Description
Technical Field
[0001] This application relates to the technical field of connectors, and in particular, to a female connector and a connector assembly. Background Art
[0002] With the rapid development of current communication technologies, the data processing rate has been continuously increasing, and the requirements for the transmission rate and related performance of connectors have also increased accordingly. To improve the performance of connectors, methods such as shortening the shielding return path, using a fully enclosed shielding structure, and increasing the shielding return points are usually adopted. In current connectors, the shielding return area generally conducts return current in the contact area inside the connector. The return path in the contact area is too long compared to the return path on the mating surface, and it no longer meets the shielding requirements for high transmission rates. However, when designing a return structure on the mating surface, the space is very narrow, and there are significant problems with the reliability of the symmetric double-contact return contact structure designed on a single layer.
[0003] Therefore, it is necessary to improve the existing technology. Summary of the Invention
[0004] The present invention aims to at least solve one of the technical problems existing in the prior art, and provides a female connector and a connector assembly.
[0005] According to one aspect of the present application, the present application provides a female connector, including: a base assembly having a mating surface, and shielding holes provided on the mating surface; and a shielding assembly including two shielding layers, each of the shielding layers being sequentially stacked on the mating surface. The shielding layer includes a main body portion and a connecting arm. The main body portion is provided with an avoidance groove, and the connecting arm is connected to the groove wall of the avoidance groove and extends into the shielding hole. The connecting arms of each shielding layer are oppositely arranged in the shielding hole to cooperate with and clamp a pin.
[0006] Further, the female connector has a first direction and a reference plane that are perpendicular to each other. The connecting arms of each shielding layer are oppositely arranged in the shielding hole along the first direction; in the shielding hole, the projections of the ends of each connecting arm far from the main body portion to which it is connected on the reference plane overlap.
[0007] Optionally, the female connector has a second direction, and the second direction is parallel to the reference plane and the mating surface; the connecting arms have the same length in the second direction.
[0008] Further, in the avoidance groove, two of the connecting arms are connected at intervals along the second direction, and the connecting arms in the shielding hole are pairwise opposite.
[0009] Further, the female connector has a third direction, and the third direction is perpendicular to the shielding layer; the connecting arm and the contact of the pin are spaced apart in the third direction.

[0011] Further, at least one top block is provided in the shielding hole. When the pin is inserted into the shielding hole, the top block abuts against the second extending portion.
[0012] Further, the female terminal connector has a third direction perpendicular to the shielding layer; the length of the shielding layer in the third direction is 0.04 mm - 0.06 mm.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.
[0029] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0030] The following will elaborate on the female terminal connector and connector assembly in the present application in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. And in the following embodiments, each embodiment has its own emphasis. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
[0031] In the prior art, there are relatively large problems with the reliability of the symmetric double-contact reflux contact structure designed on a single layer. There will be situations such as excessive insertion and extraction force during male-female mating, difficult insertion and extraction, and the phenomenon of the male terminal pin getting stuck, plastic deformation of the reflux contact structure, risk of contact reliability, and low durability and easy fracture of the contact reflux structure.
[0032] The embodiments of the present application provide a female terminal connector and a connector assembly, which can solve the technical problem of poor connection reliability and unfavorable insertion and extraction in the prior art, and will be described in detail respectively.
[0033] Please refer to Figure 1 and Figure 7 , Figure 1 is a schematic diagram of a female terminal connector provided by an embodiment of the present application, Figure 7 is an exploded schematic diagram of a female terminal connector provided by an embodiment of the present application.
[0034] In one embodiment, the above-mentioned female terminal connector includes a base assembly 10 and a shielding assembly 20. The base assembly 10 has a mating surface 11, which is the contact surface when the female terminal connector and the male terminal connector cooperate with each other. A plurality of shielding holes 12 are provided on the mating surface 11, and the pins 30 of the male terminal connector are inserted into the shielding holes 12; the shielding assembly 20 includes two shielding layers 21. The shielding layer 21 includes a main body portion 211 and an avoidance groove 213 provided on the main body portion 211. A connecting arm 212 is connected to the groove wall of the avoidance groove 213, and the free end of the connecting arm 212 extends into the shielding hole 12. The two shielding layers 21 are sequentially stacked on the mating surface 11, and the connecting arms 212 on the two shielding layers 21 are arranged opposite to each other in the shielding hole 12. The oppositely arranged connecting arms 212 are used to clamp the pin 30 to ensure the stability of the pin 30. In this embodiment, two connecting arms 212 are provided in the same shielding hole 12, that is, one connecting arm 212 is provided on one shielding layer 21, and two oppositely arranged connecting arms 212 are formed after stacking and installation to clamp the pin 30, as Figure 3 ( Figure 3 is Figure 2 an enlarged view of an embodiment at B in
[0035] It should be noted that the above avoidance groove 213 leaves a traveling space for the insertion and extraction operation of the pin 30. Therefore, the above avoidance groove 213 at least partially covers the shielding hole 12. In this embodiment, the area of the avoidance groove 213 is larger than the area of the shielding hole 12. As Figure 2 (Yes Figure 1 as shown in the top view of an embodiment), in other embodiments, it can also be set in other forms, which will not be elaborated here; in the above two shielding layers 21, the shielding layer 21 in contact with the mating surface 11 is called the shielding layer 21 arranged at the bottom in this embodiment, and the other shielding layer 21 is the shielding layer 21 arranged at the top. In other embodiments, it can also be distinguished in other forms, only for the convenience of description. When the top shielding layer 21 is attached to the bottom shielding layer 21, the connecting arm 212 of the top shielding layer 21 extends into the shielding hole 12 after passing through the avoidance groove 213 on the bottom shielding layer 21. In other embodiments, other grooves or holes can also be provided on the main body portion 211 for the installation of the connecting arm 212 of the top shielding layer 21.
[0036] In addition, in this embodiment, the above female connector has a first direction (such as Figure 2 the direction Y shown in Figure 2 below), the same hereinafter) and a reference plane (such as Figure 2 the α shown in Figure 6 ( Figure 6 Yes Figure 5As shown by H in the enlarged view of an embodiment at position C (Figure [not shown]), that is, by adjusting the distance between the two oppositely arranged connecting arms 212 within the same shielding hole 12, it is possible to ensure smooth insertion and extraction of the pin 30, without problems such as excessive insertion / extraction force, difficult insertion / extraction, or pin jamming, and there is a large adjustment space for the spring height. In this embodiment, the above-mentioned avoidance groove 213 is rectangular, with the first side (not marked in the figure) connected to the connecting arm 212, and the second side adjacent to the first side. In the prior art, when two connecting arms 212 are stamped on a single shielding layer 21, the two connecting arms 212 are respectively arranged on two first sides. In the first case, the parts of the two connecting arms 212 in contact with the pin 30 are misaligned. This misaligned setting can ensure the length of the connecting arm 212 in the first direction before bending, but is not conducive to the stability of the connection and the smooth progress of insertion and extraction. In the second case, the sum of the lengths of the two connecting arms 212 in the first direction before bending is equal to the second side, and the adjustment space for the spring height of the bent connecting arm 212 is relatively small. However, when the two connecting arms 212 of the present application are respectively arranged on two different shielding layers 21, the length of the connecting arm 212 in the first direction after stamping is equal to (or slightly less than) the length of the second side, and the adjustment space for the spring height is large. Moreover, being separately arranged on two shielding layers 21 can adjust the positions of the two connecting arms 212 to ensure that the orthographic projections of the ends of the connecting arms 212 far from the main body part 211 they are connected to on the above-mentioned reference plane overlap, ensuring the contact area between the connecting arm 212 and the pin 30 and improving the reliability of the connection. In this embodiment, the above-mentioned orthographic projection can be completely coincident, as shown in Figure 3 shown; and in this embodiment, the lengths of the connecting arms 212 in the second direction are the same, and the length of the connecting arm 212 in the second direction can be adjusted according to the size of the pin 30 to ensure sufficient contact with the pin 30 and improve the reliability of the connection.
[0037] Further, in other embodiments, two connecting arms 212 are spaced apart in the above-mentioned second direction, as shown in Figure 4 ( Figure 4 is Figure 2 the enlarged view of another embodiment at position B in [Figure not shown]), the connecting arms 212 within the above-mentioned shielding hole 12 are pairwise opposite, having four contacts with the pin 30, improving the reliability of the connection and being applicable to different styles of pins 30. In other embodiments, there can also be other forms of settings, which will not be elaborated here.
[0038] Refer to Figure 5 and Figure 6 , Figure 5 is Figure 2 the cross-sectional view of an embodiment at A-A in [Figure not shown].
[0039] In one embodiment, the above-mentioned female connector further has a third direction (such as Figure 5As shown in the direction Z (the same below), the third direction is perpendicular to the above-mentioned shielding layer 21. The contact points of the connecting arms 212 and the pins 30 are spaced in the above-mentioned third direction. When spaced, the acting forces of the two connecting arms 212 on the pins 30 are not on the same straight line (such as Figure 6 the forces F1 and F2 shown in the figure), and the acting forces will not cancel each other out. Therefore, the stability of the insertion of the pins 30 can be ensured.
[0040] Please continue to refer to Figure 6 , in an embodiment, the connecting arm 212 successively has a first bending portion 2121, a first extending portion 2122, a second bending portion 2123, and a second extending portion 2124 from the avoiding groove 213. The bending directions of the first bending portion 2121 and the second bending portion 2123 are the same, that is, the second bending portion 2123 abuts against the pin 30, and the second extending portion 2124 will not form a restriction on the pin 30, and there will be no phenomenon such as pin jamming that is not easy to insert and remove; in this embodiment, a top block 121 is provided in the shielding hole 12. In other embodiments, there can be multiple settings, which are determined according to actual use requirements and will not be elaborated here. When the pin 30 is inserted into the shielding hole 12, the top block 121 abuts against the second extending portion 2124, which can ensure the clamping of the connecting arm 212 to the pin 30 and ensure the stability of the connection. Even when the elasticity of the connecting arm 212 weakens or only one connecting arm 212 contacts the pin 30, good contact can be ensured and the reliability of the connection can be guaranteed.
[0041] Please continue to refer to Figure 3 , in an embodiment, the length of the shielding layer 21 in the above-mentioned third direction is 0.04 mm. In other embodiments, it can also be any value between 0.04 mm and 0.06 mm, not limited to this, and is determined according to actual requirements; and in this embodiment, a limiting block 111 is provided on the mating surface 11. The limiting block 111 extends in the third direction, and a notch 214 adapted to the limiting block 111 is provided on the shielding layer 21, which can limit the shielding layer 21 and facilitate the fixed installation of the shielding layer 21. Moreover, the length of the limiting block 111 in the third direction is less than the sum of the lengths of the two shielding layers 21 in the third direction, and it will not affect the mating use of the female connector and the male connector.
[0042] It should be noted that the installation method of the above-mentioned shielding layer 21 can be welding, thermal riveting, riveting, etc., and no specific limitation is made here.
[0043] On the other hand, the present application also relates to a connector combination, including any of the above-mentioned female connectors, and the connector combination further includes a male connector used in docking with the above-mentioned female connector.
[0044] The present application provides a female connector and a connector assembly. The female connector is provided with two different shielding layers laminated on the mating surface, and the connecting arms on the two shielding layers are oppositely arranged in the same shielding hole for clamping the pin. The connecting arms are separately arranged, and the distance between the two connecting arms can be adjusted by adjusting the spring height of the connecting arms, ensuring smooth insertion and extraction, avoiding excessive insertion and extraction force of the pin, difficult insertion and extraction, and jamming phenomenon, and avoiding the influence of plastic deformation of the connecting arms on the contact reliability, thereby improving the service life.
[0045] In various embodiments of the present application, if there is no special description and logical conflict, the terms or descriptions between different embodiments are consistent and can be referred to each other, and the technical features in different embodiments can be combined to form a new embodiment according to their internal logical relationship. In the present application, "at least one" means one or more, and "a plurality" means two or more.
[0046] It can be understood that in the embodiments of the present application, the various numerical numbers involved are only for the convenience of description and are not used to limit the scope of the embodiments of the present application.
