[Detailed description of the invention]

[0001]

The present invention relates to , for example, a crystal display element.
Useful for electrical connection with circuit boards etc.
Connector with support material on the side of connector member
(Hereinafter referred to as a connector with support. ) In particular, it relates to a connector with support that makes it easier to feed in the parts feeder than conventional connectors with support, shortens the feed cycle time, and enables stable automatic assembly. is there.

[0002]

2. Description of the Related Art Conventionally, as a connector , a rod-shaped body such as a conductive silicone rubber sheet and an insulating silicone rubber sheet which are alternately and parallelly multiplexed is generally used. for the convenience of handling of the connector, Gore by JIS K 6301 a type on the outside
And a support layer made of insulating silicone rubber having a rubber hardness (hereinafter simply referred to as rubber hardness) of 35 ° H or less.
Used. However, as the rubber hardness of the support material decreases, the crosslink density of the rubber decreases and the raw material contains
Since the reduced amount of filler added et al is, with Nebari and sticky after curing, stickiness occurs that stick Matowari, also ability to quickly move the like substrate surface, so-called sliding properties decrease.

[0003]

Thus [devised SUMMARY], in the conventional <br/> support with connector, when the automatic built like a liquid crystal module using the parts feeder, with support connectors or supports with connector parts feeder inner surface The feed cycle time increases, the connectors with supports cannot be separated one by one, and the feed stops, and the equipment of the line automatic assembly equipment is fully utilized. However, there is a disadvantage that the working efficiency is reduced and the assembly is also defective.

[0005]

[Function] In the connector with support described above , the coat layer is
Excellent electrical, environmental resistance, and mechanical strength
Or, since the rubber hardness <br/> higher than rubber used in the support material, the crosslinking density is high, the stickiness less, better be slippery as compared to the addition amount increasing Runode, support material of the filler Therefore , this is a liquid crystal module with a parts feeder.
When automatic incorporation into Yuru gets rid be supported with connectors <br/> or support connector with a parts feeder is attached, reduced feed cycle time is performed, the line automatic embedded device can be sufficiently utilized. This is described in more detail below.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The connector with support of the present invention
The connector member used is a conventionally known connector
Members, for example, conductive members and insulating members alternately, and
A so-called S-type connector member that is arranged in a large number in parallel
And so on. For conduction of connector members
The support material provided on the side that is not involved has a degree of polymerization of 2,0
Liquid silicone bottle with 00 ~ 3,000, viscosity 500 ~ 100,000cS
The rubber hardness after curing is 35 ° H
The following are preferred.

[0007] Further co <br/> over coat layer provided on the outer surface of the support material, electrical characteristics, the environment resistance, degree of polymerization
50,000-10,000 cs and viscosity of 1,000,000-9,000,000 cS
A cured product of silicone rubber is used.
Rubber is natural rubber, butyl rubber, neoprene rubber,
Intermolecular attraction is smaller than other organic rubbers and synthetic rubbers,
Since sufficient mechanical strength cannot be obtained by itself,
Addition is required. On the other hand, the stickiness and slipperiness described above
The rubber hardness of the cured coat layer should be
At least 40
While ° Ru needs to be H, this is <br/> in that beyond the 80 ° H has deteriorated workability of the raw material, than difficulty occurs in workability, the rubber hardness 40 to 80 ° Selected from the range of H
Must be a value.

[0008] In addition to increasing the mechanical strength of the coating layer, rubber
To achieve the above hardness, the silicone rubber
The amount of filler added must be 30 to 60% by weight.
To silicone rubber better rather it is that constitute the support material
It is better to use more than
Reinforcing filler and non-reinforcing to increase weight and increase hardness
It is preferable to use a filler in combination. In particular, in this case
When the filler amount is 45-55% by weight, the rubber hardness is 70-80 ° H.
And high rubber, and a coat layer with favorable characteristics is obtained.
Can be In addition, as the above-mentioned reinforcing filler, dry type (fume
Formula) Silica and wet silica are used as non-reinforcing fillers.
Diatomaceous earth, quartz powder, calcium carbonate, novacular
(Siliceous sandstone) and the like.

[0009] The thickness of the coat layer, the coat layer reduces the stickiness of the support with the connector state, and are not improving slip properties, this is the not be obtained support material original rubber hardness thick, with support Since the load when the connector is compressed increases, it is preferable that the thickness be 20 μm to 50 μm in consideration of the ease of forming the coat layer.

The coating layer may be bonded and integrated with the support material. However, if it is desired to reduce the compressive force when mounting the connector with the support as much as possible while improving the slipperiness in the parts feeder , the incorporation is preferable. Afterwards, the coating layer may be removed and , if necessary, bonded to the coating layer with a silicone-based pressure-sensitive adhesive so that it can be re-adhered.

Next, a method for manufacturing the connector with support of the present invention will be described with reference to the accompanying drawings. 1) Formation Figure 1 of the coating layer is an explanatory view of a coating layer forming step, in this step the carrier for elongated film (hereinafter carrier film such as polyester) 1 is traveling, the reinforcing filler on the Of 5,000 containing non-reinforcing filler and 30-60% by weight
