[0041] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present at the same time. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component present at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "rear", and similar expressions used in this article are only for illustrative purposes.

[0042] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0043] Please refer to Figures 1-7 , an embodiment of the present application provides a structure 100 for preventing the wire skin from retreating during the injection molding process of a signal connector, which uses injection molding liquid for injection molding. The structure includes: a signal wire 10 and a pressing member 20. Before injection molding, the signal wire 10 is placed in the cooling cavity of the injection mold. The signal wire 10 includes: a wire skin 11 and a wire core 12 disposed inside the wire skin 11; before injection molding, the pressing member 20 is sleeved on the wire skin 11 along the axial direction F1. The pressing member 20 is located at one end of the wire skin 11 away from the wire core 12, and the pressing member 20 presses the wire skin 11 and the wire core 12 along the longitudinal direction F2.

[0044] Specifically, the signal wire 10 is a core component of the signal connector 200. The wire skin 11 is used for insulation and protection of the wire core 12, and the wire core 12 is used for transmitting electrical signals. In order to maintain the stability of the signal wire 10 during the injection molding process, it needs to be correctly placed in the cooling cavity of the mold.

[0045] The pressing member 20 is used to prevent the wire skin 11 of the signal wire 10 from sliding or the wire skin 11 from falling off due to liquid pressure during the injection molding process. Through the axial sleeve connection along the direction F1 and the longitudinal pressing along the direction F2, the pressing member 20 provides an additional mechanical fixing force to ensure the stable positions of the wire skin 11 and the wire core 12 during the injection molding process.

[0046] Select a suitable material to manufacture the pressing member 20 to ensure that its inner diameter matches the outer diameter of the wire skin 11 and its length is appropriate to provide sufficient fixing force. After the signal wire 10 is prepared, the pressing member 20 is sleeved on the wire skin 11 along the axial direction F1 to ensure that the pressing member 20 is located at one end of the wire skin 11 away from the wire core 12. Press the wire skin 11 and the wire core 12 along the longitudinal direction F2 by mechanical or manual means to ensure that the pressing member 20 can effectively fix the wire skin 11 and the wire core 12 to prevent sliding.

[0047] The crimping part 20 is sleeved on the wire sheath 11 of the signal wire 10 along the axial direction F1, and the wire sheath 11 and the wire core 12 are fixed together by longitudinal crimping F2. This connection structure provides additional mechanical fixing force to prevent the wire sheath 11 from sliding due to liquid pressure or the wire core 12 from falling off during the injection molding process, ensuring the stability of the signal wire 10.

[0048] Before injection molding, the signal wire 10 with the crimping part 20 installed is placed in the cooling cavity of the injection mold. The function of the cooling cavity is to solidify the shaping material through cooling after the injection molding liquid is injected into the mold, forming a connector assembly with the required shape.

[0049] Select and prepare a suitable signal wire 10, cut it into the required length according to the design requirements. Check the wire sheath 11 and the wire core 12 of the signal wire 10 to ensure there is no damage or defect. Prepare an appropriate crimping part 20 to ensure its size matches the wire sheath 11. After the signal wire 10 is prepared, sleeve the crimping part 20 on the wire sheath 11 along the axial direction F1, and the position should be at one end of the wire sheath 11 away from the wire core 12. By mechanical means or manual operation, crimp the wire sheath 11 and the wire core 12 along the longitudinal direction F2 to ensure that the two are in close contact and firmly fixed.

[0050] Place the signal wire 10 with the crimping part 20 in the cooling cavity of the injection mold, ensuring the correct position. Inject the injection molding liquid into the mold, and inject the liquid shaping material into the cooling cavity through the mold design.

[0051] After the injection molding liquid is injected, through the cooling effect of the cooling cavity, the shaping material is solidified to form an integrally molded injection molding part 220.

[0052] After cooling is completed, demold the injection molding part 220 from the mold. Check the injection molded signal connector 200 to ensure that the wire sheath 11 and the wire core 12 do not slide or fall off, the crimping part 20 is fixed well, and the overall quality of the connector is qualified.

[0053] It should be noted that: before injection molding, the wire sheath 11 and the wire core 12 have been crimped using the crimping part 20.

[0054] Before injection molding, the signal wire 10 and the connector have been fixedly connected to complete the electrical connection and are waiting for injection molding. During injection molding, the connected signal wire 10 and the connector are always placed in the cooling cavity of the injection mold.

[0055] Before injection molding, the first locking part 230 and the second locking part 240 have also been sleeved on the connector. When it is necessary to connect to an external port (not shown in the figure), the first locking part 230 and the second locking part 240 are removed in sequence. After the external port is connected to the connector, first sleeve the first locking part 230, and then sleeve the second locking part 240 and thread it with the connector.

[0056] In a specific embodiment, before injection molding, the pressing member 20 presses the wire sheath 11 and the wire core 12 along the longitudinal direction F2, increasing the friction between the wire sheath 11 and the wire core 12 in the longitudinal direction F2. During injection molding, the injection liquid flows in the cooling cavity. After injection molding, the signal wire 10 and the injection molded part 220 formed by cooling are integrally formed.

[0057] Specifically, the pressing along the longitudinal direction F2 increases the friction between the wire sheath 11 and the wire core 12, thereby preventing the wire sheath 11 from sliding due to liquid pressure during injection molding or the wire core 12 from falling off. By enhancing the friction, the stability and fixing effect of the wire sheath 11 and the wire core 12 can be ensured.

[0058] The injection liquid flows in the cooling cavity, and the desired shape of the signal connector 200 is formed through the design of the mold. During the flow, the injection liquid coats the signal wire 10 and is evenly distributed in the cooling cavity, ensuring the quality of injection molding.

[0059] Through the injection molding process, the signal wire 10 and the injection molded part 220 after cooling and solidification are tightly combined to form an integrally formed signal connector 200. This design ensures the stability and reliability of the signal wire 10 in the connector and improves the overall quality of the connector.

[0060] After the injection liquid flows in the mold, it is cooled through the cooling cavity, causing the injection liquid to quickly solidify and form a fixed shape. After the cooling and solidification are completed, the integrally formed signal connector 200 is demolded from the mold and subjected to quality inspection to ensure that the signal wire 10 and the injection molded part 220 are tightly combined without sliding or falling off.

[0061] The pressing member 20 presses the wire sheath 11 and the wire core 12 of the signal wire 10 along the longitudinal direction F2, preventing the wire sheath 11 from sliding by increasing the friction. This feature ensures the stability of the signal wire 10 during injection molding.

[0062] Through the cooling and solidification process, the signal wire 10 and the injection molded part 220 are integrally formed to form a complete signal connector 200. This structure improves the overall quality and reliability of the connector.

[0063] In a specific embodiment, the signal wire 10 includes a connection port 13. The connection port 13 is sleeved and connected to the wire core 12, and the connection port 13 is electrically connected to the wire core 12.

[0064] Specifically, the connection port 13 is used to achieve the electrical connection between the signal wire 10 and an external circuit or device. In this application, the connection port 13 is fixedly connected to the connector and is electrically connected to the external circuit through the connector and the connection port 13. Through sleeving and electrical connection, it is ensured that the signal can be stably transmitted while ensuring electrical performance and mechanical strength.

[0065] The connection port 13 is electrically connected to the wire core 12 by welding, crimping or other appropriate methods to ensure firm contact and reliable electrical connection.

[0066] The connection port 13 is fixed on the wire core 12 by means of socketting and realizes signal transmission through electrical connection. This connection structure ensures that the signal wire 10 can be stably connected to an external device or circuit, guaranteeing the stability and reliability of signal transmission.

[0067] Before injection molding, the connection port 13 and the pressing part 20 are assembled together onto the signal wire 10 to ensure the stability of the wire sheath 11 and the wire core 12 and the correct position of the connection port 13 during the injection molding process.

[0068] In a signal connector 200, it includes: a signal wire 10, a connecting part 210 and an injection molded part 220. Before injection molding, one end inside the connecting part 210 is connected to the signal wire 10. The connecting part 210 is placed in the cooling cavity of the injection mold, and the other end inside the connecting part 210 is connected to an external port for signal connection. The injection molded part 220 is formed by cooling and demolding the injection liquid, and the injection molded part 220 is integrally formed with the connecting part 210 and the signal wire 10.

[0069] It should be noted that: the external port is the connection port 13 of the device that generates signal transmission with the signal connector 200.

[0070] Specifically, the signal wire 10 is used to transmit electrical signals and is one of the core components of the signal connector 200. The signal wire 10 usually includes a wire core 12 and a wire sheath 11. The wire core 12 is responsible for conducting electrical signals, and the wire sheath 11 provides insulation protection.

[0071] Select a suitable signal wire 10 according to the electrical performance requirements of the connector, such as conductivity, insulation performance, wire diameter, etc. Cut the length of the signal wire 10 as needed and strip off an appropriate length of the wire sheath 11 to expose the wire core 12.

[0072] The connecting part 210 is used to electrically connect the signal wire 10 to an external device. One end of the connecting part 210 is connected to the signal wire 10, and the other end conducts signal transmission through an external port. The connecting part 210 fixes the position of the signal wire 10 during the injection molding process to ensure an integrated structure is formed after injection molding, increasing the overall strength and stability.

[0073] Select a suitable connecting part 210 according to the types of the signal wire 10 and the external port to ensure that their sizes and shapes match. Insert one end of the signal wire 10 into the inside of the connecting part 210 to ensure a firm connection and good contact. Place the connected signal wire 10 and the connecting part 210 together in the cooling cavity of the injection mold to ensure accurate positioning.

[0074] The injection molding part 220 forms the connector housing and support structure by the injection molding liquid flowing in the mold cooling cavity and cooling and solidifying. The injection molding part 220 integrates the connector 210 and the signal line 10 into one piece, ensuring the integrity and stability of the structure and improving the mechanical performance and durability of the connector.

[0075] One end of the signal line 10 is connected to the inside of the connector 210 to ensure reliable electrical connection. The connector 210 fixes the signal line 10 in the correct position to prevent it from sliding or falling off during the injection molding process.

[0076] The other end of the connector 210 is connected to an external port for signal transmission, which ensures a stable electrical connection between the external device and the signal line 10 .

[0077] The injection molded part 220 is solidified by cooling the injection liquid, and the connector 210 and the signal line 10 are integrally formed to form a structurally complete signal connector 200. This structure increases the mechanical strength and durability of the connector, and prevents the signal line 10 from loosening or falling off during use.

[0078] In a specific implementation example, the signal connector 200 includes a first locking member 230. The first locking member 230 is sleeved on the connector 210. The first locking member 230 is located at an end of the connector 210 away from the signal line 10. The first locking member 230 is sleeved at the connection between the external port and the connector 210.

[0079] Specifically, the first locking member 230 is used to fix the connection between the connector 210 and the external port to ensure the stability and reliability of the connection during use. It plays a role of mechanical fixing and protection to prevent the external port and the connector 210 from loosening or falling off when subjected to external force. According to the size and shape of the connector 210 and the external port, a suitable locking member is selected to ensure that they can be tightly sleeved.

[0080] In a specific implementation example, the signal connector 200 further includes a second locking member 240. The first locking member 230 is sleeved on the second locking member 240. The second locking member 240 is located between the first locking member 230 and the connecting member 210.

[0081] Specifically, the second locking member 240 provides additional fixation and protection, further enhancing the connection stability between the first locking member 230 and the connector 210. By adding the second locking member 240, the direct impact of external forces on the connector 210 and the signal line 10 can be reduced, and the mechanical strength and anti-vibration performance of the entire connector can be improved.

[0082] An appropriate second locking member 240 is selected according to the size and shape of the first locking member 230 and the connecting member 210 to ensure that it can be tightly sleeved between the first locking member 230 and the connecting member 210 .

[0083] Move the second locking member 240 axially along the connecting member 210 in the direction of F1 and slip it onto the connecting member 210. Ensure that the second locking member 240 is located between the first locking member 230 and the connecting member 210 and that it is tightly connected without looseness.

[0084] The second locking member 240 is slipped onto the connecting member 210 to provide additional fixation and protection against loosening of the connecting member 210 under external forces.

[0085] The first locking member 230 is slipped onto the second locking member 240 to ensure the connection stability between the first locking member 230 and the connecting member 210 and further enhance the overall mechanical strength.

[0086] In a specific embodiment, the connecting member 210 includes a locking portion 211 and a plastic portion 212. The first locking member 230 and the second locking member 240 are respectively slipped onto the locking portion 211. The plastic portion 212 is integrally formed with the locking portion 211. After injection molding, the plastic portion 212, the signal line 10 and the injection molded part 220 are integrally formed.

[0087] Specifically, the locking portion 211, as a part of the connecting member 210, provides the functions of fixation and positioning. It is used to accommodate and fix the first locking member 230 and the second locking member 240, ensuring that they are in the proper positions and preventing loosening and displacement.

[0088] Design the locking portion 211 according to the sizes and shapes of the first locking member 230 and the second locking member 240 to ensure that it can be tightly slipped onto them. Manufacture the locking portion 211 through precision machining to ensure its precise dimensions and tight fit with the locking members.

[0089] The plastic portion 212, as a part of the connecting member 210, is integrally formed with the locking portion 211 to provide additional mechanical strength and stability. After injection molding, the plastic portion 212, the signal line 10 and the injection molded part 220 are integrally formed to ensure the structural integrity and reliability of the entire connector.

[0090] Determine the shape and size of the plastic portion 212 according to the overall design of the connecting member 210 to ensure its integral formation with the locking portion 211.

[0091] Manufacture the plastic portion 212 through an injection molding process to ensure its integral formation with the locking portion 211, precise dimensions and reliable quality.

[0092] The locking portion 211 provides a fixed position for accommodating the first locking member 230 and the second locking member 240. Through the locking portion 211, the locking members are accurately positioned and fixed, preventing loosening and displacement.

[0093] The plastic part 212 and the locking part 211 are integrally formed, providing additional mechanical strength and stability. After injection molding, the plastic part 212, the signal line 10, and the injection molded part 220 are integrally formed, ensuring the structural integrity and reliability of the entire connector.

[0094] In a specific embodiment, the connector 210 further includes: a connection hole 213. The connection hole 213 penetrates through the inside of the locking part 211 and the plastic part 212 respectively. A connection port 13 is placed at one end of the connection hole 213, and the external port is placed at the other end of the connection hole 213. The external port and the connection port 13 are electrically connected through the connection hole 213.

[0095] Specifically, the connection hole 213 provides a channel through which the signal line 10 inside the connector 210 can be electrically connected to the external port and the connection port 13. In this way, signals can be smoothly transmitted from the signal line 10 through the connection hole 213 to the external device, realizing signal transmission and connection.

[0096] The connection hole 213 is designed according to the dimensions and positions of the signal line 10, the connection port 13, and the external port to ensure that it can penetrate through the locking part 211 and the plastic part 212 and provide sufficient space for electrical connection.

[0097] Holes are drilled in the locking part 211 and the plastic part 212 to ensure accurate hole diameters and positions so that the connection port 13 and the external port can be correctly installed and connected.

[0098] Place the connection port 13 at one end of the connection hole 213 and ensure its electrical connection to the signal line 10. Place the external port at the other end of the connection hole 213 and ensure its electrical connection to the connection port 13.

[0099] The connection hole 213 penetrates through the locking part 211 and the plastic part 212, providing a channel for the electrical connection of the signal line 10. This design ensures a stable and reliable electrical connection between the signal line 10 and the external device.

[0100] One end of the connection hole 213 is connected to the connection port 13, and the other end is connected to the external port. Through the connection hole 213, the electrical signal of the signal line 10 can be transmitted from the connection port 13 to the external port, realizing signal transmission and connection.

[0101] In a specific embodiment, the injection molded part 220 includes an inner injection molded part 221. The plastic part and the signal line 10 are located inside the inner injection molded part 221. And the plastic part 212, the signal line 10, and the inner injection molded part 221 are integrally formed.

[0102] Specifically, the inner injection part 221 provides an additional protective layer that wraps the signal line 10 and the plastic part, enhancing the mechanical strength and environmental protection performance of the signal connector 200. Through integral molding, the position of the signal line 10 within the connector is ensured to be stable, preventing movement or loosening and improving the overall reliability of the connector.

[0103] The inner injection part 221 wraps the signal line 10, providing additional mechanical protection against damage to the signal line 10 from the external environment.

[0104] The inner injection part 221 is integrally molded with the plastic part 212, increasing the overall mechanical strength and stability of the connector and ensuring the stable position of the signal line 10 within the connector.

[0105] Through the integral molding process, it is ensured that the inner injection part 221, the signal line 10, and the plastic part 212 are tightly combined, improving the reliability and durability of the connector.

[0106] In a specific embodiment, the injection molded part 220 further includes an outer injection part 222. The outer injection part 222 is integrally molded with the inner injection part 221. The inner injection part 221 is located inside the outer injection part 222.

[0107] Specifically, the inner injection part 221 is located inside the injection molded part 220 of the signal connector 200 and is integrally molded with the signal line 10. It wraps the signal line 10, protecting and fixing the position of the signal line 10 and forming a tight bond with the signal line 10.

[0108] The main function of the inner injection part 221 is to provide mechanical support and fix the position of the signal line 10, preventing the signal line 10 from moving or being damaged during use. In addition, it can also enhance the structural strength and stability of the connector, ensuring the reliability of the connection signal.

[0109] The outer injection part 222 is the part formed by injection molding outside the inner injection part 221, making the surface of the entire connector smooth and having a certain aesthetic appearance.

[0110] The outer injection part 222 not only provides external appearance protection and decorative effects for the connector but also can further enhance the durability and protection performance of the overall structure. It ensures that the inner injection part 221 and the signal line 10 are protected from external environmental factors such as moisture, chemical substances, or mechanical shocks.

[0111] The above are only the implementation manners of the present application. It should be noted here that for those of ordinary skill in the art, improvements can be made without departing from the creative concept of the present application, but these all fall within the protection scope of the present application.
