Sealing a socket

The present invention relates to a seal for a plug socket of a mobile phone housing composed of two half-shells in order to achieve an IP protection class, wherein the plug socket is arranged in the parting plane of the half-shells.

Modern mobile phones are not only used in the office, in the car and on the street, but increasingly also during various leisure activities where there is a risk that solid objects, dust and moisture can penetrate the devices.

The aim of mobile phone development is therefore to develop mobile phones that can be assigned an IP protection class. The IP (= International Protection) protection class classifies the systems according to their degree of protection against the ingress of solid objects, dust and moisture. The IP designation consists of two numbers, with the first number indicating the degree of protection against dust and the second number indicating the degree of protection against moisture. The first number can vary from 0 to 6 and the second number from 0 to 8. The number 0 does not correspond to any degree of protection. For example,

For example, a 5 as the first digit means that the device is protected against dust and a 6 as the first digit means that the device is completely dustproof. A 4 as the second digit means that the device is protected against splash water, while a 5 as the second digit means that the device is protected against a water jet.

The object of the present invention is to provide a mobile phone with an IO connector socket, in which the connector socket is sealed in such a way that a high IP protection class is achieved.

This object is achieved according to the invention for the seal mentioned at the beginning in that a circumferential insert seal with sealing lips is provided between the half shells and the plug socket, that a substantially mushroom-shaped sealing plug is provided for insertion into the plug socket, which has a circumferential sealing lip on the underside of its head, which presses against the insert seal when the sealing plug is pressed in. 10

The sealing according to the invention ensures a secure sealing of the socket of the �IΩ plug connection when not in use.

Further expedient developments and refinements of the invention emerge from the subclaims and from the following description of an embodiment with reference to the drawings.

Figure 1 shows the position of the socket 3 to be sealed in the parting plane of the upper half-shell 1 and lower half-shell 2 forming the mobile phone housing. The socket 3 is attached to the circuit board 4. In the front area of the socket, an insert seal 5 runs between the edges of the socket 3 and the edges of the upper shell 1 and the lower shell 2. This insert seal 5 has several sealing lips 6. The insert seal 5 is guided in sealing grooves in the lower and upper shells.

The detailed views A and B in Figure 2 and Figure 3 show in detail the seals between the mobile phone housing and the socket 3. The insert seal forms a free-form surface on the outside which adapts to the housing design.

The actual sealing of the socket when not in use or when the mobile phone is being used under difficult environmental conditions is carried out by the sealing plug 7. This is essentially mushroom-shaped with a head. The peripheral outer edges of the head are adapted to the external conditions of the upper shell 1 and the lower shell 2, as can be seen from Figure 4. Between the outer edges of the head and the actual stem of the sealing plug 7 there are peripheral sealing lips 8 which, when the sealing plug 7 is pressed in, press against the free-form surface of the insert seal 5. This peripheral sealing lip 8 deforms the insert seal 5 when the sealing plug 7 is inserted, thus ensuring the necessary sealing effect.

Sealing plug 7 and insert seal 5 are adapted to the housing in such a way that a type of labyrinth seal is created, which increases the sealing effect. In this case, locking cavities prevent a capillary effect.

The advantages of the seal according to the invention are the sealing of a free-form surface, with the sealing forces acting only slightly in the direction of joining of the housing parts. The sealing effect is achieved along a free-form surface by a combination of labyrinth and compression seals, sealing between the separation between the housing and the plug socket. At the same time, a sealing effect is achieved by the combination of a sealing plug 7, which consists of a hard rubber component, and the housing seal, which consists of a soft rubber component, for sealing the plug socket itself.
