< Summary of connector Structure >

Features of the present disclosure relate to the construction of a housing of a connector. However, in order to grasp the entire connector structure, an outline of the connector will be described below with reference to the drawings.

Fig. 1 and 2 are perspective views schematically showing a fitted state (fig. 1) and a disengaged state (fig. 2) of a connector 1 according to one embodiment of the present disclosure with respect to a counterpart connector 2. The connector 1 (hereinafter, also referred to as a receptacle connector) of the present disclosure is electrically connected to terminals housed inside the respective connectors by being combined with a counterpart connector 2 (hereinafter, also referred to as a plug connector).

In the following description, the combination direction of the connector 1 and the counterpart connector 2 is referred to as the "up-down direction", and the counterpart connector is combined above the connector 1 arranged at a lower position in the up-down direction. That is, in the present specification, the upward direction corresponds to the "fitting-out direction X'" in which the mating connector 2 is detached from the connector 1, and the downward direction corresponds to the "fitting direction X" in which the mating connector 2 is attached to the connector 1.

The connector of the present disclosure is provided with a housing 10 capable of accommodating terminals. The housing 10 may mainly include a cylindrical portion 110, and a base portion 120 outside the cylindrical portion 110 and Zhou Jubei. The connector can be mounted to a device or the like through the base portion 120. The cylindrical portion 110 of the housing 10 has an opening 130 along the fitting direction X, and the housing 21 of the mating connector 2 can be inserted into the opening 130. The material of the case is not particularly limited, and may be formed of a metal or a resin material, for example. In the present disclosure, the housing of the connector may be an integrally formed unitary body of the same material.

Fig. 3 to 6 are schematic views of a push-on counter connector 2 and a bayonet counter connector 2B that can be combined with the connector of the present disclosure. The mating connector 2 includes a housing 21, and a terminal 25 electrically connected to a terminal (not shown) of the connector of the present disclosure is provided in the housing 21. The housing 21 of the mating connector 2 includes a cover 23 along the fitting-disengaging direction X'. The cover 23 is provided with an insertion through-hole 231, and a cable (not shown) connected to the terminal 25 can extend from the insertion through-hole 231 to the outside of the mating connector 2. The mating connector 2 further includes a fitting ring 22 positioned outside the housing 21 of the mating connector 2. The fitting ring 22 may be rotatable outside the housing 21.

< Outline of fitting mechanism of connector >

The connector 1 and the mating connector 2 can be fitted by combining the fitting ring 22 of the mating connector 2 with the housing 10 of the connector 1. In the fitted state, the fitting ring 22 of the counterpart connector 2 is combined with the housing 10 of the connector 1 at the outer periphery of the housing 10. More specifically, by combining the fitting ring 22 to the outer periphery of the cylindrical portion 110 of the housing 10, the connector 1 and the counterpart connector 2 can be locked in a fitted state. A general fitting mechanism of the screw type, push type, and bayonet type will be described below.

(Screw thread type)

For example, in the case of fitting by screw, a male screw 170 is provided on the outer periphery of the housing 10 of the connector (i.e., the receptacle connector). On the other hand, a female screw engageable with the male screw 170 is provided on the inner periphery of the mating ring of the mating connector (i.e., the plug connector). After the connector and the counterpart connector are engaged with each other, the male screw 170 of the housing 10 of the connector and the female screw of the mating connector mating ring 22 can be engaged by rotating the mating ring 22, so that the connector and the counterpart connector can be mated. In the disengagement, the mating connector may be pulled out from the connector after the engagement between the housing 10 and the fitting ring 22 is released by reversely rotating the fitting ring 22.

(Push-on type)

Fig. 3 is an exploded perspective view schematically showing an exemplary push-on counterpart connector 2. As illustrated, the push-on mating connector 2 includes a torsion coil spring 24 between the housing 21 and the fitting ring 22. Fig. 4 is a schematic cross-sectional perspective view of the fitting ring 22 of the mating connector 2 shown in fig. 3. As shown in fig. 4, a push-on claw 221 protruding toward the inside of the mating connector is formed on the inside of the fitting ring 22 of the push-on mating connector 2 (plug connector).

Fig. 13A is a schematic perspective view of a housing 10A of a receptacle connector provided with a conventional push-fit mechanism. As illustrated, the receptacle connector includes a push-on passage 140 on the outer periphery of the housing 10A. The push-on passage 140 may be opened in the opening 130 of the housing so as to be able to receive the push-on claw 221 (see fig. 4) of the counterpart connector, and may be extended in the fitting direction X, and then may terminate in the locking region 145 for locking the push-on claw 221. The push-on passage 140 may be referred to as a "push-on groove", "push-on path", or "push-on claw guide passage" when the outer peripheral surface of the housing 10A is recessed toward the inner peripheral side. The push passage 140 includes 2 guide surfaces 141 and 142 facing each other in the circumferential direction of the housing 10A. One guide surface 141 of the 2 guide surfaces, which is close to the locking region 145, is inclined such that the interval between the 2 guide surfaces becomes gradually narrower toward the fitting direction X. The other guide surface 142 may extend substantially perpendicularly with respect to the circumferential direction, alternatively may also be inclined with respect to the circumferential direction and the fitting direction X. That is, the push-on passage may include a tapered groove portion whose width gradually narrows from the opening 130 of the housing 10A toward the fitting direction X.

In the push-fit fitting method, fitting is performed by using the elastic force of the torsion coil spring 24 (see fig. 3) of the mating plug connector 2. If the plug connector 2 is inserted into the receptacle connector, the push-on claw 221 enters the push-on passage 140 from the opening portion 130 side of the housing. Thereafter, the guide surface 141 is guided along the inclined guide surface of the push-through passage 140, and enters the locking region 145 located at the end of the push-through passage 140 in the fitting direction X. If the push claw 221 enters the locking region 145, the movement in the fitting/removal fitting direction X-X' (i.e., the up-down direction in the drawing) is restricted. The guide surface 141 is inclined with respect to the circumferential direction of the housing, and thus the fitting ring 22 rotates by a predetermined angle at the time of fitting. With this rotation, the torsion coil spring 24 attached to the fitting ring 22 applies a force corresponding to the rotation angle to the push pawl 221. The engagement claw 221 is pressed against the side wall of the locking region 145 by the force involved, and is held in the locked state. Thereby, the plug connector and the receptacle connector are locked in a fitted state.

When the push-fit engagement mechanism is disengaged, the engagement ring 22 is rotated against the urging force from the torsion coil spring 24, and the push-fit claw 221 is disengaged from the engagement region 145. Thereafter, the push-on claw 221 may be pulled along the guide surface 142 in the disengagement direction X' while the plug connector is pulled out from the receptacle connector. In the fitting mechanism, the operator can easily perform the fitting operation by pressing the plug connector into the receptacle connector. Therefore, the push-on fitting mechanism can also be understood as a "one-touch" or "one-touch" fitting mechanism that can be fitted and released in one action.

(Bayonet type)

The bayonet fitting mechanism is a fitting mechanism in which a fitting state is maintained by bayonet claws 222 (see fig. 5) and bayonet grooves 150 (see fig. 13B) that can be engaged with the bayonet claws 222. Specifically, in the bayonet fitting mechanism, the bayonet claws 222 are engaged with the concave bayonet grooves 150 corresponding to the bayonet claws 222, wherein the bayonet claws 222 protrude from the inner peripheral surface of the fitting ring 22, and the bayonet grooves 150 are formed on the outer peripheral surface of the housing of the connector. In the bayonet fitting mechanism, by converting the rotational force of the fitting ring 22 into a force in the direction along the fitting/removal fitting direction X-X' of the connector, the force required for the operator to fit and remove the connector can be reduced.

Fig. 13B is a schematic perspective view of a housing 10B of a receptacle connector provided with a conventional bayonet fitting mechanism. As illustrated, the receptacle connector includes a bayonet passage 150 on the outer periphery of the housing 10B. The bayonet passage 150 may have a groove shape extending so as to be inclined toward the fitting direction X (i.e., downward in the drawing) with respect to the circumferential direction of the housing 10B, and may also be referred to as a "bayonet path" or a "bayonet claw guide path". One end of the bayonet passage 150 is opened in the opening 130 of the housing so as to be able to receive bayonet claws 222 described later, and the other end is terminated so as to be able to lock the bayonet claws 222.

Fig. 5 is a schematic perspective view of an exemplary bayonet plug connector 2B. Fig. 6 is an exploded perspective view of the bayonet plug connector 2B shown in fig. 5. The bayonet type plug connector 2B includes bayonet claws 222 protruding toward the inside of the connector 2B on the inside of the fitting ring 22. The bayonet catch 222 may have a shape complementary to the bayonet passage 150. Specifically, the bayonet claws 222 are appropriately movable along the inclined groove shape of the bayonet passage 150, and thus may have a long shape inclined at substantially the same angle as the inclination of the bayonet passage 150. In other words, the bayonet passage 150 may be inclined at the same angle as the inclination of the bayonet claws 222, while extending obliquely from the opening 130 side toward the fitting direction X with respect to the fitting direction X and the circumferential direction.

In the bayonet fitting mechanism, in a state in which the bayonet claws 222 of the plug connector 2B are accommodated in the bayonet passages 150 of the receptacle connector, the operator rotates the fitting ring 22, and moves the bayonet claws 222 to the terminals of the bayonet passages 150, whereby the two connectors are fitted. Upon disengagement, bayonet claws 222 may be disengaged from bayonet passage 150 by rotating mating ring 22 in the opposite direction as when mated. According to the structure, it is not necessary to rotate the fitting ring 22 several times as in the screw type, and fitting can be completed by, for example, rotation of less than 1 week.

< Features of the connector of the present disclosure >

Fig. 7A is a perspective view schematically showing a housing 10 of a connector according to an embodiment of the present disclosure. Fig. 7B is a schematic perspective view of the case 10 of fig. 7A from a different angle from fig. 7A. As illustrated, the connector of the present disclosure includes, in the housing 10, a combination of a push-on passage 140 that guides a push-on claw 221 (see fig. 4) of a counterpart connector (i.e., a plug connector) and a bayonet passage 150 that guides a bayonet claw 222 (see fig. 6) of a counterpart connector 2B. More specifically, the connector of the present disclosure includes both the push-on passage 140 and the bayonet passage 150 on the outer peripheral surface of the single housing 10. If the mating connector (fitting ring 22) is pushed toward the connector 2, the push-on passage 140 can guide or move the push-on claw 221 in the fitting direction X and the engagement region 145, and engagement by push-on is possible. The bayonet passage 150 can guide or move the bayonet claws 222 along the bayonet passage 150 with the rotation of the fitting ring 22, and can perform bayonet-based engagement. In other words, 2 kinds of fitting-type mechanisms for the push-on passage 140 and the bayonet passage 150 are formed on the outer peripheral surface of the housing 10 of the connector of the present disclosure.

That is, the connector of the present disclosure can correspond to either the push-on counterpart connector 2 or the bayonet counterpart connector 2B through the push-on passage 140 and the bayonet passage 150 formed on the outer peripheral surface of the single housing 10. Specifically, the connector of the present disclosure can be locked by the push-on claw 221 in the push-on passage 140 and can be locked by the bayonet claw 222 in the bayonet passage 150. Therefore, the connector according to the present disclosure can correspond to the fitting method of both the push-on type and the bayonet type.

As described above, since the plug connector (mating connector) is generally attached to the distal end of the cable, it is relatively easy to replace the connector with a connector of a different fitting type. On the other hand, since the receptacle connector can be directly attached to the main body of the device, it may be difficult to replace the receptacle connector with another connector of a fitting type. According to the present disclosure, there is provided a socket connector which can at least correspond to a plurality of fitting methods of push-fit type and bayonet type, and which is excellent in convenience in that it is not necessary to replace the socket connector with a switch of the plurality of fitting methods involved.

In addition, as shown in fig. 7A and 7B, in the connector of the present disclosure, a bayonet passage 150 is formed across the push-on passage 140. That is, the bayonet passage 150 may be formed so as to penetrate the push-through passage 140. In other words, it can be understood that the push-through passage 140 is formed so as to penetrate the bayonet passage 150. More specifically, the bayonet passage 150 may extend obliquely with respect to the fitting direction X across the push-on passage 140 extending from the opening 130 of the housing in the fitting direction X. In the above-described structure, it can be also understood that the bayonet passage 150 and the push-on passage 140 intersect each other and extend obliquely with respect to the extending direction of the push-on passage 140 (i.e., the longitudinal direction of the push-on passage). Thus, the push-on passage 140 and the bayonet passage 150 can be provided in the same region of the housing 10, and thus the present disclosure can be suitable also from the viewpoint of downsizing of the connector.

The push passage 140 and the bayonet passage 150 may be formed such that the outer peripheral surface of the housing 10 is recessed toward the inner peripheral side. As illustrated, the push channel 140 and the bayonet channel 150 extending across the push channel 140 may be integrally formed. That is, the connector of the present disclosure may be provided with a combination of the push-on passage 140 and the bayonet passage 150 formed integrally in the housing 10. By "integrally" is meant that the passages (140, 150) of the 2 engagement mechanisms abut one another or extend continuously. That is, in the housing 10 of the connector of the present disclosure, the push-on passage 140 and the bayonet passage 150 may be formed to be connected to each other. According to the structure of the present invention, the structure of the housing 10 (in particular, the structure of the outer peripheral surface) can be further simplified, and therefore, the manufacturing efficiency of the housing can be improved, and further, the decrease in the strength of the housing accompanying the formation of the passage can be suppressed.

In some suitable arrangement, push channel 140 and bayonet channel 150 may be continuous with one another. More specifically, the push channels 140 and the bayonet channels 150 may intersect with each other, and are continuous with each other at the intersection. In the related structure, the concave surface of the outer periphery of the housing 10 forming the push passage 140 and the bayonet passage 150 may be 1 surface continuous with each other. Thus, when the push claw 221 or the bayonet claw 222 moves in the corresponding passage, the hooking at the crossing portion of the passage can be suppressed, and the movement can be more appropriately performed.

Fig. 8 is a schematic development view of an upper side portion of the housing 10 of the connector of the present disclosure shown in fig. 7A, and fig. 9A and 9B are enlarged views of a portion C in the development view of fig. 8. As illustrated, in some suitable embodiment, the housing 10 includes a protrusion 160 in the push-on passage 140. The protrusion 160 is formed in the push-on passage 140 so as to protrude outward from the outer peripheral surface of the housing 10. The protrusion 160 has a main surface substantially parallel to the outer peripheral surface of the case 10, and a plurality of side surfaces connecting the main surface to the outer peripheral surface of the case 10. The protrusion 160 is disposed so as to be able to abut against the bayonet claws 222, and the push-on claw 221 is disposed so as to be able to move along the push-on passage 140. More specifically, the protrusion 160 may be positioned as follows: the bayonet claws 222 can abut against the intersection of the bayonet passage 150 and the push-on passage 140, and the push-on claws 221 can move along the push-on passage 140 in the fitting direction X.

As described above, the biasing force due to the displacement of the torsion coil spring 24 (see fig. 3) is used in the push-fit type fitting mechanism. Accordingly, the displacement amount of the torsion coil spring 24 accompanying the rotation of the fitting ring 22 is ensured, and thus the push-on passage 140 is formed so that the width gradually becomes wider toward the opening 130 side of the housing. Therefore, when the bayonet type plug connector is combined with the connector, there is a possibility that the bayonet claws 222 may erroneously enter the push-on passage 140 in some cases.

According to the present disclosure, by providing the push-through passage 140 with the protrusion 160 capable of abutting against the bayonet claws 222, erroneous entry of the bayonet claws 222 into the push-through passage 140 can be prevented. That is, the protrusion 160 helps prevent the bayonet claws 222 from erroneously entering the push-through passage 140. Accordingly, the operation efficiency of the fitting operation of the connector can be improved, and the breakage of the connector and/or the counterpart connector due to the erroneous entry of the bayonet claws 222 can be appropriately suppressed.

Specifically, the bayonet claws 222 are prevented from moving in the longitudinal extending direction (i.e., the fitting direction X) of the push-through passage 140 by abutting against the opening side surface 161 of the protrusion 160 located on the opening 130 side of the housing, out of the side surfaces of the protrusion 160. The opening side surface 161 of the protrusion 160 extends in a direction different from the longitudinal extending direction of the push-on passage 140, and may extend in the circumferential direction of the housing 10, for example. Thus, the opening side surface 161 of the protrusion 160 can function as a movement stopper surface of the bayonet claws 222 that prevents the bayonet claws 222 from moving in the longitudinal direction of the push-on passage 140. In this way, the protrusion 160 includes the stopper surface 161 that restricts the movement of the bayonet claws 222, and thus, erroneous engagement of the bayonet claws 222 can be appropriately suppressed, and it is possible to more appropriately cope with the engagement method of both the bayonet type and the push type.

As shown in fig. 9A, the push-on passage 140 having the protrusion 160 may have 2 grooves 143, 144 on both sides of the protrusion 160. The push-through passage 140 may include, on both sides of the protrusion 160, a1 st groove 143 and a2 nd groove 144 defined by guide surfaces 141 and 142 of the push-through passage 140 and side surfaces of the protrusion 160 facing the guide surfaces 141 and 142, respectively. That is, a part of the push passage 140 may be branched into 2 grooves 143, 144 by the protrusion 160. More specifically, the 1 st groove 143 can be defined by the 1 st guide surface 141 of the push-on passage 140 inclined with respect to the fitting direction X and the side surface of the projection 160 facing the 1 st guide surface 141. The 2 nd groove 144 can be defined by a2 nd guide surface 142 located on the opposite side of the 1 st groove 143 via the projection 160 and extending along the fitting direction X, and a side surface of the projection 160 facing the 2 nd guide surface 142.

The width dimension W1 of the 1 st slot 143 and the width dimension W2 of the 2 nd slot 144 are smaller than the width dimension Wb of the bayonet pawl 222 and larger than the width dimension Wp of the push pawl 221. Here, the "width dimension" of the groove portion and each claw means a dimension in the circumferential direction Y of each member. The width dimensions W1, W2, wb, and Wp are in the above-described relationship, so that the push-on claw 221 can move in the 1 st groove portion 143 and the 2 nd groove portion 144, while the passage of the bayonet claw 222 is prevented. That is, with respect to the width dimensions Wb, wp of the push-in claw 221 and the bayonet claw 222, by providing the protrusion 160 at such a position that the width dimensions W1, W2 of the 1 st groove 143 and the 2 nd groove 144 become Wb > W1 and W2 and Wp < W1 and W2, erroneous entry of the bayonet claw 222 into the push-in passage 140 can be appropriately prevented. In this way, the protrusion 160 can function to properly identify and guide the push claw 221 and the bayonet claw 222 to an appropriate passage.

The width dimensions W1 and W2 of the 1 st groove 143 and the 2 nd groove 144 are not particularly limited as long as the bayonet claws 222 are prevented from erroneously entering the push-on passage 140 and the push-on claws 221 can pass, but may be, for example, 95% or less, 90% or less, or 85% or less of the width dimension Wb of the bayonet claws 222. The width dimensions W1 and W2 of the 1 st groove 143 and the 2 nd groove 144 may be 105% or more, 110% or more, or 115% or more of the width dimension Wp of the push claw 221, for example. Note that the above range can be changed as appropriate depending on the size of the connector or the like.

According to the above-described configuration, the operation of fitting and removing the connector of the present disclosure from the push-on counterpart connector can be performed by passing the push-on claw 221 through the 1 st groove portion 143 and the 2 nd groove portion 144 of the push-on passage 140 formed by the protrusion portion 160. More specifically, the push claw 221 can enter the push passage 140 through the 1 st groove 143 during the fitting operation, and can be disengaged from the push passage 140 through the 2 nd groove 144 during the disengagement operation.

Hereinafter, a push-on fitting mechanism of a connector according to an embodiment of the present disclosure will be described with reference to the drawings. Fig. 10A to 10F are schematic development views illustrating the movement of the push claw 221 at the connector of the present disclosure. As illustrated, the connector and the counterpart connector are combined in such a manner that the push claw 221 enters from the 1 st slot portion 143 (fig. 10A). Next, if the counterpart connector is pressed into the connector, the push claw 221 is guided obliquely with respect to the fitting direction X along the 1 st guide surface 141 continuous from the 1 st groove 143 of the push passage 140 (fig. 10B and 10C). With the movement of the push claw 221, the fitting ring 22 (see fig. 3) rotates by a predetermined angle, and the torsion coil spring 24 (see fig. 3) attached to the fitting ring 22 is compressed. If the mating connector is pushed further in the fitting direction X, the torsion coil spring 24 biases the push claw 221 in a direction in which the push claw 221 enters the engagement region 145. By this urging force, the push-on claw 221 enters the engagement region 145, and the connector and the counterpart connector are locked in a fitted state (fig. 10D).

In the disengagement operation of the push-fit mechanism, the push-fit claw 221 is moved in the circumferential direction Y against the urging force of the torsion coil spring 24, and is disengaged from the engagement region 145 (fig. 10E). Thereafter, if the mating connector is pulled in the fitting-removal direction X', the push claw 221 can be moved along the 2 nd guide surface 142 of the push path 140 and removed from the 2 nd groove 144 (fig. 10F).

As described above, according to the connector of the present disclosure, the housing 10 including the push-on passage 140 and the bayonet passage 150 can be fitted appropriately with the push-on counterpart connector.

Next, fitting with the bayonet counterpart connector will be described below. Fig. 9B is a schematic diagram that enlarges the intersection of the push-on passage 140 and the bayonet passage 150 of the connector according to one embodiment of the present disclosure. As illustrated, the bayonet passages 150 are formed across the push-on passage 140, and may be continuous with each other at the crossing portions. As shown in fig. 13B, in this embodiment, a part of the guide surface of the bayonet claws 222 can be discontinuous, as compared with the conventional structure in which the guide surface of the bayonet claws 222 is continuous. That is, in the connector of the present disclosure, the bayonet passage 150 may include a plurality of guide surfaces that are intermittently formed.

In one embodiment, the connector of the present disclosure is provided with the 1 st guide surface 151 and the 2 nd guide surface 152 as 2 guide surfaces discontinuous via the push-on passage 140. That is, the guide surfaces of the bayonet passage 150 can be discontinuously formed on both sides of the push-on passage 140. The 1 st guide surface 151 and the 2 nd guide surface 152 may be configured as follows: when the connector of the present disclosure and the bayonet type plug connector are fitted, the bayonet claws 222 can first slide on the 2 nd guide surface 152 and then slide on the 1 st guide surface 151 to move. For example, as illustrated, the 1 st guide surface 151 of the bayonet passage 150 may be continuous with the 1 st guide surface 141 of the push-on passage 140 and extend in a direction different from the 1 st guide surface 141 of the push-on passage 140 at the intersection of the bayonet passage 150 and the push-on passage 140. On the other hand, the 2 nd guide surface 152 of the bayonet passage 150 may be continuous with the 2 nd guide surface 142 of the push-through passage 140, and may extend in a direction different from the 2 nd guide surface 142 of the push-through passage 140 at an intersection of the bayonet passage 150 and the push-through passage 140.

The bayonet passage 150 further includes a 3 rd guide surface 154 continuous from the 1 st guide surface 151. The 3 rd guide surface 154 may be also referred to as a guide inclined surface when inclined toward the fitting direction X (i.e., downward in the drawing) with respect to the circumferential direction Y of the housing. The housing 10 of the connector further includes an elongated ridge 153 spaced apart from and opposed to the 3 rd guide surface 154, and the bayonet passage 150 further includes a bayonet groove 155 formed between the elongated ridge 153 and the 3 rd guide surface 154. More specifically, the bayonet grooves 155 may be grooves in the form of recesses formed by the 3 rd guide surface 154, the elongated ridge 153, and the outer peripheral side surface of the housing 10 connecting the elongated ridge 153 to the 3 rd guide surface 154. The bayonet claws 222 are movable along the 1 st guide surface 151 and the 2 nd guide surface 152 of the bayonet passage 150, and are allowed to enter the bayonet grooves 155 and move along the 3 rd guide surface 154 and the elongated ridge 153 when the connector is fitted to and removed from the mating connector. That is, in the connector of the present disclosure, a part of the elongated protrusion 153 can also function properly as a guide of the bayonet claws 222 in addition.

In the side view shown in fig. 9B, 2 guide surfaces (the 1 st guide surface 151 and the 2 nd guide surface 152) may be located at different heights from each other. That is, the 1 st guide surface 151 and the 2 nd guide surface 152 may be disposed at positions offset from each other with respect to the fitting direction X. More specifically, the 1 st guide surface 151 of the 2 guide surfaces of the bayonet passage 150 may be relatively distant from the opening 130 of the housing, and the 2 nd guide surface 152 may be relatively close to the opening 130. In the related configuration, the bayonet claws 222 are movable from the 2 nd guide surface 152 toward the 1 st guide surface 151 during the fitting operation, and are appropriately movable from the 1 st guide surface 151 toward the 2 nd guide surface 152 during the disengaging operation.

In one embodiment, the opening side surface 161 of the protrusion 160 may be located between the 1 st guide surface 151 and the 2 nd guide surface 152 of the bayonet passage 150. That is, the 1 st guide surface 151 of the bayonet passage 150, the opening side surface 161 of the protrusion 160, and the 2 nd guide surface 152 of the bayonet passage 150 may be discontinuously arranged in the extending direction of the bayonet passage 150. In such a structure, the opening side surface 161 of the protrusion 160 is preferably disposed closer to the opening 130 side of the housing than the 1 st guide surface 151 of the bayonet passage 150. That is, the 1 st guide surface 151 of the bayonet passage 150 may be disposed offset from the opening side surface 161 of the protrusion 160 by a distance H1 in the fitting direction X (i.e., downward in the drawing). The distance H1 is not particularly limited as long as the bayonet claws 222 moving in the bayonet passage 150 can contact both the 1 st guide surface 151 of the bayonet passage 150 and the opening side surface 161 of the projection 160.

The opening side surface 161 of the protrusion 160 and the 1 st guide surface 151 of the bayonet passage 150 are configured as described above, so that the bayonet claws 222 can move toward the 1 st guide surface 151 after abutting against the opening side surface 161 of the protrusion 160 at the time of fitting operation of the connector (see fig. 11C). That is, the opening side surface 161 of the protrusion 160 can not only contribute to a stopper surface for preventing erroneous entry of the bayonet claws 222 into the push-through passage 140, but also contribute to a guide surface for the bayonet passage 150. Therefore, according to the above-described structure, a connector that can more appropriately correspond to either of the push-fit type and the bayonet type can be provided.

Further, the 2 nd guide surface 152 of the bayonet passage 150 may be disposed closer to the opening 130 of the housing than the opening side surface 161 of the protrusion 160. That is, the 2 nd guide surface 152 of the bayonet passage 150 may be disposed offset from the opening side surface 161 of the protrusion 160 by a distance H2 in the fitting-disengaging direction X' (i.e., upward in the drawing). The distance H2 is not particularly limited as long as the bayonet claws 222 moving in the bayonet passage 150 can contact both the 2 nd guide surface 152 and the opening side surface 161 of the bayonet passage 150.

The opening side surface 161 of the protrusion 160 and the 2 nd guide surface 152 of the bayonet passage 150 are configured as described above, so that, during the fitting operation of the connector, the bayonet claws 222 can be moved along the 2 nd guide surface 152 of the bayonet passage 150, then come into contact with the opening side surface 161 of the protrusion 160, and thereafter, move in the fitting direction X toward the 1 st guide surface 150 so as to be inclined with respect to the circumferential direction Y (see fig. 11B). Likewise, in the disengagement fitting operation, the bayonet claws 222 can be appropriately disengaged from the bayonet passage 150 by moving from the 1 st guide surface 151 toward the opening side surface 161 and the 2 nd guide surface 152.

In a suitable embodiment, the 1 st guide surface 151 and the 2 nd guide surface 152 of the bayonet passage 150 and the opening-side contact surface 161 of the protrusion 160 are arranged parallel to each other and offset from each other. More preferably, the 1 st guide surface 151 and the 2 nd guide surface 152 of the bayonet passage 150 and the opening-side contact surface 161 of the protrusion 160 may be offset in parallel with each other along the circumferential direction Y of the housing 10. That is, the movement direction of the bayonet claws 222 may be inclined with respect to the circumferential direction Y of the housing 10, while the 1 st guide surface 151 and the 2 nd guide surface 152 of the bayonet passage 150 and the opening-side contact surface 161 of the projection 160 may extend along the circumferential direction Y of the housing 10. On the other hand, as described above, the 3 rd guide surface 154 forming the bayonet groove 155 extends obliquely with respect to the circumferential direction Y of the housing 10. Therefore, the 1 st guide surface 151 and the 2 nd guide surface 152 of the bayonet passage 150 and the opening-side contact surface 161 of the protrusion 160 can extend in different directions from the 3 rd guide surface 154 of the bayonet passage 150.

In the case where the above-described 3 surfaces with which the bayonet claws 222 come into contact are inclined with respect to the circumferential direction Y along the moving direction of the bayonet claws 222, the bayonet passage 150 from the 1 st guide surface 151 to the 2 nd guide surface 152 inevitably becomes longer. In the connector of the present disclosure, the 1 st guide surface 151 and the 2 nd guide surface 152 and the opening-side abutment surface 161 of the protrusion 160 are both surfaces extending in the circumferential direction Y, thereby realizing a shorter bayonet passage 150. Therefore, according to the above-described configuration, it is possible to provide a connector that is more suitable from the viewpoints of miniaturization of the connector and efficiency of the fitting/fitting-out operation.

Fig. 11A to 11E are schematic expanded views illustrating movement of the bayonet claws 222 in the connector according to an embodiment of the present disclosure. As illustrated, the connector and the counterpart connector may be combined in such a way that the bayonet claws 222 abut against the 2 nd guide surface 152 of the bayonet passage 150 (fig. 11A). Next, when the mating connector fitting ring 22 (see fig. 6) is rotated, the bayonet claws 222 move along the 2 nd guide surface 152 and come into contact with the opening side surfaces 161 of the protrusions 160 (fig. 11B). If the fitting ring 22 is further rotated, the bayonet claws 222 move along the opening side surface 161 toward the 1 st guide surface 151 of the bayonet passage 150 (fig. 11C). Thereafter, with further rotation of the fitting ring 22, the bayonet claws 222 move along the 1 st guide surface 151 and enter the bayonet grooves 155 defined by the 3 rd guide surface 154 and the elongated ridge 153.

The elongated ridge 153 can help guide movement of the bayonet catch 222 within the bayonet slot 155. When the bayonet claws 222 enter the bayonet grooves 155 from the opening 130 side of the housing, the opening side end 153a of the long bulge portion 153 located on the opening 130 side of the housing can guide the bayonet claws 222 moving from the 2 nd guide surface 152 side toward the 1 st guide surface 151 into the bayonet grooves 155.

As shown in fig. 12A and 12B, the opening-side end 153a may be located further in the fitting-disengaging direction X' (i.e., upward in the drawing) than the 2 nd guide surface 152 by a distance H3, the distance H3 being larger than the thickness dimension Tb of the tip 222A of the bayonet claw 222 on the entry direction side of the bayonet groove 155. In other words, the 2 nd guide surface 152 may be located closer to the fitting direction X (i.e., downward in the drawing) than the opening-side end 153a by a distance H3, and the distance H3 may be larger than the thickness dimension Tb of the tip 222a of the bayonet claw on the entry direction side of the bayonet groove 155. That is, the width H3 between the virtual extension surface of the 2 nd guide surface 152 in the longitudinal extension direction (for example, the circumferential direction of the housing) and the opening-side end 153a of the elongated ridge 153 may be larger than the thickness Tb of the tip 222a of the bayonet claw toward the entry direction side of the bayonet passage 150. According to the structure, the bayonet claws 222 moving along the 2 nd guide surface 152 can be more appropriately guided into the bayonet grooves 155.

The bayonet claws 222 that have passed through the bayonet grooves 155 can be locked by abutting against the protrusions 160 (fig. 11D and 11E). That is, in the connector of the present disclosure, the protrusion 160 can also contribute to the locking of the bayonet claws 222. The protrusion 160 may have an engagement surface 162 that can engage the bayonet claws 222. The engagement surface 162 is a side surface of the protrusion 160 opposite to the opening side surface 161. The bayonet claws 222 pass through the bayonet grooves 155 and enter the intersecting portions with the push-on paths 140, and then are locked to the locking surfaces 162 of the protrusions 160, whereby the connector and the counterpart connector are held in a fitted state. That is, in the fitting operation of the connector of the present disclosure and the bayonet counterpart connector, the fitting ring is rotated until the bayonet claws 222 are locked to the locking surfaces 162 of the protruding portions 160, so that the fitted state can be maintained.

In some suitable arrangement, the catch surface 162 is in complementary relationship to a portion of the profile surface of the bayonet catch 222. More specifically, the engagement surface 162 preferably has a complementary relationship with a contour surface that abuts against the engagement surface 162 at the bayonet claws 222. As described above, the bayonet claws 222 may be inclined with respect to the circumferential direction Y of the housing 10 so as to be complementary to the bayonet passage 150 (in the connector of the present disclosure, the bayonet groove 155). The engagement surface 162 may engage the bayonet claws 222 with the inclined surfaces of the bayonet claws 222. In this case, the locking surface 162 may be a surface inclined in the same manner as the inclined surface of the bayonet claws 222. In this way, the engagement surface 162 and a part of the contour surface of the bayonet claw 222 are in a complementary relationship, so that the engagement surface 162 can be in surface contact with the bayonet claw 222, and the bayonet claw 222 can be more appropriately engaged.

In the locked state of the bayonet claws 222, the bayonet claws 222 preferably contact both the locking surface 162 of the protrusion 160 and the elongated ridge 153. That is, in the locked state (i.e., the fitted state), the bayonet claws 222 may have one end in contact with the locking surface 162 and the other end in contact with the elongated ridge 153 defining the bayonet groove 155. This can prevent the bayonet claws 222 from moving in the fitting-disengaging direction X' by the push-on passage 140, and can appropriately lock the bayonet claws 222. Further, in the locked state, the bayonet claws 222 contact the elongated protrusions 153, so that the bayonet claws 222 can be smoothly guided to the bayonet grooves 155 when the fitting operation is released.

The connector of the present disclosure may include a plurality of combinations of the push passage 140 and the bayonet passage 150. Preferably, at least 2 may be provided on the outside of the housing 10 of the connector of the present disclosure facing the combination of the push-on passage 140 and the bayonet passage 150. Thus, in the case of adopting either the bayonet type or push type fitting method, the claws of the connector and the counterpart connector of the present disclosure are locked at a plurality of positions, and thus the fitted state can be more appropriately maintained.

As shown in fig. 8, in the case where the housing 10 of the connector includes a plurality of push-on passages 140, the bayonet passages 150 may be formed across 2 push-on passages 140 that are isolated from each other and adjacent to each other. In the solution concerned, the bayonet slot 150 may extend from one push channel 140 to the other push channel 140 of the mutually adjoining push channels 140. That is, one end side of the bayonet passage 150 may be located in one push passage 140 among the mutually adjacent push passages 140, and the other end side of the bayonet passage 150 may be located in the other push passage 140. In such a configuration, as shown in fig. 11A to 11E, 1 bayonet claw 222 may be able to contact 2 different protrusions. More specifically, the bayonet claws 222 are movable along the bayonet grooves 155 from the opening side surfaces 161 of the protruding portions 160 of one push-in passage 140, and are capable of being locked to the locking surfaces 162 of the protruding portions 160 of the other push-in passage 140.

The connector of the present disclosure may further include a screw-type fitting mechanism in addition to the combination of the push-on passage 140 and the bayonet passage 161. More specifically, the connector housing 10 may further include a male screw 170 that can be fastened to a female screw provided in the mating ring 22 of the mating connector. According to the structure, the connector of the present disclosure can correspond to a screw-type fitting manner in addition to a push-type and a bayonet-type.

The male screw 170 may be formed at the outer circumferential surface of the housing 10. For example, as in the case 10B shown in fig. 13B, the male screw 170 may be provided in a region different from the push-through passage 140 and the bayonet passage 150. Preferably, the male screw 170 may be formed to cross the push passage 140 and/or the bayonet passage 150. In such a configuration, the push passage 140 and/or the bayonet passage 150 may be formed by cutting out a part of the male screw 170 formed on the outer peripheral surface of the housing 10. In this way, the connector can be further miniaturized by forming a structure in which the fitting modes partially intersect.

While the embodiments of the present disclosure have been described above, the present disclosure is not limited thereto, and various modifications such as combining the above-described components based on the knowledge of those skilled in the art can be made without departing from the spirit of the claims.
