Abstract

A radio housing ( 100 ) is formed of a front plate ( 102 ) having screw mount receptacles ( 222, 223, 224, 228, 229, 230 ) and first and second side plates ( 104, 106 ). The first and second side plates ( 104, 106 ) have a plurality of non-symmetrical, three-dimensional (3-D), dovetail sections ( 108, 110, 112, 114 ) for aligning and capturing the screw mount receptacles ( 222, 223, 224, 228, 229, 230 ) of the front plate ( 102 ). The front plate ( 102 ) and first and second side plates ( 104, 106 ) are formed of an injection molded thermoplastic material. The three pieces ( 102, 104, 106 ) are coupled together. The three-piece injection housing formed of injunction molded materials allows the housing ( 100 ) to be customized to specific customer requests not currently available with past overmolded materials.

First claim

We claim:

1. A housing assembly for a portable radio, comprising:
three individual piece parts comprising a front plate, a first side plate and a second side plate;
the front plate having six screw mount receptacles located on an interior surface, wherein first and second screw mount receptacles are located at a top section, third and fourth screw mount receptacles are located at a mid-section, and fifth and sixth screw mount receptacles are located at a bottom section of the interior surface;
the first side plate having a push-to-talk (PTT) aperture and having a first dove tail section, the first dove tail section being three-dimensional, non-symmetrical and curved along a lengthwise edge (y-axis), and a second dove tail section, the second dove tail section being three-dimensional, non-symmetrical and curved along the same lengthwise edge (y-axis) of the first side plate, and
a first gap formed between the first dove tail section and the second dove tail section along the lengthwise edge (y-axis) of the first side plate, the first and second dove tail sections being located between the front plate and first side plate;
the second side plate having a third dove tail section, the third dove tail section being three-dimensional, non-symmetrical and curved along a lengthwise edge (y-axis) of the second side plate, and a fourth dove tail section, the fourth dove tail section, the fourth dove tail section being three-dimensional, non-symmetrical and curved along the same lengthwise edge (y-axis) of the second side plate, and a second gap formed between the third dove tail section and the fourth dove tail section along the lengthwise edge (y-axis) of the second side plate, the third and fourth dove tail sections being located between the front plate and second side plate; and the first gap between the first and second dove tail sections for capturing the third screw mount receptacle; and the second gap between the third and fourth dove tail sections for capturing the fourth screw mount receptacle.

2. The housing assembly of claim 1 :
wherein each dove tail section comprises first and second hooks, each hook for aligning with and capturing a screw mount of the front plate.

3. The housing assembly of claim 1 :
the first dove tail section being longer than the second dove tail section on the first side plate; and
the third dove tail section being longer than the fourth dove tail section on the second side plate.

4. The housing assembly of claim 3 , wherein:
the first dove tail section on the first side plate being same length as the third dove tail section on the second side plate; and
the second dove tail section on the first side plat being the same length as the the fourth dove tail section on the second side plate.

5. The housing assembly of claim 1 , wherein the front plate and first and second side plates are made of injection molded material without an overmold material.

6. The housing assembly of claim 1 , wherein the front plate and first and second side plates are made of different injection molded materials having different chemical properties.

7. The housing assembly of claim 1 , wherein the front plate and first-and second side plates are different colors.

8. The housing assembly of claim 1 , wherein the front plate is securable to a chassis via the screw mounts, and the first and second side plates are securable to the front plate without having to interconnect to the chassis.

9. The housing assembly of claim 1 , wherein tolerance slack between the front plate and the first and second side plates is taken up, once mounted to a chassis, and tolerances between the screw mounts and the chassis are taken up when mounted to the chassis.

10. The housing assembly of claim 1 , wherein each dove tail section comprises first and second hooks, each hook for aligning with and capturing a screw mount of the front plate, the first, second, third and fourth dove tail sections of the first and second side plates thereby capturing all six screw mount receptacles of the front plate.

11. The housing assembly of claim 1 , wherein the three piece parts couple and uncouple for verification of design tolerances prior to mounting on a portable radio chassis.

12. The housing assembly of claim 1 , wherein the three piece parts assemble and disassemble without a chassis to verify proper interconnect and fit between the three piece parts.

13. The housing assembly of claim 1 , wherein the first and second side plates mount to a portable radio chassis and then the front plate is screwed to the portable radio chassis.

14. A two-way radio housing, comprising: three individual piece parts comprising a front plate, a first side plate and a second side plate; and
the front plate having screw mount receptacles and first and second side plates, the first and second side plates having a plurality of non-symmetrical, three-dimensional (3-D), dovetails for aligning and coupling to screw mount receptacles of the front plate, and wherein the front plate and first and second side plates are formed of an injection molded thermoplastic material without an overmolded material; and wherein the plurality of non-symmetrical, 3-D, dovetails comprise:
a first dove tail section and a second dove tail section formed on the first side plate with a gap formed therebetween, the first dove tail section being longer than the second dove tail section, the first and second dove tail sections being located between the front plate and the first side plate;
a third dove tail section and a fourth dove tail section formed on the second side plate with a gap formed therebetween, the third dove tail section being longer than the fourth dove tail section, the third and fourth dove tail sections being located between the front plate and the second side plate;
the first dove tail section on the first side plate being same length as the third dove tail section on the second side plate; and
the second dove tail section on the first side plat being the same length as the fourth dove tail section on the second side plate.

15. The two-way radio housing of claim 14 , wherein one of the first and second side plates has a push-to-talk (PTT) aperture formed therein.

16. The two-way radio housing of claim 14 , wherein the injection molded thermoplastic material comprises an injection molded thermoplastic polymer.

17. The two-way radio housing of claim 14 , wherein the front plate and first and second side plates are not formed of any overmolded thermoplastic materials.

18. The two-way radio housing of claim 14 , wherein two of the screw mount receptacles of the front plate are coupled and retained within corresponding gaps of the first and second side plates.

19. The two-way radio housing of claim 14 , wherein the front plate and first and second side plates are made of different injection molded materials having different chemical properties.

20. The two-way radio housing of claim 14 , wherein the front plate and first and second side plates are different colors.

21. The two-way radio housing of claim 14 , wherein the front plate is securable to a chassis via the screw mounts, and the first and second side plates are securable to the front plate without having to interconnect to the chassis.

22. The two-way radio housing of claim 14 , wherein tolerance slack between the front plate and the first and second side plates is taken up, once mounted to a chassis, and tolerances between the screw mounts and the chassis are taken up when mounted to
