Description

Female connector, male connector and connector assembly

[0001] The present application claims priority to the Chinese patent application No. 202410729217.X, filed on June 06, 2024, and entitled "Female connector, male connector and connector assembly", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of circuit connection, in particular to a female connector, a male connector and a connector assembly. BACKGROUND

[0003] Connectors play an important role in circuit connection. The connector generally includes a male connector and a female connector, the male connector has an insertion terminal, and the female connector has a slot, the insertion terminal can be electrically connected with the slot, so that the circuit can be turned on. The existing slot is generally a straight slot, that is, the distance between each position of the inner wall of the slot and the insertion terminal is consistent when the female connector and the male connector are inserted.

[0004] Ideally, the insertion terminal can be completely inserted into the corresponding position in the slot and can be reliably electrically connected with the corresponding signal terminal in the slot, at this time, the signal transmission quality is good. However, there is also a situation that the insertion terminal cannot be inserted in place between the insertion terminal and the slot, that is, a part of the insertion terminal can be electrically connected with the signal terminal, while a part of the insertion terminal cannot be electrically connected with the signal terminal and is exposed in the slot. Although signal transmission can be achieved in this state, there is a large gap between the part of the insertion terminal not electrically connected with the signal terminal and the inner wall of the slot, and the gap is filled with air, which will cause impedance rise when air is used as a medium, reducing the signal transmission quality. SUMMARY

[0005] Therefore, the present application provides a female connector, a male connector and a connector assembly to solve the problem that the gap between the insertion terminal and the inner wall of the slot is too large when the female connector and the male connector are not inserted in place, and the air in the gap as a medium causes impedance rise.

[0006] In a first aspect, the present application provides a female connector, which includes a first needle seat, the first needle seat includes a first cavity and a second cavity, a first containing space is arranged in the first cavity, a second containing space is arranged in the second cavity, the height of the first containing space is less than the height of the second containing space along the thickness direction of the first needle seat, at least part of the inner wall of the first cavity and at least part of the inner wall of the second cavity are made of conductive material, and a signal terminal is arranged in the second cavity.

[0007] The female connector provided in the application can be plugged with a male connector, and the male connector includes a signal pin which can be inserted into the second cavity and electrically connected with the signal terminal. In the application, the caliber of the first cavity is inconsistent with the caliber of the second cavity. Specifically, along the thickness direction of the first needle seat, the height of the first accommodating space is smaller than the height of the second accommodating space. In the state that the signal pin is not completely plugged in place, the part of the signal pin located in the first accommodating space can have a relatively small gap with the inner wall of the first cavity, reducing the transmission of electromagnetic energy in the air at the gap, so that the influence of impedance rise caused by the signal pin not being completely plugged in place can be reduced.

[0008] In a possible design, the first needle seat includes a first shielding member and a second shielding member. Along the thickness direction of the first needle seat, the first shielding member and the second shielding member are arranged on opposite sides of the first needle seat, and at least part of the first shielding member constitutes the inner wall on one side of the first cavity and the second cavity, and at least part of the second shielding member constitutes the inner wall on the other side of the first cavity and the second cavity. The distance between the part of the first shielding member corresponding to the first cavity and the part of the second shielding member corresponding to the first cavity is H1, and the distance between the part of the first shielding member corresponding to the second cavity and the part of the second shielding member corresponding to the second cavity is H2, H1 < H2. Wherein, by designing the structural form of the first shielding member and the second shielding member, the size of the first accommodating space in the first cavity and the second accommodating space in the second cavity in the thickness direction of the first needle seat can be adjusted, that is, the height of the first accommodating space in the thickness direction of the first needle seat is smaller than the size of the second accommodating space in the thickness direction of the first needle seat. In the case that the signal pin is not completely plugged in place, the part of the signal pin located in the first accommodating space can have a relatively small gap with the inner wall of the first cavity, so that the influence of impedance rise caused by the signal pin not being completely plugged in place can be reduced.

[0009] In a possible design, the first shielding member includes a first shielding portion, a first transition portion, and a second shielding portion, two ends of the first transition portion are connected to the first shielding portion and the second shielding portion respectively, the first shielding portion and the second shielding portion are arranged in parallel, the first transition portion is arranged obliquely between the first shielding portion and the second shielding portion, at least part of the first shielding portion forms an inner wall of the first cavity, and at least part of the second shielding portion forms an inner wall of the second cavity; and / or the second shielding member includes a third shielding portion, a second transition portion, and a fourth shielding portion, two ends of the second transition portion are connected to the third shielding portion and the fourth shielding portion respectively, the third shielding portion and the fourth shielding portion are arranged in parallel, the second transition portion is arranged obliquely between the third shielding portion and the fourth shielding portion, at least part of the third shielding portion forms an inner wall of the first cavity, and at least part of the fourth shielding portion forms an inner wall of the second cavity.

[0010] The first shielding portion can be an integrally formed metal plate structure, and the corresponding first shielding portion, second shielding portion and first transition portion can be formed through bending or other processes. By bending at the connection positions of the first transition portion and the first shielding portion and the second shielding portion, the first shielding portion and the second shielding portion can be located in two mutually parallel planes, forming a stepped shape. After the first shielding member and the second shielding member are assembled into the first needle seat, the size of the first accommodating space in the thickness direction of the first needle seat can be smaller than the size of the second accommodating space in the thickness direction of the first needle seat. The second shielding member can also have a similar structure to the first shielding member. By bending at the connection positions of the second transition portion and the third shielding portion and the fourth shielding portion, the third shielding portion and the fourth shielding portion can be located in two mutually parallel planes, forming a stepped shape, so that the size of the first accommodating space in the thickness direction of the first needle seat can also be smaller than the size of the second accommodating space in the thickness direction of the first needle seat.

[0011] In a possible design, the first shielding member is integrally formed, and the second shielding member is integrally formed, which can facilitate processing and manufacturing. The first shielding member and the second shielding member each have a large area, and the first shielding member and the second shielding member can be installed on both sides of the first needle seat as a whole and cover all the transmission channels on one first needle seat at the same time, thereby facilitating assembly and ensuring the consistency of the shielding effect of the first shielding member and the second shielding member at each transmission port.

[0012] In a possible design, the first needle seat further includes an insulating member and a plurality of third shielding members connected to the insulating member and spaced apart along the length direction of the insulating member. At least part of the third shielding members is located on one side of the insulating member along the width direction of the insulating member, and at least another part of the third shielding members is located on the other side of the insulating member. The first cavity and the second cavity are formed between adjacent two third shielding members, the insulating member, the first shielding member, and the second shielding member. The third shielding members and the insulating member can be perpendicular to each other, and a cross shape can be formed between each third shielding member and the insulating member. The first cavity and the second cavity can be separated by the insulating member, that is, the first cavity can be formed between parts on the same side of the insulating member of adjacent two third shielding members, the first shielding member, and the second shielding member, and the second cavity can be formed between parts on the same other side of the insulating member of adjacent two third shielding members, the first shielding member, and the second shielding member. In this way, the dense arrangement of multiple transmission ports can be achieved by cooperation of the insulating member and the third shielding members, and the high-density and high-bandwidth characteristics of the female connector are enhanced. In addition, the first cavity and the second cavity can be electromagnetically shielded in the circumferential direction by cooperation of the first shielding member, the second shielding member, and the third shielding member, and the problem of electromagnetic energy crosstalk can be effectively avoided. Meanwhile, the first cavity and the second cavity can be closed in the plugged state of the female connector and the male connector, and the electromagnetic shielding effect can be further enhanced.

[0013] In a possible design, the insulating member is provided with a through hole at a position between the first cavity and the second cavity, the first cavity and the second cavity are communicated through the through hole, and the signal pin is inserted into the second cavity through the through hole. The through hole can be directly formed in the manufacturing process of the insulating member, and a plurality of through holes can be provided. Each signal pin can be matched with a corresponding through hole, that is, the signal pin can be electrically connected to the signal terminal in the second cavity after passing through the through hole.

[0014] In a possible design, the signal terminal includes a first spring piece and a second spring piece arranged along the thickness direction of the first needle seat. The first spring piece includes a first clamping portion, and the second spring piece includes a second clamping portion. A space is maintained between the first clamping portion and the second clamping portion. At least part of the first spring piece away from the first clamping portion is electrically connected to at least part of the second spring piece away from the second clamping portion. The first spring piece and the second spring piece can be thin sheet structures made of metal material. The signal pin can be inserted between the first spring piece and the second spring piece and can be reliably abutted with the first spring piece and the second spring piece, thereby facilitating the connection between the signal pin and the signal terminal.

[0015] In a possible design, the first elastic sheet and the second elastic sheet are symmetrically arranged along the thickness direction of the first needle seat. That is, the first elastic sheet and the second elastic sheet can have the same structure, and by symmetrically arranging the first elastic sheet and the second elastic sheet, the signals on the first elastic sheet and the second elastic sheet can have the same transmission path, so that the transmission time difference between the signals on the first elastic sheet and the second elastic sheet can be avoided, thereby ensuring high signal transmission quality.

[0016] In a possible design, the distance between at least partial positions of the first clamping part and the second clamping part is less than the thickness of the signal pin in the thickness direction of the first needle seat. Thus, when the signal pin is inserted between the first clamping part and the second clamping part, the signal pin can push the first clamping part and the second clamping part away from each other, and the first clamping part and the second clamping part can be elastically deformed, and the elastic force generated by the elastic deformation can ensure that the first clamping part and the second clamping part can reliably abut against the signal pin, thereby ensuring effective electrical connection.

[0017] In a possible design, at least partial positions of the signal terminal are located in the first cavity, and at least partial positions of the signal terminal are located in the second cavity, or the signal terminal is entirely located in the second cavity. Thus, the arrangement of the signal terminal has strong flexibility, and can be designed according to the structure of the female connector.

In the state that the signal pin is not completely plugged in place, the part of the signal pin located in the first accommodating space can have a small gap with the inner wall of the first cavity, the transmission of electromagnetic energy in the air at the gap is reduced, and thus the influence of the impedance rise caused by the signal pin not being completely plugged in place can be reduced.

[0020] In a possible design, the second needle seat comprises a main body, a fourth shielding member and a fifth shielding member, the fourth shielding member and the fifth shielding member are connected to two sides of the main body in the thickness direction respectively.

And / or, along the arrangement direction of the plurality of third protruding parts, second flanges are arranged on the edges of opposite sides of the third protruding parts, and the two second flanges shield the two sides of the first protruding part respectively. The cross section of the second protruding part with the first flange is in the shape of “U”, which can form a half-enclosed shape for the first protruding part, so that the second protruding part can shield the electromagnetic energy of the signal pin in multiple directions and prevent crosstalk. Similarly, the cross section of the fourth protruding part with the second flange is in the shape of “U”, which can form a half-enclosed shape for the first protruding part, so that the third protruding part can shield the electromagnetic energy of the signal pin in multiple directions and prevent crosstalk.

DETAILED DESCRIPTION

[0051] In order to better understand the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0052] It should be clear that the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0053] The terms used in the embodiments of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0054] It should be understood that the term "and / or" used herein is merely an association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " herein generally represents that the front and rear associated objects are in an "or" relationship.

[0055] In the description of the present application, unless otherwise explicitly specified and limited, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" means two or more; the terms "connection", "fixation" and the like should be understood in a broad sense, for example, "connection" can be fixed connection, or detachable connection, or integrally connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0056] The connector plays an important role in circuit connection, and the connector can connect two active devices for transmitting current or signal. The connector generally includes a male connector and a female connector, the male connector can include an insertion terminal, and the female connector has a slot, and the slot can be provided with a signal terminal for cooperating with the insertion terminal, when the male connector and the female connector are inserted and matched, the insertion terminal can be inserted into the slot and can be electrically connected with the signal terminal, so that the conduction of the circuit can be realized. The existing slot is generally a straight slot, that is, the caliber of the slot is uniform at each place in the extension direction of the slot, and the distance between each position of the inner wall of the slot and the insertion terminal is consistent in the inserted and matched state of the female connector and the male connector.

[0057] Ideally, the insertion terminal can be completely inserted into the corresponding position in the slot and can be reliably electrically connected with the corresponding signal terminal in the slot, at this time, the signal transmission quality is good.

Although signal transmission can be realized in this state, there is a large gap between the part of the insertion terminal that is not electrically connected with the signal terminal and the inner wall of the slot, and the gap is filled with air, which will cause the impedance to rise significantly when air is used as a medium, and the signal transmission quality is reduced.

Such a transmission port 1A can be provided with multiple on the first needle seat 1, and the multiple transmission ports 1A can be arrayed. In other embodiments, the first needle seat 1 can include only one transmission port 1A, and multiple such independent transmission ports 1A can be arrayed.

Such a transmission end can also be provided with multiple, and the multiple transmission ends can be arranged in an array. Each transmission end can be plugged with a corresponding transmission port 1A to achieve multi-link signal transmission. In other embodiments, the second needle seat 2 can only include one of the foregoing transmission ends, and multiple independent transmission ends can be arranged in an array, which is not limited in the embodiment. In the female connector 10, FIG. 8 is a sectional view of the first needle seat 1 provided in an embodiment of the present application. Referring to FIG. 8, the first cavity 11 is located outside the second cavity 12, and the signal terminal 13 is arranged in the second cavity 12. When the female connector 10 and the male connector 20 are plugged, at least part of the signal pin 21 can first pass through the first cavity 11 and then be inserted into the second cavity 12, and can be electrically connected with the signal terminal 13 in the second cavity 12. In an embodiment, the signal terminal 13 can be entirely located in the second cavity 12. In an embodiment, at least part of the signal terminal 13 can be located in the first cavity 11, and at least part of the signal terminal 13 can be located in the second cavity 12, that is, the signal terminal 13 can penetrate the second cavity 12, and at least part of the end portion of the signal terminal 13 can extend into the first cavity 11.

Referring to Figs. 9 and 10, in the ideal state that the signal pin 21 is fully inserted into the position, that is, the insertion depth of the signal pin 21 in the first needle seat 1 can reach the preset depth, there is no part of the signal pin 21 located in the first cavity 11, and the signal can be transmitted on the signal pin 21 and the signal terminal 13, so that good high-speed signal transmission quality can be obtained.

[0064] Fig. 11 is a schematic diagram of the female connector 10 and the male connector 20 not being completely matched to the position provided by the embodiment of the application, and Fig. 12 is a partial enlarged view of B in Fig. 11. Referring to Figs. 11 and 12, in the state that the signal pin 21 is not completely inserted into the position, a part of the signal pin 21 can be inserted into the second cavity 12 and can maintain effective electrical connection with the signal terminal 13, while, due to the signal pin 21 not being completely inserted into the position, a part of the signal pin 21 (referring to the area P marked by the dashed line frame in Fig. 12) is located in the first cavity 11, which causes the part of the signal pin 21 located in the second cavity 12 to be smaller, that is, the coupling area of the signal pin 21 and the signal terminal 13 is reduced, and further causes the impedance to be increased, which affects the signal transmission quality. Meanwhile, there is a gap between the part in the first cavity 11 and the inner wall of the first cavity 11, and the gap is filled with air, that is, the part of the signal pin 21 located in the first cavity 11 will scatter electromagnetic energy into the air in the gap and cannot be transmitted through the cooperation of the signal pin 21 and the signal terminal 13, which also causes the impedance to be increased.

[0065] Therefore, in the embodiment, the first cavity 11 can be provided with a first accommodating space, and the second cavity 12 can be provided with a second accommodating space. Wherein, the size of the second accommodating space in the thickness direction Z of the first needle seat 1 is a common size in the connector, and the second accommodating space is used for accommodating the signal terminal 13. Generally, the transmission port 1A in the existing female connector 10 has a consistent caliber in the extension direction thereof, and the caliber can be similar to the caliber of the second cavity 12 in the embodiment.

[0066] In the embodiment, referring to Fig. 12, the caliber of the first cavity 11 is inconsistent with the caliber of the second cavity 12, and exemplarily, the height of the first accommodating space is smaller than the height of the second accommodating space along the thickness direction Z of the first needle seat 1. In the state that the signal pin 21 is not completely inserted into the position, the part of the signal pin 21 located in the first accommodating space can have a smaller gap with the inner wall of the first cavity 11, which reduces the transmission of electromagnetic energy in the air in the gap, so that the influence of the impedance increase caused by the signal pin 21 not being completely inserted into the position can be reduced.

[0067] In an embodiment, FIG. 13 is an exploded view of a first needle seat 1 provided by the embodiments of the present application. Referring to FIG. 13 and FIG. 8, the first needle seat 1 includes a first shielding member 14 and a second shielding member 15. Along the thickness direction Z of the first needle seat 1, the first shielding member 14 and the second shielding member 15 are arranged on opposite sides of the first needle seat 1. At least part of the first shielding member 14 constitutes the inner wall of one side of the first cavity 11 and the second cavity 12, and at least part of the second shielding member 15 constitutes the inner wall of the other side of the first cavity 11 and the second cavity 12. The first shielding member 14 and the second shielding member 15 can be made of a metal material, such as aluminum, copper, etc. The first shielding member 14 and the second shielding member 15 made of a metal material have an electromagnetic shielding effect, which can attract the scattered electromagnetic energy on the signal pins 21 and the signal terminals 13, thereby avoiding interference of the scattered electromagnetic energy with the signals transmitted in other signal pins 21 and signal terminals 13 nearby.

[0068] Referring to FIG. 12, the distance between the part of the first shielding member 14 corresponding to the first cavity 11 and the part of the second shielding member 15 corresponding to the first cavity 11 is H1, and the distance between the part of the first shielding member 14 corresponding to the second cavity 12 and the part of the second shielding member 15 corresponding to the second cavity 12 is H2, H1 < H2. By designing the structure of the first shielding member 14 and the second shielding member 15, the size of the first accommodating space in the first cavity 11 and the second accommodating space in the second cavity 12 in the thickness direction Z of the first needle seat 1 can be adjusted, i.e. the height of the first accommodating space in the thickness direction Z of the first needle seat 1 is smaller than the size of the second accommodating space in the thickness direction Z of the first needle seat 1. In the case where the signal pins 21 are not completely inserted in place, the part of the signal pins 21 located in the first accommodating space can have a relatively small gap with the inner wall of the first cavity 11, thereby reducing the influence of impedance rise caused by incomplete insertion.

[0069] In an embodiment, the first shielding member 14 and the second shielding member 15 can be integrally formed, which can facilitate processing and manufacturing. The first shielding member 14 and the second shielding member 15 each have a large area, and can be integrally installed on the two sides of the first needle seat 1 and simultaneously cover all the transmission channels on one first needle seat 1, thereby facilitating assembly and ensuring consistency of the shielding effect of the first shielding member 14 and the second shielding member 15 at each transmission port 1A.

[0070] In some other embodiments, the first shield 14 and the second shield 15 can also respectively include multiple parts, at least one part can serve as a sidewall of the first cavity 11, and at least another part can serve as a sidewall of the second cavity 12, the multiple parts can be independently manufactured and assembled, and the present embodiment does not limit this.

[0071] In an embodiment, FIG. 14 is a schematic view of the cooperation of the first shield 14 and the second shield 15 provided by the present embodiment, referring to FIG. 14, the first shield 14 can include a first shielding part 141, a first transition part 143, and a second shielding part 142, two ends of the first transition part 143 are respectively connected to the first shielding part 141 and the second shielding part 142, the first shielding part 141 and the second shielding part 142 are arranged in parallel, the first transition part 143 is arranged obliquely between the first shielding part 141 and the second shielding part 142, at least part of the first shielding part 141 constitutes an inner wall of the first cavity 11, and at least part of the second shielding part 142 constitutes an inner wall of the second cavity 12. Among them, the first shielding part 141 can be an integrally formed metal plate structure, the corresponding first shielding part 141, second shielding part 142 and first transition part 143 can be formed by bending process, by bending at the connection position of the first transition part 143 and the first shielding part 141 and the second shielding part 142, the first shielding part 141 and the second shielding part 142 can be located in two parallel planes, forming a stepped shape, after the first shield 14 and the second shield 15 are assembled into the first needle seat 1, the size of the first accommodating space in the thickness direction Z of the first needle seat 1 can be smaller than the size of the second accommodating space in the thickness direction Z of the first needle seat 1.

[0072] In an embodiment, referring to FIG. 14, the second shield 15 can also have a similar structure to the first shield 14. The second shield 15 can include a third shielding part 151, a second transition part 153, and a fourth shielding part 152, two ends of the second transition part 153 are respectively connected to the third shielding part 151 and the fourth shielding part 152, the third shielding part 151 and the fourth shielding part 152 are arranged in parallel, the second transition part 153 is arranged obliquely between the third shielding part 151 and the fourth shielding part 152, at least part of the third shielding part 151 constitutes an inner wall of the first cavity 11, and at least part of the fourth shielding part 152 constitutes an inner wall of the second cavity 12. Among them, by bending at the connection position of the second transition part 153 and the third shielding part 151 and the fourth shielding part 152, the third shielding part 151 and the fourth shielding part 152 can be located in two parallel planes, forming a stepped shape, so that the size of the first accommodating space in the thickness direction Z of the first needle seat 1 can be smaller than the size of the second accommodating space in the thickness direction Z of the first needle seat 1.

[0073] That is, only one of the first shield 14 or the second shield 15 can have the stepped structure described above, and the other can be a flat plate structure. Alternatively, both the first shield 14 and the second shield 15 can have the stepped structure described above. These structures can all achieve a size of the first accommodating space in the thickness direction Z of the first needle seat 1 being smaller than a size of the second accommodating space in the thickness direction Z of the first needle seat 1.

[0074] In an embodiment, for ease of illustration, the first needle seat 1 can be defined as having a first direction X and a second direction Y, the first direction X, the second direction Y, and the thickness direction Z of the first needle seat 1 being perpendicular to each other. In an embodiment, FIG. 15 is a structural schematic diagram of the insulating member 16 provided by an embodiment of the present application in one viewing angle. Referring to FIG. 15, the first needle seat 1 further includes the insulating member 16 and a plurality of third shields 17, the third shields 17 being connected to the insulating member 16 and being spaced apart along the length direction (the first direction X) of the insulating member 16. The third shields 17 can be made of a metal conductive material, such as aluminum, copper, etc. The third shields 17 made of metal material have a shielding effect on electromagnetic energy, i.e., can attract electromagnetic energy scattered by the signal pins 21 and the signal terminals 13, avoiding interference of the scattered electromagnetic energy on signals transmitted by the signal pins 21 and the signal terminals 13 in other transmission channels nearby.

[0075] Referring to FIG. 15, at least part of the third shield 17 is located on one side of the insulating member 16 along the width direction (the second direction Y) of the insulating member 16, and at least another part of the third shield 17 is located on the other side of the insulating member 16. In an embodiment, the third shield 17 and the insulating member 16 can be arranged perpendicular to each other, and a “cross” shape can be formed between each third shield 17 and the insulating member 16. The first cavity 11 and the second cavity 12 can be separated by the insulating member 16, i.e., a part of the first shield 14 and the second shield 15 and the adjacent two third shields 17 on the same side of the insulating member 16 can constitute the first cavity 11, and a part of the first shield 14 and the second shield 15 and the adjacent two third shields 17 on the same other side of the insulating member 16 can constitute the second cavity 12. Thus, through cooperation of the insulating member 16 and the third shield 17, dense arrangement of the plurality of transmission ports 1A can be achieved, and high-density and high-bandwidth characteristics of the female connector 10 are enhanced. In addition, through cooperation of the first shield 14, the second shield 15, and the third shield 17, electromagnetic shielding of the first cavity 11 and the second cavity 12 in the circumferential direction can be achieved, which can effectively avoid electromagnetic energy crosstalk. At the same time, in the plugged state of the female connector 10 and the male connector 20, the first cavity 11 and the second cavity 12 can also be closed, so that the electromagnetic shielding effect can be further enhanced.

[0076] In an embodiment, the insulating member 16 can be made of plastic material and can have a columnar structure, which is both insulating and stable, and can reliably support. In an embodiment, in order to facilitate the connection of the insulating member 16 and the third shielding member 17 and ensure the structural reliability of the connection of the insulating member 16 and the third shielding member 17, the insulating member 16 and the third shielding member 17 can be integrally injection molded.

[0077] In an embodiment, FIG. 16 is a structural schematic diagram of the insulating member 16 provided by the embodiment of the application from another perspective. Referring to FIG. 16, the insulating member 16 is provided with a through hole 161 at a position between the first cavity 11 and the second cavity 12, the first cavity 11 and the second cavity 12 are communicated through the through hole 161, and the signal pin 21 is inserted into the second cavity 12 through the through hole 161. The through hole 161 can be directly formed during the manufacturing process of the insulating member 16, and a plurality of through holes 161 can be provided, each signal pin 21 can be matched with a corresponding through hole 161, that is, the signal pin 21 can be electrically connected to the signal terminal 13 in the second cavity 12 after passing through the through hole 161.

[0078] In an embodiment, FIG. 17 is a structural schematic diagram of the signal terminal 13 provided by the embodiment of the application. Referring to FIG. 17, the signal terminal 13 includes a first elastic sheet 131 and a second elastic sheet 132, the first elastic sheet 131 and the second elastic sheet 132 are arranged along the thickness direction Z of the first needle seat 1, the first elastic sheet 131 includes a first clamping portion 131a, the second elastic sheet 132 includes a second clamping portion 132a, and a gap is maintained between the first clamping portion 131a and the second clamping portion 132a. The first elastic sheet 131 and the second elastic sheet 132 can each be a sheet-shaped structure made of metal material, the signal pin 21 can be inserted between the first elastic sheet 131 and the second elastic sheet 132 and can reliably abut against the first elastic sheet 131 and the second elastic sheet 132, thereby facilitating the connection of the signal pin 21 and the signal terminal 13.

[0079] In an embodiment, the distance between at least part of the first clamping portion 131a and the second clamping portion 132a is less than the thickness of the signal pin 21 in the thickness direction Z of the first needle seat 1. Exemplarily, the signal pin 21 can be a cylinder, and the thickness of the signal pin 21 in the thickness direction Z of the first needle seat 1 can be the diameter of the signal pin 21. Since the distance between at least part of the first clamping portion 131a and the second clamping portion 132a is less than the diameter of the signal pin 21, when the signal pin 21 is inserted between the first clamping portion 131a and the second clamping portion 132a, the signal pin 21 can push the first clamping portion 131a and the second clamping portion 132a away from each other, and the first clamping portion 131a and the second clamping portion 132a can elastically deform, and the elastic force generated by the elastic deformation can ensure that the first clamping portion 131a and the second clamping portion 132a can reliably abut against the signal pin 21, thereby ensuring effective electrical connection.

[0080] In an embodiment, at least part of the first clamping portion 131a on the first elastic sheet 131 and at least part of the second clamping portion 132a on the second elastic sheet 132 are electrically connected (the part M shown by the dashed line frame in FIG. 17). The signal on the signal pin 21 can be transmitted to the first clamping portion 131a of the first elastic sheet 131 and the second clamping portion 132a of the second elastic sheet 132, forming two signal paths, and at the position where the first elastic sheet 131 and the second elastic sheet 132 are electrically connected, the two signal paths can be combined into one signal path, so that the two signal paths can be transmitted along the same path, thereby ensuring that there is no transmission time difference between the two signal paths, and thus the signal transmission quality can be ensured.

[0081] In an embodiment, the first elastic sheet 131 and the second elastic sheet 132 are symmetrically arranged in the thickness direction Z of the first needle seat 1. That is, the first elastic sheet 131 and the second elastic sheet 132 can have the same structure, and by symmetrically arranging the first elastic sheet 131 and the second elastic sheet 132, the signal on the first elastic sheet 131 and the signal on the second elastic sheet 132 can have the same transmission path, thereby ensuring that there is no transmission time difference between the signals on the first elastic sheet 131 and the second elastic sheet 132, and thus the signal transmission quality can be ensured.

[0082] In an embodiment, the first clamping portion 131a and the second clamping portion 132a can be connected to the insulating member 16. Exemplarily, the first clamping portion 131a and the second clamping portion 132a can be connected to the insulating member 16 by welding, soldering, injection molding, screw connection, etc. Of course, the end positions of the first clamping portion 131a and the second clamping portion 132a can also be lapped on the insulating member 16, and the present embodiment does not limit this.

[0083] In an embodiment, Fig. 18 is a schematic view of the arrangement of the plurality of signal terminals 13 in the female connector 10 according to an embodiment of the present application. Referring to Fig. 18, two signal terminals 13 can be arranged in a transmission port 1A, and the two signal terminals 13 are arranged in the first direction X to form a differential pair, which can transmit opposite signals to reduce interference and provide high sensitivity and low noise. If the first spring piece 131 and the second spring piece 132 of each signal terminal 13 are arranged in the first direction X, the arrangement space of the signal terminal 13 in the first direction X will be increased, which will affect the arrangement of the adjacent signal terminal 13 in the transmission port 1A and the signal transmission performance. This requires a larger space in the first direction X in the transmission port 1A, and when a plurality of transmission ports 1A are arranged in the first direction X, the overall size of the female connector 10 in the first direction X will be increased, which is not conducive to the high-density design of the transmission port 1A.

[0084] Therefore, in the embodiment, the first spring piece 131 and the second spring piece 132 are arranged in the thickness direction Z of the first needle seat 1 instead of the first direction X, so that the transmission port 1A can be narrowed in the first direction X, which is conducive to improving the arrangement density of the plurality of transmission ports 1A and realizing the miniaturization design and high bandwidth of the female connector 10.

The fourth shielding member 24 and the fifth shielding member 25 can be plate-shaped structures made of metal conductive materials, such as aluminum and copper. The fourth shielding member 24 and the fifth shielding member 25 made of metal conductive materials have the function of shielding electromagnetic energy, which can attract the scattered electromagnetic energy of the signal pin 21 to avoid interference with other signal pins 21 and signal terminals 13.

[0086] In an embodiment, at least part of the fourth shield 24 and at least part of the fifth shield 25 constitute the grounding portion 22. That is, both the fourth shield 24 and the fifth shield 25 have grounding parts, and exemplary, both the fourth shield 24 and the fifth shield 25 can be provided with protruding structures which can serve as the aforementioned grounding portion 22. When the female connector 10 and the male connector 20 are plugged together, the protruding structures can be in contact with the conductive inner wall of the first cavity 11, for example, the protruding structure on the fourth shield 24 can be in abutment with the first shield 14, and the protruding structure on the fifth shield 25 can be in abutment with the second shield 15, so that the grounding can be achieved, and the transmission quality of the signals can be ensured.

Among them, the cross section of the second protruding portion 241 with the first flange 241a is in the shape of "U", which can form a semi-enclosed form on the first protruding portion 231, so that the second protruding portion 241 can have the effect of electromagnetic shielding on the signal pin 21 in multiple directions, preventing crosstalk.
