Abstract

PURPOSE: To improve the economical performance and workability when assembling a wire in a connector by inserting the wire into a rubber bush without using a jig. CONSTITUTION: When an actuator member 31 is inserted into a cavity 12, contactors 2 are inserted into counterpart hole parts 34 and projected parts 33 are engaged with groove parts 32 and move in wire holding parts 20 (the bottom parts of the cavities 11, 12) in up and down directions and hole parts 21 of the holding part 20 are connected and held in the part where contactors are gathered. A rubber bush 40 has holes to insert wire 1 into and comprises recessed parts 41A formed on one side and a through holes 41B penetrating from the bottom part of the recessed part 41A to the other face. The contactors 2 which terminate wire 1 are inserted into the recessed parts 41A and penetrate the through holes 41B while widening the holes 41B. Since the aperture shapes of the recessed parts 41A are conformed to the cross-section shapes of the contactors 2, the directions of the contactors 2 are determined. Respective wires are sealed by the through holes of the hole parts. The bush 40 is fixed in the cavity 11 of a housing 10. Consequently, the workability is improved.

Description

Detailed Description of the Invention

TECHNICAL FIELD This application relates to a waterproof type connector. [Prior Art] Conventionally, in this type of connector, wire rods terminated by a contactor were passed through rubber bushes one by one in advance by using a dedicated jig and housed in a cavity of a housing in a sealed state. Therefore, it takes time and effort to assemble the wire into the connector, and it has been required to seal the wire in the connector by a simpler means. In the past, considering workability when penetrating a wire into a rubber bush, most of them are round pins (no directionality).
For example, connection with a tab-shaped contactor provided on a printed circuit board was impossible.

[Object of the Invention] The present invention has been invented in order to eliminate such a conventional inconvenience, and an object thereof is to pierce a rubber bush with a wire rod without using a jig and to assemble the wire rod into a connector. To improve the economical efficiency and workability of the device, and to provide a connector that can be connected to a tab-shaped contact provided on a printed circuit board.

[Description of Embodiments] A connector assembly according to the present application will be described below in detail based on illustrated embodiments. FIG. 1 shows a first embodiment of the present invention. The one shown in the drawing is a female connector, and in a practical use mode, for example, as shown in FIG. 2, the connector is connected to a tab 61 of a male connector 60 provided on the printed circuit board 50. Further, since the difference between male and female as a connector depends on the shape of the contactor, it is not essential and the connector assembly of the present application can be applied to both. In FIG. 1, 1 is a wire rod, which is terminated by a contactor 2. Further, the contactor is typically a cylindrical type having a rectangular cross section, but the present invention is not limited to this as described above.

Reference numeral 10 denotes a housing, which has a cavity 11 capable of accommodating a rubber bush 40 described later and a cavity 12 also accommodating an actuator member 31 described later. The latter cavity 12 is the bottom of the former cavity 11,
It is formed so as to project from the opposite side of the cavity 11 into the cavity 11. A wire rod holding portion 20 having a hole 21 for inserting the wire rod is provided at the bottom of the cavity 11. As will be described later in detail, the holding portion can be moved in the vertical direction (in the illustrated embodiment) by the actuator member 31. Needless to say, the shape of the hole portion 21 of the wire rod holding portion is not limited to that of the illustrated embodiment. Reference numeral 31 denotes an actuator member, which is a hole portion 3 for receiving the contact penetrating the rubber bush and the wire rod holding portion.
4 and a protrusion 3 provided at the bottom of the cavity 12 of the housing 10.
And an engaging groove 32 corresponding to No. 3.

When this actuator member is inserted into the cavity 12, each contact is inserted into the corresponding hole portion 34 of the actuator member, and the projection 33 engages with the groove portion 32, so that the wire rod holding portion 20 (cavities 11 and 12). 2) in the vertical direction (in the case of the illustrated embodiment), and the hole portion 21 of the wire rod holding portion is engaged and held by the constricted portion of the contactor 2 as shown in FIG. Four
Reference numeral 0 denotes a rubber bush, which has a hole for penetrating the wire. This hole is composed of a recess 41A provided on one surface of the rubber bush and a through hole 41B penetrating from the bottom of the recess to the other surface of the rubber bush. An opening having a shape matching the cross section of the contact is provided in the recess.

The contactor terminating the wire rod is first inserted into the recess of the rubber bush, and then penetrates the through hole while expanding the through hole. At this time, the opening shape of the recess corresponds to the cross section of the contactor. Therefore, the direction of the contact is determined. Further, each wire is sealed by the through hole of the hole. The rubber bush is fixed in the cavity 11 of the housing, and the means for this is, for example, a protrusion on the outer wall of the rubber bush.
Further, a fitting groove for fitting with the protrusion may be provided in the housing.

The structure of the connector assembly according to the present application has been described above in detail, but the following unique effects can be obtained from the structure. That is, in the connector according to the present application, the end portion of the wire can be inserted into the rubber bush without using any special jig and tool, and at that time, the shape of the non-circular end portion and the shape of the recessed portion of the rubber bush must be matched. Thus, the wire rod that keeps the insertion direction constant and that penetrates the rubber bush is sufficiently sealed by the through hole that communicates with the recessed portion.

Further, when the holding plate according to the present invention is used in the housing, the terminal end portion of the wire rod is inserted into the hole portion of the holding plate and then the plate is slid to collectively terminate the plate. Since the parts can be engaged and held, the efficiency of the assembly work is significantly improved. Further, by making the contactor of the present invention into a tubular shape having a rectangular cross section, it can be connected to a flat tab terminal (contactor) provided on a printed circuit board, and its application is wide.

In addition, the type that uses a rubber bush for waterproofing can also insert the end portion of the wire into the rubber bush and assemble it into a connector without using special jigs and tools. By matching the shape of the portion and the shape of the recessed portion of the rubber bush, the insertion direction is kept constant, and the wire rod that penetrates the rubber bush is sufficiently sealed by the through hole communicating with the recessed portion.

Further, since the connector assembly and the connector according to the present application are provided with the wire rod holding portion which can be biased in the housing, the wire rod holding portion is inserted into the hole of the wire rod holding portion and then held. By biasing the portions, the end portions can be engaged and held by the holding portion collectively, so that the efficiency of the assembly work is significantly improved.
