The header base 111 may have a plate shape. The header base 111 may include an edge part 111a. The edge part 111a of the header base 111 is hookable to the main housing 3 (refer to FIG. 2 ). One surface 111b of the edge part 111a may be in surface contact with the header accommodating part 32 (refer to FIG. 3 ) of the main housing 3 . For example, one surface 111b of the edge part 111a may be fixed to the header accommodating part 32 of the housing 3 by laser welding, and in this case, an inner seal may not be required. Of course, it goes without saying that the inner seal may also be included.

As another example, the header 1 may be mounted to the main housing 3 in such a way that the protruding part 113 is fitted to the inner seal 4 (refer to FIG. 3 ). In this case, a waterproof structure may be implemented in a relatively inexpensive manner. The header base 111 may include a hole for passing and supporting the header terminal 12 .

In other words, the protruding part 113 may completely surround the center plate 112 . With this structure, a resin part 13 to be described later may be provided inside the protruding part 113 . In a state in which the header terminal 12 is mounted on the header body 11 , resin in a liquid state may be injected into the protruding part 113 , and the resin is solidified to form an inner space of the protruding part 113 . of waterproof structure can be implemented. Water entering the inside of the protruding part 113 may be restricted from moving downward by the resin.

The protrusion part 113 may be formed to have a lower height than the center plate 112 . According to this structure, even if the resin in the liquid state is injected into the protruding part 113 , the contact part 12b of the header terminal 12 may remain exposed to the outside.

The terminal guide 114 may protrude from the header base 111 . The terminal guide 114 may protrude in a direction opposite to that of the protruding part 113 . The terminal guide 114 may assist the header terminal 12 to be supported by the header 1 in a wide area. A phenomenon in which the header terminal 12 is shaken by the terminal guide 114 may be reduced. The terminal guide 114 may have a smaller width than the header base 111 . According to such a structure, it is possible to stably support the header terminal 12 while forming the header body 11 compactly.

A plurality of header terminals 12 may be provided. For example, six header terminals 12 may be provided. Based on the center plate 112 , the three header terminals 12 may be provided on one surface, and the other three header terminals 12 may be provided on the other surface. The header terminals 12 provided on the same surface with respect to the center plate 112 may be spaced apart from each other.

The header terminal 12 includes a terminal body 12c, a support part 12a and a contact part 12b formed above the terminal body 12c, and an inclined part formed below the terminal body 12c ( 12d) and a damage prevention part 12e.

The terminal body 12c may be mounted on the header base 111 . The terminal body 12c may be provided in parallel with a direction in which the header 1 is inserted into the header accommodating part 32 (refer to FIG. 4 ) of the main housing. The terminal body 12c corresponds to a central region of the header terminal 12 , and a position and posture may be fixed by the header base 111 . The terminal body 12c may be mounted in a hole provided in the header base 111 .

The support part 12a may be provided above the terminal body 12c and may correspond to a region supported by the center plate 112 . The support part 12a may be seated on the terminal alignment part 112a of the center plate 112 . The terminal alignment part 112a may have a relatively wide upper portion and a relatively narrow lower portion. The support part 12a may be aligned in such a way that it slides downward from the top of the terminal alignment part 112a. For example, in a region where the support part 12a is completely seated on the center plate 112 , the width of the terminal alignment part 112a may be the same as the width of the support part 12a .

The contact part 12b may be formed between the terminal body 12c and the support part 12a. The contact part 12b may contact the plug 2 (see FIG. 3 ). For example, the center plate 112 may enter the plug head 21 (refer to FIG. 3 ), and the contact part 12b may be physically and electrically connected to a plug terminal (not shown) provided in the plug head 21 . can The contact part 12b may have a convex shape in a direction away from the center plate 112 .

The inclined part 12d may extend from the terminal body 12c and be inclined with respect to the longitudinal direction of the terminal body 12c. At an end of the inclined part 12d most spaced apart from the terminal body 12c, the header terminal 12 may contact the contact area C (refer to FIG. 2 ) of the printed circuit board. The angle formed by the inclined part 12d with respect to the terminal body 12c may be changed according to the length at which the header terminal 12 is pressed by the printed circuit board P (refer to FIG. 2 ). For example, while the printed circuit board P is mounted to the connector 100 (refer to FIG. 1 ), the printed circuit board P may be deformed by pressing the header terminal 12 . When the inclination of the header terminal 12 is increased, the header terminal 12 may more stably contact the printed circuit board P by restoring force.

The damage prevention part 12e may be provided to be inclined with respect to the longitudinal direction of the inclined part 12d in the same direction as the inclined direction of the inclined part 12d with respect to the terminal body 12c. For example, in the case of the header terminal 12 shown on the left with reference to FIG. 5 , the inclined part 12d is inclined clockwise with respect to the longitudinal direction of the terminal body 12c, and the The damage prevention part 12e may likewise be inclined clockwise with respect to the inclined part 12d. The damage prevention part 12e may assist the header terminal 12 not to contact the printed circuit board P (refer to FIG. 2 ) through the pointed end. The header terminal 12 may contact the printed circuit board at a connection portion of the inclined part 12d and the damage prevention part 12e.

The header terminals 12 may be sequentially bent. For example, the damage prevention part 12e may be formed first, and then the inclined part 12d may be formed. As another example, the inclined part 12d may be formed first, and then the damage preventing part 12e may be formed.

A step formed between the main body part 2111 and the auxiliary body part 2112 may be connected to the plug body. The plug head body 211 may have an accommodation space (A). A header may be inserted into the accommodation space (A).

The plug head body 211 may include an exposed hole H through which the plug terminal 212 may be exposed toward the receiving space A. The exposed holes H may be formed to correspond to the number of plug terminals 212 . The plug terminal 212 may contact the contact part 12b of the header terminal 12 through the exposed hole H.

The plug terminal 212 may be mounted on the plug head body 211 , and a part thereof may be exposed to the outside. For example, in a direction crossing the direction in which the plug head 21 is inserted into the main housing, the plug terminal 212 may be exposed to the outside of the plug head body 211 .

A width of a region in which the plug terminal 212 is exposed to the outside of the plug head body 211 may increase toward an end of the plug head body 211 that is closer to the header. In other words, the plug head body 211 may have a shape for guiding the header terminal in contact with the plug terminal 212 . For example, the width L1 of the lower end of the plug terminal 212 may be greater than the width L2 of the upper end. According to this structure, while the plug is mounted on the main housing, the plug can be aligned.

The plate guide 213 is formed at one end of the plug head body 211 , has a shape that becomes wider in a direction toward the header, and can guide the entry of the center plate.

The connector according to an embodiment may implement a waterproof structure while stably implementing a stable contact between the connector and the printed circuit board without mounting a separate connector on the printed circuit board, and maintaining a compact volume of the connector.
