Abstract

An electric terminal comprises a U-shaped plate 2, a front plate 1 closing off the U, and a terminal screw 6. The U-shaped plate has an integral terminal portion 7, which may be a switch contact, and projecting portions 5 to hold the front plate. The screw goes through the front plate, and can hold a wire between the tip of the screw and the U-shaped plate. The front plate may be integral with a stopper portion 3 which the wire abuts. As this is separate from the terminal portion 7 the latter is more reliably positioned.

Description

2364186 WIRE-CONNECTIING TERMINAL CONNECTOR AND SWITCHING DEVICE FOR
WIRING ACCESSORY TECHNICALFEEM The present invention relates to a connector and a switching device that includes a terminal for connecting a wire and that is used for a wiring accessory, such as a switch or a receptacle.
BACKGROUNDART
Conventionally as shown in Fig 15, a wire-connecting terminal connector (which is a so-called "pillar terminal", and which hereinbelow will be simply referred to as a "connector") is configured of a terminal section 16 and a terminal screw 6, wherein the terminal section 16 is constituted of a wire-holding terminal plate 14 and a terminal plate 15 As shown in Fig 16, a plate is bent in such a manner as to substantially form a letter "U" in a plain cross sectional view, thereby forming a wire-holding terminal plate 14 on an inner face of a central portion thereof The wire-holding section 14 holds a core 8 a of a wire 8 in a space formed with an end portion of the terminal screw 6 engagingly inserted into a threaded hole 17 of a bent-down portion of the terminal plate 15 In addition, insertion holes 14 b are formed to receive projections 18 provided on a sidewall of the terminal plate 15.
As shown in Fig 17, the terminal plate 15 is formed in a manner wherein the threaded hole 17 is provided in a central portion thereof, and the aforementioned plurality of projections 18 are formed on two side ends in the longitudinal direction to protrude in the width direction In addition, a stopper portion 19 is formed integrally with the terminal plate 15, upon which the end of the core 8 a of the wire 8 abuts when the wire 8 is inserted toward an upper end portion of the terminal plate 15 A terminal portion is integrally formed in an end portion of the stopper portion 19, and a fixed contact 20 to be used for a switch is formed on an outer surface of the stopper portion 19.
The terminal section 16 is formed by coupling the wire-holding terminal plate 14 and the terminal plate 15 together according to a procedure illustrated in Fig 18 Specifically, as shown in 18 (a), prior to the coupling, two end portions of the wire-holding terminal plate 14 are widely spaced from each other In this state, the projection 18 of the terminal plate 15 shown in Fig 18 (b) is inserted into the one-side insertion hole 14 b, and the opposite end portion is closed Then, as shown in Fig 18 (c), the projection 18 is inserted into the insertion hole 14 b of the end portion, and caulking is performed for the projections 18 of two sides.
Thereby, the wire-holding terminal plate 14 and the terminal plate 15 are fixedly coupled According to the aforementioned coupling, the terminal section 19 is completed, as shown in Fig 16 In this state, the terminal screw 6 is engagingly inserted into the threaded hole 17; and thereby, coupling can be achieved.
However, the above conventional example of the connector arises a problem in that since the terminal plate 15 is inserted into the wire- holding terminal plate 14, and caulking is performed Therefore, work steps and assembly costs are thereby increased Another problem is that, while the normal condition is as shown in Fig 15, when the wire 8 is inserted by exerting a force, as shown in Fig 20, the stopper portion 19 is pressed to the extent of causing deformation by the end of a core 8 a of the wire 8; and as a result, deviation is caused in the position of the contact 20.
DISCLOSURE OF NVENON
The present invention is made in view of the above-described problems.
Accordingly, an object of the present invention is to provide a wireconnecting terminal connector that does not cause the deviation in a terminal portion during wire insertion, and in addition, that allows reduction in assembly steps and production costs to be implemented.
In order to achieve the above object, the present invention is characterized that, a connector to be used with a wiring accessory and having a wire- connecting terminal, by comprising a terminal screw; a first terminal plate formed to include a central portion formed to have a substantially U-shaped plan cross section, bilateral portions thereof, and a terminal portion integrally formed to continue outwardly from the central portion, wherein an opening is formed between ends of the bilateral portions; and a second terminal plate formed to include a stopper portion and a bent-down portion, wherein the stopper portion is formed to extend between upper end portions of the bilateral portions of the first terminal plate and upon which the end of a wire is brought to about, and the bent-down portion is integrally formed to be pendent along the opening of the first terminal plate from one end of the stopper portion and to have a threaded hole into which the terminal screw is engagingly inserted In addition, a wire insertion entry for inserting the wire is formed by being surrounded by lower ends of the bilateral portions of the first terminal plate and the lower end of the bent-down portion of the second terminal plate The wire inserted from the wire insertion entry is held between an inner surface of the central portion and the end of the terminal screw engagingly inserted from the threaded hole.
According to the above-described present invention, the first terminal plate and the second terminal plate can be coupled without performing caulking.
This simplifies the assembly, thereby allowing reduction in assembly time and costs to be implemented Furthermore, since the stopper portion and the terminal portion are provided in the separate members, even when the stopper portion is deformed during the insertion of the wire, no deviations occur in positions of the terminal portion Thus, the contact position and the power connection position do not deviate even if the contact terminal portion and the power terminal portion are constituted by this terminal portion.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinbelow, embodiments will be described with reference to the drawings to set out the best mode of the present invention.
(FIRST EMBODIMENT) As shown in Fig 1, a connector (pillar terminal) of a first present embodiment is configured of a common terminal plate 1 in common among a power terminal and a contact terminal plate; a terminal plate 2 for a contact terminal, which is formed according to the present embodiment; and a terminal screw 6.
The common terminal plate 1 is formed by bending a plate with a right angle.
The one-side portion of the common terminal plate 1 is used to form a stopper portion 3 that abuts the end of a core 8 a of a wire 8 (shown in Fig 4), and the other portion is used to form a bent-down portion 4 having a threaded hole 10 formed in a central portion according to a counter sinking method The stopper portion 3 is formed to have projection portions 3 a at end portions, and the projection portions 3 a projects in the width direction thereof The bent-down portion 4 is formed to have engagement portions 4 a projecting in the lateral directions.
The terminal plate 2 is formed by bending a plate so that a plan section thereof has substantially the shape of a letter "U" Projected portions 5 are formed to forwardly project on the lower portions of the bilateral portion 2 b In upper end portions of the projected portions 5, there are formed insertion cutouts a that allow the insertion of lower ends of the engagement portions 4 a provided on the bent-down portion of the common terminal plate 1 In addition, indented portions 2 c upwardly opening are individually formed on upper end portions of bilateral portions 2 b and 2 b; a terminal portion 7 having the shape of a reversed letter "L" is integrally formed from an upper end portion of a central portion 2 a; and a fixed contact 7 a for a switch is provided on an outer surface of an end vertical portion.
The terminal plate 1 and the terminal plate 2, which constitute the connector of the present embodiment, are connected as follows As shown in Figs.
2 (a) and 2 (b) or Figs 3 (a) and 3 (b), lower ends of the engagement portions 4 a formed in the bent-down portion 4 of the terminal plate 1 are inserted into the insertion cutouts 5 a formed on upper end portions of the projected portions 5 formed to project in the lower portions of the bilateral portions 2 b of the terminal plate 2 The stopper portion 3 of the terminal plate 1 is mounted so as to extend between the bilateral portions 2 b and 2 b of the terminal plate 2 in the following manner The projection portions 3 a formed on the two side ends of the stopper portion 3 of the terminal plate 1 are engaged with in the indented portions 2 c, the bent-down portion 4 is lowered along front end faces of the bilateral portions 2 b and 2 b of the terminal plate 2, and the lower ends of the projected portions 5 are fitted into the insertion cutouts 5 a Concaved portions 2 d individually formed between upper portions and lower portions of the bilateral portions 2 b and 2 b work as escape portions for counter sinking.
In this way, a terminal section 12 is completed according to the common terminal plate 1 and the terminal plate 2, and a wire insertion entry 12 a is opened in a lower end portion thereof Then, the terminal screw 6 is engagingly inserted into the threaded hole 10 of the common terminal plate 1 Thereby, and the connector is completed.
As described above, the terminal section 12 can be assembled only by conducting the following two steps at the same time: one of the steps is the insertion of the engagement portions 4 a, which are formed in bent-down portion 4 of the common terminal plate 1, into the insertion cutouts 5 a of the projected portions 5 formed on the terminal plate 2, and the other steps is the insertion of the projection portions 3 a, which are formed in the stopper portion 3 of the common terminal plate 1, into the indented portions 2 c provided in the upper end portions of the bilateral portions 2 b of the terminal plate 2 Thus, the assembly does not require caulking to be performed, therefore providing an advantage in the reduction of the assembly costs.
As shown in Fig 4, the core 8 a of the wire 8 is inserted from the wire insertion entry 12 a provided in the terminal section 12, the core 8 a is then inserted between the end of the terminal screw 6 and an inner surface of the central portion 2 a of the terminal plate 2, and subsequently, the terminal screw 6 is tightened In this way, the core 8 a is held between the inner surface of the central portion 2 a and the end of the terminal screw 6; that is, the core 8 a of the wire 8 is mechanically held, and concurrently, is electrically connected In this case, even when the stopper portion 3 of the common terminal plate 1 is pushed up by the end of the core 8 a of the wire 8 and is thereby deformed as shown by dotted lines in the figure, the terminal portion 7 of the terminal plate 2 is not deformed.
Therefore, the position of the fixed contact 7 a is not changed.
As shown in Fig 5, chamfering 12 b is performed for an inner surface of an opening of the wire insertion entry 12 a provided to open at one end of the terminal section 12 Therefore, even when the wire 8 is rotated and moved, the core 8 a is not easily damaged.
In addition, the threaded hole 10 is formed with a countersink to extend in the internal direction of the terminal section 12, that is, toward the reverse surface of the bent-down portion 4 of the common terminal plate 1 Therefore, the screw stroke can be lengthened without changing the protrusion of the terminal screw 6.
Furthermore, abutting between the indented portions 2 c and the stopper portion 3 that abuts the indented portions 2 c, and insertion between the engagement portions 4 a and the insertion cutouts 5 a in which the engagement portions 4 a are inserted individually function to preserve stresses developed according to screw tightening torques in the case of tightening the terminal screw 6 This arrangement is advantageous in that the wire 8 can be held only by the terminal section 12.
To equip the connector of the present embodiment with a wiring accessory, for example, as shown in Figs 6 and 7, the grooved portions 13 a and 13 a opposing each other for slide-inserting projection ends 4 e of the engagement portions 4 a, which are formed in the bent-down portion 4 of the common terminal plate 1, are formed on two-side inner surfaces of a stowing concave portion 13 of a wiring- accessory body 11 In this configuration, the projection ends 4 e function as stress stoppers for stresses generated according to tightening torques in the case of tightening the terminal screw 6 Therefore, deformation of the terminal plates 1 and 2 at the terminal section 12 can be further reduced by the wiring- accessory body 11.
(SECOND EMBODIMENT) Fig 8 shows a second embodiment In the second embodiment, a connector in which the position of the fixed contact 7 a is different from the above by can be configured by combining the common terminal plate 1 and a terminal plate 2 as follows The terminal plate 2 is formed such that a terminal portion 7 is formed of a planar portion outwardly extending from an upper end portion thereof and a vertical portion integrally extending from the end of the planar portion in the lateral directions, and a fixed contact 7 a is provided on an outer surface of an end portion of the vertical portion.
(THIRD EMBODIMENT) Fig 9 shows a third embodiment Similarly to the above, in the third embodiment, a connector in which the position of the fixed contact 7 c is different from those of the above-described connectors can be configured by combining the common terminal plate 1 and a terminal plate 2 as follows The terminal plate 2 is formed such that a terminal portion 7 is formed of a long and planar portion outwardly extending from an upper end portion thereof and a vertical portion integrally extending from the end of the planar portion in the lateral directions, and a fixed contact 7 c is provided on an inner surface of an end portion of the vertical portion.
(FOURTH EMBODIMENT) Fig 10 shows a fourth embodiment Each of the above-described connectors is formed by combining the terminal plate 2 having the fixed contact with the common terminal plate 1 According to the fourth embodiment, a terminal plate 2 described below is combined with the common terminal plate 1 to thereby enable a connector having a power terminal to be configured As shown in Fig 10, the terminal plate 2 is formed such that a contact portion 7 a' having a mountain-like shape upwardly protruding is formed at the edge of a terminal portion 7 that integrally extends outwardly from a lower end portion of a central portion 2 a The terminal plate 2 serves as a power terminal plate.
(FIFTH EMBODIMENT) For the common terminal plate 1, as shown in Fig 11, a common terminal plate having a diagonally formed one-end side of projection portions 3 a may be used Basically, however, various types of connectors can be realized according to the combination of the common terminal plate 1 with the terminal plate 2.
In addition, as shown in Fig 12, the threaded hole 10 to be provided around the center of the bent-down portion 4 of the common terminal plate 1 may be formed of a hole section that is formed with a countersink 9 so as to project in the obverse direction of a bent-down portion 4 The provision of the countersink produces an advantage in that the amount of screw engagement between the terminal screw 6 and the threaded hole 10 is increased That is, the stroke of the terminal screw can be lengthened without changing the protrusion of the terminal screw.
As described above, according to the present invention, a first terminal plate and a second terminal plate can be coupled together through the insertion, and different from the conventional case, the assembly does not require caulking to be performed Thereby, the assembly is facilitated, and the assembly time and costs can be reduced.
The individual constructions of the first terminal plate 2 and the second terminal plate 1 and the coupling configuration may be modified as follows For example, in Fig 1, the first terminal plate 2 may be formed of a base portion and a terminal portion 7, wherein the base portion has a plan cross section substantially U-shaped with the front opening, and the terminal portion 7 is continually and integrally formed rearwardly from the base portion In this case, the second terminal plate 1 is made of a member disposed to cover the front opening of the first terminal plate 2, wherein an upper end portion thereof is held between upper end portions of the base portion of the first terminal plate 2, and a lower end portion is held between lower end portions of the base portion of the first terminal plate 2.
(EXAMPLE APPLICATION TO A SWITCHING DEVICE) Fig 13 shows a wiring accessory employing the connectors according to the first and fourth embodiments Fig 14 shows a cross sectional configuration of the aforementioned accessory The wiring accessory illustrated in these figures is a switching device The switching device has a contact terminal connector A as shown in the first embodiment, a terminal connector B as shown in the fourth embodiment, and an on/off element C that can be actuated through user operations The connectors and element are stowed in a stowing concave portion 13 of a wiring-accessory body 11 The switching-device is used to perform on/off operations of a circuit The connectors A and B each have a terminal that is connected to the wire inserted from a lower portion, when viewed in the drawing, of the wiring-accessory body 11 The onloff element C has a movable contact that is connected to andlor disconnected from the terminal of the contact terminal connector A; and it is always connected to the terminal connector B The on/off element C is operated through a reversing handle 31 that can perform seesaw-like operations and a coil spring 32 The wiring-accessory body 11 is coupled to a cover 33 from an upper portion.
As shown in Fig 14, when the reversing handle 31 is operated to be in a slanted state, the movable contact contacts the contact of the connector A, and the switch is thereby closed When the reversing handle 31 is returned to the original state, the on/off element C is also returned to the original state, wherein the movable contact is disconnected from the contact of the contact terminal connector A, and the switch is thereby opened.
The above-described switching device performs on/off operations for one circuit, but a switching device can also be configured to perform on/off operations for three circuits In this case, it is configured to use two contact terminal connectors A, one terminal connector B and one on/off element C For two contact terminal connectors A, connectors as shown in the first and third embodiments are used The on/off element C is operated to move between these contacts of the connectors, thereby performing switching operations for the circuits.
The present invention is not restricted to the configurations of abovedescribed embodiments, but various other modifications may be implemented as long as they do not depart from the scope of the invention, and the invention includes the modifications.
