A conventional wire connector plug 10 includes a first contact member n, a second contact member 12, a third contact member u, a fourth member, and the contact members U, 12, and 13 Electrically isolated from 14 = 15. The first contact member u includes a contact portion η 〇 and an extension portion lu extending from the contact portion, and the extension portion lu includes a second-order portion, a neck portion 1112, and a second column portion. The first column body UU and the second column body portion 1112 are both cylindrical, and the diameter of the first column body 1111 is larger than the diameter of the second column body portion 1113. The neck portion 1112 has a truncated cone shape whose diameter gradually decreases from the first cylindrical portion 11U toward the second cylindrical portion (10). The total length of the first cylinder portion mi and the neck lii2 is 2.4 mm. The first, second, third, and fourth contacts 12, 13 and 14 respectively include an annular contact portion 12〇, 13〇 and 14〇 and an extension from the circular-shaped contact portions 120, 130 and 140 Annular extensions 124, 134 and 144. The second, third and fourth contacts 12, 13 and 14 are sequentially sleeved on the extensions 111, 124 and 134 of the previous contacts 11, 12 and 13 of 6 1305968, and the first, second and third The extensions 114, 124, 134 and 144 of the fourth contacts 11, 12, 13 and 14 are disposed coaxially. In addition, the extensions 114, 124, 134 and the ends of the first, second, third and fourth contacts 11, 12, 13 and 14 are exposed to the outside of the insulator 15, thereby forming the first pad II2, respectively. The second pad 122, the third pad 132 and the fourth pad 142. The first, first, third and fourth pads 112, 122, 132 and 142 are used to solder and form electrical connections with wires (not shown). In the above cable connector plug 10, since the neck portion 1112 of the first contact member U is directly connected to the second column portion 1113, the connection between the two forms an angle with a tip when the cable connector is When the contact portion HO of the plug 1 is subjected to lateral pressure, the stress of the neck 119 and the second cylinder portion m3 connected to the sonar i will concentrate on the missing end of the angle, and when the lateral pressure is lower than the neck The joint between the portion 1U2 and the second cylindrical portion 1113 is prone to poor mechanical strength. I Agricultural Machinery [Summary of the Invention] In the above, it is necessary to provide a cable connector plug having better mechanical strength. A green wire mirror connection II plug includes a first contact piece, the contact member includes a contact portion and an end portion extending from the contact portion, the extension portion sequentially includes a first cylindrical portion, and the opening portion is a body The connection between the first column portion and the second column portion is a smooth transition portion at the junction of the cable connector two-column portion of the prior art, so when the contact portion is subjected to the lateral direction 1305968, The stress applied to the joint between the neck and the second cylinder portion can be dispersed on the arc surface of the joint between the two, so that the joint between the neck and the second cylinder portion can withstand a large stress even if the line money The connector plug has better mechanical strength.
