Description

  The present invention relates to a rear holder that is attached to a wire lead-out portion of a connector housing that houses connector terminals.

  2. Description of the Related Art A connector structure including a rear holder that is attached to the back of a connector housing that houses connector terminals connected to the ends of the wires (the side from which the wires are drawn out from the connector housing) is known (see Patent Document 1). The rear holder closes the opening of the wire lead-out portion of the connector housing and holds the electric wire so that a force applied when the electric wire is bent does not reach the inside of the connector housing. And if it is a waterproof connector as disclosed by patent document 1, drop-off prevention of sealing members, such as a rubber plug attached to the circumference | surroundings of an electric wire, will be achieved with a rear holder. In contrast, in the case of a non-waterproof connector, it is not necessary to attach a sealing member around the electric wire, but foreign matter (for example, a wire) to the inside of the connector housing (especially the live area where the connector terminal is electrically connected to the connection partner terminal). And countermeasures for preventing the rear holder from invading with a rear holder.

JP 2011-54393 A

  Such a rear holder has a cylindrical wire holding portion for holding the electric wire drawn out from the connector housing, and when the rear holder prevents foreign matter from entering, the assumed foreign matter is the largest gap between the wire holding portion and the outer periphery of the wire. The diameter dimension of the electric wire holding part is set so as not to pass through (hereinafter referred to as an allowable gap). In addition, the rear holder is composed of two parts as a whole including the wire holding part in consideration of workability at the time of mounting to the connector housing, and the deterioration of portability due to the increase in the number of parts and the complexity of parts management are reduced. In order to prevent this, a divided structure (connected structure) in which these divided bodies are connected may be used (see Patent Document 1).

  In the rear holder split structure disclosed in Patent Document 1, two split bodies are connected to each other by a connecting portion (hinge) so as to be able to rotate with each other. After clamping, the rear holder is attached to the connector housing by advancing these divided bodies and pushing them into the wire lead-out portion. However, when such a mounting method is used with a non-waterproof connector that prevents intrusion of foreign matter with a rear holder, the following problems may occur.

  In this case, for example, in order to surely prevent the entry of foreign matters such as a fine wire or a metal wire, it is necessary to prevent a gap from being generated between the electric wire holding portion and the outer peripheral portion of the electric wire. For this reason, it is necessary to pinch the electric wire between the two divided bodies and tighten them tightly, and when these divided bodies are advanced to the wire lead-out portion along the electric wire, the friction between the divided body (electric wire holding portion) and the outer peripheral portion of the electric wire As a result, the load on the rear holder is deteriorated.

  The present invention has been made based on this, and the problem to be solved is to improve the mounting workability of the rear holder having a split structure in which the split bodies are connected by the connecting portion.

  In order to solve the above-mentioned problems, a rear holder according to the present invention is attached to an electric wire extraction portion of a connector housing that accommodates a connector terminal connected to an end of an electric wire, and has a cylindrical shape that holds an electric wire drawn from the electric wire extraction portion. An electric wire holding portion; and a crowned portion that surrounds the electric wire holding portion and is crowned by an opening of the electric wire lead-out portion, wherein the electric wire holding portion and the crowned portion are formed of the electric wire holding portion. It is configured as two divided bodies along the cylinder axis direction, and is formed by connecting the two divided bodies with a band-shaped connecting portion. The crown portion of the other divided body is formed to have a length that can be crowned to the opening of the wire lead-out portion in a state where the crown is covered with the opening of the portion.

  According to this, even when two divided bodies are connected by the connecting portion, the crowned portion of one divided body is first crowned prior to the opening of the wire lead-out portion, and then the other divided body The crown portion can be crowned to the opening of the wire lead-out portion. Thus, even if it is a structure where a rear holder is mounted by pushing the crowned portion into the opening of the electric wire lead-out portion by crowning the crowned portions of the two divided bodies one by one, The pushing force (that is, the force required for mounting the rear holder) can be reduced as compared with the case where the crown portions of the two divided bodies are simultaneously crowned.

  In this case, by forming the wire holding portion so as to have a portion accommodated in the wire lead-out portion, the housing portion can be brought into contact with the wire lead-out portion after the rear holder is mounted. It can prevent that an electric wire holding part opens so that it may mutually space apart. Further, as an example of a structure in which the crowned portion is crowned on the wire lead-out portion, a recess for accommodating the opening of the wire lead-out portion is formed in the crowned portion on the outer peripheral side of the wire holding portion. Can do. Accordingly, if the opening of the wire lead-out portion is accommodated in the recess, the crowned portion can be crowned in the opening.

  The connecting portion may be configured to connect the two divided bodies by inclining a band axis in the width direction on the back side of the crowned portion of the crowned portion to the opening of the wire lead-out portion. Moreover, the said connection part can also be set as the structure which bend | folds so that an intermediate part may protrude with respect to a strip | belt-thickness direction rather than the connection end part with the said two division bodies, and connects the said 2 division bodies. Thus, when the crown portion of one divided body is preceded by the opening of the wire lead-out portion, when twisting power is applied to the connecting portion via the other divided body around the inclined band axis, Can be positioned on the front side of the crown portion in the crown direction so as to be separated from one of the divided bodies. For this reason, when the crown part of one divided body is crowned to the opening of the wire lead-out part, a space on the back side in the crown direction of the other divided body (side of the one divided body) can be made. It is possible to prevent one divided body from contacting (interfering) with the other divided body during the operation. As a result, it is possible to smoothly perform the crowning operation of the crowned portion, and consequently the mounting operation of the rear holder.

  According to the present invention, it is possible to improve the mounting workability of the rear holder having a split structure in which the split bodies are connected by the connecting portion.

  Hereinafter, a rear holder according to an embodiment of the present invention will be described with reference to the accompanying drawings. The rear holder is a member that is attached to the wire lead-out portion of the connector housing that accommodates the connector terminal connected to the terminal of the wire. In this embodiment, in addition to holding the wire drawn from the wire lead-out portion, It is installed for the purpose of preventing foreign matter from entering inside. In the present embodiment, for example, a connector used in a high-voltage electric system in an electric vehicle, a hybrid vehicle, or the like, such as a wire or a metal wire (metal thin wire) in a non-waterproof connector that does not have a sealing member such as a rubber plug. Although the case where a rear holder is used in order to prevent intrusion of foreign matter is assumed, the use is not limited to this.

  1-3, the structure of the rear holder 2 which concerns on this embodiment is shown. FIG. 1 is a perspective view showing a state in which the rear holder 2 is mounted on the wire lead-out portion 11 of the connector housing 10. FIG. 2 is a perspective view showing a state before the rear holder 2 is attached to the wire lead-out portion 11, and FIG. 3 is a perspective view showing a state after the rear holder 2 is attached to the wire lead-out portion 11 (rear holder alone). In the following description, the arrow X direction shown in FIG. 1 is the left-right direction, the arrow Y direction is the front-rear direction, and the arrow Z direction is the up-down direction. Among these, in the front-rear direction, the arrow Y1 direction in FIG. 1 is the front side (front), and the arrow Y2 direction is the rear side (rear). However, the left-right direction, the front-rear direction, and the up-down direction do not necessarily match the actual directions at the time of implementation.

  As shown in FIGS. 1 to 3, the rear holder 2 is formed so as to surround the wire holding portion 3 and the cylindrical wire holding portion 3 that holds the wire drawn from the wire drawing portion 11 of the connector housing 10. And a crowned portion 4 to be crowned by an opening 12 (see FIG. 5) of the portion 11. The wire lead-out portion 11 of the connector housing 10 is opened rearward (see FIG. 5), and a connector terminal (not shown) connected to the end of the wire is accommodated in the connector housing 10 from the opening 12. . And the electric wire connected to the accommodated connector terminal is pulled out rearward from the electric wire extraction part 11 via the rear holder 2. On the other hand, the front of the connector housing 10 is opened so that the connector terminal faces the connection counterpart terminal, and the terminals are electrically connected.

  The electric wire holding part 3 and the crowned part 4 are divided into two divided bodies 5 (appropriately, the electric wire holding parts 3a and 3b and the crowned parts 4a and 4b, divided parts) along the cylinder axis direction (front-rear direction) of the electric wire holding part 3. 5a and 5b), and the two divided bodies 5 are connected by a belt-like connecting portion (hereinafter referred to as a hinge) 6.

  The electric wire holding part 3 of the two divided bodies 5 has a concave curved surface 31 along the outer peripheral portion of the electric wire, and is arranged with the concave curved surfaces 31 facing each other. When the crowned portion 4 is crowned in the opening 12 of the wire lead-out portion 11, a cylindrical cavity (hereinafter referred to as a wire holding space) is formed between the opposing concave curved surfaces 31, and is pulled out from the wire lead-out portion 11 to the outside. The electric wire is held in the electric wire holding space. The electric wire holding part 3 is formed so as to have a part accommodated in the electric wire drawing part 11. In the present embodiment, the front portion of the wire holding portion 3 corresponding to the back side with respect to the crowned direction of the crowned portion 4 to the opening 12 of the wire lead-out portion 11 (the front side of the bottom portion 40 of the crowned portion 4 described later). (Positioned part) 32 is accommodated in the wire lead-out part 11. On the other hand, the rear portion (the portion located on the rear side of the bottom portion 40) 33 corresponding to the front side with respect to the crowned direction is not accommodated in the wire lead-out portion 11, and the crowned portion 4 It is exposed from the (bottom 40) to the outside. The electric wire holding space (the front side portion of the electric wire holding portion 3) communicates with the cylindrical portion 13 (see FIG. 5) formed in the electric wire drawing portion 11.

  For example, if the radius of curvature of the concave curved surface 31 of the electric wire holding part 3 is set with the minimum radius dimension within the tolerance range of the electric wire as a target value, the concave curved surface 31 of the electric wire holding space within the tolerance range of the electric wire is formed. It is possible to reliably contact the outer peripheral portion, and it is possible to reliably prevent a wire or the like assumed as a foreign object from slipping between the concave curved surface 31 and the outer peripheral portion of the electric wire. However, even if the concave curved surface 31 is not in contact with the outer peripheral portion of the electric wire, the gap between the concave curved surface 31 and the outer peripheral portion of the electric wire is set as long as the maximum gap between them is set to be smaller than at least the diameter dimension of the wire or the like. It is possible to prevent the metal wire from slipping through. For example, even if the wire is bent or bent when the wire is routed or vibrated, if the maximum gap that occurs is set smaller than the diameter of the wire, the wire Etc. can be prevented from slipping through.

  The crowned portion 4 is adapted to be crowned by the opening 12 of the wire lead-out portion 11 from the cylinder axis direction (front-rear direction) of the wire holding portion 3, and the bottom portion 40 through which the wire holding portion 3 penetrates the center, An upper wall 41, a side wall 42, and a lower wall 43 erected from the bottom 40 are provided so as to surround the outer peripheral side of the electric wire holding unit 3. Among these, the bottom 40, the upper wall 41, and the lower wall 43 are each divided into two divided bodies 5. Surrounded by these walls 41, 42, 43, the crowned portion 4 is formed with a recess 44 for accommodating the opening 12 of the wire lead-out portion 11 on the outer peripheral side of the wire holding portion 3. Thus, the crowned portion 4 is crowned by the opening 12 by pushing the crowned portion 4 forward so as to accommodate the opening 12 of the wire lead-out portion 11 in the recess 44. In this embodiment, the end of the wire lead-out portion 11 on the opening 12 side is fitted in the recess 44, and the crowned portion 4 is covered so that the upper wall 41, the side wall 42, and the lower wall 43 cover the outer periphery of the end portion. It is crowned.

  The crowned crowned portion 4 is configured such that the locking portion (locking claw) 16 of the wire lead-out portion 11 is engaged with the locked portion (locking hole) 45 of the side wall 42 at the time of crowning. The stopper from the drawer part 11 is intended. The locked portion (locking hole) 45 opens to an elastic arm 46 provided between two notches formed in the side wall 42. 1 and 5 show the locking portion (locking claw) 16 only on one side, but on the other side corresponding to the locked portion (locking hole) 45 of the pair of side walls 42. Are also formed with similar locking portions (locking claws). In this way, the crowned portion 4 is crowned and the locked portion 45 is engaged, so that the rear holder 2 is in a state of being mounted on the wire lead-out portion 11.

  In the present embodiment, when the rear holder 2 is mounted, the front side portion 32 of the wire holding portion 3 is accommodated inside the wire drawing portion 11, and the front side portion 32 is connected to the peripheral wall 14 (see FIG. 5) of the wire drawing portion 11. Get in touch. Accordingly, the peripheral wall 14 of the wire lead-out portion 11 prevents the electric wire holding portions 3a, 3b of the two divided bodies 5a, 5b from opening in the left-right direction so as to be separated from each other. In addition, if it is set as the structure which can insert the protrusion 34 provided in the front side part of the electric wire holding part 3 along the front-back direction in the guide groove 15 (refer FIG. 5) formed in the inner side of the surrounding wall 14, it will be an electric wire extraction part. It is possible to stabilize the posture of the rear holder 2 at the time of attachment to the motor 11.

  The hinge 6 is integrally formed of the same material (for example, a resin material) as the two divided bodies 5, and these divided bodies 5 are connected so as not to be separated. Thereby, the fall of the portability of rear holder 2 and complication of parts management are prevented. The hinge 6 is configured such that the crowned portion 4a of one divided body 5 (for example, the divided body 5a) is covered with the opening 12 of the wire lead-out portion 11, and the other divided body 5 (for example, the divided body 5b) is covered. The crowned portion 4 b is formed to have a length that can be crowned in the opening 12 of the wire lead-out portion 11. Thereby, even if it is a case where the two division bodies 5a and 5b are connected by the hinge 6, the crown part 4a of one division body 5a is first crowned ahead of the opening 12 of the wire lead-out part 11, and thereafter The crown portion 4b of the other divided body 5b can be crowned by the opening 12 of the wire lead-out portion 11. In this way, the crowned portions 4a and 4b of the two divided bodies 5a and 5b are crowned one by one, so that the forward pushing force at that time (the opening side end of the wire lead-out portion 11 to the recess 44) Fitting force) can be reduced as compared with the case where the crowned portions 4a and 4b are crowned simultaneously. And since the two division bodies 5 are connected by the hinge 6 so that such a crowning operation | work of each one is possible, this division body is not interrupted without obstructing the crowning operation | work of the one preceding division body 5a. Since the other divided body 5b can be positioned in the vicinity of 5a in a state where the subsequent crowning work is possible, work efficiency is high and workability can be improved.

  Further, when the crowned portion 4b is crowned on the opening 12 of the wire lead-out portion 11 with a delay from the crowned portion 4a, the electric wire holding space can be formed with the concave curved surfaces 31 facing each other. From the front of the wire lead-out part 11 of the connector housing 10, the electric wire is clamped between the wire holding parts 3a and 3b of the two divided bodies 5a and 5b in advance, and then the divided bodies 5a and 5b are advanced to be crowned. It is not necessary for the portions 4a and 4b to be crowned (pushed) into the opening 12 of the wire lead portion 11 at the same time. Therefore, for example, the gap between the concave curved surface 31 and the outer peripheral portion of the electric wire is eliminated and the concave curved surface 31 and the outer peripheral portion of the electric wire are brought into contact with each other in order to prevent the entry of an extremely thin wire having an IP code protection grade of about class 4 (electric wire diameter 1 mm). Or the maximum gap can be made extremely small, and even in such a state, the load applied to the outer periphery of the electric wire during the mounting operation of the rear holder 2 can be suppressed. That is, since it is not necessary to tighten the electric wire excessively during the mounting operation, it is possible to improve the mounting workability of the rear holder 2 and to prevent the electric wire from being damaged during the mounting operation.

  Next, a specific configuration of the hinge 6 according to the present embodiment will be described. The hinge 6 is formed in an elastically deformable band shape, and is connected to the two divided bodies 5 at both ends (hereinafter referred to as connecting ends) 61 in the longitudinal direction as shown in FIGS. The connecting end portions 61 are connected by an intermediate portion 62 that is a part. Each connecting end portion 61 is connected to the rear upper end portion of the split body 5 on the front side of the longitudinal side surface of the hinge 6 (corresponding to the front upper end portion in the crown direction of the crown portion 4 with respect to the wire lead-out portion 11). And protrudes rearward from the divided body 5. In other words, each connection end portion 61 is connected to the rear portion of the upper wall 41 and protrudes rearward from the bottom portion 40. Thereby, the two division bodies 5 can be moved mutually via the hinge 6, and a mutual movable range is a front side rather than a rear side (equivalent to the crown direction back side of the crown part 4 with respect to the electric wire extraction part 11). It can be taken with a big.

  As shown in FIG. 4, the hinge 6 has a band axis in the width direction (as an example, as shown in FIG. 4B) on the inner side of the crowned portion 4 to the opening 12 of the wire lead-out portion 11. The two divided bodies 5 are connected by tilting the axis S1). In the present embodiment, the hinge 6 has a predetermined angle (an axis S1 shown in FIG. 4B) with respect to a straight axis (an axis S2 as shown in FIG. 4B, for example). It is in a state of being tilted forward at an angle θ) between the axes S2, and the rear side is positioned higher than the front side of the hinge 6 itself.

  In addition, the hinge 6 is bent so that the intermediate portion 62 protrudes in the thickness direction from the connecting end portion 61 with the two divided bodies 5, thereby connecting the two divided bodies 5. In the present embodiment, the hinge 6 is configured such that the intermediate portion 62 protrudes by bending upward. As a result, the hinge 6 is elastically deformed so that the positions of both the connecting end portions 61 are changed with the protruding portion of the intermediate portion 62 as a fulcrum. In this case, the hinge 6 (intermediate portion 62) is curved and protrudes upward in any state before the rear holder 2 shown in FIG. 2 is attached to the wire lead-out portion 11 and after the attachment shown in FIG. 3. The hinge 6 is elastically deformed with the state (the state shown in FIG. 2) before the rear holder 2 is attached to the wire lead-out portion 11 as a steady state.

  Therefore, when the crowned portion 4 of one split body 5 (as an example, split body 5a) is crowned on the opening 12 of the wire lead-out portion 11 in advance, the other split body 5 (as an example) from the state shown in FIG. For example, when twisting power is applied to the hinge 6 via the divided body 5b around the inclined band axis so that the divided body 5b) is separated from the divided body 5a, the hinge 6 causes the divided body 5b to move relative to the divided body 5a. It is elastically deformed so as to be positioned at the upper rear side. In other words, it is easy to restrict the deformation of the hinge 6 in a direction other than the deformation direction. Accordingly, when the crowned portion 4a of the divided body 5a is crowned on the opening 12 of the wire lead-out portion 11, there is a space on the front side of the divided body 5b (that is, a space on the side of the divided body 5a), and the work is in progress. It is possible to prevent the divided body 5a from contacting (interfering) with the divided body 5b. For this reason, the concave curved surface 31 of the electric wire holding part 3a of the divided body 5a is made to follow the outer peripheral part of the electric wire, and the operation of pushing the crowned part 4a forward to cover the opening 12 of the electric wire drawing part 11 is smoothly performed. be able to.

  After the crowned portion 4a of the divided body 5a is crowned, when the crowned portion 4b of the divided body 5b is crowned with a delay, the divided body 5b can be easily moved downward by the elastic return deformation of the hinge 6 (the original lower side). (Direction to return to the state). Then, in order to keep the concave curved surface 31 along the outer periphery of the electric wire, the electric wire holding portion 3b of the divided body 5b is rotated from the upper rear side so that the concave curved surface 31 faces the concave curved surface 31 of the electric wire holding portion 3a. The crown portion 4b is pushed forward so that the opening 12 of the wire lead-out portion 11 is crowned. As a result, compared to the case where the crowned portions 4a and 4b of the two divided bodies 5a and 5b are simultaneously crowned, the sliding contact area between the wire holding portion 3 and the wire outer peripheral portion at the time of work can be halved. The pushing force to the front of the divided bodies 5a and 5b (corresponding to the force for fitting the opening 12 side end of the wire lead-out portion 11 into the recess 44) can be reduced. Further, the pushing force to the front for engaging the locked portion (locking hole) 45 of the side wall 42 with the locking portion (locking claw) 16 of the wire lead-out portion 11 (the elastic arm of the side wall 42 is elastically deformed). Can also be reduced in the same manner.

  Thus, according to the rear holder 2 according to the present embodiment, the hinge 6 is formed with a length that allows the crowned portions 4 of the two divided bodies 5 to be crowned one by one to the opening 12 of the wire lead-out portion 11. Thereby, the workability of mounting to the wire lead-out portion 11 can be improved. Moreover, the mounting workability | operativity of the rear holder 2 can be improved further by making the hinge 6 incline and bend | fold like this embodiment.

  Here, in the state after the rear holder 2 is mounted as shown in FIG. 3, the electric wire holding portions 3a, 3b of the two divided bodies 5a, 5b are in contact with each other at the upper end and the lower end, respectively. The lower walls 43 of the crowned portions 4a and 4b are in contact with each other along the front-rear direction, but the upper walls 41 are opposed (separated) along the front-rear direction without contacting each other. And the contact surface of the lower end of the electric wire holding | maintenance part 3a, 3b and the contact surface of the lower wall 43 of the crowned part 4a, 4b are flush | level along the front-back direction. For this reason, after mounting the rear holder 2, a force that causes the two divided bodies 5 a and 5 b to approach each other in the left-right direction (for example, acts from the peripheral wall 14 of the wire lead-out portion 11 through the protrusion 34 of the wire holding portion 3. Can be made to act positively to bring the electric wire holding portions 3a, 3b into contact with each other, not with the crowned portions 4a, 4b having a non-contact portion in part (the upper wall 41). Accordingly, the concave surfaces 31 of the electric wire holding portions 3a and 3b are opposed to each other, and an electric wire holding space is reliably formed between them, and a gap between the concave surface 31 and the outer peripheral portion of the electric wire can be eliminated.

  Although the present invention has been described based on one embodiment as shown in FIGS. 1 to 5, the above-described embodiment is merely an example of the present invention, and the present invention is only the configuration of the above-described embodiment. It is not limited to. Therefore, it is obvious to those skilled in the art that the present invention can be implemented in a form modified or changed within the scope of the gist of the present invention. It goes without saying that it belongs to the claims.

  In the present embodiment described above, the hinge 6 is configured such that the connecting end portion 61 is connected to the divided body 5 at the rear upper end of the divided body 5 (the rear portion of the upper wall 41). You may change in the range used as the back of the intermediate position of the length of the wall 41 in the front-back direction. Even if it changes in this way, it becomes possible to take the mutual movable range of the two division bodies 5 larger on the front side (the front side of the crowned portion 4 in the defendant direction) than the rear side. Moreover, the same effect is acquired also as a structure which connected the connection end part of the hinge with this division body by the rear side lower end part (rear part of a lower wall) of a division body. In this case, the band axis in the width direction of the hinge may be tilted rearward at a predetermined angle with respect to the linear axis along the front-rear direction so that the rear side is positioned below the front side of the hinge itself.

  In the above-described embodiment, the intermediate portion 62 is curved so that the hinge configuration protrudes upward from the connecting end portion 61. For example, the end portions on both sides in the longitudinal direction are erected upward and between the erected ends. The hinges may be protruded upward by connecting them at the intermediate part, or the hinges may be protruded upward by forming the intermediate part in the longitudinal direction so that the cross-sectional shape is substantially inverted V-shaped.
