[0003] In order to ensure the reliability of the circuit, the combined upper shell and lower shell need to be reliably located inside the shielding case to prevent the terminal from shaking during the plugging and unplugging process. Utility Model Content

[0004] The purpose of the utility model is to provide a wiring terminal to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wiring terminal, comprising a conductive terminal and a connecting terminal connected to the conductive terminal; a shielding cover is provided on the outside of the conductive terminal, and an electrical contact point is also provided on the outer wall surface of the shielding cover; an outer cover body is also provided on the connecting terminal, and after the outer cover body is sleeved on the outside of the shielding cover, the electrical contact point is in conflict with the inner wall surface of the outer cover body; an upper shell and a lower shell for clamping a conductive plate are also provided inside the shielding cover, and a buckle is also provided on the shielding cover, and the buckle is used to connect with the upper shell and the lower shell to fix the combined upper shell and the lower shell in the shielding cover.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.

[0019] Please refer to Figures 1-6The utility model provides an embodiment: a terminal block, comprising a conductive terminal 30 and a connecting terminal 31 connected to the conductive terminal 30; a shielding cover 319 is provided on the outside of the conductive terminal 30, and an electrical contact point 320 is also provided on the outer wall surface of the shielding cover 319; an outer cover body 325 is also provided on the connecting terminal 31, and after the outer cover body 325 is sleeved on the outside of the shielding cover 319, the electrical contact point 320 conflicts with the inner wall surface of the outer cover body 325; an upper shell 32 and a lower shell 33 for clamping a conductive plate are also provided inside the shielding cover 319, and a buckle 322 is also provided on the shielding cover 319, and the buckle 322 is used to connect with the upper shell 32 and the lower shell 33, so as to fix the combined upper shell 32 and the lower shell 33 in the shielding cover 319.

[0020] In summary, by optimizing the structure of the shielding cover 319, that is, setting a buckle 322 on the outside of the shielding cover 319, the combined upper shell 32 and the lower shell 33 can be reliably located in the shielding cover 319, and then the electrical contact point 320 is used to contact the inner wall surface of the outer cover body 325 to increase the flow area between the conductive terminal 30 and the connecting terminal 31, thereby reducing the heat generation when the equipment is in use.

[0021] Specifically, since the electrical contact points 320 are distributed on the four outer wall surfaces of the shielding cover 319, and each outer wall surface has two electrical contact points 320, the flow area can be further increased to reduce the heating phenomenon when the equipment is in use; wherein, the electrical contact points 320 are processed on the shielding cover 319 through a stamping process, and at the same time, the electrical contact points 320 are arched and protrude from the outer wall of the shielding cover 319, so when they come into contact with the outer cover body 325, they are also elastic to ensure the tightness of the two after the connection.

[0022] Furthermore, since the shielding cover 319 is also provided with an outward-tilted card plate 323, the outward-tilted card plate 323 can be used to clamp into the plug housing 1 to ensure that the conductive terminal 30 can be reliably fixed in the plug housing 1, thereby ensuring that the conductive terminal 30 is stably and reliably connected to the plug housing 1. The combined upper housing 32 and lower housing 33 can be reliably connected to the shielding cover 319, thereby ensuring that the terminal block will not slip during the insertion and removal process.

[0023] On the basis of the above scheme, since a pressing sheet 321 is also provided on the shielding cover 319, during the insertion process of the plug housing 1 and the mating housing 2, the pressing sheet 321 can be used to guide the two to dock smoothly. After the docking is completed, the pressing sheet 321 can be used to squeeze the mating housing 2 to further improve the stability of the two after connection.

[0024] Further, an isolation plate 324 is further provided on a side of the shielding cover 319 away from the connection terminal 31. Therefore, the structural strength of the end face of the shielding cover 319 can be enhanced by using the pressing piece 321, and at the same time, the pressing piece 321 can be used to make a certain gap between the shielding cover 319 and the plug housing 1, thereby facilitating the timely removal of heat.

[0025] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations to these embodiments still fall within the protection scope of the present invention.
