Description

[Technical field]

[0001] The present invention relates to a connector, and more particularly to a technique for fitting housings together in a lever-type connector. [Background technology]

[0002] Lever-type connectors have been known in the industrial field as connectors for connecting male and female terminals. By using these lever-type connectors, workers can easily connect, for example, an in-vehicle harness to an in-vehicle device on-site.

[0003] In a typical lever-type connector, one housing houses multiple male terminals and the other housing houses multiple female terminals. By rotating a lever provided on one of the housings, the two housings are attracted to each other and mated together. As a result, the male and female terminals are electrically connected well.

[0004] As mentioned above, the mating work of the two housings (connecting the male and female terminals) is generally performed by workers at the site, such as in a factory. In other words, the on-site environment is not necessarily suitable for mating work of lever-type connectors. For example, there may be cases where it is difficult to visually confirm the lever-type connector or where it is difficult to attach the housings to each other.

[0005] Therefore, in order to minimize operational errors, it is common to first bring the housings into contact (attach) with each other to form a temporary mating state, and then rotate the lever to finally mate the two housings (electrically connect the male and female terminals).

[0006] On the other hand, if the position of the lever and the relative positions of the housings are correct (also called the correct posture), proper fitting work can be performed. However, for example, if the relative positions of the housings are deviated or tilted from the correct posture during temporary fitting, there is a risk of the housings being improperly fitted together (such as the housings not being fully fitted together, or the terminals not being connected properly or at all).

[0007] Therefore, Patent Document 1 discloses a technology in which a regulating protrusion (a convex portion for filling a gap) is formed on a lever-type connector that joins a male housing and a female housing, and the regulating protrusion is abutted against the outer edge of the tip of a terminal accommodating portion of the female housing under specified conditions, thereby regulating the tilt of the posture between the female housing and the male housing.

[0008] Patent document 2 also discloses technology relating to a lever-type connector that includes a housing that can be mated with a mating connector, and a lever that is attached to the housing and draws the mating connector and the housing together by moving from a temporary locking position to a full locking position, and that utilizes an elastically deformable temporary locking arm on the lever (by constantly pressing the elastically deformable temporary locking arm against the sliding surface of the housing) to suppress inclination of the lever's pivot axis. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] JP 2016-96094 A [Patent Document 2] JP 2018-186030 A Summary of the Invention [Problem to be solved by the invention]

[0010] As described above, by providing a restricting protrusion on a lever-type connector using the technology of Patent Document 1, it is possible to suppress tilting of the posture between the female housing and the male housing. However, the technology of Patent Document 1 reduces the amount of gap (clearance) on the assumption that there will be a gap when mating, that is, a certain amount of gap remains. Therefore, for example, when mating the two housings by rotating the lever, the position of the female housing and the male housing may be shifted due to the rotation of the lever, and as a result, the above-mentioned mis-mating may occur.

[0011] In addition, the use of an elastically deformable provisional locking arm as in Patent Document 2 can suppress the inclination of the lever's rotation axis, but the configuration of Patent Document 2 is only capable of fixing the inclination of the lever's rotation axis, i.e., the position of the rotation axis. On the other hand, when housings are mated using a lever-type connector, mismatching often occurs due to the fact that both housings are misaligned or tilted around the lever's rotation axis. In other words, the technologies of Patent Documents 1 and 2 alone are not sufficient to prevent mismatching (such as a state in which the housings are not fully mated, or a state in which the terminals are not fully connected or not connected at all), and there is still room for improvement.

[0012] The present invention has been made in consideration of the problems with the prior art described above, and its object is to provide a lever-type connector that has a simple configuration that can prevent the housings from tilting together when mated, and that can reduce the force required to rotate the lever.

The circular cam convex portion has a plurality of convex portions on a circular cam. At approximately the center position in the longitudinal direction of the connect-side housing, a substantially rectangular plate-shaped boss guide plate having a plurality of cam grooves with which the circular cam convex portion meshes like a gear is provided. The boss guide plate has a boss opening portion into which the boss can enter in the direction in which the base-side housing and the connect-side housing are fitted together, and also has a temporary fitting guide groove that extends linearly toward the cover portion. The temporary fitting guide groove is connected to a main fitting guide groove that extends linearly in the direction in which the operation portion is located at the time of the main fitting, with an angle with respect to the temporary fitting guide groove. When the connect-side housing is attached to the base-side housing in the lever-type connector, the boss enters the boss opening portion, and the boss is guided to the tip position of the temporary fitting guide groove to form a state of temporary fitting. The housing seal is The boss is located at the tip of the temporary fitting guide groove. The present invention is characterized in that the contact surface is in contact with the mating contact surface in the above-mentioned state.

[0014] In addition, in the lever-type connector according to the present invention, The housing seal contains a silicone material. It is characterized by:

[0022] The lever-type connector of the present invention will now be described with reference to the drawings. However, the present invention is not limited to the following examples as long as the gist of the present invention is not exceeded.

[0023] A schematic diagram of a lever-type connector according to an embodiment of the present invention is shown in Fig. 1. The lever-type connector 10 shown in the figure includes a base-side housing 20 that houses a plurality of male terminals (also called base terminals), and a connect-side housing 40 that houses a plurality of female terminals (also called connect terminals) that can be connected to the male terminals and is provided with a cover portion 30a having a rotatable lever 30.

[0024] A terminal connection plate 22 is provided inside the base housing 20, approximately perpendicular to the mating direction, and a plurality of male terminals are housed above the terminal connection plate 22 (above when viewed from the front in FIG. 1). The plurality of male terminals are connected to the upper surface of the terminal connection plate 22.

[0025] The unit side connector (wiring from an in-vehicle device) is inserted into the base side housing 20 from an opening located at the bottom (lower end) of the base side housing 20 and connected to the bottom surface of the terminal connection plate 22. That is, the multiple male terminals and the unit side connector are electrically connected via the terminal connection plate 22. Also, a substantially circular boss 24 used for stepwise engagement with the connect side housing 40 is provided at an upper position approximately in the center of the base side housing 20 in the longitudinal direction (toward the connect side housing 40 in FIG. 1).

[0026] Here, as will be described in detail later, the lever-type connector 10 according to this embodiment is a step-by-step mating, that is, it goes through a provisional mating state and then goes into a real mating state (a state in which the male terminal and the female terminal are electrically connected). In this specification, the term "mating" includes both provisional mating and real mating.

[0027] The base-side housing 20 is provided with a substantially rectangular outer peripheral edge 26 that forms an opening (entrance) through which the female terminal is inserted in the direction in which the connect-side housing 40 is attached to the base-side housing 20. The outer peripheral edge 26 is provided with a taper 26a that is inclined toward the inner surface of the side wall of the base-side housing 20.

[0028] The taper 26a is provided for position adjustment (for alignment of the connectors (20 and 40)) for proper electrical connection between the male terminals and the female terminals when mating. In this embodiment, the taper 26a also plays a role in guiding a housing seal (described in detail later) provided inside the connect-side housing 40. In addition, the inner surface of the side wall of the base-side housing 20 has a mating contact surface 28 that comes into contact with the connect-side housing 40 when mating (the upper position on the inner surface of the side wall of the base-side housing 20 functions as the mating contact surface 28).

[0029] The connector-side housing 40 is provided with a terminal connection plate (not shown) similar to the base-side housing 20, and a plurality of female terminals are accommodated below the terminal connection plate. The plurality of female terminals are connected to the underside of the terminal connection plate.

[0030] The lever 30 has a generally gate-like shape and is disposed generally perpendicular to the longitudinal direction of the connect-side housing 40 so as to sandwich a cover portion 30a located above the connect-side housing 40 (above when viewed from the front in FIG. 1). The cover portion 30a serves as an inlet and a protective cover for the harness connector (vehicle harness).

[0031] 1, the harness connector is inserted from the opening on the right side of the cover portion 30a. The harness connector is connected to the upper surface of a terminal connection plate provided in the connector-side housing 40. In other words, the multiple female terminals and the harness connector are electrically connected via the terminal connection plate.

[0032] Next, the mating operation between the base side housing 20 and the connect side housing 40 will be described. Fig. 2 shows a schematic explanatory diagram of the mating operation in a lever type connector according to an embodiment of the present invention. In this specification, the mating operation refers to the operation of a worker mating a lever type connector on-site, that is, the operation of electrically connecting a male terminal and a female terminal. In Fig. 2, in order to provide an easy-to-understand overview of the mating operation, a description of the detailed structure of the lever type connector 10 (for example, the uneven structure and curved structure of each housing) is omitted.

[0033] First, the worker brings the connect-side housing 40 close to an upper position of the base-side housing 20 (an upper position when viewed from the front in FIG. 2(a)) as shown in FIG. 2(a). At this time, the base-side housing 20 and the connect-side housing 40 are in a non-contact state. Then, as shown in FIG. 2(b), the worker attaches the connect-side housing 40 to the base-side housing 20 to form a temporary fit.

[0034] Specifically, the lever 30 is provided with an operating portion 32 located at the upper end in Fig. 2(b) and a circular cam protrusion 34 at the end opposite to the operating portion 32 (the lower end of the lever 30 in Fig. 2(b)). The circular cam protrusion 34 in this embodiment is configured with four protrusions on a circular cam.

[0035] In this embodiment, the circular cam protrusion 34 has four protrusions, but the number of protrusions is not particularly limited. For example, the circular cam protrusion 34 may be configured with two protrusions, three protrusions, or five or more protrusions on a circular cam.

[0036] A generally rectangular boss guide plate 44 having a cam groove 42 with which the circular cam protrusion 34 meshes like a gear is provided at approximately the center in the longitudinal direction of the connect-side housing 40. The boss guide plate 44 also has a boss opening 44a through which the boss 24 can enter in the mating direction, and a temporary mating guide groove 44b extending linearly upward.

[0037] The temporary fitting guide groove 44b is further connected to the real fitting guide groove 44c which extends diagonally upward to the right (diagonally upward to the right when viewed from the front in FIG. 2). In this embodiment, the temporary fitting guide groove 44b is connected to the real fitting guide groove 44c which extends diagonally upward to the right, but in reality, the temporary fitting guide groove 44b may be connected to the real fitting guide groove 44c which extends diagonally upward to the right at an angle to the temporary fitting guide groove 44b and which extends diagonally in the direction in which the operating part 32 is located during real fitting.

[0038] The tip of the actual mating guide groove 44c is semicircular, and further below this tip (below the semicircular shape) is provided a boss fixing recess 44d so that the boss 24 is fixed (so that the boss 24 does not move) during actual mating. Also, at an upper internal position of the connect side housing 40, a substantially rectangular housing seal 50 is provided to ensure waterproofing of the lever-type connector 10 (male terminals and female terminals) during actual mating and to achieve good fixation between the housings.

[0039] When the connect-side housing 40 is attached to the base-side housing 20, the boss 24 of the base-side housing 20 enters the boss opening 44a of the connect-side housing 40, and the boss 24 is guided to the upper end position (tip position) of the temporary mating guide groove 44b. This is the temporary mating state of the lever-type connector 10 according to this embodiment.

[0040] In this case, for example, a temporary mating convex portion may be provided on one of the side walls of the base side housing 20 and the side wall of the connect side housing 40, and a temporary mating concave portion may be provided on the other, so that when the temporary mating state is reached, the temporary mating convex portion and the temporary mating concave portion are engaged with each other, thereby enabling the temporary mating state to be firmly maintained.

[0041] Then, when force is applied to the operating portion 32 in the temporary mating state as shown in FIG. 2(c) to rotate the lever 30, the circular cam protrusion 34 is guided along the cam groove 42, and the boss 24 located at the tip of the temporary mating guide groove 44b is guided diagonally upward to the right along the real mating guide groove 44c, so that the base side housing 20 and the connect side housing 40 are attracted to each other.

[0042] That is, the base housing 20 and the connect housing 40 are attracted to each other and are finally mated, and at the same time, the male terminals housed in the base housing 20 and the female terminals housed in the connect housing 40 are electrically connected. This is the final mating state of the lever-type connector 10.

[0043] In this manner, the lever-type connector 10 according to this embodiment first forms a temporary mating state, and then the base-side housing 20 and the connect-side housing 40 are permanently mated by rotating the lever 30, thereby electrically connecting the male terminals and the female terminals. The mating operation of the lever-type connector 10 according to this embodiment is generally carried out in the above-mentioned manner.

[0044] When attempting to rotate the lever 30 in the provisionally engaged state (the state shown in FIG. 2(b)), the housings (the base housing 20 and the connect-side housing 40) will tilt (shake) with the boss 24 as the fulcrum. side This may result in tilting relative to the housing 20, or further misalignment may occur due to this tilt.

[0045] This tilt or misalignment of the housings can cause the above-mentioned misfit, etc. Furthermore, if the lever 30 is rotated while the housings are tilted, the housings will be mated while still in the tilted state, causing a jam and requiring a larger insertion force (or force to rotate the lever 30) than usual.

[0046] In this embodiment, therefore, a lever-type connector 10 having a characteristic configuration is realized to prevent the housings from tilting relative to each other due to the rotational operation of the lever 30. The characteristic configuration of the present invention will be described in detail below.

[0047] FIG. 3 shows a schematic image of the lever-type connector according to this embodiment, with the connect-side housing 40 main body (side wall of the housing, etc.) omitted (cover portion 30a and the like provided on the connect-side housing 40 main body are shown as is). FIG. 4 shows a schematic diagram showing the positional relationship between the base-side housing 20 and the housing seal 50 in this embodiment. Here, the features of the present invention will be explained with reference to FIG. 3 and FIG. 4. A feature of the present invention is that the housing seal 50 provided on the connect-side housing 40 contacts the mating contact surface 28 of the base-side housing 20 (the inner surface of the side wall of the base-side housing 20) not only during actual mating but also in a temporary mating state.

[0048] As shown in Fig. 3(a), the housing seal 50 is located above (on the cover portion 30a side) the connector case 40a that is located inside the connect-side housing 40 and accommodates the female terminals. In Fig. 3(a), the housing seal 50 appears to be placed on the connector case 40a, but in reality the housing seal 50 is fixed to the main body of the connect-side housing 40 (the cover portion 30a appears to be floating, but in reality it is fixed at a position above the connect-side housing 40).

[0049] The housing seal 50 has greater flexibility than at least the base side housing 20 and the connect side housing 40. In the pre-mating state of Fig. 3(a), the base side housing 20 and the housing seal 50 are not in contact with each other (Fig. 4(a)).

[0050] As shown in Fig. 3(b), when the boss 24 is located at the tip of the temporary mating guide groove 44b, i.e., in the temporary mating state, the housing seal 50 contacts the mating contact surface 28 (the inner surface of the side wall of the base-side housing 20) (Fig. 4(b)). At this time, the housing seal 50 is guided to the mating contact surface 28 of the base-side housing 20 by the taper 26a (see Figs. 1 and 4(a)). Thereafter, as shown in Fig. 3(c), the lever 30 is rotated to form a permanent mating state, and in this permanent mating state, the housing seal 50 is guided to the inside of the base-side housing 20 (Fig. 4(c)).

[0051] 5, the housing seal 50 is provided with a plurality of lips 52 (52a, 52b, 52c) in a direction substantially perpendicular to the mating direction, and the lips 52 are provided to give the housing seal 50 a substantially insulator shape as a whole. - It is preferable that the insulating layer is made of a polyaniline material.

[0052] Furthermore, in this embodiment, it is preferable that at least one of the lips 52 of the housing seal 50 is deformed by pressure in a temporary fitting state. In this specification, the term "deformation by pressure" does not limit the direction of pressure, and means that the relevant portion (lip 52) is in some kind of deformed state regardless of the force from any direction.

[0053] By deforming the lip 52 under pressure, it is possible to more reliably prevent the housings from being misaligned or tilted relative to each other. By deforming the lip 52 under pressure during temporary engagement, it is also possible to cope with a force greater than normal being applied due to a sudden rotational operation of the lever 30. This deformation under pressure can be achieved by applying a force of, for example, about 10N to 20N.

[0054] In this embodiment, a lock end 40b can be provided at an upper position of the connector case 40a (see FIG. 3(a)) in order to smoothly guide the housing seal 50 into the base-side housing 20. For example, in a structure in which the lock end 40b is not provided as shown in FIG. 6(a), there is a risk that the tip end (outer peripheral edge 26) of the side wall of the base-side housing 20 and the housing seal 50 will interfere with each other during mating (twisted mating state).

[0055] In this embodiment, a lock end 40b is provided at the upper position of the connector case 40a as shown in FIG. 6(b), forming a visor, which can suppress interference and twisting (twisted engagement) caused by the tip of the base side housing 20.

[0056] For example, the connector housing 40 according to the present embodiment includes a housing seal 50 located in the mating direction and facing the mating contact surface 28 during temporary mating. direction A lock end 40b for suppressing interference between the outer peripheral edge 26 and the housing seal 50 can be provided at the position corresponding to the lock end 40b.

[0057] Here, the positional relationship between the base-side housing 20 and the connect-side housing 40 during temporary mating will be described. In the lever-type connector 10 according to this embodiment, the positional relationship between the base-side housing 20 and the connect-side housing 40 is determined mainly by the position of the boss 24 relative to the boss guide plate 44.

[0058] 7 is a schematic image diagram showing the positional relationship between the boss guide plate and the boss in the lever-type connector of this embodiment. For example, in the general boss guide plate 144 shown in FIG. 7(a), even if the boss 124 is located at the upper end (tip) of the temporary mating guide groove 144b, the housing seal and the mating contact surface are not actually in contact with each other.

[0059] In contrast, in the boss guide plate 44 of this embodiment, as shown in Figure 7 (b), the length of the guide groove in the temporary mating guide groove 44b is made longer than the length of the guide groove in a typical boss guide plate 144 (because the tip position is set at a higher position). In other words, by devising the shape of the boss guide plate 44 (temporary mating guide groove 44b), the distance from the temporary mating state to the actual mating state is shortened.

[0060] Therefore, in this embodiment, the distance in the mating direction between the base side housing 20 and the connect side housing 40 during temporary mating can be made closer than in the conventional case, so that the housing seal 50 and the mating contact surface 28 are in contact with each other in the temporary mating state.

[0061] For example, by providing the boss guide plate 44 of this embodiment to an existing lever-type connector (for example, by simply changing the boss guide plate without changing other configurations such as the lever and boss), the effects of the present invention can be obtained.

[0062] With this configuration, it is possible to prevent the housings (the base side housing 20 and the connection side housing 40) from tilting about the boss 24 during mating, thereby preventing improper mating. Also, the effects of the present invention can be obtained even when a part of the housing seal 50 is in pressure contact with a part of the mating contact surface 28 during temporary mating, for example.

[0063] Furthermore, in the lever-type connector 10 of this embodiment, the sliding distance of the boss 24 during actual mating is shorter than that of a typical lever-type connector (in a typical configuration, the housing seal and the mating contact surface are not yet in contact in the temporary mating state, so the sliding distance is longer by that distance), and further, the angle of the actual mating guide groove 44c is gentle, resulting in a reduction in the force required to rotate the lever.

[0064] In this way, the lever-type connector 10 of the present invention is configured so that the housing seal 50 and the mating contact surface 28 (inner surface of the side wall) come into contact during temporary mating, which makes it possible to prevent tilting (wobbling) of the housings during actual mating with a simple configuration and reduces the force required to rotate the lever 30. As a result, the lever-type connector 10 of the present invention can prevent erroneous mating (a state in which the housings are not fully mated, or a state in which the terminals are not fully connected or not connected at all, etc.) and is also expected to improve workability in the field.

[0065] The lever-type connector 10 according to this embodiment can also be provided with a CPA function (connector position assurance function) during proper mating. Here, the CPA function in this specification refers to a locking mechanism that prevents the lever-type connector from being unintentionally detached when properly mated.

[0066] By changing the cover portion 30a in this embodiment to a cover portion 30b with a CPA function as shown in FIG. 8, for example, the CPA function of the lever-type connector 10 can be realized. orientation In order to provide an easy-to-understand outline of the CPA function, a detailed description of the structure (such as the uneven structure and curved structure) of the CPA function-equipped cover portion 30b will be omitted in Fig. 8 .

[0067] The CPA function-equipped cover part 30b is provided with a CPA protrusion 30c. The CPA protrusion 30c is provided so as to be movable within a predetermined range on the upper surface of the CPA function-equipped cover part 30b, that is, to a position where the CPA protrusion 30c and the CPA recess 30d provided in the operation part 32 are mated during actual mating.

[0068] After the worker confirms that the lever-type connector 10 is in a fully engaged state, he or she horizontally moves the CPA protrusion 30c to engage the CPA protrusion 30c with the CPA recess 30d (FIG. 9). By providing the lever-type connector 10 with the CPA function in this way, a more reliable and permanent electrical connection can be achieved.

[0069] In addition, in the present embodiment, a lever-type connector for connecting an in-vehicle harness and an in-vehicle device has been described, but the same effects can be obtained with lever-type connectors in other fields. can be done Furthermore, in this embodiment, the base housing accommodates male terminals and the connect housing accommodates female terminals, but the same effect can be obtained even if, for example, the base housing accommodates female terminals and the connect housing accommodates male terminals. can be done Of course, the lever-type connector 10 according to the present invention can provide the same effect when used with terminals other than male and female terminals. can be done .
