目的としている。This invention was made by focusing on such conventional problems, and includes an elastic material around at least one of the hole for extending the lead wire of the back plate that holds down the optical element and the small hole of the housing. The purpose of the present invention is to solve the above-mentioned problems by absorbing the dimensional tolerance of the optical element with this elastic body.
以下、この発明を図面に基づいて説明する。The present invention will be explained below based on the drawings.

まず構成は従来技術と異なる点を中心に説明し、従来と
同じ構成については、同一番号を付して説明を略する。First, the configuration will be explained focusing on the points that are different from the conventional technology, and the same components as the conventional technology will be given the same numbers and the description will be omitted.

ている。13 is a back plate with a cylindrical protrusion 1 on the bottom 13c.
5m and 15b are provided in a protruding manner, and further, thin cylindrical protrusions 14m and 14b are provided in a protruding manner at the tips of the protrusions 15m and 15b. 12 is a housing, and a back plate 13
protrusions 15a, 15b s and cylindrical protrusion 14m,
As will be described later, the length is increased by 14b pS.

It is made of plastic such as resin, nylon, polyethylene, or polypropylene, and is molded by injection molding. Therefore, the cylindrical protrusion aperture a.

４ｂ、突部１５ｂについても同様の寸法関係とする。Here, the size 4 of the recess 12m of the connector housing 12,
The length of the optical element is tl, and the height of the cylindrical protrusion 15m is tl.

=mu(t1+tl), 0.3≦K<1. Recess 12b, optical element 3b, cylindrical protrusion 1
4b and the protrusion 15b have the same dimensional relationship.
次に作用を説明する。Next, the effect will be explained.

ｌａｇに入ってバックプレート１３がハウジング１２か
ら簡単にはずれないようになって−る。The optical elements am and 3b are housed in the recesses 12m and 12b of the connector housing 12, respectively, and then the back plate 13 is inserted so that the leads ilk and 9b of the optical elements 3b and 4a pass through the holes 131 and 13b, respectively. ! il on the back surface of the housing 12. Of course housing 1
The central parts 12c and 12d of 2 are the large back plate 13f,
lag so that the back plate 13 is not easily removed from the housing 12.
この状態では、円筒状突出部１４ｍ、１４ｂが撓んでそ

ぞれ一致する。In this state, the cylindrical protrusions 14m and 14b are bent to a height of 4 (k=0.3 to 0.8). Therefore, the optical elements &3b are firmly pressed against the small holes 12e, 12f in the recesses 12m, 12b, and there is no backlash, and the optical axes coincide with the optical fibers 6b, respectively.
この場合、０．３≦ｋ＜１としたのは、０．３未満にな

性を示さなくなったり、弾性力が強くなり過ぎて、光素
子３に損傷を与えたりする。又、ｋ＜１としたのは、ｋ
≧１では従来のように公差によりガタを生ずるからであ
る。In this case, the reason for setting 0.3≦k<1 is that if it is less than 0.3, the deflection will be too large, and depending on the material, cracks may occur in the cylindrical protrusions 14m and 14b, so that sufficient elasticity cannot be achieved. or the elastic force becomes too strong, causing damage to the optical element 3. Also, the reason why k<1 is set is that k
This is because if ≧1, looseness will occur due to tolerances as in the conventional case.

る。The dimensions of the optical element may differ from - to later, in which case the back plate, the cylindrical central part 15 & 15 of 13.
Just change the length of b. In that case, each dimensional relationship only needs to satisfy the above formula, and in that case, the value of k is 0.3≦k<1
Of course, the optical element may be changed later if the requirements are satisfied.
尚、円筒状突出部１４ｍ、１４ｂの代りに、央部１５＆

得られる。この場合、弾性体の光素子と当接する面を光
素子の弾性体と当接する部分の形状に合せても良い。A ring-shaped sponge serving as an elastic body may be attached to the end surface of 15b. In this case, the aforementioned k can also be made smaller than 0.3. Molding the back plate is easier because there are no thin parts, but on the other hand, making the sponge separately and pasting it on requires more time and effort. Further, the above-mentioned elastic body is provided alone or together with the cylindrical protrusions 15a and 15b at the portions that contact the optical elements 3b around the small diameters 12e and 12f. In that case, the same effect as in the above embodiment can be obtained. In this case, the surface of the elastic body that comes into contact with the optical element may be matched to the shape of the portion of the optical element that comes into contact with the elastic body.

られる。As explained above, according to the present invention, the structure is such that an elastic body is provided on at least one of the housing and the pack plate that accommodates the optical element, and the optical element is elastically supported within the recess. This provides the effect that the optical element does not wobble within the housing and light can be reliably transmitted to the optical fiber.
