technical field

The utility model relates to a structural improvement of a connector, in particular to a stable snap-in structure design applicable to male and female connector seats.

Background technique

With the increasing development of science and technology, the electronic products currently sold on the market are all moving toward miniaturization, refinement or ultra-thin evolution; and what the utility model improves is the current notebook computer NB and personal digital assistant PDA. In electronic products such as mobile phones and mobile phones, the connector structure must be used when the screen is connected to the host cable. The connector component can be roughly divided into male and female seats. It is connected with the male and female sockets respectively, and then plugged and connected through the male and female sockets of the connector. A type with a considerable number of terminals; in other words, the precision of the male and female connectors must be quite high to ensure that the terminals are reliably connected;

What this utility model is to discuss is the problem of stable connection after the male and female connectors are connected and plugged in;

The connection strength of the connector is very important in the use of the aforementioned electronic products. For example, it is often encountered that after a period of use of the electronic product, the video on the screen often has a line noise or color Variation occurs; the reason is usually that the connector connecting the screen and the host cable is loose, resulting in poor screen video, especially the cable of the flip-up screen is most likely to cause damage to the connector after multiple pulls. Loose and affect video; Incidentally, the outer parts of the male and female connectors are usually made of metal sheets, which can be used to shield the negative GROUND PIN or grounding sheet. The degree of close contact between the male and female connectors shielding the negative pole will affect the stability of the video;

Therefore, the industry researched and developed that the structure of the formed tab 111 on the female seat 11 of the connector 10 is usually formed by direct stamping technology. After the male and female seats 12 and 11 are inserted and combined, the tab 111 can be connected with the male seat 12, the end face 121 fits together as shown in Figure 5, and thereby increases the degree of close joint between the male and female seats 12, 11 to shield the negative pole; After the 12 and 11 phases of the male and female sockets are plugged in, the looseness of the connector 10 is improved and the tightness of the shielded negative contact is quite limited;

For this reason, the industry continues to research and develop the connector 10 on the male and female seats 12 and 11, which are separately provided with tabs 111 and protrusions 122. As shown in Figure 6, after the male and female seats 1211 are plugged and combined, the transparent The clamping tab 111 and the clamping protrusion 122 of the female seat 12 are buckled and restricted; that is, the clamping protrusion 122 structure restricts the clamping tongue 111 from moving out and loosening, so that the situation of loosening can be improved to a considerable extent; However, the tabs 111 of the male and female seats 12 and 11 of the connector 10 are still in contact with the end face 121 as shown in Figure 6, and the protruding degree of the card protrusion 122 is quite limited. The pull strength and the contact tightness of the shielded negative electrode are still quite limited, and cannot completely solve the aforementioned connector defects;

It is worth mentioning that the male and female connectors of the aforementioned connectors may undergo multiple disassembly and assembly from production to use; When the connector is assembled with the host or the screen, it will also undergo multiple plug-in and pull-out tests; and when using electronic products, it may also be plugged in and out due to maintenance; and the tongue of the aforementioned connector, after many times of After plugging and unplugging, its elasticity may also be greatly reduced, and the protrusions will also be worn, which will affect the connection between the male seat and the female seat, the resistance strength and the close contact degree of the shielded negative electrode;

In other words, if the technical bottleneck can be broken through, the locking structure of the male seat and the female seat of the connector can be further designed so that the male seat and the female seat can be firmly inserted, the tensile strength is good, the negative contact of the shielding is tight, and it can withstand Features such as multiple plugging and unplugging must be able to solve many defects of traditional connectors and meet the actual needs of the industry.

The female base 20 has an insulating member 21, on which a predetermined number of terminal pins 22 (for wiring connection) are arranged, and one end of the terminal pins 22 is formed on the insulating member 21 as a contact point 221 Formed into a metal frame 23 structure through the metal sheet, and the metal frame 23 is covered and arranged on the outside of the insulating member 21 to form the shielding negative electrode (ground sheet) of the female base 20, and the inside of the metal frame 23 is just shaped as The structure of the slot 231; it is worth noting that the utility model is especially formed with a plurality of snap-in shrapnels 24 on the end surface of the metal frame 23 of the female base 20, and the snap-in shrapnels 24 extend toward the inside of the slot 231, and are embedded in the snap-in shrapnel The end surface of 24 is convexly formed with a structure of resisting convexity 241; moreover, there are a plurality of pressure ribs 25 concavely formed on the end surface of the metal frame 23 toward the direction of the slot 231;

The male seat 30 has an insulating member 31, one end of the insulating member 31 is formed into a plug-in portion 311, and a predetermined number of terminal pins 32 (for wiring connection) are arranged on the insulating member 31, and the terminal pins 32 The contact point 321 is formed on the socket part 311 of the insulating member 31; the metal insert 33 is formed from a metal sheet, and the metal insert 33 is arranged on one end surface of the insulating member 31 and its insert part 311 to form a male seat 30 shielding negative electrode (grounding piece); it is worth noting that the utility model is especially in the male seat 30, the metal insert 33 is located at the position of the insertion part 311 and has a snap-in groove 34;

Accordingly, the plug-in portion 311 of the male seat 30 of the connector can be inserted and combined with the slot 231 of the female seat 20, and the terminal contact points 221, 321 of the male seat 30 and the female seat 20 can also be contacted and combined; It should be noted that during the insertion and coupling process of the male and female seats 20 and 30, the protrusion 241 of the snap-in elastic piece 24 located on the female seat 20 can be slidably inserted into the engaging groove 34 of the metal insert 33 of the male seat 30, A stuck state is formed.

Through the above description, it can be seen that the engagement strength of the male and female connectors 20, 30 of the utility model connector is achieved through the engagement of the protrusion 241 of the engagement spring 24 and the engagement groove 34. Compared with The traditional buckle design and the convex buckle design have completely different functions and strengths; the description is as follows:

First of all, in terms of bonding strength, when the male and female connectors 20 and 30 of the connector are plugged and combined, the utility model engages with the engaging groove 34 of the male connector 30 through the engaging elastic piece 24 of the female connector 20 . And the protrusion 241 of the engaging spring 24 fits (sucks) in the engaging groove 34, as shown in FIG. 3 ; therefore, the strength of the engaging joint of the utility model is better than that of the conventional tongue 111 and the flat end surface 121. As shown in Figure 5 or the limit of the tongue 111 and the protrusion 122 is significantly improved as shown in Figure 6; The pressing ribs 25 are abutted against the metal insert 33 of the male seat 30 to strengthen the additional tightness between the metal frame 23 and the metal insert 33 as shown in FIG. 4; it is worth noting that when the male, When the female base 20, 30 is to be disassembled and separated, when the general pulling force is applied to the male and female bases 20, 30, the protrusion 241 of the embedded shrapnel 24 cannot be separated from the embedded groove 34; Only when the pulling force is applied can the resisting protrusion 241 be pulled out of the engaging groove 34 smoothly; in other words, the resisting protrusion 241 cannot be separated from the engaging groove 34 due to general pulling force, so that the male and female seats caused by slight pulling can be effectively prevented. 20, 30 detachment or unstable connection;

Furthermore, in terms of resistance to repeated plugging and unplugging, the utility model has a protrusion 241 structure formed on the snap-in shrapnel 24, and the protrusion 241 structure is an arc-convex shape; therefore, the connector male and female seats 20, When the 30 phases are mated, the snap-in shrapnel 24 can be smoothly slid into the snap-in groove 34 to form a snap-fitting by the arc-shaped protrusion 241; The arc-convex structure of the embedding protrusion 241 can be smoothly disengaged from the engagement with the embedding groove 34. It is worth noting that the tight combination design of the male and female seats 20, 30 of the present utility model does not depend entirely on the embedding of the shrapnel 24. The elastic force is maintained (but through the engagement of the protrusion and the engagement groove and the compression of the pressure rib), so even if the insertion and extraction are repeated many times, the engagement elastic piece 24 will not be damaged or seriously reduced. Elasticity;

Finally, in terms of the degree of electrical tightness for shielding the negative electrode, the metal frame 23 and the metal insert 33 of the male and female seats 20, 30 of the present invention, in addition to being in close contact with the engaging groove 34 through the protrusion 241, The pressing ribs 25 are also designed as the tight contact and pressing between the metal frame 23 and the metal insert 33 , so the degree of electrical tightness of the shielded negative electrode is quite good.

From the above description, it can be seen that the engaging structure of the connector of the present invention is different from the tongue structure of the traditional connector, through the stable engaging design of the inserting shrapnel 24 of the present invention, the protrusion 241 and the inserting groove 34 , and the cooperation of the pressurizing ribs 25, the male and female seats 20, 30 of the connector of the present invention can completely solve the defect that the traditional connector is easily pulled and affects the degree of connection.
