Description

The disclosure of this application relates to a right angle connector.

A right angle connector is known as a kind of electric connector. The right-angle connector refers to a connector in which the substrate surface of the substrate on which the right-angle connector is mounted intersects with the fitting portion (fitting surface) of the object to be connected provided on the right-angle connector. Here, the "fitting portion" of the right-angle connector means the fitting port of the housing of the right-angle connector into which the object to be connected is inserted, the insertion portion of the housing of the right-angle connector inserted into the object to be connected, or the connection. Includes terminals that are inserted into the object. In the right-angle connector, for example, the board surface of the first board on which the right-angle connector is mounted and the board surface of the second board on which the mating connector as a connection object is mounted extend each board surface. In some cases they are arranged so that they intersect each other. As an example of the conventional right angle connector, for example, the one described in JP-A-2011-76755 (Patent Document 1) is known.

The right angle connector (floating connector 100) described in Japanese Patent Application Laid-Open No. 2011-76755 is displaceable with respect to a fixed housing (fixed housing 200) held on a first substrate (circuit board 101) and a fixed housing. It includes a movable housing (floating housing 300) and terminals (plug terminals 102). The terminal has a fitting portion (contact portion 106) and a movable portion (109). The fitting portion is inserted into the object to be connected (socket connector 400, contact portion 407). The movable portion is made of an elastically deformable metal spring piece and supports the movable housing in a displaceable manner with respect to the fixed housing. Therefore, when the right angle connector and the object to be connected are fitted to each other, even if they are displaced from each other in the crossing direction with respect to the fitting direction, the movable portion is elastically deformed and the movable housing moves. , It is possible to fit while absorbing mutual misalignment.

JP 2011-76755, FIGS. 1, 2

By the way, in the conventional right angle connector, when it receives vibration or impact in the mating direction with the connection object and the removal direction which is the opposite direction, the contact portion between the terminal and the connection object may cause contact sliding. There is. When this contact sliding occurs repeatedly, the plating for lowering the electric resistance value is peeled off, the electric resistance value is increased, and the connection reliability as an electric connector is lowered.

An object of the present application is to make it possible to maintain connection reliability even if a right angle connector having a floating function and an object to be connected are subjected to vibration in an installation environment.

The embodiments disclosed in this application to achieve the above object can have the following features.

A first embodiment of the present application comprises a right angle connector arranged on a substrate surface of a first substrate and a connection object to be fitted with the right angle connector, and the right angle connector and the connection are provided. The mating direction and the removing direction with the object intersect with the height direction of the right angle connector with respect to the substrate surface, and the right angle connector is with the first housing arranged on the first substrate. A second housing that fits into the connection object, a contact portion that makes conductive contact with the connection object, and a movable portion that supports the second housing in a displaceable manner with respect to the first housing. The second housing and the object to be connected are fitted to each other in the mating direction to form an initial mating state with the right angle connector and the object to be connected. Regarding the structure, the movable portion has an elastic force for elastically deforming in the fitting direction and the removing direction, and the contact portion and the connecting object in a state where the connecting object is fitted in the second housing. It is formed to be smaller than the holding force in the fitting direction and the removing direction with the object, and the second housing is formed between the second housing and the connecting object in the initial fitting state. It is characterized by having a fitting gap for fitting the housing and the connection object at a fitting position deeper than the fitting position in the initial fitting state.

According to the present embodiment, the movable portion has the elastic force for elastically deforming in the fitting direction and the removing direction, and the contact portion in a state where the connection object is fitted in the second housing. It is formed to be smaller than the holding force in the fitting direction and the removing direction between the object and the object to be connected. Therefore, even if the fitted right-angle connector and the object to be connected are subjected to vibration and impact, the contact sliding between the contact portion and the object to be connected can be suppressed. Further, between the second housing and the connection object in the initial fitting state, the second housing and the connection object are further placed at a fitting position in the initial fitting state. It has a fitting gap for fitting at a deep fitting position. Therefore, even if a force that brings the right angle connector and the connection object closer to each other acts in the installation environment of the right angle connector and the connection object in the initial fitting state of the right angle connector and the connection object, the initial fitting The fitting position between the second housing and the object to be connected can be made deeper beyond the fitting position in the state, and the force can be absorbed. When the second housing is displaced with respect to the first housing after the fitting position is deepened, the contact portion of the terminal and the object to be connected are held without sliding in contact with each other as described above. Since the contact position is maintained by the force, it is possible to suppress a decrease in connection reliability due to plating peeling of the contact portion.

The fitting structure has a contact receiving portion that abuts and stops the second housing that is pushed and moved by the connection object when the second housing and the connection object are fitted. The initial fitting state can be configured to be formed by fitting the connection object into the second housing that has come into contact with the contact receiving portion and stopped.

According to this fitting structure, since the second housing is fitted to the connection object in a state where it is in contact with the contact receiving portion and stopped, it is easy to connect the connection object to the stopped second housing. Can be fitted to.

The contact receiving portion can be configured to be a wall of the first housing formed in the height direction.

Since the abutting receiving portion is the wall of the first housing, the abutting receiving portion can be provided without increasing the number of parts constituting the fitting structure. Further, since the contact receiving portion is the wall of the first housing, the fitting position in the initial fitting state can be determined in the positional relationship with the first housing, that is, within the range of the assembly intersection of the right angle connector. ..

The contact receiving portion can be configured to be a receiving member provided on the first substrate or the first housing.

Since the abutting receiving portion is a receiving member provided on the first substrate or the first housing, a function suitable for receiving the second housing independent of the material and structure of the first substrate and the first housing. And can be a receiving member having features. As an example, such a receiving member can be composed of a metal piece. For example, the metal piece can be configured as a metal piece fixed to the first substrate. Further, the receiving member can be configured as a metal piece fixed to the first housing. Further, the receiving member can be configured as a metal piece for fixing the first housing to the first substrate.

The connection object can be configured to be a mating connector or an electric element.

Since the object to be connected is a mating connector or an electric element, various fitting structures using a right angle connector can be realized.

A second embodiment of the present application is a fitting method in which a right angle connector arranged on a substrate surface of a first substrate and an object to be connected are fitted, and the right angle connector is the first substrate. A first housing arranged in, a second housing displaceable with respect to the first housing, a contact portion that makes conductive contact with the connection object, and the first housing and the second housing. It is provided with a terminal having a movable portion that supports the right angle connector so as to be relatively displaceable, and the fitting direction and the removing direction of the right angle connector and the connection object are the height direction of the right angle connector with respect to the substrate surface. The right-angle connector and the connection object are the right-angle connector and the connection object in which the connection object and the right-angle connector are brought close to each other in the fitting direction. With respect to the fitting method with, the movable portion has an elastic force for elastically deforming in the fitting direction and the removing direction, and the contact portion in a state where the connection object is fitted in the second housing. It is formed so as to be smaller than the holding force in the fitting direction and the removing direction between the connector and the object to be connected, and the second housing stays in the second housing until the movement of the second housing is stopped. When the right angle connector and the connection object come close to each other after the first process of fitting the connection object and the first process, the second housing and the connection object after the first process After the second process in which the fitting position between the second housing and the connection object becomes deeper than the fitting position with the object, and the contact portion and the connection object after the second process. By moving at least one of the first housing and the second housing in a direction away from the other while maintaining the contact position, the movable portion fits the second housing at least. It is characterized by having a third process of forming a fitting state that supports displaceably in the mating direction and the pulling out direction.

In the first step, the object to be connected is fitted into the second housing.

In the second process, the right angle connector and the connection object come closer to each other after the first process, so that the second housing is closer to the connection object than the fitting position between the second housing and the connection object after the first process. And the mating position with the object to be connected becomes deeper. Therefore, after the first process, in the installation environment of the right angle connector and the object to be connected, a force that brings the right angle connector and the object to be connected close to each other (for example, vibration (including resonance vibration), impact, etc.) is generated in the installation environment. Even if an external force (possible external force) acts, the fitting position after the first process is exceeded, and the second housing and the object to be connected are further fitted beyond the fitting position after the first process. By doing so, the force can be absorbed.

In the third process, at least one of the first housing and the second housing moves in a direction away from the other while maintaining the contact position between the contact portion and the object to be connected after the second process. By doing so, the movable portion forms a fitting state in which the movable portion supports the second housing in a displaceable manner at least in the fitting direction and the removing direction. Here, specifically, there are three patterns of movement of the first housing and the second housing in the separation direction for forming the fitted state. The first is the case where the first housing moves away from the second housing. The second is the case where the second housing moves away from the first housing. The third is the case where both the first housing and the second housing move in directions away from each other. Then, at the contact position between the contact portion formed by the second process and the connection object, the elastic force of the movable portion for elastically deforming in the fitting direction and the removal direction is between the contact portion and the connection object. It is maintained because it is formed to be smaller than the holding force in the fitting direction and the pulling direction. Therefore, the contact position between the contact portion and the object to be connected after the third process is the same as the contact position formed by the second process, and contact sliding does not occur. Further, when at least one of the first housing and the second housing moves away from the other, the movable portion supports the second housing in a displaceable manner at least in the fitting direction and the removing direction. Therefore, even if the second housing that is fitted with the object to be connected is vibrated or impacted in the installation environment, the second housing is relative to the first housing in the fitting direction and the removing direction. Can be displaced. At this time as well, the occurrence of contact sliding at the contact portion between the contact portion of the terminal and the object to be connected is suppressed, and the contact position is maintained by the holding force, so that the connection reliability is lowered due to the plating peeling of the contact portion. It can be suppressed.

According to the disclosure of the present application, the connection reliability of the right angle connector having a floating function can be maintained.

1st Embodiment [FIGS. 1 to 12]

The fitting structure 1 of the first embodiment mounts the right angle connector 10, the mating connector 40, the first substrate P10 on which the right angle connector 10 is mounted, the first support member P11, and the mating connector 40. A second substrate P20 and a second support member P21 are included.

Right angle connector 10

The right angle connector 10 includes a fixed housing 11 as a "first housing", a movable housing 12 as a "second housing", and terminals 13.

Fixed housing 11
The fixed housing 11 is made of a resin molded body. The fixed housing 11 has an upper wall 11a, a pair of left and right side walls 11b, and a rear wall 11c, and has no walls on the front and bottom surfaces and an opening is formed. Since the fixed housing 11 does not have a bottom wall facing the first substrate P10, the height is lowered by that amount, and therefore the right angle connector 10 is miniaturized. A storage space 11d is formed inside the fixed housing 11. A part of the movable housing 12 and a part of the terminal 13 are arranged in the accommodation space 11d. On the inner surface of the rear wall 11c forming the accommodation space 11d, a plurality of fixed housing terminal fixing grooves 11e for fixing the terminals 13 described later to the fixed housing 11 are formed in parallel in the terminal arrangement direction X. Further, a plurality of contact receiving portions 11f are formed on the inner surface of the rear wall 11c of the fixed housing 11. The abutting receiving portion 11f is formed as a wall surface extending from the inner surfaces of the left and right side walls 11b along the terminal arrangement direction X.

Fixing portions 11g for fixing the fixing bracket 14 are formed on the left and right side walls 11b of the fixing housing 11, respectively. The fixing portion 11g for each fixing bracket is formed as a groove having a depth in the height direction Z of the fixing housing 11 from the bottom surface of the side wall 11b. The fixing metal fitting 14 is fixed to the fixing metal fitting fixing portion 11g by press fitting.

Movable housing 12
The movable housing 12 is formed of a resin molded body. The movable housing 12 is formed in a box shape having an upper wall 12a, left and right side walls 12b, a rear wall 12c, and a bottom wall 12d. A fitting port 12e as a "fitting portion" into which the mating connector 40 is inserted is formed on the front surface of the movable housing 12. The right angle connector 10 has an arrangement relationship in which the opening edge on the tip end side of the fitting port 12e and the substrate surface P10a of the first substrate P10 intersect. A fitting chamber 12f for fitting and connecting with the mating connector 40 is formed inside the movable housing 12 (in the back of the fitting port 12e) (FIG. 8). The fitting chamber 12f is composed of the inner surface of the movable housing 12. On the inner surface of the upper wall 12a and the inner surface of the bottom wall 12d forming the fitting chamber 12f, a contact portion 13e described later of the terminal 13 (first terminal 13A, second terminal 13B) and a fixing portion 13d for the movable housing are formed. A plurality of terminal accommodating grooves 12g for holding the above are formed. The terminal accommodating groove 12g is composed of a plurality of first terminal accommodating grooves 12g1 on the upper wall 12a and a plurality of second terminal accommodating grooves 12g2 on the bottom wall 12d. The first terminal accommodating groove 12g1 and the second terminal accommodating groove 12g2 are formed so as to be alternately displaced in the terminal arrangement direction X. Therefore, the first terminal 13A and the second terminal 13B are also arranged so as to be alternately displaced in the terminal arrangement direction X. The terminal accommodating grooves 12g are formed as grooves having a depth in the height direction Z of the movable housing 12. The rear end portion of the terminal accommodating groove 12g is formed so as to penetrate the rear wall 12c in the front-rear direction Y. The contact portion 13e of the terminal 13 and the fixed portion 13d for the movable housing are inserted and held from the rear end portion of the terminal accommodating groove 12g that opens in the rear wall 12c.

The movable housing 12 has a plurality of first displacement regulating protrusions 12h. The first displacement regulating projection 12h on the left side protrudes to the left of the left side wall 12b and protrudes behind the rear wall 12c, and has a vertical wall shape having the same height as the side wall 12b and the rear wall 12c of the movable housing 12. It is formed. The first displacement regulating projection 12h on the right side projects to the right of the side wall 12b on the right side, projects rearward of the rear wall 12c, and has a vertical wall shape having the same height as the side wall 12b and the rear wall 12c of the movable housing 12. It is formed.

The first displacement regulating projection 12h has a rear contact surface 12h1. The rear contact surface 12h1 is formed as a flat surface, and is positioned so as to face the contact receiving portion 11f, which is also a flat surface. The rear contact surface 12h1 is formed as a "fixed housing contact portion (first housing contact portion)" facing the rear wall 11c of the fixed housing 11. For example, when the movable housing 12 is displaced toward the rear wall 11c of the fixed housing 11, the rear contact surface 12h1 comes into contact with the contact receiving portion 11f, and the displacement of the movable housing 12 is stopped. The first displacement regulating projection 12h including the rear contact surface 12h1 functions as a stopper portion that regulates excessive rearward displacement of the movable housing 12. Further, the rear contact surface 12h1 is formed as a rectangular surface having a height corresponding to the height of the movable housing 12 excluding the second displacement regulating projection 12i described later. Therefore, the movable housing 12 can be in plane contact with the contact receiving portion 11f over the height direction Z. When the mating connector 40 is fitted into the movable housing 12, as will be described later, the movable housing 12 is pushed by the mating connector 40 to move, and the rear contact surface 12h1 comes into contact with the contact receiving portion 11f. At this time, the rear contact surface 12h1 and the contact receiving portion 11f are in flat contact with each other, so that the movable housing 12 can be corrected to a posture without inclination. As a result, the mating connector 40 can be inserted horizontally and straight into the movable housing 12, and the fitting operation can be easily performed.

Further, the side surface of each of the first displacement regulating protrusions 12h is formed as a side contact surface 12h2. The side contact surface 12h2 is formed as a flat surface, and is located so as to face the inner side surface 11b1 of the side wall 11b of the fixed housing 11 which is also a flat surface. When the movable housing 12 is displaced in the left-right direction X, the side contact surface 12h2 comes into contact with the inner side surface 11b1 to stop the excessive displacement of the movable housing 12. Further, the side contact surface 12h2 is formed as a rectangular surface having a height corresponding to the height of the movable housing 12 excluding the second displacement regulating projection 12i described later. Therefore, the movable housing 12 can be in plane contact with the inner side surface 11b1 over the height direction Z. Therefore, even if the movable housing 12 is displaced in the left-right direction X in an inclined posture and comes into contact with the inner side surface 11b1, the side contact surface 12h2 and the inner side surface 11b1 are in flat contact with each other, so that the movable housing 12 is tilted. Can be corrected to no posture.

Further, the front surface (front surface) of each first displacement regulating projection 12h is formed as a front contact surface 12h3. The front contact surface 12h3 is formed as a flat surface, and is located so as to face the inner front surface 11b2 of the side wall 11b of the fixed housing 11, which is also a flat surface. When the movable housing 12 is displaced forward (withdrawal direction) in the front-rear direction Y, the front contact surface 12h3 comes into contact with the inner front surface 11b2, and excessive displacement of the movable housing 12 to the front Y can be stopped. Further, the front contact surface 12h3 is formed as a rectangular surface having a height corresponding to the height of the movable housing 12 excluding the second displacement regulating projection 12i described later. Therefore, the movable housing 12 can be in plane contact with the inner front surface 11b2 over the height direction Z. Therefore, even if the movable housing 12 is displaced forward in an inclined posture and comes into contact with the inner front surface 11b2, the front contact surface 12h3 and the inner front surface 11b2 are in flat contact with each other, so that the movable housing 12 is in a non-tilted posture. Can be corrected to.

As described above, the locking recess 11h (inner side surface 11b1, inner front surface 11b2, contact receiving portion 11f) is formed inside the fixed housing 11. Inside the locking recess 11h, the first displacement regulating projection 12h of the movable housing 12 is arranged so as to face each other via the movable gap G. When the movable housing 12 is displaced, the first displacement regulating projection 12h is displaced with the range of the movable gap G as the movable limit. Then, when the first displacement regulating projection 12h comes into contact with the locking recess 11h, it is possible to prevent the movable housing 12 from being excessively displaced in the left-right direction X and the front-rear direction Y. Further, the movable housing 12 can be displaced in the upward and downward directions in the height direction Z. When the movable housing 12 is displaced upward, the upper wall 12a can be in contact with the inner surface of the upper wall 11a of the fixed housing 11 to regulate excessive displacement. On the other hand, when displaced downward, the excessive displacement of the movable housing 12 is regulated by the second displacement regulating projection 12i.

The bottom wall 12d of the movable housing 12 is formed with a plurality of second displacement regulating protrusions 12i protruding downward from the bottom wall 12d. Assuming that the upper wall 12a, the left and right side walls 12b, the rear wall 12c, and the bottom wall 12d of the movable housing 12 are "movable housing main bodies", the second displacement regulating projection 12i is a vertical wall-shaped "leg" protruding from the movable housing main body. It is formed as a "part". The second displacement regulating projection 12i has a length along the front-rear direction Y of the movable housing 12 from the rear wall 12c toward the fitting port 12e. The length of the second displacement regulating projection 12i along the front-rear direction Y is approximately half the length of the movable housing 12 in the front-rear direction Y. The second displacement regulating projection 12i is arranged so as to face the substrate surface P10a of the first substrate P10. The second displacement regulating projection 12i can regulate the excessive downward displacement of the movable housing 12 by abutting the bottom contact surface 12i1 with the substrate surface P10a. The bottom contact surface 12i1 is formed as a rectangular surface having a length substantially half along the front-rear direction Y of the movable housing 12. Therefore, the bottom contact surface 12i1 can be in plane contact with the substrate surface P10a with a length of approximately half along the front-rear direction Y of the movable housing 12. Therefore, even if the movable housing 12 abuts on the substrate surface P10a in an inclined posture, the movable housing 12 can be corrected to a non-tilted posture by making the bottom contact surface 12i1 and the substrate surface P10a come into flat contact with each other. ..

Movable gaps G1 and G3 to G5 are formed between the fixed housing 11 and the movable housing 12. Further, a movable gap G2 is also formed between the movable housing 12 and the substrate surface P10a of the first substrate P10. That is, the movable housing 12 is supported in a state of being displaceable in the three-dimensional direction by the movable portion 13c formed of the elastically deformable spring piece of the terminal 13. Since the movable housing 12 has movable gaps G1 to G5 around it, the movable housing 12 can be displaced in the left-right direction X, the front-rear direction Y, and the up-down direction Z as described above.

Terminal 13
The terminal 13 includes a plurality of first terminals 13A and a plurality of second terminals 13B. The first terminal 13A and the second terminal 13B are different in that the shape of the movable portion 13c described later and the contact portion 13e described later are arranged upside down with each other. However, the terminal structure is common. Therefore, the first terminal 13A will be described. Regarding the same configuration as the first terminal 13A, the same reference numerals are given to the second terminal 13B, and duplicate description will be omitted.

The first terminal 13A is made of a conductive metal piece, and has a substrate connecting portion 13a, a fixed housing fixing portion 13b, a movable portion 13c, a movable housing fixing portion 13d, and a contact portion 13e.

The board connection portion 13a is soldered to the circuit contacts of the first board P10.

The fixed housing fixing portion 13b is press-fitted and held in the fixed housing terminal fixing groove 11e of the fixed housing 11 (see FIG. 4).

The movable portion 13c is formed in a waveform having a mountain-shaped wave portion and a valley-shaped wave portion in order from the rear wall 11c side in the front-rear direction Y. The movable portion 13c is formed from a first extension portion 13c1 extending from the fixed housing fixing portion 13b, an inverted U-shaped first bending portion 13c2 connected to the first extension portion 13c1, and a first bending portion 13c2. It has a U-shaped portion 13c3 that extends, a second extending portion 13c4 that connects the U-shaped portion 13c3 and the fixing portion 13d for the movable housing.

In the first terminal 13A and the second terminal 13B, the first bent portion 13c2 is bent at a position higher in the height direction Z than the second extending portion 13c4 (fixed side portion with respect to the movable housing 12). As a result, the first bent portion 13c2 has a terminal structure in which the U-shaped portion 13c3 and the second extending portion 13c4 are cantilevered and supported so as to suspend them. The lower end portion of the U-shaped portion 13c3 has a bent shape with a corner having a linear horizontal piece 13c6 along the front-rear direction Y between the two corner portions 13c5. Therefore, the first straight line portion 13c7 and the second straight line portion 13c8 can be formed to be long, and the first straight line portion 13c7 and the second straight line portion 13c8 are likely to be elastically deformed in the front-rear direction Y. That is, the movable portion 13c can be easily deformed with a relatively small elastic force. Therefore, the movable housing 12 can be easily displaced with a small force.

The movable portion 13c of the adjacent first terminal 13A and the movable portion 13c of the second terminal 13B are arranged so as to be displaced back and forth so as not to overlap each other in the terminal arrangement direction X. The first bent portion 13c2 of the second terminal 13B is arranged at a height exceeding the horizontal piece 13c6 of the U-shaped portion 13c3 of the first terminal 13A, but does not overlap in the terminal arrangement direction X. , The positions are shifted in the front-rear direction Y. Therefore, even if the movable housing 12 is displaced in the left-right direction X and the movable portion 13c of the first terminal 13A and the movable portion 13c of the second terminal 13B are elastically deformed, conduction contact between the adjacent movable portions 13c is prevented. Will be done. Further, the first bent portion 13c2 of the second terminal 13B is arranged at a height exceeding the lower end (U-shaped portion 13c3) of the first terminal 13A, so that the movable portion 13c of the second terminal 13B is arranged. Spring length can be secured as long as possible. As a result, the movable portion 13c can be elastically deformed softly in the left-right direction X, the front-back direction Y, and the height direction Z. Further, the first bent portion 13c2 of the second terminal 13B may be arranged at a height not exceeding the lower end of the first terminal 13A, but in this case, the movable housing 12 is made higher. It is necessary to arrange the fixed housing 11, and the height of the fixed housing 11 also increases and the size increases. On the other hand, since the first bent portion 13c2 of the second terminal 13B is arranged at a height exceeding the lower end (U-shaped portion 13c3) of the first terminal 13A, the arrangement of the movable housing 12 is lowered. However, the height of the fixed housing 11 can be reduced.

The movable portion 13c of the first terminal 13A and the movable portion 13c of the second terminal 13B are arranged in two upper and lower stages in the height direction Z, and support the movable housing 12 in a cantilever shape. Therefore, the movable portion 13c of the first terminal 13A and the movable portion 13c of the second terminal 13B can exert a sufficient supporting force with respect to the movable housing 12. As a result, the movable housing 12 is supported in a floating state while maintaining a horizontal posture as much as possible.

The movable housing fixing portion 13d has a plate thickness direction changing portion 13d1 and a fixing base portion 13d2 (see the second terminal 13B in FIG. 8). The movable portion 13c described above is formed as a bent terminal type movable portion in which the plate surface of the terminal material is the upper surface and the lower surface. On the other hand, the fixed base portion 13d2 and the contact portion 13e are formed as punched terminal type contact portions in which the plate surface of the terminal material is along the height direction Z. Therefore, it is necessary to change the plate thickness direction between the movable portion 13c and the movable housing fixing portion 13d. The plate thickness direction conversion unit 13d1 is a portion that bends the plate thickness direction by 90 ° for that purpose. The fixed base portion 13d2 is a portion held by press fitting into the terminal accommodating groove 12g of the movable housing 12.

The contact portion 13e has an elastic arm 13e1 extending from the fixed base portion 13d2 and a contact portion 13e2 (see the second terminal 13B in FIG. 8). The elastic arm 13e1 is a spring piece and can be elastically deformed in the height direction Z in the terminal accommodating groove 12g. The contact portion 13e2 is a portion that protrudes from the terminal accommodating groove 12g into the fitting chamber 12f and makes conductive contact with the mating connector 40. The contact portion 13e2 presses and contacts the mating connector 40 with a predetermined contact pressure by the elastic force of the elastic arm 13e1.

Mating connector 40

The mating connector 40 includes a mating housing 41 made of a resin molded body and a plurality of mating terminals 42 made of a conductive metal piece. As shown in FIG. 5, the mating housing 41 has a main body portion 41a and a base portion 41b. The main body 41a is formed in a plate shape, and a plurality of terminal arrangement grooves 41c are formed on the surface thereof. The base portion 41b is formed at both ends in the left-right direction X, and is formed with a length exceeding the height of the fitting port 12e of the movable housing 12 in the height direction Z.

How to fit the right angle connector 10 and the mating connector 40

The fitting method of the right angle connector 10 and the mating connector 40 includes at least the following process.
(1) “First process” of fitting the mating connector 40 to the movable housing 12 (FIG. 6B, initial fitting state).
(2) When the right angle connector 10 and the mating connector 40 are brought closer to each other, the fitting position between the movable housing 12 and the mating connector 40 is rather than the fitting position between the movable housing 12 and the mating connector 40 after the first process. "Second process" (Fig. 6C, deepest mating state).
(3) The contact portion 13e2 of the terminal 13 and the mating terminal 42 of the mating connector 40, and the right angle connector 10 and the mating connector 40 while maintaining the contact position between the contact portion 13e2 and the mating connector 40 after the second process. As the mating movable housing 12 and the mating connector 40 move in the direction away from each other (the movable housing 12 and the mating connector 40 move in the returning direction), the movable portion 13c of the terminal 13 moves into the movable housing 12. A "third process" (FIG. 6D) that forms a "movable mating state" that displaceably supports the connector in multiple directions including the mating direction Y and the removal direction Y.

The fitting method of the right angle connector 10 and the mating connector 40 will be described in more detail based on the first to third steps. Here, FIGS. 6, 7, and 12 are schematic views for facilitating understanding, and the configuration of each member is shown in a simplified manner. In FIGS. 8 to 11, the first support member P11 and the second support member P21 are omitted for simplification of the illustration.

There are the following three patterns in which the right angle connector 10 and the mating connector 40 are fitted.
[Mating mode 1] Only the mating connector 40 moves and fits with the right angle connector 10 in an immobilized state.
[Matching mode 2] Only the right angle connector 10 moves and fits with the mating connector 40 in an immovable state.
[Mating mode 3] Both the right angle connector 10 and the mating connector 40 move to fit each other.

In the case of the fitting mode 1, the “fitting direction Y” refers to, for example, the direction in which the mating connector 40 approaches the right angle connector 10 (direction from right to left in the drawing) in FIG. 6A. The “removal direction Y” also refers to the direction in which the mating connector 40 is separated from the right angle connector 10 (direction from left to right in the drawing) in FIG. 6A. In the case of the fitting mode 2, the directions opposite to the fitting mode 1 are the fitting direction Y and the removal direction Y. In the case of the fitting mode 3, the "fitting direction Y" is the direction from the left to the right in the drawing for the right angle connector 40, and the opposite direction for the mating connector 40. The “removal direction Y” is the direction from right to left in the drawing for the right angle connector 40, and the opposite direction for the mating connector 40. In the following description, in order to facilitate understanding, the fitting mode 1 will be illustrated and described.

State before mating [Fig. 6A, Fig. 8]

The process shown in FIGS. 6A and 8 shows a “pre-fitting state”. As shown in FIG. 6A, the right angle connector 10 is mounted on the first substrate P10, and the first substrate P10 is supported by the first support member P11. The first support member P11 is a "first attachment object" on which the first substrate P10 is installed. The "first object to be attached" may be, for example, a fixed structure such as a housing, a frame, or a bracket of an electric device. The mating connector 40 is mounted on the second substrate P20, and the second substrate P20 is supported by the second support member P21. The second support member P21 is a "second mounting object" on which the second substrate P20 is installed. The "second mounting object" may be, for example, a fixed structure such as a housing, a frame, or a bracket of an electric device. In the pre-fitting state shown in FIGS. 6A and 8, the right angle connector 10 and the mating connector 40 are separated from each other and are not mechanically and electrically connected.

In the pre-fitting state, movable gaps G1 to G5 are formed around the movable housing 12 (FIGS. 3, 6A and 8). The movable housing 12 can move in the accommodation space 11d in the three-dimensional direction within the range of the movable gaps G1 to G5. As a result, even when the mating housing 41 of the mating connector 40 is inserted with respect to the fitting port 12e of the right angle connector 10 in the vertical direction Z and the horizontal direction X, the movable housing 12 corresponds to the misalignment. Since it can be displaced, the mating connector 40 can be inserted into the fitting port 12e.

Initial mating state [Fig. 6B, Fig. 9]

The process shown in FIGS. 6B and 9 is an "initial fitting state" as a "first process". As shown in FIG. 6B, the second substrate P20 (or the second support member P21) is brought closer to the first substrate P10 (or the first support member P11) which is in the immobilized state from the pre-fitting state. It moves in the direction (fitting direction Y) and fits the main body 41a of the mating housing 41 into the fitting chamber 12f of the right angle connector 10. Then, first, the insertion side end portion 41a1 of the main body portion 41a presses and contacts the contact portion 13e2 of the first terminal 13A and the second terminal 13B protruding into the fitting chamber 12f. When the mating connector 40 is pushed into the movable housing 12 as it is, the elastic force for elastically deforming the movable portion 13c is smaller than the insertion force for the mating connector 40 for the contact portion 13e2 to ride on the mating terminal 42, so that it is movable. The movable housing 12 moves in the fitting direction Y by elastically deforming the portion 13c so as to compress in the fitting direction Y. The movement of the movable housing 12 in the fitting direction Y is stopped when the rear contact surface 12h1 of the first displacement regulating projection 12h comes into contact with the contact receiving portion 11f of the fixed housing 11. When the mating connector 40 is further pushed in after the movable housing 12 has stopped moving, the inclined surface of the insertion side end portion 41a1 abuts on the contact portion 13e2 and is pushed out outward, after which the contact portion 13e2 inserts the mating terminal 42. Contact the side edge. If the mating connector 40 is continuously inserted into the fitting chamber 12f (as the mating position between the right angle connector 10 and the mating connector 40 is deepened), the elastic arm 13e1 bends outward and the contact portion 13e2 becomes the mating portion. Ride on terminal 42. Further, as the fitting position of the mating housing 41 in the fitting chamber 12f becomes deeper, the effective fitting length of the contact portion 13e2 gradually increases. Then, by arranging the second substrate P20 at the regular installation position, an "initial mating state" between the right angle connector 10 shown in FIGS. 6B and 9 and the mating connector 40 is formed.

Here, in FIGS. 6B and 9, the rear contact surface 12h1 is in contact with the contact receiving portion 11f, and the first substrate P10 (first support member P11) and the second substrate P20 (second support member) are shown. P21) shows a state in which each of them is fixed at a regular installation position of the electric device. In the initial fitting state, in addition to the states shown in FIGS. 6B and 9, the mating connector 40 slightly enters the fitting chamber 12f even after the rear contact surface 12h1 comes into contact with the contact receiving portion 11f. It may be pushed. In such a case, for example, when the second substrate P20 has a warp protruding in the fitting direction Y, the first substrate P10, the second substrate P20, the first support member P11, and the second support member P21 When the installation position of the first substrate P10 is deviated to the position closer to the second substrate P20 due to the cumulative intersection in the assembly including the second substrate P20, the installation position of the second substrate P20 is to the position closer to the first substrate P10. If they are misaligned, the installation positions of both the first substrate P10 and the second substrate P20 may be deviated to positions close to each other. In such a case, after the rear contact surface 12h1 is once in contact with the contact receiving portion 11f (FIGS. 6B and 9), the rear contact surface 12h1 may be slightly separated from the contact receiving portion 11f. In such a case, the initial fitting state is a state in which the rear contact surface 12h1 is slightly separated from the contact receiving portion 11f. In this case, the movable housing 12 can be displaced by the movable portion 13c until the rear contact surface 12h1 comes into contact with the contact receiving portion 11f even in the initial fitting state.

In the initial fitting state shown in FIGS. 6B and 9, the first substrate P10 is fixed to the regular installation position by the first support member P11. The second substrate P20 is also fixed at a regular installation position by the second support member P21. That is, FIGS. 6B and 9 show a fitting structure 1 of the right angle connector 10 and the mating connector 40 provided at the regular installation position of the electric device.

In the initial fitting state, the movable portion 13c is elastically deformed so as to shrink toward the rear wall 11c. Therefore, the movable portion 13c generates a restoring force in the removal direction Y, but as described above, the first substrate P10 and the second substrate P20 are structurally fixed at the regular installation positions. Therefore, the movable housing 12 is not pushed back in the removal direction Y by the restoring force of the movable portion 13c.

In the initial fitting state, the movable gaps G1 to G3 and G5 are formed between the fixed housing 11 and the movable housing 12 except for the movable gap G4 between the first displacement regulating projection 12h and the contact receiving portion 11f. It is formed. Therefore, the movable housing 12 can move in the left-right direction X and the up-down direction Z. The movable housing 12 can also move in the removal direction Y.

In the initial mating state, the contact portion 13e2 of the first terminal 13A and the contact portion 13e2 of the second terminal 13B are in pressure contact with the mating terminal 42 by a predetermined contact pressure. As a result, a holding force is generated between the contact portion 13e2 and the mating terminal 42. More specifically, the holding force is such that the contact portion 13e2 and the mating terminal 42 do not slide in the mating direction Y and the mating direction Y in the mating connection state of the right angle connector 10 and the mating connector 40. It is a force that maintains the contact position with each other. The elastic force of the movable portion 13c for elastically deforming in the fitting direction Y and the pulling-out direction Y is smaller than the holding force thereof. Therefore, in the initial mating state, the contact portion 13e2 and the mating terminal 42 are in conductive contact in a state of exerting a holding force, the movable portion 13c is elastically deformed, and the movable housing 12 is displaced in the horizontal direction X and the vertical direction Z. Even if the mating connector 40 is displaced in the removal direction Y, the contact portion 13e2 and the mating terminal 42 can maintain their contact positions without sliding.

In the initial mating state, as shown in FIGS. 6B and 9, the right angle connector 10 and the mating connector 40 as a connection target are electrically connected. Therefore, the board circuit of the first board P10 and the board circuit of the second board P20 are electrically connected.

In the initial fitting state, a fitting gap S1 is formed between the indoor bottom surface 12f1 of the fitting chamber 12f and the insertion side end portion 41a1 of the main body portion 41a. Further, a fitting gap S2 is also formed between the fitting port 12e and the base portion 41b. Therefore, in the initial fitting state, the mating connector 40 can be further inserted into the back of the fitting chamber 12f. By having the fitting gaps S1 and S2 in the initial fitting state in this way, when the mating housing 40 and the movable housing 12 are mated, the portion of the mating housing 40 facing each other in the mating direction Y Since the movable housing 12 does not come into contact with the portion, damage to the housing can be prevented. Further, the depth of the fitting position between the movable housing 12 (fitting chamber 12f) and the mating connector 40 (main body portion 41a) in the deepest fitting state can be provided with a degree of freedom. That is, it is possible to realize the fitting structure 1 in which the deepest fitting state can be obtained according to the magnitude of the force (vibration, impact, resonance) acting on the fitting structure 1 in the initial fitting state.

Deepest mating state [Fig. 6C, Fig. 10, Fig. 7A]

The process shown in FIGS. 6C and 10 shows the "deepest mating state" as the "second process". In the initial fitting state, fitting gaps S1 and S2 are formed. When a force (vibration, shock, vibration due to resonance, etc.) acts on the fitting structure 1 in the initial fitting state, the fixed housing 11 and the mating connector 40 may be displaced in the approaching direction. FIG. 6C shows an example thereof, and shows a state in which the second substrate P20 is bent in a direction approaching the right angle connector 10. The deflection of the second substrate P20 occurs when vibration or impact transmitted from the installation environment acts on the second substrate P20 through the second support member P21, or when the second substrate P20 resonates due to such vibration or impact. It can happen.

When the mating connector 40 is displaced in the fitting direction Y due to the bending of the second substrate P20, the fitting position between the movable housing 12 and the mating connector 40 becomes deeper than the fitting position in the initial mating state. Along with this, the contact position between the contact portion 13e2 and the mating terminal 42 in the initial fitting state also moves as the fitting position becomes deeper. Therefore, contact sliding occurs in the process of shifting from the initial fitting state to the deepest fitting state. In this way, the deepest fitting state in the fitting structure 1 is formed.

In the example of FIG. 6C, an example in which the second substrate P20 bends is shown, but as shown in FIG. 7A, the first substrate P10 moves so as to approach the mating connector 40 in the immobilized state, so that the deepest fitting is achieved. Conditions may be formed. In the example of FIG. 7A, the first substrate P10 is subjected to a force (vibration, impact, etc.) such that the first support member P11 supporting the first substrate P10 is shaken in the removal direction Y, so that the first substrate P10 is second. An example of displacement in the direction approaching the substrate P20 of the above is shown. Although not shown, the second substrate P20 bends in the fitting direction Y (front direction of the front-rear direction Y) as shown in FIG. 6C, and the first substrate P10 is shown in FIG. 7A. Is displaced in the removal direction Y (rear direction of the front-rear direction Y) at the same time, so that the deepest fitting state may be formed.

Regarding the fitting gaps S1 and S2, for example, as shown in FIG. 12A, the fitting gap S1 is shorter than the fitting gap S2 so that the insertion side end portion 41a1 comes into contact with the indoor bottom surface 12f1 in the deepest fitting state. It can also be formed. For this purpose, the length of the fitting chamber 12f along the insertion direction Y is formed shorter than the length of the main body portion 41a along the insertion direction Y. By adopting the fitting structure 1 in which the insertion side end portion 41a1 is fitted to the bottom surface 12f1 of the room in the deepest fitting state until the insertion side end portion 41a1 abuts, the effective fitting length (from the fitting port 12e to the mating terminal 42 of the contact portion 13e2) The distance to the contact position) can be secured for a long time, and reliable connection reliability can be obtained.

Regarding the fitting gaps S1 and S2, as shown in FIG. 12B, for example, in the deepest fitting state (FIGS. 6C and 10), the fitting gap S1 is formed without contact between the indoor bottom surface 12f1 and the insertion side end portion 41a1. On the other hand, it can be formed so that the fitting gap S2 does not remain by contacting the base portion 41b with the fitting opening 12e.

Movable mating state [Fig. 6D, Fig. 11]

The process shown in FIGS. 6D and 11 shows a "movable fitting state" as a "third process". In the deepest fitting state shown in FIG. 6C, the second substrate P20 is bent, and when the bending of the second substrate P20 returns, the movable fitting state shown in FIG. 6D is formed. In the movable fitting state, the fitting position between the movable housing 12 and the mating connector 40 in the deepest fitting state is maintained. The fitting position is maintained by the holding force between the contact portion 13e2 and the mating terminal 42. In the movable fitting state, movable gaps G1 to G5 are formed between the movable housing 12 and the fixed housing 11, and the movable housing 12 sets the accommodation space 11d in the three-dimensional direction within the range of the movable gaps G1 to G5. Can be displaced. Even if the movable portion 13c is elastically deformed and the movable housing 12 is displaced in the three-dimensional direction, the contact portion 13e2 and the mating terminal 42 are in conductive contact with each other while exerting a holding force. That is, the contact portion 13e2 and the mating terminal 42 can maintain the contact position without sliding with each other. As described above, even in the right angle connector 10, the movable housing 12 can be displaced in the three-dimensional direction with respect to the fixed housing 11 without the contact portion 13e2 and the mating terminal 42 sliding in contact with each other. Connection reliability can be maintained without plating peeling occurring at the contact portion of 13e2 and the mating terminal 42.

Displacement in the removal direction from the movable mating state [Fig. 6E, Fig. 7B]

The process shown in FIG. 6E shows a "movable fitting state". More specifically, it shows a state in which the movable housing 12 is displaced in the removal direction Y from the movable fitting state of FIG. 6D. When a force (vibration, shock, vibration due to resonance) acts on the fitting structure 1 in the movable fitting state (FIG. 6D), the fixed housing 11 and the mating connector 40 may be relatively separated from each other. In the example shown in FIG. 6E, the movable housing 12 is displaced in the direction away from the fixed housing 11 by bending the second substrate P20 in the removal direction Y. Even in such a case, the movable housing 12 can be displaced with respect to the fixed housing 11 in the removal direction Y of the mating connector 40. Then, as described above, the contact portion 13e2 and the mating terminal 42 do not slide with each other and maintain the contact position, so that the contact does not slide. Therefore, the connection reliability can be maintained without plating peeling occurring at the contact portions of the contact portion 13e2 and the mating terminal 42.

FIG. 6E shows an example in which the movable housing 12 is displaced in the direction away from the fixed housing 11 by bending the second substrate P20 in the removal direction Y. However, as shown in FIG. 7B, for example, when the first substrate P10 is displaced in the mating direction Y of the mating connector 40, the movable housing 12 may be displaced in a direction away from the fixed housing 11. In the example of FIG. 7B, a force (vibration, impact, etc.) that causes the first support member P11 that supports the first substrate P10 to swing in the fitting direction Y (rear direction of the front-rear direction Y) acts. In this example, the first substrate P10 is displaced in the direction away from the second substrate P20. Although not shown, movable fitting occurs when the second substrate P20 bends in the removal direction Y and the first substrate P10 is displaced in the fitting direction Y at the same time as shown in FIG. 6E. From the state (FIG. 6D), the movable housing 12 can be displaced with respect to the fixed housing 11 in the removal direction Y.

Displacement in the mating direction from the movable mating state [Fig. 6C]

The movable housing 12 can be displaced from the movable fitting state of FIG. 6D or the movable fitting state of FIG. 6E to the state shown in FIG. 6C.

Features of this embodiment

Specifically, in the right angle connector 10, the movable housing 12 can be displaced in the three-dimensional direction in the initial fitting state and the movable fitting state, and at that time, the occurrence of contact sliding can be suppressed, so that the connection reliability Sex can be maintained.

Second Embodiment [FIGS. 13 and 14]

In the right angle connector 10 of the first embodiment, an example in which the contact receiving portion 11f is formed of the resin wall of the fixed housing 11 is shown, but the right angle connector 20 of the present embodiment is formed on the resin wall of the fixed housing 11. It differs from the first embodiment in that the fixed housing 11 is provided with the first receiving tool 15 as a “receiving member” instead. Other than that, it is the same as the first embodiment.

The first receiver 15 is formed of a flat metal piece, and is held in the fixed housing 11 by press-fitting the receiver accommodating groove 11i provided in the fixed housing 11 from the bottom surface side of the fixed housing 11. (Fig. 14). According to the present embodiment including the first receiver 15, it can be configured to have a function and a feature suitable for receiving the movable housing 12 which does not depend on the material and structure of the fixed housing 11.

Although the first receiver 15 is exemplified by a flat metal piece, it can also be formed of a hard resin plate.

Third Embodiment [FIGS. 15 and 16]

In the right angle connector 10 of the first embodiment, an example in which the contact receiving portion 11f is formed of the resin wall of the fixed housing 11 is shown, but the right angle connector 30 of the present embodiment is formed on the resin wall of the fixed housing 11. It differs from the first embodiment in that the fixed housing 11 is provided with the second receiving tool 16 as the “receiving member” instead. Further, the second receiver 16 of the present embodiment is the same as the fixing bracket 14 of the first embodiment, and is also used as a fixing bracket for fixing the fixing housing 11 to the first substrate P10. It is different from the fixing bracket 14 of the embodiment and the first receiver 15 of the second embodiment. Other than that, it is the same as the first embodiment.

The second receiver 16 is formed of a metal piece, and is in contact with the substrate fixing portion 16a, the fixing piece portion 16b press-fitted into the fixing housing 11, and the rear portion of the movable housing 12 with the first displacement regulating projection 12h. A receiving portion 16c that comes into contact with the surface 12h1 is provided. The substrate fixing portion 16a has a thin plate shape arranged along the substrate surface P10a. The fixed piece portion 16b is bent and extends in the height direction Z from the substrate fixing portion 16a, and is press-fitted and held by a receiver fixing portion (not shown) provided on the side wall 11b of the fixed housing 11. .. The substrate fixing portion 16a and the fixing piece portion 16b are formed in an L shape. The receiving portion 16c is formed in a flat plate shape that bends and extends in the left-right direction X from the trailing edge of the fixed piece portion 16b in the front-rear direction Y, and is positioned so as to face the rear contact surface 12h1 of the movable housing 12 in the front-rear direction Y. doing.

The substrate fixing portion 16a is fixed to the first substrate P10 by soldering. Then, the receiving portion 16c receives the contact of the rear contact surface 12h1 of the first displacement regulating projection 12h of the movable housing 12. According to the present embodiment, since the second receiver 16 can also be used as a fixing bracket for fixing the fixed housing 11 to the first substrate P10, the number of parts can be reduced.
