Abstract

An internal-retaining type optical fiber connector of an LC twin-and-split is used for fiber-optical connection in light-conductive communication facilities and is composed of inserters and an inserter-receiver. The inserter-receiver includes a complete outer housing of the twin optical fiber connector. Two inserting holes of the inserters and a lock joint hole are provided on the outer housing. The inserters are provided two members which are inside inserters embedded with metal ducts. A recess is opened on one end wall of the inserters without embedding metal ducts. A retaining member is further arranged on the end wall. The utility model is formed after the connection of the inserters and the inserting holes, and tight retaining of the retaining member and the lock joint hole. Compared with existing technology, the utility model not only remains the feature that conventional twin inserters are capable of single segregation, but also decreases the procedure and costs. Owning to the connection of the inside inserters of the complete outer housing, uniform color and luster of appearances are ensured. Simultaneously due to the recess opened on the inside inserters, expansion and contraction can be adjusted without cracking resulting from hardness compression of the housing case.

Description

The LC duplex split inner blocking type joints of optical fibre

Technical field

The utility model relates to the components and parts in the optical communications field, especially relates to a kind of duplex joints of optical fibre.

Background technology

The present LC duplex joints of optical fibre of using, shown in accompanying drawing 1--4, the insert that is subjected to be embedded with on plug-in unit and the shell body metal catheter that has shell body that comprises butt joint, and connecting rack constitutes, though this duplex joints of optical fibre that are assembled into can be realized the connection of optical fiber preferably, can realize that also the single-piece of duplex insert is separated; But each duplex joints of optical fibre needs to be subjected to plug-in unit by two, a connecting rack, and two insert five parts assemble, and manufacturing process is many, and processing and assembling are complicated, the cost height; Because joints of optical fibre volume is little, outer shell walls is very thin, in the time of in a part is inserted another part housing, tends to the crack occur at the snapping place that is inserted into partial shell; Be embedded with metal catheter on the insert because of the band shell body simultaneously, housing is by plastic production, and metal catheter is made by metal, when under the same process condition, the termination is embedded with the color of the partial shell outer wall of metal catheter can be inconsistent with the housing color of another part, influences outward appearance.

Summary of the invention

The utility model is in order to overcome the deficiency of above-mentioned prior art, a kind of LC duplex split inner blocking type joints of optical fibre of novel structure are provided, simple to reach operation, cost is low, do not ftracture, the purpose of appearance luster unanimity keeps original single-piece separation characteristic of realizing the duplex insert simultaneously, to satisfy the user's request that this requirement is arranged.

For achieving the above object, the technical solution of the utility model is such: a kind of LC duplex split inner blocking type joints of optical fibre, comprise and be subjected to plug-in unit and insert, the said shell body that is subjected to plug-in unit to comprise the whole duplex joints of optical fibre, housing is provided with 2 patchholes arranged side by side of insert, and the housing outer wall is provided with the snapping hole; Said insert is the plug-in part that is embedded with metal catheter, does not have groove on engaged column conduit one end wall at insert and lacks, in order to elastic telescopic; On this end wall, also be provided with fastener, 2 inserts are connected with patchhole respectively, and with fastener and the fastening of snapping hole.

Owing to adopted technique scheme, a kind of LC duplex split inner blocking type joints of optical fibre of the present utility model become one the shell and the connecting rack merging of the former duplex joints of optical fibre, are embedded with on the insert of metal catheter and are not with shell body; Make the former duplex joints of optical fibre need to form by five parts, and the connecting mode that adopts shell body to connect, changing to become only needs three parts, and still keeps original characteristics that realize that duplex insert single-piece is separated, and has reduced operation, has reduced cost; The plug-in part of employing in monolithic case connects, and guaranteed the appearance luster unanimity; Simultaneously scarce because of groove is set on plug-in part, can adapt to flexible, can rigid extruding shell and cause cracking.

Embodiment

By Fig. 1-shown in Figure 4, be the LC duplex joints of optical fibre of background technology, comprise the insert 4 that is subjected to be embedded with on plug-in unit 1 and the shell body metal catheter 5 that has shell body, and connecting rack 3 constitutes, wherein insert 4 passes connecting rack 3, connect with patchhole 6, and form by fastener 7 and snapping hole 2 snappings; Each duplex joints of optical fibre needs to be subjected to plug-in unit by two, a connecting rack, and two insert five parts assemble, and need five processes during manufacturing, and processing and assembling are complicated, the cost height; Because joints of optical fibre volume is little, outer shell walls is very thin, in the time of in a part is inserted another part housing, tends to the crack occur at the snapping place that is inserted into partial shell; Be embedded with metal catheter on the insert because of the band shell body simultaneously, housing is by plastic production, and metal catheter is made by metal, when under the same process condition, the termination is embedded with the color of the partial shell outer wall of metal catheter can be inconsistent with the housing color of another part, influences outward appearance.

Shown in Fig. 5-7, a kind of LC duplex split inner blocking type joints of optical fibre of the present utility model, comprise and be subjected to plug-in unit and insert, the said shell body 8 that is subjected to plug-in unit to comprise the whole duplex joints of optical fibre, shell body 8 is provided with two patchholes arranged side by side 9 of insert, and the housing outer wall is provided with snapping hole 10; Said insert is the plug-in part that is embedded with metal catheter 11, does not have groove on engaged column conduit one end wall at insert and lacks 13, in order to elastic telescopic; On this end wall, also be provided with fastener 12, two inserts connected with patchhole 9 respectively, and with fastener 12 with 10 fastenings of snapping hole.
