Problems solved by technology
[0010] However, in the electronic components described in the above-mentioned Patent Document 1 and Patent Document 2, in which a predetermined object to be inserted is inserted through the insertion opening, when it is used, the card or the connector on the object side is inserted into the insertion opening. etc., so the load is applied in all directions centered on the insertion direction, which causes peeling of the welded part of the metal case
[0011] Therefore, a high peel strength is required for the welded portion of the metal case. However, in the card connector of Patent Document 1, only measures against the residual stress generated by heating during soldering are implemented, and the peel strength of the welded surface itself cannot be achieved. strengthen
[0012] In addition, since the composite connector of Patent Document 2 adopts the central mounting method, it is particularly easy to bear the load in the direction perpendicular to the circuit board, that is, in the direction that promotes the peeling of the soldered surface, and only the solder of the leg extending from the metal shell is used. Soldering cannot obtain sufficient peel strength

Embodiment Construction
[0041] (the whole frame)
[0042] according to Figure 1 to Figure 6 The connector 10 which is an electronic component which is an embodiment of the present invention will be described. figure 1 is a perspective view of the connector 10, figure 2 is the side view, image 3 is along figure 1 Cross-sectional view of the X-X line.
[0043] The connector 10 is a so-called center-mounted connector provided in a state where an edge portion of a circuit board stored in a housing of an electrical product fits into a notch. In addition, the connector 10 is a receptacle connector conforming to the Micro-B standard called USB (Universal Serial Bus), and includes an insertion opening for inserting a plug connector (not shown).
[0044] The connector 10 includes a terminal holding portion 30 holding five connection terminals 20 , .
[0045] Hereinafter, the insertion direction of the plug connector with respect to the insertion opening of the metal housing 40 of the connector 10 is ...

The invention provides an electronic component for raising durability of stripping load of the electronic component relative to a circuit board. The electronic component is provided with a terminal keeping part for keeping a plurality of terminals (20) and a metal shell (40) which is provided with the terminal keeping part in the inner side and forms an inserting opening for inserting into connecting objects of the terminals. A side part (42) of the metal shell is provided with a plate-shaped foot part (47) for fixing the metal shell on the circuit board by welding; the plate-shaped foot part extends to the external part from the metal shell and has a welding surface of an extending end in the following shape: a base part (S1) extending along an extending direction and orthogonal extension parts (S2,S3) orthogonal with the base part from side parts and extending along inserting directions of the inserting opening.
Description
technical field [0001] The present invention relates to an electronic component provided with an insertion opening. Background technique [0002] Examples of electronic components that have a metal case that forms an insertion opening for a predetermined object and are mounted on a circuit board by soldering include card connectors and the like, digital signal input and output, and power input and output. connectors etc. [0003] For example, the existing card connector has a housing that holds a plurality of terminals in a parallel state, and a metal case that surrounds the housing with side and top parts to form an insertion opening for inserting a card. The flat part on the front end side of the hanging piece extending outward in a state where the part hangs down is used as a soldering surface to be mounted on a circuit board (for example, refer to Patent Document 1). [0004] In addition, in this card connector, in order to reduce the influence of thermal expansion and...
