Abstract

The utility model relates to a terminal carrier tape and an electric connector made of the terminal carrier tape. The terminal carrier tape comprises a carrier and a plurality of terminals connected with the carrier; wherein, each terminal, which has an integrated metal structure, comprises a butted part, a fixed part, a connected part and a welded part; the fixed part is arranged between the butted part and the connected part; the connected part is arranged between the fixed part and the welded part; and the welded part has a U-shaped solder cup structure. When the terminal carrier tape is applied in the electric connector, the welded parts with the U-shaped solder cup structures can fix the welding positions of core wires, increase the contact surfaces of the terminals and soldering tin points and ensure the range of the soldering tin points, moreover, since the connected parts are integrally diffusely distributed, the terminal carrier tape can better reduce the occurrence of adverse phenomena such as rosin joint and even welding, thus enhancing the stability of welding.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

See also Fig. 4 to shown in Figure 7, a kind of terminal material belt 10 comprises carrier 11 and the plurality of terminals 12 that is connected together by carrier 11, and each terminal 12 is the metal material integrated formed structure, wherein:

Above-mentioned each terminal 12 includes docking section 121, fixed part 122, connecting portion 123 and weld part 124, this fixed part 122 is located between docking section 121 and the connecting portion 123, this connecting portion 123 is located between fixed part 122 and the weld part 124, this weld part 124 is U type weldering cup structure, and each connecting portion 124 whole system is the diffused distributed architecture, can reduce effectively to connect and weld the bad phenomenon generation.Wherein U type weldering cup both can play location heart yearn 13 approximate location effects, increase the structural strength of weld part 124 and tin point 14 again and guaranteed that tin puts 14 scopes, subsides tin quantity, make the bonding wire operation convenient, can manual bonding wire, also bonding wire operation automatically is when automatic weld job, can use wire clamp that heart yearn 13 is twined by connecting point position earlier, peeling tin sticky then is placed into heart yearn 13 in the U type weldering cup of correspondence position again, will manage good wire rod and terminal through the soldering tip of heating and weld simultaneously.
