Liquid crystal polymer composition for connectors and connector
First Claim
1. A liquid crystal polymer composition for connector product, having a ratio (L/t) of the length (L) of the product to the average thickness (t) thereof of at least 100 and a ratio (L/h) of the length (L) of the product to the height (h) thereof of at least 10, which is obtained by blending 100 parts by weight of a liquid crystal polymer (A) with 10 to 70 parts by weight of a fibrous filler (B) having an average fiber diameter of 0.5 to 20 μ
- m and an average aspect ratio of not exceeding 10, and 5 to 100 parts by weight of a particulate filler (C) having an average particle diameter of 0.1 to 50 μ
m, the total amount of the fillers not exceeding 150 parts by weight.

Abstract
To provide a material improved in dimensional accuracy and reduced in the extent of deformation caused by warpage without suffering from a serious reduction in mechanical properties such as flexural properties, and suitable for connectors which have a ratio (L/t) of the length (L) of the product to the average thickness (t) thereof of at least 100 and a ratio (L/h) of the length (L) of the product to the height (h) thereof of at least 10. A liquid crystal polymer composition for connectors, having a ratio (L/t) of the length (L) of the product to the average thickness (t) thereof of at least 100 and a ratio (L/h) of the length (L) of the product to the height (h) thereof of not exceeding 10, which is obtained by blending 100 parts by weight of a liquid crystal polymer (A) with 5 to 100 parts by weight of a fibrous filler (B) having an average fiber diameter of 0.5 to 20 μm and an average aspect ratio of 10 or less and 5 to 100 parts by weight of a particulate filler (C) having an average particle diameter of 0.1 to 50 μm, the total amount of the fillers not exceeding 150 parts by weight.
