Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] The snap-fit ​​assembly provided in this embodiment of the utility model, such as Figure 2 As shown, it includes: a base 16 and a fastener 11. The base 16 has three snap-fit ​​positions, and the fastener 11 is slidably mounted on the base 16 and can slide to the three snap-fit ​​positions to present three different snap-fit ​​postures.

[0037] This embodiment sets up three snap-fit ​​stations that cooperate with the snap-fit ​​component 11. Each snap-fit ​​station corresponds to a snap-fit ​​posture, thereby meeting three different assembly or installation requirements. The snap-fit ​​component has a simple structure, good versatility, and can meet various installation requirements of electrical equipment.

[0038] In this plan, such as Figure 4 As shown, the three snap-fit ​​stations include a first snap-fit ​​slot 12, a second snap-fit ​​slot 13, and a third snap-fit ​​slot 14. The snap-fit ​​component 11 includes a snap-fit ​​tongue 112, which can slide to engage with the first snap-fit ​​slot 12, the second snap-fit ​​slot 13, and the third snap-fit ​​slot 14 respectively to form a first snap-fit ​​posture, a second snap-fit ​​posture, and a third snap-fit ​​posture.

[0039] like Figure 2 and Figure 5 As shown, the fastener 11 is provided with a mounting hole 111 for screw assembly; the base 16 is provided with a sliding groove 15, through which the fastener 11 can be slidably mounted on the base 16, and the sliding groove 15 facilitates the sliding of the fastener 11.

[0040] Furthermore, the fastener 11 is provided with a limiting part for cooperating with the slide groove 15, the limiting part being used to limit the sliding stroke of the fastener 11; and / or, the fastener 11 is provided with a sliding part, the sliding part being used to guide the fastener 11 into the slide groove 15; and / or, the fastener 11 is provided with a viewing window 113, the viewing window 113 being used to observe the fastening posture of the fastener 11, thereby facilitating observation of which slot the fastener's latch is located in.

[0041] Specifically, the snap-fit ​​assembly in this embodiment can be used with a DIN rail, specifically a DIN rail with a width of 35mm. The DIN rail is a German industrial standard, and using rails is a common installation method for industrial electrical components. Electrical components that support this standard can be easily snapped onto the rail without the need for screws, and maintenance is also very convenient.

[0042] In one embodiment, when the latch 112 engages with the first slot 12 to form a first latching posture, the latching component is completely stored on the base, which can effectively solve the problem in the prior art where the latching component is randomly placed when not in use and cannot be found when needed; when the latch 112 engages with the second slot 13 to form a second latching posture, the engaging part 117 of the latching component 11 cooperates with other engaging parts on the electrical equipment, so that the electrical equipment is latched on the longitudinal (i.e., perpendicular to the sliding direction of the latching component) din guide rail, completing the second latching posture, that is, completing the latching function; when the latch 112 engages with the third slot 14 to form a third latching posture, the mounting hole 111 on the latching component 11 protrudes from the housing of the electrical equipment, so that the screw can be assembled through the mounting hole 111, and can be installed on the wall to be installed.

[0043] This embodiment sets up three slots that cooperate with the latch 112, each slot corresponding to a different latching posture, thereby satisfying three installation requirements: storage, snap-fit, and screw installation. This can meet most of the installation requirements of electrical equipment and can handle various complex installation needs. The latching assembly has a simple structure, good versatility, improves product compatibility and consistency, and can reduce product assembly costs.

[0044] It should be noted that, in the embodiments described above, the snap-fit ​​components are all in one set; however, in this embodiment, there are two sets of snap-fit ​​components. Correspondingly, the number of snap-fit ​​parts 11 can be two, and the number of bases 16 can be two or one, i.e., the base and the housing are designed as an integral unit; the three snap-fit ​​stations can be a first snap-fit ​​station, a second snap-fit ​​station, and a third snap-fit ​​station. The snap-fit ​​part 11 can include a snap-fit ​​body and a snap-fit ​​tongue 112 disposed on the snap-fit ​​body; correspondingly, the first snap-fit ​​station can include two first snap-fit ​​slots 12, the second snap-fit ​​station can include two second snap-fit ​​slots 13, and the third snap-fit ​​station can include two third snap-fit ​​slots 14.

[0045] Among them, such as Figure 4As shown, two first slots 12 can be opened opposite each other on both sides of the base 16 along a first direction, two second slots 13 can be opened opposite each other on both sides of the base 16 along a first direction, and the two first slots 12 can be located between the two second slots 13, and two third slots 14 can be opened opposite each other on both sides of the base 16 along a first direction, and the two second slots 13 can be located between the two third slots 14; wherein, the first direction is the relative direction of the two fasteners 11, that is, the direction of the line connecting the two fasteners 11, which is denoted as the horizontal direction.

[0046] like Figure 1 As shown, the latches 112 of the two latching parts 11 can slide towards each other until they engage with the two first latching slots 12 one by one to form a first latching posture. At this time, the latching gap between the two latching parts 11 is less than the width of the guide rail 3, and the guide rail 3 cannot be latched. At this time, the latching parts are completely stored on the base, which can effectively solve the problem in the prior art that the latching parts are randomly placed when not in use and cannot be found when needed; for example Figure 7 As shown, instead of being mounted, the guide rail 3, i.e., the horizontal guide rail, is secured in the first position by the second snap-fit ​​assembly on the back of the electrical equipment housing; of course, at this time, the relative direction of the two snap-fit ​​pieces 11 is parallel to the guide rail 3 in the first position.

[0047] like Figure 3 As shown, the latches 112 of the two latching parts 11 can also slide back to back until they engage with the two second latching slots 13 one by one to form a second latching posture, as shown. Figure 8 As shown, at this time, the clamping gap between the two latching parts 11 is adapted to the width of the guide rail 3, which can clamp the guide rail 3 in the second posture, i.e., the longitudinal guide rail; thus completing the latching function of the latching assembly.

[0048] like Figure 5 As shown, the latches 112 of the two latching pieces 11 can also slide back to back until they engage with the two third latching slots 14 one by one to form a third latching posture. At this time, the first part of the two latching pieces 11 protrudes out of the base 16, and the electrical equipment housing can be directly installed on the wall or cabinet to be installed through the installation structure of the first part of the two latching pieces 11.

[0049] In other words, the fastener 11 is provided with a latch 112, and each snap-fit ​​station of the base 16 includes a slot. That is, the fastener 11 is snapped into different snap-fit ​​stations by the latch 112 engaging with the slot. This snap-fit ​​method is simple in structure and convenient to snap-fit. Of course, after the latch 112 is engaged with the slot, the latch 112 can be released by moving the latch 112.

[0050] Specifically, such as Figure 5As shown, the fastener 11 has mounting holes 111 for screw assembly. As mentioned above, when the two fasteners 11 slide back-to-back to the third engagement position, their first parts protrude beyond the base 16. The mounting structure of the first part of the two fasteners 11 is the mounting hole 111. That is, when the two fasteners 11 are at the third engagement position, the parts protruding beyond the base 16 both have mounting holes 111. Then, two screws are used to install the two mounting holes 111 of the fastener assembly into the cabinet of the electrical equipment. This allows the back of the electrical equipment housing to be directly screwed into the cabinet without the need for the guide rail 3, making the electrical equipment easier to install in the cabinet. Of course, the back of the electrical equipment housing can also be directly screwed into the cabinet horizontally or vertically.

[0051] Furthermore, such as Figure 2 As shown, the base 16 is provided with a sliding groove 15, through which the fastener 11 is slidably mounted on the base 16. As mentioned above, the number of fasteners 11 can be two. Correspondingly, the base 16 is provided with two sliding grooves 15, allowing the two fasteners 11 to be slidably mounted on the base 16 one through each of the two sliding grooves 15. In other words, the two fasteners 11 can be relatively slidably mounted on the base 16 through the two sliding grooves 15, ensuring stable and reliable sliding of the two fasteners 11 on the base 16. Furthermore, the sliding groove 15 may include a first sliding groove and a second sliding groove arranged in parallel, i.e., the sliding groove 15 has a double sliding groove structure, the structure of which can be referred to... Figure 2 As shown, the two sides of the fastener 11 can slide along the first and second slide grooves respectively.

[0052] It should be noted that, as mentioned above, the buckle 11 includes a buckle body, and the slide 15 has a double slide structure, which means it can include a first slide and a second slide arranged in parallel; wherein, the first slide and the second slide can both be L-shaped strip slides, and the two strip slides are inverted and arranged in parallel on the base 16, as shown. Figure 2 As shown, the buckle body is provided with two limiting end faces 114, which are used to abut against the sliding end faces (end faces near the edge of the base 16) of the two strip slide rails to limit the maximum sliding stroke of the buckle 11 along the slide groove 15, that is, to limit the maximum sliding amount of the buckle 11 into the slide groove 15, so that when the two buckles 11 slide to the first snap-fit ​​position, the snap-fit ​​gap between them is the preset snap-fit ​​gap, and at the same time ensure that the two buckles 11 can slide towards each other to the first snap-fit ​​position; of course, the two limiting end faces 114 of the buckle 11 serve as the limiting part of the buckle 11 mentioned above.

[0053] The fastener 11 is provided with a sliding part for guiding the fastener 11 into the slide groove 15; wherein, for example Figure 2As shown, the sliding part can be a sliding part 115 opened on both sides of the buckle 11, and the sliding part 115 can be a vertical sliding part, which is matched with an L-shaped strip rail. Correspondingly, the end face of the strip rail used to cooperate with the vertical sliding part on one side of the buckle 11 is also a vertical end face. Of course, the sliding part of the buckle 11 is designed in this way, which makes the structure simple and the guidance convenient.

[0054] like Figure 2 As shown, the fastener 11 is also provided with a viewing window 113, which is used to observe the fastening posture of the fastener 11, that is, to observe the engagement of the latch 112 of the fastener 11 with the corresponding slot; wherein, the viewing window 113 can be a through slot, and can penetrate the top and bottom of the fastener body, which makes it easier to observe the engagement of the latch 112 of the fastener 11 with the corresponding slot; of course, if Figure 4 As shown, the latch 112 of the fastener 11 can be disposed within the visible slot; furthermore, as Figure 2 As shown, the fastener 11 may also be provided with several through-type light-reducing grooves 116.

[0055] It should be noted that, as Figure 1 As shown, the above-mentioned latching component can be a first latching component 1, which can be disposed on the back of the electrical equipment housing, and can be staggered (for example, orthogonally distributed) with the original second latching component 2 on the back of the electrical equipment housing. Specifically, the first latching component 1 is located on the left and right sides of the electrical equipment housing, and the second latching component 2 is located on the upper and lower sides of the electrical equipment housing.

[0056] Among them, such as Figure 7 As shown, the latching gap of the second latching component 2 can be adapted to the width of the guide rail 3 in the first posture (such as the X-direction posture), and can be used to latch the guide rail 3 in the first posture so that the back of the electrical equipment housing is fixed to the guide rail 3 in the first posture, and the electrical equipment can be installed in the cabinet in the first posture (such as the X-direction posture) through the guide rail 3.

[0057] like Figure 2 As shown, the snap fastener 11 is the first snap fastener, and there can be two of them. That is, the two snap fasteners 11 can be slidably disposed on the base 16, and can slide towards or away from each other to the first snap-fit ​​position, so as to assume the first snap-fit ​​posture (e.g., Figure 1 As shown), in this posture, the gap between the two latching parts 11 is smaller than the width of the guide rail 3, so the guide rail 3 cannot be latched. Therefore, in this posture, the guide rail 3 in the first posture can be latched onto the second latching assembly 2.

[0058] The two snap fasteners 11 can also slide towards or away from each other to the second snap-fit ​​position, so as to assume a second snap-fit ​​posture (e.g. Figure 3As shown), in this posture, the clamping gap between the two latching pieces 11 can be adapted to the width of the guide rail 3 in the second posture (such as the Y-direction posture), thus it can be used to clamp the guide rail 3 in the second posture (such as... Figure 8 As shown), the back of the electrical equipment housing is fixed to the guide rail 3 in a second orientation, and the electrical equipment can be installed in the cabinet in a second orientation (such as the Y-direction orientation) through the guide rail 3.

[0059] The two snap fasteners 11 can also slide towards or away from each other to the third snap-fit ​​position, so as to assume a third snap-fit ​​posture (e.g. Figure 5 As shown), the first part of both clips 11 protrudes beyond the base 16 and can each be provided with an installation structure for cooperating with the cabinet, so that the back of the electrical equipment can be directly installed on the wall or cabinet to be installed without the need for installation via the guide rail 3.

[0060] Of course, the number of the snap fasteners 11 in this snap fastener assembly can be a single one, and the snap fastener assembly may also include a first snap seat; wherein, the first snap seat and the snap fastener 11 are disposed opposite to each other on the base 16, and the first snap seat is a fixed snap seat, the first snap seat can be designed as an integral part of the base, or it can be a separate part, and the first snap seat is fixed to the base by means of adhesive or other means; the snap fastener 11 is slidable relative to the base 16, and can slide to the above three snap-fit ​​positions respectively, when the snap fastener 11 slides to the second snap-fit ​​position, the guide rail 3 in the second posture can be snapped into place through the gap between the first snap seat and the snap fastener 11.

[0061] In other words, the snap-fit ​​assembly provided in this solution can be installed on the back of the electrical equipment housing. Its snap-fit ​​component 11 can be slidably mounted on the base 16 and can slide to three snap-fit ​​positions to present three different snap-fit ​​postures (working postures). When the snap-fit ​​component 11 is in the first snap-fit ​​posture, it can be used to snap the guide rail 3 through other snap-fit ​​components on the back of the electrical equipment housing. This posture is equivalent to a non-snap posture. When the snap-fit ​​component 11 is in the second snap-fit ​​posture, it can be used to snap the guide rail 3 in another posture. This posture is equivalent to a snap-fit ​​posture. When the snap-fit ​​component 11 is in the third snap-fit ​​posture, it can be installed in the cabinet of the electrical equipment through the mounting structure of the part protruding from the base 13. This posture is equivalent to a direct mounting posture. In this way, the electrical equipment using this snap-fit ​​assembly can present multiple postures (such as X-direction posture or Y-direction posture) or be installed in the cabinet in multiple ways (through guide rail installation or direct installation), thereby meeting the different installation requirements of the electrical equipment.

[0062] Furthermore, this embodiment of the invention also provides an electrical equipment housing, comprising: an electrical equipment housing body and a second snap-fit ​​assembly 2 disposed on the electrical equipment housing body, the electrical equipment housing further comprising the snap-fit ​​assembly as described above. The snap-fit ​​assembly is disposed on the electrical equipment housing body and is orthogonally distributed with the second snap-fit ​​assembly 2.

[0063] It should be noted that, as mentioned above, the snap-fit ​​component can be the first snap-fit ​​component 1, such as... Figure 1 As shown, it can be set on the back of the electrical equipment housing, and the second snap-fit ​​assembly 2 can also be set on the back of the electrical equipment housing. The first snap-fit ​​assembly 1 and the second snap-fit ​​assembly 2 are orthogonally distributed, that is, the connecting direction of the two snap-fit ​​pieces 11 of the first snap-fit ​​assembly 1 is perpendicular to the connecting direction of the two structures of the second snap-fit ​​assembly 2, so as to realize the snap-fit ​​of the guide rail 3 in different postures; for example, the guide rail 3 in the first posture can be snapped by the second snap-fit ​​assembly 2, and the guide rail 3 in the second posture can be snapped by the two snap-fit ​​pieces 11 that slide to the second snap-fit ​​position. Two latching components 11 are slidably mounted on the base 16 along a first direction. The two structural components of the second latching assembly 2 are mounted on the back of the electrical equipment housing along a second direction. The base 16 serves as the back of the electrical equipment housing (which can be rectangular). The first direction is parallel to the length of the back of the electrical equipment housing, and the second direction is parallel to the width of the back of the electrical equipment housing. Since this solution uses the aforementioned latching assembly, it also has corresponding beneficial effects, as detailed above. In other words, this design of the electrical equipment housing allows the electrical equipment to be installed in the cabinet in various configurations, and it can be installed via guide rails 3 or directly with screws.

[0064] In this plan, such as Figures 1 to 2 As shown, there are two sets of latching assemblies, located on both sides of the electrical equipment housing. The second latching assembly 2 includes a latch seat 21 and a second latch 22; the latch seat 21 and the second latch 22 are disposed opposite to each other on the electrical equipment housing; the line connecting the two latching members 11 intersects perpendicularly with the line connecting the latch seat 21 and the second latch 22.

[0065] It should be noted that, as Figure 1 As shown, the number of buckle assemblies can be two sets, that is, the number of buckle pieces 11 can be two. The two buckle pieces 11 can be slidably disposed on both sides of the base 16 along the first direction. The base 16 can serve as the back of the electrical equipment housing. The card seat 21 and the second buckle 22 can be disposed on both sides of the back of the electrical equipment housing along the second direction, and the first direction and the second direction intersect perpendicularly. That is, the line connecting the two buckle pieces 11 intersects perpendicularly with the line connecting the card seat 21 and the second buckle 22.

[0066] When the two latching pieces 11 slide towards each other until they engage with the two first latching slots 12 one by one, as Figure 7As shown, the card holder 21 and the second buckle 22 can be used to clamp the guide rail 3 in the first posture. When the two buckle pieces 11 slide back to back and engage with the two second card slots 13 one by one, the two buckle pieces 11 can be used to clamp the guide rail 3 in the second posture. When the two buckle pieces 11 slide back to back and engage with the two third card slots 14 one by one, the first part of the two buckle pieces 11 protrudes out of the base 16, that is, out of the back of the electrical equipment housing. The mounting holes 111 of the first part of the two buckle pieces 11 can be installed in the cabinet by two screws. Of course, the buckle assembly and the second buckle assembly 2 are designed in this way so that the back of the electrical equipment housing can be installed on the guide rail 3 in different postures, or the back of the electrical equipment housing can be directly installed in the cabinet by screws.

[0067] Specifically, such as Figure 6 As shown, the main body of the electrical equipment housing has a fourth slot 23, and the second buckle 22 is installed in the fourth slot 23. As mentioned above, the mounting base 21 is a fixed mounting base. To facilitate the mounting of the guide rail 3 in its first position, the second buckle 22 is detachably mounted on the main body of the electrical equipment housing (i.e., the base 16). Correspondingly, the main body of the electrical equipment housing may have a fourth slot 23, the structure of which can be referred to... Figure 6 As shown, after the guide rail 3 in the first posture is placed on the main body of the electrical equipment housing, the second buckle 22 can be engaged in the fourth slot 23 along the second direction, and together with the card seat 21, the guide rail 3 in the first posture is clamped.

[0068] The first, second, and third snap-fit ​​stations are located on both sides of the line connecting the card holder 21 and the second snap fastener 22, with the first snap-fit ​​station located between the second snap-fit ​​stations and the second snap-fit ​​station located between the third snap-fit ​​stations.

[0069] It should be noted that, as mentioned above, the three clamping stations can be designated as the first clamping station, the second clamping station, and the third clamping station; among them, if... Figure 4 As shown, the first snap-fit ​​station includes two first snap-fit ​​slots 12, which are arranged opposite to each other on both sides of the line connecting the snap-fit ​​base 21 and the second snap-fit ​​22 along the first direction; the second snap-fit ​​station includes two second snap-fit ​​slots 13, which are arranged opposite to each other on both sides of the line connecting the snap-fit ​​base 21 and the second snap-fit ​​22 along the first direction, and are located outside the two first snap-fit ​​slots 12; the third snap-fit ​​station includes two third snap-fit ​​slots 14, which are arranged opposite to each other on both sides of the line connecting the snap-fit ​​base 21 and the second snap-fit ​​22 along the first direction, and are located outside the two second snap-fit ​​slots 13; thus, as Figure 1 As shown, when the two fasteners 11 slide towards each other to the first fastening station, they are in the first fastening posture. At this time, the fastening gap between the two fasteners 11 is minimized, and the guide rail 3, which is in the second posture, cannot be fastened. Figure 7As shown, the guide rail 3 in the first position can be engaged by the card holder 21 and the second buckle 22; as Figure 3 As shown, when the two fasteners 11 slide back to back to the second fastening position, they are in a second fastening posture. At this time, the fastening gap between the two fasteners 11 is appropriate, which can fasten the guide rail 3 (such as...) in the second posture. Figure 8 As shown); Figure 5 As shown, when the two fasteners 11 slide back to back to the third fastening position, they are in the third fastening posture. At this time, the fastening gap between the two fasteners 11 is maximized. The first part of both fasteners 11 protrudes from the back of the electrical equipment housing (i.e., the base 16). Then, the mounting holes 111 of the first part of the two fasteners 11 are installed into the cabinet one by one by two screws, so that the electrical equipment housing can be directly installed into the cabinet.

[0070] Furthermore, such as Figure 1 As shown, when the two latching parts 11 slide to the first latching position, they are completely retracted into the base. For example, Figure 1 As shown, when the two latching pieces 11 slide to engage with the two first latching slots 12 one by one, the two latching pieces 11 are completely located on the base 16 and do not protrude from the base 16. This not only saves the installation space on the back of the electrical equipment housing, but also makes the back of the electrical equipment housing look neat when the guide rail 3 in the first posture is latched on the second latching assembly 2. Of course, when the two first latching pieces 11 slide to engage with the two third latching slots 14 one by one, the first part of the two first latching pieces 11 protrudes from the base 16, and the remaining part is located on the base 16.

[0071] In other words, the snap-fit ​​assembly provided in this solution has the following three working conditions:

[0072] In the first working condition, when the horizontal guide rail 3 is attached to the second latching assembly 2 on the back of the electrical equipment housing, that is, when the back of the electrical equipment housing is horizontally mounted on the guide rail 3, the back of the electrical equipment housing is fixed to the guide rail 3 by the second latching assembly 2. The two latching pieces 11 of the latching assembly slide to engage with the two first latching slots 12 one by one, that is, slide completely to the back of the electrical equipment housing, saving installation space.

[0073] In the second working condition, when the vertical guide rail 3 is attached to the buckle assembly on the back of the electrical equipment housing, that is, when the back of the electrical equipment housing is vertically mounted on the guide rail 3, the two buckle pieces 11 of the buckle assembly slide to engage with the two second buckle slots 13 one by one, that is, the back of the electrical equipment housing is fixed on the guide rail 3 by the two buckle pieces 11.

[0074] In the third working condition, when there is no guide rail 3, the two clips 11 slide to engage with the two third slots 14 one by one, and then the mounting holes 11 protruding from the two clips 11 are fixed one by one by two screws, so as to directly fix the back of the electrical equipment housing to the wall or cabinet to be installed.
