Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cable connectors, more specifically, relates to an improved cable connector convenient to maintain. BACKGROUND

[0002] In the field of cable connection, traditional connectors have a series of problems, which seriously affect the reliability, durability and convenience of maintenance of the connection.

[0003] Cable plugging problem: During the plugging process of traditional cable connectors, due to the lack of effective air exhaust structure, resistance is easily generated due to the accumulation of internal air when the cable is inserted, which leads to unsmooth insertion. This not only increases the operation difficulty, but also may cause damage to the main needle and the front needle, affecting the service life of the connector. Moreover, when pulling out the cable, air pressure difference is easily formed, which also increases the difficulty of pulling out and reduces the work efficiency.

[0004] Needle damage and maintenance problem: The needle of the traditional connector is usually designed in one piece. When the needle is damaged, especially when the lower needle is damaged or needs to be cut short due to installation, the entire connector body often needs to be replaced. This not only has high cost, but also causes unnecessary waste, especially in some scenarios where connectors are used on a large scale. Frequent replacement of connectors will greatly increase the maintenance cost.

[0005] Inconvenience of needle replacement: Even if some connectors allow needle replacement, the replacement process is relatively complex. The traditional needle connection method makes it difficult for heating tools to effectively conduct heat to the connection, increasing the difficulty of disassembling and damaging the needle. Moreover, in the installation of new needles, there is a lack of precise positioning structure, which easily leads to the inclination of the needle position, affecting the welding quality and further affecting the electrical performance of the connector.

[0006] Welding quality and stability: In terms of needle welding, the fixing method of soldering tin in traditional connectors is not stable enough. The soldering tin often cannot uniformly surround the connection between the main needle and the lower needle. When subjected to external forces, the connection is easily broken, reducing the reliability of the connector and failing to meet the requirements of some high-stability application scenarios.

[0007] Air circulation and quick plugging: In the process of quick plugging of the cable, the air circulation design of the traditional connector is unreasonable, which cannot quickly and effectively exhaust or supplement air. This may cause air to accumulate in a local area, affecting the smoothness of plugging, and in the process of quick plugging, excessive resistance may also damage the gold plating layer and oxidation film on the surface of the main needle and the front needle, reducing the electrical performance and corrosion resistance of the connector.

[0008] In summary, the existing cable connector has obvious deficiencies in cable plugging, pin damage repair, welding quality and air flow, and cannot meet the needs of modern electronic equipment for efficient, reliable, durable and easy-to-repair connectors. SUMMARY

[0009] In order to solve the above technical problems, the present application provides an improved cable connector for easy maintenance to solve the above problems.

[0013] Preferably, the air flow channels are distributed around the main needle and the front needle, and each air flow channel is independently distributed, each air flow channel extends from the front needle to the end of the main needle cross section, the surface of the main needle and the front needle is provided with a side flow channel, the side wall of the main needle and the front needle is provided with a tail flow channel, and the side flow channel and the tail flow channel are interconnected, the two air flow channels on the upper surface and the side edge of the main needle and the front needle are interconnected by the side flow channel and the tail flow channel, the cross section of each air flow channel is trapezoidal, and the size of the air flow channel flow channel gradually increases from the initial end of the front needle to the end of the main needle, the front side of the connector body is provided with a front slot, the inner wall of the front slot is also provided with an air inlet groove, the cable is installed in the front slot, the front slot is provided with an air inlet groove which is the same as the needle fixing frame, and the air inlet groove faces one side of the connector body.

[0014] Compared with the prior art, the present application has the following advantages: In the present application, when the cable plug-in connector body is inserted into the front slot of the connector body, the needle hole in the inner wall of the cable will be fitted around the front needle at the front end of the main needle, at this time, the air flow channel on the surface of the front needle can play an air exhaust effect, effectively improving the smoothness of the cable insertion, reducing the damage probability of the main needle and the front needle, and the front needle at the front end of the main needle can be detached, the lower needle at the lower end of the main needle can also be detached, and after subsequent damage, it can also be quickly repaired, effectively improving the durability of the connector body.

[0015] In the present application, when the connector body is installed, the plurality of lower needles below the needle fixing frame need to be welded with components such as circuit boards, and the lower needles often need to be cut according to the situation, when the lower needle is damaged or too short, the whole connector body needs to be replaced, the present device can replace the lower needle independently, and a brand new lower needle is inserted into the needle slot from the bottom of the needle fixing frame, and the top of the lower needle is connected with the main needle, so that the whole connector body does not need to be replaced, and the durability of the connector body is effectively improved.

[0016] In the present application, when the lower needle needs to be replaced, a heating tool such as an air gun is used to heat the connection between the lower needle and the main needle, since the needle slot is provided with air inlet grooves upward and downward, and the air inlet grooves are provided with inclined grooves, the heating assembly such as the air gun can effectively conduct heat to the connection between the main needle and the lower needle, then the damaged lower needle is removed, and a brand new lower needle is inserted into the needle slot, the conical mounting groove at the top of the lower needle is fitted around the conical connecting end, the conical connecting end and the conical mounting groove can play a positioning role, speed up the installation speed, and the conical connecting end and the conical mounting groove cooperate to effectively prevent the lower needle from being positionally deviated, and ensure the welding quality.

[0017] In the present invention, the solder is melted into the buffer groove at the bottom of the bevel groove, and the solder will flow into the tin inlet groove along the buffer groove. Since the tin inlet groove forms a ring at the connection between the main pin and the lower pin, the solder will be fixed in a ring shape around the main pin and the lower pin for four circles, so that the two can be connected more stably. After the connection, the main pin and the lower pin are protected in the pin slot, and the connection will not be broken due to external force, which greatly improves the convenience of maintenance.

[0018] In the present invention, the cross-section of each air circulation groove is trapezoidal, and the size of the air circulation groove flow channel gradually increases from the initial end of the front pin to the end of the main pin. When the cable is inserted into the outside of the main pin and the front pin, the air circulation groove outside the main pin and the front pin can effectively discharge the air in the cable. When the cable is pulled out, the external air quickly enters the cable through the air circulation groove, effectively avoiding the formation of air pressure difference and speeding up the smoothness of plugging and unplugging. At the same time, the volume of the air circulation groove of this device becomes larger and larger from front to back, which is more adapted to actual usage. As the insertion becomes deeper, the exhaust volume increases, further improving the smoothness of insertion.

[0019] In the present invention, the two air circulation grooves are connected by side flow grooves and tail flow grooves, so as to adapt to the rapid plugging and unplugging of cables. The side flow grooves and tail flow grooves can quickly connect the exhaust, which can prevent the phenomenon of excessive air on one side, further improve the overall exhaust smoothness, effectively reduce the stability of cables and main pins and front pins during rapid plugging and unplugging, and effectively reduce the probability of damage to the gold plating layer on the surface of the main pins and the front pins and rupture of the oxide film.

[0024] The side wall of each air inlet slot 15 is provided with a bevel slot 16, and the bevel slot 16 faces the back of the pin fixed frame 14. The pin fixed frame 14 is provided with a tin inlet slot 18 at the connection between the pin slot 19 and the air inlet slot 15. The connection between the bevel slot 16 and the pin slot 19 is provided with a buffer slot 17. The cross section of the tin inlet slot 18 is U-shaped, and the three sides of the tin inlet slot 18 are equidistant. The opening faces the bevel slot 16. The buffer slot 17 is in communication with the two side openings of the tin inlet slot 18. When the connector body 1 is installed, the plurality of lower pins 23 below the pin fixed frame 14 need to be welded with the circuit board and other components. The lower pins 23 often need to be cut according to the situation. When the lower pins 23 are damaged or too short, the connector body 1 needs to be replaced as a whole. The device can replace the lower pins 23 independently. The new lower pins 23 are inserted into the pin slot 19 from the bottom of the pin fixed frame 14.

The solder flows into the tin inlet slot 18 along the buffer slot 17. Since the tin inlet slot 18 forms a ring at the connection between the main pin 2 and the lower pin 23, the solder is fixed in a ring shape around the main pin 2 and the lower pin 23. Thus, the two can be more stably connected. The connected main pin 2 and lower pin 23 are protected in the pin slot 19 and will not be broken due to external force. The convenience of maintenance is greatly improved.
