The height of the main body 310 in the height direction Z is the height of the transition portion 130 of the connector terminal 100 rather than the height between the upper surface 225c of the core lower surface 225 and the lower surface 224c of the main body receiving portion 228 of the core upper surface 224. It is said to be a small height.

The main body 310 has a box opening 313 that allows the box portion 110 of the connector terminal 100 to be inserted when the retainer 300 is in a predetermined position (temporary locking position) in the retainer insertion slot 250. , A plurality of transition portion openings 314 communicating with the box portion opening 313 in the width direction are formed. In the present embodiment, the main body 310 of the retainer 300 has the opening 313 for the box portion and the opening 314 for the transition portion in the insertion direction (width direction Y) of the retainer, and the base 210 and the core of the housing 200 described above. The number of the box portion accommodating paths 221 and the crimping portion accommodating paths 211 formed in the 220 in the insertion direction (width direction Y) of the retainer is the same as the number of the box portion accommodating paths 221 and each box portion opening 313 is adjacent to another connector terminal. It communicates with the transition opening for receiving the transition 130 of 100.

Specifically, the number of connector terminals 100 incorporated in the connector 10 is the same as the number in the width direction Y, that is, three box opening openings 313 (313a, 313b, 313c) and three transitional opening 314 (314a, 314b). 314c) are formed on the same straight line along the width direction Y. Each box portion opening 313 has a box portion of the core 220 when the main body portion 310 of the retainer 300 is inserted from the retainer insertion slot 250 into the main body receiving portion 228 of the core 220 and the retainer 300 is in the temporary locking position. It is formed at a position that is in the same linear shape as the accommodation path 221 in the insertion direction X.

The box portion opening 313 and the transition portion opening 314 that receive one connector terminal 100 communicate with the box portion opening 313 and the transition portion opening 314 that receive another connector terminal 100 adjacent to each other in the width direction Y. Therefore, in this embodiment, the box opening 313a communicates with the transition opening 314a for the same terminals that this opening accepts, and the transition opening 314a is another adjacent connector terminal. It communicates with the box opening 313b that receives 100, the box opening 313b communicates with the transition opening 314b that accepts the same connector terminal 100, and this transition opening 314b is adjacent to yet another. It communicates with the opening 313c for the box portion that receives the connector terminal 100, and the opening 313c for the box portion communicates with the opening 314c for the transition portion that receives the same connector terminal 100.

Each box portion opening 313 has a connector terminal 100 from an appropriate position when the connector terminal 100 is inserted from the box portion opening 313 of the retainer 300 into the box portion accommodating path 221 of the housing 200. The shape is such that the insertion is blocked when the connector is rotated about the insertion axis (insertion direction X). For example, the shape of the opening 313 for the box portion is a shape corresponding to the shape outside the cross section of the box portion 110 having a vertically asymmetric shape (or a shape corresponding to the shape outside the cross section of the box having a left-right asymmetric shape). That is, in the present embodiment, the height of the opening 313 for the box portion is substantially rectangular, which is the same as or slightly larger than the height H _box of the box portion 110 of the connector terminal 100, and the base thereof has a flat shape. On the other hand, the upper side has a shape with an upwardly dented recess in the central part thereof.

Further, the size (size of the height direction Z) of each transition portion opening 314 in the direction orthogonal to the insertion direction (width direction Y) of the retainer 300 is formed to be smaller than the size of the box portion opening 313. Has been done. Specifically, the height of the transition portion opening 314 is smaller than the height H _box of the box portion 110 of the connector terminal 100, and is larger than the height of the transition portion 130 of the connector terminal 100.

Further, on the lower surface 316 of the main body 310 of the retainer 300, the recesses 317a to 317c for the box portion (hereinafter collectively referred to as the box portion) are located at the same positions as the above-mentioned openings 313a to 313c for the box portion in the width direction Y. A recess 317) is formed. Each box portion recess 317 has substantially the same shape as the upper portion of the box portion opening 313 described above, and the upper side corresponding to the upper side of the box portion opening 313 and the upper side thereof face upward in the central portion thereof. It has a shape with a dented dent.

Here, when the main body 310 of the retainer 300 is inserted from the retainer insertion slot 250 into the main body receiving portion 228 of the core 220 and the retainer 300 is in the temporary locking position, the lower arm 330 of the retainer becomes the core lower surface 225 of the core 220. Since the outer shell 230 is located between the upper surface 232a and the upper surface 232a of the outer shell bottom surface 232, the lower surface 316 of the main body 310 faces the upper surface 225c of the core lower surface 225. At this time, the height from the upper surface 225c of the core lower surface 225 to the upper side of the box portion recess 317 is substantially equal to the height of the box portion opening 313 described above, and the height from the upper surface 225c of the core lower surface 225 to the box portion recess 317. The height of the recess is substantially equal to the height from the bottom of the box opening 313 to the recess 313X described above. Further, at the temporary locking position, the height from the upper surface 225c of the core lower surface 225 to the lower surface 316 of the main body 310 of the retainer 300 is substantially equal to the height of the transition portion opening 314 described above.

Next, the waterproof seal 400 will be described with reference to FIG. Note that FIG. 6 is a perspective view of the waterproof seal 400 of the connector 10 of the present embodiment. The waterproof seal 400 has a shape capable of being waterproof by contacting the inner walls of the outer shell upper surface 231, the outer shell bottom surface 232, the outer shell left side surface 233, and the outer shell right side surface 234 whose outer shape constitutes the outer shell 230 of the housing 200. It has an opening 405 inside which the core 220 of the housing 200 is inserted. The waterproof seal 400 is made of an elastic material. Further, on the outer surface 410 of the waterproof seal 400, a plurality of convex portions 411 are formed along the directions orthogonal to the insertion direction X (that is, the width direction Y and the height direction Z). Further, a plurality of groove-shaped portions 421 are formed on the inner surface 420 of the waterproof seal 400 along the directions orthogonal to the insertion direction X (that is, the width direction Y and the height direction Z). The waterproof seal 400 is inserted into the innermost portion 241 of the mating connector insertion slot 240 of the housing 200 when the connector 10 is assembled.

Next, a method of assembling the connector 10 will be described. As shown in FIG. 1, first, the waterproof seal 400 is inserted into the mating connector insertion slot 240 in the direction opposite to the insertion direction X, that is, in the removal direction, and the waterproof seal 400 is arranged in the innermost portion 241 of the slot. At this time, the waterproof seal 400 is in close contact with the periphery of the core 220 due to the plurality of groove-shaped portions 421 formed on the inner surface 420 of the waterproof seal 400.

The retainer 300 is then inserted into the retainer insertion slot 250 of the housing 200. Then, the main body 310 of the retainer 300 enters the main body receiving portion 228 of the core 220. Further, the upper arm 320 of the retainer 300 is inserted between the lower surface 231a of the outer shell upper surface 231 of the housing 200 and the core upper surface 224 of the core 220. Further, the lower arm 330 of the retainer 300 is inserted between the upper surface 232a of the outer shell bottom surface 232 of the housing 200 and the core lower surface 225 of the core 220. When the retainer 300 is inserted into the retainer insertion slot 250 and moved in the width direction Y, the upper locking projection 322 of the upper arm 320 of the retainer 300 is formed on the core upper surface 224 of the core 220. The lower locking projection 332 of the lower arm 330 of the retainer 300 is locked to the first locking groove 225a formed on the core lower surface 225 of the core 220. At this time, the retainer 300 is in the temporary locking position.

At this temporary locking position, the box portion opening 313 and the box portion recess 317 formed in the main body portion 310 of the retainer 300 are formed in the crimping portion accommodating path 211 and the box portion accommodating path 221 of the housing 200 and the insertion direction X. The positions are aligned on a straight line.

At this temporary locking position, the connector terminal 100 to which the conducting wire 180 is crimp-connected to the crimping portion 120 is inserted into the crimping portion accommodating path 211 from the terminal insertion opening 213 of the base 210 of the housing 200. Since the shape of the crimping portion accommodating path 211 is a circle larger than the outer shape of the box portion 110 of the connector terminal 100, the box portion 110 of the connector terminal 100 passes through the crimping portion accommodating path 211 without being hindered, and the retainer 300 The opening 313 for the box portion or the recess 317 for the box portion of the main body 310 is reached, and the opening 313 for the box portion of the retainer 300 allows the box portion 110 to enter the insertion direction X. When the connector terminal 100 is further moved in the insertion direction X, the box portion 110 is inserted into the box portion accommodating path 221 of the core 220. That is, the connector terminal 100 is inserted into the box portion accommodating path 221 from the crimping portion accommodating path 211 through the box portion opening 313 or the box portion recess 317.

Here, a state in which the connector terminal 100 is partially inserted into the box portion accommodating path 221 will be described with reference to FIG. 7. 7 (A) is a cross-sectional perspective view corresponding to FIG. 3 (C) when the box portion 110 of the connector terminal 100 is partially inserted into the box portion accommodating path 221. FIG. 7 (B) is FIG. It is a partially enlarged view of the VIIB part of (A).

In FIGS. 7A and 7B, the box portion 110 of the connector terminal 100 located on the upper side is the lower side of the lower surface 291A of the base portion of the lance base 291 of the lance 229 formed in the upper box portion accommodating path 221U. It is inserted between the upper surface surface 291B of the base portion of the lance base 291 of the lance 229 formed in the box portion accommodating path 221L. At this time, there is a space slightly larger than the height of the locking projection 116 between the upper plate 111 of the box portion 110 and the lower surface 291A of the base portion, and the box portion 110 can move in the insertion direction X.

When the box portion 110 further moves in the insertion direction X as the connector terminal 100 moves in the insertion direction X, the locking projection 116 of the box portion 110 slides on the first tapered surface 292A of the cantilever-shaped portion 292 of the lance 229. While touching, the cantilever-shaped portion 292 of the lance 229 is pushed up Z upward in the height direction. At this time, the cantilever-shaped portion 292 of the lance 229 swivels upward with the lance base 291 as a fulcrum. When the box portion 110 is further moved in the insertion direction X, the locking projection 116 of the box portion 110 is in the order of the lever lower surface 292B of the cantilever-shaped portion 292, the second tapered surface 293B of the terminal locking portion 293, and the locking portion lower surface 293C. During the sliding contact, the lance 229 maintains a state of being lifted upward with the lance base 291 as a fulcrum as a whole.

Next, when the locking projection 116 of the box portion 110 moves in the insertion direction X while sliding in contact with the lower surface 293C of the locking portion of the terminal locking portion 293 and reaches the contact surface 293A of the terminal locking portion 293, the locking projection The contact between the 116 and the lower surface 293C of the locking portion is lost, and as shown in FIG. 8, the lance 229 swivels downward with the lance base 291 as a fulcrum and returns to the original shape. 8 (A) is a cross-sectional perspective view corresponding to FIG. 3 (C) when the box portion 110 of the connector terminal 100 is completely inserted into the box portion accommodating path 221. FIG. 8 (B) is a view. 8 (A) is a partially enlarged view of a VIIIB portion.

As shown in FIGS. 8A and 8B, when the box portion 110 of the connector terminal 100 is completely inserted into the box portion accommodation path 221, the contact insertion hole 115 of the box portion 110 of the connector terminal 100 is inserted. Is located just behind the insertion direction X of the male terminal insertion opening 223 of the core 220. Further, the locking projection 116 is locked to the contact surface 293A of the terminal locking portion 293 on the rear surface side in the insertion direction X, and the movement of the box portion 110 in the removal direction is prevented. Further, a part of the lower side of the terminal locking portion 293 of the lance 229 is inserted into the upper surface opening 119 of the upper plate 111 of the box portion 110, and as a result, the movement of the box portion 110 in the removal direction is surely prevented. To.

Further, at this time, the jig contact portion 294 extends beyond the locking projection 116 in the insertion direction X on one side of the locking projection 116 in the width direction Y. A predetermined gap S is formed under the lower surface 294A of the jig rest portion of the jig rest portion 294.

When the box portion 110 of the connector terminal 100 is completely inserted into the box portion accommodating path 221 as shown in FIGS. 8A and 8B, the transition portion 130 of the connector terminal 100 becomes the box portion of the retainer 300. It is located at the lower part of the opening 313 and the lower part of the box recess 317. This makes it possible to further move the retainer 300 in the width direction Y. On the other hand, when the box portion 110 is not completely accommodated in the box portion accommodating path 221, the left side plate 113 of the box portion 110 exists in the box portion opening 313 and the box portion recess 317, and at this time, the retainer Even if the 300 is to be moved in the width direction Y, the left plate 113 of the box portion 110 prevents the 300 from moving in the width direction Y. This makes it possible to detect that the connector terminal 100 is half-inserted, that is, that the connector terminal 100 is not completely accommodated in the box portion accommodating path 221.

As described above, when the box portion 110 of the connector terminal 100 is completely inserted into the box portion accommodating path 221, the retainer 300 can be moved in the width direction Y. When the retainer 300 is further moved in the width direction Y, the upper locking projection 322 of the upper arm 320 of the retainer 300 disengages from the first locking groove 224a formed on the core upper surface 224 of the core 220 and moves in the width direction Y. , Locked in the second locking groove 224b. Similarly, the lower locking projection 332 of the lower arm 330 of the retainer 300 disengages from the first locking groove 225a formed on the core lower surface 225 of the core 220 and moves in the width direction Y, and engages with the second locking groove 225b. It will be stopped. At this time, the retainer 300 is in the main locking position.

At this time, since the height of the opening 314 for the transition portion is smaller than the height H _box of the box portion 110 of the connector terminal 100, the front end surface 319 of the main body portion 310 of the retainer 300 is the rear end surface of the box portion 110 of the connector terminal 100. Contact with 118. Further, since the height from the upper surface 225c of the core lower surface 225 to the lower surface 316 of the main body 310 adjacent to the box portion recess 317 of the retainer 300 is smaller than the height H _box of the box portion 110 of the connector terminal 100. The front surface 319 of the main body 310 of the retainer 300 comes into contact with the rear end surface 118 of the box 110 of the connector terminal 100. That is, when the retainer 300 is in the main locking position, the transition portion 130 of the connector terminal 100 is housed in the transition portion opening 314 of the retainer 300, so that even if the connector terminal 100 is to be pulled out in the removal direction in this state. When the rear end surface 118 of the box portion 110 abuts on the front surface 319 of the main body portion 310 of the retainer 300, the box portion 110 is prevented from moving backward, and the box portion 110 cannot be removed. This prevents the connector terminal 100 from falling off from the housing 200.

Next, a method of removing the connector terminal 100 from the housing 200 will be described. First, the retainer 300 is moved from the main locking position to the temporary locking position. Then, the box portion opening 313 and the box portion recess 317 of the main body portion 310 of the retainer 300 are aligned with the crimping portion accommodating path 211 and the box portion accommodating path 221 of the housing 200 in the insertion direction X. However, at this point, since the locking projection 116 of the box portion 110 of the connector terminal 100 is still locked to the contact surface 293A of the terminal locking portion 293 of the lance 229, the connector terminal 100 is pulled out in the extraction direction. Can't.

Therefore, as shown in FIGS. 9 and 10, the lance 229 is lifted upward by using a jig or a tool to release the locking between the locking projection 116 and the contact surface 293A of the terminal locking portion 293. 9 (A) is a cross-sectional perspective view corresponding to FIG. 8 (A) when the dedicated jig 500 is inserted into the gap S, and FIG. 9 (B) is an enlarged perspective view of the IXB portion of FIG. 9 (A). 10 (A) is a cross-sectional perspective view corresponding to FIG. 8 (A) in a state where a general tool 600 is inserted into the gap S, and FIG. 10 (B) is an XB portion of FIG. 10 (A). It is an enlarged perspective view of.

As shown in FIG. 9A, the dedicated jig 500 includes a long grip portion 510, an intermediate portion 520 protruding from the tip of the grip portion, and an operating portion 530 protruding from the tip of the intermediate portion 520. The intermediate portion 520 has a square or rectangular cross-sectional shape, and at least one of the heights or widths is made larger than the height or width of the tool insertion opening 226 of the housing 200 described above, and the intermediate portion 520 is used for inserting tools. It is formed in a size that cannot be inserted into the opening 226. The actuating portion 530 is formed in a height and width sized to be inserted into the tool insertion opening 226 described above. The length of the actuating portion 530 is longer than the length from the tool insertion opening 226 to the jig contact portion 294 of the lance 229. At the tip of the actuating portion 530, a jig tapered surface 532 inclined so as to have an acute angle with respect to the bottom surface 531 of the actuating portion 530 is formed.

The operating portion 530 of the special jig 500 is inserted into the tool insertion opening 226 of the housing 200 and moved in the removal direction. Then, the jig tapered surface 532 of the operating portion 530 comes into contact with the third tapered surface 294B of the jig contact portion 294 of the lance 229. When the special jig 500 is further moved in the removal direction in this state, the third tapered surface 294B of the jig contact portion 294 is pushed upward along the jig tapered surface 532 by the movement of the jig tapered surface 532 in the removal direction. As a result, the lance 229 swivels upward in the height direction Z with the lance base 291 as a fulcrum.

Then, the lower surface 293C of the locking portion is released from the upper surface opening 119 of the box portion 110 of the connector terminal 100, and is further lifted upward to a position relatively higher than the locking projection 116 in the height direction Z. As a result, the connector terminal 100 on the contact surface 293A of the terminal locking portion 293 is unlocked from the locking projection 116 of the box portion 110, and the connector terminal 100 can be pulled out in the removal direction.

The connector 10 of the present invention is a lance even if a general tool 600 such as a flat-blade screwdriver is used as shown in FIGS. 10 (A) and 10 (B) without using the dedicated jig 500. The contact surface 293A of the terminal locking portion 293 of the 229 can be released from the locking projection 116 of the connector terminal 100. The tool 600 includes a grip portion 610, a shaft portion 620 protruding from the tip of the grip portion 610, and a thin flat plate-shaped cutting edge 630 formed at the tip of the shaft portion 620.

Similar to the case of the dedicated jig of FIGS. 9A and 9B, the cutting edge 630 of the tool 600 is inserted into the box portion accommodating path 221 from the tool insertion opening 226 of the housing 200. After that, the cutting edge 630 is moved in the removal direction, and the cutting edge 630 is inserted into the gap S between the upper plate 111 of the box portion 110 of the connector terminal 100 and the lower surface 294A of the jig contact portion 294 of the jig contact portion 294 of the lance 229. Move the 630 upwards. Then, the jig contact portion 294 of the lance 229 is lifted upward, and the entire lance 229 swivels upward in the height direction Z with the lance base 291 as a fulcrum. As a result, the lower surface 293C of the locking portion is released from the upper surface opening 119 of the box portion 110 of the connector terminal 100, and is further lifted upward to a position relatively higher in the height direction Z than the locking projection 116. As a result, the connector terminal 100 on the contact surface 293A of the terminal locking portion 293 is unlocked from the locking projection 116 of the box portion 110, and the connector terminal 100 can be pulled out in the removal direction.

According to the connector 10 described above, the jig contact portion 294 of the lance 229 is more of a tool or jig than the terminal locking portion 293 for locking the locking projection 116 formed on the box portion 110 of the connector terminal 100. Since it is on the front side when viewed from the insertion direction, it becomes easy for the tool or jig to reach the jig contact portion 294, and the operability is improved.

In the above embodiment, there is no wall surface partitioning between the box portion accommodating path 221U on the upper side of the housing 200 and the lower box portion accommodating path 221L, and the lance 229 projecting from the side plate 221B to the lower box portion accommodating path 221L. An example was described in which only the upper and lower box portion accommodation paths 221 exist. However, the present invention is not limited to the above configuration, and as shown in FIG. 11, between the upper box portion accommodating path 221U and the lower box portion accommodating path 221L, from the side plate 221B toward the width direction Y. The configuration may be such that a protruding protective wall 221P is present. FIG. 11 is an enlarged cross-sectional perspective view of the housing 200 when the protective wall 221P is provided between the upper box portion accommodating path 221U and the lower box portion accommodating path 221L.

The protective wall 221P has an upper box portion accommodating path 221U and a lower box portion from directly below the male terminal insertion opening 223 of the upper box accommodating path U to the lance base 291 of the lance 229 provided in the lower box accommodating path L. It is formed so as to be partially separated from the accommodation path 221L. The protective wall 221P may completely connect the side plates 221B so as to completely separate the upper box portion accommodating path 221U and the lower box portion accommodating path 221L, but in the present embodiment, the jig contact of the lance 229 The structure is such that only a predetermined width protrudes from the side plate 221B on the side on which the portion 294 is formed.

According to the configuration shown in FIG. 11, the tool 600 as shown in FIGS. 10A and 10B has a tool insertion opening 226 through the tool insertion opening 226 to the lower surface of the jig contact portion 294 of the lance 229 and the upper plate of the box portion 110. When inserted between 111 and the lance 229 is pushed upward, the upper surface of the jig contact portion 294 comes into contact with the lower surface of the protective wall 221P, and the lance 229 bends excessively upward, resulting in stress concentration and lance 229. Can be prevented from being damaged.

The lance has a terminal locking portion having a contact surface at the tip portion substantially perpendicular to the insertion direction, and the terminal locking portion from one side in the width direction orthogonal to the insertion direction toward the insertion direction. A connector with a further extended jig pad. The end face of the jig rest portion close to the connector terminal in the height direction perpendicular to the insertion direction is closer to the connector terminal in the height direction of the terminal locking portion, and the connector is closer to the connector terminal. The connector according to claim 1, which has a shape far from the terminal. The connector according to claim 2, wherein the jig contact portion has a tapered shape having a predetermined angle from a tip portion in the insertion direction toward an end surface close to the connector terminal in the height direction. A long connector terminal having at least one plane extending along the insertion direction and a locking projection protruding outward from the plane.
The connector terminal is inserted in one direction to accommodate the connector terminal, and is one of the wall surfaces forming the accommodation hole, and is along the wall surface of the connector terminal facing the plane. A connector comprising a housing comprising a lance that cantilevers into the accommodating hole in the insertion direction of the connector.
The lance has a terminal locking portion having a contact surface substantially perpendicular to the insertion direction at the tip portion, and a terminal locking portion further extending from the width direction side orthogonal to the insertion direction toward the insertion direction. Equipped with a protruding jig pad
When the connector terminal is accommodated in the accommodating hole, the terminal locking portion engages the locking projection and prevents the connector terminal from moving in the anti-insertion direction.
The jig contact portion is a connector that releases the lock of the terminal locking portion to the locking projection by being pressed by the jig in a direction away from the plane of the connector terminal.
