When the male head 10 is matched with the female head 20, the unmanned aerial vehicle is electrically connected with the battery, and at the moment, the battery can transmit a power supply signal to the unmanned aerial vehicle through the connector 300, so that power is supplied to the unmanned aerial vehicle; meanwhile, the battery may report the state information of the battery to the unmanned aerial vehicle through the connector 300, and the state information of the battery may include information such as voltage, current, and electric quantity of the battery.

Referring to fig. 3A to 4B, the male connector 10 may include a first housing 11 and an electrical plug 12, the electrical plug 12 is disposed on the first housing 11, and the electrical plug 12 is exposed from the first housing 11. The female plug 20 may include a second housing 21 and an electrical outlet 22, the electrical outlet 22 being provided in the second housing 21, and the electrical outlet 22 exposing the second housing 21. In the embodiment of the present invention, the electrical plug 12 is adapted to the electrical socket 22, so as to pair the male plug 10 and the female plug 20.

Hereinafter, the structures of the male and

female heads

10 and 20, respectively, will be explained in detail.

Referring to fig. 3B and 4A, the electrical plug 12 may include a positive terminal 121, a negative terminal 122, and a signal terminal group 123, wherein the positive terminal 121, the negative terminal 122, and the signal terminal group 123 are disposed side by side along a first direction and spaced apart from each other on a same side of the first housing 11, and the signal terminal group 123 is disposed between the positive terminal 121 and the negative terminal 122. The width directions of the positive electrode terminal 121 and the negative electrode terminal 122 are both parallel to the second direction, and the first direction is substantially perpendicular to the second direction. In the embodiment of the present invention, the signal terminal group 123 may include at least two signal terminals 1230, the at least two signal terminals 1230 are arranged side by side and at intervals along the second direction, and the width direction of the signal terminals 1230 is parallel to the second direction. In the embodiment of the present invention, the width of the signal terminal 1230 is smaller than the width of the positive terminal 121 and smaller than the width of the negative terminal 122. Further, each signal terminal 1230 is capable of transmitting signals, and it should be noted that the signal terminal 1230 is used for transmitting communication signals. Since the positive terminal 121 and the negative terminal 122 are used for transmitting power signals, the signal terminal 1230 is used for transmitting communication signals, and the current of the power signals is large and the current of the communication signals is small, the current flowing through the signal terminal 1230 does not need to be large generally, and the current flowing through the positive terminal 121 and the negative terminal 122 is large, so that the area of the signal terminal 1230 can be designed to be small, and thus, when the male head 10 is designed, designers can arrange the signal terminal 1230 on the basis of not increasing the volume of the male head 10 as much as possible, and simultaneously, the requirement of signal transmission of as many paths as possible can be met, and the miniaturization design of the connector 300 is facilitated.

The material of the first housing 11 may be plastic or other materials. In the embodiment of the present invention, the first housing 11 is a plastic part, and plays a role in supporting and protecting the positive electrode terminal 121, the negative electrode terminal 122 and the signal terminal 1230.

The number of the positive terminals 121 and the negative terminals 122 may be designed as required, and optionally, the number of the positive terminals 121 and the number of the negative terminals 122 are both multiple, and the number of the positive terminals 121 is equal to the number of the negative terminals 122, so as to increase the current capacity of the connector 300. Illustratively, the number of the positive terminals 121 and the negative terminals 122 is 4; of course, the number of positive terminals 121 and negative terminals 122 may be other depending on the current flow requirements of the connector 300.

The embodiment of the utility model provides an in, the quantity of positive terminal 121 and negative terminal 122 is a plurality ofly, and a plurality of positive terminals 121 are one row of interval and locate one side of signal terminal group 123, and a plurality of negative terminal 122 are one row of interval and locate the opposite side of signal terminal group 123. Illustratively, the positive terminals 121 and the negative terminals 122 are symmetrically arranged on two sides of the signal terminal group 123; of course, the positive terminals 121 and the negative terminals 122 may be asymmetrically disposed on both sides of the signal terminal group 123.

The width of the positive terminal 121 and the width of the negative terminal 122 may be equal or different. The thickness of the positive electrode terminal 121 and the thickness of the negative electrode terminal 122 may be equal or different. The height of the positive terminal 121 and the height of the negative terminal 122 may be equal or different. It should be noted that the thickness direction of the embodiment of the present invention is parallel to the first direction, and the height direction is perpendicular to the first direction and the second direction.

The following examples will be described by taking as an example that the positive electrode terminal 121 and the negative electrode terminal 122 are equal in size. It should be noted that, in the embodiment of the present invention, the size of the positive terminal 121 and the size of the negative terminal 122 are equal to each other, which means: the positive electrode terminal 121 and the negative electrode terminal 122 have the same width, the positive electrode terminal 121 and the negative electrode terminal 122 have the same thickness, and the positive electrode terminal 121 and the negative electrode terminal 122 have the same height.

In the embodiment of the present invention, the positive terminal 121 and the negative terminal 122 have the same structure.

The size of the signal terminals 1230 can be determined by factors such as the minimum current allowed by the signal terminals 1230, for example, the width of the signal terminals 1230 is less than or equal to half of the width of the positive terminal 121, and by designing such that the signal terminals 1230 can be arranged as many as possible in the second direction, so that the signal terminal group 123 has a greater number of signal terminals 1230, and the number of the signal terminals 1230 can be increased as much as possible on the basis of not increasing the volume of the male connector 10 in the second direction as much as possible, thereby increasing the number of signal transmission paths of the connector 300. For example, in one embodiment, the width of the signal terminal 1230 is half the width of the positive terminal 121.

Illustratively, in some embodiments, the thickness of the signal terminal 1230 is less than the thickness of the positive terminal 121 and less than the thickness of the negative terminal 122. Compared with the existing male head 10, under the same number of signal terminals 1230, the design manner of the thickness of the signal terminals 1230 according to the embodiment of the present invention can reduce the volume of the male head 10 in the first direction; alternatively, the number of the signal terminals 1230 is increased in the first direction of the male header 10 without increasing the volume of the male header 10 in the first direction as much as possible. Note that, the thickness of the embodiment of the present invention refers to the thickness in the first direction.

In other embodiments, the thickness of the signal terminal 1230 is equal to both the thickness of the positive terminal 121 and the thickness of the negative terminal 122.

The structures of the positive terminal 121, the negative terminal 122 and the signal terminal 1230 can be designed as required, for example, in some embodiments, the positive terminal 121 includes two first conductive sheets attached to each other, the negative terminal 122 includes two second conductive sheets attached to each other, and the signal terminal 1230 includes a third conductive sheet, and the thicknesses of the first conductive sheet, the second conductive sheet and the third conductive sheet are substantially equal.

In other embodiments, the positive terminal 121 includes two first conductive sheets attached to each other, the negative terminal 122 includes two second conductive sheets attached to each other, and the signal terminal 1230 includes two third conductive sheets, wherein the thicknesses of the first conductive sheet, the second conductive sheet, and the third conductive sheets are substantially equal.

It should be understood that the structures of the positive terminal 121, the negative terminal 122 and the signal terminal 1230 can be designed otherwise, such as the positive terminal 121 being a single conductive piece and/or the negative terminal 122 being a single conductive piece and/or the signal terminal 1230 being a single conductive piece.

The number of the signal terminal group 123 may be one or more. The number of the signal terminals 1230 in each signal terminal group 123 may be 2, 3, 4 or other numbers greater than 2, and for example, the number of the signal terminals 1230 in each signal terminal group 123 is 2.

Illustratively, the number of the signal terminal groups 123 is plural, such as 2, 3, 4 or others, and the plural signal terminal groups 123 are arranged side by side and spaced apart between the positive terminal 121 and the negative terminal 122. For example, in one possible embodiment, referring to fig. 4A, the number of the signal terminal sets 123 is 2, and includes a first signal terminal set 1231 and a second signal terminal set 1232.

The height of the signal terminals 1230 of the first signal terminal group 1231 and the height of the signal terminals 1230 of the second signal terminal group 1232 can be designed as desired, for example, in some embodiments, the height of the signal terminals 1230 of the first signal terminal group 1231 is less than the height of the positive terminal 121, and the height of the signal terminals 1230 of the first signal terminal group 1231 is less than the height of the signal terminals 1230 of the second signal terminal group 1232. When the electric plug 12 is in plug-in fit with the electric socket 22, if signal transmission exists between the signal terminals 1230 of the first signal terminal group 1231 and the signal sockets 2230 of the corresponding signal socket group 223, plug-in between the electric plug 12 and the electric socket 22 is successful. By designing the height of the signal terminals 1230 of the first signal terminal group 1231 to be shorter than the length of the other terminals, not only is the in-place detection function realized, i.e., whether the electrical plug 12 and the electrical outlet 22 are inserted in place is judged, but also when the electrical plug 12 and the electrical outlet 22 are inserted and matched, the terminals and the electrical outlet 22 can be inserted in place, so that the contact area after the terminals are inserted is ensured, and the risk that the connector 300 is burnt due to the fact that the contact area of the terminals is too small because the terminals are not inserted in place is reduced. Further, in some embodiments, the height of the signal terminal 1230 of the second signal terminal group 1232 is substantially equal to or greater than the height of the positive terminal 121, and when a metal foreign object or other conductive object falls on the connector 300, since the height of the signal terminal 1230 of the second signal terminal group 1232 is substantially equal to or greater than the height of the positive terminal 121, it is possible to avoid the occurrence of a short circuit between the positive and negative electrodes caused by one end of the metal foreign object or other conductive object contacting the positive terminal 121 and the other end contacting the negative terminal 122.

Referring again to fig. 4A, the electrical plug 12 may further include an insulating spacer 124 disposed on the first housing 11, and correspondingly, an insulating socket 224 disposed on the second housing 21 for mating with the insulating spacer 124.

The insulating isolation part 124 is disposed between the positive terminal 121 and the signal terminal group 123 and/or between the negative terminal 122 and the signal terminal group 123, and the insulating isolation part 124 is used for isolating a gap between the positive terminal 121 and at least two signal terminals 1230 of the signal terminal group 123 and/or isolating a gap between the negative terminal 122 and at least two signal terminals 1230 of the signal terminal group 123. If there is no shielding of the insulating spacer 124, when a foreign metal or other conductive object falls on the connector 300, the foreign metal or other conductive object may penetrate through a gap between the positive terminal 121 and at least two signal terminals 1230 of the signal terminal group 123 and a gap between the negative terminal 122 and at least two signal terminals 1230 of the signal terminal group 123, such that one end of the foreign metal or other conductive object contacts the positive terminal 121 and the other end contacts the negative terminal 122, thereby causing short circuit between the positive and negative electrodes. The embodiment of the utility model provides a through set up insulating isolation portion 124 between positive terminal 121 and signal terminal group 123 and/or between negative terminal 122 and signal terminal group 123, realized the isolation between positive terminal 121 and the negative terminal 122 to can avoid the emergence of positive negative pole short circuit problem.

Illustratively, an insulating partition 124 is provided between the positive terminal 121 and the signal terminal group 123 for separating a gap between at least two signal terminals 1230 of the positive terminal 121 and the signal terminal group 123; illustratively, an insulating partition 124 is provided between the negative terminal 122 and the signal terminal group 123 for separating a gap between the negative terminal 122 and at least two signal terminals 1230 of the signal terminal group 123; illustratively, an insulating partition 124 is provided between the positive terminal 121 and the signal terminal group 123 for separating a gap between at least two signal terminals 1230 of the positive terminal 121 and the signal terminal group 123; an insulating spacer 124 is provided between the negative terminal 122 and the signal terminal group 123 to separate a gap between the negative terminal 122 and at least two signal terminals 1230 of the signal terminal group 123.

When the positive terminal 121, the negative terminal 122, and the signal terminal group 123 include a plurality of positive terminals 121, a plurality of negative terminals 122, and a plurality of signal terminal groups 123, respectively, the insulating spacer 124 is provided between the positive terminal 121 and the signal terminal group 123, which are adjacent to each other, and the insulating spacer 124 is provided between the negative terminal 122 and the signal terminal group 123, which is adjacent to each other, and the insulating spacer 124 is provided between the negative terminal 122 and the signal terminal group 123.

The insulating spacer 124 may have a plate-like structure to reduce the weight of the insulating spacer 124; of course, the insulating spacer 124 may have other structures.

Illustratively, the insulating isolation portion 124 is a sheet-shaped structure, and the width direction of the insulating isolation portion 124 is substantially parallel to the second direction, and the insulating isolation portion 124 of this embodiment can completely separate the positive terminal 121 from the signal terminal group 123 and/or completely separate the negative terminal 122 from the signal terminal group 123, so as to better avoid the occurrence of the short circuit between the positive and negative electrodes.

To ensure that the insulating spacer 124 completely separates the positive terminal 121 from the set of signal terminals 123 and/or completely separates the negative terminal 122 from the set of signal terminals 123, the height of the insulating spacer 124 is illustratively substantially equal to or greater than the height of the positive terminal 121; illustratively, the width of the insulating spacer 124 is substantially equal to or greater than the width of the positive terminal 121; illustratively, the height of the insulating spacer 124 is substantially equal to or greater than the height of the positive terminal 121, and the width of the insulating spacer 124 is slightly greater than the width of the positive terminal 121. It should be understood that the thickness of the insulating spacer 124 may be designed in consideration of strength, size of occupied space, and the like.

When the insulating isolation portion 124 is disposed between the adjacent positive terminal 121 and the signal terminal group 123, the insulating isolation portion 124 (i.e., the insulating isolation portion 124 between the positive terminal 121 and the signal terminal group 123) is disposed at an interval with the positive terminal 121 and the signal terminal group 123, respectively, so that the insulating isolation portion 124 does not affect the signal transmission of the positive terminal 121 and the signal terminal 1230, and does not affect the structural design of the positive terminal 121 and the signal terminal 1230. The size of the space between the insulating isolation portion 124 and the positive terminal 121 and the size of the space between the insulating isolation portion 124 and the signal terminal group 123 can be designed as required, for example, the space between the insulating isolation portion 124 and the positive terminal 121 is approximately equal to the space between the insulating isolation portion 124 and the signal terminal group 123; further, the interval between the insulating spacer 124 and the positive electrode terminal 121 is slightly smaller than the interval between the positive electrode terminals 121 located adjacent to each other.

When the insulating isolation portion 124 is disposed between the negative terminal 122 and the signal terminal group 123, the insulating isolation portion 124 (i.e., the insulating isolation portion 124 between the negative terminal 122 and the signal terminal group 123) is disposed at an interval with the negative terminal 122 and the signal terminal group 123, respectively, so that the insulating isolation portion 124 does not affect the signal transmission of the negative terminal 122 and the signal terminal 1230, and the structural design of the negative terminal 122 and the signal terminal 1230 is not affected. The size of the space between the insulating isolation portion 124 and the negative terminal 122 and the size of the space between the insulating isolation portion 124 and the signal terminal group 123 can be designed as required, for example, the space between the insulating isolation portion 124 and the negative terminal 122 is approximately equal to the space between the insulating isolation portion 124 and the signal terminal group 123; further, the interval between the insulating spacer 124 and the negative electrode terminal 122 is slightly smaller than the interval between the adjacent negative electrode terminals 122.

The insulating isolation portion 124 may be made of plastic or other insulating materials. Illustratively, the insulating spacer 124 is a plastic sheet, which is light in weight.

It should be understood that the electrical plug 12 may be provided without the insulating barrier 124, such as the electrical plug 12 shown in fig. 3B; accordingly, electrical outlet 22 is also not provided with an isolation outlet 224, such as electrical outlet 22 shown in FIG. 3C.

Next, the structure of the male tab 10 will be further described by taking as an example that the number of the signal terminal groups 123, the number of the positive terminals 121, and the number of the negative terminals 122 are all plural, and the number of the positive terminals 121 is equal to the number of the negative terminals 122.

In the present embodiment, the plurality of signal terminal groups 123 are arranged side by side and spaced apart from each other between the positive terminal 121 and the negative terminal 122, the plurality of positive terminals 121 are spaced apart from each other in a row on one side of the plurality of signal terminal groups 123, and the plurality of negative terminals 122 are spaced apart from each other in a row on the other side of the plurality of signal terminal groups 123. Further, the positive terminals 121 and the negative terminals 122 are symmetrically disposed on both sides of the signal terminal groups 123, that is, the interval between the adjacent positive terminals 121 is equal to the interval between the adjacent negative terminals 122. Furthermore, the distance between the adjacent signal terminal groups 123 is greater than the distance between the adjacent positive terminals 121, and the distance between the adjacent signal terminal groups 123 is designed to be larger, so that the risk of short circuit caused by too small distance between the signal terminal groups 123 can be avoided.

Referring to fig. 3B and 4A again, the male header 10 may further include first water chutes 125 disposed between adjacent positive terminals 121 and/or between adjacent negative terminals 122 at intervals, for example, the first water chutes 125 are disposed between adjacent positive terminals 121, and the first water chutes 125 are spaced from the positive terminals 121 on both sides of the first water chutes 125; for example, a first water chute 125 is arranged between adjacent negative terminals 122, and the first water chute 125 is spaced from the negative terminals 122 on both sides of the first water chute 125; for example, first water chutes 125 are respectively disposed between adjacent positive terminals 121 and between adjacent negative terminals 122, the first water chutes 125 between adjacent positive terminals 121 and the positive terminals 121 on both sides of the first water chutes 125 have a gap, and the first water chutes 125 between adjacent negative terminals 122 and the negative terminals 122 on both sides of the first water chutes 125 have a gap.

In the embodiment of the present invention, the slotting direction of the first water guiding groove 125 is substantially parallel to the second direction, the first water guiding groove 125 may include at least one first water guiding opening, and the first water guiding opening is located at the edge of the first housing 11. When the electric plug 12 is in plug fit with the electric socket 22, the second housing 21 covers the first water chute 125, that is, when the electric plug 12 is in plug fit with the electric socket 22, the second housing 21 does not block the first water chute 125, and the first water chute 125 can lead out accumulated water between the adjacent positive terminals 121 and/or between the adjacent negative terminals 122 through the first water chute, so as to prevent the short circuit of the connector 300. The present embodiment makes the connector 300 suitable for complex environments, such as humid and watery environments, by providing the first water chute 125; in addition, the first water chute 125 can also reduce the weight of the male 10.

For example, the first water guiding groove 125 may include two first water guiding openings, the two first water guiding openings are respectively located at the edges of the first housing 11 on the corresponding sides, the depth of the first water guiding groove 125 gradually increases from a first position of the first water guiding groove 125 to the direction of the first water guiding opening, and the first position is located between the two first water guiding openings. In this embodiment, the depth of the two first water guiding openings and the first water guiding groove 125 may be designed to increase the speed of guiding out the accumulated water between the adjacent positive terminals 121 and/or between the adjacent negative terminals 122.

Referring to fig. 3B and 4A again, the male header 10 may further include a second water guiding trough 126 disposed between the adjacent signal terminal groups 123 at intervals, and the second water guiding trough 126 is spaced apart from the signal terminal groups 123 on both sides of the second water guiding trough 126. The grooving direction of the second water guiding groove 126 is substantially parallel to the second direction, and the second water guiding groove 126 includes at least one second water guiding opening, and the second water guiding opening is located at the edge of the second housing 21. When the electric plug 12 is in plug fit with the electric socket 22, the second water chute 126 is covered by the second housing 21, that is, when the electric plug 12 is in plug fit with the electric socket 22, the second water chute 126 is not blocked by the second housing 21, and the second water chute 126 can lead out accumulated water between adjacent signal terminal groups 123 through the second water chute, so that the short circuit of the connector 300 can be prevented. The embodiment makes the connector 300 suitable for complex environments, such as humid and watery environments, by providing the second water chute 126; in addition, the second water chute 126 can also reduce the weight of the male 10.

Illustratively, the second water guiding groove 126 includes two second water guiding openings, which are respectively located at the edges of the first housing 11 on the corresponding sides; the depth of the second water chute 126 gradually increases from a second position of the second water chute 126 to the second water guiding opening, and the second position is located between the two second water guiding openings. In this embodiment, the depth design of the two second water guiding ports and the second water guiding groove 126 increases the speed of guiding out the accumulated water between the adjacent signal terminal groups 123.

Illustratively, the male terminal 10 includes first water chutes 125 disposed at intervals between adjacent positive terminals 121 and/or adjacent negative terminals 122, and second water chutes 126 disposed at intervals between adjacent signal terminal groups 123, and optionally, the length of the second water chute 126 in the first direction is greater than the length of the first water chute 125 in the first direction. This is because the distance between the adjacent signal terminal groups 123 is greater than the distance between the adjacent positive terminals 121, and therefore the length of the second water guide groove 126 in the first direction can be designed to be greater than the length of the first water guide groove 125 in the first direction, which can increase the speed of draining accumulated water between the adjacent signal terminal groups 123, and can further reduce the weight of the male tab 10.

Referring to fig. 3B again, when the electrical plug 12 is not provided with the insulating isolation portion 124, the male plug 10 may further include a third water guiding channel disposed between the signal terminal group 123 (when the number of the signal terminal group 123 is multiple, the signal terminal group 123 is the signal terminal group 123 adjacent to the positive terminal 121) and the positive terminal 121 and/or between the signal terminal group 123 (when the number of the signal terminal group 123 is multiple, the signal terminal group 123 is the signal terminal group 123 adjacent to the negative terminal 122) and the negative terminal 122, for example, the third water guiding channel is disposed between the signal terminal group 123 and the positive terminal 121 and between the signal terminal group 123 and the negative terminal 122, wherein there is a gap between the third water guiding channel disposed between the signal terminal group 123 and the positive terminal 121 and between the signal terminal group 123 and the positive terminal 121, and a gap between the signal terminal group 123 and the positive terminal 121, and a third water guiding channel disposed between the signal terminal group 123 and the negative terminal 122 and the signal terminal group 123, The negative terminals 122 are spaced apart from each other.

The structure of the third water chute is the same as that of the first water chute 125, and thus, the description thereof is omitted.

Further, the number of the signal terminal groups 123 is plural, and the plural signal terminal groups 123 are symmetrically arranged, for convenience of description, a gap between adjacent signal terminals 1230 in the same signal terminal group 123 is referred to as a first gap, and the first gaps of different signal terminal groups 123 are aligned along the first direction. Referring to fig. 3B, the third water chutes on two sides of the signal terminals 1230 are communicated through the fourth water chute, and the fourth water chute passes through the aligned first slits. When the electric plug 12 is in plug-in fit with the electric socket 22, the second housing 21 covers the third water chute and the fourth water chute, that is, when the electric plug 12 is in plug-in fit with the electric socket 22, the second housing 21 does not block the third water chute and the fourth water chute, and the third water chute and the fourth water chute are in fit, so that accumulated water between the adjacent signal terminal group 123 and the positive terminal 121 and/or between the signal terminal group 123 and the negative terminal 122 and accumulated water between the adjacent signal terminals 1230 can be led out, thereby preventing the short circuit of the connector 300. In the embodiment, the third water chute and the fourth water chute are arranged, so that the connector 300 is suitable for complex environments, such as humid and watery environments; in addition, the third and fourth chutes also reduce the weight of the male 10. It is understood that the extending direction of the fourth water chute is parallel to the second direction.

In addition, in some embodiments, referring to fig. 3B to fig. 4B, the fixing portions 127 are respectively disposed on two sides of the first housing 11, and correspondingly, the fixing holes 225 for matching with the fixing portions 127 are disposed at corresponding positions of the second housing 21, so that the connection between the electrical plug 12 and the electrical socket 22 is faster and more secure by guiding and positioning the fixing portions 127 and the fixing holes 225.

The positive electrode terminal 121, the negative electrode terminal 122, and the signal terminal group 123 are disposed between the two fixing portions 127, the positive electrode terminal 121 is disposed at an interval from the fixing portion 127 on the corresponding side, and the negative electrode terminal 122 is disposed at an interval from the fixing portion 127 on the corresponding side.

The fixing portion 127 and the fixing hole 225 may be engaged, clipped, or otherwise engaged.

The fixing portion 127 may be designed as required, for example, referring to fig. 4A again, the fixing portion 127 may include a first fixing body 1271 and a second fixing body 1272, the first fixing body 1271 is disposed near the terminal on the corresponding side, and the second fixing body 1272 is attached to the side of the first fixing body 1271 away from the terminal. The dimension of the first fixing body 1271 along the second direction is greater than the dimension of the second fixing body 1272 along the second direction, and the height of the first fixing body 1271 is less than the height of the second fixing body 1272, so that the speed of inserting the fixing part 127 into the fixing hole 225 can be increased, and the male connector 10 and the female connector 20 can be conveniently plugged together by a user.

Optionally, the outer surface of the second fixing body 1272 is an arc surface, so that the speed of inserting the fixing portion 127 into the fixing hole 225 is further increased, and the arc surface is not easily worn in the inserting process, thereby prolonging the service life of the fixing portion 127. Wherein the outer surface is a surface of the second fixing body 1272 except for a surface attached to the second fixing body 1272.

Further optionally, the top of the second fixing body 1272 is provided with a leading end 12721, and the junction of the leading end 12721 and the first fixing body 1271 forms a step. The surface of the leading end 12721 facing the terminal is flat, and the dimension of the leading end 12721 gradually increases from the direction away from the first housing 11 to the direction closer to the first housing 11. By providing the leading end 12721 on the top of the second fixing body 1272, the speed of insertion of the fixing portion 127 into the fixing hole 225 is further increased.

In an embodiment of the present invention, the first fixing body 1271 and the second fixing body 1272 are integrally formed, so as to improve the structural strength of the fixing portion 127. Of course, in other embodiments, the first and

second fixing bodies

1271 and 1272 may be separate structures.

It should be understood that the fixing portion 127 may be designed in other configurations.

In addition, referring to fig. 3A, a plurality of first pins 128 are disposed on a side of the first housing 11 away from the positive terminal 121, and each of the positive terminal 121, the negative terminal 122 and the signal terminal group 123 is electrically connected to the plurality of first pins 128. In the embodiment of the present invention, one end of the first pin 128 departing from the first housing 11 is used for electrically connecting with the first device 100, so as to realize the electrical connection between the male terminal 10 and the first device 100.

The number of the first pins 128 electrically connected with the positive terminal 121 is equal to the number of the first pins 128 electrically connected with the negative terminal 122, and the number of the first pins 128 electrically connected with the signal terminal 1230 is smaller than the number of the first pins 128 electrically connected with the positive terminal 121. This is because the positive terminal 121 and the negative terminal 122 are both used for transmitting a power signal, the signal terminal 1230 is used for transmitting a communication signal, and the current of the power signal is greater than that of the communication signal, so the number of the first pins 128 electrically connected to the positive terminal 121 is equal to the number of the first pins 128 electrically connected to the negative terminal 122, and the number of the first pins 128 electrically connected to the signal terminal 1230 is less than the number of the first pins 128 electrically connected to the positive terminal 121.

Illustratively, the plurality of first pins 128 electrically connected to the same terminal are arranged side by side along the second direction. Of course, in other embodiments, the plurality of first pins 128 electrically connected to the same terminal may not be arranged side by side.

In addition, the electrical plug 12 of the embodiment of the present invention may be a symmetric structure, and may also be an asymmetric structure, and specifically may be designed as required.

Referring to fig. 3C and 4B, the electrical socket 22 includes a positive socket 221, a negative socket 222, and a signal socket set 223, wherein the positive socket 221 is mated with the positive terminal 121, the negative socket 222 is mated with the negative terminal 122, and the signal socket set 223 is mated with the signal terminal set 123, so as to realize the mating between the electrical plug 12 and the electrical socket 22.

In the embodiment of the present invention, the positive electrode socket 221, the socket negative electrode socket 222 and the socket signal socket group 223 are disposed on the same side of the socket second housing 21 side by side and at intervals along the first direction, and the socket signal socket group 223 is disposed between the socket positive electrode socket 221 and the socket negative electrode socket 222. The width directions of the socket positive socket 221 and the socket negative socket 222 are both parallel to the second direction, and the socket first direction is substantially perpendicular to the socket second direction. Socket signal socket group 223 includes at least two signal sockets 2230, where at least two socket signal sockets 2230 are arranged side by side and at intervals along the socket second direction, and the width direction of socket signal sockets 2230 is parallel to the socket second direction. The utility model discloses socket signal socket 2230's width is less than the width of the anodal socket 221 of socket to be less than the width of socket negative pole socket 222. Further, each jack signal socket 2230 is capable of transmitting signals, and it should be noted that signal sockets 2230 are configured to transmit communication signals. Since the positive jack 221 and the negative jack 222 are used for transmitting power signals, the signal jack 2230 is used for transmitting communication signals, the current of the power signals is large, and the current of the communication signals is small, so the current flowing through the signal jack 2230 generally does not need to be large, and the current flowing through the positive jack 221 and the negative jack 222 is large, so the area of the signal jack 2230 can be designed to be small, and thus, when the female head 20 is designed, the signal jack 2230 can be conveniently arranged by designers on the basis of not increasing the volume of the female head 20 as much as possible, the requirement of signal transmission of as many ground paths as possible can be met, and the miniaturization design of the connector 300 is facilitated.

The material of the second housing 21 may be plastic or other materials. In the embodiment of the present invention, the second housing 21 is a plastic part.

The number of positive sockets 221 is the same as the number of positive terminals 121, and the number of negative sockets 222 is the same as the number of negative terminals 122. Illustratively, the number of positive sockets 221 and the number of negative sockets 222 are both plural, and the number of positive sockets 221 is equal to the number of negative sockets 222, so as to increase the current capacity of the connector 300. Illustratively, the number of the positive sockets 221 and the negative sockets 222 is 4; of course, the number of positive sockets 221 and negative sockets 222 may be other depending on the current flow requirements of connector 300.

The embodiment of the utility model provides an in, the quantity of anodal socket 221, negative pole socket 222 are a plurality of, and a plurality of anodal sockets 221 are one row of intervals and locate one side of signal socket group 223, and a plurality of negative pole sockets 222 are one row of intervals and locate the opposite side of signal socket group 223. Illustratively, a plurality of positive sockets 221 and a plurality of negative sockets 222 are symmetrically arranged on two sides of the signal socket group 223; of course, the positive jacks 221 and the negative jacks 222 may be asymmetrically disposed on both sides of the signal jack group 223.

The width of the positive socket 221 and the width of the negative socket 222 may be equal or different. The thickness of the positive electrode socket 221 and the thickness of the negative electrode socket 222 may be equal or unequal. The depth of the positive socket 221 and the depth of the negative socket 222 may be equal or different.

The following embodiment will be described by taking as an example that positive electrode inlet 221 and negative electrode inlet 222 are equal in size. It should be noted that, in the embodiment of the present invention, the size of the positive electrode socket 221 and the size of the negative electrode socket 222 are equal to each other: the positive socket 221 and the negative socket 222 have the same width, the positive socket 221 and the negative socket 222 have the same thickness, and the positive socket 221 and the negative socket 222 have the same depth.

In the embodiment of the present invention, the positive electrode socket 221 and the negative electrode socket 222 have the same structure.

The size of signal sockets 2230 may be determined by the minimum current allowed by signal sockets 2230, for example, the width of signal sockets 2230 is less than or equal to half of the width of positive socket 221, and thus signal sockets 2230 may be arranged as many as possible in the second direction, so that signal socket set 223 has a greater number of signal sockets 2230, which increases the number of signal sockets 2230 as much as possible without increasing the volume of female head 20 in the second direction as much as possible, thereby increasing the number of signal transmission paths of connector 300. For example, in one embodiment, signal jack 2230 has a width that is half the width of positive jack 221.

Illustratively, in some embodiments, the thickness of signal socket 2230 is less than the thickness of positive socket 221 and less than the thickness of negative socket 222. Compared with the existing female head 20, under the same number of signal sockets 2230, the design manner of the thickness of the signal sockets 2230 of the embodiment of the present invention can reduce the volume of the female head 20 in the first direction; alternatively, the number of signal ports 2230 may be increased in the first direction of the female portion 20 without increasing the volume of the female portion 20 in the first direction as much as possible.

In other embodiments, signal sockets 2230 are the same thickness as positive sockets 221 and negative sockets 222.

Optionally, the inner side walls of the positive jack 221, the negative jack 222, and the signal jack 2230 are respectively provided with a conductive plate, which is matched with the corresponding terminal.

In the embodiment of the present invention, the number of the signal sockets 223 is the same as the number of the signal terminals 123, and the number of the signal sockets 2230 in the signal sockets 223 is also the same as the number of the signal terminals 1230 in the signal terminals 123. Illustratively, the number of the signal socket sets 223 may be one or more. Where the number of signal jacks 2230 in each signal jack group 223 may be 2, 3, 4, or other number greater than 2, illustratively, the number of signal jacks 2230 in each signal jack group 223 is 2.
