Technical field

The present invention relates to the snap-in structures between a kind of terminal and lance shape element, and wherein terminal, which is accommodated in, is set to shell Terminal accommodating chamber.

Background technique

In the past, it is known that the terminal for connecting live wire is inserted in the end that the shell of connector is arranged in by a kind of connector In sub- accommodating chamber (die cavity), and the lance shape element (elastic locking piece) of the elastically deformable by forming in terminal accommodating chamber and end Subcard closes, so that terminal is contained in terminal accommodating chamber (for example, patent document 1).

Summary of the invention

The technical problem to be solved by the invention

In technology described in Patent Document 1, the locking protrusion of terminal and through hole are provided in the box-shaped portion of terminal Wall portion, the locking protrusion of terminal reach through hole.Also, the end face of the through hole side of the locking protrusion of terminal and the engaging portion of lance shape element Engaging.However, being formed with through hole in wall portion, and the end side of the transverse direction of terminal (width direction) is provided with connection wall Portion, that is, there are connection wall portions.Therefore, the transverse direction that the engaging portion in lance shape element is set on the basis of considering to connect wall portion is (wide Spend direction) size, so the engaging size between the engaging portion of lance shape element and the locking protrusion of terminal narrows, and engage area Become smaller.Therefore, when pulling force is applied to the electric wire for being connected to terminal, it is possible to cannot ensure that there is foot to terminal by lance shape element Enough retentivities.

The present invention makes in view of the foregoing, and the purpose is to provide a kind of can be improved to be contained in the terminal of shell The connector of the retentivity of the terminal of accommodating chamber.

For technical means to solve problem

To solve the above-mentioned problems and realize goal of the invention, connector of the invention is characterized in that: being had and is connected with electricity The terminal and shell of line, the shell have housing body, and the housing body has terminal accommodating chamber, the terminal accommodating chamber The direction orthogonal with front-rear direction section be rectangle, the terminal accommodating chamber is by antetheca, roof, two opposed walls and bottom wall It shapes, opposed in the orthogonal up and down direction of front-rear direction, described two opposed walls exist for the roof and the bottom wall Opposed in the orthogonal width direction of front-rear direction and up and down direction, the bottom wall has the elastically deformable for being attached at base portion Lance shape element, the lance shape element have the locking side of the front side towards the direction of insertion as the terminal, and the terminal has Box-shaped portion and interconnecting piece, the section in the direction orthogonal with front-rear direction in the box-shaped portion are rectangle, and the box-shaped portion has top Plate, two opposed plates and bottom plate, the top plate and bottom plate are opposed in the up-down direction, and described two opposed plates are in the direction of the width Opposed, the top plate at least has front top plate, and the front top plate utilizes in described two opposed plates and reaches each opposed plate outer surface Notch shape, the front top plate has towards the engaged face of detaching direction, that is, rear side as the terminal, In the state that the terminal is accommodated in the terminal accommodating chamber, the locking side is in the width direction greater than described two right It sets and is engaged in the range of two opposed plate inner surface width of plate with the engaged face.

In addition, the engaged face of the front top plate includes horizontal engaged face in the connector；And convex Engaged face, the convex are locked locking face in the longitudinal direction by being formed with described in arrival on the front top plate The protrusion in engaged face and protrude along the vertical direction.

In addition, the front top plate is opposed with one in described two opposed plates in the direction of the width in the connector Plate connection, and having from another opposed plate side towards the bottom plate side preceding protrusion outstanding, described another is described opposed Plate has the front recess removed from the top plate side towards the bottom plate lateral incision, and the preceding protrusion is chimeric with the front recess.

In addition, described two opposed walls of the terminal accommodating chamber have from each opposed walls inner surface in the connector The groove being recessed outward in the width direction, the groove are formed in the part opposed with lance shape element side along front-rear direction.

Invention effect

Connector according to the present invention has the retentivity for the terminal that can be improved the terminal accommodating chamber for being contained in shell Effect.
