Abstract

A connector is mateable with an object along a front-rear direction. The connector comprises a housing, a shell and an additional member. The housing has a base portion and a body portion. The body portion extends forward from the base portion along the front-rear direction. The shell has a cylindrical portion which covers the body portion of the housing in a plane perpendicular to the front-rear direction. The cylindrical portion has a connected portion. The additional member is press-fit in the base portion of the housing and has a main portion and a connection portion. The connection portion of the additional member extends from the main portion along the front-rear direction and is welded to the connected portion of the shell. The body portion of the housing and the connection portion sandwich the connected portion in a perpendicular direction perpendicular to the front-rear direction.

the lock portion is received in the receiving portion.

2. The connector as recited in claim 1, wherein:

the holding member of the internal assembly has a received portion; and

the received portion is received in the receiving portion.

3. The connector as recited in claim 2, wherein the lock portion of the shell is positioned rearward of the received portion within the receiving portion.

4. The connector as recited in claim 1, wherein the cylindrical portion of the shell has a rear edge which is in abutment with the base portion.

5. The connector as recited in claim 1, wherein the connector is mounted on a circuit board when used.

6. The connector as recited in claim 5, wherein:

the base portion of the housing is formed with two first holes;

each of the first holes pierces the base portion in the front-rear direction;

each of the additional members is formed with a second hole;

the second holes pierce the additional members in the front-rear direction, respectively;

the first holes correspond to the second holes, respectively; and

the connector is attachable to the circuit board via screwing in which the first holes and the second holes are used.

7. The connector as recited in claim 6, wherein:

the second holes are formed in the main portions of the additional members, respectively;

the connector is attachable to the circuit board via the screwing in which two screws pass through hole sets, respectively, wherein each of the hole sets includes one of the first holes and one of the second holes corresponding to each other; and

when the connector is attached to the circuit board via the screwing of the screws, head of each of the screws fastens the main portion of one of the additional members against the base portion together with the main portion of a remaining one of the additional members.

8. The connector as recited in claim 5, wherein:

the base portion of the housing is formed with a positioning hole;

the positioning hole pierces the base portion in the front-rear direction;

the shell has a fixed portion;

the fixed portion passes through the positioning hole; and

the fixed portion is fixed to the circuit board when the connector is mounted on the circuit board.

9. A connector mateable with an object along a front-rear direction, the connector comprising a housing, an internal assembly, a shell and two additional members, wherein:
