Summary of Invention

Technical Problem

The operation of making the shafts protruded from the connector body to be fitted in the shaft bearing holes formed in the arm side plates while the two arm side plates of the lever are expanded is not an operation that can be easily performed, but an operation that requires time and skills. Particularly, when an wire cover is installed to the rear of connector body, because the gap between the wire cover and the lever becomes small, the wire cover interferes, and there is a problem that it becomes harder to install the lever.

It is therefore one advantageous aspect of the present invention to provide a lever assembling device for a connector with a lever so that the lever can be easily assembled to a connector body.

Solution to Problem

According to one advantage of the invention, there is provided a lever assembling device for a connector with a lever, for assembling the lever of the connector to a connector body, the connector comprising

the connector body, which includes shafts protruded from two outer side surfaces thereof, and

the lever, which has a pair of arm side plates disposed along two outer side surfaces of the connector body and a joining part joining the pair of arm side plates to have a U-shaped section, which is pivotably installed to the connector body by making shafts to be fitted in shaft bearing holes respectively formed in the pair of arm side plates, and which is pivoted to fit the connector body with the mating connector by leverage when the connector body is to be fitted with a mating connector,

wherein the lever assembling device comprises:

a base configured to hold the connector body in a state the connector body is set from above; and

a lever insertion jig, which is installed to the base from above to cover the connector body in a state where the connector body is set onto the base from above, which includes, fitting guides configured to guide the lever so that the shafts are fitted in the shaft bearing holes,

wherein, when the lever is pushed down from above to the connector body which is held on the base, the fitting guides slide with respect to inner surfaces of the pair of arm side plates of the lever as the lever is pushed down so as to make the pair of arm side plates to be elastically deformed outwards to widen a distance between the two arm side plates, and

wherein the lever insertion jig is moved in a detaching direction when the shafts are disposed in the shaft bearing holes so that the fitting guides are moved away from the position where the two arm side plates are slid with respect to the two arm side plates, thereby two arm side plates are restored to original positions and the shafts are fitted in the shaft bearing holes.

The lever insertion jig may include first detachment leading parts which make the lever insertion jig to be moved in the detaching direction by abutting against outer edges of the two arm side plates which is further pushed down to the connector body after the shaft bearing holes arrive at positions where the shafts can be fitted as a result of having pushed down the lever to the connector body.

The fitting guides may include second detachment leading parts which generate an assistant force to make the lever insertion jig to be further moved in the detaching direction due to an elastic restoring force when the two arm side plates are restored to the original positions since the lever insertion jig is moved in the detaching direction with the action of the first detachment leading parts.

The base includes a rise preventing wall which prevents a rise of the connector body at the time of assembling the lever. The lever assembling device may be configured such that at the rear of the connector body, a wire cover is installed which leads wires drawn from the rear of the connector body to a predetermined direction, and the lever insertion jig is configured to be installed to the base to be over the wire cover from above the connector body after the wire cover is installed.

Advantageous Effects of Invention

According to the lever assembling device of the construction of the present invention, because the base for setting the connector body is provided in addition to the lever insertion jig for expanding the arm side plates of the lever outward, the connector body can be held stably at the time of assembling the lever, and the assembly of the lever becomes easy to be performed. By installing the lever insertion jig to the base from above the connector body which is set onto the base, the fitting guides of the lever insertion jig can be positioned right above the shafts which are protruded from the two outer side surfaces of the connector body.

Therefore, by pushing down the lever to the connector body from above the lever insertion jig, the two arm side plates of the lever can be slid along the fitting guides of the lever insertion jig so that the two arm side plates of the lever 2 can be elastically deformed outwards to widen the distance between the two arm side plates.

Thus, after the shaft bearing holes of the two arm side plates arrive at positions where the shafts of the connector body can be fitted, by moving the lever insertion jig in the detaching direction, the fitting guides of the lever insertion jig can be moved away from the positions where the arm side plates are slid. Thereby, the arm side plates which are elastically deformed can be elastically restored to the original positions, the shafts of the connector body can be fitted in the shaft bearing holes of the arm side plates, and the assembly of the lever can be completed.

According to the lever assembling device of the construction of the invention, because the lever insertion jig can be moved in the detaching direction by further pushing down the lever after the shaft bearing holes of the two arm side plates arrive at positions where the shafts of the connector body can be fitted, the operation of detaching the lever insertion jig can be easily performed.

According to the lever assembling device of the construction of the invention, because an assistant force which makes the lever insertion jig to be moved in the detaching direction is generated due to the elastic restoring force of the two arm side plates, the operation of detaching the lever insertion jig can be more easily performed. According to the lever assembling device of the construction of the invention, because the connector body can be pressed down without being raised at the time of assembling the lever, an excellent operativity can be secured.

According to the lever assembling device of the construction of the invention, even when the wire cover is installed to the rear of the connector body, the lever insertion jig can be installed to the base over the wire cover. Thus, even when the gap between the connector body and the lever becomes small since the wire cover is installed, the lever can be assembled to the connector body easily. According to the present invention, because the base and the lever insertion jig are included, the lever can be assembled to the connector body easily. In particular, even when the wire cover is installed to the rear of the connector body, the lever can be easily assembled with the lever insertion jig. Brief Description of Drawings

Description of Embodiments

Below, an embodiment of the invention is described with reference to the figures. Fig. 1 shows the constructions of a base and a lever insertion jig which are component elements of a lever assembling device of the embodiments, a connector body with a wire cover and a lever which is installed to the connector body. Fig. 2 shows the base, the lever insertion jig, the connector body with the wire cover and the lever in an assembling order.

As shown in Fig. 1 , a lever 20 to be installed to a connector body 10 with a wire cover 30 is to be assembled. A base 50 and a lever insertion jig 60 are prepared as devices for assembling the lever 20 to the connector body 10.

The connector body 10 accommodates a plurality of metal terminals (not shown in the figures) inside a connector housing 11 made of resin, and has shafts 3, which are protruded for assembling the lever 20, at the centers of two wider side surfaces of the connector housing 11 which has a roughly cubical shape. The wire cover 30 is installed to the rear (the upper part in Fig. 1) of the connector body 10 opposite to the side where a mating connector is fitting with. The wire cover 30 is so constructed that wires drawn out from the rear end of the connector body 10 are bent laterally by a curving cover part 31 , and led to a predetermined direction by a derivation cover part 32.

The lever 20 is constructed in order to be installed to the connector body 10 from behind the connector body 10 to which the wire cover 30 is installed. The lever 20 has a pair of arm side plates 21 , which are disposed along two side surfaces of the connector body10, and a joining part 22 which joins the pair of arm side plates 21 and has a U-shaped section. The pair of arm side plates 21 are provided with shaft bearing holes 23, respectively. By making shafts 13 protruded from two side surface of the connector body 10 to be fitted in the shaft bearing holes 23 of the pair of arm side plates 21 , the lever 20 is pivotably installed to the connector body 10. Thus, the lever 20 is adapted to be pivoted, when the connector body 10 is to be fitted with the mating connector, to make the connector body 0 to be fitted with the mating connector by leverage.

The device for assembling the lever 20 to the connector body 10 includes a base 50 which holds the connector body 10 when the connector body 10 is set from above, and a lever insertion jig 60 which is installed to the base 50.

The base 50 has a roughly cubical box-like shape, and has a pair of right and left side walls 51 which are parallel to each other, a front wall 52 which joins front end edges of the pair of side walls 51 , and a connector carrying plate 53 whose circumferential edges are supported by the two side walls 51 and the front wall 52 and which is horizontally disposed at a position lowered than the upper ends of the two side walls 51 and the front wall 52. The top surface of the connector carrying plate 53 becomes a surface which carries the front surface (surface of the side where the mating connector is fitted with) of the connector body 10 which is pushed downwards between the side walls 51 from above.

Installing parts 54 for the lever insertion jig 60 are provided at the rear of the connector carrying plate 53 (the side apart from the front wall 52) at the upper parts of the inner surfaces of the right and left side walls 51. The jig installing parts 54 are constructed by rail-like stepped portions. From the upper end of the inner surface of the front wall 52, a rise preventing wall 52a is protruded for preventing a rise of the connector body 10 after the connector body 10 is placed on the connector carrying plate 53 (refer to Figs. 2A and 2B).

On the other hand, the lever insertion jig 60 is installed from above to the base 50 to cover the connector body 10 after the connector body 10 is set onto the base 50 from above, as shown in Fig. 4. As shown in Figs. 1 , 3A and 3B, the lever insertion jig 60 has a pair of right and left side plates 61 and a joining plate 62 which joins the upper ends of the pair of right and left side plates 61. The pair of right and left side plates 61 are formed to have such a size that the lever insertion jig 60 can be inserted between the inner surfaces of the right and left side walls 51 of the base 50, and the lower ends of the pair of right and left side plates 61 can be carried on the jig installing parts 54 formed at the upper parts of the inner surfaces of the side walls 51 of the base 50.

At the front ends of the right and left side plates 61 of the lever insertion jig 60, projection-shaped fitting guides 63 are protruded, respectively. At the front end edges of the right and left side plates 61 of the lever insertion jig 60, first guiding ramps 64 and second guiding ramps 65 are provided sequentially from above at positions farther outwards than the outer side surfaces of the fitting guides 63. The fitting guides 63 of the lever insertion jig 60 are parts that guide the lever 20 so that when the lever 20 is pushed down from above to the connector body 10 which is held on the base 50, the inner surfaces of the pair of arm side plates 21 of the lever 20 are slid as the lever 20 is pushed down to make the pair of arm side plates 21 to be elastically deformed outwards to widen the distance between the two arm side plates so that the shafts 13, which are protruded from the two outer side surfaces 12 of the connector body 0, are fitted in the shaft bearing holes 23, which are formed in the two arm side plates 21. For this purpose, first inclined surfaces 63a which expand the arm side plates 21 of the (ever 20 outwards are provided at the upper outer side surfaces of the projection-formed fitting guides 63.

The right and left projection-formed fitting guides 63 make the shafts 13 to be fitted in the shaft bearing holes 23, by making the lever insertion jig 60, after the shafts 13 of the connector body 10 are in the shaft bearing holes 23 of the two arm side plates 21 , to be moved in a detaching direction to be away from the position where the two arm side plates 21 are slid to make the two arm side plates 21 to be restored to the original positions. The lower second guiding ramps 65 formed at the front end edge of the right and left side plates 61 of the lever insertion jig 60 are parts that function as first detachment leading parts which make the lever insertion jig 60 to be moved in a detaching direction (arrow C direction in Fig. 7) by abutting against the outer edges of the two arm side plates 21 of the lever 20 which is further pushed down to the connector body 10 after the shaft bearing holes 23 of the two arm side plates 21 reach positions where the shafts 13 of the connector body 10 can be fitted as a result of having pushed down the lever 20 to the connector body 10. At the front outer side surfaces of the fitting guides 63, second inclined surfaces (second detachment leading parts) 63b are provided which generate an assistant force to make the lever insertion jig 60 to be further moved in the detaching direction due to an elastic restoring force when the two arm side plates 21 are restored to the original positions since the lever insertion jig 60 is moved in the detaching direction (arrow C direction in Fig. 7) with the action of the second guiding ramps 65 that function as the first detachment leading parts.

The functions of the above-mentioned first inclined surfaces 63a, first guiding ramps 64, second guiding ramps 65 (the first detachment leading parts), second inclined surfaces 63b (the second detachment leading parts) will become clear by describing the following operations.

Next, operations are described.

When the lever 20 is to be assembled to the connector body 10 with the wire cover 30, the following steps are performed.

First, as shown in Fig. 4, the connector body 10 is set onto the base 50. That is, the connector body 10 is inserted between the right and left side walls 51 of the base 50 with the front surface (surface where the mating connector is fitted) of the connector body 10 facing downwards, and the front surface of the connector body 10 is placed on the connector carrying plate 53. Thereby, as shown in Figs. 12A and 12B, the connector body 10 is kept from rising during operations by the rise preventing wall 52a of the base 50. In this state, the lever insertion jig 60 is installed to the base 50. In this case, the lever insertion jig 60 is installed over the connector body 10 and the wire cover 30.

Then, as shown in Fig. 5, the lever 20 is pushed down from above in an arrow A direction with the distal ends of the arm side plates 21 facing downwards and with the joining part 22 facing upwards. Thereby, while a part of the outer edges of the arm side plates 21 of the lever 20 is guided along the first guiding ramps 64 of the lever insertion jig 60, the lower ends of the arm side plates 21 ride on the first inclined surfaces 63a (refer to Fig. 2) of the fitting guides 63 of the lever insertion jig 60. The arm side plates 21 are deformed elastically outwards as the arm side plates 21 ride on the first inclined surfaces 63a so that the distance between the right and left arm side plates 21 is widened.

When the lever 20 is pushed down in the arrow A direction, as shown in Fig. 6, while a part of the circumferential edges of the arm side plates 21 is guided to follow the second guiding ramps 65 of the lever insertion jig 60 at this time, the central parts of the arm side plates 21 ride on the fitting guides 63 of the lever insertion jig 60. Thereby, the shaft bearing holes 23 of the arm side plates 21 which are expanded comes to arrive at positions of the shafts 13 of the connector body 10. In this state, when the lever 20 is further pushed down in the arrow A direction, as shown in Fig. 7, when the outer circumferential edges of the lever 20 which are being pushed down hit the second guiding ramps 65, the lever insertion jig 60 is pushed and moved in an arrow C direction that is a detaching direction. Thereby, the fitting guides 63 of the lever insertion jig 60 will gradually deviate from the positions where the two arm side plates 21 are slid, and with the deviation the two arm side plates 21 are restored to the original positions and the shafts 13 are fitted in the shaft bearing holes 23.

In the process that the arm side plates 21 are restored to the original positions, as shown in Fig. 8, when the lever 20 is pivoted in an arrow B direction, a part of the outer circumferential edges of the arm side plates 21 are slid on the second inclined surfaces 63b (the second detachment leading parts) of the fitting guides 63 so that the assistant force to make the lever insertion jig 60 to be further moved in the detaching direction (an arrow C direction) is generated. Further, with the pivoting of the lever 20, the distal ends of the lever 20 push and move the lever insertion jig 60 in the detaching direction (the arrow C direction). As shown in Fig. 9, by making the lever 20 to be pivoted to a boundary position, the lever insertion jig 60 can be moved a lot in the detaching direction. Thereby, the arm side plates 21 of the lever 20 are completely separated from the fitting guides 63, and the arm side plates 21 are completely restored to the original positions with the separation so that the shafts 13 are fitted in the shaft bearing holes 23 surely.

Thereby, the assembly of the lever 20 is completed.

After the assembly is completed, the lever insertion jig 60 is removed upwards, and the connector body 10 with the lever 20 is removed from the base 50 so that the operations are finished.

By using the base 50 and the lever insertion jig 60 which are lever assembling devices in this way, the lever 20 can be easily installed to the connector body 10. In this case, because the base 50 for setting the connector body 10 is provided in addition to the lever insertion jig 60 for expanding the arm side plates 21 of the lever 20 outward, the connector body 10 can be held stably at the time of assembling the lever 20, and the assembly of the lever 20 becomes easy to be performed.

By installing the lever insertion jig 60 to the base 50 from above the connector body 10 which is set onto the base 50, the fitting guides 63 of the lever insertion jig 60 can be positioned right above the shafts 13 which are protruded from the two outer side surfaces 12 of the connector body 10. Therefore, only by pushing down the lever 20 to the connector body 0 from above the lever insertion jig 60, the two arm side plates 21 of the lever 20 can be slid along the fitting guides 63 of the lever insertion jig 60 so that the two arm side plates 21 of the lever 2 can be elastically deformed outwards to widen the distance between the two arm side plates 21. Thus, after the shaft bearing holes 23 of the two arm side plates 21 arrive at positions where the shafts 13 of the connector body 0 can be fitted, by moving the lever insertion jig 60 in the detaching direction, the fitting guides 63 of the lever insertion jig 60 can be moved away from the positions where the arm side plates 21 are slid. Thereby, the arm side plates 21 which are elastically deformed can be elastically restored to the original positions, the shafts 13 of the connector body 10 can be fitted in the shaft bearing holes 23 of the arm side plates 21 , and the assembly of the lever 20 can be completed.

Particularly/ in this embodiment, by providing the second guiding ramps 65 (first detachment leading parts) at the front end edge of the lever insertion jig 60, because the lever insertion jig 60 can be moved in the detaching direction by further pushing down the lever 20 after the shaft bearing holes 23 of the two arm side plates 21 arrive at positions where the shafts 13 of the connector body 10 can be fitted, the operation of detaching the lever insertion jig 60 can be easily performed.

In terms of this point, the above embodiment is compared with a case that there are not the second guiding ramps 65 (the first detachment leading parts). Fig. 10A is a side view which shows that the lever insertion jig of the present embodiment is installed to the base which holds the connector body. Fig. 10B is a side view which shows that a lever insertion jig of a comparative example is installed to the base which holds the connector body. Figs. 11A and 11B are figures corresponding to Figs. 10A and 10B, in which Fig. 11 A is a side view which shows that in the case of the present embodiment, by pushing down the lever to assemble the lever, the lever insertion jig is moved in the detaching direction (the arrow C direction). Fig. 11 B is a side view which shows that in the case of the comparative example, it is necessary to move the lever insertion jig by hands (an arrow D) because the lever insertion jig will not be moved in the detaching direction by pushing down the lever to assemble the lever.

As shown in Fig. 10A, in the case of the present embodiment, there are the second guiding ramps 65 (the first detachment leading parts) at the front end edge of the lever insertion jig 60, but in the case of a comparative example shown in B, there are not the second guiding ramps 65 (the first detachment leading parts) at the front end edge of the lever insertion jig 60. Therefore, when the lever 20 is to be assembled, in the case of the present embodiment as shown in Fig. 11 A, by pushing down the lever 20 in the arrow A direction to assemble the lever 20, the lever insertion jig 60 is moved in the detaching direction (the arrow C direction). In contrast, in the case of the comparative example as shown in Fig. 11 B, only by pushing down the lever 20 to assemble the lever 20, the lever insertion jig 60 will not be moved in the detaching direction. Thus, it is necessary to move the lever insertion jig 60 by hands (the arrow D).

Thus, operations become troublesome, since it is necessary to move the lever insertion jig 60 in the detaching direction actively by hands. However, in the case of the present embodiment, since the lever insertion jig 60 can be moved in the detaching direction by merely pushing down the lever 20, operations can be simplified.

Because an assistant force which makes the lever insertion jig 60 to be moved in the detaching direction is generated due to the elastic restoring force of the two arm side plates 21 of the lever 20 since the second inclined surfaces 63b (the second detachment leading parts) are provided at the fitting guides 63, the operation of detaching the lever insertion jig 60 can be more easily performed. In this embodiment, because the connector body 10 can be pressed down without being raised at the time of assembling the lever 20 by protruding the rise preventing wall 52a from the base 50, an excellent operativity can be secured.

In this embodiment, even when the wire cover 30 is installed to the rear of the connector body 10, the lever insertion jig 60 can be installed to the base 50 over the wire cover 30. Thus, as shown in Figs. 2A and 12B, even when the gap between the connector body 10 and the lever 20 becomes small since the wire cover 30 is installed, the lever 20 can be assembled to the connector body 10 easily.

Even when there is no wire cover as shown in Fig. 13, by covering the connector body 10 from above with the lever insertion jig 60 over the connector body 10, the wires W can be prevented from being caught at the time of assembling the lever 20. Thus, the lever 20 can be easily assembled. The present invention is not restricted to the above-described embodiments, and suitable modifications, improvements and the like can be made. Moreover, the materials, shapes, dimensions, numbers, installation places, and the like of the components in the above embodiments are arbitrarily set as far as the invention can be attained, and not particularly restricted.

The present application is based on Japanese Patent Application No. 2012-033187 filed on February 17, 2012, the contents of which are incorporated herein by way of reference.
