[0030] Example 1

[0031] See Figure 1 and Figure 2 The present application provides an electrical connector, which comprises a female connector 100 and a male connector 200. The female connector 100 comprises a female base 110, at least two plug-in bodies 111 arranged on the female base 110, and at least two female terminals 120. The plug-in bodies 111 are provided with accommodating grooves 1111, and the female terminals 120 can be arranged in the accommodating grooves 1111. The male connector 200 comprises a male base 210 and at least two male terminals 220. The male base 210 is provided with plug-in grooves 211 corresponding to the number of the plug-in bodies 111 arranged on the female base 110. The male terminals 220 are arranged in the plug-in grooves 211, and the length of the male terminals 220 in the plug-in grooves 211 is less than the extension length of the plug-in grooves 211, i.e. the top surface of the male terminals 220 is lower than the surface of the male base 210. The plug-in grooves 211 are used to accommodate the plug-in bodies 111, and the plug-in bodies 111 can be wholly or partially accommodated in the plug-in grooves 211, so that the female terminals 120 and the male terminals 220 are electrically connected.

[0032] The female seat base 110 and the male seat base 210 are both insulators that can bear elastic deformation, so the female seat base 110 and the male seat base 210 are in interference fit when the plug-in body 111 and the plug-in groove 211 are connected.

[0033] Further, the outer portion of the end of the plug-in body 111 away from the female seat base 110 is formed with a guide surface 1115, so that the outer diameter of the end of the plug-in body 111 away from the female seat base 110 gradually decreases along the insertion direction of the plug-in body 111, thereby providing guidance for the plug-in body 111 to be inserted into the plug-in groove 211, so that the plug-in body 111 is more easily inserted into the plug-in groove 211, improving user experience. It should be noted that in other embodiments, the guide surface 1115 can also be formed on the inner wall of the plug-in groove 211, so that the inner diameter of the plug-in groove gradually decreases along the insertion direction of the plug-in body 111, thereby providing guidance for the plug-in body 111 to be inserted into the plug-in groove 211.

[0034] In this embodiment, the female terminal 120 is a tubular conductor, i.e., the female terminal 120 is a hollow cylindrical conductor, and the male terminal 220 is a needle-shaped conductor, which is inserted into the female terminal 120 to electrically connect the female terminal 120 and the male terminal 220.

[0035] Further, the top of the free end of the female terminal 120 is formed with an inclined surface, so that the inner diameter of the free end of the female terminal 120 gradually increases along the insertion direction of the plug-in body 111, thereby providing guidance for the male terminal 220 to be inserted into the female terminal 120. It should be noted that in other embodiments, the inclined surface can also be provided on the top of the male terminal 220, so that the diameter of the male terminal 220 gradually increases along the insertion direction of the plug-in body 111, which can also provide guidance for the male terminal 220 to be inserted into the female terminal 120.

[0036] Further, the length of the female terminal 120 in the accommodation groove 1111 is less than the extension length of the accommodation groove 1111, i.e., the top surface of the female terminal 120 is lower than the surface of the plug-in body 111, so that the female terminal 120 is not easily touched when the female connector 100 and the male connector 200 are disconnected, further improving the safety performance of the electrical connector.

[0037] Further, the plug-in body 111 can also cover the top surface of the female terminal 120, i.e., the female terminal 120 cannot be seen in the top view, thereby further improving the safety performance of the electrical connector.

[0038] Optionally, the male base body 210 is provided with at least one second sealing ring 212 in the insertion slot 211, which can not only make the male base body 210 and the insertion body 111 sealingly abut, so that the electrical connector can adapt to a humid environment or underwater work, but also make the male base body 210 and the insertion body 111 more stable in insertion, thereby preventing the male base body 210 and the insertion body 111 from being separated from the insertion.

[0039] Optionally, the female base body 110 is provided with a foolproof column 112, and the male base body 210 is formed with a foolproof slot 213 matched with the foolproof column 112. In the case that the female connector 100 has a plurality of female terminals 120 and the male connector 200 has a plurality of male terminals 220, the cooperation of the foolproof column 112 and the foolproof slot 213 can make the female terminals 120 and the male terminals 220 accurately one-to-one corresponding, thereby further improving the user experience. In other embodiments, the foolproof design of the electrical connector can also be jointly constituted by at least one insertion body and at least one insertion slot, such as by changing the shape or size of the insertion body and the insertion slot.

In this way, the male base body 210 and the insertion body 111 can be sealingly abutted, so that the electrical connector can adapt to a humid environment or underwater work, and there is no need to additionally equip the female connector 100 and the male connector 200 with connecting pieces. Through the sealing design, the male base body 210 and the insertion body 111 can be more stable in insertion, thereby preventing the male base body 210 and the insertion body 111 from being separated from the insertion.

The male terminal 220 is provided with a waterproof piece 230, and the waterproof piece 230 sealingly abuts against the sealing protrusion 1112 to seal the female terminal 120 and the male terminal 220 when the female connector 100 and the male connector 200 are inserted, so that the electrical connector can adapt to a humid environment or underwater work. It should be noted that in other embodiments, the sealing protrusion 1112 can also be provided outside the waterproof piece 230.

[0044] Optionally, the waterproof member 230 comprises a gradual change section and a uniform section connected with the gradual change section, the gradual change section and the uniform section are arranged in sequence along the insertion direction of the plug-in body 111, and the outer diameter of the gradual change section gradually increases along the insertion direction of the plug-in body 111, and the outer diameter of the uniform section remains unchanged along the insertion direction of the plug-in body 111, so that the plug-in body 111 is more easily inserted into the plug-in slot 211.
