Description

Adjustable terminal waterproof connector

The present invention relates to a "waterproof connector with adjustable terminals" which can be finely adjusted for the male terminal and has a waterproof function.

As shown in Figure 10, the male connector (50) is generally used for electronic signal transmission and is formed by connecting a male end connector (50) and a female end connector. Mainly has a male terminal seat (51), the front end of the main body (511) of the male terminal seat (51) protrudes with a first ring edge (512), and the rear end protrudes with a second ring edge (513). The protrusions of the first ring edge (512) and the second ring edge (513) are separated, so that a first sleeve space can be formed inside the first ring edge (512) and the second ring edge (513) respectively. (514) and a second piercing space (515), and the main body (511) is pierced with a plurality of male terminal holes (516), so that the male terminal (52) crimped with the wire (53) can pass through all the After the second insertion space (515) is directly pressed into the male terminal seat (51) through the male terminal hole (516), the male terminal (52) is then inserted into the first through hole (516) to extend. In the sleeve space (514), the glue (54) is applied and packaged by means of a dispensing procedure, so that the male terminal (52) crimped with the wire (53) can be reliably fixed in the male terminal seat (51) , and the male terminal seat (51) is manufactured in one piece by using a mold, and the female terminal and the female terminal seat are also combined with each other in the same way to form a said female end connector.

However, the above-mentioned conventional structure still has the following problems in practical application: (1) The male terminal (52) is pressed into the male terminal seat (51), and then glue is dispensed to fix it directly , will result in that each of the male terminals (52) has no degree of freedom to adjust (that is, it cannot be offset up, down, left, right and rotation), when the number of pins (pins, male terminals 52) of the male end connector (50) is greater, the position and alignment between the pins are more important, so that the male terminal can be used to produce the male terminal. The mold of the seat (51) requires relatively high machining accuracy, and the production cost will increase accordingly, which is not conducive to the competition between industries; (2) the male and female connectors without any degree of freedom can be adjusted in the When connecting, it needs to be accurately aligned. If the male terminal (52) is bent, it may cause the male terminal (52) to be bent or directly broken. In addition to the normal use of the connector, it is also necessary to increase its strength when unplugging the connector next time. Therefore, it can be seen that the conventional connector, which requires great attention to the verticality of the docking, obviously has the problems of short service life and poor assembly convenience; (3) ) Although the glue (54) can fix the male terminal (52) on the male terminal seat (51), it cannot fix the connection between the male terminal (52) and the wire (53) An insulating waterproof effect is produced, so that the moisture in the environment will directly penetrate into the wire (53) from the opening behind the male terminal seat (51) through the second sheathing space (515), so that the Connectors are prone to failure or damage due to this.

Therefore, the inventor of the present invention has considered the idea of creation in view of this, and has designed it with years of experience. After many discussions and sample tests, and many revisions and improvements, the present invention is launched.

The rear end is provided with a jack, so that the jack is crimped with the wire, the spacer is an elastic body, and has a plurality of sleeve holes horizontally penetrating both ends of the spacer block, and the front hole wall of each sleeve is A first constriction is formed inward, and a second constriction is formed in the back hole wall. Using the characteristics of the cushion block to be elastic and expandable and deformable, the male terminal will be able to pass through all the holes in sequence when it is threaded and combined. After the second constriction and the first constriction of the sleeve hole, the leading section and the flange pass through the front end of the spacer block, and the spacer block rebounds after the male terminal is penetrated, so that the The front end of the first constriction and the rear end of the flange can abut against each other to prevent the male terminal from retreating and detaching, and the second constriction is elastically tightened on the On the wire, the connection between the male terminal, the wire and the pad can be more tight and firm, and also has a waterproof function. The male terminal seat has a body, and the front end of the body protrudes with a first ring, There is a second ring protruding from the rear end, and the first ring edge and the second ring edge are separated by the protrusions, so that a first sleeve space can be formed inside the first ring edge and the second ring edge respectively. and a second sleeve space, and a plurality of male terminal holes are penetrated on the body relative to the sleeve holes of the spacer block, and the male terminal holes are set to be larger in the rear and smaller in the front and slightly larger than the distance between the male terminals.

It is also possible to use the male terminal hole that is slightly larger than the distance between the flange and the lead section. It is designed so that there is a gap between the male terminal hole and the flange and the lead section after the male terminal is assembled and assembled, and the pad is glued through the glue dispensing process The block is fixed in the second sleeve space instead of directly bonding the male terminal, so that the male terminal can be formed by the formation of the gap and the elasticity of the spacer itself. It has degrees of freedom of offset and rotation in all directions, so that through the generation of the degrees of freedom, the male terminal can actively perform micro-adjustments to adapt to each other when the male and female connectors are connected, and the relative can be greatly adjusted. The requirements and dependence of the male terminal block on the machining accuracy of the forming die are reduced, and the male terminal will not be easily broken or broken because the male end connector and the female end connector are not sufficiently perpendicular when they are butted. Bending; thereby, the waterproof connector of the adjustable terminal can be formed.
