Description

Board mounted connectors {Connector mounted on printed circuit board}

The present invention relates to a connector, and more particularly to a board-mounted connector having a spacer for aligning a plurality of terminals provided in the connector housing mounted on a printed circuit board.

In general, the connector is composed of a connector housing and a terminal, and is widely used in power circuits such as washing machines, refrigerators, or automobiles. The use of the connector in these electrical and electronic devices has the advantage that a plurality of parts can be assembled separately and then inserted into the final product, thereby greatly simplifying maintenance work as well as device manufacture. At this time, some of the connectors are board mounted connectors that are mounted directly on the printed circuit board.

1 is a cross-sectional perspective view showing a main portion of a board-mounted connector according to the prior art.

As shown in the figure, the appearance and skeleton of the board-mounted connector 1 are formed by the connector housing 2. The connector housing 2 is generally made of an insulating synthetic resin material, and penetrates the inside and backwards thereof to form an insertion space 2 '. A plurality of terminals 4 are inserted and fixed in the insertion space 2 '. The plurality of terminals 4 are made of a conductive metal material, one end of which is positioned inside the insertion space 2 ′, and the other end of which is protruded out of the connector housing 2 to provide a printed circuit board. It is soldered to (not shown).

The locking grooves 6 are formed at both sides of the connector housing 2 so as to be recessed. The locking grooves 6 are formed at both sides of the insertion space 2 '. The locking groove 6 is a part of the hooking jaw 14 of the hook hook 12 to be described below, and serves to couple the connector housing 2 and the spacer 10 to be described below.

At this time, the temporary assembly groove 7 is formed on both sides of the connector housing (2). The temporary assembly groove 7 is formed on both sides of the insertion space 2 ′ adjacent to the locking groove 6, similarly to the locking groove 6. The temporary assembly groove 7 is a part where the hooking jaw 14 of the hooking hook 12 is hooked, and before the hooking hook 13 is hooked to the hooking groove 6, the connector housing 2 and the spacer are mounted. Allow (10) to be assembled.

A spacer 10 is coupled to the connector housing 2. Like the connector housing 2, the spacer 10 is made of a material such as synthetic resin, and serves to align and protect the position and direction of the terminal 4.

The through hole 11 ′ is a portion through which the terminal 4 passes, and is formed to penetrate at a position corresponding to the position of the terminal 4. That is, at least a portion of the terminal 4 passes through the through hole 11 'so that the terminals 4 can be aligned in the correct position.

Hook hooks 12 are formed on both sides of the body portion 11. The hook hook 12 is formed to protrude substantially in a cantilever shape. It is formed extending from the both sides of the body portion 11 in a direction orthogonal to the longitudinal direction of the body portion (11). The hook hook 12 is a portion corresponding to the locking groove 6 of the connector housing 2, and is engaged with the locking groove 6 to couple the spacer 10 and the connector housing 2 to each other. do.

Hanging jaw 14 is formed at the tip of the hook hook 12. The hooking jaw 14 is formed to protrude toward the locking groove 6 of the connector housing (2). The hooking jaw 14 is fixed to the hooking groove 6 and serves to fasten the spacer 10 to the connector housing 2.

An insertion boss 16 is formed on a lower surface of the outer surface of the body portion 11 seated on the surface of the printed circuit board. The insertion boss 16 is formed to protrude in a direction opposite to the direction in which the hook hook 12 extends from the outer surface of the body portion 11. The insertion boss 16 is inserted into an insertion hole (not shown) formed in the printed circuit board so that the connector housing 2 is temporarily assembled on the printed circuit board.

However, the above-described conventional techniques have the following problems.

Since the hook hook 12 must be inserted between the terminal 4 and the inner surface of the connector housing 2, a space corresponding to the hook hook 12 must be further formed in the connector housing 2. That is, a space equal to the sum of the thickness of the hook hook 12 and the height of the hook protrusion 14 protruding from the hook hook 12 should be further formed in the connector housing 2, so that the connector housing There is a problem that the volume of (2) is increased.

In addition, since the engaging groove 6 is formed in the inner surface of the inner space 2 ′ of the connector housing 2, the connector housing 2 adjacent to the engaging groove 6 is relatively more than the other parts. weak. Therefore, when an external force is applied to the connector housing 2, deformation may occur and the spacer 10 may be separated from the connector housing 2.

Therefore, an object of the present invention is to solve the problems as described above, to relatively reduce the volume of the connector housing.

Another object of the present invention is to allow the spacer to be more firmly fixed to the connector housing.

According to the features of the present invention for achieving the object as described above, the present invention forms the appearance and the skeleton, the insertion space is formed therein is fixed a plurality of terminals are soldered to the printed circuit board is inserted, the insertion Connector housings having a pair of fastening protrusions spaced apart from each other at predetermined intervals on both sides of the inner surface of the space; A spacer having a through hole through which a portion of the terminal passes, through which a guide bar is formed in pairs from both sides, protruding from both ends of the guide bar, and having a fixed hook formed on the fastening protrusion; It is configured to, and the inner surface of the insertion space close to the inlet of the connector housing in which the spacer is inserted is formed to protrude a protruding protrusion is the fixed hook is hooked to the spacer is assembled.
