Detailed Implementation
[0021] Please see Figures 1-4 In this embodiment of the present invention, a high-sealing waterproof aviation connector includes a first anti-mistake connector body 10 and a second anti-mistake connector body 11. The first anti-mistake connector body 10 includes a first anti-mistake base 3 installed in a sealing colloid. A first anti-mistake connector rear cover 1 is installed on the outer surface of the first anti-mistake base 3. Insertion female pin terminals 2 are inserted into the first anti-mistake base 3 and the first anti-mistake connector rear cover 1. A zinc alloy nut 4 is provided on the outside of the first anti-mistake base 3. The second anti-mistake connector body 11 includes a second anti-mistake connector zinc alloy nut 4. The outer thread of the zinc alloy threaded base 5 of the second foolproof connector is connected to a zinc alloy nut 6. The inner part of the zinc alloy threaded base 5 of the second foolproof connector is provided with a second foolproof head base 7 and a second foolproof connector back cover 9. Several male pins are inserted between the second foolproof head base 7 and the second foolproof connector back cover 9 to achieve precise docking and connection between the female pin terminal 2 inserted inside the first foolproof connector and the male pin terminal 8 inserted inside the second foolproof zinc alloy base. The terminals are not protected against bending or breakage.
[0022] Furthermore, such as Figure 2 Figure 3As shown, the rear cover 1 of the first foolproof connector of the plug-in block is provided with two locking feet. In order to secure the first foolproof base 3 of the plug-in block and prevent it from falling off or leaking glue during assembly and secondary gluing, which could cause displacement of the built-in adapter terminals and short circuits due to glue leakage, the rear cover 1 of the first foolproof connector of the plug-in block has multiple flat-row adapter insertion female pin terminals 2 insertion guide fixing holes inside. One end face of each hole is an open isolation opening, which allows for quick, effective and intuitive soldering connection of the cable and the female pin terminal 2. The flat-row open isolation opening eliminates the need to rotate to find the terminal head for soldering during the soldering process, thereby reducing a lot of the effort and time of employees to solder. The first foolproof base 3 has a foolproof groove, a zinc alloy nut 4 fixing and limiting boss, a rubber-coated clip groove, and an insertion clip opening groove for the first foolproof connector rear cover 1 of the block to be inserted. One end face of the base has a foolproof boss at the connection point with the first foolproof connector rear cover 1 of the block to be inserted. Inside, there is a foolproof square-to-circular insertion hole for the female pin terminal 2. The foolproof groove is used for precise mating connection with the second foolproof connector zinc alloy threaded base 5. The zinc alloy nut 4 fixing and limiting function prevents the zinc alloy nut 4 from falling off or loosening when connected to the second foolproof connector zinc alloy threaded base 5. The rubber-coated clip groove is used to secure the cable during secondary rubber coating, preventing the rubber and cable from being pulled out. The internal foolproof square-to-circular insertion hole for the female pin terminal 2 is designed for easy and precise insertion, facilitating orientation and preventing the female pin terminal 2 from rotating in an inconsistent direction, thus avoiding defects and loss of foolproof function. The first anti-foolproof connector rear cover 1 is inserted into the slot of the locking pin to ensure that the first anti-foolproof connector rear cover 1 is inserted and locked tightly, so that no glue leakage occurs during the secondary gluing, and the glue flows into the slot of the insertion female pin terminal 2, causing a short circuit. One end face of the first anti-foolproof connector rear cover 1 connected to the block to be inserted is provided with an anti-foolproof protrusion, so that the block to be inserted will not be installed in the wrong direction when the first anti-foolproof connector rear cover 1 is installed on the first anti-foolproof base plug, and it can also be rotated after installation, so as to achieve the anti-foolproof function.
[0023] Furthermore, such as Figure 2 and Figure 3As shown, the first anti-mistake base 3 of the insert block has an outer periphery including an anti-mistake groove, a zinc alloy nut 4 fixing and limiting boss, a rubber-coated clip groove, and an insertion clip opening groove for the first anti-mistake connector rear cover 1 of the insert block. One end face has an anti-mistake boss at the connection point with the first anti-mistake connector rear cover 1 of the insert block, and an anti-mistake square-to-circular insertion female pin terminal 2 insertion hole. The anti-mistake groove is used for precise mating connection with the second anti-mistake connector zinc alloy threaded base 5. The zinc alloy nut 4 fixing and limiting function prevents the zinc alloy nut 4 from falling off or loosening when connected to the second anti-mistake connector zinc alloy threaded base 5. The rubber-coated clip groove is used to prevent the rubber and cable from being pulled out during secondary rubber coating, thus achieving a fixing function. The internal anti-mistake square-to-circular insertion female pin terminal 2 hole design facilitates precise insertion and directional placement, preventing the insertion female pin terminal 2 from rotating in an inconsistent direction, thus avoiding defects and loss of anti-mistake effect. The first anti-foolproof connector rear cover 1 is inserted into the slot of the locking pin to ensure that the first anti-foolproof connector rear cover 1 is inserted and locked tightly, so that no glue leakage occurs during the secondary gluing, and the glue flows into the slot of the insertion female pin terminal 2, causing a short circuit. One end face of the first anti-foolproof connector rear cover 1 connected to the block to be inserted is provided with an anti-foolproof protrusion, so that the block to be inserted will not be installed in the wrong direction when the first anti-foolproof connector rear cover 1 is installed on the first anti-foolproof base plug, and it can also be rotated after installation, so as to achieve the anti-foolproof function.
[0024] Furthermore, such as Figure 2 and Figure 3 As shown, the second anti-foolproof head base 7 of the insert block has an anti-foolproof flat edge at one end of its outer perimeter. Inside, there are multiple anti-foolproof square insertion holes for male pin terminals 8, a groove for the anti-foolproof second anti-foolproof connector rear cover 9, and a protrusion for the second anti-foolproof connector rear cover 9. The anti-foolproof flat edge of the second anti-foolproof head base 7 is designed to ensure accurate orientation when inserting into the zinc alloy threaded base 5 of the second anti-foolproof connector, preventing rotation and thus preventing foolproofing. The multiple anti-foolproof square terminal insertion holes are used to insert the male pin terminals 8, ensuring that the direction of insertion is determined and that the inserted male pin terminals 8 will not rotate or shift when properly inserted. The groove and protrusion of the anti-foolproof second anti-foolproof connector rear cover 9 are designed to prevent incorrect orientation when inserting and to ensure that the anti-foolproof second anti-foolproof connector rear cover 9 is securely locked, thus providing a foolproof function. To prevent detachment or glue leakage during assembly and secondary coating, which could lead to displacement of the built-in adapter terminals and short circuits due to glue ingress or egress,
[0025] Furthermore, such as Figure 2 and Figure 3As shown, the rear cover 9 of the second anti-foolproof connector of the plug-in block has an anti-foolproof groove on its periphery. The rear cover 9 of the second anti-foolproof connector of the plug-in block has multiple flat-row adapter insertion male pin terminal 8 insertion guide fixing holes inside. One end face of the hole is an open isolation opening, which is used for the cable and the insertion male pin terminal 8 to quickly, effectively and intuitively solder connection. The flat-row open isolation opening does not require rotating to find the terminal head for soldering during the soldering process, thereby reducing a lot of the effort and time of employees to solder.
[0026] Furthermore, such as Figure 2 and Figure 3 As shown, the zinc alloy threaded base 5 of the second anti-mistake connector has threads on both ends of its outer periphery, a circular fixing boss in the middle of its outer periphery, and multiple anti-mistake bosses inside. The threads on the outer periphery of the zinc alloy threaded base 5 of the second anti-mistake connector are for rotating and fixing with the zinc alloy nuts 4 that are fitted on the outer sleeve of the first anti-mistake connector base 3, preventing the first and second anti-mistake connectors from falling off. The anti-mistake bosses inside are for accurately confirming the direction of installation when the second anti-mistake connector base 7 is inserted, and for accurately guiding the insertion of the first anti-mistake connector base 3, so that the terminals are accurately connected. It also protects the terminals from bending or breaking.
[0027] Furthermore, such as Figure 2 , Figure 3 The second foolproof connector shown is equipped with a zinc alloy nut 6, which is used to fasten the object to be installed when one end of the zinc alloy threaded base 5 of the second foolproof connector is not used for secondary insulated cable connection.
[0028] Furthermore, to ensure that the second foolproof connector base 7 and the second foolproof connector rear cover 9 inside the second foolproof connector do not fall off and exit from the zinc alloy threaded base 5 of the second foolproof connector, a riveting process needs to be performed on one end face of the second foolproof connector base 7 and the second foolproof connector rear cover 9 to prevent them from falling off and exiting.
[0029] like Figure 4 This article illustrates the key design considerations for automated insertion accessories and terminals, including the definitions of male and female pins, braided wires, and ground wires in cables. We design the braided wire ground wire in the slots of the first and second foolproof connector back covers 2 and 4, enabling universal compatibility.
[0030] like Figure 4The key design features of the first foolproof connector back cover 1 shown are: fastening feet on both ends for securing the first foolproof base 3; a foolproof mounting groove on its main body; vertical parallel bosses on its main body plane for automatic machine selection of sides and surfaces; an insertion slot for the female pin terminal 2; and markings 2.3.1.4 on its main body plane for identifying the ground wire position by soldering the insertion female pin terminal 2.
[0031] like Figure 4 The key design features of the insertion terminal 2 shown are as follows: the cylindrical part transitions to a square part, the square part extends from the plane of the through hole to a flat, obliquely shaped surface, and then transitions to a flat square that bends upwards at a 90-degree angle (this surface is for soldering). One end of the cylindrical part has multiple recessed clamping strips (used to clamp the inserted male pin terminal 8). The square part serves to fix the pin's direction during automated insertion, preventing rotation and foolproofing.
[0032] like Figure 4 The key design features of the first foolproof base 3 shown are: its outer periphery includes a foolproof groove, a zinc alloy nut fixing and limiting boss, a rubber-coated clip groove, and an insertion slot for the back cover 1 of the block to be inserted. One end face has a foolproof boss at its connection with the back cover 1 of the block to be inserted, and inside is a foolproof square-to-circular insertion hole for the female pin terminal 2. The foolproof groove ensures precise mating with the second foolproof connector zinc alloy threaded base 5. The zinc alloy nut fixing and limiting mechanism prevents the zinc alloy nut from falling off or loosening during connection. The rubber-coated clip groove secures the cable during secondary rubber coating, preventing the rubber and cable from being pulled out. The internal square-to-circular insertion hole for the female pin terminal 2 facilitates precise insertion and orientation, preventing inconsistent rotation of the female pin terminal 2, thus avoiding defects and loss of foolproof protection. The recessed slot of the rear cover 1 is designed to ensure a tight and secure insertion, preventing glue leakage during secondary coating and preventing glue from flowing into the slot of the insertion pin terminal 2, which could cause a short circuit. One end face of the rear cover 1, where it connects to the block to be inserted, has a foolproof protrusion. This prevents the rear cover 1 from being installed in the first foolproof base plug in the wrong direction, while also allowing it to rotate properly after installation, thus achieving a foolproof function. The shape of the secondary coating slot's bearing surface allows it to be used for edge / surface selection and foolproofing during automation.
[0033] like Figure 4The second anti-mistake base 7 shown has an anti-mistake flat edge at one end of its outer perimeter. Inside, it has multiple anti-mistake square insertion holes for male pin terminals 8, a groove for the anti-mistake base cover 9, and a protrusion for the anti-mistake base cover 9. The anti-mistake flat edge of the anti-mistake base 7 ensures accurate orientation when inserted into the second anti-mistake zinc alloy threaded base 5, preventing rotation and thus preventing mistaken insertion. The multiple anti-mistake square terminal insertion holes ensure the correct orientation of the male pin terminals 8 during insertion, preventing rotation and displacement. The groove and protrusion of the anti-mistake base cover 9 prevent incorrect orientation during insertion and ensure the cover is securely locked, providing a secure anti-mistake function. This prevents detachment and glue leakage during assembly and secondary gluing, which could lead to displacement of the built-in adapter terminals and short circuits due to glue leakage. The anti-mistake planar shape at one end allows for edge / surface selection during automation.
[0034] like Figure 4 The design of the inserted male pin terminal 8, as shown, features a transition from a cylindrical through-hole to a square through-hole. The square through-hole extends to a flat, obliquely shaped surface, then transitions to a flat, upwardly obliquely bent square (this surface is for soldering). One end of the cylindrical portion is rounded (for easy insertion of the female pin). The square portion serves to fix the pin's direction during automated insertion, preventing rotation and misalignment.
[0035] like Figure 4 The back cover 9 of the anti-foolproof base shown has an anti-foolproof groove on its outer periphery. The back cover 9 of the block to be inserted has multiple flat-row adapter insertion male pin terminals 8 insertion guide fixing holes inside. One end face of the hole is an open isolation opening, which is used for the cable braid and the insertion male pin terminal 8 to quickly, effectively and intuitively solder connection. Its flat-row open isolation opening can realize automated soldering during the soldering process. There is no need to rotate to find the terminal head for soldering, thus reducing a lot of labor and time for employees to solder. Its main body plane has braided wire solder connection terminal (female pin) identification number 2.3.1.4, which is used to identify the ground wire position.
