Embodiment
Fig. 1 shows according to a jockey 1 of the present invention.This device 1 comprises a contact 2 that is designed to be installed on the bus 3.Bus 3 is preferably admitted several all contacts as shown in the reference numeral 2, and all contacts are fixed on the bus 3 in an identical manner.Bus 3 for example is a rectangle, and all contacts as shown in the reference numeral 2 are connected along the long limit of this rectangle.Bus 3 is for example made by solid copper spare and is obtained by cutting down from a copper coin, and this cutting member is then by chemical etching.
Bus 3 can be connected in the electric current distributor box.For this reason, it comprises a wiring surface 4.Described wiring surface 4 is by from metallic plate cutting down and crookedly obtain to form at least two 90 ° of angles, thus make plate 3 with it the bottom of fastening distributor box parallel.
Contact 2 is a two point, and it comprises flexible prongs 5 and at least one following flexible prongs 6 at least one.In the embodiment shown in Figure 2, each of flexible prongs 5,6 is configured to face with each other.At each free end 7,8 place an opening 9 is arranged.This opening 9 is used to admit a contact plug (not shown), and described contact plug is designed to and installs 1 effect mutually.This contact plug has for example elongated flat shape, thereby in it inserted opening 9, free end 7 contacted with the upper surface of contact plug, and free end 8 contacts with the lower surface of this contact plug.Two point 2 is formed by having last free end 7 and following free end 8.
Described flexible prongs is for example by obtaining from also crooked down this cutting member of metallic plate cutting.In this case, upper tine 5 comprises the first 10 that is secured on the bus 3, and a tongue piece 11 extends in this first, and therefore the length of tongue piece 11 give its certain flexibility greater than width.Tongue piece 11 is bent, thereby it has concave shape when seen in cross-section.Crooked or the pre-tensioned portion of tongue piece 11 forms free end 7.
Similarly, lower tine 6 comprises and 10 similar firsts 10 ' that it is designed to be fixed on the bus 3, also comprises the tongue piece 11 ' with female shapes.Tongue piece 11 ' for example has the shape of symmetrical plane 12 and tongue piece 11 symmetries relatively.Tongue piece 11 ' has female shapes equally, makes that tongue piece 11 ' is distributed on the either side of symmetrical plane 12 symmetrically when first 10 ' and 10 links together.Tongue piece 11 does not contact each other with 11 ', and they are freely.The pre-tensioned portion of tongue piece 11 ' therefore forms free end 8 down.
Tongue piece 11 and 11 ' total symmetrical plane 12 that is parallel to extend, and this plane 12 and the opening 9 that is formed between two free ends 7 and 8 intersect vertically.They form a clip, by the insertion of contact plug, and described clip strain.
More specifically, described free-ended shape is such, makes each free end have first elbow of relative opening 9, makes limit 105 and 106 outwards open from opening 9.These elbows make that also flexible prongs can be close to each other and opening 9 is provided, and the minimum range between two flexible prongs in opening 9 places 5,6 is littler than the average thickness of the contact plug that is used for being inserted in opening.
In the time of in contact plug is inserted into opening 9, described flexible prongs is stressed, and keep this power, and the repeatedly action that connects and disconnect can cause described fork distortion and no longer can return their resting position, in described resting position, the interval of two forks is little more many than the average thickness of standard contact plug.For this reason, device 1 according to the present invention comprises a spring 13.
Described spring 13 surrounds flexible prongs at least in the concave portions of flexible prongs, and forces flexible prongs to return their resting position when not having contact plug to be inserted between the flexible prongs.On the other hand, when contact plug was inserted between the flexible prongs, the existence of spring 13 had increased the contact pressure of these flexible prongs.
Spring 13 is inserted in the groove 14 that is formed at each flexible tines.Especially, upper tine 5 comprises a groove 14 ', and lower tine 6 also comprises a groove 14 ".Groove 14 ' and 14 " be formed at two gaps between the fork and be communicated with.Spring 13 has U type shape, thereby it has two shanks 15,16 respectively.Spring 13 preferably has the axis of symmetry, thereby it can be with in any shank 15 or 16 insertion grooves 14.In fact, the width of groove 14 just enough holds spring 13.Shank 15 and 16 end are supported on respectively on the outer surface 17 and 18 of flexible prongs 5 and 6.
According to first embodiment, spring 13 is shaped as a horseshoe and with U type shape and downcuts from metallic plate.Being of uniform thickness of the metallic plate that the width of groove 14 almost therefrom cuts with spring 13.In order to guarantee that spring 13 keeps this shape, groove 14 ' and 14 " all only be formed on upper surface 17 and 18.They neither are expanded to the zone of opening limit 105,106, also are not expanded to opening opposing 9.Therefore spring 13 is inserted into the groove 14 from one of them outer surface.In order to be maintained in the groove, each shank 15,16 includes a protruding wall 19 and 20. Protruding wall 19 and 20 is provided with relative to one another and is designed to be respectively and groove 14 ' and 14 " the front match.
For the spring of making according to first embodiment 13 is installed, spring 13 vertically be arranged on one of them outer surface (for example outer surface 17) above.U die cavity 21 is so arranged, and makes it leave mouth 9 farthest.Shank 15 and 16 is imported in the groove 14, and chamber 21 is remained on the outside of groove.Shank 15 and 16 is so placed, and makes described two protruding walls be supported on groove 14 ' and 14 respectively " the limit on.Effect is will form the little width that limits groove and be set to the approaching limit of near-earth and opening as far as possible 9.Not shown these limits in Fig. 2.
At last, for the installation of the spring 13 of finishing Horseshoe, power is applied on the narrow limit in the chamber 21 that protrudes on the outer surface 17, so that to torque of its transmission.When the leg position of U type spare overlaps with the inwall that is formed at the gap between the fork 5 and 6, spring reach one stablize, the position of balance.Because spring 13 is longer slightly than the length of groove 14, it remains on its equilbrium position.
Such U type spring provides a restriction fork the 5 and 6 undue power of launching, and described power is the function of the shape and its incurvature in chamber 21.
According to second embodiment, spring 13 also forms a pliers.It is provided with a rectangle handle 22 for this reason, extends two branches 23 and 24 that are provided with relative to one another from described rectangle handle.Spring 13 is by obtaining down from the metallic plate cutting with X type shape roughly.Then, described X type spare is bent, and makes to be formed centrally handle 22 in the intersection of two arms of X.The branch of X type spare is folded in couples, so that form two branches 23 and 24.
In this modification, similarly spring 13 has symmetrical plane, thereby can be with in spring 13 insertion grooves 14, and tube seat is not positioned at upper surface or lower surface.Then, as shown in Figure 6, begin to be inserted into from opening 9 according to the spring 13 of this embodiment.In this case,, groove 14 ' and 14 different with first embodiment " with open limit 105 and 106 and be connected so that allow handle 22 to pierce into the bottoms that are formed at two gaps between the fork 5 and 6.
In the side of handle 22, the interval ratio open 9 between the branch 23 and 24 is big a lot.This means that branch 23 and 24 is all by above the outer surface when spring 13 is mobile towards the bottom, gap.In this case, top set 23 extends through outer surface 17, and inferior division 24 extends through outer surface 18.
In addition, branch 23 and 24 is all by so crooked, makes distance between these two branches along with reducing with the increase of handle 22 distances.Especially, branch is bent, and makes them surround the concave shaped portion of fork 5 and 6.Therefore, when spring 13 is moved when handle 22 abuts against the bottom of groove 14, crooked branch is restriction fork progressively by exerting pressure on the outer surface of fork.But when handle 22 reached its rest position, branch 23 and 24 no longer limited fork 5 and 6, and this is because they are in a position, and they surround fork 5 and 6 and no longer apply any power in this position.Branch 23 and 24 is also by pre-tensioning, and they promote fork 5 and 6 to return their resting position.
In a preferred embodiment, groove 14 is formed on the central authorities of each outer surface 17 and 18.Especially, groove 14 ' is formed on the central authorities of outer surface of upper, groove 14 " be formed on the central authorities of lower external face.Groove 14 ' and 14 " relative free end 17 and 18 symmetrical plane 25 be provided with.This symmetrical plane is perpendicular to plane 12, and it is parallel to the main prolongation axis extension of fork 5 and 6 in addition.In fact, symmetrical plane 25 is parallel with the longest edge of these forks.
Fig. 7 is a full view, is directed according to the jockey that has two point 21 of second embodiment of the invention, thereby contacts with the both sides of a flat contact plug 26.
