Abstract

The utility model relates to an improved structure of a clamping hook of a connector. A snap ring is arranged in front of the clamping hook arranged in the connector, and the snap ring is used for correspondingly fastening on a fastener arranged on the other joint. The inner side of the front end of the ring body of the snap ring is provided with a curved cambered surface to fit to the shape of the fastener; therefore, a line contact is generated, the contact surface is enlarged, and the fastening effect is better. Two clamping holes are arranged on the rear of the clamping hook. The rear end of the clamping hook is sheathed with a slide button, the inner side of the slide button is provided with a slot way which the clamping hook can be sheathed in, and two oblique plane blocks are arranged on the slot way correspondingly to the clamping holes. When the rear end of the clamping hook is sheathed in the slide button, the clamping holes can clamp the oblique plane blocks to prevent the clamping hook from disengaging from the slide button; meanwhile, the firm combination effect can be realized.

Description

The grab of connector

The utility model system is relevant for a kind of grab structure-improved of connector, mainly the grab the place ahead in being installed in connector is provided with a clasp, this clasp system is used for cooperating the fastener that is held on another joint, wherein side-line is provided with a crooked cambered surface in the ring body front end of this clasp, shape with fasteners, produce line contact, enlarge contact surface, have better button and hold effect, be provided with two clip holes in this card an ancient unit of weight rear in addition, cover is with a toggle, this toggle inboard is provided with a conduit and is inserted in for grab, and cooperates the clip hole to be provided with two inclined-plane blocks, when be inserted in the toggle grab rear end, this clip hole can clip prevent in the inclined-plane block that grab breaks away from toggle, has firm in conjunction with effect.

The utility model is a kind of card an ancient unit of weight structure-improved of connector, special at the clasp in grab the place ahead and the toggle proposition improvement at rear, the contact-making surface of clasp and fastener is more expanded, and button is held more certain firm, and makes toggle and grab mat drawing piece and inclined-plane block obtain a good fixed effect.

The spare and accessory parts kind of computer connector plug is a lot of at present, yet its main structure is nothing more than cable, cable fixing device, terminal base, shell body, structure such as grab and joint, the fixed form of wherein just blocking an ancient unit of weight and joint, each producer endeavours to research and develop voluntarily invariably, constantly release the fixture construction of various different types, wherein well-known vendor A MP releases the fixed form of column fastener 21 on a kind of grab 10 with clasp and the joint 20, as Fig. 1, this connector grab 10 shown in Figure 2 is with a strip metal lamellar body bending forming, be provided with clasp 11 on it from front to back in regular turn, tip hole 12, a shell fragment 13 and a

pressing plate position

14,21 of this column fasteners lie in a pedestal 21 and extend upward a projection 22, and in this projection front end have one the expansion position 23, these expansion position 23 end faces are provided with a word hole 24, extend a screw 25 downwards in pedestal 21 in addition, and but the mat flathead screwdriver is locked this column fastener 21 in the screw 26 of joint 20 both sides, when connector 10 combines with joint 20, the expansion position 23 of these column fastener 21 front ends will snap in the clasp 11 of grab 10, and, this clasp 11 come off by being hooked to pull because of collision or mistake, when pulling up connector 10, need depress pressing plate position 14 earlier, make clasp 11 break away from column fastener 21, again connector is pulled up from joint 20, when wherein these clasp 11 hooks are held in column fastener 21 is some ways of contact, its button power of holding only acts on the edge at this column fastener 21 front ends expansion position 23, it is not satisfactory that button is held effect, more easily break away from because of vibrate or pull by mistake, and this pressing plate position 14 is a sheet metal that exposes, when the user contacts this pressing plate position 14, there is no the insulation protection effect, cause last doubt safe in utilization;

In view of this this creator proposes solution at the above-mentioned shortcoming of commonly using structure, thereby the generation of the utility model is arranged.

The main purpose of the utility model is to provide a kind of card an ancient unit of weight structure-improved of connector, this grab the place ahead is provided with a clasp, wherein side-line is a crooked cambered surface in the ring body front end of this clasp, to cooperate the shape of column fastener, producing cambered surface contacts with the line of cambered surface, enlarge contact range, make this clasp be held in the darker position of this column fastener, have better button and hold effect and reliability, be provided with a tip hole in addition behind clasp, its rear is provided with two clip holes, this grab rear forms a crooked shell fragment, and in the crooked shell fragment front end sleeve of grab with a toggle, this press button inboard is provided with a conduit and is inserted in for grab, and cooperates this clip hole to be provided with two inclined-plane blocks, after drawing piece arrives the location, this inclined-plane block will produce reverse clip effect, prevent that grab breaks away from press button, and can provide user's one insulation and sense of touch good press button structure.

A kind of grab that connects device that provides according to the utility model, it is characterized in that, there is a grab body in system, it is that a sheet metal becomes foldable type, its front end is warpage slightly, and be provided with a clasp, and wherein this clasp front end is upwards turned up, and its inboard is provided with a crooked cambered surface, system can produce a contact-making surface above 90 ° of central angles when this bending cambered surface contacted with the column fastener of joint, the hook surface at this clasp rear is provided with a depression, is provided with a tip hole thereafter, and this rear, tip hole then is provided with two clip holes, grab in rear, clip hole then is reducing of a width, and bending forms a shell fragment position, and slightly is upturned in end downwards;

Wherein a press button is inserted in this grab rear system, and it is a plastic cement block, and the inboard is provided with a conduit, and be provided with grooved rail in these conduit both sides, can slip into for this grab rear both side edges, be provided with two inclined-plane blocks in addition in the conduit surface, its inclined-plane system turns forward, the rear then is a flat face, square lateral margin after this grab is slipped in this press button grooved rail, and when entering the location, its two clips hole promptly is sleeved on two inclined-plane blocks, the flat face of this inclined-plane block will produce the effect of a check, stop grab to break away from press button.
