Connector preventing occurrence ofsolderwicking up from surface mount portion thereof
View Patent ↗A connector includes terminals, a holding portion made of insulating resin, and a housing. Each of the terminals has a surface mounting technology (SMT) portion, a spring portion, a contact point, and a connection portion. The SMT portion is soldered to an object. The holding portion is directly held by the housing. The housing has accommodation portions which accommodate the spring portions of the terminals, respectively, and a barrier wall which separates two of the accommodation portions which are adjacent to each other. The connector is configured to prevent occurrence of solder wicking up from the SMT portion when the SMT portion is soldered to the object.
1. A connector comprising:
a plurality of terminals;
a holding portion made of an insulating resin; and
a housing,
wherein:
each of the terminals has a surface mounting technology (SMT) portion, a spring portion, a contact point, and a connection portion;
the SMT portion is to be soldered when the connector is mounted on an object;
the spring portion has resilience;
the contact point is supported by the spring portion;
the spring portion and the SMT portion are apart from each other in a predetermined direction;
the connection portion connects the spring portion and the SMT portion to each other;
the connection portion has a held portion extending at least in the predetermined direction;
the held portion is embedded in the holding portion at least in part so that the holding portion holds the held portion;
the holding portion is directly held by the housing;
the housing has a plurality of accommodation portions which accommodate the spring portions of the terminals, respectively, and a barrier wall which separates two of the accommodation portions which are adjacent to each other, and
the holding portion comprises a plurality of holding pieces which correspond to the terminals, respectively, and are separated from each other.
2. The connector as recited in claim 1 , wherein:
the connector defines a mating direction directed upward in an up-down direction; and
the holding portion is press-fit into the housing from beneath in the up-down direction.
3. The connector as recited in claim 2 , wherein:
the housing has a protection portion; and
the protection portion hides the spring portion in part when viewed from above in the up-down direction.
4. The connector as recited in claim 1 , wherein:
the connector defines a mating direction directed upward in an up-down direction; and
the holding portion hides the held portion when viewed from beneath in the up-down direction.
5. The connector as recited in claim 1 , wherein:
the connector defines a mating direction directed upward in an up-down direction;
the predetermined direction is the up-down direction; and
the holding portion holds an entire periphery of the held portion in a plane perpendicular to the predetermined direction.
6. The connector as recited in claim 1 , wherein the housing and the holding portion are both made of a same insulating resin material.
7. The connector as recited in claim 1 , wherein the housing is made of an insulating resin material which is different from a material of which the holding portion is made.
