Connector and forming method of connector
View Patent ↗A connector comprises an insert-molded body. The insert-molded body comprises a housing and a terminal partially embedded in the housing. The housing has a main portion. The main portion is formed with a trace hole and an accommodation space. The terminal has a held portion, a bent-back portion extending forward from the held portion, a support portion extending rearward from the bent-back portion and a contact portion supported by the support portion. The held portion has a wide portion. When the insert-molded body is seen from above, the wide portion is, at least in part, visible through the trace hole. Each of the support portion and the contact portion has a size smaller than that of the wide portion in the lateral direction. The wide portion is partially visible through the accommodation space when the insert-molded body is seen from below.
1. A connector configured to be pressed against an object to be connected to the object, wherein:
the connector comprises an insert-molded body;
the insert-molded body comprises a housing made of resin and a terminal;
the terminal is partially embedded in the housing;
the housing has a main portion;
the main portion has an upper surface and a lower surface in an upper-lower direction;
the lower surface of the main portion faces the object when the connector is connected to the object;
the main portion is formed with a trace hole and an accommodation space;
the trace hole extends downward from the upper surface of the main portion;
the accommodation space is recessed upward from the lower surface of the main portion;
the terminal has a held portion, a bent-back portion, a support portion and a contact portion;
the held portion extends in a front-rear direction perpendicular to the upper-lower direction and is held by the housing so as to face, at least in part, the accommodation space;
the held portion has a wide portion;
when the insert-molded body is seen from above, the wide portion is, at least in part, visible through the trace hole;
the bent-back portion extends forward from the held portion;
the support portion extends rearward from the bent-back portion and is resiliently deformable;
the contact portion is supported by the support portion;
the support portion and the contact portion are located under the held portion;
each of the support portion and the contact portion has a size smaller than that of the wide portion in a lateral direction perpendicular to both the front-rear direction and the upper-lower direction;
the support portion is partially accommodated in the accommodation space;
the wide portion has opposite sides in the lateral direction each of which protrudes beyond the support portion in the lateral direction; and
the wide portion is partially visible through the accommodation space when the insert-molded body is seen from below.
2. The connector as recited in claim 1 , wherein:
the connector is connectable to a cable;
the terminal has a solderable portion and an embedded portion;
the solderable portion is configured to be soldered to the cable; and
the embedded portion is located between the solderable portion and the held portion and is entirely surrounded by the housing in a plane defined by the upper-lower direction and the lateral direction.
3. The connector as recited in claim 2 , wherein:
the embedded portion has a bent portion;
the bent portion is bent in the upper-lower direction; and
the solderable portion and the held portion are apart from each other in the upper-lower direction.
4. The connector as recited in claim 1 , wherein the support portion has an end which is a free end and is located in the accommodation space.
5. The connector as recited in claim 1 , wherein;
the housing is formed with a passing hole;
the passing hole passes through the main portion from the upper surface to the lower surface and communicates with the accommodation space; and
the bent-back portion is located in the passing hole.
6. The connector as recited in claim 1 , wherein;
the insert-molded body comprises an insert-shell made of metal; and
the insert-shell is partially embedded in the housing and is partially exposed from the lower surface of the main portion.
7. The connector as recited in claim 6 , wherein the insert-shell surrounds the contact portion in a horizontal plane perpendicular to the upper-lower direction when the connector is connected to the object.
8. The connector as recited in claim 1 , wherein;
the connector comprises a cover made of metal; and
the cover covers, at least in part, an upper surface of the insert-molded body.
9. The connector as recited in claim 8 , wherein;
the insert-molded body is formed with a first hole;
the cover is formed with a second hole;
the second hole corresponds to the first hole in a horizontal plane perpendicular to the upper-lower direction; and
the connector is screwed to the object with a screw inserted into the first hole and the second hole when the connector is used.
