Description

[Technical field]

[0001] The present invention relates to a female connector having a female terminal. [Background technology]

[0002] 2. Description of the Related Art A female connector is known that includes a female terminal connected to an end of an electric wire and a female housing made of synthetic resin that houses the female terminal.

[0003] For example, the female connector disclosed in Patent Document 1 has a female housing provided with a terminal accommodating chamber that accommodates a female terminal, and a locking lance that locks with the female terminal to prevent the female terminal from coming out. The terminal accommodating chamber opens in two directions, the front and rear sides of the female housing, and the female terminal is inserted into the terminal accommodating chamber from the rear side and assembled. The female connector is mated with a male connector having a male terminal. When mated, the male terminal is inserted into the terminal accommodating chamber from the front side of the female housing and mated with the female terminal. In addition, the female connector is structured such that it is not possible to visually check from the outside whether or not a terminal is partially inserted due to insufficient insertion of the female terminal during manufacturing, and it is necessary to insert a dedicated jig into the female housing to check.

[0010] A "female connector" according to one embodiment of the present invention will be described with reference to Figures 1 to 20. As shown in Figures 1 to 3, a female connector 1 is adapted to be fitted with a male connector 2 which is a mating connector.

[0011] The male connector 2 comprises multiple (5 poles in this example) male terminals 8 connected to the ends of electric wires 12, a male housing 6 that accommodates the multiple male terminals 8, and a spacer 7 that is attached to the male housing 6 to prevent the male terminals 8 from coming loose.

[0012] The electric wire 12 is a coated electric wire in which a conductive core wire 12a is coated with an insulating coating 12b. At an end of the electric wire 12, the insulating coating 12b is removed to expose the core wire 12a.

[0013] The male terminal 8 is obtained by performing press processing on a metal plate. As shown in FIG. 2, the male terminal 8 includes a bottom wall 80 overlapped on the end of the electric wire 12, a pair of covering crimping pieces 83 and a pair of core crimping pieces 82 standing on both ends of the bottom wall 80 in the width direction, a locking portion 84 connected to the bottom wall 80, and a rod portion 81 connected to the locking portion 84. The pair of covering crimping pieces 83 crimp the portion of the electric wire 12 covered with the insulating covering 12b. The pair of core crimping pieces 82 crimp the exposed core wire 12a of the electric wire 12. The locking portion 84 is a portion between the pair of core crimping pieces 82 and the rod portion 81, and is locked by a locking lance of the male housing 6. The rod portion 81 is a portion electrically connected to the female terminal 5 of the female connector 1, and is formed in a long and thin rod shape.

[0014] The male housing 6 is made of insulating synthetic resin and includes a plurality of terminal accommodating chambers 61 that accommodate the rear half of each male terminal 8, an accommodating section 62 that accommodates the rod portion 81, which is the front half of the plurality of male terminals 8, and a spacer mounting section 64. The accommodating section 62 is a section that receives the female connector 1 and is formed in a box shape that opens on the opposite side to the terminal accommodating chambers 61. A through hole is formed in the back wall of the accommodating section 62 for passing the rod portion 81 through. A lock protrusion 63 is formed at the front end inside the accommodating section 62 to maintain the mated state with the female connector 1. The spacer mounting section 64 is formed by cutting out the outer wall of each terminal accommodating chamber 61.

[0015] The spacer 7 is attached to the spacer attachment portion 64 and disposed below the core wire tightening pieces 82 of each male terminal 8 to prevent the male terminals 8 from coming out. In this manner, the male connector 2 double-locks the male terminals 8 with the locking lances provided on the male housing 6 and the spacer 7, thereby preventing the male terminals 8 from coming out.

[0016] In this specification, the male connector 2 is defined as the female connector 1 side in the mating direction with the female connector 1 as the "front" and the opposite side as the "rear". The direction in which the multiple male terminals 8 are arranged is defined as the "left-right direction", and the direction perpendicular to the mating direction and the left-right direction is defined as the "up-down direction". Similarly, the female connector 1 is defined as the male connector 2 side in the mating direction with the male connector 2 as the "front" and the opposite side as the "rear". The direction in which the multiple female terminals 5 are arranged is defined as the "left-right direction", and the direction perpendicular to the mating direction and the left-right direction is defined as the "up-down direction". The up-down direction is expressed as "up" and "down" based on the paper direction of Figures 1 to 3. These directions are used for convenience in this specification and do not necessarily coincide with the directions in a situation in which the female connector 1 and the male connector 2 are actually used.

[0017] The female connector 1 comprises multiple (5-pole in this example) female terminals 5 connected to the ends of electric wires 11, a female housing lower part 3 that accommodates the multiple female terminals 5, and a female housing upper part 4 that is engaged with the female housing lower part 3.

[0018] The electric wire 11 is a coated electric wire in which a conductive core wire 11a is coated with an insulating coating 11b. At an end of the electric wire 11, the insulating coating 11b is removed to expose the core wire 11a.

[0019] The female terminal 5 is obtained by performing press work on a metal plate, etc. As shown in Fig. 11, the female terminal 5 includes a bottom wall 50 overlapped on an end of the electric wire 11, a pair of covering crimping pieces 53 standing on both ends in the width direction of the bottom wall 50, a pair of core wire crimping pieces 52, and a pair of connecting walls 54, and a fitting portion 51 into which the male terminal 8 fits.

[0020] The pair of covering crimping pieces 53 crimp the portion of the electric wire 11 covered with the insulating covering 11b. The pair of core wire crimping pieces 52 (corresponding to the "electric wire connection portion") crimp the exposed core wire 11a of the electric wire 11. The pair of connecting walls 54 (corresponding to the "middle portion") are provided between the fitting portion 51 and the pair of core wire crimping pieces 52, and connect the rear end of the fitting portion 51 and the front end of the core wire crimping pieces 52.

[0021] The fitting portion 51 is formed in a square tube shape capable of receiving the rod portion 81 of the male terminal 8. The fitting portion 51 is continuous with the bottom wall 50 and the pair of connecting walls 54. As shown in Fig. 16, the upper end of the fitting portion 51 is disposed above the upper end of the connecting walls 54. The rod portion 81 is inserted (i.e., engaged) into the fitting portion 51, whereby the male terminal 8 and the female terminal 5 are electrically connected.

[0022] The female housing lower part 3 is made of insulating synthetic resin. As shown in Figs. 7 to 11, the female housing lower part 3 is formed in a rectangular parallelepiped shape having an upper surface 3a, a lower surface 3b, a front surface 3c, a rear surface 3d, and left and right side surfaces 3e, 3f. The female housing lower part 3 is provided with a plurality of terminal accommodating chambers 31 that accommodate female terminals 5. The plurality of terminal accommodating chambers 31 are provided side by side in the left and right direction of the female housing lower part 3.

[0023] Each terminal accommodating chamber 31 is recessed from the upper surface 3a of the female housing lower part 3, and has a trough shape that opens in three directions, the upper surface 3a, the front surface 3c, and the rear surface 3d. The female terminal 5 has a fitting portion 51 disposed in the front half of the terminal accommodating chamber 31, a connecting wall 54 disposed in the middle of the terminal accommodating chamber 31, and a core wire crimping piece 52 and a coating crimping piece 53 disposed in the rear half of the terminal accommodating chamber 31. The electric wire 11 connected to the female terminal 5 is led out from the rear end of the terminal accommodating chamber 31.

[0024] A cutout portion 33 is formed in the wall 32 between adjacent terminal accommodating chambers 31. The cutout portion 33 is formed at a position in the wall 32 corresponding to a middle portion of the terminal accommodating chamber 31. That is, as shown in Fig. 16, the cutout portion 33 is formed at an upper position on the rear side of the connecting wall 54 or at an upper position on the front side of the connecting wall 54 when viewed from the side. A protrusion 43, which will be described later, is arranged in the cutout portion 33 and above the connecting wall 54.

[0025] The female housing lower part 3 has a front wall 36 against which the front end of the fitting portion 51 abuts, a male terminal insertion opening 37 formed by cutting out the front wall 36, and a taper 37a that guides the rod portion 81 of the male terminal 8 into the male terminal insertion opening 37. The male terminal insertion opening 37 is formed in the front wall 36, so that the terminal accommodating chamber 31 opens to the front surface 3c. The female terminal 5 is in a regular position when the front end of the fitting portion 51 abuts against the front wall 36. The female terminal 5 is in a partially inserted state when there is a gap between the front end of the fitting portion 51 and the front wall 36.

[0026] A groove 34 extending in the up-down direction is formed on both the left and right side surfaces 3e, 3f of the female housing lower part 3. A locking projection 35 extending in the front-rear direction like a rib is formed on the inner surface of the groove 34. As shown in FIG. 8, a taper 35a is formed at the tip of the locking projection 35. A hanging plate portion 44 described later is disposed in the groove 34. The locking projection 35 is disposed within a locking portion 45 formed in the hanging plate portion 44. In this manner, the hanging plate portion 44 is disposed in the groove 34, and the locking projection 35 is disposed within the locking portion 45, whereby the female housing upper part 4 and the female housing lower part 3 are locked together.

[0027] A rib 38 that protrudes downward and extends in the left-right direction is formed on the rear end of the lower surface 3b of the female housing lower part 3. This rib 38 can be used as a pressing surface when the female connector 1 and the male connector 2 are mated together.

[0028] The female housing upper part 4 is made of insulating synthetic resin and includes a plate portion 41, a protruding portion 43, a pair of hanging plate portions 44, a lock arm 42, and a lock protection wall 46, as shown in Figs.

[0029] The plate portion 41 is formed in a rectangular plate shape and is placed on the upper surface 3a of the female housing lower part 3. This closes the upper openings of the multiple terminal accommodating chambers 31.

[0030] The protruding portion 43 protrudes from the lower surface 41b of the plate portion 41 and extends in the left-right direction in a rib-like manner. As described above, the protruding portion 43 is disposed within the cutout portion 33 of the female housing lower part 3 and above the connecting wall 54 in the terminal accommodating chamber 31 (i.e., behind the fitting portion 51) to prevent the female terminal 5 from slipping out rearward. In this example, one protruding portion 43 extending in a rib-like manner is provided, but multiple protruding portions may be provided at positions corresponding to the respective female terminals 5. In that case, the cutout portion 33 can be omitted.

[0031] Since the present female connector 1 is provided with the protrusion 43, it is not necessary to provide a locking lance for preventing the female terminal from coming off, as is provided in conventional products, and therefore the locking lance is omitted.

[0032] The pair of hanging plate portions 44 hang down from the lower surface 41b of the plate portion 41. The pair of hanging plate portions 44 are disposed on both sides of the protruding portion 43. The above-mentioned locking portion 45 is formed on the mutually opposing surfaces of the pair of hanging plate portions 44. The locking portion 45 extends in a groove shape in the front-rear direction.

[0033] One of the hanging plate parts 44 is disposed in a groove 34 formed in the side surface 3e of the female housing lower part 3, and a locking projection 35 protruding from the inner surface of this groove 34 is disposed in a locking portion 45 formed in one of the hanging plate parts 44. The outer surface of one of the hanging plate parts 44 (the surface opposite to the other hanging plate part 44) is disposed on the same plane as the side surface 3e.

[0034] The other hanging plate portion 44 is disposed in a groove 34 formed in the side surface 3f of the female housing lower part 3, and a locking projection 35 protruding from the inner surface of this groove 34 is disposed in a locking portion 45 formed in the other hanging plate portion 44. As a result, the female housing upper part 4 and the female housing lower part 3 are locked together. The outer surface of the other hanging plate portion 44 (the surface opposite to the one hanging plate portion 44) is disposed on the same plane as the side surface 3f.

[0035] As described above, the female housing lower part 3 is disposed between the pair of hanging plate parts 44, thereby restricting misalignment in the left-right direction between the female housing upper part 4 and the female housing lower part 3. Furthermore, the hanging plate parts 44 are disposed in the grooves 34, thereby restricting misalignment in the front-rear direction between the female housing upper part 4 and the female housing lower part 3. Furthermore, the locking projections 35 are disposed in the locking parts 45, thereby restricting misalignment in the up-down direction between the female housing upper part 4 and the female housing lower part 3.

[0036] As shown in Fig. 15, the lower end of each hanging plate portion 44 is disposed above the lower surface 3b of the female housing lower part 3. Also, as shown in Fig. 3, when the female connector 1 is mated with the male connector 2, a gap S1 is formed between the lower end of the hanging plate portion 44 and the inner surface of the accommodating portion 62. This makes it possible to prevent the hanging plate portion 44 and the accommodating portion 62 from being damaged when the female connector 1 is mated with the male connector 2.

[0037] In FIG. 15, only one female terminal 5 is shown, and the other four are not shown.

[0038] 15 and 18, a taper 44a is formed on the lower end of each hanging plate portion 44. Therefore, a gap S2 is formed between the taper 44a and the inner surface of the groove 34. This gap S2 is formed for inserting a jig 9 for releasing the engagement between the female housing upper part 4 and the female housing lower part 3.

[0039] As shown in Figure 18, when the jig 9 is inserted into the gap S2 so as to contact the taper 44a, and a force is applied in the direction of arrow D1 with the tip of the jig 9 in contact with the female housing lower part 3 at contact point P, the jig 9 applies a force to the taper 44a in the direction of arrow D2. By operating the jig 9 in this state, the hanging plate portion 44 is bent outward as shown in Figure 19. By lifting the female housing upper part 4 from this state, the hanging plate portion 44 is disengaged from the locking projection 35 as shown in Figure 20, i.e., the lock is released, and the female housing upper part 4 can be removed.

[0040] The locking arm 42 comprises an arm portion 42a that is connected to the front end of the upper surface 41a of the plate portion 41 and extends rearward in a plate-like shape, a protrusion portion 42b formed in the longitudinal center of the arm portion 42a, and a release operating portion 42c formed at the longitudinal rear end, i.e., the free end, of the arm portion 42a.

[0041] When the female connector 1 is mated with the male connector 2, the arm portion 42a is bent toward the plate portion 41, and the protrusion portion 42b overcomes the lock protrusion 63 of the male housing 6, thereby maintaining the mated state between the female connector 1 and the male connector 2. When releasing the mated state between the female connector 1 and the male connector 2, the release operation portion 42c is pressed to bend the arm portion 42a toward the plate portion 41, and the female connector 1 is pulled out backwards.

[0042] The lock protection wall 46 is connected to the rear end of the upper surface 41a of the plate portion 41, and surrounds all four sides of the release operation portion 42c together with the plate portion 41. The provision of this lock protection wall 46 prevents the release operation portion 42c from being unintentionally pressed by, for example, hitting it with some object.

[0043] As shown in Figure 2, when the female connector 1 having the above configuration is engaged with the male connector 2, its front half is disposed within the accommodating portion 62 of the male connector 2, and the release operation portion 42c, the lock protection wall 46, and the rib 38 are disposed outside the accommodating portion 62.

[0044] Next, a description will be given of an example of a method for manufacturing the female connector 1. The female connector 1 is manufactured by an automatic machine.

[0045] 11 and 12, the female terminal 5 connected to the electric wire 11 is set in the terminal accommodating chamber 31 of the female housing lower part 3 with the front end of the fitting portion 51 abutting the front wall 36. This terminal setting process is performed by grasping the female terminal 5 with an arm of an automatic machine and placing the female terminal 5 in the terminal accommodating chamber 31 from above the female housing lower part 3. In other words, there is no need to insert the female terminal 5 from the rear end of the female housing lower part 3 into the terminal accommodating chamber 31 (a highly precise operation would be required if an automatic machine were to be used).

[0046] Next, the camera uses image recognition to determine whether the female terminal 5 is in contact with the front wall 36. If the terminal is partially inserted, this can be identified by image recognition alone. If it is determined that the female terminal 5 is in contact with the front wall 36, the process proceeds to the next step.

[0047] 14 and 15, the female housing upper part 4 is placed on the upper surface 3a of the female housing lower part 3, and the female housing upper part 4 is engaged with the female housing lower part 3. When the female housing upper part 4 is engaged with the female housing lower part 3 in this process, the manufacture of the female connector 1 is completed.

[0048] 17, when the female terminal 5 is partially inserted into the terminal accommodating chamber 31, the protrusion 43 of the female housing upper part 4 interferes with the fitting part 51 of the female terminal 5, and the female housing upper part 4 cannot be locked into the female housing lower part 3. This makes it possible to recognize that the terminal is partially inserted.

[0049] In this example, as described above, the presence or absence of a partially inserted terminal is checked by camera judgment. Therefore, a state in which the female housing upper part 4 cannot be engaged with the female housing lower part 3 hardly occurs, and even if the camera judgment were omitted, the female housing upper part 4 would not be engaged with the female housing lower part 3 when the terminal is partially inserted. Therefore, unlike conventional products, there is no need to check for the presence or absence of a partially inserted terminal after manufacturing is completed.

[0050] In this way, the female connector 1 has a female housing made up of an upper part 4 and a lower part 3, and the terminal receiving chamber 31 is gutter-shaped with openings in three directions, the upper surface 3a, the front surface 3c, and the rear surface 3d, so that the terminal setting process by an automatic machine does not require highly accurate work. Also, since the female housing upper part 4 cannot be locked to the female housing lower part 3 when the terminal is partially inserted, there is no need to check whether the terminal is partially inserted after manufacturing is completed. In conventional products, a special jig must be inserted into the narrow space of the female housing to check whether the terminal is partially inserted, which hinders manufacturing by an automatic machine. These factors make it possible to manufacture by an automatic machine.

[0051] Furthermore, when disassembling the female connector 1, as described above, the engagement between the female housing upper part 4 and the female housing lower part 3 can be easily released by inserting the jig 9 into the gap S2 between the female housing upper part 4 and the female housing lower part 3. When the female housing upper part 4 is removed from the female housing lower part 3, all of the female terminals 5 can be simultaneously removed from the female housing lower part 3. Therefore, the female connector 1 can be easily disassembled in a short time.

[0052] The above-described embodiment merely shows a typical form of the present invention, and the present invention is not limited to this embodiment. In other words, the present invention can be embodied in various modifications without departing from the gist of the present invention. As long as the configuration of the present invention is still provided even with such modifications, it is of course included in the scope of the present invention. [Explanation of symbols]
