Abstract

PROBLEM TO BE SOLVED: To provide a dust protective wall structure of a pin header-type connector, for smoothly and sequentially feeding one by one many pin header-type connectors housed in a stick carrier to an automatic assembling machine. SOLUTION: An insulator 2 of a pin header-type connector 1 has a rectangular parallelepiped shape, and a flange-shaped dust protective wall 2A is formed around the center of four upper, lower, right and left front surfaces. In a stick carrier, one protrusion 2B is formed on the right side of the back surface of the protective wall, in order to prevent respective dust protective walls of two mutually adjacent pin header-type connectors from being overlapped. The number of the protrusions can be changed in plural fashions. The forming places of the protrusions on the dust protective wall can be changed to the right side of the back surface or to both right and left sides of the back surface.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust-proof wall structure of a pin header type connector. More specifically, a plurality of pin header type connectors housed in a stick carrier are smoothly supplied to an automatic assembling machine one by one. The present invention relates to a dust-proof wall structure for a pin header type connector.

[0002]

2. Description of the Related Art First, a conventional pin header type connector and a stick carrier will be described with reference to FIG.

The synthetic resin insulator 2 of the pin header type connector 1 has a rectangular parallelepiped shape, and a flange-shaped dustproof wall 2A is integrally formed around the center of the four upper, lower, left and right surfaces. The pin header type connector 1 is inserted into a unit (not shown), but the dustproof wall 2A prevents external dust from entering the unit from the clearance between the pin header type connector 1 and the unit.
Note that a large number of contacts 3 bent at right angles are mounted on the back surface of the insulator 2.

[0004] The stick carrier 4 is in the shape of a square tube and is made of transparent vinyl chloride. Two straight protrusions 4A and 4B are formed in parallel from one end to the other end of the inner lower surface of the stick carrier 4 by press working, and a guide groove 4C is formed between the two protrusions 4A and 4B. . A protrusion 4D is formed on the inner upper surface of the stick carrier 4 symmetrically to the protrusion 4A, and a straight protrusion 4E is formed from one end to the other end of the inner back surface of the stick carrier 4.

When the pin header type connector 1 is stored in the stick carrier 4, it is positioned as follows. That is, the lower portion of the dustproof wall 2A of the pin header type connector 1 is inserted into the guide groove 4C of the stick carrier 4, the upper front surface of the dustproof wall 2A contacts the rear surface of the protrusion 4D, and the rear surface of the insulator 2 is the front surface of the protrusion 4E. Abut.

Next, the disadvantages of the prior art will be described with reference to FIG. FIG. 3A shows a normal state in which the dustproof walls 2A of many pin header type connectors 1 are inserted adjacent to each other and parallel to the guide grooves 4C of the stick carrier 4. FIG. 3B shows an abnormal state in which the dustproof walls 2A overlap and are inserted obliquely into the guide grooves 4C.

[0007] A large number of pin header type connectors 1 are housed in a stick carrier 4 inclined with respect to the horizontal direction to facilitate supply to an automatic assembling machine. In order for a large number of pin header type connectors 1 to be sequentially supplied one by one to the automatic assembling machine and inserted into the unit, it is necessary that each pin header type connector 1 slides smoothly in the stick carrier 4. Therefore, a considerable clearance must be provided between each pin header type connector 1 and the stick carrier 4. At this time, in the conventional technique, the dustproof walls 2A of the many pin header type connectors 1 overlap with each other as shown in FIG. 3B, and the many pin header type connectors 1 are stuck in the stick carrier 4. Often occurs.

[0008]

SUMMARY OF THE INVENTION Therefore, the present invention improves on the disadvantages of the prior art, and a number of pin header type connectors housed in a stick carrier are smoothly supplied to an automatic assembler one by one. Thus, the structure of the dust-proof wall of the pin header type connector is modified.

[0009]

The present invention employs the following means to solve the above-mentioned problems.

[0010] 1. A dust-proof wall structure of a pin header type connector in which at least one protrusion is formed on one of a back surface and a front surface of a flange-shaped dust-proof wall formed around the center of four surfaces of upper, lower, left and right or two surfaces of left and right in a rectangular parallelepiped insulator.

2. 2. The dustproof wall structure of the pin header type connector according to claim 1, wherein the protrusion is formed on the other side of the rear surface or the front surface.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A dustproof wall structure of a pin header type connector according to an embodiment of the present invention will be described with reference to FIG.

The insulator 2 made of synthetic resin of the pin header type connector 1 has a rectangular parallelepiped shape, and a flange-shaped dustproof wall 2A is integrally formed around the center of the four upper, lower, left and right surfaces. On the back surface of the insulator 2, a number of contacts 3 bent at right angles are mounted.

In this embodiment, as shown in FIG. 1, one dustproof wall 2A is provided on the right side of the rear surface of the dustproof wall 2A to prevent the dustproof walls 2A of two adjacent pin header type connectors 1 from overlapping. The individual protrusions 2B are integrally formed. Projection 2B
Can be changed in design to a plurality. Further, the projection 2B is formed on the dustproof wall 2A on the left side of the rear surface,
Alternatively, the design can be changed on both the left and right sides of the back surface.

Further, the integral molding portion of the flange-shaped dustproof wall 2A in the insulator 2 can be changed in design to two right and left surfaces of a rectangular parallelepiped. Further, the design can be changed so that the projection 2B is formed integrally with the front surface of the dustproof wall 2A.

[0016]

As is apparent from the above description, the present invention has the following advantages.

1. In any of the pin header type connectors, there is no inconvenience of clogging in the stick carrier, so that the connectors are sequentially supplied one by one to the automatic assembling machine smoothly.

2. Since the projections can be integrally formed on the dust-proof wall made of a synthetic resin or the like, the manufacture is simple.
