Abstract

The utility model relates to a fixture, which comprises a metal shell of a connector and a locating element on the metal shell. Wherein, the first fastening and second fastening piece are respectively arranged on the metal shell and the locating part of the locating element. Thus, the clamping force of the first and second fastening piece is utilized to fix the locating part on the metal shell, thus forming a combined fixture with variable fixing parts for the connector.

Description

The fixture construction improvement of connector

Technical field

The fixture construction improvement of the relevant connector of the utility model aims to provide a kind of fixing structure of composite type that can allow connector conversion fixed position.

Background technology

Electric devices such as general consumption electronic products, information storage capacity and data read in order to increase, the convenience of unloading, how can be at the configuration memory card connector of its device own, allow electric device can see through the memory card connector running that is connected with the memory card of set specification, or, allow electric device can see through the running that is connected with other electric device of signal line connector at the signal line connector that device itself configuration is planted and connect for the related signal transmission line.

Above-mentioned memory card connector and transmission line connector (following general designation connector), mostly be directly to be built on the printed circuit board (PCB) of electric device, and as shown in Figure 1, by the limit configuration of a metal shell 10 as associated fitting (memory card 20 as shown in the figure), and as the structure of electromagnetic wave shielding, this metal shell 10 generally is to utilize the mode that welding is sticked together to be fixed on the printed circuit board (PCB) 30, in the hope of reach with printed circuit board (PCB) 30 in conjunction with and the double effect that connects mutually with ground path.

The fixture construction of commonly using connector as shown in Figures 1 and 2, be at the avris integrated punching moulding of its metal shell 10 fixed part 11 in order to fit with printed circuit board (PCB) 30, involutory by fixed part 11 with the fixing point 31 of printed circuit board (PCB) 30, make the metal shell 10 of connector be able to solid welding accurately in predetermined fixed position; Again, in the general development process of electric device before volume production, or change money after the volume production, can do change slightly to the circuit layout of inside unavoidably, that is cooperate slightly possibly in order to the fixing point position of installing connector and to adjust; Yet, mostly the fixture construction of commonly using is and the machine-shaping of metal shell one, can't cooperate the opposite position of adjusting fixed part at all, so not only can cause the obstruction of designing and developing, more likely must change the whole metal shell or the design of whole connector, cause unnecessary cost expenditure, serious in even the production capacity that influences commodity.

The utility model content

The purpose of this utility model is to provide a kind of fixing structure of composite type that can allow connector conversion fixed position.

In view of this, the utility model is promptly providing a kind of composite type that can allow connector conversion fixed position fixing structure, and this composite type fixedly structure is metal shell by connector basically, and the keeper that is installed on the metal shell constitutes; Wherein, be provided with first, second clamping part of mutual correspondence respectively at the specified location of metal shell and keeper, utilize the fastening effect of first, second clamping part that keeper is fixed on the metal shell, and constitute a kind of fixing structure of composite type that can allow connector conversion fixed position.

[figure number explanation]

10 metal shells, 40 keepers

11 fixed parts, 41 second clamping parts

12 first clamping parts, 411 button holes

121 collude sheet 42 fixed parts

20 memory cards, 43 risers

30 printed circuit board (PCB)s, 431 salient points

Embodiment

The fixture construction improvement of the utility model connector, the basic structure of its fixture construction is formed as shown in Figures 3 and 4, and by the metal shell 10 of connector, and the keeper 40 that is installed on the metal shell 10 constitutes; Wherein, the specified location of metal shell 10 and keeper 40 is provided with first,

second clamping part

12,41 of mutual correspondence, and whole fixture construction promptly utilizes the fastening effect of first, second clamping

part

12,41 that keeper 40 is fixed on the metal shell 10.

Please cooperate simultaneously with reference to Fig. 5 and shown in Figure 6, in the specific implementation, keeper 40 is provided with a fixed part 42 that fits with printed circuit board (PCB) 30, and riser 43 that fits with metal shell 10 sidewalls, and be provided with the buckle ear 44 that overlaps mutually with metal shell 10 at the position up and down of riser 43, its second clamping part 41 promptly is made of the button hole 411 that is located on the buckle ear 44; As for, 12 of first clamping parts are made of the corresponding sheet 121 that colludes that is located on the metal shell 10, and first clamping part 12 and second clamping part 41 promptly see through and collude the mode that sheet 121 snaps in button hole 411 and form firm fastening effect.

With this structure, obtain a kind of knockdown fixture construction, can be after metal shell 10 and keeper 40 machine-shapings out of the ordinary, be combined into connector again, in order to stick together with printed circuit board (PCB) utilization welding or the fixture construction of other fixed form (for example with the screw locking or with different modes such as latch are fixing); Especially, when the fixing point position of printed circuit board (PCB) changes to some extent, only need to cooperate the fixed part position that changes keeper, also being about to fixed position puts the keeper that meets with the fixing point position and is assembled on the metal shell and uses, promptly can adjust the fixed position that changes of connector, do not need to change the original design of metal shell, effectively reduce the expenditure of material cost and related development cost.

Moreover, as Fig. 5 and shown in Figure 6, keeper 40 in the utility model further is provided with salient point 431 at its riser 43 and the medial surface that metal shell 10 fits, produce the expanded support effect by salient point 431 and metal shell 10, hold effect with the button that increases first,

second clamping part

12,41, make whole fixture construction more firm.

As mentioned above, the utility model provides connector one preferable feasible fixture construction, so offer the application of novel patent in accordance with the law; Yet, above implementation and graphic shown in, be the utility model preferred embodiment, be not to limit to the utility model with this, be with, approximate with structure of the present utility model, device, feature etc., identical such as, all should belong to of the present utility model founding within purpose and the claim.
