Description

  The present invention relates to a connector that is mounted on a substrate and is in electrical contact with a connection object.

  A connector in which the terminal has a movable part is used so that the contact state can be maintained even when vibration is applied while the terminal is in conductive contact with the connection object. This movable part is arrange | positioned between the board | substrate connection part mounted in a board | substrate in a terminal, and the contact part which carries out electrical contact with the connection target object. When vibration is generated in the substrate or the connection object, the movable part is elastically deformed to absorb the vibration, and the contact part and the connection object can be kept in conductive contact.

  Such connectors include, for example, a fixed housing that is fixed to a terminal board connection portion of a terminal, and a movable housing that is locked in a state of being relatively displaceable with respect to the fixed housing and that holds a contact portion of the terminal. is there. If a displacement occurs when the connection object is fitted, or if vibration occurs in the board after fitting, the movable part will be elastically deformed due to the elastic deformation of the movable part, and the contact part will be connected. It is possible to continue to contact and follow an object (see Patent Document 1 as an example).

JP 2012-129109 A

  The fixed housing provided in such a conventional connector is formed in a box shape having an opening on the bottom surface facing the substrate, and when assembling the connector, the movable housing is inserted from the opening on the bottom surface into the accommodating portion inside the fixed housing. To do. In a connector having a movable housing insertion opening on the bottom surface of such a fixed housing, the displacement of the movable housing in the direction approaching the substrate is regulated by the movable housing coming into contact with the substrate, and the other direction (front-rear direction, The displacement in the left-right direction and the upward direction away from the substrate is regulated by the protrusion provided on the movable housing coming into contact with the inner edge forming the housing portion of the fixed housing. Therefore, the maximum displacement amount (distance) of the movable housing in the contact / separation direction with respect to the substrate is determined as a distance obtained by subtracting the length of the protruding portion in the direction from the distance from the substrate to the inner edge of the housing portion.

  However, the distance between the inner edge of the housing portion and the board varies depending on the amount of solder used when mounting the terminal on the board, the degree of warping of the board, the difference in the assembly position of the terminal with respect to the fixed housing or movable housing, etc. It varies greatly depending on factors. Of these, the factors related to the board and mounting are not caused by the connector itself, but are also structural factors that have a large effect on small connectors, so the maximum displacement of the movable housing in the direction of contact with and away from the board There is a risk of large fluctuations in the amount. If the distance between the inner edge of the housing part and the substrate becomes too long, the movable part may be excessively elastically deformed. In such a case, there is a problem that a large burden is applied to the movable part, and when the vibration is repeated, the movable part is likely to be plastically deformed or damaged.

  The present invention has been made against the background of the prior art as described above. The purpose is to provide a connector that is less likely to cause plastic deformation or damage to the movable part even if the movable part is repeatedly elastically deformed in a specific direction.

  In order to achieve the above object, the present invention is configured as follows.

  The present invention includes a fixed housing fixed to a substrate, a movable housing that is held displaceably with respect to the fixed housing and has an insertion port for a connection object, and a contact portion between the connection object and For a connector including a terminal having a movable portion that elastically supports the movable housing so as to be displaceable with respect to the fixed housing, the fixed housing is formed by a plurality of divided housings arranged outside a peripheral wall of the movable housing. A connector is provided.

  The fixed housing is formed by a plurality of divided housings. Therefore, unlike the conventional fixed housing, it is not necessary to insert and assemble the movable housing from the insertion opening facing the substrate. For this reason, the fixed housing can be provided with a restricting portion that stops the displacement of the movable housing before coming into contact with the substrate. That is, it is possible to realize a connector in which the distance from the substrate does not affect the displacement amount of the movable housing. Further, the fixed housing can be a connector that can be assembled to the movable housing from an arbitrary direction.

  More specifically, for example, the fixed housing can be assembled such that each divided housing is brought closer to the side of the peripheral wall of the movable housing. By adopting such a configuration, a restricting portion that stops displacement in the direction approaching the substrate and a restricting portion that stops displacement in the direction away from the substrate are provided at the inner edge of the housing portion of the fixed housing. The divided housings can be combined from the side of the peripheral wall of the movable housing so that the protruding portion provided on the peripheral wall of the movable housing is sandwiched between the restricting portions. Even with such a fixed housing different from the conventional connector, the displacement of the movable housing in the direction approaching the substrate and the direction away from the substrate can be restricted by the inner edge of the fixed housing accommodating portion. Therefore, the displacement of the movable housing in the contact / separation direction with respect to the substrate can be prevented from being changed depending on the distance between the fixed housing and the substrate. In this way, the maximum displacement amount of the movable housing in the contact / separation direction with respect to the board can be easily controlled by the connector structure, so that the movable part is unintentionally elastic in that direction unintentionally due to factors related to the board or mounting. It is possible to avoid the problem of deformation. Thus, by providing the opening in a direction other than the direction in which the maximum displacement amount of the movable housing needs to be reliably controlled, excessive elastic deformation of the movable part in the direction can be suppressed.

  The plurality of divided housings of the present invention can have the same shape.

  By doing so, there is no need to manufacture a plurality of molds, and thus a connector that can be manufactured at a lower cost can be obtained.

  The plurality of divided housings of the present invention can be formed in a frame shape surrounding the peripheral wall of the movable housing.

  As described above, the plurality of divided housings of the present invention can be assembled so as to be close to the side of the peripheral wall of the movable housing. As a specific form, the plurality of split housings are assembled to the peripheral wall of the movable housing. It can be formed in a frame shape surrounding. About this "frame shape", the surrounding wall of a movable housing should just be enclosed from the outer side by the combination of a division | segmentation housing. Specifically, it can be formed by two L-shaped divided housings corresponding to two adjacent sides of the movable housing. Moreover, it can form with the linear division | segmentation housing in alignment with 1 side of a movable housing. Furthermore, a plurality of divided housings can be formed by a combination of these L-shaped and linear divided housings.

  The fixed housing according to the present invention may have a first restricting portion that contacts the movable housing in the insertion direction of the connection object.

  By providing the fixed housing with the first restricting portion that comes into contact with the movable housing in the insertion direction of the connection object, the first housing depends on the amount of solder used when the fixed housing and the terminal are fixed to the substrate. The position of the restricting portion does not fluctuate. Therefore, the maximum displacement amount of the movable housing in the insertion direction can be kept within the tolerance range of the fixed housing and the movable housing.

  Such a 1st control part can be made into the 1st protrusion part provided in the wall part of the said fixed housing.

  By providing the first projecting portion as the wall portion of the fixed housing, the influence on the fluctuation of the maximum displacement amount can be kept within the tolerance range of the resin moldings of the fixed housing and the movable housing.

  The fixed housing of the present invention may have a second restricting portion that contacts the movable housing in the direction in which the connection object is removed.

  By providing the fixed housing with the second restricting portion that comes into contact with the movable housing in the direction in which the connection object is removed, the second amount depends on the amount of solder used when the fixed housing and the terminal are fixed to the substrate. The position of the restricting portion does not fluctuate. Therefore, the maximum displacement amount of the movable housing in the extraction direction can be kept within the tolerance range of the fixed housing and the movable housing.

  Such a 2nd control part can be made into the 2nd protrusion part provided in the wall part of the said fixed housing.

  By providing the second projecting portion as the wall portion of the fixed housing, the influence on the fluctuation of the maximum displacement amount can be kept within the tolerance range of the resin moldings of the fixed housing and the movable housing.

  The fixed housing according to the present invention includes a first restricting portion that comes into contact with the movable housing in the insertion direction of the connection object, and a second restriction portion that makes contact with the movable housing in the removal direction of the connection object. It can have a regulation part.

  According to the present invention, the positions of both the first restricting portion and the second restricting portion provided on the fixed housing vary depending on the amount of solder used when the fixed housing and the terminal are fixed to the substrate. There is nothing to do. Therefore, the maximum displacement amount of the movable housing can be kept within the tolerance range of the fixed housing and the movable housing in both the insertion direction and the removal direction of the connection object. And the 1st control part and the 2nd control part can be constituted as the 1st projection part and the 2nd projection part which are provided in the wall part of the fixed housing in the above-mentioned present invention.

  In the movable part of the present invention, the load that elastically deforms in at least one of the insertion direction and the removal direction of the connection object to the fixed housing is normal in at least one of the contact part and the connection object. The load can be smaller than the load displaced in the insertion / extraction direction from the contact position.

  By carrying out like this, when a connection target object displaces with respect to a contact part in the insertion / extraction direction or the extraction direction, a movable part elastically deforms before position-shifting with respect to a contact part. Therefore, it is possible to reliably continue the conductive contact at the regular contact position without causing the connection object to be displaced with respect to the contact portion. Therefore, even when vibration along the insertion / extraction direction of the connection object is repeatedly applied to the connector, the occurrence of plating peeling at the contact portion of the terminal can be suppressed, so that connection reliability can be maintained.

  ADVANTAGE OF THE INVENTION According to this invention, even if a movable part repeats elastic deformation in a specific direction, it can be set as the connector which does not produce the situation of causing a plastic deformation or damage to a movable part.

  The terminal insertion portion 4e is provided at the lower end of the movable housing 4 so as to communicate with the fitting chamber 4b. A contact portion 5e of the terminal 5 to be described later is inserted into the fitting chamber 4b from the terminal insertion portion 4e.

(Terminal)
The terminal 5 is formed by punching a conductive metal plate and bending it. As shown in FIG. 8, the terminal 5 includes a board connecting portion 5a, a housing fixing portion 5b, a movable portion 5c, a base end portion 5d, and a contact portion 5e.

  The board connecting part 5 a is disposed on one end side of the terminal 5. By soldering the board connecting portion 5a to the board C, the terminals 5 are electrically connected to a circuit pattern (not shown) provided on the board C.

  The housing fixing portion 5b is connected to the board connecting portion 5a, and projecting portions 5b1 that are engaged with and fixed to the fixing housing 3 are formed on both ends in the width direction X.

  The movable part 5c is connected to the housing fixing part 5b and is a thin-shaft spring piece having a substantially U shape. The movable portion 5c can be elastically deformed in any of the width direction X, the front-rear direction Y, and the height direction Z.

  The base end portion 5d is connected to the movable portion 5c and extends along the height direction Z. On both ends of the base end portion 5d in the width direction X, projecting portions 5d1 that engage with the inner wall of the fitting chamber 4b of the movable housing 4 are formed.

The two contact portions 5e2 are in conductive contact with the mating terminal 2a of the mating connector 2 so as to be sandwiched from both sides in the front-rear direction Y.

[Description of assembly method]
As shown in FIG. 9 and FIG. 10, the first divided housing 6 and the second divided housing 7 of the fixed housing 3 are sandwiched with respect to the movable housing 4 in the width direction X and the front-rear direction Y, and the outer periphery is the side surface. Move so that it surrounds. Then, the first locking portion 4 c of the movable housing 4 is accommodated in the accommodating portion 6 c of the first divided housing 6, and the second locking portion 4 d is accommodated in the accommodating portion 7 c of the second divided housing 7.

  Subsequently, the terminal 5 is fixed to the movable housing 4. Specifically, as shown in FIG. 11, the contact portion 5 e of the terminal 5 is inserted from the terminal insertion portion 4 e provided on the bottom surface side of the movable housing 4. And the base part 5d is fixed inside the fitting chamber 4b by making the protrusion 5d1 provided in the base end part 5d engage with the inner wall of the fitting chamber 4b. Thus, when the contact portion 5e and the base end portion 5d are inserted into the fitting chamber 4b, the movable housing 4 is displaced so as to be lifted upward by the base end portion 5d. The first locking portion 4c of the lifted movable housing 4 is in contact with the upper protruding portion 6b3 of the first divided housing 6 so that the upward displacement is restricted, and the second locking portion of the movable housing 4 is controlled. 4d abuts on the upper projecting portion 7b3 of the second divided housing 7 so that upward displacement is restricted. Thus, the upward displacement of the movable housing 4 is stopped, and the base end portion 5d is press-fitted into the fitting chamber 4b. Thus, the fixing of the contact portion 5e and the base end portion 5d of the terminal 5 to the movable housing 4 is completed.

  Thereafter, the housing fixing portion 5 b of the terminal 5 is fixed to the fixed housing 3. Specifically, the housing fixing portion 5 b of the terminal 5 fixed to the front fitting chamber 4 b in the front-rear direction Y of the movable housing 4 is press-fitted into the fixing groove 6 a 1 of the first divided housing 6. As a result, the protrusion 5b1 of the housing fixing portion 5b is engaged with and fixed to the inner wall of the fixing groove 6a1. Similarly, the housing fixing portion 5 b of the terminal 5 fixed to the rear fitting chamber 4 b in the front-rear direction Y of the movable housing 4 is press-fitted into the fixing groove 7 a 1 of the second divided housing 7. As a result, the protrusion 5b1 of the housing fixing portion 5b is engaged with and fixed to the inner wall of the fixing groove 7a1. Thus, the fixing of the housing fixing portions 5b of all the terminals 5 to the fixed housing 3 is completed. Thus, the assembly of the connector 1 is completed.

  In this state, the first divided housing 6 and the second divided housing 7 are not directly fixed to each other, and one terminal 5 and the movable housing 4 in the front-rear direction Y are interposed via the other terminal 5. It is in a connected state. Therefore, the distance and positional relationship between the first divided housing 6 and the second divided housing 7 can be changed by elastically deforming the movable portion 5c of the terminal 5 in a state where the connector 1 is not mounted on the substrate C. is there. Only when the connector 1 is mounted on the substrate C, the distance and positional relationship between the first divided housing 6 and the second divided housing 7 are determined.

  As an assembly sequence, first, the first locking portion 4c of the movable housing 4 is accommodated and positioned in the accommodating portion 6c of the first divided housing 6, and subsequently, the accommodating portion 7c of the second divided housing 7 is accommodated. In the example, the second locking portion 4d of the movable housing 4 is accommodated and positioned, and finally the terminal 5 is fixed to the housings 4, 6, and 7. However, the order is not limited to this. For example, first, the positioning of the movable housing 4 with respect to the first divided housing 6 is first performed, and after the terminal 5 is fixed to each of the housings 4 and 6, the positioning of the movable housing 4 with respect to the second divided housing 7 is performed, Finally, the terminal 5 may be fixed to each of the housings 4 and 7.

[Explanation of usage]
The mating terminal 2 a of the mating connector 2 is inserted into the fitting chamber 4 b from the insertion port 4 a of the movable housing 4 and is brought into contact with the contact portion 5 e of the terminal 5. The mating terminal 2a widens the gap between the contact portions 5e2. At this time, the movable portion 5c is elastically deformed by the pressing of the mating terminal 2a against the contact portion 5e, and the movable housing 4 is directed toward the substrate C. Displace. The first locking portion 4c of the movable housing 4 is in contact with the lower protruding portion 6b4 of the first divided housing 6 so that the downward displacement is restricted. Moreover, the 1st latching | locking part 4c of the movable housing 4 contact | abuts to the lower side protrusion part 7b4 of the 2nd division | segmentation housing 7, and the downward displacement is controlled. Thus, in a state where the downward displacement of the movable housing 4 is regulated, the mating terminal 2a further expands the gap between the contact portions 5e2, and the mating terminal 2a is inserted therebetween. At that time, the contact portion 5e2 and the counterpart terminal 2a are displaced from each other. Thereafter, the mating terminal 2a is stopped from being inserted into the mating chamber 5d, and the mating operation is performed while the mating terminal 2a is in conductive contact with the contact portion 5e2 of the terminal 5 at the regular contact position P1. Complete (see FIG. 14).

  In the movable housing 4, the first locking portion 4 c is housed in the housing portion 6 c of the first split housing 6, and the second locking portion 4 d is housed in the housing portion 7 c of the second split housing 7. Thus, the displacement along the width direction X is restricted by the restriction plate portion 6b2 of the first divided housing 6 and the restriction plate portion 7b2 of the second divided housing 7. In a state where the connector 1 is mounted on the substrate C, the interval between the restriction plate portion 6b2 and the restriction plate portion 7b2 is the distance between the tip end portion 4c1 of the first locking portion 4c and the second locking portion 4d of the movable housing 4. It is formed longer than the distance of the tip portion 4d1. Therefore, movable gaps S1 and S1 ′ are formed between the first locking portion 4c and the restriction plate portion 6b2 and between the second locking portion 4d and the restriction plate portion 7b2 (see FIG. 12). . Therefore, the movable housing 4 is elastically displaced along the width direction X within the movable gaps S1 and S1 '.

  Further, the length L1 in the front-rear direction Y of the accommodating portion 6c of the first divided housing 6 is formed to be longer than the length in the front-rear direction Y of the first locking portion 4c of the movable housing 4. Therefore, a movable gap S2 along the front-rear direction Y is formed between the first locking portion 4c and the inner wall 6c1 that forms the accommodating portion 6c (see FIG. 15). Therefore, the 1st latching | locking part 4c can be displaced along the front-back direction Y inside the movable gap S2. Similarly, the length L1 'in the front-rear direction Y of the accommodating portion 7c of the second divided housing 7 is formed longer than the length in the front-rear direction Y of the second locking portion 4d of the movable housing 4. Therefore, a movable gap S2 'along the front-rear direction Y is formed between the second locking portion 4d and the inner wall 7c1 that forms the accommodating portion 7c (see FIG. 15). Therefore, the second locking portion 4d is also elastically displaced along the front-rear direction Y within the movable gap S2 '.

  Further, the distance L2 between the upper protruding portion 6b3 and the lower protruding portion 6b4 of the first divided housing 6 is formed longer than the length in the height direction Z of the second locking portion 4d of the movable housing 4. . Therefore, a second movable gap S4 is formed between the first locking portion 4c and the upper protruding portion 6b3, and the first locking portion 4c and the lower protruding portion 6b4 are provided with the first moving gap S4. A movable gap S3 is formed (see FIG. 13). Therefore, the first locking portion 4c can be displaced along the height direction Z within the movable gaps S3 and S4. Similarly, the distance (not shown) between the upper protruding portion 7b3 and the lower protruding portion 7b4 of the second divided housing 7 is longer than the length of the second locking portion 4d of the movable housing 4 in the height direction Z. It is formed long. Therefore, a second movable gap (not shown) having the same length as the second movable gap S4 is formed between the second locking portion 4d and the upper protruding portion 7b3. A first movable gap (not shown) having the same length as the first movable gap S3 is formed between 4d and the lower protrusion 7b4. Therefore, the second locking portion 4d can also be displaced along the height direction Z within each movable gap.

  Since the upper protruding portion 6b3 and the lower protruding portion 6b4 are provided as a part of the first divided housing 6 made of a single insulating resin, the distance L2 (FIG. 13) along the height direction Z is within a tolerance range. It is constant at. Further, since the upper protruding portion 7b3 and the lower protruding portion 7b4 are also provided as a part of the second divided housing 7 made of a single insulating resin, the distance L2 ′ along the height direction Z is also within the tolerance range. Is constant within.

  Therefore, the intervals L2 and L2 ′ that determine the amount of displacement along the height direction Z of the movable housing 4 are factors related to the substrate and mounting, for example, use of solder used when the fixed housing 3 is soldered to the substrate C. The situation where the amount of warpage or the warpage of the substrate C, the fixed grooves 6a1 and 7a1 of the fixed housing 3, the press-fitting amount of the terminal 5 into the fitting chamber 5d of the movable housing 4, the fixed position, etc. does not occur. Therefore, the fluctuation of the maximum displacement amount in the height direction Z of the movable housing 4 with respect to the fixed housing 3 can be suppressed within the tolerance range of the connector 1. Therefore, like the conventional connector, considering the factors related to unexpected board and mounting, it is estimated that the maximum displacement of the movable housing greatly fluctuates beyond the tolerance of the connector itself, and the movable gap (S3, S3 ') Need not be provided larger than necessary, and can contribute to miniaturization of the connector 1 itself. In addition, since the fluctuation of the maximum displacement amount of the movable housing can be suppressed within the tolerance of the connector 1 itself, the movable portion 5c is elastically deformed excessively repeatedly, so that the movable portion 5c is plastically deformed or damaged. It can be made difficult to happen.

  Further, for the movable portion 5c of the terminal 5, a load that elastically deforms the mating terminal 2a of the mating connector 2 in the insertion direction and the withdrawal direction (the height direction Z in the present embodiment) of the mating connector 2 is applied to the contact portion 5e and the mating terminal 2a. Is set smaller than the load that is displaced in the insertion / extraction direction from the normal contact position P1. Therefore, when the mating terminal 2a is displaced with respect to the contact portion 5e in the insertion / extraction direction or the removal direction, the movable portion 5c is elastically deformed before being displaced with respect to the contact portion 5e. Accordingly, the mating terminal 2a can be reliably kept in conductive contact at the regular contact position P1 without being displaced with respect to the contact portion 5e. Therefore, even if the vibration along the insertion / extraction direction of the mating terminal 2 a is repeatedly applied to the connector 1, it is possible to suppress the occurrence of peeling of the plating of the contact portion 5 e of the terminal 5. Therefore, the connector 1 with high connection reliability can be obtained.

The example in which 7c is provided on the side wall 7b of the second divided housing 7 is shown. On the other hand, the front wall 6a of the first divided housing 6 has an accommodating chamber for accommodating the first locking portion 4c and the second locking portion 4d, or the rear surface of the second divided housing 7. The wall 7a may have.

Can do. Specifically, as an example, the movable housing 4 can be formed as a pair of linear divided housings surrounding the outside along the longitudinal side.
