Technical Field
[0001] This utility model relates to the field of electrical connectors, and in particular to a wiring module connector. Background Technology
[0002] I / O module connectors are critical interfaces between computer systems and external devices (such as sensors, actuators, and displays), responsible for the stable and reliable transmission of data signals and power between internal systems and external devices. They offer diverse interface types, such as the common RJ45, USB, and D-Sub, as well as M8 / M12 circular connectors suitable for industrial fieldbuses, to meet different communication protocols and device connection requirements. To cope with harsh application scenarios such as industrial environments, many I / O connectors are designed with a compact structure and provide high-level sealing protection such as IP67, giving them excellent vibration resistance, shock resistance, and dust and water resistance. Therefore, I / O module connectors are widely used in industrial automation, robotics, PLC control, building automation, and the Internet of Things (IoT).
[0003] Traditional wiring module connectors mainly consist of a plastic housing and various male and female conductive sections (i.e., I / O interfaces) distributed on the housing. Each conductive section contains a conductive terminal that protrudes from the inside of the housing. As a delicate core component for conducting electrical signals, ensuring the proper functioning of the conductive terminals is crucial. To facilitate the installation and arrangement of the conductive terminals and other components, the housing includes a main body and a removable back cover. However, gaps exist between the back cover and the main body for installation purposes. These gaps can easily allow dust and water vapor to enter, affecting the lifespan of the conductive terminals. On the other hand, simply placing a waterproof ring between the back cover and the main body can easily lead to deformation due to the flexibility of the waterproof ring. Utility Model Content
[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a wiring module connector to solve the waterproofing problem between the existing main body and the back cover.
[0005] To solve the above-mentioned technical problems, the present invention provides a wiring module connector comprising a plastic housing having an internal accommodating cavity and extending rearward to form an open side, a rear cover for covering the open side, and a conductive module disposed on the plastic housing. A support portion protrudes from the inner wall of the accommodating cavity near the open side, and the support portion and the open side form a rear cavity. The rear cover is installed in the rear cavity and forms a sealing cavity with the support portion. A sealing ring is provided in the sealing cavity to seal the accommodating cavity with the rear cover.
[0006] Furthermore, the support portion includes a support portion that protrudes around the inner wall of the accommodating cavity and is used to support the sealing ring, the sealing ring having an outer ring portion corresponding to the support portion and being pressed onto it by the rear cover; the support portion also includes a plurality of first inner protruding portions that protrude inward from the support portion and are spaced apart, the sealing ring having a first inner extension portion corresponding to the first inner protruding portion and being pressed onto it by the rear cover.
[0007] Furthermore, the outer ring portion has a protruding positioning post, and the support portion has a recessed positioning hole for the positioning post to be inserted into.
[0008] Furthermore, the first inner protrusion, the first inner extension, and the rear cover are coaxially provided with a first threaded hole for screws to fix the rear cover and the sealing ring to the support.
[0009] Furthermore, the rear cover has a pressing portion that protrudes from the contour of the sealing ring for overlapping and pressing the sealing ring onto the support portion.
[0010] Furthermore, the pressing part is provided with a partition strip distributed around the inner edge of the pressing part, and the first threaded hole on the rear cover is located on the periphery of the partition strip.
[0011] Furthermore, the supporting portion has a second inner protrusion extending inward on opposite sides, and the sealing ring has a second inner extension corresponding to the second inner protrusion, which is pressed against the rear cover; the second inner protrusion, the second inner extension, and the rear cover are coaxially provided with a second threaded hole for screws to fix the rear cover and the sealing ring to the plastic housing.
[0012] Furthermore, the conductive module has a male terminal interface, a first female terminal interface, and multiple second female terminal interfaces arranged in a rectangular array on the front side of the plastic housing. A nameplate is provided between two adjacent second female terminal interfaces in each column and between the second female terminal interfaces and the male terminal interface. A mating groove is recessed on the front side of the plastic housing corresponding to the position of the nameplate. Multiple protrusions are provided in the mating groove, and a spacer cavity is formed between the multiple protrusions. The nameplate is installed in the mating groove, and a locking block is formed on the nameplate for locking into the spacer cavity.
[0013] Furthermore, multiple light guide pillars are arranged in an array between two adjacent second female end interfaces in each row; the light guide pillars are made of transparent material.
[0014] Furthermore, a first boss is provided at the position corresponding to the male interface, the first female interface, and the second female interface within the accommodating cavity, and the first boss is integrally connected to the support portion; a first insertion cavity is formed on the first boss along a insertion direction, penetrating the front side of the plastic shell and the first boss; the conductive module includes a single male connector, a first female connector, and a second female connector inserted into each of the first insertion cavities; the male connector, the first female connector, and the second female connector each have a first insertion portion, a second insertion portion, and a second insertion portion; the first insertion portion extends out of the front side to form the male interface with the first insertion cavity; the second insertion portion extends out of the front side to form the first female interface with the first insertion cavity; and the second insertion portion extends out of the front side to form the second female socket with the first insertion cavity.
[0015] The wiring module connector of this utility model has at least the following beneficial effects: by setting a support part, the support part and the back cover cannot be used for the hidden installation of the back cover. At the same time, it can also provide support for the back cover and the sealing ring. The support part and the back cover can achieve the sealing of the accommodating cavity by clamping the sealing ring in it. Moreover, the clamping and support of the waterproof ring by the support part and the back cover also greatly limits the deformation of the waterproof ring, improves the sealing performance and the service life of the waterproof ring.

Detailed Implementation
[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] Please see Figures 1 to 4 The wiring module connector of this utility model includes a plastic housing 1 with an internal accommodating cavity 11 and an open side 122 extending rearward, a rear cover 2 for covering the open side 122, a sealing ring 3 between the plastic housing 1 and the rear cover 2, and a conductive module disposed on the plastic housing 1.
[0019] Please see Figure 3 , Figure 4 and Figures 6 to 11The plastic shell 1 can be formed by plastic injection molding and is in the shape of a cuboid. Therefore, the plastic shell 1 has length, width, and height (or thickness). The two sides of the plastic shell 1 along the height direction are respectively configured as the front side 121 and the rear side. The interior of the plastic shell 1 is hollow to form the receiving cavity 11, and the receiving cavity 11 extends through the rear side of the plastic shell 1, and the receiving cavity 11 forms an open side 122 on the rear side. The rear cover 2 can be directly placed on the edge of the open side 122. However, in order to make the installation of the rear cover 2 more secure and convenient, a support part 13 is provided on the inner wall of the accommodating cavity 11. The support part 13 extends evenly from the side of the accommodating cavity 11 facing the front side 121 along the height direction toward the rear side and is shorter than the accommodating cavity 11 near the open side 122, so that the support part 13 and the open side 122 form a step-like shape, so that the support part 13 and the open side 122 enclose a rear cavity, which is also rectangular. The support portion 13 is distributed on the four sides of the accommodating cavity 11 and has a rectangular frame structure. The rear cavity is set according to the length and width of the rear cover 2 so that the rear cover 2 can be installed in the rear cavity and supported on the support portion 13. The sealing ring 3 can be installed between the support portion 13 and the rear cover 2. Therefore, the depth of the rear cavity should be equal to the sum of the thickness of the sealing ring 3 and the thickness of the rear cover 2 in the installed state, so that after the rear cover 2 is installed in the rear cavity, the outward side of the rear cover 2 is flush with the rear side of the plastic shell 1.
[0020] To ensure the sealing ring 3 is securely held between the support portion 13 and the rear cover 2, the support portion 13 includes a support portion 13 protruding along the inner wall of the accommodating cavity 11 for supporting the sealing ring 3, multiple first inner protruding portions 132 extending inward from the support portion 13 and spaced apart, and second inner protruding portions 133 extending inward from opposite sides of the support portion 13. The sealing ring 3 is shaped corresponding to the rear side of the support portion 13. The support portion 13 provides basic support for the sealing ring 3 and, in conjunction with the rear cover 2, forms a seal around the accommodating cavity 11, completing the basic seal. The first inner protruding portions 132 are distributed at different positions on the support portion 13 to increase the contact area between the sealing ring 3 and the rear cover 2, while also providing space on the support portion 13 for fixing the sealing ring 3 and the rear cover 2. This pulls on the sealing ring 3 to prevent it from deviating from the support portion 13, and to a certain extent, ensures that the sealing ring 3 does not deform. The second inner protrusion 133 is distributed on both sides of the support part 13, further increasing the contact area between the support part 13, the sealing ring 3 and the rear cover 2, and at the same time, completing the fixed connection between the rear cover 2 and the plastic shell 1.
[0021] In this embodiment, the width of the support portion 13 is uniform and smaller than the width of the first inner protrusion 132 and the second inner protrusion 133, so as to leave space for the receiving cavity 11. The first inner protrusions 132 are distributed at the four corners of the support portion 13 to strengthen the strength at the four corners and are distributed at the middle of the two long sides of the support portion 13, for a total of six first inner protrusions 132, but not limited to six, so that the sealing ring 3 and the rear cover 2 can be better pulled even from the longest side with the largest interval. For ease of installation, a first threaded hole 41 is provided along the length direction on each first inner protrusion 132. It should be noted that the side of the first inner protrusion 132 facing the receiving cavity 11 is arc-shaped for the purpose of setting the first inner protrusion 132, therefore, the width of the first inner protrusion 132 can also be the diameter of the corresponding arc. The second protruding portion 133 is located at the midpoint of the two sides of the support portion 13 along its length, that is, at the midpoint of the two wide sides of the support portion 13. The side of the second protruding portion 133 facing the accommodating cavity 11 is also arc-shaped and has a diameter. The diameter of the second protruding portion 133 is larger than the diameter of the first protruding portion 132, so that the second protruding portion 133 facilitates the installation of the plastic housing 1, the sealing ring 3, and the rear cover 2, while preventing the second protruding portion 133 from obstructing the conductive module. A second threaded hole 42 is provided on the second protruding portion 133, and the second threaded hole 42 extends along its length through the support portion 13 and the front side 121 of the plastic housing 1. On the front side 121 of the plastic housing 1, corresponding to the positions of the two second protruding portions 133, a relief groove 123 is recessed to shorten the depth of the second threaded hole 42, and also to provide installation space for the corresponding threaded structure.
[0022] To facilitate the installation of the communication module, a first boss 14 and a second boss 15 are provided within the accommodating cavity 11. The first boss 14 can be cylindrical and is axially arranged along the height direction of the plastic shell 1. A first insertion cavity 141 is formed on the first boss 14, extending through the first boss 14 in the height direction. The first insertion cavity 141 extends through the front side 121 of the plastic shell 1, and a ring protrusion 142 is formed on the front side 121 of the plastic shell 1 corresponding to the circumference of the first insertion cavity 141. A second insertion cavity 151 is formed on the second boss 15, recessed in the height direction. The second insertion cavity 151 extends through the front side 121 of the plastic shell 1 to form an insertion port 152. The height direction is defined as the insertion direction, and the communication module is installed in the first insertion cavity 141 and the second insertion cavity 151 along the insertion direction.
[0023] Please see Figures 3 to 6The rear cover 2 has a pressing portion 21 that protrudes along the height direction (or insertion direction) corresponding to the shape contours of the sealing ring 3 and the support portion 13. The shape and size of the pressing portion 21 are basically the same as the shape and size of the rear side of the support portion 13, and it is used to press the sealing ring 3 onto the support portion 13 when the rear cover 2 is installed. Therefore, the pressing portion 21 includes a main body portion 211 with the same shape as the support portion 13, a first protrusion 212 with the same shape as the first inner protrusion portion 132, and a second protrusion 213 with the same shape as the second inner protrusion portion 133. The first protrusion 212 also has a first threaded hole 41, and the second protrusion 213 also has a second threaded hole 42. The inner side of the pressing portion 21 encloses a space with the same shape as the receiving cavity 11, thereby raising the space of the receiving cavity 11 after the rear cover 2 is installed on the support portion 13. The thickness of the rear cover 2 is less than the depth of the rear cavity. Therefore, when the rear cover 2 is installed in the rear cavity, a gap is maintained between the rear cover 2 and the support part 13, thus forming a sealed cavity between the rear cover 2 and the support part 13 (or the rear cavity). To further improve the sealing effect of the sealing ring 3, a partition strip 22 is provided on the pressing part 21, which is distributed around the inner edge of the pressing part 21. The partition strip 22 is provided on the main body part 211, the first protrusion 212 and the second protrusion 213 on the side close to the inner space, and the first threaded hole 41 and the second threaded hole 42 on the rear cover 2 are both located on the periphery of the partition strip 22, so that after the rear cover 2 is pressed on the sealing ring 3, the partition strip 22 achieves air isolation by pressing it tightly against the sealing ring 3.
[0024] In order to initially position the sealing ring 3 on the support part 13 during the installation of the sealing ring 3 and before the installation of the rear cover 2, and to prevent the sealing ring 3 from moving, a positioning post 31 is provided on the front side of the outer ring part 32. The positioning post 31 can be distributed at the four corners to complete the four-corner positioning. The support part 13 is recessed with a positioning hole 134 for the positioning post 31 to be inserted into, so that the sealing ring 3 will squeeze the positioning post 31 into the positioning hole 134 during installation, thereby pulling the sealing ring 3 through the cooperation of the positioning post 31 and the positioning hole 134.
[0025] Please see Figures 3 to 6The sealing ring 3 is installed in the sealing cavity to press the sealing ring 3 against the support portion 13 after the rear cover 2 is installed in the rear cavity, thereby completing the sealing of the receiving cavity 11. The sealing ring 3 is configured to correspond to the shape and contour of the rear side of the support portion 13 and the pressing portion 21, and includes an outer ring portion 32 corresponding to the support portion 13, a first inner extension portion 33 corresponding to the first inner protrusion portion 132, and a second inner extension portion 34 corresponding to the second inner protrusion portion 133. The outer ring portion 32 is pressed against the support portion 13 by the main body portion 211 of the rear cover 2 to complete the basic support and sealing. The first inner extension portion 33 is pressed against the first inner protrusion portion 132 by the first protrusion portion 212 of the rear cover 2 to complete the tension limiting of the sealing ring 3. The second inner extension portion 34 is pressed against the second inner protrusion portion 133 by the second protrusion portion 213 of the rear cover 2 to complete the connection and fixation of the sealing ring 3, the plastic shell 1, and the rear cover 2. The first inner extension 33 is also provided with a first threaded hole 41. The first threaded holes 41 on the support part 13, the sealing ring 3 and the rear cover 2 are all fixed coaxially by screws. The second inner extension 34 is also provided with a second threaded hole 42. The second threaded holes 42 on the support part 13, the sealing ring 3 and the rear cover 2 are all fixed coaxially by bolts.
[0026] Please see Figures 1 to 3 , Figures 7 to 12 The conductive module includes a male connector 51, a first female connector 52, multiple second female connectors 53, multiple labels 54, and multiple sets of light guide pillars 55. The number of first insertion cavities 141 corresponds one-to-one with the number of male connectors 51, first female connectors 52, and second female connectors 53. For example, when there are eight second female connectors 53, there are ten first bosses 14 and ten first insertion cavities 141. For ease of arrangement, the male connectors 51, first female connectors 52, and second female connectors 53 are arranged in a rectangular array. Therefore, the first bosses 14 are arranged in a rectangular array. In one embodiment, the male connectors 51, first female connectors 52, and second female connectors 53 can be arranged in five rows and two columns, with one column containing one male connector 51 and four second female connectors 53, and the other column containing one female connector and four second female connectors 53, with the male connectors 51 and first female connectors 52 located in the same row. Therefore, the male connector 51, the first female connector 52 and the eight second female connectors 53 are each individually inserted into each first insertion cavity 141, that is, only one male connector 51, the first female connector 52 or the second female connector 53 is inserted into each first insertion cavity 141.
[0027] In this embodiment, the male connector 51, the first female connector 52, and the second female connector 53 all include a plastic housing and conductive terminals inserted into the housing. The housing includes a cylindrical insertion portion, a limiting portion coaxially connected to the insertion portion and having a diameter larger than the insertion portion, and a surrounding portion with a diameter smaller than the limiting portion. The insertion portion of the male connector 51 is configured as the first insertion portion 511, the insertion portion of the first female connector 52 is configured as the second insertion portion 521, and the insertion portion of the second female connector 53 is configured as the third insertion portion 531. The first insertion portion 511 is hollow inside and has a first pair of through-cavities 512 forming therein. The conductive terminals of the male connector 51 pass through the limiting portion and into the first pair of through-cavities 512, and a mating space is left between the conductive terminals of the male connector 51 and the first pair of through-cavities 512. When the male connector 51 is inserted into the first insertion cavity 141, the limiting part restricts the insertion depth, and the first insertion part 511 protrudes forward from the first insertion cavity 141, thereby forming a male interface 513 on the front side 121 of the plastic housing 1. To facilitate a stable connection between the male interface 513 and the complementary connector, an external thread is provided on the outer wall of the male interface 513, i.e., the first insertion part 511. The second insertion part 521 has a second pair of insertion cavities 522 corresponding to the position and number of conductive terminals, and the second pair of insertion cavities 522 extend forward through the second insertion part 521. The conductive terminals of the first female connector 52 are exposed in the second pair of cavities 522 after passing through the limiting part. When the first female connector 52 is inserted into the first insertion cavity 141, the limiting part restricts the insertion depth. The second insertion part 521 extends out of the first insertion cavity 141 and is located inside the annular protrusion 142. The diameter of the second insertion part 521 is smaller than the diameter of the annular protrusion 142, so that a mating space is formed between the annular protrusion 142 and the outer wall of the second insertion part 521, thereby forming the first female interface 523 on the front side 121 of the plastic housing 1. In order to facilitate a stable connection between the first female interface 523 and the complementary connector, an internal thread is provided on the inner wall of the first insertion cavity 141. The complementary connector is inserted into it and makes contact with the conductive terminals in the second pair of cavities 522. A foolproof groove can be formed on the outer wall of the second insertion part 521.
[0028] The third insertion portion 531 has a third pair of insertion cavities 532 corresponding to the position and number of conductive terminals. The third pair of insertion cavities 532 extend forward through the third insertion portion 531. The conductive terminals of the second female connector 53 are exposed in the third pair of insertion cavities 532 after passing through the limiting portion. When the second female connector 53 is inserted into the first insertion cavity 141, the limiting portion restricts the insertion depth. The third insertion portion 531 extends out of the first insertion cavity 141 and is located inside the annular protrusion 142. The diameter of the third insertion portion 531 is smaller than the diameter of the annular protrusion 142, so that a mating space is formed between the annular protrusion 142 and the outer wall of the third insertion portion 531, thereby forming the second female interface 533 on the front side 121 of the plastic housing 1. In order to facilitate a stable connection between the second female interface 533 and the complementary connector, an internal thread is also provided on the inner wall of the corresponding first insertion cavity 141. The complementary connector is inserted into it and mats with the conductive terminals in the third pair of insertion cavities 532 to conduct electricity. Alternatively, a foolproof groove can be formed on the outer wall of the third connector 531. Therefore, the male connector 513, the first female connector 523, and each of the second female connectors 533 are arranged in a rectangular array on the front side 121 of the plastic housing 1. The number of first protrusions 14 corresponds to the number and position of the male connector 51, the first female connector 52, and the second female connector 53. Each first protrusion 14 is integrally connected to the support portion 13 to enhance strength.
[0029] A label 54 is provided between each pair of adjacent second female interfaces 533 in each column, and between the male interface 513 and the adjacent second female interface 533 along the column direction, for identification purposes. A mating groove 16 is recessed on the front side 121 of the plastic housing 1 at the position corresponding to the label 54, and the label 54 is installed within the mating groove 16. Multiple protrusions 161 are provided within the mating groove 16. The protrusions 161 can be four in total, arranged in a rectangular array, with a spacer cavity formed between them. A locking block 541 protrudes from the label 54 corresponding to the spacer cavity to engage with it, thereby increasing the bonding force between the label 54 and the mating groove 16.
[0030] Between each pair of adjacent second female terminals 533 in each row, there are multiple light guide pillars 55 arranged in an array. There can be two or four light guide pillars 55. Each light guide pillar 55 corresponds to a socket 152. The light guide pillar 55 passes through the second insertion cavity 151 and enters the socket 152. The light guide pillars 55 are made of transparent material to guide the light source on the circuit board to the front side 121 of the plastic housing 1 for signal indication.
[0031] The working method of one embodiment of the wiring module connector of this utility model is as follows: After the positioning post 31 of the sealing ring 3 is squeezed into the positioning groove so that the sealing ring 3 overlaps with the support part 13, the rear cover 2 is inserted into the rear cavity so that the pressing part 21 overlaps with the sealing ring 3. Then, screws are screwed into the first threaded hole 41 and bolts are screwed into the second threaded hole 42 to fix the post rear cover 2 and the sealing ring 3. After the partition strip 22 abuts against the sealing ring 3 to complete the seal, the complementary connector is inserted into the corresponding male connector 51, the first female connector 52 and the second female connector 53 to achieve conduction.
[0032] Compared with the prior art, the wiring module connector of this utility model, while completing basic waterproofing and sealing, improves the limiting of the sealing ring 3, increases the pulling and positioning of the sealing ring 3, reduces the possibility of displacement and deformation of the sealing ring 3, and improves the overall stability and reliability.
