Description

  The present invention relates to a connector and a male connector used therefor, and more specifically, includes a female connector having a female terminal and a male connector having a male terminal, and the male terminal is connected to the female connector by joining the male connector to the female connector. The present invention relates to a connector for electrical connection and a male connector used therefor.

  Patent Literature 1 discloses a female housing including a hood portion into which a male housing is inserted and fitted, and a cover fitted to the outer peripheral surface of the hood portion. The cover of the female housing is formed of a resin material that is harder than the hood portion. A plurality of protrusions are provided on the inner peripheral surface of the cover. These protrusions are pressed against the outer peripheral surface of the hood portion when the cover is fitted to the hood portion. Thereby, since the cover can be attached to the hood portion without rattling, rattling of the female housing relative to the male housing can be suppressed.

  Thus, in patent document 1, a female housing is formed from a member with different intensity | strength, and a protrusion is provided between these different members, and it is made to fit. This suppresses rattling of the female housing while ensuring the strength of the female housing, and prevents sliding wear between the female terminal and the male terminal, and consequently, poor electrical conduction between the female terminal and the male terminal. Yes.

  Incidentally, the connector as described above may be used as means for transmitting the output of a sensor mounted on a vehicle such as a motorcycle to an ECU (electronic control unit) of the vehicle. In this case, while a general-purpose female connector manufactured by a connector manufacturer is used on the vehicle side, a male connector manufactured by a sensor manufacturer is often used on the sensor side. Furthermore, in this case, the sensor in which the male connector is integrally formed is fixed to a specific part of the vehicle so as to detect information related to the vehicle.

  On the other hand, the electrical wiring connected to the female terminal is often drawn out from the female connector. Therefore, since the female housing is likely to rattle due to vibration during traveling of the vehicle, when using a general-purpose female connector on the vehicle side that does not take measures to suppress rattling, it is integrated with the sensor. In the male connector, it is desirable to take measures for suppressing the rattling of the female housing.

  Specifically, it is conceivable to provide a protrusion as described in Patent Document 1 on the outer peripheral surface of the male housing to suppress the rattling of the female housing. Moreover, in order to suppress the shakiness of the female housing more effectively, it is conceivable to provide a plurality of protrusions on the outer peripheral surface of the male housing. Alternatively, it is conceivable that the fitting of the male housing to the female housing is approximately the same as the interference fitting, and the female housing and the male housing are firmly fitted. However, even if these measures are taken, when the male housing is inserted and assembled into the female housing, the projection of the male housing is excessively pressed against the female housing, and stress may concentrate on the projection, and the male housing may be deformed. It cannot be excluded.

  Such deformation of the male housing increases the insertion load of the male housing that is generated when the male housing is inserted into the female housing, and thus there is a possibility that the assembling property of the connector is deteriorated. Further, the male housing or the female housing may be damaged due to the stress concentration generated in the protrusion or the excessive insertion load generated in the male housing.

  Therefore, similarly to the female housing described in Patent Document 1, the male housing is formed of members having different strengths to partially increase the strength, and protrusions are provided between these different members to suppress rattling of the female housing. It is possible. For example, if the protrusion is formed of an elastic member such as rubber different from the male housing, it is possible to reduce both the stress concentration generated in the protrusion and the insertion load of the male housing while suppressing the rattling of the female housing. Is possible.

  However, when the male housing is formed from a plurality of members, the material cost of the male connector increases, the manufacturing process of the male connector becomes complicated, and the manufacturing cost of the male connector increases.

  The present invention has been made in view of such problems, and the object of the present invention is to suppress rattling of the female housing, reduce stress concentration generated in the male housing, and insertion load when the male housing is assembled. Terminal wear and terminal damage due to sliding between terminals can be suppressed at a low cost by using a male connector that can reduce all of the manufacturing costs and reduce the manufacturing cost of the male housing. An object of the present invention is to provide a connector capable of preventing poor conduction between terminals due to damage, and a male connector used therefor.

  In order to achieve the above object, the connector of the present invention comprises a male connector having a first terminal and a female connector having a second terminal, and the first terminal by connecting the male connector to the female connector. The male connector has a cylindrical male housing that surrounds the periphery of the first terminal, and the female connector surrounds the periphery of the second terminal. The male housing has a cylindrical female housing into which the male housing is inserted and fitted, and the male housing is in contact with the inner peripheral surface of the female housing in a state where the male housing is fitted to the female housing. And one or more protrusions integral with the.

Preferably, the plurality of protrusions have a protrusion height that is increased in order from the opening side of the male housing.
Preferably, the female connector holds the second terminal and forms a gap that allows insertion of the male housing between the female housing, an inner peripheral surface of the male housing, and an outer peripheral surface of the columnar portion. And an annular seal member positioned in the vicinity of the opening of the male housing.

Preferably, the protrusion has an abutting surface that is convexly curved toward the inner peripheral surface of the female housing.
Preferably, the projection forms a ridge extending along the circumferential direction of the outer peripheral surface of the male housing.
Preferably, the male housing has at least one set of facing surfaces forming an outer peripheral surface, and the protrusions are provided on at least one set of facing surfaces, respectively.

Preferably, the female connector is provided in a motorcycle vehicle.
Preferably, the male connector is provided in a sensor that detects information related to the vehicle.
The male connector of the present invention includes a first terminal and a cylindrical male housing surrounding the first terminal, and the male connector is connected to the female connector having the second terminal, A male connector that constitutes a connector by electrically connecting a second terminal to a first terminal, and the female connector surrounds the periphery of the second terminal, and is a cylinder into which a male housing is inserted and fitted The male housing has one or more protrusions integral with the male housing that contacts the inner peripheral surface of the female housing in a state of being fitted to the female housing on the outer peripheral surface thereof.

  According to the connector of the present invention and the male connector used therefor, suppression of rattling of the female housing, reduction of stress concentration generated in the male housing, reduction of insertion load when assembling the male housing, and manufacturing cost of the male housing By using a male connector that can achieve all the reductions, terminal wear and terminal damage caused by sliding between terminals can be suppressed at a low cost, and consequently conduction failure between terminals caused by such terminal wear and terminal damage.

FIG. 1 is a perspective view of a sensor 2 connected to a motorcycle vehicle (not shown) via a connector 1. The sensor 2 is, for example, a composite sensor module in which a plurality of sensors such as a non-contact throttle position sensor, an intake air temperature sensor, and a pressure sensor are packaged, and detects information related to the vehicle. The connector 1 includes a female connector 10 disposed on the vehicle side, and a male connector 30 formed integrally with the sensor body 2a of the sensor 2. In FIG. 1, the female connector 10 and the male connector 30 are not connected.

  Electrical wirings 4 connected to a plurality of female terminals (second terminals) 12 to be described later of the female connector 10 are led out from the vehicle-side rear surface 10a of the female connector 10, respectively. These electric wires 4 are bundled to form one cable 6, and this cable 6 is electrically connected to an ECU (electronic control unit) (not shown) of the vehicle. Thereby, the output of the sensor 2 is transmitted to the ECU and used as information for driving the vehicle.

  FIG. 2 is a front view of the female connector 10 as viewed from the front side where the female connector 10 is connected to the male connector 30. The female connector 10 includes a plurality of female terminals 12 and a female housing 14 that surrounds each female terminal 12. The female terminal 12 is formed in a socket shape from a conductive metal material. The female housing 14 is formed of a resin material or the like into a bottomed cylindrical shape having a quadrangular cross section, and has a cylindrical bottom 14a, an opening 14b, an inner peripheral surface 14c, and an outer peripheral surface 14d.

  A columnar portion 16 is integrally projected from the tube bottom 14a of the female housing 14 toward the opening 14b by resin molding. The periphery of each female terminal 12 is embedded in the columnar portion 16. The columnar portion 16 holds each female terminal 12 and forms a gap 35 between the female housing 14 and a male housing 34 described later. From the columnar portion 16, the socket opening 12 a of each female terminal 12 is exposed on the opening 14 b side of the female housing 14.

  The inner peripheral surface 14c of the female housing 14 includes an upper surface 14c1 on the upper side as viewed in FIG. On the upper surface 14 c 1, two guide grooves 18 extend in the cylinder height direction of the female housing 14, in other words, in the insertion direction X of the male housing 34 with respect to the female housing 14. Two guides 36 described later of the male housing 34 are respectively positioned in the respective guide grooves 18.

  A locking portion 20 is formed between the two guide grooves 18 on the upper surface 14 c 1 of the inner peripheral surface 14 c of the female housing 14. A locking claw 38 (to be described later) of the male housing 34 is locked to the locking portion 20. A seal member 22 is mounted on the outer peripheral surface 16 a of the columnar portion 16 in the vicinity of the cylinder bottom 14 a of the female housing 14, that is, at the root of the columnar portion 16.

  FIG. 3 is a perspective view of the seal member 22. The seal member 22 is an annular belt-shaped waterproof packing formed from an elastic member such as a resin material, and is attached to the outer peripheral surface 16a of the columnar portion 16 with the width direction of the seal member 22 as the insertion direction X described above. On the outer peripheral surface of the sealing member 22, a plurality of convex annular sealing portions 22 a are formed side by side in the width direction of the sealing member 22.

  4 is a perspective view of the male connector 30, FIG. 5 is a front view of the male connector 30 as viewed from the front for connecting the female connector 10 to the female connector 10, and FIG. 6 is a side view of the male connector 30. The male connector 30 includes a plurality of male terminals (first terminals) 32 and a male housing 34 that surrounds each male terminal 32. The male terminal 32 is formed in a pin shape from a conductive metal material. The male housing 34 is formed of a resin material or the like into a bottomed cylindrical shape having a quadrangular cross section, and has a cylindrical bottom 34a, an opening 34b, an inner peripheral surface 34c, and an outer peripheral surface 34d. Each male terminal 32 protrudes from the cylinder bottom 34a of the male housing 34 toward the opening 34b.

  4 to 6, the outer peripheral surface 34d of the male housing 34 includes an upper surface 34d1 and a lower surface 34d2 that constitute one set of upper and lower opposing surfaces, and a side surface 34d3 that constitutes another set of left and right opposing surfaces, 34d3. Two guides 36 are extended on the upper surface 34 d 1 of the male housing 34 in the cylinder height direction of the male housing 34, that is, in the insertion direction X. On the upper surface 34 d 1 of the male housing 34, locking claws 38 project between the guides 36.

  FIG. 7 is a cross-sectional view of the connector 1 showing a connection state between the female connector 10 and the male connector 30. When connecting the male connector 30 to the female connector 10, first, the corresponding guide 36 of the male housing 34 is matched with each guide groove 18 of the female housing 14. Then, the male housing 34 is inserted into the female housing 14 in the insertion direction X until the locking claw 38 of the male housing 34 is caught by the locking portion 20 of the female housing 14.

  Thereby, the male housing 34 is fitted to the female housing 14. At this time, the locking claw 38 is locked to the locking portion 20, so that the male housing 34 is prevented from coming off from the female housing 14. Further, the fitting of the male housing 34 to the female housing 14 is desirably an intermediate fitting degree that allows the male housing 34 to be attached to and detached from the female housing 14.

  In the state of FIG. 7, the seal member 22 is positioned between the inner peripheral surface 34 c of the male housing 34 and the outer peripheral surface 16 a of the columnar portion 16 and in the vicinity of the opening 34 b of the male housing 34. At this time, each seal portion 22 a of the seal member 22 comes into contact with the inner peripheral surface 34 c of the male housing 34. As a result, intrusion of water or foreign matter into the inside of the connector 1 and, in turn, an electrical short circuit between the female terminal 12 and the male terminal 32 due to these intrusions are prevented.

With such connection between the female connector 10 and the male connector 30, the male terminal 32 is inserted into the socket opening 12a of the female terminal 12, and the female terminal 12 and the male terminal 32 are electrically connected.
Here, in this embodiment, as shown in FIGS. 4 to 6, the protrusions 40 and 42, the protrusions 44 and 46, and the protrusions 48 and 48 are integrally formed on the outer peripheral surface 34 d of the male housing 34 by resin molding. Is formed.

  The protrusions 40 and 42 are arranged at two positions along the insertion direction X on the upper surface 34d1 of the outer peripheral surface 34d. The protrusion 40 is positioned in the vicinity of the opening 34 b of the male housing 34. On the other hand, the protrusion 42 is positioned on the cylinder bottom 34 a side of the male housing 34. In the case of this embodiment, the protrusions 40 and 42 are provided on both sides of the two guides 36 and the locking claws 38, respectively, and are integrally molded with the guide 36. Further, the protrusions 40 and 42 have protrusions extending along the circumferential direction of the outer peripheral surface 34d, that is, elongated protrusions.

  The protrusions 44 and 46 are arranged in the insertion direction X on the lower surface 34d2 of the outer peripheral surface 34d. The protrusion 44 is positioned on the opening 34 b side of the male housing 34. On the other hand, the protrusion 46 is positioned on the cylinder bottom 34 a side of the male housing 34. In the case of this embodiment, the protrusions 44 and 46 form a protrusion longer than the protrusions 40 and 42 described above, and extend along the circumferential direction of the outer peripheral surface 34d. Further, the protrusions 44 and 46 are disposed at substantially the same positions as the protrusions 40 and 42 in the vertical direction Y of FIGS.

The protrusions 48 and 48 are formed on both side surfaces 34d3 and 34d3 of the outer peripheral surface 34d, respectively. In the case of this embodiment, each protrusion 48 forms a protrusion that extends along the insertion direction X.
As shown in FIG. 6, the protrusion 40 has a protrusion height H1 (for example, 0.2 mm), and the protrusion 42 has a protrusion height H2 (for example, 0.3 mm) that is larger than H1.

Further, the protrusion 44 has the same protrusion height H1 as the protrusion 40, and the protrusion 46 has the same protrusion height H2 as the protrusion 42. That is, the protrusion heights of the protrusions 40 and 42 and the protrusions 44 and 46 are gradually increased from the opening 34b side of the male housing 34 in order.
As shown in FIG. 5, each of the protrusions 48 has a protrusion height H3 (for example, 0.3 mm).

  FIG. 8 is a perspective view of the protrusion 40. The protrusion 40 is formed to have a contact surface 40 a that is convexly curved toward the inner peripheral surface 14 c of the female housing 14. In addition, although illustration is abbreviate | omitted, the other protrusions 42-48 also have the contact surface similar to the contact surface 40a.

  As described above, in the present embodiment, the outer peripheral surface 34 d of the male housing 34 has the protrusions 40 to 48 that are resin-molded integrally with the male housing 34. Thereby, the protrusions 40 to 48 of the male housing 34 formed of a single member can be brought into contact with the inner peripheral surface 14 c of the female housing 14. Therefore, for example, even when using a general-purpose female connector 10 for which measures for suppressing rattling are not used on the vehicle side, while reducing the manufacturing cost of the male housing 34, The rattling of the female housing 14 can be suppressed on the male connector 30 side.

  Further, on the upper surface 34d1 of the outer peripheral surface 34d of the male housing 34, protrusions 40 and 42 are provided on both sides of the two guides 36 and the locking claws 38 in the insertion direction X, respectively. In addition, protrusions 44 and 46 are arranged in the insertion direction X on the lower surface 34 d 2 of the outer peripheral surface 34 d of the male housing 34. Thereby, the rattling in the vertical direction Y of the female housing 14 with respect to the male housing 34 can be effectively suppressed over a wide range of the upper surface 34d1 and the lower surface 34d2 of the outer peripheral surface 34d of the male housing 34.

  Further, the upper surface 34d1 and the lower surface 34d2 of the outer peripheral surface 34d of the male housing 34 are provided with protrusions 40 and 42 and protrusions 44 and 46 respectively positioned on both sides of the two guides 36 and the locking claws 38. Yes. Thereby, compared with the case where these protrusions 40 and 42 and protrusions 44 and 46 are formed as one protrusion without being divided, the stress generated in the protrusions 40 to 46 can be relaxed. Therefore, the deformation of the male housing 34 based on the stress concentration generated in the protrusions 40 to 46 can be suppressed.

  Further, the protrusion heights H1 and H2 of the protrusions 40 and 42 and the protrusion heights H1 and H2 of the protrusions 44 and 46 are sequentially increased from the opening 34b side of the male housing 34, so The insertion load when inserting and fitting can be reduced.

  FIG. 9 shows, as a comparative example, a stress analysis result of the male housing 34 when the protrusion height H1 of the protrusions 40 and 44 is equal to or higher than the protrusion height H2 of the protrusions 42 and 46. In FIG. 9, the magnitude of the stress is expressed by gradation so that the black color is thin when the stress generated in the male housing 34 is large and the black color is dark when the stress is small. As shown by a thin gradation in FIG. 9, when the male housing 34 is inserted and fitted into the female housing 14, stress concentration occurs in the vicinity of the opening 34 b of the male housing 34.

  That is, in the case of FIG. 9, it can be seen that the insertion load in the vicinity of the opening 34 b of the male housing 34 is increased as compared with other parts of the male housing 34. Such an increase in insertion load is caused by the protrusions 40 and 44 having an excessive protrusion height H1 pressing the vicinity of the opening 34b of the male housing 34 in the vertical direction indicated by the arrow by the female housing 14, and the male housing 34 is deformed. As a result, the insertion space of the male housing 34 in the gap 35 in which the seal member 22 is disposed is narrowed.

  Further, due to such a narrow insertion space of the male housing 34, the seal member 22 is excessively pressed against the male housing 34 when the male housing 34 is inserted into the female housing 14. As a result, the repulsive force of the seal member 22 that is excessively pressed acts on the male housing 34, causing further deformation of the male housing 34 and further increase in insertion load.

  However, in the present embodiment, even when the seal member 22 is disposed in the vicinity of the opening 34b of the male housing 34, the protrusion height H1 of the protrusions 40 and 44 on the opening 34b side of the male housing 34 is protruded as described above. The insertion load of the male housing 34 with respect to the female housing 14 can be effectively reduced by making it slightly lower than the protrusion height H2 of 42 and 46.

  In addition, since the seal member 22 is not excessively pressed by the insertion of the male housing 34, it is possible to avoid the deformation accompanying the plastic deformation of the seal member 22, and as a result, the seal due to the deterioration of the seal member 22. Performance degradation can also be suppressed.

  FIG. 10 shows an analysis result of stress generated in the male housing 34 of the present embodiment having the protrusions 40 to 48. In FIG. 10, the magnitude of the stress is expressed by gradation so that the black color is dark when the stress generated in the male housing 34 is large and the black color is thin when the stress is small. As is apparent from FIG. 10, in this embodiment, when the male housing 34 is inserted and fitted into the female housing 14, the protrusions 40 and 44 located near the opening 34 b of the male housing 34 are at least excessively large. There is no stress concentration.

  The excessive stress concentration does not occur in the protrusions 40 and 44 because the protrusion height H1 of the protrusions 40 and 44 is reduced, so that the insertion space of the male housing 34 in the gap 35 in which the seal member 22 is disposed is secured. This is because the insertion load of the male housing 34 is reduced.

  Further, the protrusions 40 to 48 have a contact surface 40 a that is convexly curved toward the inner peripheral surface 14 c of the female housing 14. Thereby, it can prevent that excessive stress concentration generate | occur | produces in protrusion 40-48. Therefore, rattling of the female housing 14 can be effectively suppressed while suppressing deformation and breakage of the male housing 34. Although illustration is omitted, when the contact surfaces having edges are formed on the protrusions 40 to 48 or when the protrusions 40 and 42 are formed as continuous integral protrusions, excessive stress concentration on the protrusions. Has been found to occur.

  Further, the fact that the protrusions 40 and 44 form protrusions extending along the circumferential direction of the outer peripheral surface 34d of the male housing 34 also contributes to the relaxation of the stress concentration. The protrusions 40 and 44 of such ridges effectively suppress the rattling of the female housing 14 in a wide pressing area, and the stress generated in the protrusions 40 and 44 and the insertion of the male housing 34 into the female housing 14. This is because both the load and the load can be effectively reduced.

  As shown in FIG. 10, at least a certain amount of stress is generated in the protrusions 42, 46, 48 located outside the vicinity of the opening 34 b of the male housing 34. That is, the connector 1 of the present embodiment has a so-called fitting function for firmly fixing the male housing 34 to the female housing 14 on the protrusions 42, 46, and 48.

  On the other hand, the protrusions 40 and 44 have only a support function to prevent the male housing 34 inserted into the female housing 14 from swinging around the protrusions 42 and 44. In the present embodiment, the protrusions 40 to 48 having different functionalities are integrally provided on the male housing 34, thereby suppressing the rattling of the female housing 14 while reducing the manufacturing cost of the male housing 34. A reduction in the concentration of generated stress and a reduction in insertion load when the male housing 34 is assembled are realized at the same time.

FIG. 11 shows the surface of the male terminal 32 after a vibration test of the connector 1 having the male housing 34 having no protrusions 40 to 48 as a comparative example. A wear scar 32 a is formed on the surface of the male terminal 32 by sliding with the female terminal 12.
FIG. 12 shows in time series the output of the sensor 2 when the connector 1 having the male terminal 32 of FIG. 11 is energized. As is apparent from FIG. 12, when the wear scar 32 a is formed on the male terminal 32, a large number of noises are formed in the output waveform of the sensor 2, and abnormality is seen in the output of the sensor 2.

On the other hand, FIG. 13 shows the surface of the male terminal 32 after the vibration test of the connector 1 including the male housing 34 of the present embodiment having the protrusions 40 to 48. On the surface of the male terminal 32, no noticeable wear scar 32a as shown in FIG.
FIG. 14 shows in time series the output of the sensor 2 when the connector 1 having the male terminal 32 of FIG. 13 is energized. As apparent from FIG. 14, no noise is confirmed in the output waveform of the sensor 2, and the output of the sensor 2 is normal. In addition, the vibration test which obtained the result of FIG. 13, FIG. 14 is performed on the same conditions as the vibration test which obtained the result of FIG.

As is apparent from the results of the vibration tests in FIGS. 11 to 14, in the connector 1 including the male housing 34 of the present embodiment, the rattling of the female housing 14 is suppressed. Thus, terminal wear and terminal damage due to sliding and the like, and consequently conduction failure between the female terminal 12 and the male terminal 32 due to terminal wear and terminal damage can be reliably prevented.
This is the end of the description of the embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the present invention.

For example, in the present invention, it is only necessary to have one or more protrusions integral with the male housing 34 that contacts the inner peripheral surface 14c of the female housing 14, and the above-described protrusion 40 to 48 is formed in the form of the male housing 34. It is not limited.
Specifically, in the above embodiment, the male housing 34 has a quadrangular bottomed cylindrical shape, and two sets of opposing surfaces forming the outer peripheral surface 34d, that is, the upper surface 34d1 and the lower surface 34d2, and the side surface 34d3. , 34d3.

  When the projections 40 to 48 are provided on the two opposing surfaces of the male housing 34, the female housing 14 rattles due to both vertical and horizontal vibrations applied to the connector 1. Can be effectively suppressed. However, the present invention is not limited to this, and the protrusion of the male housing 34 may be provided with at least one protrusion considering the protrusion height on at least one pair of opposing surfaces of the male housing 34. In this case, rattling of the female housing 14 due to vibration acting in the opposing direction of the pair of opposing surfaces can be suppressed at least.

  The male housing 34 may have a shape other than a quadrilateral cross section, or the male housing 34 may be formed of a material having flexibility. In these cases, the back of the female housing 14 is not limited to one set of opposing surfaces constituting the outer peripheral surface 34d of the male housing 34, but if one or more protrusions are formed on at least one surface of the outer peripheral surface 34d. In some cases, it is possible to suppress sticking.

  Moreover, although it is preferable that the protrusions 40 to 48 have a shape having a contact surface 40a, it is not always necessary to have a protrusion, that is, an elongated protrusion. For example, depending on the shape and material of the male housing 34, it may be possible to suppress the rattling of the female housing 14 only by forming a protrusion that is a partially raised protrusion.

  Moreover, in the connector 1 of the said embodiment, the female connector 10 is provided in the vehicle of a motorcycle, and the male connector 30 is provided in the sensor 2 which detects the information regarding a vehicle.
