Example two

4, an electrical connection assembly 200 provided in this embodiment includes a mounting substrate 210 and the aforementioned metal contact structure 100. The mounting substrate 210 is provided with a first limiting member 201, a second limiting member 202, The third limiting member 203, the fourth limiting member 204, and the guide hole 260 are respectively connected with the metal contact piece to jointly define the six degrees of freedom of the metal piece 110, so as to realize the quick positioning and reliable installation of the metal piece 110.

Please refer to FIG. 5, specifically, the first limiting member 201 abuts against the limiting portion 150 of the metal sheet 110. The first limiting member 201 includes a limiting block 220 protrudingly disposed on the mounting substrate 210, and the limiting block 220 abuts against the limiting portion 150 of the metal sheet 110. The limiting block 220 may have a sheet-like or columnar structure. For example, the cross-sectional shape of the limiting block 220 may include, but is not limited to, any shape such as a circle, a square, a diamond, an ellipse, and a triangle. When the limiting portion 150 includes the first insert 151, the first insert 151 abuts the limiting block 220. Alternatively, when the limiting portion 150 includes the second insert 160, the limiting block 220 is inserted into the limiting card slot formed by the second insert 160 and the metal sheet 110, and is used to align the metal sheet 110 in the first direction, that is, Y Axis direction limit.

Or, in an alternative embodiment, the first limiting member 201 includes an elastic piece 225, please refer to FIG. 6, the elastic piece 225 abuts the limiting portion 150.

It is easy to understand that the first limiting member 201 abuts against the middle of the second side surface 103 of the metal sheet 110, so that the metal sheet 110 is more uniformly stressed and the connection is more reliable.

The second limiting member 202 abuts against the first surface 101 and the second surface of the metal sheet 110. Specifically, the second limiting member 202 includes a limiting post 230, and the limiting post 230 is mounted on the mounting substrate 210. Optionally, the limiting post 230 is provided with a slot 231, and the metal sheet 110 is inserted into the slot 231, The width of the slot 231 is approximately equal to the thickness of the metal sheet 110. When the metal sheet 110 is inserted into the slot 231, the first surface 101 and the second surface respectively abut the inner wall of the slot 231, which can realize the second direction, that is, the Z axis The limit of the direction. It is easy to understand that after the metal sheet 110 is inserted into the slot 231, the two degrees of freedom in the Z-axis direction are restricted. In addition, the limiting column 230 and the first limiting member 201 are respectively disposed on both sides of the metal sheet 110. In this embodiment, the limiting column 230 is disposed close to the first side surface of the metal sheet 110, and the first limiting member 201 is close to the metal sheet 110. The second side surface 103 of the sheet 110 is arranged, so that the slot 231 of the limiting post 230 and the first limiting member 201 jointly limit the two degrees of freedom of the metal sheet 110 in the first direction, that is, the Y-axis direction.

The third limiting member 203 abuts against the first end surface 105 of the metal sheet 110. Specifically, the third limiting member 203 includes a baffle 240 protruding from the mounting substrate 210, the baffle 240 and the metal sheet 110 The first end surface 105 abuts against, and is used to limit the position of the metal sheet 110 in the third direction, that is, the X-axis direction. It is easy to understand that the first end surface 105 is in contact with the baffle 240, the second end 113 of the metal sheet 110 is inserted into the mounting through hole 143 of the third connecting portion 140, and the metal sheet 110 has two free positions in the X-axis direction. The degree is limited.

Optionally, the fourth limiting member 204 includes a supporting block 250, which is fixed on the mounting substrate 210 and disposed opposite to the baffle 240, the first end 111 of the metal sheet 110 abuts the baffle 240, and the other end is placed On the supporting block 250, the supporting block 250 supports the metal sheet 110. The first limiting member 201 and the second limiting member 202 are both disposed between the baffle 240 and the supporting block 250. The limit of the metal sheet 110 can also have other forms. For example, when the bending section 115 of the second end 113 abuts the support block 250, the limit in the X-axis direction can also be realized by the bending section 115. It should be noted that when the metal sheet 110 is placed on the support block 250, the degree of freedom of the metal sheet 110 in the negative direction of the Z-axis is restricted, and the second limiting member 202 may only be provided with a stop surface for contacting the metal sheet. The first surface 101 of the 110 resists to limit the degree of freedom of the metal sheet 110 in the positive direction of the Z axis. For example, a stopper piece is protrudingly provided on the side of the stopper 230 facing the metal sheet 110, and the stopper piece abuts against the first surface 101 of the metal sheet 110, and is used to align the metal sheet 110 in the second direction, that is, the Z-axis direction. Limit. Similarly, a card slot can also be provided on the baffle 240, and the first end 111 of the metal sheet 110 is inserted into the card slot, which can limit the two degrees of freedom of the metal sheet 110 in the Z-axis direction and the degree of freedom in the negative X-axis direction. Alternatively, the support block 250 is provided with a protrusion 251, and the metal sheet 110 is placed on the support block 250. When the first side surface of the metal sheet 110 abuts the protrusion 251, the degree of freedom in the negative direction of the Y axis can be restricted. Of course, it is not limited to this. There are many ways to limit the six degrees of freedom of the metal sheet 110, and the structure of the first limiting member 201, the second limiting member 202 and the third limiting member 203 can also be various. There is no specific limitation here.

The mounting substrate 210 is provided with a guide hole 260, and the first connecting portion 120 can pass through the guide hole 260 and move along the guide hole 260. Specifically, the first connecting post 123 of the first connecting portion 120 passes through the guide hole 260 to achieve electrical connection with the first to-be-connected component. The guide hole 260 is substantially L-shaped, which can facilitate the movement of the metal sheet 110 along the X-axis and the Y-axis on the mounting substrate 210 during installation.

The specific assembly method of the electrical connection assembly 200 is:

First, move the metal sheet 110 along the positive direction of the Y-axis toward the negative direction, so that the metal sheet 110 is locked into the slot 231 of the limit post 230. When the metal sheet 110 moves to the first side surface and the protrusion on the support block 250 When 251 resists, it indicates that it is installed in place in the first direction. Then move the metal sheet 110 along the positive direction of the X-axis toward the negative direction, so that the first end surface 105 of the metal sheet 110 abuts against the baffle 240. When the metal sheet 110 moves until the first end 105 abuts against the baffle 240, It is indicated that the third direction is installed in place, and then the first insert 151 is abutted against the limiting block 220, and finally a bolt is inserted into the installation through hole 143 of the third connecting portion 140 to fix. In this way, the six degrees of freedom of the metal sheet 110 are all restricted. It is easy to understand that the first connecting column 123 moves in the guide hole 260 during the installation and movement of the metal sheet 110. After the metal sheet 110 is installed, the connecting contact of the first connecting post 123 is electrically connected to the first to-be-connected piece, the connecting contact of the second connecting post 135 is electrically connected to the second to-be-connected piece, and the installation of the third connecting portion 140 A bolt is installed in the through hole 143, and the third connecting portion 140 is electrically connected with the third part to be connected by the bolt, and the bolt also plays a fixing role.
