Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an assembly connector for a wire terminated with a contact.

[Prior art]

Advances in electronics technology have been rapid in recent years, and the fields of its application are expanding significantly as electronic components become smaller and more dense. Therefore, printed circuit boards and the like assembled with a large number of these electronic components are also widely used in various forms.

Furthermore, various types of connectors for connecting these printed circuit boards or the like or for connecting printed circuit boards and other electronic components have been developed depending on the purpose of use.

However, as the degree of integration of electronic components increases, the number of wires to be connected also increases, and connectors also need to be small but connect a large number of pins and a large number of contacts. Moreover, until now there have been few practical connectors of the type that meet the above requirements and can be supported and connected to, for example, tab-shaped terminals on printed circuit boards.

The present invention was developed in view of these circumstances, and an object of the present invention is to provide a connector that can assemble a large number of contacts with little effort.

[Explanation of Examples]

The connector according to the present application will be explained in detail below based on illustrated embodiments.

FIG. 1 shows a first embodiment of the invention. The illustrated connector is a female connector, and in actual use, it is connected to a tab 41 of a male connector 40 provided on a printed circuit board 50, as shown in FIG. 6, for example. However, the connector of the present application is not limited to this, and it is also possible to connect as a pair of female and male connectors, for example. Further, since it depends on the shape of the male and female contacts as a connector, it is not essential, and the connector of the present application can be applied to either.

In FIG. 1, 1 is a wire rod, each of which terminates at a contact 2. In FIG. Additionally, the contact typically has a cylindrical shape with a rectangular cross section, but as described above, the present invention is not limited to this.

Reference numeral 30 denotes a housing, which has a cavity portion that also accommodates a holding blend, which will be described later, and a hole portion 36 that receives the contactor that has passed through the holding plate. Note that the manner in which the contact is received in the hole is as shown in FIGS. 2, 6, and arrow diagrams, which will be described later.

A holding plate 20 has a hole 21 through which the terminal end of the wire is inserted.

The hole of this holding plate is formed by integrating a part through which the contact is inserted and a part which engages the terminal end of the wire, and more specifically, the hole is large enough to allow the contact to be inserted therethrough. It consists of a tenth through hole 21A having an opening and a second through hole 21B having an opening smaller than the opening of the first through hole.

(1) In the illustrated embodiment in which the contacts of each wire are inserted through the tenth through hole, the contacts are inserted through the holding plate and then housed in the holes 36 that communicate with the outside of the housing from the bottom of the cavity.) Then, when the holding plate is displaced (slided), each wire rod is connected to the contactor and the wire rod (
(constricted) is engaged with the second through hole (see FIGS. 2 to 5).

Another embodiment of the holding plate is shown in FIG.

The illustrated plate is disc-shaped (and therefore the housing housing it also has a cavity with a circular opening);
First, each wire contact 2' is inserted into the hole 11' of the plate. Since the contact has a flange 2'A, the hole needs to have a diameter sufficient to allow the flange to pass through.

After each wire rod is inserted into the through hole of the illustrated plate, by rotating the plate, each wire rod comes into a resting state with the hole portion of the plate.

In the embodiment of FIG. 1, the retaining plate is provided with, for example, a spring member 22 on one side edge of the plate so that it can be locked within the housing. The spring member locks the retaining plate within the cavity of the housing by pressing the retaining plate against the inner wall on the side opposite the spring member.

As shown in FIG. 8, this locking means can also be realized by providing a latch 23 on the side of the holding plate and correspondingly providing a notch in the inner wall of the housing.

In order to move (slide) the holding plate temporarily locked by the locking means, a tool 35f for moving the holding plate is inserted into the through hole 34 provided in the housing.
The tool is inserted and engaged with a notch 24 in the side edge of the retaining plate to displace the plate (see FIG. 2).

Note that the holding plate may be displaced by other means such as, for example, making the circumferential surface of the contactor a cam surface and displacing the holding plate as the contactor is inserted into the through hole of the holding plate. is possible.

To indicate the displacement of the holding plate, for example, a pole 25 projecting from the holding plate is engaged with an indicator hole 35 drilled in the housing. The indicator hole consists of a through hole portion 35A and a blind hole portion 35B, and as the holding plate is displaced, the pole moves to the blind hole portion and is no longer visible from the outside, allowing the movement of the plate to be confirmed from the outside.

In the figure, 33 is a means for displacing the holding plate only in a predetermined direction within the housing, specifically, movement in a direction crossing the direction along the surface of the holding plate. Consists of a stopper that prohibits

2 and 3 show that in the first embodiment of the invention shown in FIG. 1, the contact is engaged with the holding plate and accommodated in the contact holding hole 36 in the housing. Show the steps.

First, as shown in FIG.
is inserted, the tool is engaged with the notch 24 in the side edge of the retaining plate, and the retaining plate is slid.

At this time, since the first through hole 21A' of the holding plate and the hole 36 of the housing are aligned, the contact is housed and held in the latter hole through the former through hole.

When the tool 35 is removed, the holding plate is restored to its original position by the action of the spring member of the holding plate as shown in FIG.
is engaged with the second through hole of the holding plate to hold the contact housed in the housing.

FIG. 6 shows a longitudinal sectional view of the connector and assembly according to the present invention connected to a male connector provided on a printed circuit board.

In the illustration, 50 is a printed circuit board, 41 is a tab-shaped terminal (contactor), 40 is a male connector housing, and 37
is a waterproof O-ring.

The connector of the present invention is used here as a female connector.

The configuration of the connector according to the present application has been explained in detail above,
The following unique effects can be achieved from this configuration.

That is, the connector according to the present application has, in the housing,
When using the holding plate according to the present invention, after inserting the terminal end of the wire into the hole of the holding plate, the terminal end is engaged and held by the plate at once by sliding the plate. This greatly improves the efficiency of assembly work.

Furthermore, since the contact of the present invention is shaped like a cylinder with a rectangular cross section, it can be used for a wide range of applications, such as being able to connect to a flat tab terminal (contact) provided on a printed circuit board.
