal flip cover 12, wherein the terminal flip cover 12 is flipably disposed on the housing body 10 and is suitable for shielding the corresponding wiring terminals, the crimping seat 20 and the crimping buckle 30 in a closed state, thereby ensuring the surface cleanliness of the housing body 10 and protecting the wiring terminals, the crimping seat 20 and the crimping buckle 30. The housing body 10 can be designed to be transparent or semi-transparent, and the semi-transparent design, for example, the terminal flip cover 12 is made transparent to facilitate the operator to observe the corresponding wiring crimping situation, which is not limited by the utility model.

[0097] It is worth mentioning that the shell body 10 defines a accommodating cavity, in which the components / functional units of the corresponding equipment can be accommodated, such as but not limited to PIR sensors, ultrasonic sensors, microwave sensors, infrared sensors, TOF sensors, power supplies, controllers, lamps, etc., and the cables connected to the corresponding equipment can be crimped and fixed based on the shell 100 with an anti-slip crimping structure, thereby shortening the installation time of the corresponding equipment and reducing the labor cost of installing the corresponding equipment.
