(4) The abutting portion 244 is provided at the upper end of the first vertical portion 241, and the horizontal plane of the abutting portion 244 is parallel to the horizontal plane of the insulating main body 1, so that the abutting portion 244 and the insulating main body 1 are in plane-to-plane contact, rather than point-to-plane or line-to-plane contact, the supporting arm 24 and the insulating main body 1 can be in contact with each other more stably, and the supporting arm 24 is not prone to tilt.
(5) The abutting portion 244 is located at the lower end of the second vertical portion 242, the second vertical portion 242 abuts against the chip module 200 upwards, the first vertical portion 241 and the second vertical portion 242 are located on the same vertical plane, the first vertical portion 241 and the second vertical portion 242 are connected only through the abutting portion 244, so that the support arm 24 does not have a long inclined portion, and the first vertical portion 241 and the second vertical portion 242 are not bent laterally in the horizontal direction, the support arm 24 has good rigidity, and is not easy to bend or shift left and right when supporting the chip module 200.
(6) The two support arms 24 and the one contact portion 224 electrically contact the same contact pad 400, and a connecting line of three contact points with the contact pad 400 forms a triangle, since the triangle may form a plane, three contact points formed by each terminal 2 may support the chip module 200 on a horizontal plane, and compared with the case where the three contact points formed by the two support arms 24 and the one contact portion 224 with the contact pad 400 are located on the same straight line, the three contact points formed by each terminal 2 may not support the chip module 200 on a stable plane, at least two terminals 2 are required to support the chip module 200 together to stabilize the chip module 200 on a plane, so that it is required that the flatness of any two terminals 2 is good, the chip module 200 can be supported smoothly only with higher accuracy, a triangle is formed by connecting three contact points of each terminal 2 and the chip module 200, so that the terminal 2 and the contact pad 400 can be stably contacted at multiple points, and the accuracy requirement of the flatness of the terminals 2 does not need to be particularly high.
The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all technical changes that can be made by applying the present specification and the drawings are included in the scope of the present invention.
