Technical field
The present invention relates to a kind of fast connection terminal device.
Background technology
Usually, for example in switch or the wall socket, the extensive use fast connection terminal device connects the electric wire that is incorporated in the housing by the electric wire insertion holes that is located in the electrical power wiring assembly housing at electrical power wiring assembly.This conventional fast connection terminal device comprises terminal board, its with switch in the contact or the socket in the wall socket be electrically connected; The locking spring is used for that electric wire (conductor) is electrically connected to terminal board and holds electric wire simultaneously, to prevent that electric wire separately; And release-push, being used to discharge to locking holding of spring, this release-push is operated by the such instrument of screwdriver that for example is inserted in the operation hole that is located in the housing.
But in this conventional fast connection terminal device, the worker is difficult to determine whether electric wire correctly connects, and operator's operation is not easy very much.In addition, because need instrument to operate release-push, it is also inconvenient to discharge electric wire.
Therefore, the present invention proposes a kind of fast connection terminal device, it can discharge holding of locking spring by use manually operated trip lever without instrument, and this trip lever also is used in reference to the connection (for example, seeing Japanese Patent Application Publication No.2006-12634) that electric wire is shown.
As shown in figure 10, this conventional example comprises terminal board 310, locking spring 320 and trip lever 330.This terminal board 310 comprises rectangular body part 311, a pair of contact 312 that extends from a longitudinal edge of main component 311 and the fitting 313 that extends back from another longitudinal edge of main component 311 backwards.This main component 311, contact 312 and fitting 313 are integrally formed by processing rubber-like strip metal plate.Contact 312 has a pair of upper and lower pressing section 312a, the 312b that is used to compress electric wire, and mating part 312c, the end of this mating part by will going up pressing section 312b crooked formation on away from the direction of fitting 313.The perforation 314 that supply lines passes is formed between pressing section 312b and the main component 311, and is corresponding with the electric wire insertion holes 401 of passing the formation of electrical power wiring assembly housing 400 diapires.
Locking spring 320 forms by rubber-like strip metal plate is bent to about J font.Locking spring 320 comprises hook-type conducting piece 321 and the spring part 322 that contacts with fitting 313 with the main component 311 of terminal board 310, and this spring part is about U font from the bottom bend of conducting piece 321.The front end that contacts with electric wire of spring part 322 is used to hold electric wire, is released to prevent electric wire.Locking spring 320 is arranged to make conducting piece 321 to contact with fitting 313 with main component 311 in terminal board 310 and spring part 322 is arranged in the face of contact 312.Front end by spring part 322 presses contact 312 with electric wire, makes to pass between the spring part 322 that electrical wire fastener that electric wire insertion holes 401 inserts is held in the contact 312 of terminal board 310 and locking spring 320, thereby has prevented the release of electric wire.
In aforesaid conventional example, under the state that the wherein electric wire 500 shown in (c) among Figure 10 does not connect, trip lever 300 rotates to certain position (hereinafter referred to as " initial position "), in this position, be engaged part 332 and cooperate (or breech lock) to the mating part 312c of terminal board 310.When trip lever 300 was in this initial position, the front end of spring part 322 of locking spring 320 was pushed part 336 and promotes, with at the direction top offset away from contact 312.At this moment, though trip lever 330 in opposite steering (counter clockwise direction in Figure 10 (c)) by the elastic force elastic biasing of spring part 322, but trip lever 330 still remains on initial position, cooperates with the mating part 312c of terminal board 310 because be engaged part 332.
If the conductor 501 of electric wire 500 is introduced between contact 312 and the spring part 322 by electric wire insertion holes 401, the front end of conductor 501 314 contacts with the part 332 that is engaged of trip lever 330 by boring a hole, and will be engaged upwards promotion of part 332, thereby be engaged part 332 from cooperating 312c to discharge.Trip lever 330 by the elastic force elastic biasing of spring part 322 rotates on described opposite steering, and the front end of spring part 322 contacts with conductor 501, thereby can prevent that electric wire 500 from discharging, and conductor 501 by the elastic force of spring 322 with contact 312 Elastic Contact.Conductor 501 compacted part 312a and 312b are pressing spring part 322, and the pressure of spring part 322 and pressing section 312a, 312b is balanced, thereby electric wire 500 is clamped in therebetween.

Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described.
Fast connection terminal device comprises terminal board 10, locking spring 20 and trip lever 30 according to an embodiment of the invention, shown in Fig. 1-5.
Locking spring 20 forms by elasticity strip metallic plate is bent to about J font.Locking spring 20 comprises hook-shaped conducting piece 21 and the spring part 22 that contacts with fitting 13 with the main component 11 of terminal board 10, and it becomes about U font to form by the bottom bend from conducting piece 21.The front end of spring part 22 contacts with electric wire, and is used to hold electric wire, is released to prevent electric wire.Spring part 22 also has sweep 22a, and it protrudes on the direction (towards the direction of conducting piece 21) away from electric wire.As shown in Figure 5, locking spring 20 in terminal board 10, be configured such that spring part 22 in the face of contact 12 simultaneously conducting piece 21 and main component 11 and fitting 13 the two all contact.In this case, the width of contact 12 is set as the width that is narrower than spring part 22, thus spring part 22 when the direction vertical with the electric wire direction of insertion seen (left and right directions Fig. 1) be exposed on the both sides of contact 12.As shown in Figure 5, the terminal board 10 of structure and locking spring 20 are contained in the terminal board accommodation section 102 as mentioned above, and electrical power wiring assembly is located at for example among the body 100a of the housing 100 of switch or wall socket in this terminal board accommodation section.A pair of electric wire insertion holes 101 is located in the diapire of terminal board accommodation section 102.At electrical power wiring assembly for example in switch or the wall socket, terminal board 10 and the transport element for example contact of switch or the socket of wall socket link to each other, thereby electric wire is electrically connected with the contact of switch or the socket of wall socket by terminal board 10.
In the present embodiment, in each terminal board 10, be provided with two locking springs 20, be used to have the electric wire of other devices.A terminal board 10 and two locking springs 20 are contained in each the terminal board accommodation section 102 that is located at body 100a both sides.As Fig. 2 and shown in Figure 4, a plurality of vertical slots 104 that communicate with terminal board accommodation section 102 are located in two sides of body 100a.Trip lever 30 links to each other with body 100a, limits rib 33 and handlebar 31 are exposed to housing 100 by each groove 104 outside simultaneously.
The a pair of ribs (not shown) that is used for support hinge portion 35 when trip lever 30 rotations is located between the groove 104 and electric wire insertion holes 101 of body 100a.In addition, when trip lever 30 was contained in the terminal board accommodation section 102, the front end of secondary spring 42 contacted with the fitting 13 of terminal board 10.
In the fast connection terminal device of the present invention of as above constructing, when electric wire 200 did not connect, shown in Fig. 5 (a), trip lever 30 rotated to a position (hereinafter referred to as initial position), in this position, be engaged part 43 and cooperate with the mating part 12c of terminal board 10.When trip lever 30 was in its initial position, the spring part 22 of locking spring 20 was pushed part 36 and compresses, thereby the front end of spring part 22 is at the direction top offset away from contact 12.At this moment, though secondary spring 42 bendings that its front end contacts with fitting 13, and trip lever 30 because of the restoring force of secondary spring 42 and spring part 22 at opposite steering (counter clockwise direction among Fig. 5) upper offset, but trip lever 30 remains in initial position, cooperates with the 12c that cooperates of terminal board 10 because be engaged part 43.
In addition, if the conductor 201 of electric wire 200 is introduced between contact 12 and the spring part 22 by electric wire insertion holes 101, shown in Fig. 5 (b), the front end of conductor 201 is engaged part 43 what pass that perforation upwards promotes trip lever 30 after 14, thereby is engaged part 43 from mating part 12c release.So the trip lever 30 of being setovered by the elastic force of spring part 22 and secondary spring 42 is pivoting on opposite steering, thereby the front end of spring part 22 contacts with conductor 201.Therefore, can prevent that electric wire 200 is released.Conductor 201 is by the elastic force and contact 12 Elastic Contact of spring part 22 simultaneously.Conductor 201 compacted part 12a, 12b are pressing spring part 22, and the elastic force of spring part 22 and pressing section 12a, 12b is balanced, thereby electric wire 200 is trapped in therebetween.By this way, when electric wire was finished with being connected of terminal board 10, the handlebar of trip lever 30 31 moved down from initial position.Therefore, the user can confirm visually that whether the connection of electric wire is finished.
Simultaneously, shown in Fig. 5 (d), if handlebar 31 promotes on electric wire 31 connected whiles quilts, trip lever 30 pivots on the clockwise direction in Fig. 5 around the hinge portion 35 that is supported by ribs.Promote the spring part 22 that part 36 compresses locking spring 20, thereby make spring part 22 be become the front end of spring part 22 is separated with conductor 201 by displacement.As a result, can discharge electric wire 200.Simultaneously, in conventional example, if trip lever 330 is handled to discharge the connection of electric wire 500, be engaged part 332 and contact with the conductor 501 of electric wire 500, shown in Figure 10 (a), therefore, trip lever 330 can upwards slide along conductor 501.So, after electric wire 500 is released, is engaged part 332 and no longer cooperates, thereby trip lever 330 gains freedom (referring to Figure 10 (c)) with mating part 12c.Like this, in the time of connecting electric wire 500 again, just need make to be engaged part 332 and to cooperate with mating part 12c and make and be engaged part 332 and turn back to its initial position (referring to Figure 10 (c)) by the manipulation of trip lever 330.
On the contrary, in an embodiment of the present invention, even trip lever 30 is handled, and be engaged part 43 and contact with conductor 201, support is engaged the strutting piece 41 of part 43 towards restriction rib 33 bendings (left upwards in Fig. 5), thereby trip lever 30 can upwards not slide along conductor 201.As a result, after electric wire 200 is released, be engaged part 43 and cooperate naturally, thereby trip lever 30 returns its initial position with mating part 12c.Therefore, do not need as in the conventional example after discharging electric wire 200 once more to make by operation trip lever 330 to be engaged part 43 and to cooperate with mating part 12c, this makes that electric wire connection work is simple.In addition, restriction rib 33 is located at the front of strutting piece 41 respectively, and restriction rib 33 can prevent the crooked scheduled volume (this can cause for example strutting piece 41 plastic deformations) that surpasses of strutting piece.If rib 33 without limits, the terminal board 10 that is contained in the terminal board accommodation section 102 just is exposed to the outside by the groove 104 that is formed at housing 100 sides.But in this embodiment, because groove 104 is covered by restriction rib 33 as shown in Figure 4, terminal board 10 can not expose.If the front end of restriction rib 33 extends up to shown in Fig. 6 (a) and is engaged near the part 43, restriction rib 33 can contact being engaged part 43 places with trip lever 30, thereby can further prevent the plastic deformation of strutting piece 41.If the front end of restriction rib 33 is connected with each other, shown in Fig. 6 (b), then can strengthen the intensity of restriction rib 33.
In the present invention, the reason that secondary spring 42 is set is described following.If the connection of electric wire 200 is finished as mentioned above, be engaged part 43 and throw off, and trip lever 30 pivots on opposite steering with mating part 12c.Though electric wire 200 has been connected, the spring part 22 of locking spring 20 does not contact with promotion part 36.Like this, when housing 100 was arranged to make the electric wire insertion holes 101 that is formed in its bottom surface to face up, if there is no secondary spring 42, and trip lever 30 can be because its deadweight and moving on steering, and this makes that the indication that electric wire has been connected is unclear.In this embodiment, because trip lever 30 passes through secondary spring 42 at opposite steering upper offset always, even when housing 100 keeps the bottom surface up as mentioned above, can prevent that also trip lever 30 from moving on steering, because under the state that is engaged part 43 and mating part 12c disengagement, can prevent trip lever because it moves from focusing on the steering.In this way, can keep electric wire is connected completed good indication.
In an embodiment of the present invention, trip lever 30 comprises the lever main body that is molded as by synthetic resin and the counterpart that is made of metal 40 and strutting piece 41.But, can use for example to have elastomeric resin material and integrally moulded counterpart 40 ' of lever main body and strutting piece 41 ' (referring to Fig. 7 (a)).Alternatively, when single resin material can not satisfy the required intensity of the required elasticity of counterpart 40 and strutting piece 41 and lever main body, trip lever 30 can use bimodulus technology to come molded (referring to Fig. 7 (b)) by suitable resin material.It in the lever main body is the metalwork 44 that comprises integrally molded counterpart 40 and strutting piece 41 can be inserted things and be molded into (with reference to figure 7 (c)) in the lever main body that replacement inserts with counterpart 40 and strutting piece 41 that things are molded into.In addition, metalwork 44 link to each other with lever main body with welding (with reference to figure 7 (d)) that also can for example bond by suitable method.
In addition, as in the conventional example by the synthetic resin material under the situation that secondary spring and lever main body is integrally molded, secondary spring may creep when secondary spring keeps initial position for a long time in warehouse etc.But in an embodiment of the present invention, secondary spring 42 is made by the metal leaf spring, and its inserted mode system is in the lever main body of the trip lever of being made by synthetic resin 30.Therefore, can prevent secondary spring 42 contingent creep when remaining in initial position for a long time, therefore, may keep 30 pairs of electric wires of trip lever to connect completed good indication.
In an embodiment of the present invention, only be provided with a secondary spring 42.But,, shown in Fig. 9 (a), can further prevent trip lever 30 securely because it moves from focusing on the opposite steering if when each compressed part 36 is all given prominence to secondary spring 42.In addition, if these secondary springs 42 connect at its front end, shown in Fig. 9 (b), can prevent the distortion of secondary spring 42.
But because the load that the spring part 22 of locking spring 20 produces is applied on a pair of promotion part 36 of trip lever 30, this may be towards displacement each other (disconnection) to promoting part 36.Like this, in an embodiment of the present invention, will be located in the lever main body,, thereby can prevent to promote part 36 towards displacement each other so that this is to 36 interconnection of promotion part with the coupling part 37 that handlebar 31 be arranged in parallel.In addition, no matter trip lever 30 be in initial position (seeing Fig. 8 (a)) still be in the indication electric wire connect completed position (seeing Fig. 8 (b)), coupling part 37 all has such shape and size, and when the direction that is inserted into from electric wire 200 was seen, it did not all have with electric wire insertion holes 101 overlapping.
Although the present invention is the description of carrying out with regard to specific embodiment, it will be understood by those skilled in the art that and under the prerequisite of the scope of the invention that does not depart from claim and limited, to make various modifications or variation.
