GB2189658A - Connector with solder cover - Google Patents

Abstract

A connector (1) includes a temporary cover (6, Fig. 3) over contact blades (5) so as to prevent solder being deposited on the blades when pins (4) of the connector are soldered to a board (8). The cover (6) is joined to the body (2) of the connector by frangible bridges (7) which are broken to sever the cover (6) from the body (2) when the connector mates with a counterpart (Fig. 2). <IMAGE>

Description

SPECIFICATION Connector BACKGROUND OF THE INVENTION The present invention relates to a connector for electric connection, more particularly to a connector to be efficiently connected with audio equipments such as amplifiers, tuners, receivers or CD players or displaying equipments such as VTRs or televisions at right angles.

Conventional connectors, as shown in a utility model examined publication of Japan NO.

55-11085 are so constructed that fluxes of a solder are adhered, when soldering terminals of a male connector 3 to a printed board, because conductors 4 and 14 of the male connector 3 are disclosed.

The prior art mentioned above does not consider the point that fluxes of a solder are flown off and adhered to conductors of a male connector when soldering terminals of a male connector to printed boards, and has a problem that the electric connection with a female connector is imperfect as a result.

SUMMARY OF THE INVENTION The object of the invention is to provide perfect connections of electricity by mounting a cover of synthetic resins covering conductors of a male connector previously to prevent conductors from adhering even if fluxes of a solder flies off.

The above and further objects and novel features of the invention will more fully appear from the following detailed description when the same is read in connection with the accompanying drawing. It is to be expressly understood, however, that the drawing is for purpose of illustration only and is not intended as a definition of the limits of the invention.

DRA WINGS Figure 1(a) is a stereoscopic view showing a male connector according to an embodiment of the invention; Figure 1(bJ is a plan view showing the male connector in Fig. 1(a); Figure 1(c) is a side view showing the male connector in Fig. 1(a); Figure 2 is a side view showing the connecting a male connector with a female con nector perpendicularly; and Figure 3 is a side view showing the soldering a male connector.

DESCRIPTION OF PREFERRED EMBODIMENTS Explanation, hereinafter, is made to an embodiment of the invention with reference to Fig. 1, Fig. 2 and Fig. 3.

In Fig. 1, the numeral 1 indicates a male connector which is made of synthetic resins and buries and fixes conductors 3 by a holder 2 insulating the spaces between poles.

The conductors 3 consist of terminals to be soldered to printed boards and contact arms 5 to be inserted into and connected with conductors of a female connector.

On the other hand, one end of the contact arms 5 is opened and the other end is covered with a cover of a pouch type not opened, in which the cover 6 and the holder 2 made of the same synthetic resins as is used for the cover is connected by connecting bars which are fine and breakable.

Fig. 3 illustrates the state that the terminals 4 of the male connector 1 are soldered to a printed board by soldering equipments, together with other electric parts after inserting the male connector 1 shown in Fig. 1 into the printed board and then opposing a cover 6 at the place that one end of the printed board 8 is opened, in which the numeral 9 indicates a solder.

In this state, when pressing the cover 6 in a direction of P, the extremely fine connecting bars 7 are broken and separated from the holder 2 and dropped downwards, as a result, the contact arms 5 are disclosed.

Fig. 2 shows the state that connecting is performed perpendicularly by a connector of the device.

A female connector 10 is inserted into a printed board 12 opposing the printed board 8 perpendicularly and the terminals 4 are fixed by the solder 9.

On the other hand, there are female contact arms 11 on the extended line of the end of the terminals into which male contact arms 5 of the male connector 1 are inserted to contact together and to conduct.

According to the invention, adhesion of fluxes from Q direction, when soldering, can be prevented because of covering one end of the male contact arms with a cover.

1. A connector consisting of a holder and conductors characterized by covering contact arms of ends of said conductors with a cover and connecting said holder to said cover with connecting bars.

2. A connector substantially as hereinbefore described with reference to and as shown in the accompanying drawings.

3. Any novel integer or step or combinations of integers or steps, hereinbefore described, irrespective of whether the particular claim is within the scope of, or related to the same or a different invention from that of, the preceding claims.
