And because the two ends of the insulating elastic member 31 are respectively connected with the metal sleeve 10 and the built-in end 21, the excessive current of the insulating elastic member 31 can be avoided, and the insulating elastic member 31 can be prevented from losing elasticity.

Referring to fig. 5, fig. 5 is a perspective view of a metal sleeve in the probe connector 100 shown in fig. 4. The metal sleeve 10 may include a base 11 and a barrel 12 fixed to the base 11.

The built-in end 21 of the conductive contact 20 is cylindrical and has a diameter equal to that of the accommodating cavity 101, so that the built-in end 21 can contact with the inner wall of the accommodating cavity 101, thereby improving the conductivity of the conductive contact 20 and the metal sleeve 10. The external connection end 22 is cylindrical and has a diameter equal to the inner diameter of the top edge 122, so that the external connection end 22 can penetrate through the top edge 122 and is electrically connected with an external device. In this embodiment, the diameter of the inner end 21 is larger than the diameter of the outer end 22, and the inner end 21 and the outer end 22 are coaxially disposed.

Optionally, one end of the built-in end 21 of the conductive contact 20, which is connected to the insulating elastic member 31, is provided with a connecting surface 211 forming an included angle with a radial plane of the accommodating cavity 101, one end of the insulating elastic member 31 abuts against the connecting surface 211 to support the connecting surface 211 and apply an acting force perpendicular to the connecting surface 211, so that the built-in end 21 of the conductive contact 20 is biased along the axial direction of the metal sleeve 10 and the surface of the built-in end 21 contacts with the inner wall of the accommodating cavity 101, thereby improving the reliability of the electrical connection between the conductive contact 20 and the metal sleeve 10.

With continued reference to fig. 2 and 3, the elastic assembly 30 may further include a metal cap 32 sleeved on the insulating elastic member 31, and the insulating elastic member 31 is connected to the outer terminal 22 of the conductive contact 20 by the metal cap 32.

The insulating elastic member 31 includes a first end 311 and a second end 312, the first end 311 is connected to the bottom plate 111 of the base 11, and the second end 312 is connected to the outer terminal 22. The second end 312 is sleeved with the metal cap 32 and connected with the built-in end 21 of the conductive contact 20 through the metal cap 32. In this embodiment, the insulating elastic member 31 is cylindrical and has a spiral or circular groove 310 formed on a side surface thereof, so that the insulating elastic member 31 can deform along the axial direction, and the conductive contact 20 can reciprocate along the axial direction of the accommodating cavity 101.

The metal cap 32 may include a top plate 321 and a connecting plate 322 extending from an edge of the top plate 321, the connecting plate 322 and the top plate 321 define a fixing cavity 320, and the second end 312 is received and fixed in the fixing cavity 320.

The top plate 321 is provided with a circular arc-shaped top surface 3211, one side of the built-in end 21 facing the metal cap 32 is provided with a connecting surface 211 forming an included angle with the radial plane of the conductive contact 20, the top surface 3211 abuts against the connecting surface 211 and is in point contact with the connecting surface 211, friction between the top surface 3211 and the connecting surface 211 is reduced, the top surface 3211 is easy to move relative to the connecting surface 211, the built-in end 21 of the conductive contact 20 is deviated along the axial direction of the metal sleeve 10, and the surface of the built-in end 21 is in contact with the inner wall of the accommodating cavity 101, so as to improve the reliability of electrical connection between the conductive contact 20 and the metal sleeve 10.

The connecting plate 322 is a cylindrical structure and includes an engaging surface 3221 with a circular cross section, and the engaging surface 3221 can engage with an inner wall of the accommodating cavity 101. Since the metal cap 32 is abutted to the connection surface 211 through the top surface 3211 to realize electrical connection with the conductive contact 20, the abutting surface 3221 abuts to the inner wall of the accommodating cavity 101, and reliability of electrical connection between the conductive contact 20 and the metal sleeve 10 can be further improved.

During assembly, the metal cap 32 is first sleeved on the second end 312 of the insulating elastic member 31, so that the metal cap 32 and the insulating elastic member 31 form the elastic assembly 30. The first end 311 of the insulating elastic element 31 is accommodated in the accommodating cavity 101 from the end of the barrel 12 away from the base 11 and abuts against the bottom plate 111, and the built-in end 21 of the conductive contact 20 is accommodated in the accommodating cavity 101 from the end of the barrel 12 away from the base 11 and abuts against the top surface 3211 of the metal cap 32. Then, a necking tool is used to deform the end of the cylinder 12 away from the base 11 toward the axial direction of the cylinder 12 to generate a top edge 122, that is, the cylinder 12 includes a side plate 121 fixed on the bottom plate 111 and a top edge 122 formed by extending from the end of the side plate 121 away from the bottom plate 111 toward the axial direction of the cylinder 12, so as to constrain the elastic component 30 and the built-in end 21 in the accommodating cavity 101.

The probe connector 100 provided by the embodiment of the application, by enabling the two ends of the insulating elastic member 31 to be respectively abutted against the base 11 and the built-in end 21, can ensure the elastic connection between the conductive contact 20 and the metal sleeve 10, and can prevent the insulating elastic member 31 from losing elasticity due to excessive current. In addition, the metal cap 32 is sleeved on the second end 312 of the insulating elastic member 31, so as to reduce friction between the insulating elastic member 31 and the built-in end 21, and improve reliability of electrical connection between the conductive contact 20 and the metal sleeve 10.
