Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically to a communication connector. Background Technology

[0002] In modern communication technology, communication connectors are key components for signal transmission in electronic devices. They typically use two pins as the core conductive components, with a communication resistor placed between the pins to achieve impedance matching and stable signal transmission. To ensure the normal operation of communication connectors in different environments, existing connector structures generally employ simple sealing measures, often using O-rings or local potting for basic protection, thus blocking the influence of external dust, moisture, etc., on the internal circuitry. However, these traditional sealing methods have the following shortcomings in practical applications: While potting structures can cover local areas, the adhesive layer is prone to problems such as bubbles, cracks, or weak adhesion to the shell, resulting in poor sealing consistency; O-rings only provide line contact sealing to the mating surfaces of the connector shell, failing to create a comprehensive and continuous sealing path around the pins and resistor. Leakage channels still exist in the gaps, allowing vapors and oils to easily penetrate the interior, leading to resistor oxidation, resistance drift, and faults such as signal attenuation and unstable transmission. With the rapid development of communication technology, the performance requirements for communication connectors are also increasing. Traditional sealing structures have low reliability and cannot meet the requirements for long-term stable use of high-reliability communication connectors. Therefore, it is urgent to optimize the design of existing sealing structures to improve the sealing performance of products. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the low reliability of traditional simple sealing measures in existing communication connectors, which cannot form a safe sealing protection for the pins and resistors, and are difficult to meet the requirements of long-term stable use of products; thereby providing a communication connector that can achieve sealed protection for core components such as communication resistors, ensure signal transmission stability, and improve the long-term stability and reliability of products.

[0004] To solve the above-mentioned technical problems, this utility model provides a communication connector, including a connector socket and a connector female base. The connector female base includes a female base housing, conductive terminals, and a communication resistor. One end of the female base housing is provided with a plug interface, and the other end is provided with a sealing component to seal its port. At least two conductive terminals are spaced apart inside the female base housing, one end of each conductive terminal extending to the plug interface of the female base housing. The communication resistor is connected in series between the two conductive terminals and is housed in the other end of the female base housing. The sealing component includes:

[0005] A sealing sleeve is installed inside the other end of the female housing, and the sealing sleeve has a groove cavity to accommodate the communication resistor;

[0006] A sealing cap is fitted over the other end of the female housing and covers the sealing sleeve.

[0007] In the aforementioned communication connector, the outer peripheral wall of the sealing sleeve is provided with multiple annular first sealing ribs, which are distributed at intervals along the axial direction of the sealing sleeve. The first sealing ribs are interference-fitted with the inner wall of the female housing to form a multi-stage circumferential seal.

[0008] In the aforementioned communication connector, the sealing cover is a plastic cover and is ultrasonically welded to the other end of the female housing, so that the inner peripheral wall of the sealing cover is sealed and fitted to the outer peripheral wall of the female housing.

[0009] In the aforementioned communication connector, one end of the conductive terminal is a pin structure that passes through the connector, and the other end is provided with a crimping structure for connecting the communication resistor. The two leads of the communication resistor are respectively connected to the other ends of the two conductive terminals.

[0010] In the aforementioned communication connector, the crimping structure includes a connecting groove disposed at the other end of the conductive terminal, and a plurality of crimping blocks formed on both sides of the connecting groove. The leads of the communication resistor extend into the corresponding connecting grooves and are crimped and fixed onto the leads of the communication resistor by the crimping blocks to achieve an electrical connection between the conductive terminal and the communication resistor.

[0011] In the aforementioned communication connector, the female socket housing has a sealing inner sleeve inside the insertion interface. The sealing inner sleeve fits against the inner wall of the insertion interface and is used to form a sealing fit with the outer wall of the connector socket when the connector socket and the connector female socket are inserted.

[0012] In the aforementioned communication connector, the connector socket includes a socket housing, two socket terminals, a sealing plug, and wires; one end of the socket housing is adapted to connect with the insertion interface of the female housing, the two socket terminals are disposed in the insertion holes of the socket housing for insertion and mating with the conductive terminals, the sealing plug is installed in the other port of the socket housing and has a through hole matching the number of wires, and the wires pass through the through holes and are electrically connected to the corresponding socket terminals.

[0013] In the aforementioned communication connector, the outer wall of the sealing plug is provided with multiple annular second sealing ribs, which are spaced apart along the axial direction of the sealing plug, and the second sealing ribs are sealed to the inner wall of the socket housing.

[0014] In the aforementioned communication connector, the inner wall of the wire hole is provided with at least one annular sealing rib, and the annular sealing rib is interference-fitted with the outer wall of the wire.

[0015] The technical solution of this utility model has the following advantages compared with the prior art:

[0016] 1. In the communication connector provided by this utility model, the end of the female connector shell away from the insertion interface adopts a double-layer sealing component design with an internal sealing sleeve and an external sealing cover. First, the sealing sleeve forms a first sealing barrier inside the female connector, and then the sealing cover externally covers and seals the end of the female connector. The sealing sleeve has a specially designed groove cavity to accommodate the communication resistor, physically isolating and encasing the resistor. This comprehensively seals off the intrusion gaps of dust, moisture, and oil, effectively preventing resistor oxidation and resistance drift. It achieves comprehensive sealing protection for core components such as communication resistors and conductive terminals, ensuring signal transmission stability. Structurally, it solves the problem of leakage channels in traditional sealing methods, significantly improving overall sealing reliability. The connector female connector using this technical solution achieves a sealed insertion with the connector socket through the insertion interface. The sealing component completely seals the other end of the female connector shell, blocking the intrusion of external environmental factors. This allows the communication connector to work stably for a long time in harsh environments such as high humidity, high dust, and oil contamination. This structural design improves the product's sealing performance and environmental adaptability, significantly enhancing the long-term stability and reliability of the communication connector.

[0017] 2. In the communication connector provided by this utility model, the outer peripheral wall of the sealing sleeve is provided with multiple annular first sealing ribs, which are distributed at intervals along the axial direction. Through interference fit with the inner wall of the female socket, a multi-level independent circumferential sealing barrier is formed, which avoids the overall sealing failure caused by single-point failure and improves the sealing redundancy. When the first sealing ribs are interference fitted with the inner wall of the female socket, they will generate elastic deformation, which accurately fills the tiny gap between the sealing sleeve and the inner wall of the shell, forming a physical barrier in both the axial and circumferential directions, blocking the environmental intrusion path in all directions, and realizing the sealing protection of the end of the connector female socket with communication resistor.

[0018] 3. In the communication connector provided by this utility model, the plastic sealing cover and the female housing are fused together at the molecular level by ultrasonic welding to form a non-removable permanent sealed connection. This makes the inner peripheral wall of the sealing cover fit tightly with the outer peripheral wall of the female housing. Based on the multi-level sealing inside the sealing sleeve, an external second sealing barrier is formed. Together with the internal sealing structure, a double-layer protection system is constructed. At the other end of the connector female housing, multiple sealing barriers are formed from the inside to the outside, completely isolating environmental factors such as moisture, dust, and oil, ensuring stable electrical performance and extending the service life of the connector.

[0028] Example

[0029] The following is a detailed description of this embodiment with reference to the accompanying drawings:

[0030] This implementation provides, for example Figures 1-4 The communication connector shown includes a connector socket 200 and a connector female socket 100. The connector female socket 100 includes a female socket housing 1, conductive terminals 2, and a communication resistor 3. One end of the female socket housing 1 is provided with a plug interface 11, and the other end is provided with a sealing assembly to seal its port. At least two conductive terminals 2 are spaced apart inside the female socket housing 1, and one end of each conductive terminal 2 extends to the plug interface 11 of the female socket housing 1. The communication resistor 3 is connected in series between the two conductive terminals 2 and is housed in the other end of the female socket housing 1. The sealing assembly includes a sealing sleeve 4 and a sealing cover 5. The sealing sleeve 4 is installed inside the other end of the female socket housing 1 and has a groove cavity 41 for accommodating the communication resistor 3. The sealing cover 5 is sleeved outside the other end of the female socket housing 1 and covers the sealing sleeve 4.

[0031] In the above embodiment, the other end of the female socket housing 1 away from the plug interface 11 adopts a double-layer sealing component design of an inner sealing sleeve 4 and an outer sealing cover 5. First, the sealing sleeve 4 forms a first sealing barrier inside the female socket, and then the sealing cover 5 externally covers and seals the end of the female socket. The sealing sleeve 4 has a groove cavity 41 specifically for accommodating the communication resistor 3, which physically isolates and wraps the resistor. This completely seals the gaps for the intrusion of dust, water vapor, and oil, effectively preventing the resistor from oxidizing and the resistance value from drifting. It achieves all-round sealing protection for core components such as the communication resistor 3 and the conductive terminal 2, ensuring the stability of signal transmission. Structurally, it solves the problem of leakage channels in traditional sealing methods and greatly improves the overall sealing reliability. The connector female socket 100 using this technical solution achieves a sealed mating with the connector receptacle 200 through the insertion interface. The other end of the female socket housing is completely sealed by the sealing component, preventing the intrusion of external environmental factors. This allows the communication connector to work stably for a long time in harsh environments such as high humidity, high dust, and oil. This structural design improves the sealing performance and environmental adaptability of the product, meets the stringent requirements of high-reliability communication equipment for connector life and environmental adaptability, and significantly improves the long-term stability and reliability of the communication connector.

[0032] The following is combined Figures 2-4 The specific installation methods for the sealing sleeve and sealing cap are explained in detail:

[0033] The outer peripheral wall of the sealing sleeve 4 is provided with multiple annular first sealing ribs 42. The multiple first sealing ribs 42 are distributed at intervals along the axial direction of the sealing sleeve 4. The first sealing ribs 42 are interference-fitted with the inner wall of the female socket 1 to form a multi-level circumferential seal. This structural design, through the interference fit between the multiple first sealing ribs 42 and the inner wall of the female socket 1, forms a multi-level independent circumferential sealing barrier, avoiding overall seal failure caused by single-point failure, and improving seal redundancy. When the first sealing ribs 42 are interference-fitted with the inner wall of the female socket, they will generate elastic deformation, which can fill the tiny gap between the sealing sleeve and the inner wall of the female socket to form a physical barrier, blocking the environmental intrusion path in all directions, and achieving sealing protection for the end of the connector female socket 100 with the communication resistor.

[0034] In a further preferred configuration, the sealing cover 5 is a plastic cover and is ultrasonically welded to the other end of the female connector shell 1. The ultrasonic welding of the plastic sealing cover and the female connector shell achieves molecular-level fusion, forming a permanent, non-removable seal. This ensures that the inner circumferential wall of the sealing cover 5 is tightly fitted to the outer circumferential wall of the female connector shell 1. Based on the multi-level sealing of the sealing sleeve, a second external sealing barrier is formed. Through the synergistic sealing effect of the inner and outer surfaces of the sealing sleeve 4 and the sealing cover 5, a double-layer protection system is constructed, thereby forming multiple sealing barriers from the inside out at the other end of the connector female connector 100. This completely isolates environmental factors such as moisture, dust, and oil, ensuring stable electrical performance and extending the connector's service life.

[0035] In this embodiment, one end of the conductive terminal 2 is a pin structure 22 that passes through the insertion interface 11. The pin structure 22 can be stably inserted into the corresponding socket of the connector socket 200 to achieve mechanical locking and electrical conduction, ensuring the reliability of the connector front-end insertion and removal function. The insertion interface 11 of the female socket housing 1 is provided with a sealing inner sleeve 12. The sealing inner sleeve 12 fits against the inner wall of the insertion interface 11 and is used to form a sealing fit with the outer wall of the connector socket 200 when the connector socket 200 and the connector female socket 100 are inserted. A locking structure is also provided between the connector socket 200 and the connector female socket 100 to keep their relative positions fixed.

[0036] like Figure 4As shown, the other end of the conductive terminal 2 is provided with a crimping structure for connecting the communication resistor 3. The two leads of the communication resistor 3 are respectively connected to the other ends of the two conductive terminals 2. Specifically, the crimping structure includes a connecting groove provided at the other end of the conductive terminal 2, and a plurality of crimping blocks 21 formed on both sides of the connecting groove. The leads of the communication resistor 3 extend into the corresponding connecting grooves and are crimped and fixed on the leads of the communication resistor by the crimping blocks 21 to realize the electrical connection between the conductive terminal 2 and the communication resistor 3. This structural design provides physical limits and positioning references for the leads of the communication resistor 3 through the connecting groove. During assembly, the resistor leads can be quickly and accurately placed into the corresponding positions. Then, multiple pressing blocks 21 are simultaneously pressed onto the resistor leads from both sides through a pressing process, forming multi-point clamping force, which greatly improves the mechanical fixing strength of the resistor leads and can effectively resist external forces such as vibration, pulling, and impact. The pressing causes the metal conductive terminals and resistor leads to plastic deformation, forming a tight surface contact with lower and more stable contact resistance, ensuring stable transmission of communication signals. Using this structural design, the two conductive terminals 2 and the communication resistor 3 can be first assembled into an integral module by pressing, and then the whole module can be installed into the female housing 1, avoiding the alignment deviation when assembling the conductive terminals and the communication resistor separately, greatly improving assembly efficiency and positioning accuracy.

[0037] The following is combined Figures 2-4 The specific structure of the connector socket is described in detail below:

[0038] The connector socket 200 includes a socket housing 6, two socket terminals 7, a sealing plug 8, and wires 9. One end of the socket housing 6 is adapted to the insertion interface 11 of the female housing 1. The two socket terminals 7 are disposed in the insertion holes of the socket housing 6 for insertion and mating with the conductive terminals 2. The sealing plug 8 is installed in the other end of the socket housing 6 and has a threading hole matching the number of wires 9. After the wires 9 pass through the threading holes, they are electrically connected to the corresponding socket terminals 7. The sealing plug 8 is made of rubber. The inner wall of the threading hole has at least one annular sealing rib. The annular sealing rib is interference-fitted with the outer wall of the wire 9, and the annular rib generates a ring-shaped high-pressure seal on the surface of the wire 9, completely blocking the tiny gap between the wire and the threading hole, preventing moisture and dust from entering the socket interior along the surface of the wire. Further preferably, the sealing plug 8... The outer wall of the sealing head 8 is provided with multiple annular second sealing ribs 81. These multiple second sealing ribs 81 are distributed at intervals along the axial direction of the sealing head 8. The second sealing ribs 81 are in a sealing fit with the inner wall of the socket housing 6. During the process of pressing the sealing head 8 into the socket housing, the compression deformation of the second sealing ribs 81 can adaptively fill the gaps caused by manufacturing tolerances. The multiple second sealing ribs 81 form multiple circumferential sealing barriers between the sealing head and the inner wall of the socket housing, ensuring the sealing performance of the connection between the sealing head and the socket housing. This connector socket structural design, through the combination of the sealing head, multi-level sealing ribs, and annular sealing ribs of the wire hole, provides an efficient sealing effect on the tail port and wire insertion part of the connector socket. It not only ensures the basic plugging and electrical connection functions, but also achieves highly reliable sealing protection, significantly improving the reliability and service life of the product.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
