Abstract

PROBLEM TO BE SOLVED: To provide a connector capable of suppressing degradation of the spring property of a terminal without increasing the number of components.SOLUTION: A connector comprises a housing with a connection hole to which a plug can be inserted and a terminal held by the housing. The terminal has a substantially U-shaped spring portion 210a, a contact portion 220a that can be in contact with a plug terminal and also can be in contact with a body of a plug at a height lower than the terminal, and a bent portion 230a provided between a first end 211a of the spring portion and the contact portion. The bent portion is bent toward the side of a second end 212a and inclined upward to a direction where the contact portion is apart from the second end and to a back side of the connection hole. The height of the spring portion is designed so that the first end does not contact with a plug within the connection hole.

Description

  The present invention relates to a connector having a connection hole into which two or more mating connectors can be inserted.

  As a conventional connector, a housing having a connection hole into which a 6-pin modular plug having 6 terminals and an 8-pin modular plug having 8 terminals can be inserted, and a fixed terminal disposed in the connection hole of the housing, A movable terminal disposed on both sides of the fixed terminal in the connection hole of the housing and rotatable from the connection position to the retracted position, an urging spring that elastically holds the movable terminal in the retracted position, and connected to the movable terminal And a drive arm disposed in the connection hole. The connection position is a position where the movable terminal appears in the connection hole, and the retracted position is a position where the movable terminal is retracted from the connection hole.

  When the 8-pin modular plug is inserted into the connection hole, the 8-pin modular plug presses the drive arm against the urging force of the urging spring, so that the movable terminal is rotated from the retracted position to the connected position and is movable. The terminal and the fixed terminal are in contact with the terminals of the 8-pin modular plug, respectively. On the other hand, when the 6-pin modular plug is inserted into the connection hole, since the movable terminal is located at the retracted position, the fixed terminal contacts the terminal of the 6-pin modular plug. As described above, the conventional connector prevents the deterioration of the spring property of the movable terminal by avoiding the interference between the 6-pin modular plug and the movable terminal when the 6-pin modular plug is inserted. The deterioration of the spring property of the movable terminal occurs when the movable terminal is pressed against the body of the 6-pin modular plug whose height is lower than the terminal of the 8-pin modular plug, and the movable terminal is excessively elastically deformed.

  However, the connector requires an urging spring and a driving arm as a mechanism for preventing the spring property of the movable terminal from being deteriorated, which increases the number of parts and increases the cost.

  The present invention was devised in view of the above circumstances, and an object of the present invention is to provide a connector capable of suppressing deterioration of the spring property of a terminal without increasing the number of components. is there.

  In order to solve the above problems, the connector of the present invention includes an insulating housing having a connection hole into which the first and second mating connectors can be inserted, and a first terminal held by the housing. The first terminal has first and second ends, and a substantially U-shaped or substantially V-shaped spring portion arranged with the first and second ends facing the back side of the connection hole. And a contact portion that is disposed in the connection hole of the housing and can contact the terminal of the first mating connector, and can contact the body of the second mating connector at a height position lower than the terminal, A first bent portion provided between the first end of the spring portion and the contact portion; The first bent portion is bent toward the second end portion of the spring portion, the contact portion is inclined upward in the direction away from the second end portion of the spring portion and the back side of the connection hole, The height dimension is such that the first end does not contact the second mating connector inserted into the connection hole.

  In the case of such a connector, the first bent portion that is bent toward the second end of the spring portion is provided between the first end of the spring portion of the first terminal and the contact portion. Even if the second mating connector is inserted into the connection hole of the housing and the body of the second mating connector presses the contact portion at a height position lower than the terminal of the first mating connector, the first bent portion and the spring portion are By elastically deforming each, the load applied to the first terminal can be distributed. Therefore, without increasing the number of parts, it is possible to suppress the deterioration of the spring property of the first terminal, and it is possible to prevent the contact reliability of the first terminal with respect to the terminal of the first mating connector. The height of the spring portion is such that the first end does not contact the second mating connector inserted into the connection hole, and the first bent portion is bent toward the second end of the spring portion. As a result, the height position of the first end of the spring portion is lowered. That is, since the first end portion of the spring portion functions as a relief portion that does not interfere with the body of the second mating connector, the first end portion of the spring portion interferes with the second mating connector, and the spring portion excessively elastically deforms. Thus, it is possible to avoid deterioration of the spring property of the spring portion. Further, in order to avoid interference between the first end portion of the spring portion and the second mating connector, it is not necessary to extremely reduce the height of the spring portion, and a decrease in spring characteristics of the spring portion can be avoided. Furthermore, since the first end portion of the spring portion functions as a relief portion, by increasing the length of the spring portion, the spring constant of the first terminal is reduced and the displacement of the first end portion of the spring portion is reduced. Can be increased. In other words, in order to reduce the spring constant of the first terminal and increase the amount of displacement of the first end of the spring part, even if the length of the spring part is increased, the first end of the spring part is the relief part. Therefore, interference between the first end of the spring portion and the body of the second mating connector can be avoided.

  The first terminal may further include a second bent portion provided between the first bent portion and the contact portion. The second bent portion is bent in a direction opposite to the bending direction of the first bent portion, and the inclination angle of the contact portion is reduced.

  In this case, the inclination angle of the contact portion is reduced by bending the second bent portion in a direction opposite to the bending direction of the first bent portion. Therefore, when the contact portion is inclined upward from the second end portion of the spring portion and toward the back side of the connection hole, the inclination angle of the contact portion is increased, and the first mating connector of the contact portion is increased. It is possible to suppress an increase in the discharge power against the.

  The connector further includes a second terminal held by the housing. The second terminal can be configured to be able to contact a part of the first mating connector and all the terminals of the second mating connector in the connection hole. Alternatively, the second terminal may be configured to contact the terminal of the second mating connector within the connection hole. In the former case, the contact portion of the first terminal can contact the remaining terminals of the first mating connector.

The holding piece 370 is folded back toward the back side of the connection hole 110a and is inclined upward toward the back side of the connection hole 110a. Parts other than the tip of the holding piece 370 are accommodated in the retracting recess 114a of the housing body 100a. The tip of the holding piece 370 protrudes from the retracting recess 114a and is located in the connection hole 110a, and elastically holds both side surfaces in the width direction X of the body 11 of the 8-pin plug 10 inserted into the connection hole 110a. It is possible. A top plate 330 is connected to the upper end of the front plate 310, and a bottom plate 340 is connected to the lower end of the front plate 310, and is bent at a right angle to the front plate 310.

  The top plate 330 is a substantially rectangular plate and covers the upper surface of the housing body 100a. The bottom plate 340 is a substantially rectangular plate having a length dimension in the front-rear direction Y smaller than that of the top plate 330, and covers the tip of the lower surface of the housing body 100a. Side plates 350 are suspended from both ends of the top plate 330 in the width direction X. The side plate 350 is a downward substantially L-shaped plate that partially covers the both side surfaces of the housing body 100a. A rectangular notch 351 is formed at the lower end of the side plate 350. Further, a locking projection 352 (one shown in the figure) is provided at the rear end of the side plate 350. Two downwardly approximately L-shaped connection pieces 360 are provided at the edges of the notches 351. The connection piece 360 can be soldered to the through-hole electrode of the substrate. The back plate 320 is a substantially rectangular conductive plate that is separate from the front plate 310, the top plate 330, the bottom plate 340, the side plate 350, the connection piece 360, and the holding piece 370. The height dimension of the back plate 320 is substantially the same as the dimension from the upper end of the side plate 350 to the edge of the notch 351. A pair of locking plates 321 are provided at both ends in the width direction X of the back plate 320. The locking plate 321 is provided with a rectangular locking hole 321a (one in the figure) for locking the locking projection 352. That is, the locking plate 321 is attached to the rear end portion of the side plate 350 and covers the upper end portion on the back surface of the housing body 100a.

  Hereinafter, the assembly procedure of the connector having the above-described configuration will be described in detail. Terminals 200a to 200h prepared by press molding a metal plate having conductivity are prepared. Along with this, a terminal holding part 100b prepared by injection molding of an insulating resin is prepared. Thereafter, while inserting the horizontal part 101b of the terminal holding part 100b between the contact part 220a of the terminal 200a and the vertical press-fitting part 270a, the front-side accommodation groove 130b, the upper accommodation groove 110b, and the lower accommodation groove of the terminal holding part 100b. The spring part 210a of the terminal 200a is inserted into 120b. At this time, the horizontal press-fitting part 260a of the terminal 200a is inserted into the lower press-fitting groove 140b of the terminal holding part 100b, and the vertical press-fitting part 270a of the terminal 200a is inserted into the vertical press-fitting groove 150b of the terminal holding part 100b. The press-fit portion main body 261a is press-fitted into the press-fit recess 141b of the lower press-fit groove 140b, and the press-fit portion main body 271a of the vertical press-fit portion 270a is press-fitted into the vertical press-fit groove 150b. Thus, the terminal 200a is attached to the terminal holding part 100b. The terminals 200b to 200h are attached to the terminal holding part 100b similarly to the terminal 200a.

  Then, the housing main body 100a created by injection molding insulating resin is prepared. The horizontal portion 101b of the terminal holding portion 100b is inserted into the mounting hole 114a of the housing main body 100a from the rear. Then, a pair of rail part 103b of the terminal holding | maintenance part 100b is guided to the guide groove 130a of the housing main body 100a. Thereafter, when the horizontal portion 101b is fitted into the mounting hole 120a, the vertical portion 102b of the terminal holding portion 100b is fitted into the fitting recess 160a of the housing body 100a from the rear. At this time, the pair of locking projections 104b of the terminal holding portion 100b is locked in the locking holes 140a of the housing body 100a. Thereby, the terminal holding part 100b is combined with the housing main body 100a, and the spring parts 210a-h held by the terminal holding part 100b connect the first and second ends 211a-h, 212a-h to the back of the connection hole 110a. The tip portions of the contact portions 220a to 220h are inserted into the terminal guide grooves 170a.

  Thereafter, a front plate 310, a top plate 330, a bottom plate 340, a side plate 350, a connection piece 360, and a holding piece 370 formed by press-molding a conductive metal plate are prepared. Thereafter, the housing body 100a and the terminal holding portion 100b are inserted from between the side plates 350, and the front surface of the housing body 100a is brought into contact with the front plate 310. At this time, the top plate 330 is in contact with the upper surface of the housing body 100a, the bottom plate 340 is in contact with the lower surface, and the side plates 350 are in contact with both side surfaces. At the same time, the holding piece 370 is inserted into the retracting recess 114a of the connection hole 110a of the housing body 100a. Thereafter, a back plate 320 formed by press molding a conductive metal plate is prepared. Thereafter, the locking protrusion 352 of the side plate 350 is locked in the locking hole 321 a of the locking plate 321 of the back plate 320. At this time, the back plate 320 contacts the back surface of the housing body 100a.

  When the 8-pin plug 10 to be connected is inserted into the connection hole 110a of the connector thus assembled, the terminal 12 of the 8-pin plug 10 contacts the contact portions 220a-h of the terminals 200a-h at the height position T1. Then press. As a result, the spring portions 210a-h and the first and second bent portions 230a-h, 240a-h of the terminals 200a-h are elastically deformed, and the contact portions 220a-h, the first and second bent portions 230a-h, 240a-h and the first end portions 211a-h are displaced downward. At this time, the tips of the contact portions 220a to 220h move downward in the terminal guide groove 170a of the housing body 100a. Thereby, the 8-pin plug 10 is connected to this connector. At this time, the locking portion 13a of the locking piece 13 of the 8-pin plug 10 is inserted into the locking hole 112a of the connection hole 110a, and both shoulder portions of the locking portion 13a are locked to the pair of locking projections 113a. Thereby, the state where the 8-pin plug 10 is connected to the connector is maintained. In this connected state, the arm 13b of the lock piece 13 protrudes from the connection hole 110a to the outside from between the locking projections 113a. When removing the 8-pin plug 10 from the connector, the arm 13b is moved downward, and the locking portion 13a is displaced downward, so that both the shoulder portions of the locking portion 13a and the locking projection 113a are locked. Canceled. In this state, the 8-pin plug 10 can be pulled out from the connection hole 110a.

  When the 6-pin plug 20 that is not to be connected is erroneously inserted into the connection hole 110a of the connector, the terminal 22 of the 6-pin plug 20 contacts and presses the contact portions 220b to 220g of the terminals 200b to 200g at the height position T3. On the other hand, the body 21 of the 6-pin plug 20 presses the contact portions 220a, h of the terminals 200a, h at the height position T4 (that is, at a height position lower than the height position T1). Thereby, the spring parts 210b-g and the first and second bent parts 230b-g, 240b-g of the terminals 200b-g are elastically deformed in the same manner as when the 8-pin plug 10 is inserted, and the contact parts 220b-g, the first The second bent portions 230b-g, 240b-g and the first end portions 211b-g are displaced downward in the same manner as when the 8-pin plug 10 is inserted, while the spring portions 210a, h of the terminals 200a, h and the first, first The two bent portions 230a, h, 240a, h are elastically deformed to a greater extent than the spring portions 210b-g and the first and second bent portions 230b-g, 240b-g, and the contact portions 220a, h, first, second. The bent portions 230a, h, 240a, h and the first end portions 211a, h are larger than the contact portions 220b-g, the first and second bent portions 230b-g, 240b-g, and the first end portions 211b-g. under Displaced (see Figure 8).

  However, since the first and second bent portions 230a, h, 240a, and h are elastically deformed in addition to the spring portions 210a and h, the terminals 200a and h are not subject to connection. Even if the terminals 200a and h are pressed into the body 21 at the height position T4, the load applied to the terminals 200a and h can be distributed. Thus, by simply providing the first and second bent portions 230a, h, 240a, h on the terminals 200a, h, it is possible to suppress deterioration of the spring properties of the terminals 200a, h due to erroneous insertion of the 6-pin plug 20, A decrease in contact reliability of the terminals 200a and h with respect to the terminal 12 of the 8-pin plug 10 can be suppressed. The height dimension H of the spring part 210a is set to a height dimension in which the first end part 211a does not contact the body 21 of the 6-pin plug 20 inserted into the connection hole 110a, and the first bent parts 230a, h Are bent to the second end portions 212a, h side of the spring portions 210a, h, and the height positions of the first end portions 211a, h are lowered. That is, since the first end portions 211a, h of the spring portions 210a, h function as an escape portion that does not contact the body 21 of the incorrectly inserted 6-pin plug 20, the first end portions 211a of the spring portions 210a, h. , H can interfere with the body 21 of the 6-pin plug 20 that is not to be connected, and the spring portions 210a, h can be elastically deformed excessively, thereby preventing the spring properties of the spring portions 210a, h from deteriorating. In addition, in order to avoid interference between the first end portions 211a, h of the spring portions 210a, h and the body 21 of the 6-pin plug 20, it is not necessary to extremely reduce the height dimension H of the spring portions 210a, h. A decrease in the spring characteristics of the spring portions 210a and h can be avoided. Furthermore, since the first end portions 211a and h of the spring portions 210a and h function as escape portions, the spring constant of the first end portions 211a and h can be reduced by increasing the length of the spring portions 210a and h. Thus, the displacement amount of the first end portions 211a, h of the first end portions 211a, h can be increased. In other words, even if the lengths of the spring portions 210a and h are increased in order to decrease the spring constant of the terminals 200a and h and increase the displacement amount of the first ends 211a and h of the spring portions 210a and h, Since the first end portions 211a and h of the spring portions 210a and h function as escape portions, interference between the first end portions 211a and h of the spring portions 210a and h and the body 21 of the 6-pin plug 20 can be avoided.

  Further, in this connector, the second bent portions 240a to 240h are bent in the direction opposite to the bending direction of the first bent portions 230a to 230h, the inclination angle α of the contact portions 220a to 220h is reduced, and the plug of the contact portion 220a is connected. Efforts to reduce discharge power. Therefore, even if the 8-pin plug 10 with the broken lock piece 13 is inserted into the connection hole 110a, the possibility that the contact portion 220a will eject the 8-pin plug 10 can be reduced.

  The connector described above is not limited to the embodiment described above, and can be arbitrarily changed in design within the scope of the claims. Details will be described below.

  The connector includes the terminals 200a and 200h that are the first terminals and the terminals 200b to 200g that are the second terminals. However, it is sufficient that the connector includes at least the first terminal. For example, when the pitch interval of the terminals of the first mating connector that is the connection target that can be inserted into the connection hole 110a is different from the pitch spacing of the terminals of the second mating connector that is not the connection target, the connector of the present invention is If the first terminal that can contact the terminal of the first mating connector in the connection hole and that can contact the body of the second mating connector at a lower position than the terminal is provided, another terminal is required. do not do.

  In the above connector, the 8-pin plug 10 is an object to be connected and the 6-pin plug 20 is not an object to be connected. However, the present invention is not limited to this. For example, it can be set as the structure which can insert in the connection hole one other party connector which is a connection object, and two or more other party connectors which are not a connection object. Moreover, the said connector can be set as the structure which can insert two or more types of other party connectors which are connection objects into a connection hole. For example, when the connector also includes a 6-pin plug 20, when only the terminals 200 b to 200 g are connected to the terminal 22 of the 6-pin plug 20, a function for recognizing the connector to which the 6-pin plug 20 is connected is added. It ’s fine.

  The first terminal described above has first and second ends, and a substantially U-shaped or V-shaped spring arranged with the first and second ends facing the back side of the connection hole. And a contact portion that is disposed in the connection hole of the housing and can contact the terminal of the first mating connector, and can contact the body of the second mating connector at a height position lower than the terminal, A first bent portion provided between the first end of the spring portion and the contact portion, the first bent portion is bent toward the second end of the spring portion, The contact portion is inclined upward in the direction away from the second end portion of the spring portion and toward the back side of the connection hole, and the height dimension of the spring portion is a second height in which the first end portion is inserted into the connection hole. The design can be arbitrarily changed as long as the dimensions do not contact the mating connector. For example, as in a terminal 200a 'shown in FIG. 10, only the first bent portion 230a' can be provided between the first end 211a 'of the spring portion 210a' and the contact portion 220a '. In this case, even if the 6-pin plug 20 is erroneously inserted and the terminal 200a ′ is pressed against the body 21 of the 6-pin plug 20 at the height position T4, the spring portion 210a ′ and the first bent portion 230a ′ are elastically deformed. , The load applied to the terminal 200a ′ can be distributed. Further, since the first bent portion 230a 'is bent toward the second end portion 212a' of the spring portion 210a ', the first end portion 211a' functions as the above-described escape portion. Therefore, the same effect as the above embodiment can be obtained. Further, since the second bent portion 240a is not provided between the first end portion 211a ′ of the spring portion 210a ′ and the contact portion 220a ′, the inclination angle α ′ of the contact portion 220a ′ is set to the contact portion 220a. The inclination angle α can be made larger. Therefore, the plug discharging force of the contact portion 220a 'can be improved, and the plug 10 or the erroneously inserted plug 20 can be easily pulled out.

  Moreover, about the 2nd terminal mentioned above, as long as it can contact a part of terminal of a 1st other party connector and all the terminals of a 2nd other party connector, it is possible to change a design arbitrarily. In the case where the first and second mating connectors having different terminal pitch intervals can be connected as described above and both the first and second mating connectors are to be connected, The first terminals may be arranged according to the pitch intervals of the terminals of the first counterpart connector, and the second terminals may be arranged according to the pitch intervals of the second counterpart connector. In this case, the 2nd terminal should just be a shape which can contact the terminal of a 2nd other party connector.

  In the above embodiment, the housing 100 includes the housing body 100a and the terminal holding portion 100b. However, the housing 100 has a connection hole into which the first and second mating connectors can be inserted and holds the first terminal. The design can be arbitrarily changed as long as it can be done. For example, the second end of the spring portion of the first terminal can be embedded in the bottom of the connection hole of the housing by insert molding.

  In the above embodiment, the materials, shapes, dimensions, arrangement, etc. constituting each part of the connector have been described as examples, and can be arbitrarily changed as long as the same function can be realized. is there. Moreover, in the said embodiment, although the connector concerning this invention was a receptacle connector for modular jacks, it is not limited to this. The present invention can be applied not only to connectors other than modular jacks but also to plug connectors.
