Definitions
- the present invention relates to a latch structure that holds engagement when a connector is fitted.
- Patent Document 1 JP-A-6-236781
- Patent Document 2 JP-A-7-192810
- the present invention relates to an engagement member when a first connector to which a conductive member is connected and a second connector having a contact and electrically connected to a substrate are engaged, and the engagement member is a longitudinal member.
- the first arm portion having two arm portions extending in the axial direction and engaging with the corresponding connector engaging portion includes a first projecting portion extended to the second arm portion side, and a connector rod.
- a second projecting portion extending outward in the insertion direction, and the second arm portion has a stopper supported by a support portion extended outward in the connector insertion direction, The stopper abuts when the first arm portion is bent to the outside of the connector to stop the bending, and the first protrusion locks the engaging portion of the corresponding connector by staking the tension in the longitudinal axis direction. Furthermore, the second projecting portion is formed when the first arm is bent in the opposite direction to the second arm.
- Such a stopper is in contact with the first arm portion and the contact portion that contacts the second projecting portion. It has a contact part. Therefore, the movement of the first arm can be restricted. Further, the first arm has a taper that guides the engaging portion when the engaging portion of the corresponding connector is latched. Further, the first arm or the second arm is formed of an elastic member, and the first arm bends at the time of latching, whereby the engagement can be made smooth. Furthermore, by providing such a latch structure symmetrically on the left and right sides of the connector, it is possible to realize a latch that can hold the connector engagement more reliably.
- FIG. 1 is a perspective view of an engaging portion corresponding to a latch member of the present invention.
- FIG. 2 is a perspective view of a connector provided with a latch member of the present invention.
- FIG. 3 is a perspective view of a connector latched by a latch member of the present invention.
- Fig. 4 is a cross-sectional view taken along the line A- in Fig. 3. (a) shows a state where no force is applied to the connector, and (b) shows a state where the first arm is in contact with the stagger. FIG.
- FIG. 5 is a perspective view of the connector shown in FIG. 3 as viewed from the opposite side, that is, from below. Explanation of symbols
- FIG. 1 is a perspective view of the latch member of the present invention. First, each member will be described. In the perspective view of FIG. 1, the first arm 1 extends from the back of the figure toward the front, and the tip extends downward to form the first protrusion 3. ing. Further, a second projecting portion 4 is formed by extending substantially vertically in the left direction of the drawing.
- the first arm 1 has a longitudinal axis
- the first arm 1 has a taper 8 that guides the engaging portion 7 of the corresponding connector when engaged.
- a first protrusion 3 extends from the end of the first arm 1 in a direction substantially perpendicular to the longitudinal axis of the arm, and the first protrusion 3 extends from the end of the first protrusion 3.
- the second projecting portion 4 extends substantially perpendicular to the longitudinal axis direction of 3.
- the second arm 2 positioned below the first arm 1 extends in parallel with the first arm 1 from the back to the front in the figure.
- a connecting portion 6 extending in the left direction in the figure is formed at the tip of the second arm 2, and a stagger 5 is formed in the connecting portion 6.
- the stopper 5 is a flat plate-like member extending upward from the connecting portion 6 as shown in FIG.
- the second arm 2 extends with a longitudinal axis parallel to the first arm 1 and is substantially perpendicular to the longitudinal axis and substantially parallel to the second protrusion 4.
- a connecting portion 6 extending in the direction is formed.
- a stopper 5 is connected to the connecting portion 6, and the stopper 5 is formed in a flat plate shape and substantially parallel to the first arm 1 and the second arm 2.
- FIG. 2 shows a perspective view of the whole connector including the second arm 2, the connecting portion 6, and the stopper 5.
- the latch member 11 is installed symmetrically on the left and right of the second connector 12.
- the second arm 2 and the connecting part 6 are continuously formed in an “inverted L shape” in this figure.
- the connecting portion 6 further extends in the direction of the stopper 5 and is continuously connected to the stopper 5 shown in the latch member 11 on the right side of the second connector 12 in FIG. That is, the three members of the second arm 2, the connecting portion 6, and the stopper 5 are integrally formed.
- Figure 5 shows this situation from another angle.
- Fig. 5 is a view of the entire connector including the conductive member 11 from the bottom, with force S, and as shown in Fig. 5, the second arm 2, the connecting portion 6, and the stopper 5 are a single body. I understand that
- the first arm 1 and the second arm 2 are connected to each other, and the first arm 1 and the second arm 2 use the latch member as a connector housing.
- Each is connected to a fixing part 9 for fixing. Therefore, the fixed portion 9 is shared and connected to each other.
- FIG. 2 is a view when the latch member 11 is attached to the second connector 12.
- the fixing portion 9 of the latch member 11 is attached to the second connector 12, and the latch member 11 is attached symmetrically to both the left and right sides of the second connector 12.
- the first connector is inserted into the second connector 12.
- the corresponding engaging portion of the first connector is engaged with the latch member 11.
- the engaging and latching operations will be described with reference to FIGS.
- the end of the first connector opposite to the conductive member 16 is first inserted into the second connector.
- the first connector is rotated and fitted to the second connector using the inserted end as a fulcrum.
- the engaging portion 7 moves downward and comes into contact with the taper 8.
- the engaging portion 7 presses the first arm 1 toward the stopper 5 and causes it to bend.
- the engaging member 7 moves downward as it is, and the engaging surface 10 contacts the lower surface of the first arm 1, that is, the surface facing the second arm 2. The engagement is thus completed.
- FIG. 3 When removing the connector, move the first arm 1 to the outside, The engagement between the engaging portion 7 and the first arm 1 is released by pushing the pad 5 toward the side. At this time, stress due to bending is applied to the first arm 1. Further, when the first arm 1 is formed of an elastic member or the like, it may be deformed or damaged due to excessive or repeated force. At this time, when the stagger 5 comes into contact with the first arm 1, the movement of the arm 1 is restricted, and deformation and breakage due to excessive force can be prevented. When this is viewed in FIG. 4 showing a cross-sectional view taken along the line AA ′ of FIG.
- the engaging portion 7 is not displaced in FIG. 4A and is engaged with the first arm 1.
- the state shown in FIG. 4 (b) is obtained.
- the first arm 1 is expanded to the left in the figure, but is in contact with the stopper 5, and the stopper 5 restricts the movement.
- the stagger 5 is slightly bent outward, and this bending generates a drag force on the first arm, so that the movement of the first arm 1 is substantially restricted.
- the latch 14 in the front-rear direction 14 of the connector will be described. It will be apparent to those skilled in the art that the movement is restricted by the housing with respect to the force in the direction of pushing the conductive member 16 toward the connector in FIG.
- a force for pulling out the connector works.
- the engaging portion 7 of the second connector moves according to the tension.
- the engaging portion 7 shown in FIG. 3 comes into contact with the first protruding portion 3 of the latch member. Since the latch member 11 is fixed to the housing, the first protrusion 3 does not move in the longitudinal axis direction.
- FIG. 4 is a cross-sectional view taken along the line A— in the figure, in FIG. 4A, a part of the engaging portion 7 is located in the longitudinal axis direction of the second arm 2 and the first arm 1 or the second arm Located on the same plane as 2. Therefore, when the engaging portion 7 moves to the near side with respect to FIG. 4A, the movement is restricted by the first projecting portion 3 (not shown in FIG. 4A) and the engagement is held.
