Technical Field

[0002] Connectors, as a key component connecting two active devices, play a vital role in transmitting current or signals. In today's rapidly developing social economy, the demand for various types of connectors in many industries such as medical, mechanical electronics, and automotive electronics is showing a broad and huge trend. These connectors not only meet the needs of various industries for efficient and stable transmission, but also play an indispensable role in promoting scientific and technological progress and improving production efficiency.

The clip terminal and the pin have only two contact points, the upper and lower contact points, and the contact area is relatively small. The contact impedance between the clip terminal and the pin will be relatively large, resulting in poor electrical performance. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Combination Figures 1 to 4 A low-impedance connector socket shown in the figure comprises a socket housing 1, a plurality of pin terminals 2 are arranged on the inner side of the socket housing 1, a conductive rod 3 is fixedly arranged at one end of the pin terminal 2, the conductive rod 3 penetrates the socket housing 1 and is connected by a snap-fit, a spiral rod 4 is arranged on the outer side of the conductive rod 3, a fixing ring 5 is arranged at one end of the spiral rod 4, the fixing ring 5 is fixedly connected to the conductive rod 3, and the fixing ring 5 is connected to the socket housing 1 by a snap-fit.

[0021] Both ends of the socket housing 1 are fixed with connecting plates 11, the top of the socket housing 1 is provided with a docking groove 12, the inner sides of the top wall and the bottom wall of the socket housing 1 are provided with a card groove 13, and both sides of the socket housing 1 are provided with a U-shaped positioning groove 14. The connecting plate 11 connects and fixes the socket housing 1 to the circuit board, and the docking groove 12, the card groove 13, and the U-shaped positioning groove 14 facilitate the positioning and plugging of the connector plug and the socket housing 1.

[0022] Conductive sheets 21 are embedded on the top and bottom of the pin terminal 2, and semi-cylindrical conductive blocks 22 are embedded on both sides of the pin terminal 2. The conductive sheets 21 and the conductive blocks 22 are connected to the pin terminal 2 by welding. The conductive sheets 21 and the conductive blocks 22 are made of metal with high conductivity and are in contact with the clip terminals in the connector plug, which can minimize the resistance when the contact area is fixed.

[0023] A spiral groove 31 is provided on the conductive rod 3, and the spiral rod 4 is located in the spiral groove 31 and connected by welding. The wire is wound and fixed on the spiral rod 4, and the spiral rod 4 surrounds the conductive rod 3, occupying a smaller space to increase the cross-sectional area of ​​the conductive rod 3. The larger the cross-sectional area of ​​the conductor, the smaller the resistance per unit length, so the impedance will also be reduced accordingly. At the same time, the longer the length of the conductor, the greater its impedance. The wire is wound and fixed on the spiral rod 4 and can also reduce the distance from the pin terminal 2 to the wire.

[0024] The conductive sheet 21 , the conductive block 22 , and the spiral rod 4 are all made of metal with high electrical conductivity. The higher the electrical conductivity of the conductor, the smaller its impedance.

[0025] Working principle: When the utility model is in use, the conductive rod 3 is connected to the socket housing 1 through the fixing ring 5. After the spiral rod 4 is installed and fixed, the wire is wound and fixed on the spiral rod 4. The connector plug and the socket housing 1 are positioned and plugged through the docking groove 12, the card groove 13, and the U-shaped positioning groove 14. After power is turned on, the current is transmitted to the clip terminal and the connector plug through the conductive sheet 21 and the conductive block 22. Since the conductive sheet 21 and the conductive block 22 are made of metal with high conductivity, the resistance can be minimized when the contact area is small. The spiral rod 4 surrounds the conductive rod 3, occupying a small space to increase the cross-sectional area of ​​the conductive rod 3 and reduce the resistance. At the same time, the wire is wound and fixed on the spiral rod 4, which can also reduce the distance from the pin terminal 2 to the wire and reduce the impedance.
