[0001] The invention relates to the technical field of connectors, in particular to a brush-shaped connector. Background Art

[0002] An electrical connector is an electronic engineering device used to connect two active devices to achieve the transmission of current or signals.

[0003] Electrical connectors play a vital role in electronic engineering. They not only need to meet general performance requirements, but also must meet the standards of good contact, reliable operation, and easy maintenance. Whether they work reliably directly affects the normal operation of the aircraft circuit and even the safety of the entire host system. Therefore, there are very strict requirements for the quality and reliability of electrical connectors. Electrical connectors are widely used, including but not limited to aviation, aerospace and other systems, as well as various electrical circuits, to connect or disconnect current or signals.

[0004] There are many ways to classify electrical connectors, which can be divided according to appearance, structure, purpose, etc. For example, cylindrical contacts, twisted wire spring-type insertion pin contacts, coil insertion contacts, crown spring-type contacts, and square contacts. Among these contacts, the advantage of coil insertion contacts is that the insertion force is small, but the wire may break, and because its size is restricted by its own structure and jacket, its volume is relatively large; twisted wire spring-type insertion pin contacts can achieve miniaturization, but its insertion force is large; crown spring-type contacts also show great deficiencies in insertion force. These contacts are not suitable for environments that require high density, multiple cores, low insertion force, and low-level signal transmission. At the same time, in some special environments, a connector with a more reliable connection and a shorter spacing between terminals is required. Summary of the invention

[0027] In a specific implementation, the ejector pin 3 is arranged at the center of the cathode connector 18 close to the end surface of the single needle 2, and the number of the single needles 2 is 6.

[0028] When this brush-shaped connector is used, the brush-shaped pin at the end of the anode terminal 1 is inserted into the sheath 4 of the cathode terminal 18. At this time, the inner walls of the multiple single pins 2 on the brush-shaped pin are connected to the outer wall of the ejector pin 3, and one end of the ejector pin 3 is connected to the inner wall of the anode terminal 1. At the same time, the outer wall of the single pin 2 of the brush-shaped pin of the anode terminal 1 is connected to the inner wall of the sheath 4. After this setting, when the pin contacts the ejector pin 3, it is separated from the point contact in the prior art and changed to surface contact. At the same time, the connection efficiency is not affected after application, the connection is more stable, and the service life is longer. After the connector is connected, the connector connection is more reliable, and the spacing between the connection terminals can be reduced to 1.27mm.

[0029] Embodiment 2 On the basis of Example 1, the applicant considers that the connection between the cathode and the anode joint 1 is more stable, and provides a gap of 0.05-0.1 mm between each of the single needles 2. One end of multiple single needles 2 is fixedly connected to the anode joint 1, and they are all arranged perpendicular to the outer wall of the anode joint 1 to form a circular tube.

[0030] The inner wall of the end of the single needle 2 away from the anode connector 1 is provided with an inwardly inclined arc bevel 7, the end of the single needle 2 away from the anode connector 1 is horizontally arranged, and the outer wall of the end of the single needle 2 away from the anode connector 1 is provided with an outwardly beveled arc slope 6. The inner diameter of the circular tube formed by the bevels 7 of the multiple single needles 2 and the inner wall of the anode connector 1 is 0.02-0.05mm smaller than the outer diameter of the ejector pin 3. The spacing between the outer wall of the ejector pin 3 and the inner wall of the sheath 4 is greater than the thickness of the single needle 2 0.01-0.03mm.

[0031] After the above application, when the brush-like plug composed of the single needles 2 is inserted into the ejector pin 3, the inner diameter of the circular tube formed by the multiple single needles 2 is smaller than the outer diameter of the ejector pin 3. Therefore, when the ejector pin 3 is inserted into the circular tube, the ejector pin 3 will expand a part of the circular tube. At this time, the bevel 7 of the inner wall of the single needle 2 will make it easier for the ejector pin 3 to be inserted, and the bevel 6 of the outer wall of the single needle 2 will make it easier to insert the expanded circular tube into the sheath 4. After insertion, the connector composed of the integral cathode connector 18 and the anode connector 1 is more stable on the basis of the first embodiment.

[0032] Embodiment 3 On the basis of the first and second embodiments, the applicant considers that if there is a certain gap between the sheath 4, the ejector pin 3 and the single needle 2 after the brush-like pin is inserted into the sheath 4, the connection stability will definitely be affected.

[0033] After considering the above issues, if Figure 6 , Figure 8-9 The cathode connector 18 comprises a base 5, wherein a sandwich is provided in the base 5, wherein a plurality of telescopic rods 9 are provided in the sandwich and penetrate the outer wall of the base 5 and are arranged perpendicularly to the ejector pin 3, wherein the inner wall of the sheath 4 is fixedly connected to one end of the plurality of telescopic rods 9 away from the ejector pin 3, and the surface of the base 5 provided with the ejector pin 3 is a plurality of telescopic disks 8 which are sleeved with each other, and the outer wall of the telescopic disk 8 is fixedly connected to the inner wall of the sheath 4; The sheath 4 is provided with two fixed blocks 12 and an insert block 13 that are movably connected to each other. The inner wall of the insert block 13 is provided with a plurality of first latch teeth 14 at equal intervals. The first latch teeth 14 are provided with an oblique groove on one side close to the fixed shell. The outer wall of the insert block 13 close to the first latch teeth 14 is provided with a plurality of second latch teeth 15 at equal intervals. The second latch teeth 15 and the first latch teeth 14 are mutually connected. A limiting groove 16 and a limiting block 17 are provided between the insert block 13 and the fixed block 12.

[0034] After the above application, after the brush-shaped pin is inserted into the sheath 4 in the cathode connector 18 according to the steps of the second embodiment, the sheath 4 can further insert the plug block 13 in the sheath 4 into the fixed block 12 at the other end of the sheath 4 by controlling the telescopic rod 9 and the telescopic disk 8 in the base 5. Through the connection between the first clamping tooth 14 and the second clamping tooth 15 between the plug block 13 and the fixed block 12, the plug block 13 is inserted into the fixed block 12 so that the sheath 4 is tightly in contact with the outer wall of the circular tube composed of multiple single pins 2. On the basis of the second embodiment, the stability of the contact is increased. At the same time, after the second application, the applicability is stronger. Even if the size of the single pin 2 changes, the sheath 4 can be adjusted in time to complete the connection, which is very suitable in the field of connectors. Moreover, after the first clamping tooth 14 and the second clamping tooth 15 of the sheath 4 are locked, the telescopic rod 9 and the telescopic disk 8 will not be adjusted, and the stability of the base 5 will not be affected. At the same time, after the overall application, the spacing between the connection terminals can be reduced to 1.03-1.10mm. .

A sleeve 10 threadedly connected to the outer wall of the connecting block 11 is provided on the outer wall of the anode connector 1 .

[0036] After the application, after the cathode terminal 18 and the anode terminal 1 are connected, the connection of the connecting block 11 and the sleeve 10 can make the entire connector more stable and have better sealing.
