Description

[Detailed description of the invention] (a) Technical field of the invention The invention is characterized in that a jig for cleaning a connector that has been pre-soldered and a jig for assembling the connector to a housing guide are the same. This invention relates to a jig for cleaning and assembling connectors that can be used as a jig.

(b) Prior Art and Problems As shown in FIG. It is used by fixing.

The plate 4 and the housing guide 2 are fixed to each other by screwing the mounting holes 2B and 4A provided in the housing guide 2 and the plate 4, respectively, with set screws.
As shown in b, the circular pin 2C and the oval pin 2D fixed to the housing guide 2 are fitted into the circular through hole 1C and the oval through hole 1D provided on both sides of the header 1, respectively. It is done by being done. The housing 3 is held by inserting the protrusion 3B into the comb-shaped groove 2A of the housing guide 2, and the terminal 1A is fitted into the pinhole 3A. Then, along the groove 2A, the housing 3
By sliding, the terminal piece 1A of header 1
Connections and disconnections are performed using a terminal piece (not shown) facing the terminal. On the other hand, the terminal piece 1B opposite to the terminal piece 1A is connected to a wiring material or a pattern wiring of a printed board. Therefore, the terminal piece 1A
A plated film of a highly conductive material is formed on the terminal piece 1B to minimize contact resistance, and preliminary solder is applied to the terminal piece 1B to facilitate soldering.

Conventionally, such a connector has been manufactured as shown in FIG. FIG. 2 shows a conventional jig; a is a cleaning jig; b is a perspective view of an assembly jig.

As shown in a, a base plate 11 to which the header 1 is attached and a cover plate 12 superimposed on the surface of the base plate 11.
Using a cleaning jig formed by
The terminal piece 1B of the header 1 is held between the base plate 11 and the cover plate 12 and inserted into a cleaning tank to remove the flux caused by preliminary soldering of the terminal piece 1B of the header 1.

The base plate 11 and the cover plate 12 have through-holes 11 so that the cleaning liquid can easily flow when inserted into the cleaning tank.
B and 12B are provided, and a mounting portion 1 is provided so that they can be attached or removed by overlapping each other.
1A and 12A are provided.

Therefore, first, the header 1 is attached to the surface of the base plate 11, and the cover plate 12 is turned over to secure the attachment parts 11A and 12A. The base plate 11 with the header 1 incorporated therein and the lid 12 are inserted into a cleaning tank and cleaned.
When cleaning is completed, it is taken out from the cleaning tank. Then, the cover plate 12 is taken out, and the header 1 is taken out.

As shown in b, the header 1 after cleaning is attached to the assembly jig 1.
3. Three headers 1 are installed in the assembly jig 13.
A pedestal 13A is provided which is formed by an uneven surface in which the ridges are arranged at a predetermined interval S.

Therefore, by overlapping the housing guide 2 on the arranged header 1 and pressing it, the above-mentioned mounting hole 1
C and 1D are fitted into pins 2C and 2D, and the header 1 is assembled into the housing guide 2.

As described above, the conventional method has the disadvantage that separate jigs must be used for cleaning and assembly, and furthermore, the header 1 must be attached to each base plate 11 and each jig 13. Therefore, there was a problem in that it required a lot of man-hours.

(c) Purpose of the invention The purpose of the present invention is to eliminate the above-mentioned problems by making it possible to assemble the housing guide while the header is attached during cleaning.

(d) Structure of the invention The object of the invention is to be formed by a flat plate and a cover plate that is held opposite to the plate so as to sandwich a plurality of connectors. A corner portion of each connector is held so that the connector is placed in a predetermined position that matches the mounting of a housing guide on one side and a through hole through which cleaning liquid flows when inserted into a cleaning tank. This is achieved by a connector cleaning and assembly jig characterized by being provided with a protruding pedestal.

(e) Example of the invention The present invention will be explained in detail below with reference to FIG.
FIG. 3 is a perspective view showing an embodiment of the connector cleaning and assembly jig according to the present invention.

A pedestal 2 to which the header 1 is attached to the pedestal 21
C and 2D are provided, and the cover plates 22 are overlapped to hold the headers 1, and the headers 1 are arranged so as to obtain a predetermined interval S necessary for assembling the housing guide. It is something.

The base plate 21 and the cover plate 22 have through holes 21B and 22B to facilitate the flow of cleaning liquid during cleaning.
Attachment portions 21A and 22A are provided, respectively, which are detachable from each other. Also, pedestals 21C and 21D
A groove B is provided in the header 1 so that the header 1 is positioned. Furthermore, a mounting hole 1 is provided to indicate the mounting direction so as to avoid mistakes in the horizontal mounting direction of the header 1 during assembly.
A mark 21E indicating the shapes of C and 1D is provided.

Therefore, the header 1 is attached to the base plate 21, the cover plate 22 is fixed, and the base plate 2 is cleaned after cleaning.
By removing the cover plate 22 from the housing guide 2, the housing guide 2 can be installed immediately.

(f) Effect of the invention As explained above, this invention
Cleaning of the header 1 after preliminary soldering and assembly of the housing guide 2 are carried out using the jig formed by 2 and 2. This eliminates the need for two jigs as in the past, reducing costs, and also eliminates the need to reassemble the header 1, reducing the number of man-hours, which has great practical effects.
