Therefore, the number of conductive terminals 70 corresponds to the number of metal electrons 20 . Further, an opening 62 is provided on the inner wall surrounding the socket 60 .

Referring to FIG. 5 , the insulating body 10 includes a plug-in end 12 and an opposite end 13 extending from the plug-in end 12 . The socket 60 accommodates a plurality of conductive terminals 70 in the connector housing 200 . Further, on the basis of opening the accommodating groove 16, a plurality of grooves 14 communicating with the accommodating groove 16 are further provided at the bottom surface of the accommodating groove 16, and the number of grooves 14 is consistent with the number of metal terminals 20 .

Referring to FIG. 6 , a plurality of metal terminals 20 are arranged in a single row, wherein one end of each metal terminal 20 is embedded in an end of the insulating body 10 that is different from the insertion end 12 , that is, the opposite end 13 described above, and the metal terminal 20 The other end forms a free end 22 and is partially accommodated in the groove 14 .

Further, in one embodiment, the free end 22 includes a guiding slope 222 and a bottom surface 224 connected with the guiding slope 222 , where the connection between the guiding slope 222 and the bottom surface 224 forms a sharp angle 226 , and the apex of the sharp angle 226 is located in the groove 14 . With this structure, the sharp corner 226 at the connection position between the guiding slope 222 and the bottom surface 224 can form a line, so as to be easily buried in the groove 14, so that it can ensure that the male connector 100 is plugged and connected to the female seat 200 at the last At the beginning of contact, the conductive terminal 70 first touches the guiding slope 222 of the metal terminal 20 .

The shielding shell 30 covers the outer body 10 to protect the insulating body 10 and the metal terminal 20 , and at the same time plays a role in fixing the insulating body 10 , the metal terminal 20 and the hook 40 . A through hole 32 is defined on a side of the shielding shell 30 away from the groove 14 , and the through hole 32 communicates with the accommodating groove 16 .

Continuing to refer to FIG. 2 , FIG. 3 , FIG. 5 and FIG. 6 , a part of the hook 40 is located in the shielding case 30 , and the part located in the shielding case 30 is in contact with the opposite end 13 of the insulating body 10 and/or the inner wall of the shielding case 30 Fixed connection. Referring to FIG. 3 , in this embodiment, specifically, the hook 40 includes an elastic portion 42 , an extension portion 44 connected to the elastic portion 42 , and a hook portion 46 connected to the extension portion 44 . The hook portion 46 is used to hook a part of the opposite end 13 of the insulating body to be fixedly connected to the insulating body 10 , the extension portion 44 rests on the upper surface of the insulating body 10 , and the elastic portion 42 passes through the through hole on the shielding shell 30 32 is exposed outside the shielding shell 30, as shown in FIG. 2 . Since the through hole 32 communicates with the accommodating groove 16 , the elasticity can move up and down in a small range along the thickness direction of the shielding case 30 in the through hole 32 under the action of an external force.

Specifically, when the male connector 100 is inserted into the female connector 200 , the elastic portion 42 first sinks slightly into the through hole 32 toward the groove 14 under the pressure of the inner wall surrounding the socket 60 . When the elastic portion 42 reaches the position of the opening 62 in the connector housing, it tilts away from the groove 14 and enters into the opening 62 to fix the male connector 100 on the connector housing 200 . When it is necessary to disassemble the connector male head 100 and the connector female seat 200, the user pulls the connector male head 100 away from the connector female seat 200. The connector male head 100 exits the connector female seat 200 smoothly.

In other embodiments, the hook 40 may not include the hook portion 46 . For example, the extension part 44 is directly welded on the inner wall of the shielding case 30 .

Continuing to refer to FIG. 6 , the bonding portion 50 is connected to the opposite end 13 of the insulating body 10 away from the insertion end 12 , and is electrically connected to the side of the metal terminal 20 away from the free end. The data line is electrically connected to the bonding portion 50 , so as to be electrically connected to the metal terminal 20 .

For example, the elastic card body 48 is directly extended from the portion surrounding the through hole 32 a of the shielding shell 30 , and the elastic card body 48 is arranged opposite to the through hole 32 a to realize the above-mentioned equivalent function, which will not be repeated here.

Continuing to refer to FIG. 6 , specifically, in this embodiment, the bottom 142 of the groove 14 is stepped, including a first bottom 1422 and a second bottom 1424 . The first bottom portion 1422 is disposed opposite to the free end 22 , and the second bottom portion 1424 is connected to the first bottom portion 1422 and extends toward an end different from the free end 22 of the metal terminal 20 . And the thickness of the first bottom 1422 is less than the thickness of the second bottom 1424, the thickness of the first bottom 1422 is made as small as possible to ensure that the free end 22 has a large enough space to move, so as to avoid the lowest point of the free end 22 and the groove. The bottom 142 of 14 creates friction. At the same time, the thickness of the second bottom 1424 cannot be made too thin, because the strength of the bottom 142 cannot be guaranteed if it is too thin, and it is very easy to be damaged.

Specifically, the thickness of the first bottom 1422 is 0.13-0.17 mm, and the thickness of the second bottom 1424 is 0.14-0.23 mm. Further, the thickness of the first bottom 1422 is 0.13 mm, and the thickness of the second bottom 1424 is 0.18 mm. In other embodiments, the thickness of the first bottom portion 1422 may also be 0.17mm, or any value in the range of 0.13mm-0.17mm. The thickness of the second bottom 1424 is 0.14mm or 0.23mm, or any value in 0.14mm-0.17mm.

Referring to FIG. 8 , in another embodiment, the bottom 142 of the groove 14 further includes a third bottom 1426 , the first bottom 1422 is arranged opposite to the apex of the sharp corner 226 , and the third bottom 1426 is far away from the first bottom 1422 toward the side of the metal terminal 20 . The free ends 22 extend in different directions, and the third bottom 1426 is located between the first bottom 1422 and the second bottom 1424 . Further, in general, the thicknesses of the first bottom 1422, the third bottom 1426 and the second bottom 1424 increase sequentially, and the use of this three-level stepped design can ensure the strength of the bottom 142, so that the groove 14 has the activity The space is large enough to better avoid friction between the lowest point and the first bottom 1422 and/or the third bottom 1426 when the free end 22 is pressed down. In other embodiments, the thicknesses of the first bottom 1422 , the second bottom 1424 and the third bottom 1426 may also increase sequentially.

Specifically, the thickness of the first bottom 1422 is 0.13-0.17mm, the thickness of the second bottom 1424 is 0.19-0.23mm, and the thickness of the third bottom 1426 is 0.14-0.22mm.

In this embodiment, the thickness of the first bottom 1422 is 0.13 mm, the thickness of the second bottom 1424 is 0.23 mm, and the thickness of the third bottom 1426 is 0.18 mm. In other embodiments, the thicknesses of the first bottom portion 1422 , the second bottom portion 1424 and the third bottom portion 1426 may be the endpoints or any value in the middle of the above respective numerical ranges.

Further, the length of the first bottom 1422 toward the extending direction of the second bottom 1424 is 0.8-1.0 mm. The length is set so that the first bottom 1422 can at least correspond to the apex of the sharp corner 226 and the bottom surface 224, that is, corresponding to the lowest point of the free end 22, thereby avoiding friction between the lowest point of the free end 22 and the first bottom 142 to the greatest extent. In this way, the contact position between the metal terminal 20 and the conductive terminal 70 is prevented from being rubbed, and excellent electrical connectivity is ensured when the male connector 100 and the female connector 200 are plugged together. In this embodiment, the length of the first bottom 1422 toward the extending direction of the second bottom 1424 is 0.8 mm. Specifically, the length of the second bottom 1424 and/or the third bottom 1426 is not specifically limited here.

Further, in one embodiment, the material of the insulating body 10 is one of liquid crystal polymer or polyphthalamide resin. Since these two materials have the characteristics of high tensile strength, high flexural modulus, low coefficient of thermal expansion and good dimensional stability, the strength of the bottom 142 of the groove 14 can be well guaranteed.

The material of the insulating body 10 is one of liquid crystal polymer or polyphthalamide resin, so that the bottom 142 of the groove 14 can be made as thin as possible while ensuring the strength of the bottom 142 of the groove 14 . Specifically, the bottom 142 may not be stepped. Referring to FIG. 9 , in this embodiment, the upper surface of the bottom is flat, and the thickness of the bottom 142 is 0.13mm-0.17mm. Specifically, in one embodiment, the thickness of the bottom 142 is 0.13mm or 0.17mm. Adopting such a structure can increase the depth of the groove 14 to the greatest extent, and better avoid friction between the lowest point of the free end 22 and the bottom 142 of the groove 14 .

In the embodiment corresponding to FIG. 6 , the portion of the bottom surface 224 close to the guiding slope 222 is an arc surface. The arc surface slightly protrudes toward the groove 14 .

In order to better avoid friction between the free end 22 and the bottom 142 of the groove 14 when the free end 22 is pressed down toward the groove 14 , the bottom surface 224 can be set as a plane, as shown in FIG. 10 . Or set it as a concave curved surface away from the groove 14, as shown in FIG. 11 . In the above two cases, the portion of the bottom surface 224 closest to the bottom 142 of the groove 14 is the apex of the sharp corner 226 . Therefore, friction between the free end 22 and the bottom surface 142 of the groove 14 can be well avoided, thereby avoiding friction between the contact parts of the conductive terminal 70 and the metal terminal 20 , ensuring that the conductive terminal 70 and the metal terminal 20 have excellent electrical conductivity.

Continuing to refer to FIG. 1 , the present application also provides a connector assembly. The connector assembly 300 includes the male connector 100 and the female connector 200 described in the above embodiments, which will not be repeated here.

In order to better reflect the improvements of the present application, the process of inserting and withdrawing the male connector 100 and the female connector 200 of the present application will be described in detail below.

12 and 13, when the male connector 100 is just inserted into the socket 60 of the female connector 200, the conductive terminal 70 of the female connector 200 enters the accommodating groove 16 and just touches the metal terminal of the male connector 100. The guide slope 222 of 20 is close to the apex side of the sharp corner 226, as shown in FIG. 12 . As the connector male head 100 is further inserted into the connector female seat 200, the conductive terminal 70 moves along the guiding slope 222 away from the apex of the sharp corner 226, and at the same time, the free end 22 of the metal terminal 20 moves towards the groove under the action of the conductive terminal 70 14 until the male connector 100 is completely inserted into the female connector 200, as shown in FIG. 13 . Referring to FIG. 2 at the same time, in the above process, the elastic part 42 or the elastic card body 48 first sinks slightly into the through hole 32 toward the groove 14 under the pressure of the inner wall surrounding the socket 60 . When the elastic part 42 or the elastic card body 48 reaches the position of the opening 62 in the connector base 200, it slightly tilts away from the groove 14 and enters the opening 62 to fix the connector male head 100 on the connector base. 200 , the male connector 100 is fully inserted into the female connector 200 at this time, and the free end 22 is closest to the bottom of the groove 14 .

Because at least the first bottom 1422 of the bottom 142 in the present application is made thinner than the prior art, it is 0.13mm-0.17mm, the depth of the groove 14 can be made deeper, thereby avoiding the bottom surface 224 or sharp corner 226 of the free end 22. The apex rubs against the bottom 142 of the groove 14 , thereby avoiding friction between the metal terminal 20 and the conductive terminal 70 . In other embodiments, without improving the bottom 142 of the groove 14, or on the basis of improving the bottom 142 of the groove 14, the bottom surface 224 of the free end 22 may be set as a plane (as shown in FIG. 10 ) or A curved surface that is concave toward the direction away from the groove 14 (as shown in FIG. 11 ). The bottom surface 224 adopts such a structure. Compared with the metal terminal 20a in the prior art, the lowest point of the free terminal 22 of the present application is farther away from the bottom 142 of the groove 14 , further avoiding the possibility of friction with the bottom 142 of the groove 14 .

On the contrary, when the male connector 100 needs to be withdrawn from the female connector seat 200, first the male connector 100 is slightly withdrawn from the socket 60 under the external force, and at this time, the elastic part 42 or the elastic card body 48 is pulled by the external force. The exit opening 62 prepares for further exiting the male connector 100 from the female connector 200 . Then, as the connector male head 100 gradually withdraws from the socket 60, the free end 22 of the metal terminal 20 slowly tilts away from the groove 14, and at the same time, the guide slope 222 slowly moves from the side away from the groove 14 to the apex near the sharp corner 226. Slowly slide over the end of the conductive terminal 70 and out of the socket 60 .

Referring to FIG. 13 and FIG. 14 , the present application also provides a terminal system, which includes a terminal 80 and the male connector 100 described in the above embodiments. The terminal 80 is provided with a connector female seat 200, one end of the connector female seat 200 is provided with a socket 60, and a plurality of conductive terminals 70 are arranged in the socket 60, and the connector male head 100 is partially inserted into the socket 60, so that the metal terminal 20 The guiding slope 222 is first in contact with the conductive terminal 70 of the connector housing 200 . The details are consistent with those described in the above embodiments, and will not be repeated here.

Specifically, the terminal 80 in this application may be a mobile phone, an IPad, a smart wearable device, a digital audio and video player, an e-reader, a handheld game console, an on-board electronic device, a digital camera, a printer, a flash drive, and the like.

The above is only the implementation of the application, and does not limit the patent scope of the application. Any equivalent structure or equivalent process conversion made by using the specification and drawings of the application, or directly or indirectly used in other related technologies fields, are all included in the scope of patent protection of this application in the same way.
