Description

Improved connector fixing structure

technical field

The utility model relates to the improvement of the fixing structure of the connector, and aims to provide a combined fixing structure that allows the connector to change the fixing position.

Background technique

In order to increase the data storage capacity and the convenience of reading and transferring data, electrical devices such as general consumer electronics products often have a memory card connector on the device itself, so that the electrical device can communicate with the established specifications through the memory card connector. The memory card is connected and operated, or the device itself is equipped with a signal line connector for the insertion and connection of the relevant signal transmission line, so that the electrical device can be connected and operated with other electrical devices through the signal line connector.

The above-mentioned memory card connectors and transmission line connectors (hereinafter collectively referred to as connectors) are mostly directly constructed on the printed circuit board of the electrical device, and as shown in FIG. The space-limiting structure of the memory card 20 shown above, and as an electromagnetic wave shielding structure, the metal shell 10 is generally fixed on the printed circuit board 30 by means of welding and adhesion, in order to achieve the combination with the printed circuit board 30 and the grounding The double effect of the connection of lines.

The fixing structure of the conventional connector is shown in Figure 1 and Figure 2, and the fixing part 11 used to fit the printed circuit board 30 is integrally stamped and formed on the side of its metal shell 10, and the fixing part 11 is connected to the printed circuit board. The fixed point 31 of 30 is combined, so that the metal shell 10 of the connector can be accurately welded and fixed at the predetermined fixed position; in addition, in the development process of general electrical devices before mass production, or after mass production, It is inevitable that there will be slight changes to the internal circuit layout, that is, the position of the fixed point used to install the connector may need to be adjusted slightly; however, the conventional fixed structure is mostly integrally formed with the metal shell, and cannot be adjusted at all. The corresponding position of the fixed part will not only hinder the design and development, but also may have to change the design of the entire metal shell or the entire connector, resulting in unnecessary cost expenditure, and even seriously affecting the production capacity of the product.

Utility model content

In view of this, the purpose of the present invention is to provide a combined fixing structure that allows the connector to change the fixing position.

The technical solution adopted by the utility model is: the combined fixed structure is basically composed of the metal shell of the connector and the positioning piece installed on the metal shell; wherein, the metal shell is respectively provided with a first , the second limiting part, and the positioning part is also provided with the first and second locking parts corresponding to the first and second limiting parts, and the first and second limiting parts are used to limit the first and second locking parts respectively.

Detailed ways

The fixed structure of the connector of the utility model is improved. The basic structure of the fixed structure is shown in Figure 3 and Figure 4, which is formed by the metal shell 40 of the connector and the positioning member 50 installed on the metal shell 40. The metal shell 40 is provided with first and second stoppers that can limit the movement of the positioning member 50 at an appropriate position. As for the second limiting part, it is composed of two grooves 412 which are arranged on the side wall 41 of the metal shell 40 and protrude from the side wall 41; the positioning member 50 is provided with a A fixed part 51 that fits together, and a vertical plate 52 that is attached to the side wall 41 of the metal shell 40. The first engaging portion is an inclined portion 521 that protrudes from the upper part of the vertical plate 52 toward the metal shell 40. The two locking parts are formed by the extension parts 522 extending from the upper parts on both sides of the vertical plate 52 toward the two outer sides.

During specific assembly, the positioning member 50 is moved from above the metal housing 40, and slides in the second channel 412 by the vertical plate 52, and the extension part 522 is stuck on the top of the second channel 412, so that the positioning member 50 is no longer Move down, and the positioning piece 50 cannot move left and right by the restriction of the two grooves 412, and the tab 411 is also locked on the top of the slope 521, so that the positioning piece 50 is difficult to move upwards, so as to use the first limit The positioning part (protruding piece 411) and the second limiting part (groove 412) restrict the first locking part (inclined part 521) and the second locking part (extending part 522) respectively to fix the positioning member 50 on the on the metal case 40.

Furthermore, as shown in the second embodiment of Fig. 5 and Fig. 6, the first limiting part of the metal shell 40 is formed by the protruding piece 411 located at the lower part of the side wall 41 of the metal shell 40, as for the second The position-limiting part is also formed by the groove 412 provided on the side wall 41 of the metal housing 40 and protruding from the side wall 41, and the first locking part of the positioning member 50 is the lower part of the vertical plate 52 facing the metal housing. 40 protruding inclined portion 521, the second locking portion is formed by the extension portion 522 extending from the lower parts of both sides of the vertical plate 52 toward the two outer sides; The plate 52 slides in the groove 412, and the first stopper (protrusion 411) and the second stopper (slot 412) can also be used to control the first locking part (slope 521) and the second locking part respectively. The locking part (extending part 522 ) fixes the positioning part 50 on the metal shell 40 .

With this structure, a combined fixing structure is obtained, which can be combined into a connector after the metal shell 40 and the positioning member 50 are respectively processed and formed, and used for welding and bonding with the printed circuit board or other fixing methods (such as screws). Locking or fixing with bolts, etc.) fixed structure; especially, when the fixed point position of the printed circuit board changes, only the position of the fixed part of the positioning part needs to be changed, that is, the position of the fixed part and the position of the fixed point must be in line with each other. The positioning part is assembled on the metal shell, that is, the fixed position of the connector can be adjusted without changing the original design of the metal shell, which effectively reduces the cost of materials and related development costs.

Furthermore, as shown in Figures 7 and 8, the positioning member 50 in the utility model is further provided with a bump 523 on the inner surface of its vertical plate 52 and the metal shell 40, and the bump 523 is connected to the metal shell. The body 40 produces an expansion effect to increase the locking effect of the limiting part and the locking part, so that the entire fixing structure is more stable; of course, the fixing part 51 can extend toward the outside of the side wall 41 of the metal shell, as shown in Figure 7 As shown; also as shown in Figure 8, the fixing portion 51 can also extend toward the inside of the side wall 41 of the metal housing, and the fixing portion 51 can also be further provided with a bump extending into the fixed point 61 of the printed circuit board 60 523, so as to increase the contact positioning effect with the printed circuit board 60.

As mentioned above, the utility model provides a better and feasible fixing structure for the connector, so an application for a new patent is submitted according to the law; however, the above implementation description and drawings are preferred embodiments of the utility model, not based This limitation of the utility model means that all similar and identical structures, devices, and features of the utility model should belong to the creation purpose of the utility model and the scope of the patent application.
