Fig. 1 is an exploded view of a connector according to some embodiments of the present application, fig. 2 is a longitudinal sectional view of the connector in fig. 1, and fig. 3 is a sectional view a-a of the connector in fig. 2. The connector comprises a connecting seat 1, a needle shaft 2 and an elastic component 3.
The connecting holder 1 comprises a holder hole 11, one end of the holder hole 11 is provided with a hole 111, the other end is formed with a stop wall 12, and the hole wall of the holder hole 11 comprises a first contact surface 112 formed by stamping or forging.
As shown in fig. 2, the connection seat 1 is a needle tube, and the seat hole 11 is a tube hole of the needle tube. The connecting base 1 is designed as a needle tube, so that the size of the connecting base 1 in the radial direction of the base hole 11 can be reduced, and the occupied space of the connecting base 1 is reduced.
The needle shaft 2 extends into the seat hole 11 from the opening 111 and is in sliding fit with the seat hole 11, the peripheral wall 21 of the needle shaft 2 comprises a second contact surface 22 formed by stamping or forging, and the second contact surface 22 is in surface contact with the first contact surface 112.
The elastic member 3 is disposed in the seat hole 11 and connected between the stopper wall 12 and the needle shaft 2, and the elastic member 3 can apply an elastic force to the needle shaft 2 to slide in a direction away from the connecting seat 1.
The material of the connecting seat 1 and the needle shaft 2 may be brass, but is not limited thereto, and other conductive materials may be used. The diameter of the hole 111 is smaller than the diameter of the seat hole 11, so as to prevent the needle shaft 2 and the elastic component 3 from being separated from the connecting seat 1. In assembling, the elastic member 3 and the needle shaft 2 are sequentially inserted into the seat hole 11, and finally, a necking process is performed at one end of the seat hole 11 to form the orifice 111.
In the connector, the second contact surface 22 and the first contact surface 112 are in surface contact, so that the contact area between the connecting seat 1 and the needle shaft 2 is increased, the contact impedance is obviously reduced, and the high-current passing capacity of the connector is favorably improved.
Because the second contact surface 22 and the first contact surface 112 are formed by stamping or forging, the limitation of the turning on the types of the contact surfaces between the connecting seat 1 and the needle shaft 2 is broken through, and the second contact surface 22 and the first contact surface 112 can be made into the required types according to actual needs, so that the contact area between the second contact surface 22 and the first contact surface 112 is favorably increased, the contact impedance is reduced, and the passing capacity of large current of the connector is improved.
In addition, compared with the turning process, the second contact surface 22 and the first contact surface 112 can avoid generating excessive waste during the manufacturing process, which is beneficial to improving the utilization rate of materials.
In some embodiments, as shown in fig. 2 and 3, the first contact surface 112 is a concave curved surface and the second contact surface 22 is a convex curved surface and mates with the first contact surface 112.
Because the first contact surface 112 and the second contact surface 22 are curved surfaces which are matched in a concave-convex manner, slippage between the first contact surface 112 and the second contact surface 22 can be avoided, so that the first contact surface 112 and the second contact surface 22 are in close contact, the contact impedance of the two is reduced, and the signal and current transmission performance of the connector can be further improved.
In some embodiments, as shown in fig. 2 and 3, the radii of curvature of the first and second contact surfaces 112, 22 at the point of contact are equal.
The first contact surface 112 and the second contact surface 22 can be matched by the design, so that the first contact surface 112 and the second contact surface 22 can be completely attached together, which is beneficial to further increasing the contact area between the first contact surface 112 and the second contact surface 22 so as to reduce the contact resistance of the two.
The first contact surface 112 and the second contact surface 22 may also be a curved surface, a paraboloid, an elliptic curved surface, etc., and are not limited herein.
In some embodiments, as shown in fig. 2 and 3, the seat hole 11 is a kidney-shaped hole (also called a runway hole), and the cross section of the part where the needle shaft 2 is matched with the seat hole 11 is kidney-shaped.
Through the design, the seat hole 11 can better limit the needle shaft 2, and the needle shaft 2 is prevented from rotating in the seat hole 11, so that the second contact surface 22 of the needle shaft 2 is in closer contact with the first contact surface 112 of the seat hole 11, and the contact resistance of the two is further reduced.
Of course, the surface contact form between the needle shaft 2 and the seat hole 11 is not limited to the above embodiment, and other surface contact forms are possible.
In some embodiments, as shown in fig. 1 and 2, the elastic member 3 includes an abutting member 31 and a spring 32, the abutting member 31 is an insulating member and abuts against the end surface 23 of the needle shaft 2 extending into the seat hole 11; a spring 32 is connected between the abutment 31 and the stop wall 12.
By designing the abutting member 31 as an insulating member, it is possible to prevent a current from flowing through the spring 32, thereby avoiding a failure caused by a serious heat generation (low conductivity due to a small wire diameter of the spring) of the spring 32 when a large current is passed therethrough.
In some embodiments, as shown in fig. 1 and 2, the abutment 31 is spherical and abuts one end of the spring 32.
By designing the abutment 31 in the shape of a sphere, it is facilitated that the abutment 31 is mounted between the spring 32 and the needle shaft 2.
Of course, the contact member 31 may be designed to have other shapes such as a cylindrical shape, instead of the spherical shape.
In some embodiments, as shown in fig. 2, the end surface 23 of the needle shaft 2 is a slant surface and includes a proximal end 231 close to the first contact surface 112 and a distal end 232 far from the first contact surface 112, and the proximal end 231 is tilted relative to the distal end 232 in a direction close to the stopper wall 12.
As shown in fig. 2, by providing the end surface 23 as an inclined surface, the abutment member 31 exerts a force F perpendicular to the end surface 23 on the needle shaft 2 under the elastic force of the spring 32, and this force F can be resolved into a vertical upward component FYWith a horizontal leftward component FxThereby, the second contact surface 22 on the needle shaft 2 is tightly contacted with the first contact surface 112 to reduce the contact resistance of the two.
