The specific embodiment is as follows:
the utility model will be further described with reference to specific examples and figures.
Embodiment one:
as shown in fig. 3 to 7, the charging combination terminal according to the first embodiment includes: a plug-in part 1, a connecting part 2 and an elastic conductive part 3.
The plug-in part 1 is used for being in butt joint with an external conductive pin (column), so the front end of the plug-in part 1 is provided with a plug-in interface 11, and the external conductive pin (column) is inserted into the plug-in interface 11 in the butt joint process. In order to ensure a stable high-current conduction between the plug interface 11 and the conductive pins (posts), elastic conductive clips 4 are installed in the plug interface 11. Specifically, the elastic conductive clip 4 is an unclosed surrounding sleeve, a positioning groove 111 is formed on the inner wall of the plug interface 11, and the elastic conductive clip 4 is limited in the positioning groove 111 under the action of self elastic expansion.
The rear end of the plug-in part 1 is provided with a conductive adapting part 12, in the first embodiment, the conductive adapting part 12 is a boss formed at the rear end of the plug-in part 1, and the bottom surface of the boss forms elastic conductive contact with the elastic conductive part 3.
The plug part 1 also forms a first limit flange 13, and in the first embodiment, the first limit flange 13 is matched with an external plastic base in the assembling process of the charging gun, so that the plug part 1 is prevented from being separated from the plastic base under the action of plug force.
The connecting part 2 is used for connecting external conductive components (such as plug terminals connected with wires in a charging gun), the connecting part 2 is usually fixed in a plastic base of the charging gun in an integrated mode, and an adapting groove 21 sleeved with the conductive adapting part 12 is formed at the front end of the connecting part. The adapting groove 21 is mainly used for installing the elastic conductive part 3, and meanwhile, the adapting groove 21 can be in sleeved fit with the conductive adapting part 12. The rear end of the connecting part 2 is provided with a connecting hole 22 connected with an external conductive component.
Similarly, a second limiting flange 23 is formed on the connecting portion 2, and in this embodiment, in the assembling process of the charging gun, the connecting portion is fixedly connected with the plastic base through the second limiting flange 23 and the external plastic base.
The plug part 1 is provided with a first through hole 110 communicated with the plug interface 11; the connecting portion 2 is provided with a second through hole 220 communicated with the connecting hole 22. The first through hole 110 and the second through hole 220 may form an air hole in the plugging fit, which is beneficial to plugging.
The elastic conductive part 3 is installed in the adapting groove 21 in a limiting way and is in conductive contact with the connecting part 2. Referring to fig. 7, the elastic conductive part 3 in this embodiment is integrally formed as a dome shape with a notch 30, and includes: a base band 31 in the form of a non-closed loop and a plurality of elastic arms 32 integrally formed with the base band 31 and spaced apart from each other. The elastic arm 32 extends from the bottom strip 31 toward the plug-in part 1, and is inclined toward the annular center direction enclosed by the bottom 31 while extending, and then the end of the elastic arm 32 is directed toward the center direction by bending toward the center direction. The bottom of the bottom strip 31 is serrated.
The adapting groove 21 has an opening 211 matching with the conductive adapting portion 12 and a cavity 212 for accommodating the elastic conductive portion 3, the diameter of the opening 211 is smaller than that of the cavity 212, so that the adapting groove 21 forms a shape of a small opening and a large belly, when the elastic conductive portion 3 is assembled, firstly, the elastic conductive portion 3 is compressed towards the center by the notch 30 of the elastic conductive portion 3, so that the shape diameter enclosed by the whole elastic conductive portion 3 is reduced, and the elastic conductive portion can smoothly pass through the opening 211; next, when the elastic conductive part 3 is placed in the cavity 212, the external force acting thereon disappears, and under the self-elasticity, the whole elastic conductive part 3 expands to the periphery, so that the outer surface of the bottom strap 31 is attached to the inner wall of the cavity 212 by self-expansion.
Embodiment two:
as shown in fig. 8 and 9, the difference between the second embodiment and the first embodiment is that: the connecting portion 2 in the first embodiment is processed in an integrally molded manner. The connecting portion 2 in the second embodiment includes: the main body 201 and the collar 202, and the fitting groove 21 is formed by a cavity surrounded by the collar 202.
The main body 201 and the collar 202 in the second embodiment are independent from each other, so that the processing difficulty can be reduced. When assembled, the main body 201 and the collar 202 are nested by the step parts, that is, the step parts 204 are formed at the front end of the main body 201 and the rear end of the collar 202. In addition, in order to further position the elastic conductive portion 3, a protruding portion 203 is formed on the top surface of the front end of the main body portion 201, and a gap for accommodating the bottom tape 31 is formed between the protruding portion 203 and the collar portion 202.
The working principle of the first and second embodiments is described with reference to fig. 8 and 9, since the first and second embodiments have the same structure except for the difference in the processing manner of the connecting portion 2. When the charging gun is adopted, in the process of butting the external conductive pins (columns) with the plugging interfaces 11 in the plugging part 1, the plugging part 1 is subjected to pressure along the axial direction in the process of external force insertion, the plugging part 1 generates certain displacement under the action of the pressure, and the size of the displacement can be set by forming a fit clearance with an external plastic base through the first limit flange 13. The pressure received by the plug-in part 1 is transferred to the elastic conductive part 3, and the elastic conductive part 3 is elastically deformed by the pressure of the conductive adapting part 12 as follows:
(1) The non-closed ring shape enclosed by the bottom strip 31 expands outwards under pressure, the outer surface of the bottom strip is expanded to be tightly fit with the inner wall of the adaptation groove 21, at the moment, the bottom strip 31 is tightly fit with the inner wall of the adaptation groove 21 under the action of pressure, and a conductive contact surface is formed between the bottom strip 31 and the inner wall of the adaptation groove 21;
(2) The bottom of the bottom strip 31 is pressed against the bottom surface of the adapter groove 21 under pressure, while the bottom of the bottom strip 31 is serrated or shaped similarly thereto, so that it is ensured that at least a multi-point conductive contact is present.
(3) The elastic arm 32 is bent in the center line direction under pressure, so that the highest point of the elastic arm 32 is pressed against the bottom surface of the boss constituting the conductive fitting part 12. Because the whole elastic conductive part 3 is provided with a plurality of elastic arms 32, under the action of pressure, each elastic arm 32 can realize conductive contact with the bottom surface of the boss of the conductive adapting part 12, and the elastic arms 32 form a plurality of parallel branches, so that the conductive contact is stable, and the high-current charging operation is facilitated.
By adopting the elastic guide portion 3, since the elastic guide portion is expanded in the circumferential direction during operation, a long elastic compression space is not required in the axial direction, and stable elastic support can be provided in a short distance, thereby ensuring the stability of conductive contact. Meanwhile, the plug-in part 1 and the connecting part 2 are connected through the elastic guide connection part 3, so that surface contact guide connection and multipoint guide connection can be realized, and the problem that screw thread guide connection is easy to generate is avoided.
Embodiment III:
on the basis of the first and second embodiments, the elastic conductive part 3 can be deformed according to the present utility model, as shown in fig. 10, the elastic conductive part 3 in the third embodiment is a conductive metal sheet with an arch bulge, and the bulge direction of the conductive metal sheet faces the conductive adapting part 12; the bottom of the adapting groove 21 is formed with a clamping groove 210 for clamping the edge of the conductive metal sheet. The elastic conductive part 3 is elastically deformed by the pressure of the conductive fitting part 12 as follows: the raised part of the conductive metal sheet has a reduced height tendency under pressure, so that the raised part is pressed against the bottom surface of the boss forming the conductive adapting part 12, and surface contact is formed between the raised part and the conductive adapting part 12 so as to adapt to the large current passing. The edges of the conductive metal sheet are pressed against the card slot 210 under pressure. Other structures of the third embodiment are the same as those of the first and second embodiments, and the functional effects are the same, which will not be described in detail herein.
It is understood that the foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, but rather is to be accorded the full scope of all such modifications and equivalent structures, features and principles as set forth herein.
