[0039] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0040] On the one hand, combined with Figure 1 , 2 As shown, this embodiment provides a connector, which includes: a housing assembly 1 and a terminal assembly 2.

[0041] The terminal assembly 2 is located in the housing assembly 1 ; the terminal assembly 2 includes at least one conductive terminal 21 and a fixing member 22 ; at least one conductive terminal 21 is connected to the fixing member 22 , and the fixing member 22 is connected to the housing assembly 1 .

[0042] In the connector provided in this embodiment, the terminal assembly 2 is located in the shell assembly 1, and the terminal assembly 2 includes at least one conductive terminal 21 and a fixing member 22. The conductive terminal 21 is fixedly arranged on the fixing member 22, and the fixing member 22 is fixedly connected to the shell assembly 1, so as to realize the fixation of the conductive terminal 21 in the shell assembly 1, so that the conductive terminal 21 can omit the original clamping structure, the surface of the conductive terminal 21 has fewer mutation structures, and the cross-sectional characteristics of the conductive terminal 21 are optimized, which is beneficial to improving the SI (Signal Integrity) characteristics of the conductive terminal 21.

[0043] Signal integrity is an important concept in electronics and electrical engineering, especially in high-speed digital and analog circuit design. Signal integrity is mainly concerned with whether the shape and timing characteristics of the signal can be accurately and reliably maintained when transmitting in the circuit. Generally speaking, the SI characteristics of a conductor with a uniform cross-sectional shape are better than the SI characteristics of a conductor with an uneven cross-sectional shape. The reason is that when the cross-sectional shape is uneven or there is a sudden change in the cross-sectional shape, the impedance of the conductor will suddenly change, causing the signal to be subject to greater reflection interference and cause signal distortion.

[0044] In the conventional solution, the conductive terminal 21 usually needs to be designed with a concave and convex snap-fit ​​structure on the surface, and the snap-fit ​​structure is used to realize snap-fit ​​connection with the housing assembly 1. These snap-fit ​​structures cause a sudden change in the cross-sectional shape of the conductive terminal 21, which causes a great loss in the SI characteristics of the conductive terminal 21. Therefore, in the connector of this embodiment, the conductive terminal 21 is wrapped and fixed by the fixing member 22, and then the conductive terminal 21 is fixed in the housing assembly 1, so that the conductive terminal 21 does not need to be arranged with a snap-fit ​​structure, and the cross-sectional shape of the conductive terminal 21 tends to be uniform, thereby greatly improving the SI characteristics of the conductive terminal 21.

[0045] Combination Figure 3 , 4 As shown, in some embodiments, a first clamping structure 11 is provided on the inner wall of the housing assembly 1, a second clamping structure 221 is provided on the fixing member 22, and the first clamping structure 11 and the second clamping structure 221 are clamped and connected.

[0046] The first clamping structure 11 and the second clamping structure 221 can realize the clamping connection between the fixing member 22 and the inner wall of the housing assembly 1 , thereby realizing the connection between the conductive terminal 21 and the housing assembly 1 .

[0047] Exemplarily, one of the first clamping structure 11 and the second clamping structure 221 is a recessed clamping groove, and one of the first clamping structure 11 and the second clamping structure 221 is a protruding clamping block.

[0048] In another exemplary embodiment, the first clip structure 11 is located on the inner wall of the shell assembly 1 along the thickness direction, the position of the second clip structure 221 on the fixing member 22 corresponds to the position of the first clip structure 11, and the first clip structure 11 and the second clip structure 221 are clip-connected one-to-one.

[0049] Combination Figure 5 , 6 As shown, in some embodiments, at least one concave-convex portion 211 is disposed on the surface of the conductive terminal 21 , and the conductive terminal 21 is connected to the fixing member 22 by injection molding via the at least one concave-convex portion 211 .

[0050] By using at least one concave-convex portion 211 on the surface of the conductive terminal 21, the injection molding connection effect of the fixing member 22 and the conductive terminal 21 is better and the connection strength is high. Exemplarily, the size of the protrusion or depression of the concave-convex portion 211 is less than or equal to one fifth of the cross-sectional size of the conductive terminal 21, thereby reducing the degree of cross-sectional mutation of the conductive terminal 21 and reducing the influence of the concave-convex portion 211 on the SI characteristics of the conductive terminal 21.

[0051] Combination Figure 3 As shown, in some embodiments, there are multiple conductive terminals 21 , and the multiple conductive terminals 21 are arranged in parallel in the housing assembly 1 , and the multiple conductive terminals 21 are spaced apart from each other.

[0052] By utilizing the multiple conductive terminals 21 arranged in parallel, the connector can achieve the connection of multiple electrical signals, thereby improving the electrical signal connection performance of the connector.

[0053] When there are multiple conductive terminals 21, multiple conductive terminals 21 are arranged in parallel. The number of fixing members 22 can be one or more. When there is one fixing member 22, multiple conductive terminals 21 can be connected to the one fixing member 22 at the same time, and then fixed in the housing assembly 1 through the one fixing member 22. When there are multiple fixing members 22, each fixing member 22 can fix one or more conductive terminals 21, and then multiple fixing members 22 are fixed in parallel in the housing assembly 1.

[0054] By using a plurality of fixing members 22 to cover a plurality of conductive terminals 21 one by one and then arrange them in parallel, liquid can be prevented from invading between adjacent conductive terminals 21 , which is beneficial to improving the liquid ingress protection capability of the connector.

[0055] Combination Figure 5 , 6 As shown, in some embodiments, the conductive terminal 21 has a contact end 2101 and a connection end 2102 , and the fixing member 22 is connected between the contact end 2101 and the connection end 2102 .

[0056] Through the above arrangement, the contact end 2101 and the connection end 2102 of the conductive terminal 21 are respectively exposed outside the fixing member 22 , thereby facilitating the electrical connection between the two ends of the conductive terminal 21 .

[0057] The connector includes a plug-in end and a welding end, wherein the contact end 2101 of the conductive terminal 21 corresponds to the plug-in end, which can make contact and electrically connect with another connector when the connector is plugged in; the connection end 2102 of the conductive terminal 21 corresponds to the welding end, which can be welded and electrically connected with the conductor in the wiring harness or the plated circuit on the circuit board when the connector is welded and connected with the wiring harness or the circuit board.

[0059] In this embodiment, the assembly holes 12 in the housing assembly 1 can allow the conductive terminals 21 to be fixedly arranged according to the target posture and target position, so that they can serve as transmission lines for target electrical signals. When multiple conductive terminals 21 are respectively inserted into their respective assembly holes 12, the conductive terminals 21 are evenly and neatly arranged in the housing assembly 1, and adjacent conductive terminals 21 have good insulation.

[0061] Through the above arrangement, the metal shell 13 is sleeved on the outside of the insulating shell 14, which can enhance the structural strength of the shell assembly 1, protect the internal conductive terminals 21, and provide a common grounding path for the connector, thereby improving the connector's anti-electromagnetic interference capability.

[0062] Combination Figure 2 , 7 As shown, in some embodiments, the connector further includes a conductive connector 3 , which is located between the metal shell 13 and the insulating shell 14 , and at least a portion of the conductive connector 3 extends into the insulating shell 14 .

[0063] Among them, one end of the conductive connector 3 is electrically connected to the metal shell 13, and the other end extends into the insulating shell 14, and can be electrically connected to the metal shell 13 of another connector plugged into the insulating shell 14, thereby realizing the grounding connection of the two connectors and improving the anti-electromagnetic interference capability of the two connectors.

[0064] In some possible implementations, a second avoidance groove 16 is provided outside the insulating shell 14, and the conductive connector 3 is placed in the second avoidance groove 16, so that the conductive connector 3 does not need to occupy the space of the metal shell 13, and the appearance of the metal shell 13 remains smooth and complete.

[0065] Combination Figure 2 , 7As shown, in some embodiments, the connector further includes a hook member 4, which is located between the metal shell 13 and the insulating shell 14, and at least a portion of the hook member 4 extends into the insulating shell 14. The hook member 4 arranged between the metal shell 13 and the insulating shell 14 can be used to clamp another connector plugged into the connector, provide a certain clamping force to the other connector, and ensure the stability of the plug connection.

[0066] In some possible implementations, combined with Figure 4 As shown, the insulating shell 14 is provided with a first avoidance groove 15, and the hook member 4 is located in the first avoidance groove 15, so that the hook member 4 does not need to occupy the space of the metal shell 13, and the appearance of the metal shell 13 remains smooth and complete.

[0067] In some possible implementations, combined with Figure 2 , 7 As shown, the connector provided in this embodiment is a female connector, and the internal cavity of the insulating housing 14 is used to accommodate the male connector. Among them, the contact end 2101 of the conductive terminal 21 is a bayonet structure arranged up and down, and the tongue of the male connector is inserted into the bayonet structure of the contact end 2101.
