Description

[Detailed Description of the Invention] This invention relates to a socket to which electrical equipment such as a relay is connected.

Conventionally, there are two types of sockets of this kind: front-connection type and back-connection type, and it is necessary to always have these two types of sockets on hand, as well as the possibility of incorrectly selecting sockets and providing different types of sockets. Mistakes such as doing this may occur. In addition, in the back connection type, the socket terminal is directly connected to the wiring on the wiring board using solder, so solder flux may rise to the socket terminal and cause poor contact between the socket terminal and the external terminal. . Furthermore, in the case of the back connection type, the dimensions between the wiring board terminals that protrude from the back of the socket are small, so
When the socket is small, the density of the wiring pattern on the wiring board increases, making it difficult to design and making short circuits more likely to occur.

This invention is configured as a common type that has both surface connection type and back connection type functions, prevents solder flux from rising to the socket terminals, and increases the dimension between the wiring board terminals. The purpose of the present invention is to provide a socket that eliminates the following inconveniences.

Hereinafter, embodiments of this invention will be described based on the drawings. In FIG. 1, reference numeral 10 denotes a socket base made of synthetic resin, and a plurality of terminal holes 11 are formed in the center of the surface thereof penetrating downward as shown in FIG. A bifurcated socket terminal 12 is fitted from above in a manner that cannot be removed. 13
are each lead-out terminal provided on the side of each socket terminal 12, each lead-out terminal 13 is exposed on the surface side of the socket base 10, and each lead-out terminal 13 has a washer 14. Motta terminal screw 15
is screwed on. A wiring board terminal 16 is integrally formed at one end of each lead-out terminal 13.
The base 17 of this terminal 16 is press-fitted into a through hole 18 formed in the socket base 10, and the tip 19 is connected to the socket terminal 1 on the back side of the socket base 10.
It protrudes to a position that is more outward than 2. The lower end 20 of the socket terminal 12 is connected to the corresponding wiring board terminal 16 by a conductive wire 21. In FIG. 1, 22 is a base mounting screw (not shown) formed on the socket base 10.
This is the inset hole.

When the socket 23 having the above structure is attached to the wiring board 24, it is of a back-side connection type. That is, each wiring board terminal 1 protruding from the back surface of the socket base 10
6 is inserted into the terminal hole 25 of the wiring board 24, and each terminal 16 and a printed wiring (not shown) of the wiring board 24 are connected by solder.

By the way, conventionally, the wiring board terminals 16 are integrally led out directly below the socket terminals 12, and therefore the socket terminals 12 are connected to the wiring board 24.
However, in the above embodiment, the wiring board terminal 16 is formed on the lead-out terminal 13, so that during the soldering, the solder flux is directly connected to the socket terminal 12. As a result, poor contact will not occur between the socket terminal 12 and the external terminal 26 inserted therein. In addition, in the configuration of the embodiment, the dimension l between the terminals at both ends is larger than in the conventional configuration, so even if the socket 23 is small, the wiring board 2
As the density of the wiring pattern in 4 becomes smaller,
The design is easy and short-circuit accidents are prevented.

On the other hand, as shown in FIG.
3 to the control panel 27, the socket 23 is of the surface connection type, and the connection fitting 29 of the wiring 28 to the socket terminal 12 is sandwiched between the lead-out terminal 13 and the washer 14 with the terminal screw 15. Therefore, the tip portion 19 of the wiring board terminal 16 shown in FIG. 2 is cut off as an unnecessary item.
Also, at this time, the separating section 30 is connected to the control panel 2.
7, the back side of the socket base 10 is connected to the back cover 31 to prevent a short circuit between the socket terminals 12 and 12.
is blocked by.

As mentioned above, the socket 23 is a common type that has the functions of both a front connection type and a back connection type.
There is no need to make mistakes such as providing different types of sockets.

In FIGS. 4 and 3, 32 is a notch formed at the boundary 33 between both terminals 13 and 16 in order to separate the tip 19 of the wiring board terminal 16 from the lead-out terminal 13. Detachment is easy. 34 is a screw hole.

According to this invention, since one end of the lead-out terminal is used as a wiring board terminal, the dimension between the wiring board terminals can be increased, the space available for the wiring pattern is increased, the socket is small, and the wiring Even if the density of the wiring patterns on the board is high, the wiring patterns can be easily designed, and short-circuit accidents between patterns can be prevented.

Furthermore, if the wiring board terminal is used to connect the wiring pattern, it can be used for back side connection, and if the tip of the wiring board terminal is cut off and used, it can be used for front side connection. It is convenient to use because both types can be used for both the front and back connection types.

In addition, since one end of the lead-out terminal is used as a wiring board terminal, when soldering the wiring board terminal and the printed wiring of the wiring board, the solder flux will rise to the socket terminal and the external terminal inserted into it. Since it does not adhere to the contact portion with the terminal, there is no possibility of poor contact between the socket terminal and the external terminal.
