[Summary of the invention] [Problems to be solved by the invention]

Patent Document 1 states that during the unlocking operation, the unlocking operation portion positioned on the side of the locked position than the elastic deformation member described above receives the unlocking operation force (pressing force) toward the unlocking position in the longitudinal direction. . The above-mentioned locking fitting is formed as a whole which is longer in the above-mentioned longitudinal direction. Therefore, the elastic pushing force of the elastic deformation member and the locking release operating force against the elastic pushing force are used to make the locking fitting bear the compressive force in its longitudinal direction. The direction at right angles to the longitudinal direction (for example, the plate thickness direction of the locking fitting) is likely to be bent and deformed due to buckling. When the above-mentioned bending deformation occurs, the locking fitting cannot smoothly move to the unlocking position, and the locking state of the locking part and the locked part of the counterpart connector may not be released. In addition, with respect to the static force of the elastic thrust being constant, the unlocking operation force is larger than this force, and it is mostly applied with impact, so there is a risk of high bending deformation. In addition, the bending deformation of the above-mentioned locking fitting may also cause damage to the main body of the locking fitting. In addition, in order to prevent bending deformation, the size of the locking fitting is increased in the direction at right angles to the longitudinal direction. In order to ensure the strength of the locking fitting body, the size of the connector will increase the size of the connector.

In view of the above situation, the present invention provides an electrical connector that can smoothly move the locking member to the unlocking position during the unlocking operation without increasing the size of the locking fitting. [Means used to solve the problem]

The electrical connector related to the present invention is an electrical connector that is pluggably fitted and connected to a counterpart connector, and has: a housing extending in a direction at right angles to the connector plugging and unplugging direction as the longitudinal direction; The longitudinal direction is the terminal arrangement direction and is aligned and held in the housing; the locking member is arranged in the housing portion of the housing, and is located at a locking position that can prevent the mating connector from being pulled out and that allows the mating connector Between the pulled out locking release positions, it can move along the terminal arrangement direction; and the elastic pushing part elastically pushes the locking member toward the locking position.

In a related electrical connector, the present invention is based on the above-mentioned locking member, which has a locking protrusion formed by extending along the terminal arrangement direction, protruding toward the locking position side in the terminal arrangement direction, and a locking release operation part, When the terminal arrangement direction is on the unlocking position side of the elastic pushing portion, and the locking member receives the elastic pushing force from the elastic pushing portion and is located at the locking position, the locking protrusion is locked to the counterpart provided on the opposite side. The locked portion of the connector can prevent the counterpart's connector from being pulled out, and the unlocking operation portion can allow the counterparty to move toward the unlocking position when the unlocking operation portion receives the operating force against the elastic thrust and moves the locking member toward the unlocking position. It is characterized by the unplugging of the connector.

In the present invention, during the locking operation, the unlocking operation portion on the unlocking position side than the above-mentioned elastic push portion receives the unlocking operation force toward the unlocking position. At this time, the locking member is subjected to a tensile force in the terminal arrangement direction by the elastic thrust from the elastic pushing part and the locking release operating force against the elastic thrust, and therefore bends and deforms in a direction at right angles to the terminal arrangement direction. Difficulties arise. As a result, the locking fitting is smoothly moved to the unlocking position, and the locked state of the locking portion and the locked portion of the counterpart connector can be surely released.

In the present invention, the unlocking operation portion may be positioned on the unlocking position side of the elastic pushing portion and the locking protrusion in the terminal arrangement direction.

In the present invention, the housing may have a locking position side restricting portion that abuts against a part of the locking member and restricts movement of the locking member toward the locked position side. As described above, by providing the locking position side restricting portion on the housing, the locking member receiving the elastic thrust from the elastic pushing portion can be maintained at the predetermined locking position.

In the present invention, the housing may have a lock release position side restricting portion that abuts against a part of the lock member and restricts movement of the lock member to the unlock position side. As described above, by providing the unlocking position side restricting portion on the housing, the locking member that receives the unlocking operation force can be maintained at the predetermined unlocking position.

In the present invention, the electrical connector may have a shell member attached to the housing, and the spring push portion and the shell member may be integrally formed. As in the case where the shell member is provided, the elastic pushing portion and the shell member are formed integrally, thereby reducing the number of parts and reducing the manufacturing cost compared with the case where the shell member is provided with the elastic pushing portion as a separate member. In addition, when the connector is manufactured, the spring-pushing portion can also be installed at the same time by installing the shell member of the housing. Therefore, the step of installing the spring-pushing portion to the housing can be omitted, and the manufacturing of the connector is changed. It has to be simple. [Effects of the invention]

According to the present invention, as described above, during the unlocking operation, the unlocking operation portion on the unlocking position side than the above-mentioned elastic pusher receives the operating force toward the unlocking position, so that the locking member is placed on the terminal The arrangement direction acts as a tensile force, making it difficult to generate bending deformation due to buckling in the direction at right angles to the terminal arrangement direction. As a result, the locking fitting is smoothly moved to the unlocking position, and the locked state of the locking portion and the locked portion of the counterpart connector can be surely released. In addition, it is possible to prevent the locking member body from being damaged due to bending deformation of the locking member. In addition, there is no need to increase the size of the locking fitting at a right angle with respect to the terminal arrangement direction to ensure the strength of the locking fitting body in order to prevent bending deformation, so that the size of the connector can be avoided.

The annular space opened upward between the protruding wall 12 and the peripheral wall 13 forms a receiving portion 16 for receiving the peripheral wall 53 as a fitting portion of the plug connector 2.

Although the socket-side housing 10 has a form that holds the socket terminals 20, the locking fittings 30, and the shell member 40, to understand the form, the socket-side housing 10 will be further explained. First, the socket terminals 20, the locking fittings 30 and The shell member 40 is illustrated.

The plurality of socket terminals 20 have socket signal terminals 20S and socket power terminals 20P. As shown in Figures 1 and 2, the two rows of terminal rows are composed of a plurality of socket signal terminals 20S arranged at equal intervals, and are arranged in the same row as the socket signal terminals 20S on both sides of the arrangement range of the socket signal terminals 20S. A socket power terminal 20P is formed.

The plug power terminal 60P has the same basic structure as the plug signal terminal 60S, and is formed in the same shape as the plug signal terminal 60S in the terminal arrangement direction. As shown in Figures 1 and 2, in the plug power terminal 60P, the part corresponding to the plug signal terminal 60S is represented by the symbol "P" instead of "S". The plug power terminal 60P has a larger dimension in the terminal width direction (terminal arrangement direction) than the plug signal terminal 60S in that it is different from the plug signal terminal 60S. The locking section 62B-1P is formed to have the same height as the locking section 62B-1S of the plug signal terminal 60S.

As shown in FIG. 1 and FIG. 2, the locked fitting 70 is arranged on both sides of the end groove portion 55A in the connector width direction, and is held on the end wall 55 by integral molding. The locked fittings 70 are formed in a mutually symmetrical shape in the width direction of the connector, and formed by bending a metal plate member in the thickness direction. Each of the locked fittings 70 is as shown in Figure 2 and has: a base 71 extending along the bottom surface of the plug-side housing 50 (see Figure 1); upwards from the end of the base 71 inward in the connector width direction A raised portion 72 raised from the upper part of the raised portion 72 in the width direction of the connector, that is, a protruding portion 70A protruding toward the end groove portion 55A from the upper portion of the raised portion 72 (below in the first figure); and from the base 71 The outer end of the connector in the width direction of the connector rises upward and is a side plate portion 76 that faces the raised portion 72 in the connector width direction. The locked fitting 70 is displayed from the terminal arrangement direction by the base 71, the upright portion 72, and the side plate portion 76, and forms a substantially U-shape.

The base portion 71 has a connecting portion 71A extending outward in the terminal arrangement direction and the connector width direction. The connecting portion 71A is a corresponding circuit portion (not shown) that extends outside the plug-side housing 50 and is soldered to the mounting surface of the circuit board B2 as shown in FIGS. 1 and 2. Moreover, in this embodiment, as shown in Figure 1, the bottom surface (on the top of Figure 1) of the base 71 is exposed from the bottom of the plug-side housing 50 across its entire area, so the base 71 is outside the connecting portion 71A. The part is also soldered to the corresponding part of the mounting surface.

The protrusion 70A protrudes from the inner wall surface 55A-1 (a surface at right angles to the connector width direction) of the end groove portion 55A in a state of holding the locked fitting 70 on the end wall 55 of the plug-side housing 50 It is positioned in the end groove portion 55A. The end located on the inner side of the terminal arrangement direction of the protrusion 70A is formed as the inner locked portion 73, and the end located on the outer side of the terminal arrangement direction of the protrusion 70A is formed as the outer locked portion 74.

In addition, the side plate portion 76 is a plate surface that is exposed from the side surface (a surface at right angles to the connector width direction) of the end wall 55 of the plug-side housing 50 and protects the side surface of the end wall 55. In addition, the side plate portion 76 is in the connector fitting state, and the plate surface exposed from the side surface of the end wall 55 is in contact with the contact piece 47 of the housing member 40 of the receptacle connector 1 to form electrical conduction.

As shown in Fig. 5(A), in this embodiment, the outer locked part 74 of the locked fitting 70 located at the front (on the right in Fig. 5(A)) is locked with the front of the locking fitting 30 The tightening protrusion 33A is locked, and the inner locked portion 73 of the locked fitting 70 located rearward (on the left in FIG. 5(A)) is locked with the rear locking projection 33B of the locking fitting 30. Therefore, in the present embodiment, the inner locked portion 73 of the locked fitting 70 located at the front and the outer locked portion 74 of the locked fitting 70 located at the rear are not used. And, as already explained, the locking fitting 30 can be set in the posture shown in Fig. 4 in which the posture is reversed left and right. At this time, the inner locked part 73 of the locked fitting 70 located in the front and the being located in the rear The outer locked portion 74 of the locking fitting 70 can be used as a locked portion.

Next, the connector fitting operation of the receptacle connector 1 and the plug connector 2 will be described based on the first, second, fifth, and sixth figures. First, the socket connector 1 and the plug connector 2 are mounted on the corresponding circuit boards B1 and B2 by soldering connection. Next, as shown in Figure 1, the receptacle connector 1 is formed with the receiving portion 16 upward, and above the receptacle connector 1, the plug connector 2 is formed with the receiving portion 56 (see Figure 2) downward. Posture.

Next, maintain the posture of Figure 1 and lower the plug connector 2 so that the protruding wall 12 of the receptacle connector 1 enters the receiving portion 56 of the plug connector 2 from below, and the surrounding wall of the plug connector 2 53 enters into the receiving portion 16 of the socket connector 1 from above. As a result, the contact leg 62A of the plug terminal 60 of the plug connector 2 is brought into contact pressure contact with the contact portion 22A of the receptacle terminal 20 of the receptacle connector 1. In addition, the side plate portion 76 of the locked fitting 70 of the plug connector 2 is brought into contact with the contact piece 47 of the shell member 40 of the corresponding receptacle connector 1 with contact pressure.

In addition, during the connector fitting process, the locked portions 74, 73 of the two locked fittings 70 provided in the plug connector 2 respectively abut against the locking protrusions of the locking fitting 30 at the locked position. The upper edges (inclined edges) of the portions 33A, 33B press the locking protrusions 33A, 33B in the terminal arrangement direction with a pressing force toward the front (on the right in Figure 5(A), (B)). When the locking protrusions 33A and 33B receive the above-mentioned pushing force, the locking fitting 30 moves forward to the unlocking position (see Fig. 6(A), (B)). At this time, the movement of the locking fitting 30 is allowed by the elastic deformation (compression) of the elastic pushing portion 45 pushed by the elastic pushing portion 35 toward the locking fitting 30.

As described above, the locking fitting 30 comes to the unlocking position, thereby allowing the plug connector 2 to further descend. And, as shown in Fig. 5(A), the front (on the right in Fig. 6(A)) of the locked fitting 70 is outside the locked portion 74 and behind (on the left in Fig. 5(A)) Once the inner locked portion 73 of the locked fitting 70 reaches a position lower than the locking protrusions 33A, 33B of the locking fitting 30, the locking protrusions 33A, 33B are released from the aforementioned pressing force. As a result, the elastic pushing portion 45 reduces the amount of elastic deformation and returns to the rear, and returns to the original locked position. The locking protrusions 33A, 33B that return to the locked position are shown in Figure 5(A), located above the corresponding locked portions 74, 73, and can be locked with respect to the locked portions 74, 73 The position is locked in the direction (upward) where the connector is pulled out. As described above, the terminals 20 and 60 are connected to each other, and the contact piece 47 and the side plate portion 76 are connected to each other, and the locking fittings 30 and 70 are locked to each other, thereby completing the connector fitting action.

Next, referring to Figures 6 (A) and (B), the connector pull-out operation will be described. When pulling out the plug connector 2 in the mated state with the connector of the socket connector 1, as shown in Fig. 6(B), insert the tool P into the lock of the locking fitting 30 of the socket connector 1 from above The unlocking operation is performed between the unlocking operation portion 36 and the outer end plate portion 44 of the shell member 40. The tool P has a plate-shaped portion whose front and rear direction is the plate thickness direction, and the plate thickness dimension is formed to be larger than the distance between the unlocking operation portion 36 and the outer end plate portion 44. Therefore, when the tool P is inserted from above, when the unlocking operation portion 36 receives the pressing force as the unlocking operation force from the tool P forward, the elastic pieces 45A, 45B of the elastic pushing portion 45 of the shell member 40 It is pressed toward the elastically pushed portion 35 of the locking fitting 30 to be elastically deformed forward. In this way, the locking fitting 30 resists the elastic thrust from the shell member 40 to the rear and moves forward to reach the unlocked position. At this time, the longitudinal portions 34A-2, 34B-2 of the supported portions 34A, 34B of the lock fitting 30 abut against the lock release position side restricting portions 12B-3, 12A-2 of the socket-side housing 10 from the rear, respectively Therefore, the forward movement of the locking fitting 30 is restricted, and the locking fitting is surely maintained at the unlocked position.

When the locking fitting 30 comes to the unlocking position, as shown in Figures 6(A) and (B), the locking projections 33A, 33B and the locked fitting 70 of the plug connector 2 are unlocked The parts 74 and 73 can be locked in a locked state. In addition, the plug connector 2 is lifted toward the connector pull-out direction (upward), so that the plug connector 2 can be easily pulled out, and the connector pull-out operation is completed.

In this embodiment, the lock fitting 30 is the unlocking operation portion 36 located forward (on the side of the unlocking position) than the elastic pushing portion 45. Therefore, during the unlocking operation, the locking fitting 30 is driven from the elastic The elastic thrust (rearward force) of the push portion 45 and the unlocking operation force (forward force) against the elastic thrust bear the tensile force in the front and rear directions, so in the direction at right angles to the front and rear directions (up and down) It is difficult to produce bending deformation in the direction and the width direction of the connector. As a result, the locking fitting 30 is smoothly moved to the unlocking position, and the locked state of the locking protrusions 33A, 33B and the locked portions 74, 73 of the plug connector 2 can be surely released. In addition, the bending and deformation of the locking fitting 30 can prevent the body of the locking fitting 30 from being damaged. In addition, there is no need to increase the size of the locking fitting 30 in a direction at right angles to the terminal arrangement direction in order to prevent bending deformation to ensure the strength of the locking fitting 30 body, thus avoiding the enlargement of the connector.

Although the present embodiment uses a tool to perform the above-mentioned unlocking operation, the use of a tool is not necessary. For example, the unlocking operation portion 36 may be picked up by fingers and pulled forward to perform the unlocking operation with fingers.

Although this embodiment uses the locking fitting 30 of a metal member as the locking member, for example, a material such as resin may be formed into a locking member instead of this.
