[0048] The relay function part 300 comprises a relay box 310 and a relay terminal block 320, the upper surface of the relay terminal block 320 is provided with a socket groove 321, the relay box 310 is detachably connected to the socket groove 321, the relay box 310 is in the shape of a regular quadrangular prism, the four side surfaces of the relay box 310 are respectively provided with a first clamping matching structure 311 at the same height, the width size of the relay box 310 is consistent with the distance between the two vertical plates 120, wherein the shape of the first clamping matching structure 311 corresponds to the clamping structure 121;

[0049] The interval between the two clamping structures 121 on the vertical plate 120 is greater than the width size of the relay function part 300, and the distance between the clamping structure 121 close to the middle bottom plate 110 and the middle bottom plate 110 is greater than half of the width size of the relay function part 300.

[0050] In the prior art, the intermediate relay includes a relay part and a terminal block part connected with each other, the relay part is used to control external circuit, and the terminal block part is used to simplify the process of wire connection; during installation of multiple intermediate relays, the intermediate relays are usually connected in series on the installation rail 400; specifically, the fixing mode of the intermediate relay is not selectable, the terminal block part is connected to the installation rail 400, and the direction of the terminal block part is fixed, which is not conducive to the process of wire connection and the process of space layout, and the installation direction of the entire intermediate relay is fixed, so that the installation of the intermediate relay cannot be realized under certain space conditions, and the space array of multiple relays cannot be realized either; meanwhile, a single installation rail 400 can only fix a row of relays, and the utilization rate of space is low; and when multiple installation rails 400 are used together, the direction of the terminal block part is not changeable, which has greater negative impact on the process of wire connection and the process of wire position layout.

[0051] In the embodiment, the relay function part 300 includes a relay box 310 and a relay terminal block 320, the relay terminal block 320 is provided with a socket groove 321 on the upper surface, and the relay box 310 is detachably connected to the socket groove 321. The mounting card 100 is used to fix the relay function part 300 as the structural basis of the relay assembly, and the clamping structure 121 of the inner wall of the vertical plate 120 corresponds to the first clamping matching structure 311 of the side surface of the relay box 310, so that the mounting card 100 can better fix the relay function part 300. For example, the clamping structure 121 is a protruding structure (such as a square or a cross shape), and the first clamping matching structure 311 is a corresponding recessed structure. The model of the relay function part 300 can be fixed, and when the installation environment changes, only the model of the mounting card 100 needs to be adjusted, and the difficulty of adjusting the structure of the mounting card 100 is greatly reduced compared with the complex structure of the relay terminal block 320.

[0052] In the embodiment, the back plate sliding groove 111 penetrating the width direction of the intermediate bottom plate 110 is arranged on the back surface of the intermediate bottom plate 110, the back plate sliding groove 111 is arranged at the middle of the length direction of the intermediate bottom plate 110, and the back plate sliding groove 111 forms the fixing basis of the mounting card 100; and the mounting groove 112 is arranged on the back surface of the intermediate bottom plate 110, and the slidable elastic clamping block 200 is arranged in the mounting groove 112. The elastic fixing structure is arranged between the elastic clamping block 200 and the intermediate bottom plate 110, the elastic fixing structure limits the sliding of the elastic clamping block 200 to the outer end of the length direction of the elastic clamping block 200, and then the elastic clamping block 200 forms a elastic tongue type structure. The elastic clamping block 200 and the first clamping structure 113 can be elastically clamped to the installation rail 400, and the elastic mounting characteristic of the elastic clamping block 200 enables the mounting card 100 to be penetrated from the length direction of the installation rail 400 and directly clamped from the surface of the installation rail 400.

[0053] In the embodiment, the installation mode of the relay function part 300 has multiple, the following focuses on several, according to the installation position of the relay terminal block 320, first divided into internal type (the relay terminal block 320 is at least partially in the installation card 100) and external type (the relay terminal block 320 is all outside the installation card 100). Internal type includes the positive internal type of the relay terminal block 320 combined with the intermediate bottom plate 110 (the most conventional structure at present); And the inverted internal type of the relay box 310 corresponding to the intermediate bottom plate 110, the relay terminal block 320 parallel to the intermediate bottom plate 110. External type also includes horizontal external type and vertical external type, in which the length direction of the relay terminal block 320 is perpendicular to the length direction of the installation card 100, and in the vertical external type, the length direction of the relay terminal block 320 is parallel to the length direction of the installation card 100. When the installation position of the relay function part 300 is external type, there are also cases of the relay box 310 on the top and on the bottom. According to the above introduction of the installation mode of the relay function part 300, it can also be seen that the position of the relay function part 300 in the application is optimized to a large extent, and the space utilization in the installation process of the relay function part 300 can also be optimized by targeted configuration.

[0054] In the embodiment, when the installation position of the relay function part 300 is internal type, the two vertical plates 120 clamp the relay function part 300 to form fixation, and further, when the relay function part 300 is inverted internal type, the relay terminal block 320 is exposed at the position close to the opposite outer side, which is beneficial for the user to complete the wire connection process, especially when the structure of the relay terminal block 320 is specially designed (described in subsequent embodiments), the wire connection process can be further reduced.

[0055] In the embodiment, in addition to when the relay function part 300 is inverted internal type, the relay terminal block 320 is exposed, when the relay function part 300 is external type, the relay terminal block 320 is also exposed, which reduces the difficulty of wire connection and provides the possibility of wiring diversity. In the prior art, due to the shielding of the relay box 310, it is difficult to perform multi-layer wiring, in the application, when the relay function part 300 is external type, the blocking of the relay box 310 is avoided, which provides the possibility of multi-layer wiring of the wire.

[0056] In this embodiment, when it is lateral external, there are two clamping structures 121 on the mounting card 100, which can be selected to have different fixed position options; the distance between the clamping structure 121 close to the middle bottom plate 110 and the middle bottom plate 110 is greater than half the width dimension of the relay function part 300, so that the mounting space of the relay box 310 is provided; the interval between the two clamping structures 121 on the stand plate 120 is greater than the width dimension of the relay function part 300, so that two relay function parts 300 can be fixed on the mounting card 100 in a lateral external manner. It should be noted that when multiple relay assemblies are fixed side by side on the mounting rail 400, the relay function part 300 is installed in a lateral external manner, the connection of the wires can be parallel to the mounting rail 400, so that the volume occupied by the overall installation is reduced; especially when multiple parallel mounting rails 400 are needed to set up an array structure, the above wire parallel to the mounting rail 400 is set up, so that the overall wiring setting is more compact. And the relay box 310 is limited to a regular quadrangular prism shape, so that the fixing method of the relay box 310 on the mounting card 100 is flexible, such as in the external type, the relay terminal block 320 can be perpendicular to the height direction of the stand plate 120 or perpendicular to the height direction of the stand plate 120.

[0057] In order to stably realize the above various fixing methods, certain structural improvements may be needed, which will be described in detail in subsequent embodiments.

[0058] In summary, the mounting card 100 fixes the relay function part 300 as the structural basis of the relay assembly, and the model of the relay function part 300 can be fixed. When the installation environment changes, only the model of the mounting card 100 needs to be adjusted; the mounting method of the relay function part 300 on the mounting card 100 has multiple options, which provides multiple possibilities for wire connection and wire layout, and also provides the possibility for full use of space during the installation process of the relay function part 300.

[0059] Reference Figures 5 to 8 In one embodiment, two sides of the relay terminal block 320 are provided with a fixing groove 322 penetrating the height direction of the relay terminal block 320, wherein the width dimension of the fixing groove 322 corresponds to the width dimension of the stand plate 120.

[0060] In this embodiment, the side of the relay terminal block 320 is provided with a fixing groove 322, and when the mounting position of the relay function part 300 is internal, the mounting card 100 limits the relay terminal block 320 through the fixing groove 322 on the side of the relay terminal block 320; and the relay box 310 and the mounting card 100 are also fixed, at this time the stability of the combination between the entire relay function part 300 and the mounting card 100 is improved.

[0061] In one embodiment, the length of the relay function part 300 is less than twice the width of the mounting card 100.

[0062] First, the external mounting includes horizontal external mounting and vertical external mounting, in the horizontal external mounting, the length direction of the relay terminal block 320 is perpendicular to the length direction of the mounting card 100, in the vertical external mounting, the length direction of the relay terminal block 320 is parallel to the length direction of the mounting card 100; second, when the mounting position of the relay function part 300 is externally mounted, there are also cases where the relay box 310 is on top and on the bottom. In the use environment, there are cases where multiple relay function parts 300 are arranged side by side, as known from the foregoing embodiments, there are two positions of the horizontal external mounting relay function part 300 on the mounting card 100 (that is, the positions of the two card joint structures 121), then by staggering the installation of a relay function part 300 on different mounting cards 100, multiple relay function parts 300 can be fixed and arranged side by side in a horizontal external mounting manner (the distance gap between the mounting cards 100 is as small as possible), but the above is a waste of the installation position of the two horizontal external mountings. In this embodiment, the length of the relay function part 300 is reduced, and the length of the relay function part 300 is limited to less than twice the width of the mounting card 100, so that the positions of the two horizontal external mountings can be utilized at the same time. Specifically, the relay box 310 is staggered on top and on the bottom on adjacent mounting cards 100, so that the space on both sides of the relay function part 300 in the length direction increases, and when the length of the relay function part 300 is less than twice the width of the mounting card 100, the relay function part 300 is installed in the position of the two horizontal external mountings, and the staggered installation method is not used to waste space.

[0063] Referring to Figures 5 to 8 In one embodiment, the two sides of the relay terminal block 320 are respectively provided with a second card joint matching structure 323, and the relative positions between the first card joint matching structure 311 and the second card joint matching structure 323 on the relay function part 300 are consistent with the relative positions between the two card joint structures 121 on the stand 120.

[0064] In the foregoing embodiments, the fixing groove 322 of the relay terminal block 320 can assist in fixing the relay function part 300 by the mounting card 100; in this embodiment, the auxiliary fixing effect realized by the second card joint matching structure 323 is better. When the relay function part 300 is a positive internal mounting or an inverted internal mounting, the first card joint matching structure 311 and the second card joint matching structure 323 can respectively form a fixing with the two card joint structures 121 on the stand 120, at this time, the fixing effect of the relay function part 300 can be enhanced.

[0065] Referring to Figures 13 to 20 In one embodiment, the socket slot 321 penetrates from the upper surface of the relay terminal block 320 to the lower surface of the relay terminal block 320.

[0066] In the specific structure of the relay terminal block 320, the bottom of the relay box 310 is provided with a plurality of electrode pins, the inside of the relay terminal block 320 is provided with a plurality of electrode connecting elastic cards, the position of the socket slot 321 corresponds to the electrode connecting elastic card, so that when the relay box 310 is connected to the socket slot 321, the electrode pins of the relay box 310 can be connected with the electrode connecting elastic card; the outside of the relay terminal block 320 is provided with a plurality of terminal posts, and the electrode connecting elastic card is correspondingly electrically connected to the terminal post, so that the relay function part 300 is completed. In this embodiment, the socket slot 321 penetrates the thickness direction of the relay terminal block 320, so that the relay box 310 can be connected to the upper surface of the relay terminal block 320 or the lower surface. In this application, the installation mode of the relay function part 300 is various, so that the above-mentioned flexibility of the relay terminal block 320 is very advantageous for the wiring of the relay function part 300. When the relay function part 300 is inverted and installed, the above-mentioned socket slot 321 is provided in a penetrating manner, so that the wire connection operation can be performed on the outermost side. Compared with the traditional wiring mode, in this application, when the wire connection of the relay function part 300 is completed, the side of the relay terminal block 320 facing the relay box 310 is not conducive to operation and the arrangement of the wire position, and in this embodiment, the penetrating arrangement of the socket slot 321 makes the wire connection can be on the side facing the relay box 310 or on the side facing away from the relay box 310, and the specific implementation is realized by the forward and reverse installation of the relay terminal block 320. In particular, when the relay terminal block 320 is trapezoidal, the relay terminal block 320 can be installed forward and backward, which is very advantageous, which will be described in subsequent embodiments.

[0067] Referring to Figures 13 to 20 In one embodiment, the relay terminal block 320 includes a first terminal layer 324 and a second terminal layer 325 stacked with each other, one side of the first terminal layer 324 is the upper surface of the relay terminal block 320, and one side of the second terminal layer 325 is the lower surface of the relay terminal block 320, wherein the first terminal layer 324 is shorter than the second terminal layer 325, and the first terminal layer 324 is arranged at the middle of the length direction of the second terminal layer 325.

[0068] When the installation mode of the relay function part 300 is the built-in type, the relay terminal block 320 is inside the installation card 100, and it is advantageous for the relay terminal block 320 to be installed in the normal direction, that is, the relay box 310 is connected to the first terminal layer 324, and at this time, the surfaces of the first terminal layer 324 and the second terminal layer 325 can be directed toward the operator during the wire connection operation; when the installation mode of the relay function part 300 is the external type, the relay terminal block 320 is outside the installation card 100, and it is advantageous for the relay terminal block 320 to be installed in the reverse direction, that is, the relay box 310 is connected to the second terminal layer 325, and at this time, the surfaces of the first terminal layer 324 and the second terminal layer 325 are still directed toward the operator during the wire connection operation.

[0069] With reference to Figure 5 and 10 In one embodiment, the top of the relay box 310 is provided with a hanging edge 312 at both ends in the length direction of the relay function part 300.

[0070] In the present embodiment, when the installation position of the relay function part 300 is the external type, there are also cases in which the relay box 310 is on top and below; when the relay box 310 is on top, the hanging edge 312 can form a hanging fit with the vertical plate 120, and at this time, the fixing of the relay function part 300 on the installation card 100 is more stable. The above processing of the hanging edge 312 can be completed in one piece during the processing of the shell of the relay box 310.

[0071] In one embodiment, the width dimension of the vertical plate 120 is consistent with the distance dimension from the hanging edge 312 to the relay terminal block 320.

[0072] In the present embodiment, the width dimension of the vertical plate 120 is limited, and then when the installation position of the relay function part 300 is the external type and the relay box 310 is below, the relay terminal block 320 can play a hanging role, thereby assisting the fixing of the relay function part 300 on the installation card 100.

[0073] In one embodiment, the height dimension of the vertical plate 120 is consistent with the distance dimension from the hanging edge 312 to the relay terminal block 320.

[0074] In the present embodiment, the height dimension of the vertical plate 120 and the height dimension of the relay box 310 are limited, and at this time, when the installation position of the relay function part 300 is the built-in type, the hanging edge 312 can also play an auxiliary fixing role.

[0075] With reference to Figures 1 to 4In one embodiment, the elastic clamping block 200 is provided with a hollow space 220 penetrating the thickness direction of the elastic clamping block 200 at the middle position of the elastic clamping block 200, the middle bottom plate 110 is provided with a limiting hole 115 at the position corresponding to the hollow space 220, the hollow space 220 is connected with an elastic member 230 between the two ends of the length direction of the elastic clamping block 200, the elastic member 230 comprises a clamping shaft 231 provided at the middle of the length direction of the elastic member 230, the clamping shaft 231 is provided corresponding to the limiting hole 115, and the elastic member 230 and the limiting hole 115 form the elastic fixing structure, wherein the elastic member 230 is deformed in the length direction of the elastic clamping block 200.

[0076] In different embodiments, the elastic member 230 and the elastic clamping block 200 can be a split structure or an integral structure, and the movement of the elastic clamping block 200 is limited by the extension and deformation of the elastic member 230. In the embodiment, the elastic member 230 and the elastic clamping block 200 are an integral structure, the clamping shaft 231 is in the limiting hole 115, so that the position of the clamping shaft 231 is limited, and when the position of the elastic clamping block 200 changes, the elastic force of the elastic member 230 provides a reverse action, so as to realize the elastic sliding of the elastic clamping block 200 in the mounting groove 112, and the structure is simple and reliable.

[0077] Referring to Figure 12 In one embodiment, the vertical plate 120 is provided at the position of two-fifths to three percent of the length direction of the middle bottom plate 110.

[0078] In the embodiment, by setting the position of the vertical plate 120 to be asymmetric, the fixing direction of the mounting clamping block 100 on the mounting rail 400 can also be selected to be upward or downward, and the installation directions of adjacent mounting clamping blocks 100 can also be different, so that the space provided by the wire installation process of the relay function part 300 is larger when the relay function part 300 is installed in a horizontal external manner.

[0079] In summary, the relay assembly with optimized installation position provided by the application fixes the relay function part 300 as the structural basis of the relay assembly, the model of the relay function part 300 can be fixed, and when the installation environment changes, only the model of the mounting clamping block 100 needs to be adjusted; the installation mode of the relay function part 300 on the mounting clamping block 100 has multiple modes, which provides multiple possibilities for wire connection and wire layout, and also provides the possibility for full use of the space of the relay function part 300 during the installation process.
