[0031] 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.

[0032] See also Figure 1 and Figure 2As shown, the present invention discloses an electrical connector 100, comprising a housing 10 and a conductive terminal 20 mounted in the housing 10. The conductive terminal 20 comprises a docking portion 21 for docking with a light strip 30 and a connecting portion (not shown) electrically connected to a power cord.

[0033] Combine Figure 3 As shown, the shell 10 includes a base 11, a fixing base 12 extending outward from the base 11, and an end cover 13 that cooperates with the fixing base 12. The connecting portion is fixed in the base 11, and the docking portion 21 protrudes out of the base 11. The fixing base 12 includes a bottom 121 and side portions 122 located on both sides of the bottom 121. The bottom 121 and the side portions 122 together enclose a receiving cavity 123 for accommodating the light strip 30, and the docking portion 21 is located in the receiving cavity 123. The end cover 13 is arranged below the fixing base 12 and is movably connected to the fixing base 12, that is, the end cover 13 can move up and down relative to the fixing base 12. This arrangement allows the docking portion 21 of the conductive terminal 20 to be surrounded by the end cover 13 and the fixing base 12 to prevent the operator from accidentally touching the docking portion 21 and causing the risk of electric shock.

[0034] A first abutting portion 1211 is provided on the side of the bottom portion 121 facing the receiving cavity 123. The first abutting portion 1211 is used to abut the light strip 30. In this embodiment, the first abutting portion 1211 is arranged in an elongated strip shape and extends along the mating direction between the electrical connector 100 and the light strip 30. Preferably, a guide portion 1212 is further provided on the end of the first abutting portion 1211 facing away from the base 11 to guide the light strip 30 into the receiving cavity 123.

[0035] A first limiting buckle 1221 and a first fixing buckle 1222 are provided on a side of the side portion 122 facing away from the receiving cavity 123 . The end cap 13 is used to cooperate with the fixing base 12 to fix the light strip 30 in the receiving cavity 123 .

[0036] See also Figures 4 to 6 Combined with Figure 2As shown, the end cap 13 is correspondingly provided with a second limiting buckle 131 that cooperates with the first limiting buckle 1221 and a second fixing buckle 132 that cooperates with the first fixing buckle 1222. When the electrical connector 100 is used, the end cap 13 is first pressed onto the fixing base 12, so that the end cap 13 is in the first state. At this time, the first limiting buckle 1221 cooperates with the second limiting buckle 131, so that the end cap 13 is pre-fixed to the fixing base 12. At this time, the first fixing buckle 1222 and the second fixing buckle 132 are not yet clamped and fixed. The overall height of the fixing base 12 and the end cap 13 is H1, and the height of the receiving cavity 123 located between the fixing base 12 and the end cap 13 is greater than the diameter of the light strip 30.

[0037] Such a configuration makes it convenient for the user to insert the light strip 30 into the receiving cavity 123; at the same time, since the end cover 13 is in a pre-fixed state, that is, the end cover 13 is fixed on the fixing seat 12, and the distance between the two is large enough, it is not only convenient for the user to install and fix the electrical connector 100 and the light strip 30, but also the docking portion 21 of the conductive terminal 20 can be protected, effectively avoiding the risk of electric shock during on-site installation.

[0038] like Figure 7 and Figure 8 As shown, when the user inserts the light strip 30 into the receiving cavity 123, they continue to press the end cap 13, placing the end cap 13 in the second state. At this point, the first limiting buckle 1221 and the second limiting buckle 131 disengage, and the first fixing buckle 1222 and the second fixing buckle 132 engage with each other, securing the end cap 13 to the fixing base 12 and simultaneously pressing and securing the light strip 30 within the receiving cavity 123. At this point, the combined height of the fixing base 12 and the end cap 13 is H2. Here, height H1 is greater than height H2.

[0039] That is to say, the end cover 13 is first pre-fixed on the fixing base 12, and then the light strip 30 is inserted into the receiving cavity 123, and finally the end cover 13 is installed on the fixing base 12 by a movable installation method that moves up and down, so that the end cover 13 and the fixing base 12 are fastened. This not only avoids the risk of electric shock during on-site installation, but also places the end cover 13 under the fixing base 12, making the electrical connection between the light strip 30 and the conductive terminal 20 more reliable.

[0040] See also Figure 6As shown, preferably, when the end cover 13 is in the first state, the outer wall surface of the first fixing buckle 1222 abuts against the outer wall surface of the second fixing buckle 132. This configuration can prevent the end cover 13 from shaking up and down when in the first state. Of course, it is understandable that in other embodiments, when the end cover 13 is in the first state, the first fixing buckle 1222 and the second fixing buckle 132 can also be constructed with a gap therebetween, so that the end cover 13 can move along the docking direction of the first fixing buckle 1222 and the second fixing buckle 132.

[0041] Furthermore, two first fixing buckles 1222 are provided and symmetrically arranged on both sides of the first limiting buckle 1221; two second fixing buckles 132 are also provided and symmetrically arranged on both sides of the second limiting buckle 131. Preferably, a partition wall 1223 is provided between the first fixing buckle 1222 and the first limiting buckle 1221 to guide and limit the second fixing buckle 132 and the second limiting buckle 131.

[0042] In this embodiment, the first limiting buckle 1221 is a limiting step, and the second limiting buckle 131 is a limiting elastic arm that cooperates with the limiting step; the first fixing buckle 1222 is a fixing step, and the second fixing buckle 132 is a fixing elastic arm that cooperates with the fixing step. Of course, it is understandable that in other embodiments, the first limiting buckle 1221 can also be a limiting elastic arm, in which case the second limiting buckle 131 is a limiting step that cooperates with the limiting elastic arm; the first fixing buckle 1222 can also be a fixing elastic arm, in which case the second fixing buckle 132 is a fixing step that cooperates with the fixing elastic arm.

[0043] See also Figure 3 and Figure 4As shown, the first fixing buckle 1222 is provided with a first guide surface 12221, and the second fixing buckle 132 is provided with a second guide surface 1321 that cooperates with the first guide surface 12221. When the end cover 13 is in the first state, the first guide surface 12221 and the second guide surface 1321 are abutted against each other; the first limiting buckle 1221 is provided with a third guide surface 12211, and the second limiting buckle 131 is provided with a fourth guide surface 1311 that cooperates with the third guide surface 12211. The arrangement of the first guide surface 12221, the second guide surface 1321, the third guide surface 12211 and the fourth guide surface 1311 facilitates the snap fit between the first limit buckle 1221 and the second limit buckle 131, and also facilitates the snap fit between the first fixing buckle 1222 and the second fixing buckle 132, thereby making the assembly fit between the end cover 13 and the fixing seat 12 easier and more convenient.

[0044] See also Figure 4 As shown, a second abutting portion 133 is provided on the side of the end cap 13 facing the receiving cavity 123. The second abutting portion 133 is used to abut the light strip 30 to secure the light strip 30 within the receiving cavity 123. Preferably, the end of the second abutting portion 133 facing the light strip 30 is sharp. With this configuration, when the second abutting portion 133 abuts the light strip 30, it can penetrate into the light tube 31 of the light strip 30, thereby effectively securing the light strip 30 within the receiving cavity 123.

[0045] See also Figure 9 As shown, the light strip 30 includes a light board 32, light-emitting elements mounted on the light board 32, and a light tube 31 that houses the light board 32 and the light-emitting elements. The electrical connector 100 and the light strip 30 are configured such that, in the thickness direction of the electrical connector 100, the conductive terminals 20 and the end caps 13 are located on the upper and lower sides of the light board 32, respectively. The end caps 13 are preferably located on the side of the light board 32 facing away from the light-emitting elements. This arrangement allows for better compression of the solder pads of the light strip 30, effectively ensuring reliable electrical contact.

[0046] To sum up, the electrical connector 100 of the present invention first uses the cooperation of the first limit clip 1221 and the second limit clip 131 to pre-fix the end cover 13 on the fixed seat 12, and then uses the cooperation of the first fixing clip 1222 and the second fixing clip 132 to stably fix the end cover 13 on the fixed seat 12, thereby effectively avoiding the risk of electric shock during on-site installation.

[0047] 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.
