The electronic components and the electronic components of the circuit board mounted on the plug connector side are electrically connected to each other.

Further, at this time, the convex portion protruding from each of the socket contacts is engaged with the concave portion recessed on the surface of each plug contact. Therefore, the operator who performs the connection work of the socket connector and the plug connector by hand can obtain a click feeling when the socket connector and the plug connector are completely connected.

Further, when the convex portion of each socket contact is protruded from the concave portion recessed on the surface of each plug contact, the plug-side fixing metal fitting comes into contact with the elastic contact piece of the socket-side fixing metal fitting.

[Patent Document 1] Japanese Patent Laid-Open Publication No. 2012-9373

In the connector of Patent Document 1, when the convex portion of the socket contact is engaged with the concave portion recessed on the surface of the plug contact (when the socket connector and the plug connector are connected), the socket side is opposite to the socket side. The elastic contact piece of the fixed metal fitting is fixed by the metal fitting on the plug side.

However, at this time, the elastic contact piece of the socket side fixing metal fitting generates an elastic pressure in a direction in which the plug connector is disengaged from the socket connector.

Therefore, there is a spring pressure generated by the elastic contact piece of the metal fitting of the socket side, and the connection of the plug connector and the socket connector is released.

In addition, when the socket connector and the plug connector are connected, the socket contacts The convex portion of the contact portion contacts the smooth surface of the plug contact member, thereby being elastically deformed by the free state, and elastically deforms in a direction toward the free state side when the convex portion of the plug is engaged with the concave portion of the plug contact. Then, by the elastic force when the socket contact member is elastically deformed (restored) toward the free state side, the operator can feel the click feeling when the convex portion of the socket contact is engaged with the concave portion of the plug contact.

The socket contact sub-system has the largest amount of elastic deformation when its convex portion contacts the smooth surface of the plug contact. However, since the contact object of the convex portion at this time is the surface of the plug contact, the amount of elastic deformation of the socket contact at this time is less likely to become larger. Therefore, the elastic force (restoring force) of the socket contactor toward the free state side when the convex portion of the socket contact is engaged with the recess of the plug contact portion is less likely to become larger. Therefore, the click feeling of the socket contact portion when the convex portion of the socket contact is engaged with the recess of the plug contact portion is less likely to be large, and the operator cannot clearly recognize that the convex portion of the plug contact has been engaged with the recess of the socket contact ( Connect the socket connector and the plug connector completely.)

SUMMARY OF THE INVENTION An object of the present invention is to provide a connector which is easy to hold a connection state of a socket connector and a plug connector, and which can be clearly felt by an operator when connected.

And an elastically deformable socket contact member for supporting the socket insulator and a socket metal member for supporting the socket insulator; and a plug connector having a fitting recess a plug insulator of the annular fitting convex portion, a circuit pattern that can be attached to the plug-side circuit substrate, and the fitting convex portion is fitted to the socket contact portion to be in contact with the socket contact portion Insulator contact And supporting the metal fitting on the plug side of the plug insulating member, the connector is characterized in that: the socket contact has a socket side protrusion, and the plug contact has a plug side protrusion, and the fitting protrusion is embedded When the fitting recessed portion is engaged with the socket-side projection, the protruding portion protrudes beyond the socket side toward the fitting direction of the fitting recessed portion, and the plug-side fixing metal fitting is at least one The plug-side protrusion is not in contact with the socket-side fixing metal fitting before the protrusion on the socket side, and when all of the plug-side projections protrude over the socket side, the socket-side fixing metal fitting is in contact with the socket-side fixing The metal fitting includes a metal fitting-side elastic deformation portion that is elastically deformable in an orthogonal direction orthogonal to the fitting direction, and the plug-side fixing metal fitting causes the above-mentioned plug-side projection to protrude over the socket side The metal fitting side elastic deformation portion elastically deforms while contacting the metal fitting side elastic deformation portion.

The socket contact member may include: a first elastic deformation portion that is extended to the fitting direction by one end side of the outer peripheral wall and elastically deformable in the orthogonal direction; and the first elastic deformation portion An extension portion extending in the orthogonal direction at an end portion in the fitting direction; and a first elastic deformation portion extending from a distal end of the extension portion toward a direction in which the fitting convex portion extends in the fitting recess portion a second elastic deformation portion that is elastically deformable in the orthogonal direction in the orthogonal direction, and the socket-side projection includes a first protrusion from the first elastic deformation portion toward the second elastic deformation portion a socket side protrusion and a second socket side protrusion protruding from the second elastic deformation portion toward the first elastic deformation portion side, wherein the plug side protrusion is provided when the fitting convex portion is fitted to the fitting recess portion The first plug-side protrusion and the second plug-side protrusion protruding over the first socket-side protrusion and the second socket-side protrusion, respectively, and the first elastic deformation portion The second portion is elastically deformed The orthogonal direction distance between the first plug-side protrusion and the second plug-side protrusion in the free state is longer than the orthogonal direction distance between the first socket-side protrusion and the second socket-side protrusion.

At this time, the position of the first socket side protrusion and the second socket side protrusion in the fitting direction and the position of the first plug side protrusion and the second plug side protrusion in the fitting direction may be shifted from each other.

The plug insulating member may further include a latching recess, and the socket insulator may be provided with a latching protrusion for contacting the plug contact and the socket when the fitting protrusion is fitted in the fitting recess The above-mentioned fastening recess is fitted to the first contact.

The outer peripheral wall may have a rectangular shape having a pair of short side forming portions and a pair of long side forming portions, and the socket side fixing metal fitting may have a direction in which the short side forming portion is extended along the short side forming portion.

At this time, the metal fitting side elastic deformation portion of the socket side fixing metal fitting is elastically deformed, but the elastic deformation direction is orthogonal to the fitting direction of the fitting convex portion with respect to the fitting concave portion. Therefore, at this time, the elastic pressure generated in the elastic deformation portion of the metal fitting side does not form the elastic pressure in the direction in which the plug connector is disengaged from the socket connector.

Therefore, it is easy to maintain the connection state of the socket connector and the plug connector.

Further, when the socket connector is connected to the plug connector, all of the plug-side projections of the plug contact protrude beyond the socket side corresponding to the socket contact in the fitting direction.

When the plug side protrusion is intended to protrude over the socket side, the amount of elastic deformation of the socket contact is maximized. Then, the connection target of the socket-side protrusion at this time (not the smooth surface of the plug contact) is the plug-side protrusion, so the amount of elastic deformation of the socket contact at this time is (the connection object with the socket-side protrusion is the plug contact) The smooth surface is larger when compared to). Therefore, when the plug-side projection completely protrudes over the socket side, the socket contact sub-system is deformed toward the plug contact side side with a strong elastic force (recovery force), and the socket-side projection side contacts (impacts) the plug contact with a large force. The surface of the child.

Therefore, when the socket connector and the plug connector are connected, the operator does feel a click feeling, and it is possible to clearly recognize that the socket connector and the plug connector are connected.

The socket connector 35 having the above structure is formed on a circuit board 70 (a rigid board, a socket side circuit board, and a imaginary line of the twelfth figure) which are formed in parallel with the circuit board 34 (including substantially parallel) a circuit pattern (not shown) for mounting the surface, soldering the tail piece 61 of each socket contact 60, and further, for each of the conduction sensing patterns formed on the mounting surface, each soldering The short-side tail piece 53 of the metal fitting 50 and the lower end portion of the long-side tail piece 54 are fixed to the socket side, whereby the circuit board 70 is fixed (constructed) (so-called straight (ST) connection). Other electronic components (for example, a CPU, a controller, a memory, etc.) different from the receptacle connector 35 are attached to the mounting surface of the circuit board 70.

The plug connector 15 and the receptacle connector 35 constructed as above are connected in the following manner.

First, as shown in the eleventh and twelfth drawings, the operator (not shown) holds the plug connector 15 and the receptacle connector 35 by hand while making the front and rear positions and the left and right positions coincide with each other. At the same time, the plug connector 15 and the receptacle connector 35 are opposed to each other in the up-down direction.

Next, the plug connector 15 is moved downward, the fitting convex portion 18 is fitted to the fitting concave portion 44, and the engaging concave portion 19 is fitted to the engaging convex portion 43. As a result, the left and right guide inclined faces 18a of the plug insulator 16 of the plug connector 15 abut against the left and right rounded faces 43a of the snap projections 43 of the receptacle connector 35, and the left and right guide inclined faces 18b abut. It is connected to the inclined surface 42a2 of the left and right contact convex portions 42a1.

Further, when the plug connector 15 is moved downward, the left and right guide inclined faces 18a of the plug insulator 16 of the plug connector 15 are directed to the left and right inclined guide faces 43b of the snap projections 43 of the receptacle connector 35. The lower side slides, and the left and right guide inclined surfaces 18b slide downward on the surfaces of the left and right contact convex portions 42a1. That is, the guiding inclined surface 18a and the inclined guiding surface 43b and the guiding inclined surface 18b are guided by the contact convex portion 42a1, so that the plug connector 15 smoothly moves in the fitting direction (downward) with respect to the socket connector 35. . In this manner, since the entire upper portion of the engaging convex portion 43 is fitted to the entire lower portion of the engaging recessed portion 19, the plug connector 15 and the receptacle connector 35 are substantially movable only in the vertical direction (strictly speaking, It may be different from the up and down direction A state in which the direction is slightly moved and the amount of the clearance between the outer circumferential surface of the engaging convex portion 43 and the inner circumferential surface of the engaging concave portion 19 is small.

As described above, the latching recess 19 and the latching projection 43 are connected to each other after the plug connector 15 and the receptacle connector 35 are relatively moved in the up-down direction (there is no relative rotation). When the device 15 is further moved downward, as shown in the thirteenth (a), the lower end portion of each plug contact 25 of the plug connector 15 is opposite to the lower portion 64 and the rising portion of each socket contact 60 of the receptacle connector 35. The upper end of 66 is contacted by the upper side. As shown in the thirteenth (b) diagram, at this time, the plug-side fixing metal fitting 28 of the plug connector 15 is separated upward by the socket-side fixing metal fitting 50 of the receptacle connector 35.

When the plug connector 15 is moved downward by the state of the thirteenth diagram, the lower end portions of the plug contact members 25 of the plug connector 15 enter between the hanging portion 64 of each socket contact member 60 and the rising portion 66, The elastic contact piece 63 is elastically deformed in such a manner that the opening 64 is spaced apart from the rising portion 66.

Next, the first plug-side protrusion 26b1 of each plug contact 25 is engaged with the first socket-side protrusion 64a of the hanging portion 64 of each socket contact 60 by the side, and the second plug-side protrusion of each plug contact 25 The second socket-side projection 66a of the rising portion 66 of 26a1 is engaged with the upper portion. In this way, the circuit substrate 34 and the circuit substrate 70 can be electrically connected through the plug contact 25 and the socket contact 60. When the plug connector 15 is moved downward in this state, as shown in Fig. 14, the first plug-side projection 26b1 faces downward (the fitting direction of the fitting convex portion 18 with respect to the fitting recess 44) over the first The socket side protrusion 64a, the first socket side protrusion 64a contacts the surface of the outer contact piece 26b, and the second plug side protrusion 26a1 is engaged with the second socket side protrusion 66a of the rising portion 66 by the side. At this time, the plug-side fixing metal fitting 28 of the plug connector 15 is connected to the socket side of the receptacle connector 35. The fixing metal fitting 50 is separated upward.

When the plug connector 15 is slightly moved downward by the state of the fourteenth diagram, the second plug-side projection 26a1 of each plug contact 25 passes over the second socket-side projection 66a of the rising portion 66 downward, and the second socket side protrudes. 66a contacts the surface of the inner contact piece 26a (the state shown in the figure between the fourteenth and fifteenth figures is omitted). At this time, the plug-side fixing metal fitting 28 of the plug connector 15 is also separated upward by the socket-side fixing metal fitting 50 of the receptacle connector 35.

When the first plug-side protrusion 26b1 of each plug contact 25 is engaged with the first socket-side protrusion 64a of the hanging portion 64 of each socket contact 60, and the second plug-side protrusion 26a1 of each plug contact 25 is relatively raised When the second socket-side projection 66a of the 66 is engaged (instantaneously), the amount of elastic deformation of the elastic contact piece 63 (the hanging portion 64, the extension portion 65, and the rising portion 66) of the socket contact 60 is maximized. Next, the connection target of the first socket-side protrusion 64a and the second socket-side protrusion 66a at this time is (not a smooth surface of the plug contact 25). The first plug-side protrusion 26b1 and the second plug-side protrusion of the plug contact 25 are. 26a1, therefore, the amount of elastic deformation of the elastic contact piece 63 at this time (compared to when the connection object is a flat surface) becomes large. Therefore, when the first plug-side projection 26b1 completely passes over the first socket-side projection 64a, the vertical lower 64 is deformed toward the outer contact piece 26b side with a strong elastic force (restoring force), and the first socket-side projection 64a is side. The surface of the outer contact piece 26b is contacted (impacted) with a large force (refer to Fig. 14). Similarly, when the second plug-side projection 26a1 completely passes over the second socket-side projection 66a, the rising portion 66 is deformed toward the inner contact piece 26a side with a strong elastic force (restoring force), and the second socket-side projection 66a The surface of the inner contact piece 26a is contacted (impacted) with a large force. Therefore, the operator does feel a click feeling, and it is possible to clearly recognize that the plug connector 15 and the receptacle connector 35 have been connected.

After that, if the plug connector 15 is moved further downward, as shown in the fifteenth figure It is to be noted that the rounded surface 30a of the plug-side fixing metal fitting 28 of the plug connector 15 is in contact with the contact protrusion 56 of the metal fitting-side elastic deformation portion 55 of the socket-side fixing metal fitting 50. The conduction sensing pattern of the circuit board 34 and the conduction sensing pattern of the circuit board 70 are electrically connected to the conduction sensing circuit (not shown), so that the rounded surface 30a of the plug-side fixing metal fitting 28 contacts the socket-side fixing metal. When the contact portion 56 of the accessory 50 is contacted, the identifiable plug connector 15 is connected to the receptacle connector 35 (the second socket-side projection 66a of the receptacle contact 60 is in contact with the inner side of the first receptacle-side projection 64a contacting the plug contact 25 The sheet 26a and the outer contact piece 26b, whereby the circuit pattern of the circuit board 34 and the circuit pattern of the circuit board 70 are electrically connected to each other).

As shown in the sixteenth and seventeenth embodiments, when the plug connector 15 is moved downward by the state of the fifteenth diagram, the inner contact piece 26a of the plug contact 25 and the outer contact piece 26b are opposed to the socket. The second socket side protrusion 66a of the 60 slides with the first socket side protrusion 64a, and the plug connector 15 is completely connected to the socket connector 35.

As a result, the contact portion 30 of the plug-side fixing metal fitting 28 causes the corresponding metal fitting-side elastic deformation portion 55 to face outward (the left-side metal fitting-side elastic deformation portion 55 is the left side, and the right-side metal fitting-side elastic deformation portion 55 is Right side) elastic deformation. As a result, the metal fitting side elastic deformation portion 55 on the left side and the metal fitting side elastic deformation portion 55 on the right side are sandwiched between the left and right sides of the plug connector 15 while being elastically pressed in the direction in which they approach each other. Therefore, the elastic pressure generated by the left and right metal fitting side elastic deformation portions 55 at this time does not form an elastic pressure in a direction in which the plug connector 15 is disengaged from the receptacle connector 35. Therefore, as long as the plug connector 15 is not intended to be relatively moved upward relative to the receptacle connector 35, the fully connected state of the plug connector 15 and the receptacle connector 35 is maintained.

As shown in the above description, the connector 10 of the present embodiment is easy to maintain the plug connection. When the connector 15 is connected to the receptacle connector 35, and the plug connector 15 is connected to the receptacle connector 35, the operator can easily feel the click feeling (it is clearly recognized that the receptacle connector 35 and the plug connector 15 have been phased together connection).

Then, in the fitting operation of the plug connector 15 and the socket connector 35, or after the fitting, the conduction sensing circuit senses that the conduction sensing pattern of the circuit substrate 34 is electrically connected to the conduction sensing pattern of the circuit substrate 70, The operator can recognize that the plug connector 15 is properly fitted with the receptacle connector 35 (the plug contact 25 is in formal contact with the receptacle contact 60). On the other hand, when the conduction sensing circuit senses the non-conduction state during or after the fitting operation of the plug connector 15 and the receptacle connector 35, it can be recognized that the plug connector 15 and the receptacle connector 35 are incomplete. The fitting state (the plug contact 25 is not in contact with the socket contact 60, or the first plug side protrusion 26b1 is intended to pass over the middle of the first socket side protrusion 64a, or the second plug side protrusion 26a1 is intended to pass over the second socket side An unstable contact state like the middle of the projection 66a).

In addition, the metal fitting-side elastic deformation portion 55 of the socket-side fixing metal fitting 50 is separated from the surface of the housing groove 45c of the outer peripheral wall 42 (the surface on the inner peripheral side of the outer peripheral wall 42) toward the inner peripheral side. Elastically deformed in the front and rear direction. Therefore, when the socket connector 35 is connected to the plug connector 15, the two are separated, and when the socket connector 35 is connected to the plug connector 15 again, the socket side fixing metal fitting 50 and the plug side can be fixed. The metal fitting 28 is firmly fastened.

Further, when the plug connector 15 is connected to the receptacle connector 35, the first plug side protrusion 26b1 and the second plug side protrusion 26a1 pass the first socket side protrusion 64a and the second socket side with a (slightly) time difference, respectively. Protrusion 66a. Therefore, the first plug side protrusion 26b1 and the second plug side protrusion 26a1 (completely) simultaneously pass over the first socket side protrusion 64a and the second socket side protrusion 66a. In comparison, the force required to connect the plug connector 15 to the receptacle connector 35 can be reduced.

In addition, by engaging the recess 19 and the engaging projection 43, after the plug connector 15 and the receptacle connector 35 are relatively moved only in the up and down direction (regular rotation), the plug contact 25 is brought into contact with the socket. The contact of the sub-60 and the contact of the plug-side fixing metal fitting 28 with the socket-side fixing metal fitting 50. Therefore, before the plug contact 25 comes into contact with the socket contact 60, the plug-side fixing metal fitting 28 can be surely prevented from coming into contact with the socket-side fixing metal fitting 50.

Further, the planar shape of the socket-side fixing metal fitting 50 of the receptacle connector 35 is substantially Since the shape of the socket is large, the fixing strength of the socket-side fixing metal fitting 50 to the socket insulator 40 is large as compared with the shape of the straight line (for example, a shape having only a portion corresponding to the short-side fixing portion 51 and the short-side fastening piece 53). Further, the plug connector 15 includes a guide inclined surface 18a and a guide inclined surface 18b, and the receptacle connector 35 includes a contact convex portion 42a1, an inclined surface 42a2, a rounded surface 43a, and an inclined guide surface 43b. Therefore, in the case where the connector 10 (the receptacle connector 35) is miniaturized, the plug connector 15 and the receptacle connector 35 can be removed while reducing the gap in which the socket-side fixing metal fitting 50 is peeled off by the socket insulator 40. The insertion is smoothly fitted by various angles (under a plan view).

Further, the plug-side fixing metal fitting 28 is provided in the plug connector 15 such that the plug-side fixing metal fitting 28 contacts the socket-side fixing metal fitting 50 of the receptacle connector 35, and thus the plug-side fixing metal fitting 28 is omitted from the plug connector 15. When the plug insulating member 16 is brought into contact with the socket-side fixing metal fitting 50, the plug connector 15 (the plug insulating member 16) is less damaged or deformed by the contact with the socket-side fixing metal fitting 50.

Further, when the contact portion 30 of the plug-side fixing metal fitting 28 comes into contact with the metal fitting-side elastic deformation portion 55 of the socket-side fixing metal fitting 50, the metal fitting-side elastic deformation portion 55 is elastically deformed. Therefore, even if the plug connector 15 is slightly moved in the receptacle connector 35, the contact state of the contact portion 30 with the metal fitting side elastic deformation portion 55 is maintained.

The present invention has been described above based on the above embodiments, but the present invention is not limited to the above embodiments, and can be implemented while performing various modifications.

For example, the vertical position of the first plug-side protrusion 26b1 and the second plug-side protrusion 26a1 may be the same, or the upper and lower positions of the first socket-side protrusion 64a and the second socket-side protrusion 66a may be the same.

Further, one or more plug side protrusions may be provided in one plug contact 25, and one or more socket side protrusions may be provided in one socket contact 60. However, in the case of three or more cases, when the plug connector and the socket connector are connected, the plug-side fixing metal fitting 28 contacts the socket-side fixing metal after all the plug-side projections are protruded downward over all the socket-side projections. The metal fitting side elastic deformation portion 55 of the fitting 50.

A circuit board in which one of the plug connector 15 and the receptacle connector 35 is relatively opposed to each other may be connected in a so-called right angle (RA) state.

Further, the plug-side fixing metal fitting 28 and the socket-side fixing metal fitting 50 may be connected to a power supply circuit connected to a power source (not shown).

Further, a circuit board other than the rigid substrate (for example, an FPC (Flexible Printed Circuit Board)) may be connected to the plug connector 15 or the receptacle connector 35.
