[0002] The terminal structure is a common electrical connection device. The terminal structure is connected to the wire and is connected to the electrical equipment through plugging and unplugging to achieve quick disassembly and assembly.

[0003] The current terminal structure needs to be tinned on its outer surface when in use, and the tinning of the terminal can effectively prevent the copper terminal from being oxidized, improve the conductivity, and extend the service life for anti-oxidation;

[0004] However, the existing terminal structure will have part of the terminal pins exposed after installation. Due to the lack of a certain protective structure, the terminal pins exposed after installation are easily oxidized, resulting in poor contact. In addition to poor conductivity, it will also bring hidden dangers to future use.

[0005] In view of this, this application is hereby filed. Utility Model Content

[0008] Furthermore, the plug-in terminal includes a second plug-in portion that can slide vertically along the inside of the plug-in slot, the second plug-in portion has a second connecting portion connected to the top end, the second connecting portion has a first connecting portion connected to the top end, the first connecting portion is connected to the first plug-in portion at one end away from the second connecting portion, and the second plug-in portion is vertically arranged to the first plug-in portion.

[0009] Furthermore, grooves are formed on the left and right side walls of the second connection portion, and a protrusion is integrally formed on the inner side wall of the plug-in slot, and the protrusion can be snapped into the interior of the groove.

[0010] Furthermore, the second connecting portion has limiting portions formed on both left and right side walls, and the limiting portions on both sides are symmetrically arranged.

[0011] Furthermore, a support portion is formed on the top surface of the rear end shell, and the number of the support portions corresponds to the number of the plug-in slots.

[0012] Furthermore, the material of the protective shell can be any one of plastic, rubber or ceramic.

[0013] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art.

[0014] In the utility model, by providing a protective shell on the outside of the plug-in terminal, on the one hand, the plug-in terminal can shield the part exposed to the outside after installation, thereby playing a shielding and protective effect, preventing the plug-in terminal exposed to the outside from being easily oxidized, resulting in poor contact, and poor conductivity, which will also bring hidden dangers to future use. On the other hand, when the plug-in terminal is installed, the protective shell can play an insertion guiding effect on the plug-in terminal, thereby avoiding positional displacement of the plug-in terminal during the plug-in installation process.

[0028] like Figures 1 to 5 As shown, the utility model provides a terminal structure.

[0029] Specifically, by Figure 1-Figure 5 It is given, including a plug-in terminal 1; a protective shell 2 for protecting the plug-in terminal 1 is arranged on the outside, the protective shell 2 includes a front end shell 201 and a rear end shell 202 fixedly connected to each other, a plurality of plug-in slots 204 are spaced apart between the front end shell 201 and the rear end shell 202, and the plug-in terminal 1 is plugged into the inside of the plug-in slot 204.

[0030] In the utility model, by providing a protective shell 2 on the outside of the plug-in terminal 1, on the one hand, the plug-in terminal 1 can shield the part exposed to the outside after installation, thereby playing a shielding and protective effect, preventing the plug-in terminal 1 exposed to the outside from being easily oxidized, resulting in poor contact, and poor conductivity, which will also bring hidden dangers to future use. On the other hand, when the plug-in terminal 1 is installed, the protective shell 2 can play an insertion guiding effect on the plug-in terminal 1, thereby avoiding positional displacement of the plug-in terminal 1 during the plug-in installation process. Installation in this way can reduce the scratch between the plug-in terminal 1 and the electrical equipment, and avoid the tin plating on the outer surface of the plug-in terminal 1 from being scratched and falling off during the installation process.

[0031] Furthermore, as a specific implementation of the present invention, the present invention provides a terminal structure.

[0032] Specifically, Figure 3 It is shown that the plug-in terminal 1 includes a second plug-in portion 104 that can slide vertically along the inside of the plug-in slot 204, the second plug-in portion 104 is connected to the second connecting portion 103 at the top, the second connecting portion 103 is connected to the first connecting portion 102 at the top, the first connecting portion 102 is connected to the first plug-in portion 101 at one end away from the second connecting portion 103, and the second plug-in portion 104 is vertically arranged with the first plug-in portion 101.

[0033] Furthermore, as another specific implementation of the present invention, the present invention provides a terminal structure.

[0034] Specifically, Figure 3-Figure 5 It is shown that grooves 105 are formed on the left and right side walls of the second connecting portion 103 , and a protrusion 205 is integrally formed on the inner side wall of the plug-in slot 204 . The protrusion 205 can be snapped into the inside of the groove 105 .

[0035] In the present invention, the connection between the plug-in terminal 1 and the protective shell 2 is more stable through the groove portion 105 provided at the second connecting portion 103 and the protrusion portion 205 provided inside the plug-in slot 204 .

[0036] Furthermore, as a specific implementation of the present invention, the present invention provides a terminal structure.

[0037] Specifically, Figure 1-Figure 3 It is shown that the limiting portions 106 are formed on both the left and right side walls of the second connecting portion 103, and the limiting portions 106 on both sides are symmetrically arranged.

[0038] In the utility model, the width of the upper part of the second connecting part 103 is increased by setting the limiting part 106, so that the width of the upper part of the second connecting part 103 is greater than the width of the plug-in slot 204, so that when the second connecting part 103 is inserted into the plug-in slot 204, the bottom surface of the limiting part 106 can fit with the upper open end surface of the plug-in slot 204, thereby achieving a limiting effect and preventing the second connecting part 103 from being completely inserted into the plug-in slot 204.

[0039] Furthermore, as a specific implementation of the present invention, the present invention provides a terminal structure.

[0040] Specifically, Figure 1 and Figure 4 It is shown that a support portion 203 is formed on the top surface of the rear end shell 202 , and the number of the support portions 203 corresponds to the number of the plug-in slots 204 .

[0041] In the present invention, after the plug-in terminal 1 is connected to the protective shell 2, the support portion 203 is arranged to fit the outer wall of the plug-in terminal 1 to provide support, thereby further improving the stability of the connection between the plug-in terminal 1 and the protective shell 2.

[0042] Furthermore, as a specific implementation of the present invention, the present invention provides a terminal structure.

[0043] Specifically, Figure 1 It is noted that the material of the protective shell 2 can be any one of plastic, rubber or ceramic.

[0044] The utility model has good insulation performance and plays a good protective effect.

[0045] Working principle: By setting a protective shell 2 on the outside of the plug-in terminal 1, on the one hand, the plug-in terminal 1 can shield the exposed part to the outside after installation, thereby playing a shielding and protective effect, avoiding the exposed plug-in terminal 1 from being easily oxidized, resulting in poor contact, and poor conductivity, which will also bring hidden dangers to future use. On the other hand, when the plug-in terminal 1 is installed, the protective shell 2 can play an insertion guiding effect on the plug-in terminal 1, avoiding the position displacement of the plug-in terminal 1 during the plug-in installation process. This installation method can reduce the scratch between the plug-in terminal 1 and the electrical equipment, and avoid the tin plating on the outer surface of the plug-in terminal 1 from being scratched and falling off during the installation process.
