[0037] The technical solution of the utility model is further described in detail below through the accompanying drawings and embodiments.
[0038] Figure 1 A schematic diagram of a modular connector structure provided by an embodiment of the utility model, such as Figure 1 As shown, the modular connector includes a fixed connector 1 and a free connector 2. The structures and functions of the fixed connector 1 and the free connector 2 are specifically introduced below.
[0039] First, combine Figures 2 to 4 The fixed connector 1 is introduced. The fixed connector 1 is used to be installed on a fixed component (system end) of a device, and specifically includes a bracket component 11 and a module component 12.
[0040] The bracket assembly 11 is used to fix the module assembly 12. The bracket assembly 11 includes a bracket body 111 provided with a plurality of module mounting holes 113, and a first sealing ring 112 arranged on the outer wall of the bracket body 111. It should be noted that the module mounting holes 113 are used to install the module 121, and the first sealing ring 112 is used to achieve the sealing of the fixed connector 1 and the free connector 2. The two ends of the bracket body 111 are respectively provided with guide holes 114, which are used to cooperate with the guide column 21 of the free connector 2 to achieve the guidance and mis-insertion prevention when the fixed connector 1 and the free connector 2 are plugged in. It can be understood that the plurality of module mounting holes 113 of the bracket are arranged between the two guide holes 114, and the guide holes 114 are designed at both ends of the bracket for easier guidance. The outer wall of the bracket body 111 is provided with a first keyway 115, which is used to cooperate with the second key 22 of the free fixer to further achieve the guidance and mis-insertion prevention when the fixed connector 1 and the free connector 2 are plugged in. The inner wall 1130 of the module mounting hole is provided with a plurality of first keys 116, which are used for guiding, fixing and mis-insertion prevention when the module 121 is assembled. The two ends of the inner wall 1130 of the module installation hole are respectively provided with positioning claws 117, which extend from the inner wall into the cavity, and the longitudinal direction of the positioning claws 117 is at a certain angle to the axis of the product, thereby achieving the fixation of the module 121. It should be noted that the first key 116 and the positioning claws 117 are distributed on different surfaces of the inner wall 1130 of the module installation hole, so as not to interfere with each other.
[0041] The module assembly 12 specifically includes a plurality of modules 121, each module 121 corresponds to a module mounting hole 113, and the module assembly 12 can be installed into the module mounting hole 113 of the bracket according to the key position design rule to prevent mis-insertion, and the installation position of each module assembly 12 is fixed. Specifically, the outer wall of the module 121 is provided with a plurality of second key slots 122 that cooperate with the first key 116 on the inner wall 1130 of the module mounting hole. Preferably, the number of the first keys 116 is at least two, and the installation positions of the first keys 116 provided on the inner wall 1130 of each module mounting hole are different and arranged according to a certain rule. Correspondingly, the positions of the second key slots 122 provided on the outer wall of each module 121 are arranged differently, thereby ensuring that the module 121 cannot be installed by mistake. The outer wall of the module 121 is also provided with a second sealing ring 123 that cooperates with the inner wall 1130 of the module mounting hole, and the second sealing ring 123 is used to achieve sealing between the module 121 and the bracket. Combination Figure 5 and Figure 6 As shown, both ends of the outer wall of the module 121 are respectively provided with positioning steps 124 that are engaged with the positioning claws 117 on the inner wall 1130 of the module mounting hole. Preferably, a flange 1210 is provided on the main body of the module 121, and the second sealing ring 123 is arranged between the flange 1210 and the positioning step 124.
[0042] It should be noted that, combined with Figure 7 and Figure 8 As shown, a plurality of contact holes 126 and contact members 125 assembled in the contact holes 126 are provided in the module 121. In some preferred embodiments, the contact holes 126 are multi-section holes, and the diameters of the sections are different, thereby forming a limiting step. In a specific example, a first limiting step 1261 and a second limiting step 1262 are provided in the contact hole 126; the outer wall of the contact member 125 is provided with a contact outer claw 1251 that cooperates with the first limiting step 1261, and is also provided with a third limiting step 1252 that cooperates with the second limiting step 1262, thereby realizing the assembly of the contact member 125 in the module 121.
[0043] When the module assembly 12 is assembled with the bracket assembly 11, the second key groove 122 on the outer wall of the module 121 is matched with the first key 116 on the inner wall 1130 of the module mounting hole, and the second sealing ring 123 cooperates with the inner wall 1130 of the module mounting hole, thereby achieving sealing between the module assembly 12 and the bracket assembly 11; after the module 121 is installed in the bracket, the positioning claw 117 of the module 121 is stuck on the positioning step 124 on the inner wall of the bracket body 111, so that the module 121 cannot fall out.
[0044] Secondly, combined Fig. 9 and Fig.10As shown, the free connector 2 is introduced. The free connector 2 is installed on the movable part (module end) of the device and is plugged with the fixed connector 1 through the pin 25. The two ends of the free connector 2 are respectively provided with guide columns 21 that match the guide holes 114 of the bracket body 111 of the fixed connector 1, and the main body of the free connector 2 is provided with a second key 22 that matches the first key groove 115 of the bracket body 111 of the fixed connector 1.
[0045] When the free connector 2 and the fixed connector 1 are plugged in, the guide column 21 of the free connector 2 cooperates with the guide hole 114 of the fixed connector 1 to achieve guidance during plugging; at the same time, the first key slot 115 of the bracket body 111 cooperates with the second key 22 of the free connector 2 to prevent mis-plugging; further, the first sealing ring 112 cooperates with the inner wall 20 of the free connector to achieve sealing, thereby achieving sealing of the free connector 2 and the fixed connector 1.
[0046] In some preferred embodiments, in order to prevent the free connector 2 and the fixed connector 1 from being inserted into each other by mistake, the cross-sectional shapes of the guide hole 114 and the guide column 21 are limited. Specifically, Fig.10 and 11 As shown, the cross-section of the guide hole 114 of the bracket body 111 is an asymmetric shape, and the cross-section of the guide column 21 is an asymmetric shape. It can be understood that the first inner angle 1141 and the second inner angle 1142 of the guide hole 114 are different in size, and the corresponding first outer angle 211 and the second outer angle 212 of the guide column 21 are also different in size.
[0047] In some preferred embodiments, in order to ensure the locking of the free connector 2 and the fixed connector 1, a locking screw 127 may be provided on the fixed connector 1, and a locking nut 23 cooperating with the locking screw 127 may be provided on the free connector 2, so that after the plug and the socket are plugged in, they are locked by two pairs of locking screws 127 and nuts.
[0048] In some preferred embodiments, Figure 2 , Fig.10 and Fig.12As shown, the connector also has a floating installation function. Specifically, a first installation panel 13 is installed on the fixed connector 1. The first installation panel 13 here refers to the installation panel on which the device to be installed is installed together with the fixed connector 1. Flanges 128 are also provided at both ends of the bracket body 111 of the fixed connector 1. At least two floating installation screws 129 are provided on the flange 128. The bracket body 111 and the first installation panel 13 are fixed by the floating installation screws 129. That is, the first installation panel 13 and the bracket body 111 are floatingly installed. Specifically, the floating There is a gap between the head of the mounting screw 129 and the flange 128 of the bracket body 111, and there is a gap 1290 between the screw mounting hole of the fixed connector 1 and the radial direction of the floating mounting screw 129. It can be understood that the diameter of the part of the screw that penetrates the hole is smaller than the inner diameter of the mounting hole, and the axial length is greater than the thickness of the mounting flange 128. The screw only limits part of the degree of freedom, so that after locking the panel, the fixed connector 1 can have a certain amount of movement, that is, the floating amount; further, an anti-misinstallation column 1110 is also provided on the bracket body 111 to prevent the first mounting panel 13 from being misinstalled. The mounting surface 200 of the free connector 2 is fixedly installed with the second mounting panel 24, that is, the second mounting panel 24 and the free connector 2 are fixedly installed. The second mounting panel 24 here refers to the mounting panel where the device to be installed is installed together with the free connector 2. Further, an anti-misinstallation column 26 is also provided on the free connector body to prevent the second mounting panel 24 from being misinstalled. During plugging, the free connector 2 is installed on the movable part (module end) of the device, and the fixed connector 1 is installed on the fixed part (system end) of the device. There will be size or position errors between the two parts. If the connector and the mounting panel are fixed and cannot move, the free connector 2 and the fixed connector 1 will not be aligned when plugged in. Specifically, the outer shells of the connectors collide with each other, and the contacts 125 cannot be plugged in one by one. In this embodiment, the fixed connector 1 and the first mounting panel 13 are loosely matched, and the fixed connector 1 and the first mounting panel 13 can move relative to each other. In this way, when the free connector 2 and the fixed connector 1 are plugged in, the guide column 21 and the guide hole 114, the key and the key slot can correct the position of the fixed connector 1, so that the contact 125 can be aligned and plugged in normally.
[0049] Furthermore, the first key 116 and the first key slot 115 extend from the end of the bracket toward the mounting surface 110 but do not extend to the mounting surface 110 . Furthermore, the first sealing ring 112 is disposed between the first key slot 115 and the mounting surface 110 , thereby achieving sealing between the fixed connector 1 and the free connector 2 .
[0050] It can be seen that the modular connector provided by the embodiment of the utility model has the following advantages:
[0051] 1. Modular structure. Both free connectors and fixed connectors can be designed into modular structures according to product requirements.
