Description

[Technical Field]

[0001] The present invention relates to a connector, particularly to a lever-type connector, and to a technique for suppressing tilting of housings relative to each other caused by a mating operation. [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] A typical lever-type connector has multiple male terminals housed in one housing and multiple female terminals housed in the other housing. By rotating a lever provided on either housing, the two housings are pulled toward each other and mated together. As a result, the male and female terminals are electrically connected properly.

[0004] As mentioned above, the mating of the two housings (connecting the male and female terminals) is generally performed by a worker on-site, such as in a factory. In other words, the on-site environment is not necessarily suitable for mating lever-type connectors. For example, there may be situations where it is difficult to visually check 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 mated state, and then rotate the lever to fully mated 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), the mating operation can be carried out properly. However, if the relative positions of the housings deviate from the correct posture during temporary mating, or if the housings tilt due to the mating operation, there is a risk of the housings being mated incorrectly (the housings are not fully mated, or the terminals are not connected properly or are not connected at all, etc.).

[0007] In addition, if the housings tilt due to the mating operation, the mating resistance between the housings may increase. For example, if the strength of the boss (specifically, a cylindrical protrusion, etc.) used during mating is weaker than the mating resistance, the boss may be damaged.

[0008] Patent Document 1 discloses a technology relating to a connector engagement device that allows the male connector to be mated and connected smoothly along the center line of the connection direction by providing engagement pins on the second connector that can be engaged with the actuating cam grooves of the first and second actuating cam members of the first connector, which are arranged to be interlocked with each other. As a result, the reliability of the interconnection between the female connector terminal groups and the male connector terminal groups can be improved. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Japanese Patent Application Publication No. 8-37057 Summary of the Invention [Problem to be solved by the invention]

[0010] As described above, by utilizing the technology of Patent Document 1, that is, by always directing the force generated by the mating operation toward the center line of the connection direction (by concentrating the force generated during the mating operation at approximately the center of the longitudinal direction of both connectors), tilting of the housings caused by the mating operation can be suppressed compared to conventional connectors.

[0011] However, the technology of Patent Document 1 makes the structure of the mating device much more complicated than conventional products (a total of four operating cam members). As a result, the technology of Patent Document 1 requires four or more bosses, and is not compatible with typical lever-type connectors that have two bosses.

[0012] Furthermore, for example, due to manufacturing errors, etc., there may be slight differences in the shape of each product, and if the concentration of force during the mating operation is even slightly shifted from the longitudinal center of the first connector or the second connector, there is a risk that the inclination between the connectors (housings) will be greater than before.

[0013] The present invention was made in consideration of the problems with the above-mentioned conventional technology, and its purpose is to provide a lever-type connector that has a simple configuration, suppresses tilting of the housings caused by the mating operation, and even in the case of two bosses, suppresses an increase in mating resistance between the housings, thereby preventing damage to the bosses.

[0022] The lever-type connector of the present invention will be described below with reference to the drawings, but the present invention is not limited to the following examples as long as it does not depart from the spirit of the present invention.

[0023] Figure 1 shows a schematic diagram of a lever-type connector according to an embodiment of the present invention. 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-side terminals), and a connect-side housing 40 that houses a plurality of female terminals (also called connect-side 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-side housing 20, approximately perpendicular to the fitting direction, and a plurality of male terminals are housed above the terminal connection plate 22 (above when viewed from the front in FIG. 1). These 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 through an opening located at the bottom (lower end) of the base-side housing 20 and connected to the underside of the terminal connection plate 22. In other words, the multiple male terminals and the unit-side connector are electrically connected via the terminal connection plate 22. Furthermore, a substantially cylindrical boss 24 used for fitting (or stepwise fitting) 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] As will be described in detail later, the lever-type connector 10 according to this embodiment is mated in stages, that is, it goes through a provisional mating state and then reaches a fully mated state (a state in which the male terminals and female terminals are electrically connected). Furthermore, when the term "mating" is used in this specification, it can mean both provisional mating and fully mated, or it can mean that the base-side housing 20 and the connect-side housing 40 are mated directly without going through a staged mechanism.

[0027] The base 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 housing 20 .

[0028] 1, the outer peripheral edge 26 may be provided with a taper 26a that is inclined toward the inner surface of the side wall of the base housing 20. This taper 26a serves to adjust the position (for alignment between the housings (20 and 40)) for proper electrical connection between the male terminal and the female terminal when mated.

[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 housed 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 roughly gate-like shape and is arranged roughly perpendicular to the longitudinal direction of the connect-side housing 40, sandwiching the cover portion 30a located above the connect-side housing 40 (above when viewed from the front in Figure 1).

[0031] 1, and a circular cam protrusion 34 at the end opposite to the operating portion 32 (the lower end of the lever 30 in FIG. 1). Furthermore, in this embodiment, a reverse rotation gear 36 having a characteristic function of the present invention is provided so as to form a gear mechanism together with the circular cam protrusion 34.

[0032] In this embodiment, the circular cam protrusion 34 is configured with four protrusions on a circular cam. Note that the number of protrusions is not particularly limited in this embodiment, and for example, the circular cam protrusion 34 may be configured with two protrusions, three protrusions, or five or more protrusions on a circular cam. Similarly, the number of protrusions (number of gears) in the reverse rotation gear 36 is not particularly limited.

[0033] The cover portion 30a serves as an inlet and protective cover for the harness connector (vehicle harness). Specifically, when viewed from the front in FIG. 1, the harness connector is inserted through 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.

[0034] Next, a description will be given of the mating operation between the base-side housing 20 and the connector-side housing 40. Figure 2 shows a schematic explanatory view of the mating operation in the lever-type connector according to the embodiment of the present invention.

[0035] In this specification, the term "mating operation" refers to the operation of a worker mating lever-type connectors on-site, i.e., the operation of electrically connecting male and female terminals (the operation of electrically connecting terminals housed in both housings). In order to provide an easy-to-understand overview of the mating operation, detailed structural details of lever-type connector 10 (such as the uneven and curved structures of each housing) are omitted from Figure 2.

[0036] 2 provides a detailed explanation of how the components (e.g., slider plates, etc.) arranged on both longitudinal sides of the lever-type connector 10 operate during the mating process. For this reason, Fig. 2 shows the connector housing 40 with the side walls and other components removed so that the components on both sides can be seen.

[0037] 2 is referred to as the first side surface 12, and the side surface located on the front side in FIG. 2 is referred to as the second side surface 14. In this specification, of the two side surfaces, the first side surface 12 may be referred to as one side, and the second side surface 14 may be referred to as the other side.

[0038] First, we will explain the specific configurations of the first side surface 12 and the second side surface 14. On the first side surface 12, approximately at the center in the longitudinal direction of the connect-side housing 40, there is provided a slider plate 44 (also referred to as the first slider plate) having a substantially rectangular plate shape and having a cam groove 42 (also referred to as the first cam groove) with which the circular cam protrusion 34 meshes like a gear.

[0039] During mating, the first slider plate 44 slides in the longitudinal direction of the connector housing 40. The first slider plate 44 has a boss opening 44a through which the boss 24 can enter in the mating direction, and also has a temporary mating guide groove 44b that extends linearly upward.

[0040] The temporary fitting guide groove 44b is connected to a regular fitting inclined groove 44c that extends linearly at an angle relative to the temporary fitting guide groove 44b. The tip of the regular fitting inclined groove 44c is semicircular, and 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 regular fitting.

[0041] The connect side housing 40 on the second side surface 14 is provided with a slider plate 54 (also called the second slider plate) that slides in the longitudinal direction of the connect side housing 40, as well as a reverse rotation gear 36 that is located between the circular cam protrusion 34 and the cam groove 52 in a gear mechanism that includes at least a cam groove 52 (also called the second cam groove) and slides the second slider plate 54 in the opposite direction relative to the first slider plate 44 (slider plate 44 on the first side surface 12).

[0042] The second slider plate 54 has a boss opening 54a through which the boss 24 can enter in the mating direction, and a temporary mating guide groove 54b extending linearly upward and connected to a regular mating inclined groove 54c. Naturally, the regular mating inclined groove 54c on the second side surface 14 is also provided with a boss fixing recess 54d.

[0043] 2, the position of the convex portion of the circular cam convex portion 34 differs between the first side surface 12 and the second side surface 14. That is, on the first side surface 12, a convex portion is provided at a position where the circular cam convex portion 34 engages with the first cam groove 42 of the first slider plate 44, and on the second side surface 14, a convex portion is provided at a position where the circular cam convex portion 34 engages with the reverse rotation gear 36.

[0044] First, as shown in FIG. 2(a), the worker brings the connect-side housing 40 close to and into contact with the upper position of the base-side housing 20 (the upper position when viewed from the front in FIG. 2(a)). At this time, the base-side housing 20 and the connect-side housing 40 are in a state before temporary mating. Then, as shown in FIG. 2(b), the worker attaches the connect-side housing 40 to the base-side housing 20 (pushing the connect-side housing 40 further in from the state in FIG. 2(a)), thereby achieving a temporary mating state.

[0045] When the connect-side housing 40 is attached to the base-side housing 20, the bosses 24 of the base-side housing 20 enter the boss openings 44a, 54a of the connect-side housing 40 on both sides (first side 12, second side 14) as shown in Figure 2(b), and the bosses 24 are guided to the upper end positions (tip positions) of the temporary mating guide grooves 44b, 54b. This is the temporary mating state of the lever-type connector 10 according to this embodiment.

[0046] Then, when force is applied to the operating portion 32 in the provisionally fitted state to rotate the lever 30 as shown in Figure 2(c), the bosses 24 located at the tips of the provisional fitting guide grooves 44b, 54b on both the first side surface 12 and the second side surface 14 are guided along the full fitting inclined grooves 44c, 54c, and the base side housing 20 and the connect side housing 40 are drawn together.

[0047] At this time, on the first side surface 12, the circular cam protrusion 34 and the cam groove 42 engage with each other as the lever 30 is rotated, and the first slider plate 44 is guided in the longitudinal direction of the connect side housing 40 in the opposite direction to the position of the operating part 32 after the rotation operation, i.e., the first slider plate 44 slides in the opposite direction to the position of the operating part 32.

[0048] Furthermore, on the second side surface 14, when the lever 30 is rotated, the circular cam protrusion 34 and the reverse rotation gear 36 mesh together, and at the same time, the reverse rotation gear 36 meshes with the cam groove 52, thereby guiding the second slider plate 54 in the longitudinal direction of the connect side housing 40 in the same direction as the position of the operating part 32 after the rotation operation; that is, the second slider plate 54 slides in the same direction as the position of the operating part 32.

[0049] Thus, in this embodiment, during full fitting, the first slider plate 44 on the first side surface 12 and the second slider plate 54 on the second side surface 14 slide in opposite directions in the longitudinal direction of the connector housing 40.

[0050] In other words, the connect side housing 40 in this embodiment is provided with a rotation transmission part 34 (circular cam protrusion 34) that is provided on the lever 30 and transmits the rotation operation of the lever 30 as rotational motion, and slider plates 44, 54 that are provided with linear conversion parts 42, 52 (cam grooves 42, 52) that engage with the rotation transmission part 34 and can convert the rotational motion into linear motion.

[0051] The slider plates 44, 54 are provided with fitting inclined grooves 44c, 54c (main fitting inclined grooves 44c, 54c) that are inclined relative to the mounting surface of the base-side housing 20 and guide the boss 24 during fitting.

[0052] The slider plate of this embodiment is composed of a first slider plate 44 provided on the first side surface 12 of the connect side housing 40 parallel to the rotation plane of the lever 30, and a second slider plate 54 provided on the second side surface 14.

[0053] In addition, on either the first side surface 12 or the second side surface 14, a reverse rotation transmission section 36 is provided, which is located between the rotation transmission section 34 and the linear conversion section 52 and engages with the rotation transmission section 34 to convert the rotational motion into reverse rotational motion and transmit it, and the linear conversion section 52 engages with the reverse rotation transmission section 36 to convert the reverse rotational motion into linear motion.

[0054] With this configuration, when the lever-type connector 10 is mated, the boss 24 is guided into the mating inclined grooves (44c, 54c), and the first slider plate 44 and the second slider plate 54 slide in opposite directions.

[0055] Here, the operation of the slider plates will be described. Figure 3 is a schematic diagram showing the direction in which each slider plate moves when mated in this embodiment. In Figure 3, the first side surface 12 is shown reversed from the front in order to clearly explain the sliding movement of each slider plate when mated (to explain the operational relationship between the first slider plate 44 and the second slider plate 54).

[0056] As shown in the figure, by rotating the lever 30, the first slider plate 44 on the first side surface 12 slides in the direction of the lever position before the rotation operation (toward the operating part 32 before the rotation operation), and on the second side surface 14, the second slider plate 54 slides in the opposite direction to the first slider plate 44 on the first side surface 12.

[0057] In other words, with conventional lever-type connectors, there is a risk that the two housings may tilt relative to each other due to the mating operation, but in this embodiment, by sliding each slider plate in opposite directions, it is possible to suppress the tilt caused by the mating operation.

[0058] 2(c), as the slider plates 44, 54 slide, the base-side housing 20 and the connect-side housing 40 are pulled together (the bosses 24 are guided into the full-fitting inclined grooves 44c, 54c), and at the same time, the male terminals housed in the base-side housing 20 and the female terminals housed in the connect-side housing 40 are electrically connected. This is the full-fit state of the lever-type connector 10.

[0059] In this way, in the lever-type connector 10 of this embodiment, a provisional mating state is first formed, and then the lever 30 is rotated to slide both slider plates 44, 54 in opposite directions to fully mating the base side housing 20 and the connect side housing 40.

[0060] As a result, the male terminals and female terminals can be electrically connected safely and reliably while preventing tilting or mis-mating of the housings. The mating operation of the lever-type connector 10 according to this embodiment is generally carried out as described above.

[0061] Preventing tilt between housings Next, we will explain the tilt between the housings caused by the mating operation in a lever-type connector. Figure 4 shows a schematic image of the tilt caused by the mating operation. As shown in the figure, when the lever 30 is rotated, the slider plate (specifically, the lower position where the boss 24 contacts the mating inclined groove) receives a reaction force from the boss 24 during mating. Note that in this specification, the reaction force refers to the force generated at the support point against an external force acting on an object, or a force equivalent to this.

[0062] In a lever-type connector, if the direction in which this reaction force occurs (the direction of the force) is perpendicular to both housings (20 and 40), such tilting would not occur, but in a lever-type connector like this embodiment, in which the housings are mated by rotating the lever, the direction of the reaction force inevitably forms an angle with the vertical due to its configuration, as shown in Figure 4. As a result, the housings tilt due to the rotation of the lever, i.e., due to the mating operation.

[0063] 3, a reverse rotation gear 36 is provided on the second side surface 14, and two slider plates 44, 54 on both sides (first side surface 12, second side surface 14) slide in opposite directions, thereby canceling out the reaction force received from the boss 24. As a result, the lever-type connector 10 according to this embodiment can prevent the housings from tilting relative to each other due to the mating operation.

[0064] In addition, in conventional lever-type connectors, the two slider plates on both sides slide in the same direction when mated (because they are arranged symmetrically when mated), so it was necessary to prepare two types of sliders for each.

[0065] On the other hand, by sliding the slider plates 44, 54 in opposite directions as in this embodiment, the slider plates 44, 54 are arranged point-symmetrically when mated, so that the first slider plate 44 provided on the first side surface 12 and the second slider plate 54 provided on the second side surface 14 can be made to have approximately the same shape.

[0066] Variations Figure 5 shows a schematic image of a modified lever-type connector according to this embodiment. In Figure 5, components common to the lever-type connector 10 shown in Figures 1 to 4 are indicated by adding 100 to the reference numerals. Note that Figure 5(a) shows a schematic image of lever-type connector 110 according to the actual modified example, and Figure 5(b) shows the slider plate, which is characteristic of this modified example, so that it can be seen.

[0067] As shown in Figure 5(b), lever-type connector 110 according to this modified example has a structure in which reverse rotation gear 136 is directly mounted on slider plate 154. Furthermore, cam groove 152 is provided at a position where reverse rotation gear 136 and reverse rotation gear 136 form a gear mechanism, i.e., below reverse rotation gear 136.

[0068] By configuring the slider plate 154 in this way, the reverse rotation gear 36 is not positioned externally as in the embodiment shown in FIG. 2, and as a result, the lever-type connector 110 can be made lighter and more compact.

[0069] As described above, the lever-type connector 10 of the present invention has a reverse rotation transmission part on either the first side surface 12 or the second side surface 14 of the connect side housing 40, and when mating, the boss 24 is guided into the mating inclined groove 52c and the first slider plate 44 and the second slider plate 54 are caused to slide in opposite directions, thereby realizing a lever-type connector with a simple configuration that can suppress tilting of the housings (mis-mating) caused by the mating operation.

[0070] Furthermore, for example, by providing the reverse rotation gear 136 directly on the second slider plate 154, it is possible to suppress tilting of the housings caused by the mating operation, and also to make the lever-type connector 110 lighter and more compact.

[0071] Furthermore, in this embodiment (and the modified example), a stepwise mating process has been described in which a provisional mating state is followed by a proper mating process. However, the same effect as the present invention can also be obtained with a lever-type connector that has a configuration in which the housings are mated directly with each other without undergoing a stepwise mating process.

[0072] In addition, although the present embodiment has been described with reference to a lever-type connector for connecting an in-vehicle harness to an in-vehicle device, similar effects can be obtained with lever-type connectors in other fields. Can do.

[0073] 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 Naturally, the lever-type connector 10 according to the present invention can also provide similar effects with terminals other than male and female terminals. Can do. [Explanation of symbols]
