Detailed Description
Hereinafter, a structural example of a connector according to the present invention will be described with reference to the drawings, but the present invention is not limited thereto.
fig. 1 to 3 show a process of connecting a cable to a connector, and fig. 4 shows an example of a component configuration.
the connector shown in fig. 1 is a three-wire connection type, but the number of cables connected to a terminal block or the like is not limited.
the connector includes a housing 11a in a housing 11, and a connection portion between a terminal 12 and a cable 1 is disposed in the housing 11 a.
Fig. 2 shows the cable 1 before connection to the connector.
The structure will be described with reference to fig. 4.
As shown in fig. 4(b), the terminal 12 for electrical connection to another device includes a base portion 12a that contacts the side portion of the core wire 1a of the cable 1, and a terminal portion 12b that is connected to another device.
On both sides of the base portion 12a, guide portions 12f, 12g of the cable core 1a and guide portions 12d, 12e of an indicator 15 described later are provided.
the rod-like pointer section 15c is provided upright in a substantially L-shape from the base section 15a of the pointer 15, and is provided with an insertion through hole 12c for inserting the pointer section 15c therethrough.
The elastic member 13 is for energizing the core wire 1a of the cable toward the base portion 12a of the terminal 12, and as shown in fig. 4(c), the elastic member 13 is provided with a pressing portion 13c and a locking portion 13e, and the pressing portion 13c is bent from the substrate portion 13a by the folded portion 13b, and further, the tip thereof is folded back toward the substrate portion 13a side to form the locking portion 13 e.
the locking portion 13e has a door structure shape having an insertion opening 13d for the core wire of the cable 1, and locks the side portion of the core wire 1a inserted through the insertion opening 13d to be energized to the terminal.
The spring portions 13f and 13g are provided for energizing the indicator 15 in the retracting direction, and the spring portions 13f and 13g are provided on both sides of the base plate portion 13 a.
the indicator 15 is made of resin, and as shown in fig. 2, is located below the base portion 12a of the terminal 12, the sliding portion 11e is provided at the bottom of the housing portion 11a of the housing 11, and the base portion 15a moves forward or backward along the sliding portion 11 e.
An abutting portion 15b pressed by a cable core is provided at a rear portion of the base portion 15a on the side of the connection hole 11b, and a pointer portion 15c is provided standing upward from a front end side of the base portion 15 a.
The movement of the pointer section 15c is visually checked from the check window 11c of the housing 11 as a display section 15d at the distal end portion thereof.
Specifically, in a state before the core wire 1a of the cable 1 is inserted and connected, the pointer section 15c of the indicator 15 is stored in the storage section 11d provided in the housing 11, and the display section 15d at the tip end of the pointer section 15c is not visible through the confirmation window 11c of the housing 11.
When the cable 1 is inserted from the connection hole 11b of the housing 11 toward the inside as shown in fig. 2(c), the distal end portion of the core wire 1a abuts against the abutting portion 15b of the indicator 15 as shown in fig. 3, and the indicator advances.
Thus, the abutting portion 15b of the indicator 15 and the pointer section 15c (display section 15d) are coupled by the base portion 15a, and therefore the pointer section 15c moves forward from the state of being housed in the housing section 11 d.
Therefore, if the cable 1 is not inserted to the set depth, the display portion 15d does not appear in the confirmation window 11c, and therefore, it is possible to confirm whether or not the cable 1 is inserted to the set depth with the confirmation window 11 c.
thus, even if the connection portion between the cable 1 and the terminal 12 is located inside the housing, the connection can be easily confirmed by the indicator.
in the present embodiment, in order to allow the amount of movement of the indicator 15 to follow the insertion depth of the core wire 1a of the cable, as the structure of the indicator 15, as shown in fig. 4(d) and (e), the side portions 15g and 15h are slid along a slide groove portion (not shown) provided in the side surface of the housing portion 11a of the housing 11, the side portions 15g and 15h are provided on both sides of the base portion 15a, and as shown in fig. 5, the indicator 15 is provided with inclined surface portions 15e and 15f having a width that is increased toward the abutting portion 15b side so that the indicator 15 is energized in the backward direction (the housing direction of the pointer portion 15 c) by the spring portions 13f and 13g formed on both sides of the elastic member 13.
The energizing structure is not limited to this, and may be constituted by a coil-shaped spring 16 as shown in fig. 6, for example.
Next, the cable connecting operation is explained.
In the connector according to the present embodiment, the core wire 1a of the cable 1 is inserted between the locking portion 13e of the elastic member 13 and the base portion 12a of the terminal 12, and is electrically connected by energizing force of the locking portion 13 e.
Then, an operation lever 14 for switching the locking portion 13e between the locked state and the opened state is provided.
As shown in fig. 2, the operating lever 14 is attached to the housing so as to be rotatable via a pivot portion 14 a.
The operation lever 14 includes an operation portion 14c operated by a finger or the like, and an operation portion 14b provided on the opposite side through a pivot portion 14 a.
As shown in fig. 4(a), the elastic member 13 is housed in the housing portion 11a of the housing so that the base portion 12a and the substrate portion 13a of the terminal overlap each other.
At this time, a support portion 11f located inside the folded portion 13b of the elastic member 13 is formed in the housing.
As shown in fig. 2(a) and (b), the operation portion 14c of the operation lever is located on the same side as the confirmation window 11c of the housing so as to be operable while viewing the confirmation window 11c provided in the housing.
When the operating portion 14c is rotated upward, the operating portion 14b presses the pressing portion 13c of the elastic member 13 downward, and therefore, the locking portion 13e moves in a direction away from the base portion 12a of the terminal, and is switched to the open state.
In this state, as shown in fig. 2(c), the cable 1 is inserted from the connection hole 11b into between the locking portion 13e and the base portion 12 a.
The distal end portion of the core wire 1a of the inserted cable 1 abuts against the abutting portion 15b of the indicator 15, and when the cable is further inserted, the push indicator 15 advances, and the display portion 15d is viewed from the confirmation window 11 c.
The display part 15d is viewed from the confirmation window 11c, and the operation part 14c is rotated downward.
This state is shown in fig. 3(c) and (d).
Thereby, the connection operation of the cable is completed.
