Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, a metal contact and a test terminal according to the present invention are described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Example one

Referring to fig. 1-2, the present embodiment provides a metal contact, including a base 100;

two sides of the base 100 are provided with contact pieces 210, and the two groups of contact pieces 210 are oppositely arranged to form a contact assembly 200; the contact pieces 210 of the contact assembly 200 are provided with contact protrusions 211, and the contact protrusions 211 on the two groups of contact pieces 210 are opposite; at least two sets of contact assemblies 200 are disposed on two sides of the base 100. Through set up the contact assembly 200 more than two sets of in base 100 both sides, make the stability of metal contact obtain improvement by a wide margin, when the test, the area greatly increased of test needle 300 and metal contact, even one of them group of contact assembly 200 takes place to warp, the contact assembly 200 of other groups also can compensate for can both effectively discern the test piece when the test terminal inserts at every turn, has ensured rapid detection's efficiency.

In this embodiment, the contact pieces 210 are elastic pieces, so that the test pin 300 can be conveniently clamped between the contact pieces 210 at two sides, and the test pin 300 can be clamped due to the elastic force of the contact pieces 210 after the test pin is clamped, thereby facilitating the insertion and extraction test.

In this embodiment, the contact protrusion 211 is a hemisphere, the contact protrusions 211 on the two inner sides of the contact assembly 200 just can abut against the testing needle 300, and the hemispherical arrangement can make the contact surface smoother, thereby preventing scratching and abrasion.

In this embodiment, the base 100 and the contact assembly 200 are made of copper or copper alloy, the copper has high conductivity and is easy to machine and mold, and the strength is moderate, so as to satisfy the design of the contact assembly 200.

In this embodiment, contact assembly 200 is equipped with two sets ofly, because the size of terminal plastic part has certain restriction, and is preferred, contact assembly 200 sets up two sets ofly, can ensure that contact protrusion 211 area is certain on every contact assembly 200 of group, can play the problem of avoiding one of them group of contact assembly 200 contact failure discernment to fail again.
