When the conventional base head 300 is soldered to other electronic components, tin forms a solder ball at the solder leg of the base head signal terminal 310, the solder ball flows onto the base head signal terminal sleeve portion 320, and the communication performance of the base head signal terminal 310 is affected due to poor conductivity of tin.

Accordingly, referring to fig. 1 to 4 and fig. 12, the present embodiment discloses a reliable solder resist-based head 300, including:

a base insulator 340 and a plurality of base signal terminals 310; each base head signal terminal 310 comprises a welding part 330 extending out of the base head insulator 340, and the welding part 330 is welded with other electronic elements to realize the transmission of electric signals; when the soldering portion 330 is soldered, due to the arrangement of the solder-blocking portion, the solder ball formed on the soldering portion 330 of the base header signal terminal 310 by the tin is blocked by the first solder-blocking portion 345, and the solder ball does not flow onto the socket portion of the base header signal terminal 310 along the body of the signal terminal, so that the signal transmission performance of the base header signal terminal 310 is better and the reliability is high.

Preferably, the first solder resist 345 is disposed on the header insulator 340, and the first solder resist 345 is attached to a surface of the soldering portion 330 facing the mating body and a side surface along a first direction, where the first direction is an arrangement direction of the plurality of header signal terminals 310. In an operation scenario, the base 200 is horizontally placed, the base 300 is inserted into the base 200 along a third direction, the third direction is a gravity direction of the base 300, one surface of the soldering portion 330 facing the butt-joint body is a bottom surface of the soldering portion 330, accordingly, the bottom surface and two side surfaces of the soldering portion 330 are attached to the first solder blocking portion 345, and when the soldering portion 330 is soldered to other electronic components by using solder, the solder 400 formed on the soldering portion 330 does not flow into the signal terminals through the bottom surface and the side surfaces of the soldering portion 330, and the signal transmission performance of the signal terminals is not affected.

Preferably, the first solder barrier 345 on each of the header signal terminals 310 is integrally formed, so that the header insulator 340 has higher strength and is more stably connected to the header signal terminals 310. In addition, the base head insulator 340 adopting the scheme has the advantages of simple and compact structure, simpler manufacturing process and cost saving.

Further preferably, the first solder barrier 345 is integrally formed to simultaneously adhere to the soldering portion 330 and the first connecting portion 321 of each of the base signal terminals 310, so as to form a structure similar to a reinforcing rib, so that the strength of the base insulator 340 is higher and the connection with the base signal terminals 310 is more stable.

Preferably, the base head 300 further includes a second solder resisting portion 346 connected to the first solder resisting portion 345, the second solder resisting portion 346 is attached to a surface of the soldering portion 330 facing away from the butt-joint body and/or is attached to a surface of the first connecting portion 321 facing the second connecting portion 323, a surface of the soldering portion 330 facing away from the butt-joint body is a top surface of the soldering portion 330, and the first solder resisting portion 345 and the second solder resisting portion 346 are attached to a periphery of the soldering portion 330, so that the solder ball can be further blocked, and the solder ball is prevented from entering the signal terminal to affect transmission performance of the signal terminal.

Preferably, the base head 300 further includes a third solder resist 347 connected to the second solder resist 346, the third solder resist 347 is attached to a surface of the second connecting portion 323 facing the first connecting portion 321, and the first connecting portion 321 of the base head signal terminal 310 is a portion directly contacting the base signal terminal 270, and needs to be protected for enhancing signal transmission performance, so that the third solder resist 347 is disposed on a side of the first connecting portion 321 facing the soldering portion 330, which can further ensure a solder resist effect of the base head 300.

Further preferably, in the direction in which the base head 300 is inserted into the docking body (the third direction), at least a portion of the third solder resist 347 is located higher than the second solder resist 346, especially when the second solder resist 346 is attached to only one surface of the first connecting portion 321 facing the second connecting portion 323. Accordingly, even if some solder balls are not blocked by the first solder blocking portions 345 and the second solder blocking portions 346, as long as the third solder blocking portions 347 are located higher than the second solder blocking portions 346, the solder balls do not contact the second connection portions 323 beyond the third solder blocking portions 347 under the action of gravity, and the signal transmission performance of the base header signal terminal 310 is good.

Example 4 the rest of the structure and the operation principle are the same as those of example 3.

When the base head 300 is connected to the base 200, a soldering space 500 is formed between the soldering portion 330 and the base 200, the soldering portion 330 is soldered to another electronic component in the soldering space 500, and a part of the solder balls is blocked in the soldering space. Furthermore, the arrangement of the soldering space means that the soldering portion 330 of the base signal terminal 310 is a free end, which is not supported by other objects, and if the length is longer, it is easy to tilt up or down, and therefore, the base 300 having the high-strength signal terminal provided in embodiment 3 can be used to stabilize the structure of the connector 100.
