Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connection technology, specifically to an electrical connector that allows for intuitive judgment of whether it is properly inserted. Background Technology
[0002] With the rapid development of communication technology and the continuous improvement of industrial automation, modern equipment has placed more stringent requirements on the reliability of electrical connectors during insertion and removal. As a bridge for current and signal transmission between devices, the stability of the electrical connector's insertion state directly affects the normal operation and performance of the equipment.
[0003] However, existing electrical connectors have certain limitations. For example, when the male and female terminals are being plugged in, operators often find it difficult to visually determine whether the male terminal is fully inserted. This uncertainty introduces several potential risks. Since electrical connectors carry the transmission of current and / or signals, improper insertion can lead to poor contact between the male and female terminals. This poor contact can not only result in poor current transmission but also cause signal interruption or distortion, thus affecting the normal operation of the entire device.
[0004] Therefore, those skilled in the art urgently need to develop an electrical connector that can intuitively determine whether it is properly inserted. Utility Model Content
[0005] The purpose of this invention is to address the problems mentioned in the background art by providing an electrical connector that allows for intuitive judgment of whether it is properly inserted. This connector has a clear and unambiguous insertion indication signal, enabling operators to immediately determine whether the male and female terminals are fully engaged. By ensuring proper insertion of the electrical connector, the risks associated with poor contact are effectively eliminated, thereby guaranteeing the normal operation of the equipment.
[0006] To achieve the above objectives, this utility model provides an electrical connector that allows for intuitive judgment of whether it is fully inserted. The electrical connector includes a male end and a female end that is inserted into the male end. The female end includes a female shell with a cavity. The male end includes a male shell, and the protrusion of the male shell can be inserted into the cavity.
[0007] The male end also includes a positioning indicator ring fitted on the rear end of the outer wall of the male shell boss. The positioning indicator ring is a different color from the male shell. Under the action of external force, the positioning indicator ring can undergo elastic deformation along with the boss and insert into the cavity. If the positioning indicator ring is fully inserted into the cavity and cannot be seen, then the male end and the female end are in place.
[0008] In one possible implementation, under the action of external force, the positioning indicator ring is pulled out of the cavity along with the boss. When the positioning indicator ring is seen, the male end and the female end are not fully inserted.
[0009] In one possible implementation, an indicator groove is provided at the rear end of the outer wall of the boss, and the positioning indicator ring is fitted into the indicator groove;
[0010] If the depth of the indicator groove is less than the thickness of the positioning indicator ring, then the positioning indicator ring is higher than the boss. When the positioning indicator ring is inserted into the cavity along with the boss, the positioning indicator ring will undergo elastic deformation.
[0011] If the depth of the indicator groove is greater than or equal to the thickness of the positioning indicator ring, and the positioning indicator ring is not higher than the boss, the positioning indicator ring will not undergo elastic deformation when it is inserted into the cavity along with the boss.
[0012] In one possible implementation, the positioning indicator ring is red, and the male shell and the female shell are the same color and both are black.
[0013] In one possible implementation, the boss has a power supply hole and a signal hole, the number of power supply holes is at least one, and a first power supply terminal is inserted into the power supply hole; the number of signal holes is at least one, and a first signal terminal is inserted into the signal hole.
[0014] In one possible implementation, the cavity is provided with a power post that plugs into the power port and a signal post that plugs into the signal port. Each power post is covered with a second power terminal, which is plugged into the first power terminal. Each signal post is covered with a second signal terminal, which is plugged into the first signal terminal.
[0015] In one possible implementation, the second power terminal is provided with a crown spring, which has a “)(” structure and the openings on both sides are recessed in the middle and are press-fitted to the head of the first power terminal.
[0016] In one possible implementation, the second signal terminal has a pointed conical section, and the pointed conical section has a cross-shaped through groove for interference fit with the first signal terminal rod section.
[0017] In one possible implementation, the male end further includes a first wire and a first sheath, wherein the first wire is soldered to the tail ends of the first power terminal and the first signal terminal;
[0018] The first protective shell, the male shell, and the first wire are injection molded together as one unit.
[0019] In one possible implementation, the female end further includes a second wire and a second sheath, the second wire being soldered to the tail ends of the second power terminal and the second signal terminal;
[0020] The second protective shell, the mother shell, and the first wire are injection molded together as one unit.
[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0022] This invention provides an electrical connector that allows for intuitive judgment of whether the connector is properly inserted. The connector includes a male end and a female end. The female end includes a female shell, and the male end includes a male shell and a positioning indicator ring. A boss on the male shell can be inserted into a recess in the female shell. The positioning indicator ring is fitted onto the rear end of the boss on the male shell. The positioning indicator ring is a different color from the male shell. Under external force, the positioning indicator ring, along with the boss, is inserted into the recess. When the red positioning indicator ring is fully inserted into the black recess, a clear visual signal is formed, allowing the operator to quickly and accurately determine the insertion status of the male and female ends. Simultaneously, the positioning indicator ring not only eliminates the risk of poor contact but also improves the waterproof performance of the electrical connector. Attached Figure Description

[0031] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0032] To address the problems in the background art, this utility model provides an electrical connector that allows for intuitive judgment of whether it is fully inserted. The connector includes a male end and a female end that plugs into the male end, as detailed below:
[0033] 1-Pale end
[0034] The male end includes a male shell, and the boss of the male shell can be inserted into the cavity;
[0035] The male end also includes a positioning indicator ring fitted on the rear end of the outer wall of the male shell boss. The color of the positioning indicator ring is different from that of the male shell. Under the action of external force, the positioning indicator ring can undergo elastic deformation with the boss and be inserted into the cavity, and the positioning indicator ring cannot be seen. When the positioning indicator ring is fully inserted into the cavity, the male end and the female end are inserted into the cavity.
[0036] Under the action of external force, the positioning indicator ring is pulled out of the cavity along with the boss. When the positioning indicator ring is seen, it means that the male end and the female end are not inserted into the correct position.
[0037] In specific application scenarios, the positioning indicator ring not only provides an intuitive indication of the electrical connector's insertion position, but also enhances the connector's waterproof performance, providing strong support for the reliable operation of the equipment.
[0038] The positioning indicator ring provides a visual signal to indicate whether the male and female ends are fully inserted. When the positioning indicator ring is fully inserted into the cavity of the female end, the operator can immediately know that the insertion operation is complete.
[0039] In summary, by observing whether the position indicator ring is fully inserted into the cavity, the insertion status of the male and female terminals can be directly judged, which can effectively avoid the risk of poor contact and interruption of current / signal transmission caused by improper insertion, and improve the reliability and stability of the equipment.
[0040] In some examples, an indicator groove is provided at the rear end of the outer wall of the boss, and the positioning indicator ring is fitted into the indicator groove.
[0041] In specific application scenarios, the indicator groove is opened on the rear end of the outer wall of the male end boss, located in the key area where the male end and the female end are inserted.
[0042] The indicator groove is specifically a recess or groove, and its shape and size are able to fit or fix the positioning indicator ring. By fitting it in the indicator groove, the positioning indicator ring is firmly installed on the boss, effectively preventing it from falling off or shifting during the insertion process.
[0043] The combination of the indicator groove and the positioning indicator ring improves the reliability of the electrical connector. By ensuring the stable installation and accurate guidance of the positioning indicator ring, operators can more easily determine the mating status of the male and female ends, thereby reducing the risk of poor contact due to improper mating.
[0044] If the depth of the indicator groove is less than the thickness of the positioning indicator ring, the positioning indicator ring will be higher than the boss. When the positioning indicator ring is inserted into the cavity along with the boss, the positioning indicator ring will undergo elastic deformation.
[0045] In specific applications, the positioning indicator ring needs to be made of a flexible material to ensure that it can deform under external force and return to its original shape. At the same time, since the positioning indicator ring is subjected to friction and compression during insertion, it also needs to have good wear resistance to extend its service life.
[0046] If the depth of the indicator groove is greater than or equal to the thickness of the positioning indicator ring, and the positioning indicator ring is not higher than the boss, the positioning indicator ring will not undergo elastic deformation when it is inserted into the cavity along with the boss. This allows the positioning indicator ring to be inserted into the cavity along with the boss at the male end under the action of external force, thus ensuring the smoothness of the male and female end insertion process.
[0047] In some examples, the male end also includes a waterproof ring located in front of the positioning indicator ring, and its retainer is attached to the boss.
[0048] In specific application scenarios, the outer wall of the boss is also provided with a waterproof groove, and a waterproof ring is fitted inside the waterproof groove. The waterproof ring effectively prevents moisture and foreign objects from entering the electrical connector, improves the waterproof and dustproof rating of the equipment, ensures the sealing performance of the electrical connector in harsh environments, and prevents moisture and foreign objects from entering and affecting the connector performance.
[0049] In some examples, the position indicator circle is red, and the male and female shells are the same color and both are black.
[0050] In specific application scenarios, the position indicator ring is a different color from the male and female shells to provide operators with an intuitive visual comparison. During the insertion process, operators can quickly determine whether the male and female terminals are fully inserted by using the color difference.
[0051] Those skilled in the art will understand that red, as a bright and eye-catching color, has a strong visual appeal. Choosing red as the color of the position indicator ring ensures that operators can clearly see the status of the indicator ring under various lighting conditions.
[0052] Furthermore, red is considered an important color for warnings or instructions in many cultures. In electrical connectors, red is used as a clear indication of "in position," similar to how red in traffic lights signifies "stop" or "caution." At the same time, the red position indicator ring provides a striking contrast against the black male and female housings. This black and red color combination is not only aesthetically pleasing but also significantly improves operational accuracy and efficiency.
[0053] The position indicator ring can be red or other colors, provided that it does not match the color of the male and female shells. As long as the working performance of the electrical connector is not affected, those skilled in the art can choose the color of the position indicator ring according to actual needs. Changes in the color of the position indicator ring do not affect the scope of protection of this application.
[0054] In some examples, the boss has a power hole and a signal hole, with at least one power hole and a first power terminal inserted in the power hole, and at least one signal hole and a first signal terminal inserted in the signal hole.
[0055] In specific application scenarios, there are three power ports arranged in a triangular shape; there are six signal ports arranged in a Y-shape.
[0056] In specific application scenarios, the power hole is an irregular circular hole. The power hole includes a first power hole and a second power hole. The second power hole is located below the first power hole, and there are two second power holes placed symmetrically to the left and right sides at the center of the first power hole. The second power hole has a second protrusion with a circular top opening upward.
[0057] The signal hole is a standard round hole, and the diameter of the signal hole is smaller than that of the power hole.
[0058] Furthermore, the triangular arrangement of power ports and the Y-shaped distribution of signal ports are matched in shape and position to ensure a unique correct insertion direction, completely eliminating the risk of reverse or incorrect insertion, avoiding damage or scrapping of electrical connectors, and improving equipment safety and service life.
[0059] In some examples, the male end also includes a first wire and a first sheath, the first wire being soldered to the tail ends of the first power terminal and the first signal terminal;
[0060] The first protective shell, the male shell, and the first wire are injection molded together as one unit.
[0061] In specific application scenarios, the first wire serves as the transmission medium for current and / or signals. In electrical connectors, the first power terminal and the first signal terminal are responsible for the specific electrical connections, while the first wire acts as a bridge between these terminals and external devices, ensuring smooth transmission of current and signals.
[0062] The first wire is securely connected to the ends of the power and signal terminals via soldering, ensuring the stability and reliability of the electrical connection. This connection method effectively prevents poor contact or open circuits caused by external factors such as vibration and impact.
[0063] Meanwhile, the first wire is soldered to the tail ends of the power and signal terminals, which facilitates production and assembly.
[0064] The first wire has excellent conductivity, ensuring efficient transmission of current and signals. Typically, the first wire is made of metals with superior conductivity, such as copper or aluminum.
[0065] Furthermore, the first sheath is an integral part of the male end of the electrical connector, and it is injection molded together with the male housing and the first wire to form a single integrated structure. Since the first sheath is located outside the male end, covering the rear end of the male housing and the connection point of the first wire, it protects the male housing and the first wire from damage by the external environment and prevents the first wire from detaching or being damaged by external forces during insertion or use, thus ensuring the stability of the electrical connection.
[0066] The first housing is injection molded to be tightly bonded to the male housing and the first wire, forming a robust integral structure that enhances the mechanical strength of the electrical connector.
[0067] 2-Mother end
[0068] The female end includes a female shell, and a cavity is formed on the female shell.
[0069] In some examples, the cavity is provided with a power post that plugs into the power port and a signal post that plugs into the signal port. Each power post is covered with a second power terminal, which is plugged into the first power terminal. Each signal post is covered with a second signal terminal, which is plugged into the first signal terminal.
[0070] In specific application scenarios, the shapes of the power pillars and the power holes are adapted to each other and their positions correspond one-to-one.
[0071] The power supply pins and signal holes are shaped and positioned to match each other.
[0072] In some examples, the second power terminal has a crown spring with a “)(” structure, and the center of the openings on both sides is recessed to allow for an interference fit with the head of the first power terminal. The second signal terminal has a pointed conical section with a cross-shaped through groove for interference fit with the rod section of the first signal terminal.
[0073] In specific application scenarios, the second power terminal within the power supply column is equipped with a crown spring structure, and the second signal terminal within the signal column is equipped with a pointed conical section and a cross-shaped through slot to enhance the contact reliability and signal transmission stability between the terminals. Furthermore, this ensures correct terminal mating and avoids poor contact or signal interference.
[0074] In some examples, the female end also includes a second wire and a second sheath, the second wire being soldered to the tail end of the second power terminal and the second signal terminal;
[0075] The second protective shell, the main shell, and the first wire are injection molded together as one unit.
[0076] In specific application scenarios, since the second wire has the same function and role as the first wire, and the second sheath has the same function and role as the first sheath, this application will not elaborate further on the second wire and the second sheath. Example 1
[0077] Based on the above concept, such as Figure 1-6 As shown in the figure, this embodiment provides an electrical connector for a specific application scenario, such as... Figure 2 As shown, the electrical connector includes a male end 1 and a female end 2 that plugs into the male end 1, as...

The male end 1 includes a male shell 11, and the boss 111 of the male shell 11 can be inserted into the cavity 211.
[0078] Among them, such as Figure 3 As shown, the male end 1 also includes a positioning indicator ring 12 that is fitted onto the rear end of the outer wall of the male shell 11 boss 111. The color of the positioning indicator ring 12 is different from the color of the male shell 11. Under the action of external force, the positioning indicator ring 12 can undergo elastic deformation with the boss 111 and be inserted into the cavity 211, and the positioning indicator ring 12 is not visible. When the positioning indicator ring 12 is fully inserted into the cavity 211, the male end 1 and the female end 2 are inserted into position.
[0079] In the example, under the action of external force, the positioning indicator ring 12 is pulled out of the cavity 211 along with the boss 111. When the positioning indicator ring 12 is seen, the male end 1 and the female end 2 are not inserted into the correct position.

[0081] If the depth of the indicator groove 1111 is equal to the thickness of the positioning indicator ring 12, the positioning indicator ring 12 is not higher than the boss 111, and the positioning indicator ring 12 does not undergo elastic deformation when it is inserted into the cavity 211 along with the boss 111.
[0082] In this example, the position indicator ring 12 is red, and the male shell 11 and female shell 21 are the same color and both are black.
[0083] In an example, such as Figure 4 As shown, the boss 111 has a power supply hole 112 and a signal hole 113.

Each power post 212 is covered with a second power terminal 214, which is inserted into the first power terminal 114. Each signal post 213 is covered with a second signal terminal 215, which is inserted into the first signal terminal 115.
[0085] In an example, such as Figure 1 As shown, a crown spring 216 is provided inside the second power terminal 214. The crown spring 216 has a “” structure, and the middle of the openings on both sides is recessed and is interference-fitted with the head of the first power terminal 114.
[0086] In an example, such as Figure 1 As shown, the second signal terminal 215 has a pointed cone section, and a cross-shaped through groove is provided on the pointed cone section for interference fit with the rod section of the first signal terminal 115.
[0087] In an example, such as Figure 3 As shown, the male end 1 also includes a waterproof ring 14, which is located in front of the positioning indicator ring 12 and is fitted onto the boss 111. Example 2
[0088] Based on Example 1, such as Figure 1 As shown, the male end 1 also includes a first wire and a first sheath 13, with the first wire soldered to the tail ends of the first power terminal 114 and the first signal terminal 115;
[0089] The first protective shell 13, the male shell 11, and the first wire are injection molded together as one unit.
[0090] In an example, such as Figure 1 As shown, the female end 2 also includes a second wire and a second protective shell 22, and the second wire is welded to the tail end of the second power terminal 214 and the second signal terminal 215;
[0091] The second protective shell 22, the mother shell 21, and the first wire are injection molded together as one unit.
