[0029] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] See also Figure 1 and Figure 2 As shown, the present invention discloses a connector assembly 100 , comprising a socket 10 and a plug 20 connected to the socket 10 .

[0031] See also Figure 2 and Figure 3 As shown, the socket 10 includes a housing 11 and a conductive terminal 12 mounted within the housing 11. The housing 11 includes a base 111, a fixing base 112 extending from the base 111 toward the plug 20, and an end cap 113 that cooperates with the fixing base 112. The end cap 113 and the fixing base 112 are integrally injection-molded to form a flip-top structure, so that the end cap 113 can be folded downward to achieve a fixed connection with the fixing base 112. Of course, in other embodiments, the end cap 113 and the fixing base 112 can also be independent components, so that the end cap 113 can be directly snap-fitted to the fixing base 112.

[0032] The base 111 includes a base 1111 and a docking body 1112 extending from the base 1111 toward the plug 20. A receiving groove 1113 is formed within the docking body 1112 to accommodate the plug 20. The base 111 also includes a tongue plate 1114 protruding from the receiving groove 1113. A receiving cavity 1115 is provided within the tongue plate 1114. The tongue plate 1114 is preferably a plastic isolation ring.

[0033] The conductive terminal 12 includes a first conductive portion 121 and a second conductive portion 122. The first conductive portion 121 is received within the receiving cavity 1115, so that the tongue plate 1114 can isolate the first conductive portion 121 to prevent the user from electric shock. The first conductive portion 121 is used to connect with the plug 20 to transmit electricity. In this embodiment, the first conductive portion 121 is cylindrical. The second conductive portion 122 is retained within the base 1111 and is used to electrically connect to the power cord 30 to obtain electricity.

[0034] The fixing base 112 includes a bottom wall 1121 and side walls 1122 disposed on both sides of the bottom wall 1121. The bottom wall 1121 and the side walls 1122 are arranged to form a receiving cavity 1123 to receive the light strip 40 (such as Figure 8 and Figure 9 ). A first snap-fit ​​portion 11221 is provided on the outer surface of the side wall 1122. The end cap 113 is configured to cooperate with the fixing base 112 to secure the light strip 40 within the accommodating cavity 1123. The end cap 113 is provided with a second snap-fit ​​portion 1131 that cooperates with the first snap-fit ​​portion 11221, thereby securing the end cap 113 to the fixing base 112 through the mutual snap-fit ​​between the first snap-fit ​​portion 11221 and the second snap-fit ​​portion 1131.

[0035] In this embodiment, the first snap-fitting portion 11221 is a protrusion, and the second snap-fitting portion 1131 is a groove that cooperates with the protrusion. Of course, in other embodiments, the first snap-fitting portion 11221 may also be a groove, and the second snap-fitting portion 1131 may be a protrusion that cooperates with the groove; or the first snap-fitting portion 11221 and the second snap-fitting portion 1131 may also be other mutually cooperating structures, which are not limited here.

[0036] The inner wall surface of the end cap 113 is provided with a plurality of abutting portions 1132 for abutting and pressing the light strip 40 so that the light strip 40 is firmly fixed in the accommodating cavity 1123. Preferably, the ends of the abutting portions 1132 are sharpened so that when the abutting portions 1132 abut the light strip 40, the abutting portions 1132 can penetrate the light tubes of the light strip 40, thereby fixing and positioning the light strip 40 in the axial direction of the light strip 40.

[0037] Furthermore, a plurality of ribs 11222 are provided on the outer wall surface of the side wall 1122 to prevent the user from disassembling it with bare hands, thereby avoiding the risk of electric shock to the user.

[0038] See also Figures 4 to 7 As shown, the plug 20 is used to connect with the socket 10 and includes an insulating body 21 and a plug-in terminal 22. In this embodiment, the insulating body 21 and the plug-in terminal 22 are integrally injection-molded. The insulating body 21 includes a base 211, a plug-in portion 212 extending from the base 211 toward the socket 10, and an extension portion 213 extending from the base 211 away from the socket 10. The plug-in portion 212 is provided with an insertion cavity 2121 for accommodating the plug-in terminal 22 and the tongue plate 1114. When the plug 20 is plugged into the socket 10, the plug-in portion 212 is located between the inner sidewall of the mating body 1112 and the tongue plate 1114.

[0039] The plug-in terminal 22 includes a docking portion 221 that interfaces with the conductive terminal 12 and a contact portion 222 that electrically connects to the light strip 40. The docking portion 221 is hollow and needle-shaped, capable of being inserted into the first conductive portion 121 to electrically connect the docking portion 221 and the first conductive portion 121. The contact portion 222 includes a contact arm 2221 and an extension arm 2222 that extends from one end of the contact arm 2221. The extension portion 213 is at least partially covered by the contact arm 2221 and the extension arm 2222.

[0040] Simply put, the plug-in terminal 22 of the present invention is formed by bending sheet metal, so that the bending size can be adjusted according to the different cross-sections of the light strip 40, facilitating manufacturing. The docking portion 221 has a round pin structure, which is convenient for insertion into the receiving cavity 1115 to electrically contact the first conductive portion 121. The contact portion 222 has a square structure, and the contact arm 2221 and the extension arm 2222 tightly cover the extension portion 213, thereby effectively enhancing the rigidity of the contact portion 222, thereby preventing deformation of the plug-in terminal 22 and preventing phenomena such as incomplete contact and looseness. Preferably, two extension arms 2222 are provided, symmetrically arranged on both sides of the contact arm 2221.

[0041] Combine Figure 8 and Figure 9 As shown, the plug terminal 22 also includes a connecting portion 223 connecting the docking portion 221 and the contact arm 2221. The connecting portion 223 extends obliquely so that the plane of the contact arm 2221 is lower than the plane of the docking portion 221. This allows the height of the contact portion 222 to be adjusted according to the bottom thickness of the light strip 40. This allows the extending arm 2222 to support the light tube of the light strip 40, while the contact arm 2221 can closely fit the circuit board 41 of the light strip 40 for effective contact. Of course, if the light tube of the light strip 40 is thick enough, the connecting portion 223 can also be set to extend horizontally, which is not a limitation here.

[0042] Furthermore, both the extension arm 2222 and the extension portion 213 are chamfered to facilitate insertion of the extension arm 2222 and the extension portion 213 into the light tubes of the light strip 40. Specifically, a first, inclined guide surface 2131 is provided on the side of the extension portion 213 facing the light strip 40 to guide the plug 20 into the light strip 40. In the thickness direction of the insulating body 21, the extension arm 2222 extends to the same height as the extension portion 213. A second, inclined guide surface 2223 is also provided on the side of the extension arm 2222 facing the light strip 40, with the first and second guide surfaces 2131 and 2223 being coplanar. This configuration allows the plug 20 to be smoothly inserted into the light tubes of the light strip 40, utilizing the combined guidance of the first and second guide surfaces 2131 and 2223.

[0043] Furthermore, the extension arm 2222 and the extension portion 213 are configured to form an interference fit with the light tubes of the light strip 40, thereby allowing the contact arm 2221 to closely contact the circuit board 41 of the light strip 40, thereby effectively preventing poor contact. Preferably, the height of the extension arm 2222 and the extension portion 213 can be appropriately increased to achieve an interference fit between the plug 20 and the light strip 40, thereby improving electrical contact reliability and preventing the plug 20 from falling off during installation.

[0044] Furthermore, a stress-bearing groove 2111 is provided on the insulating body 21 . When the plug 20 is inserted into the receiving groove 1113 , the stress-bearing groove 2111 is exposed in the fixing seat 112 , so that when disassembling, the user can push out the plug 20 through the stress-bearing groove 2111 .

[0045] See also Figure 10As shown, in another embodiment of the plug 20, the insulating body 21 and the plug terminals 22 are integrally injection-molded. The base 211 further includes a frame 2112 extending away from the socket 10. Along the width of the insulating body 21, the extension arm 2222 abuts against the frame 2112 and is at least partially located between the frame 2112 and the extension 213. This arrangement further enhances the tight fit between the plug 20 and the light strip 40.

[0046] When using the connector assembly 100 of the present invention, first insert the plug 20 into the light strip 40 , then insert the plug 20 and the light strip 40 as a whole into the socket 10 , and finally, snap-connect the end cover 113 to the fixing base 112 .

[0047] In summary, compared with the prior art, the connector assembly 100 of the present invention utilizes the contact arm 2221 and the extension arm 2222 to cover the extension portion 213 to enhance the strength of the plug-in terminal 22, thereby preventing the plug-in terminal 22 from deforming, thereby avoiding incomplete contact, looseness, and the like.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
